The Best Baby Food Storage Containers: 4 Compared (and One to Skip)
We compared four baby food freezer trays and storage container sets on portion size, rigidity, lid seal, cube release, and cleaning.
The short version
Buy the Souper Cubes two tablespoon tray if you batch cook: the steel frame in the rim stops the sagging that causes freezer spills, the lid actually seals against freezer burn, and the one ounce wells match starter purees. Buy OXO Tot Baby Blocks if your bottleneck is handoffs to daycare or a partner, because each airtight container goes freezer to fridge to microwave to spoon without changing dishes, at the cost of freezer space. The WeeSprout tray is a fair value pick with clean cube release, a thinner flexing body, and a plainer clip-on lid, which makes it a good choice if you want two or three trays rather than one premium one. Skip the Mushie tray: it matches the budget tray on specs at close to premium money, and the lid staying put is the exact thing owners report going wrong. Most families end up with one tray for production and a few containers for transport, and that is a sensible outcome rather than overbuying. Best for: parents who cook purees in batches and want the freezer step to stop being the messy part of the week.

The verdict in 30 seconds
What mattered most
- Format
- Portion size
- Rigidity when full
- Lid and seal
- Release and cleanup
- Freezer space efficiency
Baby food storage splits into two jobs: freezing a big batch into portions, and carrying one portion from freezer to spoon. Different products win each job, so the useful question is which bottleneck you actually have. We compared four current options on portion sizing, how well a full tray holds its shape, lid sealing against freezer burn, cube release, and cleanup. Two are easy recommendations, one is a solid value with real compromises, and one asks premium money for a budget design.
A steel-framed silicone tray with a real lid that portions purees at one ounce and keeps working long after the baby food stage.
Best for: Batch cookers who fill trays on a weekend and want one tray that survives the puree months and keeps earning its shelf space afterward.
- Steel frame embedded in the rim keeps a full tray flat and level on the walk to the freezer
- Ten one ounce wells match early puree portions almost exactly
- Snug fitting lid gives better freezer burn protection than loose clip-on caps
- Fill lines molded into each well in tablespoons, teaspoons, and milliliters
- Oven safe at high heat and dishwasher safe, so it becomes stock and pesto gear later
- Backed by a lifetime warranty, which is rare in this category
- Costs more than the baby-aisle trays
- Silicone picks up garlic and curry smells over time and needs a periodic baking soda soak
- One ounce wells get small once baby is eating bigger portions, so you may want the larger tray too
Airtight single-portion containers that go freezer to fridge to microwave to spoon without ever changing vessels.
Best for: Families with a lot of daily handoffs to daycare, grandparents, or a partner, where a sealed labeled portion saves a step every time.
- Silicone-gasketed lids seal airtight and watertight, so a portion survives a diaper bag
- Six two ounce and four four ounce containers cover portion growth across the first year
- Snap-together trays keep containers upright and organized in the freezer
- Measurement markings molded into the container sides
- Microwave safe and top-rack dishwasher safe, with a shape that is easy to hold while feeding
- Individual containers with lids eat far more freezer space than loose cubes in a bag
- Carrot and tomato stain the plastic over time
- Gaskets need to come out of the lids periodically or they trap water and film
A capable budget tray with clean cube release and molded fill lines, held back by a thinner body and a plain clip-on lid.
Best for: Budget-conscious batch cookers who would rather own three trays than one premium tray, and who turn frozen portions over quickly.
- Ten 1.5 ounce wells with molded 0.5 and 1 ounce markings inside each one
- Reinforced base resists tipping better than a bare silicone mold
- Owners report clean single-cube release without twisting the tray
- Stacks under its own lid and fits a standard freezer shelf
- Cheap enough to buy two or three so you can batch cook in one session
- Thinner silicone flexes more when full, so a two-handed carry or a baking sheet is wise
- Rigid clip-on plastic lid seals less well than a gasketed cover and is the part most likely to crack
- The 1.5 ounce well is generous for early purees and stingy for a hungry ten month old
The prettiest tray in the aisle asks near-premium money for a budget design, and the lid is the part owners complain about.
Best for: Buyers who genuinely want the aesthetic and turn portions over within a couple of weeks, so lid sealing matters less.
- Best-looking colorways in the category
- Nine 1.5 ounce wells with measurement markings
- Food-grade silicone body, top-rack dishwasher safe
- Compact square footprint fits small freezer shelves
- Priced close to the steel-framed premium tray while matching the budget tray on specs
- The most common owner complaint is that the clip-on cover does not stay securely attached
- No reinforcement in the base, so a full tray flexes in transit
- Nine wells rather than the ten offered on either side of it in price

How we judged the field
We do not run a lab. What we do is read across independent testing, long-running product teardowns, and the aggregated pattern in owner reports, then weigh what actually matters once you are standing at the counter with a pot of cooled sweet potato puree and a baby who wants dinner.
Four things separated the good gear from the filler. First, portion size: purees for a six month old want roughly one ounce, and portions that only come in three ounce blocks force you to thaw more than baby will eat. Second, structure. A tray that sags when full sloshes puree across the freezer shelf on the walk from counter to door, and owners complain about this far more than about any other flaw. Third, the lid. Freezer burn is the main reason frozen puree gets tossed, and a lid that clips loosely or pops off under a stacked tray is not doing its job. Fourth, release: silicone should let a frozen cube pop out with thumb pressure from underneath, without twisting the tray or running it under hot water.
We also looked at what happens after the puree stage. Most families use freezer trays for about six months of baby food and then either retire them or keep them for stock, herb oil, and smoothie portions. Gear that has a second life is worth more than its sticker suggests.
Souper Cubes 2 Tablespoon Freezer Tray - buy
This is not marketed as a baby product, and that is part of why it wins. The two tablespoon tray gives you ten one ounce wells, which maps almost exactly to a starter puree portion, and the silicone is noticeably thicker than the baby-aisle competition. A steel frame is embedded in the rim, so a full tray stays flat and level when you carry it one-handed. Owners consistently describe this as the tray that stopped the spills.
The lid is the other reason to pick it. It is a snug fitting cover rather than a loose clip-on cap, which is what keeps ice crystals off the surface of the puree across weeks in a cold freezer. Fill lines are molded into each well in tablespoons, teaspoons, and milliliters, so you can portion consistently without a measuring spoon in the mix.
Two practical bonuses. The silicone is rated oven safe to a high temperature, so the tray does not retire when the puree stage ends: reviewers use it for stock cubes, pesto, herb butter, and baby-led weaning finger foods. And it carries a lifetime warranty, which is unusual in a category where most trays are treated as disposable. The company also sells a half cup tray, which is the natural upgrade once your baby is eating bigger portions.
The cons are real but small. It costs more than the baby-aisle trays, and silicone of any brand will pick up some smell from garlic and curry over time, so a periodic baking soda soak is part of ownership.
OXO Tot Baby Blocks Freezer Storage Containers - buy
Baby Blocks solve a different problem. Instead of freezing cubes and then bagging them, you freeze in the container the food will live in, so a portion goes freezer to fridge to microwave to spoon without ever changing vessels. The set pairs six two ounce containers with four four ounce containers, which covers the whole first year of portion growth, and each container sits in a snap-together tray so nothing tips.
The seal is the standout. Lids have a silicone gasket and lock down airtight and watertight, which means you can throw one in a diaper bag without lining it with paper towel. Measurement markings are molded into the sides. Everything is microwave safe and top-rack dishwasher safe, and the containers are the right shape to hold in one hand while feeding.
Where they lose to a tray is freezer real estate. Ten individual containers with lids take up far more space than ten cubes in a zip bag, so if you batch cook large and freeze deep, you will hit a wall. Owner reports also flag two nuisances: carrot and tomato stain the polypropylene over time, and the gaskets need to come out of the lids periodically or they trap water and film. Neither is a dealbreaker, but both are chores.
Buy this if your bottleneck is the daily handoff rather than freezer capacity. Buy the tray above if you cook in big batches. Plenty of families end up with both, and that is a reasonable outcome rather than a failure of choosing.
WeeSprout Silicone Baby Food Freezer Tray (1.5 oz Sections) - it depends
This is the value play, and for a lot of households it is the right call. You get ten 1.5 ounce wells, molded 0.5 and 1 ounce markings inside each one, a reinforced base that resists tipping, and a hard plastic clip-on lid, for meaningfully less than the premium trays. The flower-shaped footprint fits most freezer shelves, and the tray stacks under its own lid. Owners report clean cube release without twisting, which is the single most important thing a silicone tray has to get right.
The reasons it is a “depends” rather than a straight buy come down to two compromises. The silicone body is thinner than the steel-framed alternative, so a full tray flexes more in transit and wants two hands or a baking sheet underneath. And the lid is rigid plastic that clips on rather than a gasketed cover: it does the job, but it is a step down in freezer burn protection over a long stretch, and rigid clip lids are the part most likely to crack after a year of cold cycles.
The 1.5 ounce well size is also a specific bet. It is slightly generous for early purees and slightly stingy for a hungry ten month old. The company sells a three ounce version of the same tray, so pick the size that matches the stage you are actually in rather than assuming one tray covers the whole year.
Get this if you want a competent tray without spending much, or if you want two or three trays running at once so you can batch cook on a Sunday. Skip up to the steel-framed tray if you only want to buy once.
Mushie Baby Food Freezer Tray - skip
Nothing here is defective, and the color palette is genuinely nicer than anything else in the category. The problem is arithmetic. This is nine 1.5 ounce wells in food-grade silicone with a clip-on plastic cover, which is functionally the same product as the value tray above, at a price closer to the steel-framed premium tray. You are paying a design premium for a tray that does not do more.
The lid is where it gets harder to defend. The most common complaint in owner reports is that the cover does not clip on securely and works loose, which is exactly the failure mode that produces freezer burn and a puddle on the freezer shelf. When the whole reason to pay extra over a bare ice cube tray is the lid, a lid that does not stay put removes the argument.
There is also no reinforcement in the base, so a full tray flexes on the walk to the freezer, and nine wells is one fewer than the trays on either side of it in price. If you love the aesthetic and freezer burn is not a concern because you turn portions over in a couple of weeks, it will not let you down. For everyone else, the money is better spent either below it or above it.
Souper Cubes 2 Tablespoon Freezer Tray vs OXO Tot Baby Blocks Freezer Storage Containers: which should you buy?
These two are not really competitors, which is why we recommend both, but most people only want one to start.
Pick the Souper Cubes tray if your workflow is batch cooking. You steam and puree a big pot on the weekend, fill trays, freeze overnight, pop the cubes into a labeled zip bag the next morning, and reload the tray. Cubes stack densely, one tray refills endlessly, and the steel-framed rim is what makes the carry to the freezer uneventful. Cost per frozen ounce is dramatically lower this way, and the tray outlives the puree stage as kitchen gear.
Pick OXO Tot Baby Blocks if your bottleneck is the daily handoff rather than production. Grandparents, daycare, a diaper bag, a partner doing the 5pm shift: a sealed, labeled, single-portion container that goes straight into the microwave removes a step from everyone’s day. It also removes the freezer-bag stage entirely, which is the part most likely to get skipped when you are tired.
If you have freezer space and cook in volume, start with the tray. If you have a small freezer and a lot of handoffs, start with the containers. The tiebreaker for most families is capacity: the tray wins on throughput, the containers win on convenience, and neither wins on both.
What to look for
- Portion size that matches the stage. Roughly one ounce for early purees, two to three ounces by nine or ten months. A tray with wells that are too big forces you to thaw and waste.
- A rigid rim or reinforced base. Sagging silicone is the number one source of freezer spills in owner reports. Steel-framed rims or thick reinforced bases are worth the surcharge.
- A lid that seals, not one that rests. Gasketed covers and snug-fit lids beat loose clip-on caps for freezer burn protection. Check whether the lid stays on when the tray is stacked.
- Molded fill lines. Measurement markings inside each well let you portion consistently without extra dishes.
- Easy release. Good silicone releases one cube at a time with thumb pressure from below. If a tray needs twisting or hot water, it will crack eventually.
- Dishwasher and microwave ratings. Top-rack dishwasher safe is the practical minimum. Microwave safe matters only for containers you reheat in.
- A second life. Trays that are oven safe or sized for stock and pesto keep earning after the puree months end.
- Stain and odor realism. Silicone absorbs some smell, plastic stains from carrot and tomato, glass does neither but is heavy and breakable. Pick the tradeoff you can live with.
Our final take
The category is cheap enough that the real cost of a bad choice is spilled puree and freezer-burned food, not money. Two products avoid both. The Souper Cubes two tablespoon tray is the one to buy if you batch cook, because the steel-framed rim and the proper lid solve the two failures that actually happen, and the tray keeps working long after baby food ends. OXO Tot Baby Blocks are the one to buy if your day is full of handoffs, because a sealed single portion that goes freezer to microwave to spoon saves a step every single time.
The WeeSprout tray is a fair value pick and a smart way to own three trays instead of one, as long as you accept a thinner body and a plainer lid. The Mushie tray is the one to leave on the shelf: same well size and same clip-on lid concept as the budget tray, at close to premium money, with owner reports pointing at the lid as the weak spot.
Buy the tray if you cook in batches. Buy the containers if you hand food off. Buy both if the first month tells you that you need both.
Questions, answered
How long does homemade baby food keep in the freezer?
General guidance is up to about three months for frozen purees, and one to two days in the fridge once thawed, with meat and fish on the shorter end. Freezer burn is the practical limit rather than safety, which is why a tray with a sealing lid and prompt transfer into a labeled zip bag matters so much. This is general product information rather than nutrition or medical advice, so follow your pediatrician and your local food safety guidance for your specific situation.
Should I buy a tray or individual containers?
A tray is for production and a container is for transport. Trays let you freeze a large batch cheaply and densely, since you pop the cubes into a bag and reload the tray, but every serving needs a separate dish at feeding time. Containers skip that step and travel well, but ten of them with lids take up several times the freezer space of ten cubes. If you cook big and have freezer room, start with a tray. If your day is full of handoffs and your freezer is small, start with containers.
Is silicone safe for freezing and reheating baby food?
Food-grade silicone is stable across a very wide temperature range and is standard for freezer trays. Look for products described as food grade and free of BPA, BPS, PVC, and phthalates, and prefer trays where the lid is a separate part you can inspect. One practical note: reheat in a bowl or a microwave-safe container rather than in the tray unless the maker specifically rates the tray for it, and never pour boiling liquid directly into a filled tray.
Glass, plastic, or silicone: which storage material is best?
Each trades something. Silicone releases frozen portions cleanly and does not stain, but absorbs some odor from garlic and spices. Plastic containers are light, cheap, and microwave friendly, but carrot and tomato stain them permanently. Glass resists both stains and odors and reheats evenly, but it is heavy, it breaks, and freezing in glass requires leaving headspace so expansion does not crack the jar. For freezing, silicone trays are the easiest. For fridge storage and reheating, glass is excellent.
How do I stop freezer burn and stains?
Freezer burn comes from air contact, so fill wells close to the top, use the lid rather than plastic wrap, and move cubes into a squeezed-flat zip bag within a day or two of freezing instead of storing them in the open tray for weeks. Label the bag with the food and the date. For stains, rinse plastic containers in cold water before anything hot touches them, since heat sets carrot and tomato pigment. For silicone odor, soak in a baking soda solution or run the tray through a hot dishwasher cycle and air it out.
