An 8x8x2-inch square pan is the most common 2 quart baking dish. It holds 8 cups, or about 1.9 liters, filled to the brim. An 11×7 glass oblong dish and a 9-inch round dish about 2 inches deep land in the same range. A 9×13 pan is bigger, usually around 3 quarts.
2 quart baking dish sizes at a glance
Two US quarts equal 8 cups, 64 fluid ounces, or about 1.9 liters. Any dish that holds that much water to the brim is a 2-quart dish, whatever its shape. These are the common sizes, with approximate capacities. Brands differ slightly, so treat the numbers as a guide.
| Dish | Approx. capacity | Surface area | 2-qt match? |
|---|---|---|---|
| 8x8x2 in square | 8 cups / 2 qt | 64 sq in | Yes |
| 11x7x2 in oblong | 8 cups / 2 qt | about 77 sq in | Yes |
| 9 in round, 2 in deep | about 8 cups / 2 qt | about 64 sq in | Yes |
| 8x8x1.5 in square | about 6 cups / 1.4 L | 64 sq in | No, about 1.5 qt |
| 9x9x2 in square | about 10 cups / 2.5 qt | 81 sq in | Close, a bit larger |
| 9x13x2 in rectangle | about 3 qt (12 to 15 cups) | 117 sq in | No |
If your dish has a quart number stamped on the bottom, trust that over any dimension you read online.
Is an 8×8 pan 2 quarts?
Yes, as long as it is 2 inches deep. A standard 8x8x2-inch square pan holds about 8 cups, which is exactly 2 quarts. That is why many recipes for brownies, cornbread and small casseroles are written for it.
The catch is depth. Many metal 8×8 pans are only 1.5 inches deep, and those hold closer to 6 cups, or roughly 1.4 liters. That is about a quart and a half. Two pans can both say “8×8” and differ by a full 2 cups.
Check the depth before you trust the name
Lay a ruler inside the pan from the bottom to the rim. A 2-inch reading means you most likely have a true 2-quart pan. A 1.5-inch reading means you do not.
Round and oblong 2 quart baking dish options
Round dishes. A common 2-quart round casserole is about 9 inches across and 2 inches deep. Some makers shape theirs 8 inches across and closer to 3 inches deep, which gives the same volume in a narrower, taller dish. Both are sold as 2-quart. A 9-inch round cake pan that is only 1.5 inches deep holds less.
Oblong dishes. The Pyrex 2 Quart Glass Oblong Baking Dish measures about 11.1 x 7.1 inches, based on retailer listings. Those are outside dimensions, handles included. The inside measures a bit less. It is often called an 11×7, and it is a handy size for lasagna for two to four people, a small enchilada casserole or a fruit crisp.
Is a 9-inch round the same as an 8×8 square? Nearly. A 9-inch round has about 64 square inches of surface, the same as an 8×8 square. If both are 2 inches deep, the volumes are close enough to swap in most recipes. Round pans cook the edges slightly faster because there are no corners, so check a few minutes early.
Why a 9×13 pan is not a 2 quart baking dish
A 9×13 is usually sold as a 3-quart dish. Estimates run from about 2.4 to 3.5 quarts, depending on wall thickness and slope. Pyrex labels its 9×13 as 3 quarts. Deeper ceramic 9×13 dishes can reach 4 to 5 quarts.
That makes a 9×13 roughly 50% larger than a 2-quart dish. Surface area is the bigger difference: 117 square inches against 64 for an 8×8. Food spread in a 9×13 will be thinner, so it cooks faster and browns more.
Worked example
A recipe calls for a 2-quart dish and about 6 cups of filling. In an 8x8x2 pan, that fills the pan to roughly an inch below the rim, which is right. In a 9×13, the same filling makes a layer under an inch thick. It will be done in perhaps two-thirds of the time and may dry out. Either halve the recipe for the 9×13 or keep the full recipe and use a smaller dish.
How to measure a baking dish with water
When there is no label, the water test settles it in about two minutes. It works for glass, ceramic and metal.
- Set the dish on a level counter.
- Fill a 4-cup liquid measuring cup with water.
- Pour it into the dish, counting each cup, until the water is level with the rim.
- Divide the total cups by 4 to get quarts. Eight cups is 2 quarts.
Many dishes have a rim, a lip or sloped sides, so the true brim fill can be a little different from the printed size. The same goes for dimensions: some brands measure inside edge to inside edge, others measure outside rim to outside rim, handles included. That is why a dish labeled 8 inches can measure 8.5 or 9 inches with a tape. The water test skips the guesswork.
Leave headroom
A dish filled to the brim is not a dish you can safely bake in. For saucy or bubbling recipes, plan to fill to about an inch below the rim. In a 2-quart dish, that means roughly 6 to 7 cups of food. If your recipe makes more, step up to a larger dish rather than packing it in.
What to use instead of a 2-quart casserole dish
Match the volume first, then the surface area. These swaps work for most casseroles, bars and baked pastas.
- 9x9x2 square (about 2.5 qt): Works for a 2-quart recipe, especially if the recipe fills the dish well. The food will be a bit thinner, so start checking 5 minutes early.
- Two 1-quart dishes: Same total volume, shorter bake. Check at about two-thirds of the time.
- 9×13 with a half batch: Cut the recipe in half and bake in the larger dish. Expect shorter cooking.
- Ovenproof skillet or Dutch oven: Fine for stews, baked pasta and cobblers when the volume is right.
If you shop for a replacement, look at what the dish is made of. Our guides to stainless steel baking pans and non-toxic baking pans cover metal options that fit these sizes.
Adjust bake time and avoid cracked dishes
The pan material changes the bake as much as the size does.
- Glass and ceramic heat slowly and hold heat. Many recipes tested in metal suggest lowering the oven by 25°F when you use glass. Check the recipe notes first.
- Metal heats and browns faster, especially dark-coated pans.
- Shallower or wider dish: shorter bake, so start checking at about 75% of the stated time.
- Deeper or narrower dish: longer bake, and the center may lag behind the edges.
Judge doneness by what the recipe says: a set center, golden top, bubbling edges or a food thermometer reading. Casseroles with meat or eggs need to reach safe internal temperatures, so do not go by color alone. Poultry must hit 165°F.
Glass and ceramic safety
- Do not move a dish from the freezer straight into a hot oven. Let it sit on the counter first, unless the maker says it is freezer-to-oven safe.
- Do not set a hot dish on a wet or cold surface. Use a dry towel or trivet.
- Do not pour cold liquid into a hot dish.
- Check the maximum temperature on the box or maker’s site. Ratings vary by model.
- Use dry oven mitts. A damp mitt can transfer heat fast and cause a burn.
Sudden temperature changes can crack or shatter glass and ceramic. Chipped or cracked dishes are more likely to fail, so retire them.

Frequently Asked Questions
How many cups are in a 2 quart baking dish?
A 2-quart dish holds 8 cups when filled to the brim. For baking, fill it to about an inch below the rim, which is roughly 6 to 7 cups of food. That leaves room for bubbling and rising.
Can I use a 9×13 pan for a 2-quart recipe?
You can, but the food will spread thin and cook faster. Halve the recipe for the best result, or check for doneness at about two-thirds of the stated time. A 9×13 typically holds around 3 quarts.
Is a 9×9 pan the same as a 2 quart dish?
Not exactly. A 9x9x2 pan holds about 10 cups, or 2.5 quarts, so it is a bit larger. It works as a substitute for many 2-quart recipes. Start checking for doneness about 5 minutes early.
Does a 1.5-inch-deep pan hold 2 quarts?
No. An 8×8 pan that is 1.5 inches deep holds about 6 cups, or roughly 1.4 liters. That is closer to a quart and a half. Measure depth from the inside bottom to the rim, or use the water test.
