Yes, but we do not recommend microwaving your trays. However, if the steel rim is exposed at all, the trays will no longer be microwave safe. If you use your Souper Cubes in the microwave, they will no longer be covered by the warranty. Instead of microwaving your food in the Souper Cubes trays, we recommend popping out the frozen cubes and reheating them separately.
Yes, you can bake in your Souper Cubes. The trays are oven-safe up to 415F. The lids are not oven-safe.
We have never had any residual smells or odors even though we’ve been using the same tray for over two years to freeze foods with garlic, onions, tomatoes, ginger, cumin, and other spices/ingredients. We always recommend using a dishwasher to clean your Souper Cubes. If you do not have access to one, then clean with soap and hot water. Still have a slight smell in the trays? You can try a baking soda plus vinegar wash or baking your trays in a 350F oven for 30 minutes.
Souper Cubes trays are fairly stain-resistant. In fact, they have been tested by a third-party laboratory for stain resistance and passed. However, slight staining over a long period of use can happen and is not considered unusual. The best way to minimize or eliminate staining is by washing your Souper Cubes tray and lid in the dishwasher after each use.
If your trays do get stained, we recommend covering the stain in a 3% hydrogen peroxide solution for 24 hours. Cooks Illustrated has recommended this technique and has done testing that shows it is successful. https://www.cooksillustrated.com/how_tos/8614-removing-stains-from-silicone-spatulas

It is often believed that if you pinch silicone and it turns white, this proves that there are fillers in the silicone. However, US food-grade raw silicone is naturally white. The silicone used in Souper Cubes is FDA approved and undergoes extensive testing on a regular basis to ensure it exceeds food safety guidelines. Our products are tested quarterly to ensure that they meet the California Proposition 65 guidelines in addition to the FDA guidelines.
- Place your food directly in the Souper Cubes tray. You can place hot food in the tray. We recommend placing the lid on the tray once the food has cooled to minimize any condensation and trapped steam.
- Once the food has cooled, set it on a flat surface/shelf in the freezer. If you place warm or hot food in the freezer, it can potentially thaw adjacent foods. Allow up to 24 hours for the food to freeze depending on the temperature of your freezer and the food type.
- Once the food is frozen, remove it from the freezer and let it sit on the counter for 3-5 minutes. This allows the lid to warm up and expand making it easier to remove.
- To remove the frozen cubes from the tray, simply hold the rim and push up from the bottom of each cube. The cube should come right out pretty easily.
- Place up to eight cups’ worth of frozen food eight 1-cup cubes or four 2-cup cubes) into a gallon-size freezer bag. The bag should be just big enough to seal with all of the cubes inside.
- Label the bag with a permanent marker so you remember what you froze.
- Wash your Souper Cubes trays and lid, preferably in the dishwasher to get them ready for the next use.
You can freeze all types of food with your Souper Cubes! However, foods with moisture or a liquid base tend to freeze most easily. Most people use Souper Cubes to freeze foods like soups, stews, broth, and sauces. You can also freeze foods like rice, raw meat, shredded meat, chilis, and much more. Check out our recipes to get more ideas on what foods you can freeze with your Souper Cubes.
If you’re freezing hot foods, we do recommend that you let them cool before putting them in your freezer to avoid thawing your other frozen foods.
It depends on the content and the temperature of the food that you’re freezing. However, most foods can take up to 24 hours to freeze. Foods with high water content tend to take longer to freeze than foods like mashed potatoes or rice.
Food will become freezer burned when it is exposed to oxygen and loses its moisture. Souper Cubes lids are snug-fitting to prevent freezer burn as much as possible and you should not experience any freezer burn for 3-4 months. If you want to store your frozen food for a longer period, you can transfer your cubes into vacuum seal freezer bags. If your food becomes freezer burnt, it is still safe to eat. However, some of the flavors may be altered.
You can reheat Souper Cubes using the method that works best for you! We recommend popping the cubes out of the trays and reheating them with your stovetop, oven, or microwave. If you want to reduce the reheating time, you can let your cubes thaw on the counter or in the fridge before you heat them.
Leave your frozen tray on the counter for 3-5 minutes. This method will allow the lid to warm up and expand enough to make it easier to remove. If you’re in a rush, you can also run warm water over the lid.
Avoid trying to remove the lid when it is frozen because this can cause the plastic to break.
Most customers use the trays as a mold so they can reuse them to freeze other items. If you choose to leave the food in your Souper Cubes trays, we recommend using the food within 3-4 months to maximize the flavor of the dish.
