Don’t Have the Pan Called For? Use This Baking Dish Conversion Guide! (2024)

How to Convert Baking Dishes

• Be mindful of the baking time any time you do a dish swap.It may very well be a little shorter or longer than the recipe says. Converting to a smaller pan often means a longer bake time, while converting to a larger pan usually shrinks the cook time.
• Think of surface area. If two dishes have the same capacity but one is shallower, the shallower dish will probably bake faster than the deeper one.
• Glassware casseroles and dishes bake a little faster. Many sources call for reducing the oven temperature by 25°F if the recipe is baked in glassware. Even if you don’t reduce the oven temperature, you may want to check on the doneness a little earlier than normal.
• It’s better to use a larger dish than called for versus a smaller dish.No one wants an overflow situation—particularly if it means any spillover burning on the bottom of the oven. Don’t have a larger dish handy? Set your pan on a rimmed baking sheet as a precaution to catch any overflow.
• Doubling or halving recipes often will work, but you want to think of two factors: depth and surface area. Those will affect the baking time and consistency of your recipe.

• Every dish or pan is different. You’ll not get quite the same results baking brownies in glassware as you would aluminum. But don’t let that keep you from making brownies! Embrace the quirks of your baking dishes, and learn to make the most of them. Those little discoveries are what make cooking such a satisfying adventure.

Capacity Vs. Dimension

One issue is how baking dishes are classified. Sometimes manufacturers refer to how many quarts the dish holds, aka its capacity. These are often stoneware or glass casseroles, like Corningware, Pyrex, or Le Creuset.

And other dishes and pans—usually metal or glass ones—go by their dimensions. The classic 9x13-inch pan is a terrific example.

How to Measure a Dish or Pan

If you don’t know the dimensions or capacity of a baking dish, how can you know a recipe will fit in it? Don’t worry! There are a number of ways to find out.

• Look at the bottom of the pan or dish. Sometimes the capacity or dimensions are engraved or embossed there.
• Use a ruler or tape measure to measure it. Obvious, but there you go. That’ll give you the dimension. Measure the top of the dish from inner rim to inner rim.
• Measure the volume.Pour water from a measuring cup into a dish, filling it all the way to the top. This tells you its capacity.

• Use the dimensions to calculate the volume: Because most baking dishes are fluted on the sides, this method is imperfect, but it can give you a general idea of capacity. Measure the length, width, and height of the dish from its inside edges. Multiply those three numbers together and you’ll get the volume. For instance, an 11 1/2 x 7 3/4x2 3/4-inch dish has a capacity of 245 cubic inches. A 9x13x2-inch dish has a capacity of 234 cubic inches. Swapping one of those dishes for the other is likely a safe bet.
• Google it:Manufacturer’s websites may give you the capacity and dimensions of specific baking dishes on product pages. You could also try Amazon and look for product specs. This method does not work so well for the vintage Piral terracotta casserole you inherited from Aunt Margie, but it’s pretty solid for more common pans and dishes.
