A cozy and effortless overnight baked French toast casserole topped with a crunchy cinnamon streusel, perfect for a comforting breakfast or brunch.

Ingredients

Scale
  • 1 loaf brioche or challah bread, cut into 1-inch cubes (day-old bread works best)
  • 6 large eggs, room temperature
  • 2 cups whole milk (can substitute almond or oat milk for dairy-free)
  • 1/2 cup heavy cream (optional for extra richness; use more milk if skipping cream)
  • 3/4 cup granulated sugar
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg (optional)
  • Pinch of salt
  • For the cinnamon streusel topping:
  • 1/2 cup all-purpose flour
  • 1/2 cup packed light brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/4 cup unsalted butter, cold and cubed (can use vegan butter if needed)
  • Optional toppings:
  • Maple syrup or powdered sugar for serving
  • Fresh berries or sliced bananas for garnish

Instructions

  1. Cut the brioche or challah into 1-inch cubes and spread on a baking sheet to dry out slightly for about 10 minutes.
  2. In a large bowl, whisk together eggs, whole milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt until smooth.
  3. Place the cubed bread in a 9×13-inch baking dish and pour the custard mixture evenly over the bread, pressing gently to soak all pieces.
  4. Cover the dish tightly with plastic wrap or foil and refrigerate for at least 6 hours or overnight.
  5. In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Add cold cubed butter and use a pastry cutter or forks to blend until coarse crumbs form.
  6. Preheat oven to 350°F (175°C). Remove casserole from fridge and sprinkle the cinnamon streusel evenly over the soaked bread.
  7. Bake uncovered for 45-50 minutes until the top is golden brown and custard is set (a knife inserted should come out clean).
  8. Let the casserole rest for 10 minutes before serving to allow the streusel to crisp up.
  9. Serve warm with maple syrup, powdered sugar, or fresh fruit as desired.

Notes

Soaking the bread overnight is essential for the perfect custardy texture. Use day-old brioche or challah for best results. Keep butter cold when making streusel to ensure a crunchy topping. If casserole seems too wet, bake longer and cover topping loosely with foil if browning too fast. Reheat leftovers in oven to preserve streusel crispness; avoid microwaving.
