Ingredient Notes

Here are some of the ingredients you will need for the Apple French Toast Casserole:

  • apples – slice them into very thin slices so they cook easily. I like using honey crisp apples or other baking apples for this. They can be peeled or unpeeled.
  • French bread – dryer, stale bread works better as they will soak up the egg mixture better. You can also use sourdough, challah, regular white bread, or even healthier breads such as whole wheat. I typically prefer bread with a touch of sweetness for my french toast bake.
  • eggs
  • milk – 2% or more will make your French Toast Casserole creamier, but you can also use lower fat or even milk substitute such as oat milk and almond milk
  • vanilla extract – pure vanilla extract gives it the best flavor!
  • brown sugar
  • powdered sugar – used as the dusting on the top of the French toast bake.
  • maple syrup – highly recommend 100% pure maple syrup for the best taste.

We are going to top our apple French toast casserole with a streusel topping that is to die for. It’s seriously a must so don not skip this step if you want the ultimate gastronomical experience.

Here’s what you will need for the streusel topping:

  • brown sugar
  • all purpose flour
  • ground cinnamon
  • unsalted butter

How to Make Apple French Toast Casserole

Brunch is one of my favorite things about the weekends. I love to slowly get up in the morning, enjoy the relaxing pace of the weekend, and savor the meal that is breakfast and brunch.

When brunch can be made ahead of time, life is even better.

I typically make Apple French Toast Casserole the night before, let it sit overnight, and then bake it in the morning. This way you can wake up, and pretty much have breakfast close to being ready. Trust me, it’s the best feeling.

If you are really press for time, and wanted Apple French Toast Casserole at the last minute, then go ahead and skip the soaking step. It’s not the best way to make it but it’s still totally edible and will still be yummy.

Don’t forget to drizzle with maple syrup!

Step 1: Bring together casserole

The first thing I do when I make Apple French Toast Casserole is to whisk together eggs, milk, vanilla extract, ground cinnamon, and brown sugar in a large mixing bowl.

I then prepare a 9″x13″ casserole by greasing it with cooking oil spray.

Spread half the cubed French bread to casserole dish, add half of the sliced apples, then pour half of the egg mixture.

Add the rest of the French bread, then add the rest of the sliced apples, then the rest of the egg mixture.

Step 2: Let it rest

Cover and store Apple French Toast Casserole overnight or for a couple of hours in the refrigerator. This will let the egg mixture soaks into the bread thus making it moist and flavorful.

Make the crumb topping separately by combining all the ingredients in a bowl.

Let the crumble sit in the refrigerator overnight too, but do not add it to the Apple French Toast Casserole until you are ready to bake it.

Right before french toast casserole is ready to be sent into the oven, spread the top with crumble. This is going to give you apple french toast casserole an additional dimension of sweetness and texture.

Frankly, it is also one of my favorite parts of this recipe.

Step 3: Bake

After sprinkling Apple French Toast Casserole with that brown sugar crumble topping before baking, bake in the oven for 40-45 minutes at 350℉.

When it is done, your french toast bake will crusty on the edges and soft on the insides.

If the insides are still watery, go ahead and cook it for slightly longer.

When done, sprinkle some powdered sugar on Apple French Toast Bake for that “snow top” look, and serve it with maple syrup because you know you love that maple syrup! 🙂

  • Use dry, a-few-day-old bread so that egg mixture can soak into the bread more effectively.
  • Remember to grease casserole dish before adding items to it to french toast from sticking to it
  • Use Honey Crispy apples or other “baking-friendly” apples for this recipe.
  • Slice the apples thinly so that it cooks well in the oven.

Keep apple French toast casserole the refrigerator in an airtight container for a few days. Store maple syrup separately. When ready to serve, heat in microwave and serve with maple syrup.

You can also freeze it in an airtight container for up to 1 month. When ready to eat, bring it to a complete defrost before reheating in the microwave.

Frequently Asked Questions

You can if you are press for time. It’s not ideal but it’s still edible and tasty! We let it sit so that the dry bread can soak up the egg mixture.

Peel apple and slice into very thin slices. If you want it to be super soft, you can saute them in a skillet beforehand.
