Baked French Toast Casserole Ingredients
For the Casserole
- Crusty Sourdough or French Bread – A day-old loaf works best, offering the ideal texture to soak up the custard.
- Eggs – Large eggs enhance the richness and provide the necessary structure for the casserole.
- Whole Milk – Creamy and full-flavored, but feel free to use non-fat milk for a lighter dish.
- Heavy Cream – For that indulgent richness in the custard; half-and-half is a great alternative too.
- Granulated Sugar – Adds just the right amount of sweetness; you can reduce it if you prefer a less sweet casserole.
- Firmly Packed Brown Sugar – Deepens the flavors beautifully; coconut sugar works as a delightful substitute.
- Vanilla Extract – Pure vanilla extract infuses the dish with warmth and sweetness that elevates every bite.
- Butter – Use it to grease your pan and consider serving melted on top of warm slices for extra richness.
For the Streusel Topping
- Flour – Provides the necessary structure for a crunchy topping; gluten-free flour is a suitable alternative.
- Cinnamon – A warm spice that flavors both the streusel and custard; nutmeg can add a different aromatic touch if desired.
- Cold Butter – Ensure it’s chilled for creating that delightful crumbly texture in your streusel topping.
Optional Toppings
- Fresh Blueberries – These add a burst of freshness; you can swap for strawberries or blackberries to your liking.
- Warm Syrup – Maple syrup pairs beautifully with the casserole and elevates the overall flavor profile.

How to Make Baked French Toast Casserole
-
Prep Bread: Start by cubing the crusty sourdough or French bread and spreading it evenly into a greased 9×13 baking dish. This will form the cozy base of your casserole.
