Most toaster ovens stop being useful the moment you own a real baking dish. The pan won’t fit, the chicken touches the top element, and you end up heating the big oven for a tray of vegetables. A truly large countertop oven solves that, but it’s a bulky thing to have on a counter, and the word “large” on a box doesn’t tell you much.
So we looked for ovens that say how big they are: a volume, an interior measurement, or a list of foods. Each of the seven here states a capacity in its listing, and most put XL, extra large or a size right in the title. For smaller or general options, start with our guide to the best toaster oven.

Quick verdict: the big oven to buy first
The Breville Smart Oven Air Fryer Pro is our best extra large toaster oven for most homes: it states its 16 by 13.5 by 7 inch interior, fits most 9-by-13-inch pans, and America’s Test Kitchen ranks the model highly recommended. For turkeys and large roasts, look at the Ninja Prestige Smart XL Pro. If you actually want two dishes at two temperatures, the Ninja Double Oven Pro makes more sense than one larger chamber.

What extra large really means on a toaster oven
There’s no standard for the term. One maker’s XL can be another’s mid-size, so look past the label. Three figures tell you more, and they don’t always agree.
Quarts. The number on the box looks exact, but it’s a measure of the empty cavity, not of what you can cook. HotKing shows this well: 28 quarts, with a stated fit of a 10-inch pizza. Toshiba gives 34 quarts and two 13-inch pizzas. Ninja’s 30.2 quarts is split between two ovens. Comparing these directly can mislead you.
Slices. The classic toaster oven measure counts how many pieces of bread fit in one layer, so it hints at the width and depth of the rack. Breville, the Ninja DT551 and Gourmia all state 9. That is a good figure to compare, even if you never make toast for nine.
Interior inches and pans. This is what you really need. If you own a 9-by-13-inch pan, look for that wording and remember the handles. Breville says most fit. Height matters for a whole bird, since a chicken placed close under a hot element can burn on top. America’s Test Kitchen says it directly: “The bigger the cooking space, the more food we could fit in it,” but it also warns these ovens “have a much larger footprint.” If you’re watching the budget more than the capacity, our budget toaster oven guide is the better place to start.
Our picks for the best extra large toaster oven
The order runs from strongest evidence and most useful size down to ovens with a narrower appeal or a thinner record. Where a pick rests on its listing alone, we say so.
1. Breville Smart Oven Air Fryer Pro BOV900BTR – The Roomy Oven With the Best Record
This is the one extra-large oven here with strong independent support behind it. America’s Test Kitchen’s August 2026 review of air-fryer toaster ovens names the BOV900 its winner, ranks it highly recommended, and says it “can also accommodate more food than our favorite air fryer.” Its air-fry basket gives nearly 175 square inches of room, by that review’s measure.
The listing calls the capacity extra large and backs that up with a number that actually helps: an interior of 16 by 13.5 by 7 inches. Breville says that fits 9 slices of bread, a 14-pound turkey, most 9-by-13-inch pans, 12-cup muffin trays and a 5-quart Dutch oven. A 13-inch pizza pan comes in the box, along with two racks, a broil rack, a roasting pan and a mesh basket.
This Black Truffle listing is a different color of the brushed-steel oven on our main toaster oven guide. We repeat the model on purpose, since a page about the biggest ovens would be less honest without the one with the best record. The review’s measured footprint is about 21.5 by 13.55 by 12.5 inches, so it needs real counter space.
Why we like it
- Interior dimensions stated, which most listings skip
- Highly recommended by America’s Test Kitchen as the BOV900
- Fits most 9-by-13-inch pans, per Breville
- Two-year limited warranty stated
Key specifications
| Model | BOV900BTR |
|---|---|
| Stated capacity | 16 x 13.5 x 7 in interior |
| What the listing says fits | 9 slices; 14 lb turkey; 9 x 13 in pans; 5 qt Dutch oven |
| Functions | 13, including air fry, dehydrate and slow cook |
| Power | 1800 W |
| Listing dimensions | 21.4 x 17.2 x 12.8 in (Amazon fields) |
| Warranty | 2 years |
Why we recommend it
It suits a household that bakes in real pans and wants an oven that may stand in for the big one on most weeknights. If you want the stainless finish, the main guide has that listing.
Skip it if you want two separate cooking zones; look at the Ninja Double Oven below.
Pros and cons
Pros
- Strong independent review of the model
- Clear interior size
- Plenty of accessories
Cons
- Large and heavy for a counter
- Same model appears on our main guide in another color
- No dual-zone cooking
2. Ninja Prestige Smart XL Pro DT551 – A Turkey-Size Oven With a Thermometer
Ninja puts XL in the name and gives a list you can picture: two 9-by-9-inch baking trays, 20 cookies, 9 slices of toast or 9 bagel halves on a rack, a 12-pound turkey, and up to 8 pounds of food in the air fryer. Its special feature is the Pro Cook thermometer, which the listing says detects temperature and lets you choose doneness.
A close relative has an independent report. America’s Test Kitchen rated the Ninja Prestige XL DT501 recommended, calling its interior spacious and relatively easy to clean, with good toast and broiling. Air frying was mixed there: frozen fries took almost three times longer than expected, and the oven had no auto-pause when the door opened. That review covers the DT501, not this smart DT551, so we can’t say the results carry over exactly.
This is a big machine. Amazon’s fields give about 20.2 by 17 by 13.3 inches and nearly 34 pounds, and those may include packaging. Clear the space before you buy, and check the manual for the clearance it needs around the oven.
Why we like it
- XL capacity spelled out in foods
- Thermometer included
- Two sheet pans and two wire racks
- Roast tray and air fry basket included
Key specifications
| Model | DT551 |
|---|---|
| Stated capacity | XL; volume not stated |
| What the listing says fits | 2 x 9 in trays; 20 cookies; 9 slices; 12 lb turkey; 8 lb air fry |
| Functions | 10, including dehydrate |
| Power | 1800 W |
| Listing dimensions | 20.22 x 17.09 x 13.34 in (Amazon fields) |
| Warranty | Not stated |
Why we recommend it
It suits someone who wants to cook whole birds and large roasts without running the big oven, and who likes a thermometer doing the watching.
Skip it if counter depth is tight, or you’re after fast fries; the related DT501 was mixed on air frying.
Pros and cons
Pros
- Very large stated capacity
- Thermometer built into the system
- Good accessory set
Cons
- Heavy, per the listing
- Review read covers a close relative, not this model
- Warranty not stated in the listing
3. Ninja Double Oven Pro Smart XL DCT801 – Two Small Ovens Instead of One Big One
A big oven isn’t always the answer. If what you actually want is the main and the side at the same time, this model splits the space. There are two independent ovens: open just the top for a quick snack, or open the full door to cook two meals two ways. Smart Finish syncs them so both end together, according to the listing.
The title gives 30.2 quarts in total, though remember that’s shared across two chambers. Ninja says it fits up to 6 pounds of wings, 6 salmon filets, a 4.5-pound chicken, family-size sheet pan meals and up to 6 slices of bread. A single turkey or a large roast won’t work the way it does in the single-chamber ovens on this page, so buy this for two smaller dishes, not one giant one.
We couldn’t open Ninja’s own product page, and we didn’t find a test of this exact model that we could read. So this pick rests on the listing. The 12 programs include Keep Warm and Dehydrate, and it comes with two sheet pans, two wire racks and an air fry basket.
Why we like it
- Two ovens run independently
- Smart Finish ends both together
- Quart total stated in the title
- Top section can be used alone
Key specifications
| Model | DCT801 |
|---|---|
| Stated capacity | 30.2 qt across two ovens |
| What the listing says fits | 6 lb wings; 4.5 lb chicken; 6 slices |
| Functions | 12, including dehydrate and keep warm |
| Power | Not stated |
| Listing dimensions | 18.7 x 17.2 x 14 in (Amazon fields) |
| Warranty | Not stated |
Why we recommend it
It suits a family that regularly needs two things at different temperatures, and a cook who would otherwise run two appliances.
Skip it if you want one wide chamber for a whole bird or a large pan; choose the Breville or the DT551.
Pros and cons
Pros
- Two zones in one footprint
- Top oven for small jobs
- Good accessory set
Cons
- Capacity is split between ovens
- No independent test read
- Wattage and warranty not stated in the listing
4. Nuwave Bravo XL Pro – The Wide Temperature Range
The Bravo XL Pro appeals to people who like to adjust things. The title gives a 30-quart size, and the listing states a range of 50 to 500 degrees F in 5-degree steps, three fan speeds, and top and bottom heaters you can set from 0 to 100 percent. There’s a smart probe, and 112 presets in all.
Here’s the caution. America’s Test Kitchen placed an earlier Nuwave, the Bravo XL 20801, in its not recommended group. That isn’t this Pro version, and the fan is described as redesigned here, but we would keep it in mind. Rtings has a review of this Pro model, but the full text is behind membership, so we did not rely on it. Nuwave’s claim that layers differ by 0 to 1 degree F is the maker’s own and we haven’t seen it verified.
This same oven appears, in a grill-combo listing, on our guide to air fryer toaster oven combos. We include it again because it’s one of few ovens that states both XL and a quart size in its title.
Why we like it
- 30 quarts stated in the title
- 50 to 500 F in 5-degree steps
- Adjustable top and bottom heaters
- Three fan speeds and a probe
Key specifications
| Model | Bravo XL Pro |
|---|---|
| Stated capacity | 30 qt |
| What the listing says fits | Not stated in the listing we read |
| Functions | 12 functions and 100 recipe presets, including dehydrate |
| Power | Not stated |
| Listing dimensions | 20 x 12.88 x 11.13 in (Amazon fields) |
| Warranty | Not stated |
Why we recommend it
It suits a tinkerer who wants to shape the heat, such as a thick pizza with more from below, and who will read the manual.
Skip it if you want an oven with a strong independent record; an earlier Bravo XL wasn’t recommended, so the Breville is the safer buy.
Pros and cons
Pros
- Very wide temperature range
- Heater balance you can set
- Size is clear in the title
Cons
- Earlier model not recommended by America’s Test Kitchen
- Maker claims unverified
- Same model on another guide in another listing
5. Toshiba ChefFry 34-Quart TL2-AC368LEA – The Biggest Quart Number Here
If you shop by the number, 34 quarts is the largest we kept on this page. Toshiba says the cavity fits a 10-pound chicken, two 13-inch pizzas or 6 slices of bread. The two-pizza figure presumably means two racks, so check rack heights if you plan on it, because stacking two pies doesn’t mean they’ll brown the same.
Pizza is the main selling point. Toshiba’s Dual-Temp mode is described as crisping from below while browning from above. The range runs from an 80-degree proofing setting up to 450 degrees F. The dual-layer door is said to stay 60 percent cooler than standard ovens, which is the maker’s own comparison, not a measured figure from anyone we read.
We read no independent review of this oven, so the pick rests on the listing. It is a separate oven from the Toshiba models on our other pages, and for pies alone you might also compare our toaster oven for pizza guide.
Why we like it
- 34 quarts stated in the title
- Fits two 13-inch pizzas, per Toshiba
- Low proofing setting
- Dual-layer glass door
Key specifications
| Model | TL2-AC368LEA |
|---|---|
| Stated capacity | 34 qt / 32 L |
| What the listing says fits | 10 lb chicken; two 13 in pizzas; 6 slices |
| Functions | 12, including dehydrate and proof |
| Power | 1750 W |
| Listing dimensions | 19.8 x 14.6 x 12.9 in (Amazon fields) |
| Warranty | Not stated |
Why we recommend it
It suits a pizza household, or a buyer who wants the most stated room in a single chamber with an established name on it.
Skip it if you want evidence beyond the listing; no independent review we read stands behind it.
Pros and cons
Pros
- Largest stated volume we kept
- Pizza mode
- Wide temperature range
Cons
- Rests on the listing
- Only 6 slices of bread stated, despite the size
- Warranty not stated
6. Gourmia GTF3588S 9-Slice French Door – Single-Pull Doors and Nine Slices
Gourmia states capacity the way toaster ovens traditionally do, in slices, and 9 is a big number. Six rack positions give you options for tall and flat foods. French doors that open together with a single pull mean a hot door isn’t dropping toward your waist, which some people prefer on a large oven.
The temperature runs from 90 to 450 degrees F, depending on the function. There are 12 functions, among them Air Fry, Slow Cook, Proof and Dehydrate, which the listing says can run up to 72 hours. An air fry basket, oven rack, baking pan and crumb tray are included, and the listing says the basket, rack and pan are top-rack dishwasher safe.
French doors deserve a look at recall news, since CPSC has acted on the doors of another maker’s ovens, as explained below. On November 5, 2026, CPSC announced a Gourmia recall of its GTF7530 9-slice French door air fryer oven, because the doors can close unexpectedly when bumped and burn a hand reaching for hot food. This pick is the GTF3588S, a different model number that is not on that recall, but it uses the same French door style, so check the model label on any Gourmia oven you own and keep up with notices. We also read no independent review of this oven, so the pick rests on the listing, and the listing gives neither a quart size nor a warranty.
Why we like it
- 9 slices stated in the title
- Six rack positions
- Single-pull French doors
- Accessories listed as top-rack dishwasher safe
Key specifications
| Model | GTF3588S |
|---|---|
| Stated capacity | 9 slices; volume not stated |
| What the listing says fits | 9 slices |
| Functions | 12, including dehydrate up to 72 hours |
| Power | Not stated |
| Listing dimensions | 18.5 x 15.5 x 13 in (Amazon fields) |
| Warranty | Not stated |
Why we recommend it
It suits someone who finds a drop-down door awkward and who toasts for a crowd.
Skip it if you want a stated volume in quarts or a known warranty term; the listing doesn’t give either.
Pros and cons
Pros
- Large slice count
- Flexible rack positions
- Doors open together
Cons
- No volume stated
- No independent review read
- Warranty not stated
7. HotKing KATO-28A1 Dual-Zone – XL on the Label, Honest Limits Inside
HotKing is a thin brand and the seller is the company’s own storefront, so we would treat this as the option to consider once you’ve looked at the others. What earns it a place is plain listing detail. It calls itself extra large at 28 quarts, and then gives the interior as 11.5 inches deep, 14 wide and 7.8 high.
Those measurements explain a limit worth noticing: the listing says it fits a 10-inch pizza and a 5-pound chicken. A 10-inch pizza is modest next to the 13-inch pizzas other listings promise, which shows why quart numbers alone can mislead. The dual-zone controls let you run different settings and sync their finish, and the French doors open together.
The title says ETL Rated, which is a safety mark, but we didn’t verify it beyond the listing. The free-of-PFAS statement is the seller’s own too. We read no independent review, and we found no recall under this name in the CPSC database when we searched.
Why we like it
- Interior dimensions stated
- Dual-zone sync
- French doors
- ETL rating named in the title
Key specifications
| Model | KATO-28A1 |
|---|---|
| Stated capacity | 28 qt |
| What the listing says fits | 10 in pizza; 5 lb chicken; 3 layers |
| Functions | 10, including rotisserie and dehydrate |
| Power | Not stated |
| Listing dimensions | 17.3 x 13.6 x 14.2 in (Amazon fields) |
| Warranty | Not stated |
Why we recommend it
It suits a buyer who wants dual zones and French doors together, and accepts a newer brand with less of a record behind it.
Skip it if you want a known maker, or plan on large pizzas; the Breville and Toshiba are better for those.
Pros and cons
Pros
- Clear interior size
- Dual zones
- Rotisserie included
Cons
- Amazon-first brand
- Sold by the brand’s own storefront
- Smaller pizza size than others
How to choose an oven this size
Measure the counter first. Amazon’s dimension fields on these listings run from about 17 to 21 inches on the widest side. Some may be boxed, so treat them as an upper guide. Allow for the door too; a drop-down door needs clearance in front, and French doors need it at the sides. Your manual will state how far the oven must sit from walls and cabinets, so read it before you decide where the oven goes, and never run it under a low cabinet unless the maker allows it.
One large chamber or two. One chamber suits a large pan or a turkey. Two suit a main and a side. A double oven can’t suddenly hold what a single large one can, so decide which problem you have.
Check the power. Several ovens here state about 1750 to 1800 watts. That’s a lot for a single kitchen circuit, so running one alongside a kettle or a coffee maker on the same circuit may trip the breaker. Plug directly into the wall if the manual says so.
Consider weight. The Ninja DT551 lists nearly 34 pounds. Don’t plan to lift it off a shelf every time you cook.
Decide what the extras are worth. Rotisseries, probes and presets are nice, but capacity is why you’re here. For a rotisserie specifically, compare our rotisserie air fryer oven guide. If your counter can’t take any of this, the best small toaster oven page is a more practical place to look.
What we left out, and why
The Oster Extra-Large 42L French door oven would be an obvious name here, but we left it out. CPSC’s September 2025 recall covers Oster French door ovens with model numbers TSSTTVFDXL, TSSTTVFDDG, TSSTTVFDMAF and TSSTTVFDDAF, because the doors can unexpectedly close. The Amazon listing we saw shows a different model number, and we can’t confirm how it relates to those. If you already own one of the named models, check CPSC’s page. We also passed on commercial countertop convection ovens, which aren’t built for most home kitchens, and on listings that showed as scarce when we checked.
How we chose these seven large ovens
We searched Amazon for in-stock countertop ovens from identifiable makers and kept those that state a capacity. Each lead offer was new when we checked. We skipped any exact listing already on another guide on this site, and allowed two models that appear elsewhere in another listing: the Breville, for its independent record, and the Nuwave, for stating XL and a quart size in its title. We read America’s Test Kitchen’s 2026 air-fryer toaster oven review. Rtings has reviews behind membership that we did not rely on. We checked the CPSC recall database by brand. We have not used these products ourselves, and we list no prices because they change.
Extra-large toaster oven questions, answered
How many quarts counts as extra large?
There’s no standard. The ovens here that give a number state 28 to 34 quarts, but a fit list or interior size tells you more than the quart figure alone.
Will a 9-by-13-inch pan fit?
Only some will. Breville says it fits most 9-by-13-inch pans. The other listings here don’t all say so. Measure your pan including its handles, and compare it with the stated interior before you buy.
Can an extra-large toaster oven replace my regular oven?
For many small meals it can do the job, but it won’t hold what a full-size oven holds, and it isn’t suited to several large dishes at once. Think of it as a second oven that saves heating the big one.
Do large toaster ovens use a lot of power?
The ones that state wattage here say 1750 to 1800 watts when running. That’s high for a countertop appliance, so check what else shares the circuit.
Is it safe to put one under a cabinet?
Follow the manual, since clearances differ by model. These ovens get hot on the outside and need room to vent. Don’t store anything on top unless the maker says you can.
Our final word on the best extra large toaster oven
Buy the Breville if you want the safest choice and the clearest size, the Ninja DT551 for big roasts, and the Ninja Double Oven if two dishes at once is the real goal. Whichever you choose, measure the counter and your favorite pan first. For more options at all sizes, return to our guide to the best toaster oven.
