Souper Cubes Review: Are These Silicone Freezer Trays Worth It?
Have you ever cooked a big batch of soup or sauce and struggled with freezing the leftovers in leaking freezer bags or bulky containers? That was me for years until I discovered Souper Cubes. I bought my first set years ago, and they quickly became one of the most used tools in my kitchen for freezing soups, broths, sauces, and leftovers into perfect portions.

This review is not sponsored. I purchased my Souper Cubes myself and have used them consistently for over seven years. I only recommend products I genuinely use in my own home, and these have earned a permanent place in my freezer routine.

What Are Souper Cubes?

Souper Cubes are reusable silicone freezer trays designed to freeze food into recipe-size portions and individual portions instead of awkward plastic containers or oversized glass food storage containers. They were created by Michelle and Jake, who wanted a better way for home cooks to freeze leftovers without waste. What started as a small idea became a practical solution for freezer meal prep and better portion control.

The trays are made from thick, high-quality silicone with an embedded steel rim that keeps them sturdy even when filled with hot soups or heavier foods. The clear plastic lids fit snugly and help prevent spills while stacking. Clear measurement markings and fill lines make portioning easy, whether you are freezing tablespoon amounts or full two-cup portions.

Key features include:
• 100 percent FDA food-grade silicone
• BPA-free materials
• Clearly marked fill lines for accurate portions
• Dishwasher-safe trays and lids
• Oven-safe silicone trays up to 415 degrees with lids removed

Why I Love Souper Cubes

I hate wasting food, and Souper Cubes completely changed how I handle leftovers. When cooking in the Instant Pot or making big batches of soup like chicken soup or homemade chicken broth, I am often left with more food than my family can eat in a few days. Freezing perfect portions makes storing, reheating, and using leftovers simple while helping prevent freezer burn and saving money on our food bill. I also appreciate that Souper Cubes is a small, family-owned business that gained national attention after appearing on Shark Tank, which makes supporting the brand feel even better, knowing it was created by people who actually understand home cooking and food waste.

Here is how I use each size:
• One-cup trays for soups, bone broth, chili, yogurt, smoothies, and individual meals
• Two-cup trays for pasta dishes, pasta sauce, rice, casseroles, freezer meals, enchiladas, and large portions
• Half-cup trays for pesto, hummus, applesauce, grains, mashed potatoes, and medium-sized ingredients
• Tablespoon trays for leftover tomato paste, herb purées, hatch chiles, baby food, individual spices in oil, minced garlic, and small amounts of sauces
• Cookie trays for freezing cookie dough, brownie bites, muffin batter, and other small batters using a #40 cookie scoop
• MyMylk trays for breast milk, homemade nut milks, kefir cubes, and other liquid dairy-free milks
• Trays for herbed butter or compound butters — perfect for topping steaks, corn, or bread with flavor straight from the freezer
• Portion trays for rendered tallow, lard, or duck fat so you can freeze cooking fats in usable spoonfuls
• Trays for freezing baby purees, fruit purée pops, or smoothie boosters like spinach-banana cubes
• Bundles and Gift Sets that include multiple tray sizes with reusable lids for flexible freezer meal prep
• Ceramic baking dishes that fit perfectly with frozen cubes for baking or reheating meals from frozen
• Optional accessories like labeling tape and markers to organize your freezer stash

How to Use Souper Cubes

Using Souper Cubes is very simple. Spoon or ladle food into the tray up to the fill lines, wipe the rim clean, and secure the lid. If you are working with hot soups or liquids, letting them cool slightly before filling helps prevent condensation under the lid. For easier transport to the freezer, especially when filling multiple trays at once, I like to place the trays on a baking sheet so they stay level and do not spill. This is especially helpful when filling several trays during batch cooking.
Place the trays flat in the freezer where they stack neatly and save freezer space. Using more than one tray lets you freeze large batches efficiently without waiting for a single tray to empty. Once frozen, usually within 24 hours, remove the tray and gently press from the bottom to release the frozen cubes. I prefer doing this over a bowl or cutting board in case a cube slips out.

How to Store Souper Cubes Once Frozen

Once the cubes are fully frozen, I remove them from the trays and transfer them into labeled freezer bags or reusable freezer-safe storage to free up the trays for the next batch. Storing cubes this way saves freezer space and makes it easy to see what you have on hand. For short-term storage, standard freezer bags work well as long as excess air is pressed out. To prolong freezer life and reduce freezer burn, using a vacuum sealer is the best option, especially for soups, broths, sauces, and freezer meals you plan to store longer. I label each bag with the contents and date, so rotating through my freezer stash stays simple and nothing gets forgotten in the back of the freezer.

Souper Cubes Compared to Other Freezer Storage Options

Before using Souper Cubes, I relied on plastic freezer bags, glass containers, and basic silicone trays. Each option had drawbacks. Freezer bags are inexpensive but hard to portion evenly, prone to leaks, and often lead to freezer burn. Glass containers take up too much freezer space and are not practical for freezing small portions. Many silicone trays lack durability or measurement markings.
Souper Cubes stand out because they freeze food into uniform portions first, stack efficiently, include clear fill lines, and are sturdy enough for long-term use.

Are Souper Cubes Worth It?

After using Souper Cubes weekly for over 7 years, I can confidently say they are worth the investment. While the upfront cost is higher than disposable options, the long-term savings from reduced food waste, better portion control, and efficient freezer storage make them well worth it.

Pros
• Multiple portion sizes for flexibility
• Efficient stacking and organized freezer storage
• Easy to clean
• Helps reduce food waste
• Makes meal planning from the freezer easier
• Great for grab-and-go meals
• Allows different meals for different family members

Cons
• Once you buy one set, you will want more
• They do not go on sale often
• Initial investment cost

How Long Does Food Stay Good in the Freezer?

Storage time depends on how the cubes are stored. When using standard freezer bags, frozen cubes are best used within three to four weeks to minimize freezer burn. Vacuum-sealed storage can extend the lifespan of food up to six months. Storing cubes directly in the trays works but limits tray availability. Resealable vacuum bags from ForJars offer the best balance of freshness and convenience.

How to Clean Trays and Lids

I was initially concerned that silicone trays might hold odors or stains, especially with tomato-based sauces. After years of use, I have not experienced staining or residual smells. I usually hand-wash the trays with warm water and dish soap, but both trays and plastic lids are dishwasher safe.

How to Reheat Frozen Cubes

Most frozen cubes do not need to be defrosted before reheating. One-cup portions of soups and chili reheat well in the microwave in about four to five minutes, especially when covered. For larger portions or multiple cubes, reheating on the stovetop with a lid works best. Lasagna or enchiladas can be reheated or baked using two-cup ceramic baking dishes. The silicone trays are oven safe up to 415 degrees, you can also prep, freeze, and bake directly in them.
