What is the best meal prep container that does not leak?

Best overall: Rubbermaid Brilliance Food Storage Containers. They’re a strong default for meal prep if leak resistance is your top priority, especially for packed lunches, sauces, and liquids, because the lids lock on securely and the containers stack well.

If you frequently reheat meals, consider the glass version of Rubbermaid Brilliance or another glass option such as Pyrex Freshlock, since glass is generally better for repeated microwaving than plastic.

No container stays leakproof under every condition. To reduce leaks, make sure the lid is fully seated and locked, avoid overfilling, and replace containers or lids if the seal becomes dirty, damaged, warped, or loose. Thin liquids like soup or watery sauces are the best test of leak resistance and are also the most likely to expose a weak seal.
