Rubbermaid Brilliance Container Set Best Overall

★★★★★ (4.8/5)
~$35 (10-piece set)

These are our go-to containers for storing prepped keto sides. The crystal-clear Tritan plastic doesn't stain (even with turmeric-heavy dishes), and the airtight lids keep food fresh for days. We've reheated countless portions of cauliflower mash and roasted vegetables without any warping.

The latching lids are 100% leak-proof—we've transported creamy coleslaw in a bag without a single drip. They stack beautifully in the fridge too.

What We Love

  • 100% leak-proof seal
  • Stain and odor resistant
  • Microwave/dishwasher safe
  • Stackable design
  • BPA-free Tritan plastic

Consider This

  • Higher price than basic containers
  • Lids take up storage space
  • Not oven-safe

Pyrex Simply Store Glass Containers Best Glass

★★★★★ (4.7/5)
~$30 (18-piece set)

Glass is ideal for reheating fatty keto dishes—no concerns about chemicals leaching, and glass won't absorb odors from garlic butter or cheese sauces. These Pyrex containers go from freezer to microwave to dishwasher without issue.

The various sizes are perfect for keto meal prep: small ones for dressings and sauces, medium for individual side portions, and large for batch-cooked vegetables.

What We Love

  • Non-porous glass
  • Freezer to microwave safe
  • No staining or odor retention
  • Variety of sizes
  • Oven safe (without lid)

Consider This

  • Heavier than plastic
  • Can break if dropped
  • Lids not leak-proof

Bentgo Prep 2-Compartment Containers Best Divided

★★★★☆ (4.5/5)
~$20 (10-pack)

When you want to keep your protein and sides separate (so roasted broccoli doesn't get soggy from meat juices), divided containers are the answer. These Bentgo containers have a secure divider that actually keeps foods apart.

Great for packing lunch with a main and a keto side, or for storing two different prepped vegetables in one container.

What We Love

  • True compartment separation
  • Perfect portion sizes
  • Leak-resistant lids
  • Great value (10-pack)
  • Microwave safe

Consider This

  • Not fully leak-proof
  • Fixed compartment sizes
  • Plastic only (no glass option)

Meal Prep Container Guide

Glass vs Plastic

Glass is better for high-fat foods and long-term storage—no staining or odor issues. Plastic is lighter for transport and won't break. For home meal prep, we suggest glass. For taking lunch to work, quality plastic like Rubbermaid Brilliance is more practical.

Sizes for Keto Sides

For individual side portions, 2-cup containers work perfectly. For batch-prepped vegetables, 4-6 cup sizes are ideal. Get a variety—you'll use them all.

Features That Matter

Leak-proof lids are essential if you're transporting food. Microwave-safe is a must for reheating. Look for BPA-free plastic or glass if you're concerned about chemicals.
