If you want divided glass meal prep containers that actually stay sealed, and specifically need 3 compartment glass meal prep containers, our pick is MCIRCO’s 3-compartment 36-oz set (5-pack). We looked for a leak-proof seal, an oven-safe glass base (lids off), and stackable pieces that are dishwasher-safe and easy to grab for the week’s lunches. As glass meal prep containers with lids, they stack cleanly and seal tightly.
🏆 Winner: MCIRCO 3-Compartment Glass Meal Prep Containers – 36 oz (5-Pack)
PF-Silicone: glass base + silicone gasket in the lid helps create the leak-proof seal. What’s our PF scale?
If you’re searching leak leak-proof glass meal prep containers, this set is reliable for dressings and sauces.
Why we like it: The borosilicate glass base handles fridge-to-oven transitions (with lids off) better than ordinary soda-lime glass. The snap-lock lid with silicone gasket keeps sauces where they belong, and the stackable design tucks neatly in the fridge so your Sunday prep doesn’t eat all your shelf space. Solid borosilicate-glass durability.
Size note: Also sold in 2-compartment and 30-oz/10-pack versions. Choose your set size on the product page.
