Best Bread To Use

The type of bread you use can make a big difference in the texture of your French toast casserole. Regular sandwich bread works just fine, but it’s a very moist bread.

So it’s best if it’s a bit dry or stale. This helps it absorb the egg mixture without becoming soggy.

If you want a slightly heartier texture, try using a loaf of French bread or another rustic-style bread. These sturdier breads hold their shape well during baking, giving the casserole a more classic French toast feel.

Ingredients

8 large eggs
2 1/2 cups milk
1/4 cup brown sugar
1 tablespoon white sugar
2 teaspoons ground cinnamon
2 teaspoons vanilla extract
4 large apples, peeled, cored, and diced
1 loaf of sandwich bread (about 16-18 cups cubed)

Topping

1/3 cup brown sugar
1/4 teaspoon ground cinnamon
2 tablespoons all-purpose flour
1 tablespoon butter, melted
