A cozy and delicious overnight French toast casserole featuring ripe peaches and a buttery streusel topping, perfect for stress-free brunches or weekend treats.

Ingredients

Scale
  • 8 cups cubed brioche or challah bread (about 10 ounces / 280 grams)
  • 3 ripe peaches, peeled and sliced
  • 6 large eggs, room temperature
  • 2 cups (480 ml) whole milk or half-and-half
  • 1/3 cup (65 grams) granulated sugar
  • 1 tablespoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 4 tablespoons (55 grams) cold cubed butter
  • 1/2 cup (60 grams) all-purpose flour
  • 1/3 cup (70 grams) packed brown sugar
  • Optional: a handful of chopped pecans or walnuts

Instructions

  1. Cube the brioche or challah into roughly 1-inch pieces. Peel peaches by scoring an X at the bottom and blanching in boiling water for 30 seconds, then plunge into ice water. Slice peaches thinly and set aside.
  2. In a large mixing bowl, whisk together eggs, milk, granulated sugar, vanilla extract, cinnamon, and salt until smooth and slightly frothy.
  3. Spread half of the cubed bread evenly in a 9×13-inch baking dish. Layer sliced peaches over the bread. Top with remaining bread cubes. Pour custard mixture evenly over the casserole, pressing down lightly to help soak.
  4. Cover the dish tightly with plastic wrap or foil and refrigerate overnight or at least 6 hours.
  5. In a medium bowl, combine flour, brown sugar, and optional nuts. Add cold cubed butter and work into the dry ingredients with a pastry cutter or fingers until mixture resembles coarse crumbs.
  6. Preheat oven to 350°F (175°C). Remove casserole from fridge, sprinkle streusel topping evenly over it, and bake uncovered for 45-50 minutes until custard is set and streusel is golden and crisp. A toothpick inserted in the center should come out clean.
  7. Let casserole rest for about 10 minutes before serving.

Notes

Use sturdy bread like brioche or challah to avoid mushy texture. Soaking overnight is key for best flavor and texture. Keep butter cold when making streusel for crumbly topping. Tent with foil if streusel browns too fast. For gluten-free, substitute bread and flour accordingly. Serve warm with maple syrup or powdered sugar. Reheat leftovers gently in oven to keep topping crisp.
