Both materials can work well, but they suit different needs.

• Silicone: Flexible sides make it easier to release frozen portions like soup, broth, sauces, or baby food. Many silicone trays are labeled dishwasher safe, and some note oven or microwave compatibility; always check the product details for temperature guidance.
• Plastic: Rigid trays hold their shape, stack neatly, and are popular for ice cubes and general freezer organization. Lids help prevent spills and limit freezer odors.

If you plan to portion larger foods, silicone can simplify removal. For tight stacking and traditional ice, plastic can be convenient. On Walmart.com, you can filter by material, capacity, and lid type to match your kitchen setup.

Portion size depends on how you reheat and serve.

• 1/2 cup: Handy for sauces, pesto, purees, or small add-ins.
• 1 cup: Great for individual servings of soup, chili, or oatmeal.
• 2 cups: Useful for hearty single meals or quick family add-ins.

Many trays are clearly labeled with capacity, and lids help stack portions neatly. When filling, leave a little headspace to allow liquid to expand as it freezes. If you vary your prep, consider a mix of sizes so you can freeze entrees and condiments separately. On Walmart.com, use filters for capacity and compartment size to find the best fit for your routine.

A few simple habits can keep your freezer tidy and minimize mess.

• Choose trays with lids: Flat, snap-on lids help stack securely and reduce odors.
• Don’t overfill: Leave headspace for expansion; this can reduce seepage as liquids freeze.
• Freeze flat first: Set trays on a level shelf or a baking sheet until solid, then stack.
• Use bins: A narrow freezer bin can corral trays in small freezers and RVs.
• Label and date: A piece of tape on the lid makes it easy to rotate meals.

Results can vary by freezer layout, so adjust shelf positions to keep trays level and easy to access.

Gentle release methods can help protect your trays and portions.

• For silicone: Let the tray sit at room temperature for a minute, then press from the bottom of each well. A quick rinse of the underside with lukewarm water may also loosen edges.
• For rigid plastic: Twist the tray slightly or tap the back; avoid sharp tools that could damage the mold.
• Batch storage: Once portions are out, transfer them to a labeled freezer bag or container to save space.

If sticking persists, a light coat of cooking-safe oil before filling may help, but check the product care instructions to keep your tray in good shape.

Regular cleaning helps trays last and reduces odors.

• Check care labels: Many trays note top-rack dishwasher compatibility; if not, hand-wash with warm water and mild dish soap.
• Rinse promptly: A quick rinse after emptying can keep stains from setting.
• Deodorize gently: For silicone, a soak in warm water with a little baking soda can help reduce lingering smells.
• Avoid abrasives: Skip harsh scrubbers or cleaners that could scratch or degrade the surface.
• Dry fully: Air-dry lids and trays before stacking to prevent moisture buildup.

Keeping lids on during storage may help limit freezer odors, but leaving trays open to air between uses can also be helpful.
