Best For Sides

OXO Good Grips 1.6 Cup Smart Seal Rectangle Container

Warping

You wouldn’t be able to fit a huge amount of roasted carrots or mashed potatoes in this container, but it's a good size for smaller quantities of sides, a portion of cheese and crackers, or that brownie you’d like to pack for dessert.

Materials: Borosilicate glass body, polypropylene lid, silicone gasket

Style: Glass

Oven Safe: To 450º F, preheated

Best For Small Amounts Of Salad Dressing Or Dips

OXO Good Grips 1 Cup Smart Seal Round Container

Performance

This is a tiny container, ideal for single-serving amounts of salad dressing, dips, or that bit of leftover avocado.

Materials: Borosilicate glass body, polypropylene lid, silicone gasket

Style: Glass

Oven Safe: To 450º F, preheated

Best In-Between Size

OXO Good Grips 2 Cup Smart Seal Round Container

Baking

This container isn’t large enough for a full-size meal or small enough for single servings of snacks. It would be useful for storing extra grains or beans or for that bit of leftovers you’re not quite sure what to do with. It’d also be good for a cup of soup to go along with a sandwich.

Materials: Borosilicate glass body, polypropylene lid, silicone gasket

Style: Glass

Oven Safe: To 450º F, preheated

Best For Leftovers And Storing Moderate Amounts Of Food

OXO Good Grips 3.5 Cup Smart Seal Rectangle Container

Broiling and Roasting

If you have a moderate portion of leftovers, this container is the perfect size. It’s also a great size for a sandwich and a few small sides, and is slim enough to slip easily into a bag or backpack. Of all the containers we tried, this size proved the most versatile.

Materials: Borosilicate glass body, polypropylene lid, silicone gasket

Winner

OXO Good Grips 4 Ounce Smart Seal Rectangle Container

Durability

This size is just a bit larger than the 1-cup size and rectangular instead of round. A handful of almonds or blueberries would fit perfectly in this container. It could also be useful for storing odds and ends of cheese in the fridge or that last bit of sauce you don’t want to waste.

Best For Soups And Most Lunches

OXO Good Grips 4 Cup Smart Seal Round Container

Durability

This round container is an excellent size and shape for packing up soup or grain bowls for lunch. It could also accommodate a small salad, but it’s not quite large enough for big servings of leafy greens.

Materials: Borosilicate glass body, polypropylene lid, silicone gasket

Style: Glass

Are Glass Containers Really Airtight?

To keep food at its freshest, you want a container that is airtight and leakproof. If it tips a little in a crowded refrigerator or while you're transferring it from one location to another, you want to be sure it won't spill. And if you happen to be storing very fragrant food, odors shouldn't escape the container. We found that the quality of the lid’s gasket makes the difference between a leakproof container and a potential spill.
