What Are Souper Cubes?
Souper Cubes are silicone trays designed to freeze liquids into uniform, stackable cubes. Each cavity typically holds one cup (approximately 240 ml), and the trays come with a matching lid that snaps on securely. The silicone is food‑grade, BPA‑free, and marketed as freezer‑, microwave‑, and dishwasher‑safe. Because the cubes are pre‑portioned, they simplify meal planning: you can pop out a single cube of broth, sauce, or puree and add it directly to a recipe. The trays are also used for baking individual portions of batter, such as muffin‑size cornbread or mini quiches, which raises the question of oven compatibility.
Material Composition and Heat Resistance
The trays are made from platinum‑cured silicone, a high‑purity polymer that remains stable across a wide temperature range. Platinum curing eliminates the peroxide by‑products found in lower‑grade silicone, resulting in a material that does not off‑gas at elevated temperatures. The manufacturer rates the silicone for continuous use from ‑40 °F (‑40 °C) up to 450 °F (232 °C). This range comfortably covers most home oven settings, including typical baking temperatures of 350 °F to 425 °F. However, the lid is usually made from a different polymer (often a BPA‑free plastic) that is not rated for oven temperatures. Therefore, the tray itself can withstand oven heat, but the lid must be removed before any oven exposure.
Manufacturer Guidelines for Oven Use
Souper Cubes’ official documentation states that the silicone tray is oven safe up to 450 °F. The packaging and the brand’s website explicitly list “oven safe” as a feature, but they also caution that the lid is not oven safe and should never be placed in a heated oven. The guidelines recommend placing the tray on a baking sheet for stability, avoiding direct contact with heating elements, and not using the tray under a broiler. They also advise against sudden temperature shocks, such as moving a tray straight from the freezer into a preheated oven without a brief tempering period. Following these instructions ensures both safety and the longevity of the product.
Can Souper Cubes Go in the Oven? Direct Answer
Yes, the silicone tray portion of Souper Cubes can go in the oven. The tray is rated for temperatures up to 450 °F, making it suitable for most baking and reheating tasks. The critical caveat is that the accompanying lid is not oven safe and must be removed. Additionally, you should avoid broiler settings and direct flame contact. When used within these parameters, the trays perform reliably, allowing you to bake individual portions or reheat frozen cubes without transferring them to another dish.
Safe Temperature Limits
The safe operating window for the silicone tray is ‑40 °F to 450 °F. In practice, most home recipes call for oven temperatures between 300 °F and 425 °F, well within the limit. Exceeding 450 °F can cause the silicone to degrade, become brittle, or release trace compounds, so it is best to stay at least 25 °F below the maximum rating. If a recipe requires a higher temperature, consider transferring the contents to a conventional metal or glass baking dish.
How to Test Oven Safety at Home
Although the manufacturer provides clear ratings, some users prefer a personal verification before committing a full batch. A simple home test can give peace of mind.
- Preheat your oven to 350 °F (175 °C).
- Place an empty Souper Cubes tray on a rimmed baking sheet.
- Insert the tray and set a timer for 20 minutes.
- After the time elapses, carefully remove the tray using oven mitts.
- Inspect the silicone for any discoloration, warping, or unusual odor.
- If the tray appears unchanged and smells neutral, it has passed the test.
Repeat the test at 400 °F if you regularly bake at higher temperatures. Never test with the lid in place.
Step‑by‑Step Guide: Using Souper Cubes in the Oven
Follow these steps to safely bake or reheat food in Souper Cubes.
- Remove the lid. The plastic lid cannot tolerate oven heat and will melt or warp.
- Preheat the oven. Set the temperature according to your recipe, staying at or below 425 °F for a safety margin.
- Place the tray on a baking sheet. A rimmed sheet provides stability and catches any potential spills.
- Fill the cavities. Pour batter, soup, or other mixture into each cube, leaving a small headspace for expansion.
- Optional: Temper frozen cubes. If the cubes are frozen solid, let them sit at room temperature for 10‑15 minutes to reduce thermal shock.
- Insert into the oven. Position the baking sheet on the middle rack for even heat distribution.
- Monitor the bake. Check a few minutes before the recipe’s stated time; silicone conducts heat differently than metal.
- Remove carefully. Use oven mitts; the tray will be hot but flexible.
- Cool before handling. Allow the cubes to rest for a few minutes before popping them out.
- Clean promptly. Wash with warm, soapy water or place in the dishwasher (top rack) after cooling.

Best Practices for Oven Use
- Always place the tray on a sturdy baking sheet to prevent spills and provide rigidity.
- Keep the oven temperature at or below 425 °F for a comfortable safety margin.
- Never use the plastic lid in the oven; store it separately.
- Allow frozen cubes to temper briefly to avoid thermal shock.
- Use a timer and check a few minutes early; silicone can brown faster than metal.
- Rotate the baking sheet halfway through for even cooking.
- Let the tray cool on a wire rack before washing to prevent warping.
Common Mistakes to Avoid
- Leaving the lid on. The lid melts at relatively low temperatures and can release harmful fumes.
- Placing the tray directly on the oven rack. Without a baking sheet, the flexible silicone can sag, causing spills.
- Exceeding the 450 °F rating. High heat degrades silicone and shortens product life.
- Using under the broiler. Direct radiant heat can scorch the silicone instantly.
- Skipping the tempering step for frozen cubes. Rapid temperature change can cause cracking or uneven heating.
- Cleaning with abrasive pads. Scratches create niches for bacteria and reduce non‑stick performance.
Cleaning and Maintenance After Oven Use
After baking, allow the tray to cool completely. Wash with warm, soapy water using a soft sponge. The tray is dishwasher safe on the top rack, but hand washing extends its lifespan. Avoid harsh chemicals, bleach, or abrasive scrubbers. Inspect the silicone periodically for signs of wear such as cracks, stickiness, or persistent odors. If any damage appears, retire the tray from oven use; it can still serve for freezer storage. Store the tray flat or nested with the lid off to prevent deformation.
