How to Make This Best Blueberry French Toast Casserole Recipe
- Prepare the bread: Cut the bread into 1-inch cubes and spread them in a single layer on a baking sheet. Bake at 300°F (150°C) for 10-15 minutes, or until lightly dried. Alternatively, allow the bread to sit out overnight to dry.
- Make the custard: In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt.
- Assemble the casserole: Grease a 9×13 inch baking dish. Place half of the dried bread cubes in the dish. Sprinkle 1 cup of blueberries over the bread. Top with the remaining bread cubes.
- Pour the custard: Slowly pour the custard mixture evenly over the bread. Gently press down on the bread to ensure it is soaked.
- Make the streusel: In a medium bowl, combine the flour, brown sugar, and cinnamon for the streusel. Cut in the cold butter using a pastry blender or your fingers, until the mixture resembles coarse crumbs.
- Add Streusel and Blueberries: Sprinkle the streusel topping evenly over the casserole. Distribute the remaining 1 cup of blueberries on top of the streusel.
- Chill if desired: For Best Blueberry French Toast Casserole, cover the dish with plastic wrap and refrigerate for at least 30 minutes, or up to overnight. This allows the bread to fully absorb the custard.
- Bake: Preheat oven to 375°F (190°C). Bake the casserole, uncovered, for 40-45 minutes, or until the top is golden brown and the custard is set. If the top begins to brown too quickly, cover loosely with foil.
- Cool and Serve: Let the casserole cool for 10 minutes before serving.
