Simple Ingredients
Bread: I think French bread is the best bread for this casserole, but you can use other bread varieties like sourdough bread, brioche, challah, and croissants. Any of these options would work nicely.
Blueberries: You can use fresh blueberries or thawed frozen blueberries.
Eggs: Use large, if your eggs are medium or small you may want to add a couple more.
Milk: Whole milk for the full richness in the flavor profile
Spices: Cinnamon and ground nutmeg
Vanilla extract
Brown Sugar: Either light or dark will work. I also top it with optional powdered sugar
Flour: all-purpose flour for topping
Butter: keep it cold and cut into small pieces
Pecans: or other chopped nuts for topping. You can omit the nuts if desired.
How to Make This Blueberry French Toast Casserole
Step 1: In a large bowl, whisk the eggs, milk, spices, brown sugar, and vanilla extract together.
Step 2: Cut crusty French bread into 1-inch cubes and place in a large bowl. Pour egg mixture over the cubed bread toss to coat and let soak.
Step 3: In a small bowl, add the topping ingredients. Use a pastry cutter or fork to blend together until crumbly.
Step 4: Transfer soaked crusty bread to a prepared baking dish. Add blueberries with the topping on top of the French Toast Casserole. Sprinkle with crunchy topping on top and bake!
Recipe Tips
This can be served as is, with powdered sugar sprinkled on top, or drizzled with real maple syrup.
Super soft, fresh bread actually isn’t ideal. If your bread slices are a few days old, or even a little stale, they’ll soak up the egg custard mixture even better.
Blueberries aren’t the only great option here. You can make this with any fresh berries. Strawberries and raspberries with the blueberries would really make this the best French toast casserole.
Leftover casserole should be stored in an airtight container for up to 3-4 days in the refrigerator. Or freeze for up to 3 months, thaw before reheating in the oven.
