A Mexican kitchen cooks in big batches and freezes the rest. A pot of pozole makes more than one dinner, a batch of mole paste lasts for weeks of enchiladas, salsa roja freezes in cup-sized portions, and fresh masa that will not be used today goes into the freezer flat so it thaws evenly. All of that needs a bag that seals tight, lies flat, and can be washed and used again.
Reusable freezer bags come in two main materials: thick, flexible silicone, which most makers rate for the microwave and dishwasher, and lighter PEVA plastic, which is usually freezer-only and hand-wash. This guide sorts the bags worth buying by what you freeze, and explains how to pack them so food keeps its quality.

Quick verdict: which reusable freezer bag to buy
For most kitchens, the best reusable freezer bags start with the Stasher half-gallon silicone bag: Stasher makes it from platinum food-grade silicone with its Pinch-Loc seal and rates it for the freezer, dishwasher, microwave and oven up to 425°F, so a portion of pozole can go from freezer to reheating in the same bag. If you need gallon bags for soups and marinades in quantity, the (re)zip gallon PEVA bags are lighter and come four to a pack. For freezing exact one-cup portions of salsa or mole, add Souper Cubes trays.
Read on for how each one seals, what the makers say they can handle, and which suits the way you freeze.

Our picks for the best reusable freezer bags
These seven cover the ways a home kitchen freezes food: thick silicone bags that can be reheated, light PEVA bags for bulk and marinades, stand-up bags that stay open while you ladle, and a silicone tray for freezing exact portions before they go into a bag. Every claim below comes from the maker’s listing.
1. Stasher Half Gallon Silicone Bag – Freezer to Reheat in One Bag
Stasher’s half-gallon bag holds 64 ounces, enough for a family portion of pozole, a quart of beans with their broth, or a few cups of shredded chicken for tinga. Stasher makes it from platinum food-grade silicone and closes it with its Pinch-Loc seal, a press-to-close rim it describes as leak-free.
The reason it leads this list is what Stasher rates it for: the freezer, the dishwasher, the microwave and the oven up to 425°F, plus sous vide. That means a frozen portion can thaw and reheat without being moved to another container. If you cook sous vide, our sous vide guide covers the circulators.
Stasher says the bag is free from lead, latex, phthalates, BPA and BPS; that is the maker’s claim. Care is simple: the dishwasher or warm soapy water, and Stasher warns against turning the bag inside out because it can tear. Stasher also lists a lifetime warranty that replaces bags damaged in normal use. The bag lies flat rather than standing, so fill it in a bowl or a wide jar.
Why we like it
- Freezer, microwave, dishwasher and oven to 425°F, per Stasher
- 64-ounce size suits family portions of soup or stew
- Platinum food-grade silicone with a Pinch-Loc seal
- Lifetime warranty for damage in normal use, per the listing
Key specifications
| Model | STHG00A |
|---|---|
| Material | Platinum food-grade silicone |
| Sizes/count | 1 bag, half gallon (64 oz) |
| Seal type | Pinch-Loc press seal |
| Freezer/microwave/dishwasher (maker) | Yes / yes / yes |
| Oven or heat use (maker) | Oven up to 425°F; sous vide |
| Stands up | Not stated |
Why we recommend it
It suits a cook who freezes soups, stews and beans in family portions and wants to reheat them without dirtying another dish.
Skip it if you need a lot of bags at once; it is sold singly, and silicone takes more freezer space than thin plastic.
Pros and cons
Pros
- Widest heat range of any bag here, per Stasher
- Dishwasher safe
- Lifetime warranty
Cons
- One bag per pack
- Do not turn it inside out to clean
- Does not stand on its own while you fill it
2. (re)zip Gallon Freezer Bags, 4-Pack – Light, Flat and Leakproof
(re)zip bags are made from PEVA, a flexible plastic that is much thinner and lighter than silicone. The maker describes it as food-grade, BPA-free and lead-free. Each gallon bag measures 11.5 by 12.75 inches and holds 16 cups, and the pack has four.
The closure is a double lock that (re)zip says clicks when it is sealed and is leakproof and airtight. That and the thin walls make these the bags to reach for when you want to freeze a lot of food flat: a gallon of broth, chile-marinated pork for al pastor, or the bones and onion ends you are saving for stock, which is one of the uses the maker suggests.
Read the care notes. (re)zip recommends hand washing, by sealing a drop of soap and water inside and shaking, though it says the bags are top-rack dishwasher safe on a standard setting. It says not to use them in the microwave, for sous vide or for high heat, and to cool foods before storing them. Plan to thaw and reheat in another container.
Why we like it
- Four gallon bags, 16 cups each, per (re)zip
- Double-lock closure the maker describes as leakproof
- Thin PEVA freezes flat and stacks
- Top-rack dishwasher safe on a standard setting, per the listing
Key specifications
| Model | BA935B-4ASRT |
|---|---|
| Material | Food-grade PEVA (BPA- and lead-free, per maker) |
| Sizes/count | 4 gallon bags, 11.5 x 12.75 in, 128 fl oz |
| Seal type | Double-lock zip closure |
| Freezer/microwave/dishwasher (maker) | Yes / no / top rack (hand wash recommended) |
| Oven or heat use (maker) | No; no sous vide or high heat |
| Stands up | Not stated |
Why we recommend it
It suits batch cooks who freeze big, flat bags of broth, beans and marinated meat and want more bags for the money than silicone gives.
Skip it if you want to reheat in the bag; the maker rules out the microwave and high heat.
Pros and cons
Pros
- Four gallon bags per pack
- Light and thin, so they freeze flat
- Leakproof double lock, per the maker
Cons
- Not for the microwave or heat
- Hand wash recommended
- Food must be cooled before storing
3. W&P Porter 50 oz Stand-Up Silicone Bag – Stands While You Ladle
Filling a floppy bag with hot soup is a two-person job. W&P’s Porter stand-up bag has a flat base so it stays upright on the counter while you ladle in menudo or salsa verde. It holds 50 ounces.
W&P says the bag is made from one piece of food-grade silicone with no glues or adhesives and with curved inside edges, which it says avoids the corners where buildup collects. It is rated for the dishwasher, microwave and freezer, and W&P says you can flip it inside out to clean it, unlike the Stasher. The front is clear so you can see and mark what is inside and when you froze it, and W&P also lists steaming and use in the oven or a multicooker. The listing does not give an oven temperature, so check with W&P before you bake in it.
W&P calls the bag plastic-free; that is the maker’s description of a silicone bag. The listing does not describe the closure type in detail, only that you should press out air before sealing.
Why we like it
- Stand-up base for hands-free filling
- One-piece silicone with no glues, per W&P
- Dishwasher, microwave and freezer safe, per the maker
- Can be turned inside out to clean
Key specifications
| Model | WP-PBSU50-MT |
|---|---|
| Material | Food-grade silicone, one piece |
| Sizes/count | 1 bag, 50 oz stand-up |
| Seal type | Not stated |
| Freezer/microwave/dishwasher (maker) | Yes / yes / yes |
| Oven or heat use (maker) | Oven and multicooker use listed; temperature not stated |
| Stands up | Yes |
Why we recommend it
It suits a cook who freezes liquids, such as soups, salsas and broths, and wants a bag that stays open while it is filled.
Skip it if you need to freeze bags flat and stack them; a stand-up base takes more room.
Pros and cons
Pros
- Stands up on the counter
- Clear front for labeling
- Turns inside out for cleaning
Cons
- Seal type and oven temperature not stated
- Single bag
4. Ziploc Endurables Silicone Pouches, 3 Sizes – Three Portions, One Pack
Ziploc’s Endurables line is its reusable silicone range, and this pack has three pouches: a small that holds up to 1 cup, a medium up to 2 cups and a large up to 8 cups. That spread matches how a kitchen actually freezes: a cup of adobo or salsa, two cups of rice, and a big bag of beans or picadillo.
Ziploc says the pouches go from freezer to oven to table and that the silicone is heat safe up to 425°F. They are microwave and dishwasher safe, close with what Ziploc calls Secure Seal Technology to help prevent spills, and have Cool Grab Tabs for handling them after heating.
The listing mentions a wide base with feet for standing, but that line refers to Ziploc’s Endurables containers, not these pouches, so we have not counted the pouches as stand-up bags.
Why we like it
- Three sizes: 1, 2 and 8 cups, per Ziploc
- Heat safe to 425°F, per the listing
- Microwave, dishwasher and freezer use
- Cool Grab Tabs for hot pouches
Key specifications
| Model | 343240 |
|---|---|
| Material | Silicone |
| Sizes/count | 3 pouches: 1, 2 and 8 cups |
| Seal type | Secure Seal closure |
| Freezer/microwave/dishwasher (maker) | Yes / yes / yes |
| Oven or heat use (maker) | Oven; heat safe to 425°F |
| Stands up | Not stated for the pouches |
Why we recommend it
It suits a cook starting out with silicone who wants a small, medium and large bag from a familiar brand in one pack.
Skip it if you mostly freeze gallon-sized batches; the largest pouch holds 8 cups.
Pros and cons
Pros
- Three useful sizes
- Oven, microwave and dishwasher rated
- Tabs for handling when hot
Cons
- Largest pouch is 8 cups
- Only three pouches
5. Souper Cubes 1-Cup Freezer Trays, 2-Pack – Exact Portions, Then Bag Them
Souper Cubes are not bags; they are lidded silicone trays. We include them because they solve the problem bags cannot: freezing liquids in exact, stackable portions. Fill the wells with salsa, mole, pozole broth or enchilada sauce, freeze, then pop the blocks out and move them into a reusable bag, which is exactly how Souper Cubes suggests using them alongside freezer or vacuum-seal bags.
Souper Cubes makes the trays from 100 percent food-grade, platinum-cured silicone with a steel-reinforced rim, so a full tray does not buckle when you carry it to the freezer. Each well has half-cup and one-cup fill lines in standard and metric. The maker rates the trays for the microwave, freezer and dishwasher, and the oven up to 415°F without the lid.
This pack has two 1-cup trays with lids. The listing does not say how many wells each tray has, so check the photos for the layout before you buy. Souper Cubes lists a one-year warranty against manufacturing defects.
Why we like it
- Half-cup and one-cup fill lines, per Souper Cubes
- Steel-reinforced rim and lids for stacking
- Oven safe to 415°F without the lid, per the maker
- Frozen blocks pop out to store in bags
Key specifications
| Model | FT-4X1-AQ-LD-2 |
|---|---|
| Material | Platinum-cured silicone, steel-reinforced rim |
| Sizes/count | 2 trays with lids, 1-cup wells |
| Seal type | Fitted lid (tray, not a bag) |
| Freezer/microwave/dishwasher (maker) | Yes / yes / yes |
| Oven or heat use (maker) | Oven to 415°F without the lid |
| Stands up | Flat tray |
Why we recommend it
It suits a cook who freezes sauces and broths and wants to pull out one cup at a time instead of thawing a whole bag.
Skip it if you want a single storage solution; the trays are a first step, and you still need bags or containers for long storage.
Pros and cons
Pros
- Exact, repeatable portions
- Rigid rim for carrying full trays
- Microwave, dishwasher and oven rated
Cons
- A tray, not a bag
- Number of wells per tray not stated
- Takes flat freezer space while freezing
6. Zip Top Silicone Set of 8 – Stands Open, Zips Shut
Zip Top’s design is different from a flat bag. Each piece has a self-supporting shape that stands upright and stays open for filling, then closes with a zip along the top, with no separate lid. This set of eight includes three cup sizes, three dish sizes and two bag sizes, so it covers small portions of salsa as well as larger leftovers.
Zip Top makes the pieces from 100 percent platinum silicone and says it is free of BPA, lead, PVC, latex and phthalates; that is the maker’s claim. They are rated for the microwave, freezer and dishwasher, and the listing title says they are made in the USA.
The cups and dishes are the useful part for freezing: they stand on a freezer shelf like a container but zip shut like a bag. The listing does not give the volume of each piece, so check the size chart in the photos if you are planning portions.
Why we like it
- Every piece stands up and stays open, per Zip Top
- Eight pieces: three cups, three dishes, two bags
- Platinum silicone, microwave, freezer and dishwasher safe
- Made in the USA, per the listing title
Key specifications
| Model | Z SET8A 03 |
|---|---|
| Material | 100% platinum silicone |
| Sizes/count | 8 pieces: 3 cups, 3 dishes, 2 bags; volumes not stated |
| Seal type | Zip closure |
| Freezer/microwave/dishwasher (maker) | Yes / yes / yes |
| Oven or heat use (maker) | Not stated |
| Stands up | Yes |
Why we recommend it
It suits a household that wants one matching set for freezing, leftovers and lunches, with pieces that stand on a shelf.
Skip it if you need large, flat bags for gallon batches; the standing shapes are better for small and medium portions.
Pros and cons
Pros
- Stands up and stays open
- Eight sizes in one set
- Made in the USA, per the listing
Cons
- Piece volumes not stated in the listing
- Oven use not stated
- Standing shapes do not stack flat
7. Qinline Reusable Bags, 24-Pack – Three Sizes in Bulk
If you want enough bags to rotate a full freezer, Qinline’s 24-pack gives you eight gallon bags (11 by 10-9/16 inches), eight sandwich bags (8-5/8 by 7-5/8 inches) and eight snack bags (8-5/8 by 5-1/4 inches). They are PEVA, like the (re)zip bags, with what Qinline calls an upgraded double closure that it describes as leak-proof.
The care advice is stricter than most. Qinline recommends hand washing and says the dishwasher will damage the double closure; it suggests a bottle brush and drying the bags propped over a mug. Qinline calls the bags non-toxic; that is the maker’s claim about its food-grade PEVA. The listing does not mention the microwave or heat, so treat them as cold-storage bags only.
The sandwich and snack sizes are handy for freezing tortillas in small stacks or chiles and herbs in small amounts, and the gallon bags take marinades and flat-frozen beans.
Why we like it
- 24 bags in three sizes, per Qinline
- Double closure the maker describes as leak-proof
- Food-grade PEVA, per the listing
- Clear bags to see what is inside
Key specifications
| Model | KD-SMZD-ZH039-01 |
|---|---|
| Material | Food-grade PEVA |
| Sizes/count | 24: 8 gallon, 8 sandwich, 8 snack |
| Seal type | Double zip closure |
| Freezer/microwave/dishwasher (maker) | Freezer (title) / not stated / hand wash only |
| Oven or heat use (maker) | Not stated |
| Stands up | Not stated |
Why we recommend it
It suits a cook who wants many bags in several sizes and does not mind washing them by hand.
Skip it if you want dishwasher-safe bags; Qinline says the dishwasher damages the closure.
Pros and cons
Pros
- Most bags of any pick
- Three sizes
- Thin, so they freeze flat
Cons
- Hand wash only, per the maker
- No microwave or heat use stated
- Less detail published than the bigger brands
How to choose reusable freezer bags
The right bag depends on what you freeze and how you reheat it. These are the points that matter.
Silicone or PEVA
Silicone bags are thick and heavy. Most makers rate them for the microwave and dishwasher, and some for the oven, so you can reheat in the bag. PEVA bags are thin plastic, much lighter, and freeze flat in less space, but their makers generally rule out the microwave and heat, and several recommend hand washing. Many kitchens use both: silicone for portions they will reheat, PEVA for bulk and marinades.
Seal type
Press seals like Stasher’s Pinch-Loc, zip closures like Zip Top’s and double-lock zips like (re)zip’s all aim to keep air and liquid in. For soups and sauces, seal the bag and lay it flat on a tray until it freezes, so a weak spot cannot leak across the shelf.
Size for how you eat
Freeze in the portion you will thaw. A half-gallon or gallon bag suits a family dinner of pozole or beans; one- and two-cup sizes suit salsa, mole and adobo. Trays like Souper Cubes make even portions you can bag afterward.
Stand-up or flat
Stand-up bags are easier to fill with liquids without help. Flat bags freeze into thin slabs that stack like files, which saves space in a crowded freezer. Once frozen, flat bags can be stood upright in a bin like files.
Packing for quality
Clemson Cooperative Extension’s guide to freezing prepared foods advises cooling food quickly before packing, for example by setting the pot in ice water and stirring, then freezing it promptly; packing food compactly to reduce air; using moisture- and vapor-resistant packaging; and leaving headspace in liquid dishes because they expand as they freeze. It also says the freezer should not go above 0°F.
How we picked these seven
We looked at the reusable freezer bags most often recommended and sold on Amazon, from silicone makers such as Stasher, Zip Top, W&P and Ziploc to PEVA makers such as (re)zip and Qinline. For each, we checked the Amazon listing for stock and model, then recorded only what the maker states: material, sizes and count, closure type, and whether it is rated for the freezer, microwave, dishwasher and oven. Claims such as BPA-free or plastic-free are reported as the maker’s claims.
We did not use these bags in our kitchen. Freezer guidance comes from Clemson Cooperative Extension, a university extension service. We left out listings from unbranded sellers and items that were scarce or not in stock when we checked, and we did not pad the list with near-identical PEVA packs.
Reusable freezer bag questions, answered
Are silicone bags good for the freezer?
Yes. Every silicone bag here is rated for the freezer by its maker. Silicone stays flexible when cold and many makers also rate it for the microwave and dishwasher, which plastic freezer bags generally are not.
How long can soup or stew stay frozen in a reusable bag?
Clemson Cooperative Extension lists stews and similar combination dishes at four to six months, and roasted meats at two to four months, when frozen at 0°F. It does not give separate times for salsas or sauces, so label every bag with what it is and the date it went in.
Can you freeze masa or tamales in reusable bags?
Yes; press it flat in a well-sealed bag and push out as much air as you can, which follows Clemson’s advice to pack food compactly with little air. Clemson’s guide does not list a time for masa or tamales, so freeze them in amounts you will use soon and label the date. Our guide to what tamales are covers the dish itself, and reheating Mexican leftovers covers bringing them back.
Can you microwave reusable freezer bags?
Only if the maker says so. Stasher, W&P, Ziploc Endurables, Zip Top and Souper Cubes rate their silicone for the microwave. (re)zip says its PEVA bags should not go in the microwave, and Qinline does not list microwave use.
How do you clean reusable freezer bags?
Follow the maker. Stasher, W&P and Zip Top are dishwasher safe; (re)zip recommends hand washing; Qinline says hand wash only. Dry bags fully, propped open, before storing them.
Our final pick for the freezer
Start with the Stasher half-gallon bag if you want one bag that goes from freezer to microwave or oven. Add (re)zip gallon bags for bulk batches and marinades, and Souper Cubes trays if you freeze salsas and mole in one-cup blocks. If you would rather have rigid containers, see our food storage containers and meal prep containers guides, and for long storage of meat, our vacuum sealer picks. For wrapping rather than bagging, see our beeswax wraps guide.
