Ingredients You’ll Need

You only need a handful of familiar ingredients to make this comforting breakfast casserole.

Bread

Thick, slightly stale bread works best because it absorbs the custard without becoming too soft. Brioche and challah are excellent choices. French bread also works well.

Apples

Choose apples that hold their shape during baking. Granny Smith provides a tart contrast, while Honeycrisp, Pink Lady, and Braeburn offer a sweeter flavor.

Cinnamon

Ground cinnamon gives both the apples and the custard their warm fall flavor. A small amount of nutmeg adds extra depth.

Eggs and Milk

Eggs, whole milk, and heavy cream create the rich custard that soaks into the bread.

Brown Sugar

Brown sugar adds sweetness and a subtle caramel flavor that pairs naturally with apples and cinnamon.

What Is the Best Bread for French Toast Casserole?

Brioche is one of the best choices because it is rich and tender. Challah is another excellent option. However, a sturdy French loaf can also produce great results.

Whichever bread you choose, slightly stale bread is ideal. Fresh bread contains more moisture and can become overly soft after absorbing the custard.

If your bread is very fresh, cut it into cubes and let the pieces sit uncovered for a few hours before assembling the casserole.

How to Make Apple Cinnamon French Toast Casserole

Prepare the Baking Dish

Lightly grease a 9×13-inch baking dish. Then spread the bread cubes evenly inside the dish.

Cook the Cinnamon Apples

Melt butter in a skillet over medium heat. Add the diced apples, brown sugar, cinnamon, and a pinch of salt.

Cook briefly until the apples begin to soften. They do not need to become completely tender because they will continue cooking in the oven.

Make the Custard

Whisk the eggs, milk, heavy cream, brown sugar, vanilla, cinnamon, nutmeg, and salt in a large bowl.

Continue whisking until the mixture is smooth and evenly combined.

Assemble the Casserole

Spoon the cinnamon apples over the bread. Gently toss or distribute them so that apple pieces are spread throughout the casserole.

Next, slowly pour the custard over the bread. Press the bread down gently so the cubes begin absorbing the liquid.

Add the Brown Sugar Topping

Combine brown sugar, flour, cinnamon, and softened butter. Mix until coarse crumbs form.

Sprinkle the mixture evenly over the casserole.

Chill Before Baking

Cover the baking dish and refrigerate it for at least 30 minutes. For an easy make-ahead breakfast, refrigerate the assembled casserole overnight.

The resting time allows the bread to absorb the cinnamon custard.

Bake Until Golden

Preheat the oven to 350°F (175°C).

Bake the casserole uncovered until the center is set and the top is golden brown, about 40 to 50 minutes.

If you prefer a softer casserole, bake closer to the lower end of the range. For a firmer and more golden top, give it a few additional minutes.

Can You Make It the Night Before?

Yes. In fact, this is one of the easiest ways to serve this recipe.

Assemble the casserole, cover the baking dish, and refrigerate it overnight. The next morning, remove it from the refrigerator while the oven preheats.

Then bake as directed. A very cold casserole may need a few additional minutes in the oven.

Best Apples for French Toast Casserole

Firm apples are the best choice because they keep some texture after baking.

• Granny Smith: tart and firm.
• Honeycrisp: crisp with balanced sweetness.
• Pink Lady: sweet-tart and aromatic.
• Braeburn: firm with a warm apple flavor.

You can also combine a tart apple with a sweeter variety for more balanced flavor.

Tips for the Best Apple French Toast Casserole

• Use thick bread rather than thin sandwich bread.
• Allow fresh bread to dry slightly before using it.
• Cut the bread into similar-sized cubes for even baking.
• Do not fully cook the apples in the skillet.
• Give the bread enough time to absorb the custard.
• Let the baked casserole rest briefly before serving.

What to Serve With It

This casserole is delicious on its own, but a few simple toppings can make it even better.

Try it with warm maple syrup, a light dusting of confectioners’ sugar, chopped pecans, fresh apple slices, or a spoonful of Greek yogurt.

For a larger brunch, serve it alongside fresh fruit or eggs.

How to Store Leftovers

Allow leftovers to cool, then store them in an airtight container in the refrigerator for up to 3 days.

Individual portions can be reheated in the microwave. For a slightly crisper top, warm them in the oven instead.

Can You Freeze French Toast Casserole?

Yes. Once baked and completely cooled, divide the casserole into portions and store them in freezer-safe containers.

For the best texture, thaw a portion overnight in the refrigerator before reheating it.
