Why You’ll Love This Recipe

French toast casserole is everything you love about french toast, in a creamy, delicious casserole format. It’s still best topped with syrup, powdered sugar, or fresh fruit, but I think it takes way less work than traditional french toast!

The air fryer does a great job of getting browned edges and a creamy, perfect interior. It’s easy to portion size it for 2 or a crowd, and it cooks up in less time than the oven as well.

I just put everything together the night before and pop it in to air fry in the morning. It’s perfect for low stress holidays, Mother’s Day, or fancy brunches. You can even make it on a weekday morning and let it cook while you get ready!

Ingredients to Grab

easy air fryer casserole ingredients
  • 8 slices of cinnamon swirl brioche bread (slightly stale is best)
  • 4 large eggs
  • ½ cup milk or half and half
  • 1 tsp cinnamon
  • 1 tsp vanilla extract
  • ¼ tsp salt

Ingredient Tips and Variations

  • If you don’t use a brioche bread, sprinkle a cubed Tbsp of butter over the casserole before cooking
  • You can also use other types of bread, such as Challah, French bread, chocolate or vanilla brioche, other cinnamon or raisin bread, or even cubed up cinnamon rolls
  • For a creamier casserole, swap half of the milk for heavy cream
  • The amount of seasoning may be adjusted to taste. Feel free to add other spices such as nutmeg, pumpkin pie spice, or apple pie spice in as well
  • Variations: Add ¼ cup of raisins, chopped nuts, or fresh fruit and about 4 Tbsp cubed cream cheese in for a different twist

Special equipment note: You’ll need an oven-safe pan that fits in your air fryer basket or rack for this recipe. A cake pan, casserole dish, springform pan, or similar should do the trick. I’m using two small rectangular casserole dishes because I have a Ninja Foodi dual zone air fryer with two compartments. However, in most other cases, one single dish is sufficient.

Recipe FAQs

Why is My French Toast Casserole Soggy?

Your french toast casserole is soggy if there is too much liquid or the bread is too soft to start.

The recipe is best made using day-old or stale bread, which absorbs the custard better. Make sure to let the bread sit and soak up the liquid so it’s not pooled in the bottom of the pan.

How Do You Reheat French Toast Casserole in an Air Fryer?

Reheat french toast casserole in an air fryer for 3-5 minutes at 350°F. The exact time will depend on the size of your piece and your specific air fryer.

If it has previously had syrup added, use a piece of parchment or foil under it to keep the air fryer from becoming sticky.

Can I Use Stale Bread or Fresh Bread for the Casserole?

Stale or slightly dried out bread is ideal for this casserole because it absorbs the egg mixture without becoming overly soggy.

However, if you don’t have stale bread, you can use fresh bread and let it sit out for a while to dry. Alternatively, you may lightly toast your bread cubes in the oven or air fryer to draw out some moisture.

What Kind of Bread Works Best for Air Fryer French Toast Casserole?

Bread with a sturdy texture, like brioche, challah, or French bread, works best for this casserole.

These bread types hold up well to the egg mixture and air frying process.

How Long Does it Take to Cook French Toast Casserole in the Air Fryer?

Typically, it takes around 15-20 minutes at 350°F (175°C) to achieve a golden and crispy texture.

Cooking times can vary depending on your air fryer model, type of bread used, and the size of your casserole dish.

What Ingredients Can I Add to Customize My Casserole?

You can customize your casserole with ingredients like cinnamon, nutmeg, vanilla extract, fresh fruit, chocolate chips, or nuts to suit your taste preferences.

For a savory alternative, use a non-sweet bread, omit the vanilla and cinnamon, and instead add ingredients like cheese, bacon, or vegetables for a savory breakfast or brunch dish.

Can I Make Air Fryer French Toast Casserole in Advance?

Yes, you can prepare the casserole the night before, cover it, and refrigerate it. In the morning, simply air fry as indicated. This cuts down on preparation time, which is ideal when entertaining.

Alternatively, you may also cook the casserole completely ahead of time, and then just reheat individual portions for a few minutes before serving.

Recipe Pro Tips

  • You do not need to flip or stir your casserole during the air frying process. If it begins to get too brown on top, cover the baking dish with a piece of foil
  • A dark brown, slightly crusty top is normal, with a soft, custard like texture underneath (similar to a bread pudding)
  • The pan will be hot when you remove it from the air fryer, just like an oven would, so use caution (and oven mitts)!

Storage and Reheating Tips

  • Store leftover french toast bake wrapped in the refrigerator for up to 3 days
  • To reheat french toast casserole, place a portion in the air fryer (I recommend placing it on a piece of foil or parchment unless it’s still in the baking dish). Air fry at 350°F for 3-5 minutes, until warmed through and re-crisped on top. Exact time will vary based on the size of your piece
