Ingredients
Baked Brioche Casserole
- 1 loaf brioche bread diced (about 4-6 cups)
- 6 eggs
- 2 ½ cups whole milk
- ¼ cup maple syrup or agave syrup
- 2 teaspoons vanilla extract
- ⅛ teaspoon salt
- 1 teaspoon cinnamon
- ½ teaspoon nutmeg
Blueberry Sauce
- 3 cups fresh blueberries, divided
- 1 tablespoon agave
- 1 cup water
Toppings
- Powdered sugar (optional for serving)
Instructions
- Make Blueberry Sauce: Combine 2 cups of fresh blueberries, 1 teaspoon agave, and 1 cup water in a saucepan over medium-high heat. Cook for 5-6 minutes until bubbly, then gently break up the blueberries using the back of a wooden spoon. Reduce heat and continue cooking for another 5-7 minutes until the sauce thickens and reduces. Remove from heat and set aside.
- Prepare Custard Mixture: In a large mixing bowl, whisk together 6 eggs, 2 ½ cups whole milk, ¼ cup maple or agave syrup, 2 teaspoons vanilla extract, ⅛ teaspoon salt, 1 teaspoon cinnamon, and ½ teaspoon nutmeg until smooth and evenly combined.
- Assemble Casserole: Place the diced brioche bread evenly into a 9×13 casserole dish. Pour the prepared custard mixture over the bread, gently pressing the pieces down so they absorb the liquid thoroughly. Scatter the remaining 1 cup fresh blueberries evenly on top.
- Bake the Casserole: Preheat the oven to 350°F (175°C). Bake the casserole for 35-40 minutes or until the center is set and no longer jiggly, and the edges turn golden brown.
- Serve: When ready to serve, drizzle the warm blueberry sauce over the casserole and sprinkle with powdered sugar if desired. Enjoy your delicious blueberry brioche French toast casserole!
Notes
- Use slightly stale brioche bread for best texture, or dry fresh bread in the oven at 225°F (107°C) for 22-25 minutes to dry it out.
- Don’t skimp on the cinnamon and nutmeg; these spices give the dish its signature warm and comforting flavor.
- Get creative with toppings—try adding fresh fruits, nuts, or a drizzle of chocolate sauce for an indulgent twist.
