This baked apple french toast casserole is a delightful twist on a classic breakfast dish. Combining the comforting flavors of cinnamon, vanilla extract, and apples, this recipe is perfect for a weekend brunch or a special holiday morning. The french bread soaks up the rich egg mixture, creating a custardy base that pairs beautifully with the sweet and tender apples on top.
Most of the ingredients for this recipe are common pantry staples, but you may need to pick up a few items at the supermarket. Make sure to get a fresh loaf of french bread for the best texture.

Ingredients For Baked Apple French Toast Casserole
French bread: The base of the casserole, providing a sturdy yet absorbent texture.
Eggs: These bind the ingredients together and create a custardy texture.
Milk: Adds moisture and richness to the egg mixture.
Vanilla extract: Enhances the flavor with a sweet, aromatic note.
Cinnamon: Adds warmth and spice to the dish.
Apples: Provide a sweet and slightly tart contrast to the rich custard.
Brown sugar: Adds sweetness and a hint of caramel flavor.
Butter: Adds richness and helps to create a golden, crispy top.
Technique Tip for This Recipe
When preparing the apples, consider using a mix of varieties such as Granny Smith and Honeycrisp for a balance of tartness and sweetness. To prevent the bread from becoming too soggy, allow the egg mixture to sit and absorb for at least 10 minutes before baking. This ensures that every piece is evenly soaked and results in a more uniform texture.
