Classic Cinnamon Streusel Overnight Casserole Ingredients
- 1 (16-ounce) loaf of French bread, cut into 1-inch cubes (about 10 cups)
- 8 large eggs
- 2 ¼ cups whole milk
- ½ cup heavy cream
- ¾ cup granulated sugar
- 1 tablespoon pure vanilla extract
- 1 ½ teaspoons ground cinnamon
- ¼ teaspoon salt
- For the Cinnamon Streusel Topping:
- ¾ cup all-purpose flour
- ½ cup packed light brown sugar
- 1 teaspoon ground cinnamon
- ¼ teaspoon salt
- 6 tablespoons unsalted butter, cold & cubed
How to Make Classic Cinnamon Streusel Overnight Casserole
Step 1: Prep the Bread Base
Grease a 9x13-inch baking dish. Arrange the bread cubes evenly inside. In a large mixing bowl, whisk together eggs, milk, heavy cream, granulated sugar, vanilla, cinnamon, and salt. Pour this luscious custard all over the bread, pressing lightly to submerge. Cover tightly with foil and store in the refrigerator overnight (at least 8 hours).
Step 2: Mix the Streusel Topping
In a medium bowl, stir together flour, brown sugar, cinnamon, and salt. Add the cold cubed butter and use a pastry cutter (or your fingers) to work it into coarse crumbs. Cover and refrigerate.
Step 3: Bake the Casserole
In the morning, preheat oven to 350°F (175°C). Take the casserole and streusel out of the refrigerator while the oven heats. Sprinkle streusel evenly across the casserole. Bake uncovered for 45-55 minutes, until golden brown and set. If you prefer a softer center, bake for 45 minutes; for a firmer texture, go up to 55 minutes.
Step 4: Serve & Enjoy!
Let your Classic Cinnamon Streusel Overnight Casserole cool for 10 minutes before slicing. Serve warm and enjoy the cozy, cinnamon-filled aroma!
Notes for the Best Classic Cinnamon Streusel Overnight Casserole
- Day-old or slightly stale bread works best for soaking up the custard without becoming mushy.
- If you notice the top browning too quickly, loosely cover the dish with foil during the last 15 minutes of baking.
Classic Cinnamon Streusel Casserole Variations
- Apple Cinnamon: Add 1 ½ cups chopped apples between the bread layers for fruity bursts.

- Can I assemble and bake the same day? For best results, let the casserole soak at least 4 hours, but overnight is ideal for maximum flavor and texture.
- How do I prevent the streusel from burning? If you notice over-browning, loosely tent the casserole with foil toward the end of baking.
