How much does a 9×13 casserole dish hold?

A 9×13 casserole dish is a very common baking dish size used for making hearty casserole recipes that feed a crowd. But exactly how much food can you fit in a 9×13 casserole pan? Here we’ll take a look at the capacity of a standard 9×13 casserole dish, how that translates to cups of liquid or food, and how much food you can expect a 9×13 casserole recipe to yield.

Dimensions of a 9×13 Casserole Dish

A standard 9×13 casserole baking dish measures 9 inches wide by 13 inches long. The depth of a typical 9×13 casserole pan is around 2.5 inches.

So the interior dimensions of a 9×13 casserole dish are:

  • Width: 9 inches
  • Length: 13 inches
  • Depth: 2.5 inches

Volume and Capacity of a 9×13 Casserole Dish

Using those interior dimension measurements of a 9×13 casserole pan, we can calculate the total volume and capacity.

To find the volume, we use the formula:

Volume = Width x Length x Height

Plugging in the dimensions of a 9×13 pan:

Volume = 9 inches x 13 inches x 2.5 inches
= 292.5 cubic inches

Now to calculate the liquid capacity, we convert that volume to cups:

1 cup = 14.4375 cubic inches

292.5 cubic inches ÷ 14.4375 cubic inches per cup = 20.25 cups

So a standard 9×13 casserole dish holds about 20.25 cups of liquid.

Yield of Food in a 9×13 Pan

When making casserole recipes in a 9×13 dish, you won’t actually be able to fit 20.25 cups of food in the pan. Food takes up more space than pure liquid.

As a general rule of thumb, you can expect a 9×13 casserole dish to hold:

  • 12 – 15 cups of cooked grains or noodles
  • 10 – 12 cups chopped or diced vegetables
  • 8 – 12 cups of shredded meat or protein

So you can comfortably fit around 10-15 cups of most casserole ingredients into a 9×13 baking dish depending on the density of the ingredients.

Typical Yields for 9×13 Casserole Recipes

Based on the capacity of a 9×13 pan, here is how much a typical 9×13 casserole recipe will yield:

  • 12 – 24 servings for sides or vegetables
  • 8 – 12 servings for main dish casseroles
  • 24 – 36 servings for dessert bars

The exact yield will depend on the recipe itself and how large you cut each portion. But in general, a 9×13 casserole dish can feed anywhere from 8 to 36 people depending on the recipe.

Common Uses for a 9×13 Casserole Dish

Some of the most common uses for a 9×13 baking pan include:

  • Baking casserole recipes
  • Making lasagna or baked pasta
  • Baking meatloaf
  • Roasting vegetables
  • Making sheet pan dinners
  • Baking dessert bars and brownies

A 9×13 casserole dish is also handy for re-heating leftovers. You can reheat individual portions on a plate or bake the whole pan of leftovers to serve a crowd.

Tips for Baking in a 9×13 Pan

Here are some tips to ensure your recipes turn out perfectly when baking in a 9×13 casserole pan:

  • Grease the pan – Coat the inside of the dish with butter, oil, or non-stick cooking spray before adding your batter or food. This prevents sticking.
  • Use middle rack position – Place the 9×13 pan in the center of your oven for optimal heat circulation.
  • Follow recipe baking times – Recipes designed for a 9×13 pan will have the proper baking time. Check for doneness early.
  • Let it rest before serving – Allow casseroles, dessert bars, etc. to cool and set up at least 15 minutes before cutting.
  • Avoid overcrowding – Don’t overfill the pan with too much food or batter to prevent boil overs.

9×13 Casserole Dish Options

9×13 casserole pans are available in various materials including:

  • Glass – Heats evenly and allows you to monitor browning on the bottom. But may break if dropped.
  • Metal – Such as aluminum or stainless steel. Affordable but may warp over time.
  • Ceramic – Attractive option that provides even heating. But heavier than other materials.
  • Stoneware – Excellent heat retention and very durable. But requires extra care not to crack it.

Glass and metal 9×13 pans are the most common. Glass lets you keep an eye on the bottom but can break. Metal is lightweight but may discolor or warp.

Other Pan Sizes Similar to 9×13

In addition to the standard 9×13 size, some other casserole pans comparable to a 9×13 include:

Pan Size Dimensions Capacity
8×12 8″ x 12″ x 2″ 12-15 cups
8×8 8″ x 8″ x 2″ 6 cups
9×9 9″ x 9″ x 2″ 10 cups

The 8×12 size is very close to a 9×13 and can be used the same way. The 8×8 and 9×9 sizes are good for smaller batches.
