Glass Containers
Best for: People who microwave meals at work, anyone tired of stained/warped plastic, environmentally conscious cooks.
Pros
- No chemicals leaching into food, even when heated
- Do not absorb colors or smells (tomato sauce will not stain them)
- Go from freezer to microwave to table
- Last for years with proper care
- Clear sides let you see contents at a glance
Cons
- Heavier (a concern for packed lunches)
- Can break if dropped
- More expensive upfront
- Takes up more space due to rigid shape
What to look for: Borosilicate glass (more durable and temperature-resistant than soda-lime glass), snap-lock lids with silicone gaskets, and lids that are microwave-safe.
Plastic Containers (BPA-Free)
Best for: Budget-conscious cooks, families with kids, anyone who needs lightweight portable containers.
Pros
- Lightweight and inexpensive
- Shatterproof (great for kids' lunches and on-the-go meals)
- Wide variety of sizes and configurations
- Many options with compartments built in
Cons
- Stain easily (especially from tomato-based foods, turmeric, and beets)
- Absorb odors
- Can warp in the dishwasher or microwave
- Need to be replaced every 6-12 months
- Environmental concerns (even BPA-free plastics may have other chemicals)
What to look for: Polypropylene (#5 PP) is considered the safest plastic for food storage. Check the recycling number on the bottom. Avoid microwaving any plastic container unless specifically labeled microwave-safe.
Stainless Steel Containers
Best for: Plastic-free households, people who do not need to microwave, lunchboxes for school/work.
Pros
- Extremely durable and long-lasting
- No chemicals, staining, or odor absorption
- Eco-friendly and recyclable
- Look sleek and professional
Cons
- Cannot go in the microwave
- Not transparent (cannot see contents)
- More expensive
- Some lids do not seal as tightly (check reviews)
- Can dent
Choosing the Right Size
| Size | Capacity | Best For |
|---|---|---|
| Small | 1-1.5 cups (8-12 oz) | Snacks, sauces, dressings, sides |
| Medium | 2-3 cups (16-24 oz) | Lunch portions, single servings |
| Large | 4-6 cups (32-48 oz) | Full meals with sides, salads, family portions |
| Extra large | 8+ cups (64+ oz) | Batch cooking storage, soups, stews |
Features That Matter
- Leak-proof lids: The most important feature. Look for snap-lock lids with silicone gaskets. Test with water before trusting them in your bag.
- Compartments: Divided containers keep foods separate. Great for meals with wet and dry components (salad and dressing, rice and curry).
- Stackability: Containers that nest when empty and stack when full save space in both the cabinet and the fridge.
- Lid compatibility: Buying from one brand means lids are interchangeable and easier to match.
- Portion markers: Some containers have measurement lines on the side, helpful for portion control.
Recommended Starter Set
For someone beginning a meal prep routine for one or two people:
- 6-8 medium glass containers (for main lunch/dinner meals)
- 4 small containers (for snacks and sauces)
- 2-3 large containers (for batch cooking and salads)
- A set of freezer-safe containers or good freezer bags for make-ahead meals
Care Tips
- Wash lids by hand (dishwashers can warp them over time)
- Remove tomato stains from plastic by rubbing with baking soda paste, then leaving in the sun for an hour
- Do not microwave with the lid on (steam pressure can warp lids or cause splattering)
- Replace plastic containers when they become warped, cracked, or heavily stained
