How to Make Baked French Toast Casserole
Here’s a simple overview of how to prepare this recipe. For the full ingredient list and measurements, check the recipe card at the bottom.
1. Prepare the Bread
Drying the bread is crucial for helping it soak up the custard perfectly. The drier the bread, the more flavorful your casserole will be.
- Overnight method: Cut the bread into cubes and leave them out overnight.
- Oven method: Spread the cubes on a baking sheet and bake at 250°F (120°C) for about 30 minutes, flipping halfway.
2. Combine the Wet Ingredients
In a large bowl, whisk together:
- Eggs
- Whole milk
- Vanilla extract
Make sure the mixture is smooth and well combined for the creamiest custard.
3. Add the Bread to the Egg Mixture
Toss the dried bread cubes in the custard until every piece is thoroughly coated. This ensures every bite is soft and flavorful.
4. Make the Streusel Topping
One of the highlights of this casserole is the crunchy topping. Traditionally, streusel uses flour, butter, and brown sugar. In this recipe, we switch out flour for quick-cooking oats for a heartier texture.
Tips for the perfect topping:
- Use cold butter to help it hold up during baking.
- Don’t have a pastry cutter? Two forks work just as well.
- Prefer flour? Replace 1/2 cup oats with 2/3 cup all-purpose flour.
- Only have rolled oats? Blend them briefly for a finer texture.
Baking and Serving
Pour the bread and custard mixture into a greased 9×13 inch baking dish. Sprinkle the streusel evenly over the top. Bake uncovered at 350°F (175°C) for 30-35 minutes or until the edges start to pull away from the dish. Serve warm with powdered sugar and maple syrup for the ultimate brunch experience.
Freezing Your French Toast Casserole
If you like prepping ahead, this casserole freezes beautifully. After mixing the bread and custard (before adding the streusel), wrap the dish securely with aluminum foil. It can be stored in the freezer for up to three months.
Tips for safe baking from frozen:
- Use an aluminum baking dish rather than glass or ceramic to prevent cracking.
- Bake frozen casserole at 350°F (175°C) for 20 minutes before adding the streusel.
- Continue baking for another 45 minutes until the topping is golden and crispy.
Freezing is perfect for holiday mornings or busy weekends—just pop it in the oven and enjoy a freshly baked breakfast without the morning prep.
Fun Variations
This French Toast Casserole is versatile, and you can tweak it to suit your tastes or the season:
- Berry French Toast Casserole: Add frozen strawberries, raspberries, or blueberries for a sweet, fruity twist.
- Apple French Toast Casserole: Stir in apple pie filling for a cozy fall flavor.
- Cranberry French Toast Casserole: Perfect for the holidays—use homemade cranberry sauce for a festive touch.
Each variation keeps the creamy custard base while adding exciting flavors and textures.
Substitutions for Dietary Restrictions
You don’t have to miss out if you have dietary needs:
- Gluten-free: Swap the bread for gluten-free bread. Double-check that the oats are gluten-free as well.
- Dairy-free: Use almond milk or coconut milk instead of whole milk, and swap butter in the streusel for a dairy-free alternative.
With these simple swaps, this casserole can be enjoyed by everyone at the table.
