3 large Granny Smith apples, peeled, cored, and sliced
for the french toast layer
6 large eggs
1½ cups milk
½ cup flour
2 teaspoons vanilla
2 Tablespoons sugar
½ teaspoon salt
1 teaspoon cinnamon
1 loaf french bread from the grocery store bakery department, cut into 1" cubes
whipped cream for serving (optional, but delicious!)
Instructions
Spray a 9x13" baking dish with nonstick spray. In a small saucepan, combine corn syrup, butter, and brown sugar over medium heat. Cook until butter is melted, then continue cooking for about 3 minutes, whisking often, until the mixture is smooth and slightly syrupy. Pour the mixture into the bottom of the prepared pan, then top with apple slices.
To make the french toast layer, whisk eggs, milk, flour, vanilla, sugar, salt, and cinnamon in a very large bowl until smooth. Add cubed bread to the bowl and fold gently with a rubber spatula until all of the bread is evenly coated. Pour the bread on top of the apples in the pan, cover with plastic wrap, and refrigerate overnight. Don't skip this step! The egg mixture needs time to soak into the bread or you'll end up with dry spots in your casserole.
In the morning, preheat the oven to 375°F. Remove the plastic from the pan, and place pan in the oven. Bake the french toast casserole for 35-40 minutes, until a knife inserted in the center comes out clean. Serve plain or topped with whipped cream.
