Meal prep freezer molds are having a moment. Silicone trays that let you freeze individual portions of soup, sauce, rice, and proteins — then pop them out like ice cubes — have become the secret weapon of serious meal preppers. And the two names you'll see most often are Souper Cubes and Walfos.
Souper Cubes is the original, the internet-famous brand that went viral for good reason. Walfos is the most popular budget alternative, promising the same core functionality at a fraction of the price. The question is simple: does Souper Cubes justify costing more than three times as much?
Quick Verdict
Buy Souper Cubes (our pick) if: You meal prep in serious volume, freeze soups and stocks weekly, and want a set that will genuinely last for years. The platinum-cured silicone, steel-reinforced rims, precise fill lines, and tight-sealing lids are worth the money for heavy users. This is a buy-it-for-life kitchen tool.
Buy Walfos if: You're new to meal prep, want to try the concept without a big investment, or only freeze things occasionally. The Walfos trays work well for the price and will give you a solid year or two of service before the silicone starts to wear.
Our pick: Souper Cubes. The quality difference is real — thicker silicone, better lids, steel reinforcement, and precise 1-cup portions with fill lines. For serious meal preppers, the extra $54 buys you years of additional use. But the Walfos set is a perfectly good starter kit.
Our Pick 🏆 Souper Cubes Silicone Freezer Molds
$78.99 on Amazon (4-piece set)
Souper Cubes is the category-defining product — the silicone freezer mold that sparked a thousand meal prep TikToks. The 4-piece set includes a 2-cup mold, a 1-cup mold, a ½-cup mold, and a 2-tablespoon mold — each with its own tight-fitting lid. Every piece is made from 100% platinum-cured silicone, which is the food-safe gold standard. Unlike standard silicone, platinum-cured silicone doesn't leach odors or flavors and won't degrade as quickly over time.
The design details make the price easier to swallow. Steel-reinforced rims keep the molds from collapsing when you carry them full of liquid. Metric and imperial fill lines on the inside walls make portioning dead simple. The lids snap on securely enough to stack multiple trays without spills. And the easy-release flex means frozen blocks slide out in one piece without wrestling.
Oven-safe up to 415°F (without lids), dishwasher-safe, microwave-safe. These things are built to work hard in a busy kitchen.
Key specs: 4-piece set (2 cup, 1 cup, ½ cup, 2 Tbsp), platinum-cured silicone, steel-reinforced rims, snap-on lids, fill lines, oven-safe to 415°F, dishwasher-safe, BPA-free.

💰 Walfos Silicone Freezer Tray with Lid (4-Pack)
~$25.00 on Amazon (4-piece set)
The Walfos silicone freezer trays are the most popular budget alternative to Souper Cubes, and for good reason: they work. Each 1.5-cup tray comes with a lid, the silicone is food-grade and BPA-free, and the flexible material pops frozen portions out without much trouble. At roughly $6.25 per tray, the math is compelling.
Four trays give you 6 total cups of freezing capacity — enough for a batch of soup or a week's worth of sauce portions. The lids are snug enough for stacking but not quite as secure as Souper Cubes' snap-on design. The silicone is noticeably thinner, which means it's easier to flex but also less durable over the long haul. After about a year of regular use, some users report the silicone starting to stiffen or crack at the corners.
That said, for $25 you're getting a functional meal prep tool that does 80% of what Souper Cubes does at 32% of the price. For someone just getting into freezer meal prep, that's a compelling entry point.
Key specs: 4-piece set (1.5 cup each), food-grade silicone, snap-on lids, BPA-free, dishwasher-safe, freezer-safe.

Where Souper Cubes Wins
The silicone is genuinely better. This isn't marketing fluff. Platinum-cured silicone is a fundamentally different material from standard food-grade silicone. It's denser, more durable, doesn't absorb odors (your Souper Cubes won't smell like last week's chili forever), and won't degrade or stiffen after repeated freeze-thaw cycles. After two years of weekly use, Souper Cubes still feel like new. Walfos trays will start showing wear after about a year.
Steel-reinforced rims solve a real problem. If you've ever tried to carry a silicone mold full of liquid hot soup to the freezer, you know the struggle — the walls flop, the contents slosh, and you pray nothing spills. Souper Cubes' steel-reinforced rims keep the shape rigid when full. It's one of those details you don't appreciate until you use it.
The lid seal is night and day. Souper Cubes lids snap on with an audible click and stay put. You can stack three or four filled trays in the freezer without worrying about them shifting or leaking. Walfos lids fit fine, but they're looser — enough that stacking can be precarious, and you'll occasionally find frost inside the lid.
Portion variety matters. The Souper Cubes set includes four different sizes: 2 cups (entree portion), 1 cup (side or soup bowl), ½ cup (sauce or rice side), and 2 tablespoons (garlic, pesto, tomato paste). This range makes the set genuinely useful for everything from full freezer meals to tiny ingredient portions. Walfos gives you four identical 1.5-cup trays — good for soups and sauces, but you lose the flexibility to portion small ingredients.
Where Walfos Wins
The price is almost unbelievable. At ~$25 for four trays with lids, Walfos costs less than a single Souper Cubes tray (which averages $19.75 per piece). If you're on a tight budget or just want to dip your toe into freezer meal prep, the Walfos set is a no-brainer. You get 6 cups of total capacity — actually more than Souper Cubes' 3.75 cups — at a fraction of the price.
More total freezing capacity. Four 1.5-cup trays give you 6 cups of total freezing space versus Souper Cubes' 3.75 cups. If your primary need is freezing large batches of soup or stock in uniform portions, Walfos actually delivers more usable volume per dollar.
Great for the "try it" crowd. If you're not sure whether silicone freezer molds will fit your lifestyle, spending $78.99 to find out is a big ask. At $25, the Walfos set is an easy impulse buy. Use them for six months, figure out what works, then upgrade to Souper Cubes if you're hooked.
The $54 Question
The price difference between these two sets is $54. Here's the breakdown of what that extra money actually buys you:
The cost-per-use calculation matters. If Souper Cubes last 5 years of weekly use (260 uses) and Walfos last 2 years (104 uses), here's the math:
- Souper Cubes: $78.99 ÷ 260 uses = $0.30 per use
- Walfos: $25.00 ÷ 104 uses = $0.24 per use
Surprisingly close. The upfront cost difference looks massive, but spread over the lifespan of each product, Souper Cubes is only marginally more expensive per use — and you get better lids, steel reinforcement, oven-safe capability, and four different portion sizes.
Where Walfos pulls ahead: If you're not sure you'll stick with meal prep, or you only freeze things occasionally, the Walfos set makes more sense. At $25, even if you use it for a year and move on, the cost is negligible.
Durability Over Time
We looked at user reviews after 6, 12, and 18 months of ownership for both products. The pattern is consistent:
Souper Cubes at 18 months: Still performing like new. Silicone is flexible, lids still snap tight, no discoloration or odor retention. Users report treating them roughly — dishwasher cycles, hot soup directly from the stove, stacking in an overstuffed freezer — and they hold up.
Walfos at 18 months: Mixed reviews. About 60% of users are still happy. The other 40% report the silicone stiffening, lids not sealing as well, or cracks forming at the flex points. At the price point, most still feel they got their money's worth, but it's clearly not a long-term solution.
Which One Should You Buy?
The Bottom Line
For serious meal preppers: Get the Souper Cubes. They cost more upfront but deliver genuinely better materials (platinum-cured silicone), superior design (steel-reinforced rims, snap-on lids, fill lines, varied sizes), and significantly longer lifespan. At $0.30 per use over 5 years, they're actually a better value than they first appear.
For casual users and first-timers: Start with Walfos. At $25, it's a low-risk way to discover whether silicone freezer molds fit your kitchen routine. If you use them weekly for six months and wish they were better, you've validated the Souper Cubes upgrade. If they sit in a drawer, you're out $25 instead of $79.
Our pick: Souper Cubes. For anyone who actually meal preps with any regularity, the quality gap is worth the price. These things will outlast your current freezer.
