Easy Make Ahead French Toast Casserole - featured image

A simple and delicious make-ahead French toast casserole with cinnamon that soaks overnight for a custardy, soft center and crispy golden edges. Perfect for busy mornings and customizable with nuts, fruits, or dairy-free options.

Ingredients

Scale
  • 6 cups (about 180g) day-old bread (brioche, challah, or sturdy white bread), cut into 1-inch cubes
  • 6 large eggs (room temperature)
  • 2 cups (480 ml) whole milk or half-and-half (can substitute almond milk for dairy-free)
  • 1/4 cup (50g) granulated sugar
  • 1 tablespoon ground cinnamon
  • 1 teaspoon pure vanilla extract
  • Pinch of salt
  • 2 tablespoons unsalted butter, diced (for dotting on top before baking)
  • Optional: 1/4 cup chopped pecans or walnuts

Instructions

  1. Cut about 6 cups (180g) of day-old bread into 1-inch cubes and spread evenly in a greased 9×13 inch baking dish.
  2. In a large bowl, whisk together 6 large eggs, 2 cups (480 ml) whole milk or half-and-half, 1/4 cup (50g) granulated sugar, 1 tablespoon ground cinnamon, 1 teaspoon vanilla extract, and a pinch of salt until fully combined and slightly frothy.
  3. Slowly pour the custard evenly over the bread cubes in the baking dish. Press the bread gently down with a spatula to help it absorb the liquid.
  4. Cover tightly with plastic wrap or aluminum foil and refrigerate for at least 4 hours, ideally overnight.
  5. Preheat oven to 350°F (175°C). Remove casserole from fridge about 15 minutes before baking to take the chill off.
  6. Dot the top with 2 tablespoons diced unsalted butter and sprinkle chopped nuts or a little brown sugar if desired.
  7. Bake uncovered for 45-55 minutes until edges are golden brown and crispy and the center is just set (a knife inserted should come out clean but moist). Tent with foil if top browns too quickly.
  8. Let cool for 10-15 minutes before serving. Serve warm with maple syrup, fresh fruit, or powdered sugar.

Notes

Use day-old or slightly stale bread for best texture. Let the casserole soak overnight for full custard absorption. Dotting butter on top before baking creates golden, crispy pockets. Tent with foil if top browns too fast. Adjust milk or baking time if texture is too soft or dry. Can substitute gluten-free bread and plant-based milk for dietary needs.
