Glass food storage containers do not stain, hold smells or warp, and most can go from fridge to microwave to dishwasher. They are ideal for slow cooker leftovers and meal prep. Here is how they compare to plastic and what to look for.
The Short Answer
Glass containers are worth it for leftovers and meal prep: they are non-porous, stain-resistant and usually microwave and dishwasher safe. Choose tempered or borosilicate glass, snap-lock lids with a silicone seal, and a mix of 2-cup and 4-cup sizes.
Glass vs Plastic
| Glass | Plastic | |
|---|---|---|
| Stains and smells | No | Yes, over time |
| Microwave | Yes (lid off or vented) | Only if labeled |
| Oven | Many bases (not lids) | No |
| Weight | Heavier | Light |
| Lifespan | Years | Shorter |
Safety Tips
- Avoid sudden temperature changes; let a frozen container thaw in the fridge before microwaving.
- Leave 1 inch of headspace when freezing soups and stews.
- Remove or vent plastic lids in the microwave.
- Do not use chipped or cracked glass.
Best Sizes
- 1 to 2 cups: single portions and sauces.
- 3 to 4 cups: meal prep and crockpot chili leftovers.
- 6 cups and up: family-size leftovers.
Glass Jars for the Pantry
For dry goods, glass jars keep pantry staples fresh and visible: the glass jar with wooden lid, the sealed glass jar with bamboo lid and spoon, and the clear glass jars with acacia lids. For bulk rice and cereal, a large airtight container works well.
Mixing and Serving in Glass
A 4.7 quart glass mixing and serving bowl goes from prep to microwave to table.
Equipment I Used
- Large airtight food storage container: for leftovers and freezer portions.
- 3-piece ceramic serving bowl set: takes food straight from the crock to the table.
