Description
This Overnight French Toast Casserole is your new go-to for an easy and indulgent breakfast. Made with buttery brioche and a rich vanilla custard, it’s the perfect make-ahead dish for brunches, holidays, or cozy weekends.
Ingredients
8 slices brioche bread
6 large eggs
1 cup heavy cream
1 cup whole milk
1/2 cup granulated sugar
2 teaspoons vanilla extract
1 teaspoon ground cinnamon
2 tablespoons melted butter
Powdered sugar (for garnish, optional)
Instructions
1. Slice brioche into thick 1 to 1.5-inch slices and arrange in a greased 9×13-inch baking dish.
2. In a large bowl, whisk eggs, heavy cream, milk, sugar, vanilla, cinnamon, and melted butter.
3. Pour the custard mixture evenly over the brioche slices. Gently press to soak.
4. Cover tightly and refrigerate overnight.
5. Preheat oven to 350°F (175°C). Let casserole rest at room temp for 20 minutes.
6. Bake uncovered for 40–45 minutes until golden and set.
7. Rest for 10 minutes before serving. Top with powdered sugar or syrup if desired.
Notes
Use day-old brioche for best custard absorption.
Don’t skip the overnight soak—it ensures the custard sets perfectly.
Reheat leftovers in the oven or air fryer to keep edges crispy.
