Ingredients
French Toast Casserole
- 1 pound sourdough or French bread cut into chunks
- 3 cups chopped apples about 2 large apples
- 8 large eggs
- 2 cups whole or 2% milk
- ½ cup heavy whipping cream
- ½ cup granulated sugar
- ¼ cup light brown sugar
- 2 teaspoons vanilla extract
- 1½ teaspoons ground cinnamon
Cinnamon Streusel Topping
- ¾ cup all-purpose flour
- ¾ cup packed brown sugar
- 1 teaspoon ground cinnamon
- 1½ teaspoons apple pie spice
- ½ cup cold salted butter cut into pieces
Instructions
- Grease a 9×13-inch baking dish. Layer the bread cubes and chopped apples evenly in the dish.
- Whisk together the eggs, milk, heavy cream, both sugars, vanilla, and cinnamon. Pour evenly over the bread and gently press down.
- Cover and refrigerate for at least 2 hours or overnight.
- Mix the flour, brown sugar, cinnamon, and apple pie spice. Cut in the cold butter until crumbly. Refrigerate separately.
- Preheat the oven to 350°F. Sprinkle the streusel over the casserole.
- Bake uncovered for 45–55 minutes until golden brown and the center is set. Tent with foil if the top browns too quickly.
- Cool for 5–10 minutes and serve warm with maple syrup or your favorite toppings.
Notes
For the best results, use day-old bread and keep the streusel refrigerated until baking. If baking directly from a very cold dish, allow extra time as needed and follow the baking dish manufacturer's temperature-change guidance.
