French Toast Casserole

Jump to Recipe

French Toast Casserole is a cozy, make-ahead breakfast bake that turns classic French toast into an easy, crowd-friendly dish. Instead of dipping and frying individual slices of bread, cubed bread is soaked in a sweet cinnamon-vanilla custard, then baked until golden on top and soft in the center. It’s especially popular for holidays, brunch gatherings, and slow weekend mornings because most of the prep can be done ahead of time.

Why You’ll Love French Toast Casserole

You’ll love French Toast Casserole because it has all the warm, nostalgic flavor of traditional French toast with far less hands-on work. The inside bakes up soft, rich, and custardy, while the top becomes lightly crisp and golden. It’s perfect for feeding a group, easy to customize with fruit or nuts, and can be assembled the night before so breakfast feels effortless in the morning.

Expert Tips and Tricks

  • Use sturdy bread like brioche, challah, French bread, or sourdough so the casserole does not turn mushy.
  • Slightly stale or dried-out bread absorbs the custard better than fresh bread.
  • Cut the bread into evenly sized cubes so it soaks and bakes evenly.
  • Let the casserole rest before baking, ideally overnight, for the best flavor and texture.
  • Press the bread gently into the custard so every piece gets coated.
  • Cover with foil for the first part of baking if you prefer a softer top.
  • Let the casserole rest for 10 minutes after baking so it slices more neatly.
  • Add the maple syrup after baking rather than before to keep the top from becoming too wet.

Recipe Variations and Possible Substitutions

  • Use brioche for a rich, buttery casserole or French bread for a slightly firmer texture.
  • Add fresh blueberries, sliced strawberries, diced apples, peaches, or bananas before baking.
  • Stir chopped pecans, walnuts, or almonds into the topping for crunch.
  • Add orange zest, almond extract, pumpkin pie spice, or nutmeg for extra flavor.
  • Swap the brown sugar topping for a cinnamon streusel topping.
  • Gluten-Free: Use a sturdy gluten-free bread and make sure all ingredients are certified gluten-free.
  • Dairy-Free: Use almond milk, oat milk, coconut milk, or another dairy-free milk, and replace butter with vegan butter.
  • Nut-Free: Skip nut add-ins and use nut-free milk if making it dairy-free.
  • Lower Sugar: Reduce the brown sugar in the custard and topping, then serve with fresh fruit.

Serving and Pairing Suggestions

Serve French Toast Casserole warm with maple syrup, powdered sugar, fresh berries, whipped cream, or a spoonful of yogurt. It pairs beautifully with crispy bacon, breakfast sausage, scrambled eggs, fresh fruit salad, or roasted potatoes for a complete brunch spread. For drinks, serve it with hot coffee, iced coffee, orange juice, chai tea, or a cinnamon latte.

Storage and Reheating Tips

  • Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • Cover the baking dish tightly with foil or plastic wrap if storing the casserole in the same pan.
  • Reheat individual portions in the microwave for 30–60 seconds, until warmed through.
  • Reheat larger portions in a 325°F oven, covered with foil, for 15–20 minutes.
  • Use a toaster oven at 325°F for 8–10 minutes to bring back a lightly crisp top.
  • Air fry individual pieces at 320°F for 3–5 minutes for crispier edges.
  • Freeze baked portions for up to 2 months in freezer-safe containers.
  • Thaw frozen portions overnight in the refrigerator before reheating.

Recipe FAQs

  • Can I make French Toast Casserole the night before? Yes, this recipe is perfect for overnight prep. Assemble it, cover it, refrigerate it, and bake it the next morning.
  • What bread is best for French Toast Casserole? Brioche, challah, French bread, and sourdough work best because they are sturdy and absorb custard well.
  • Can I use fresh bread? Yes, but it is best to dry it out first by leaving it uncovered for a few hours or baking the cubes briefly at a low temperature.
  • Why is my casserole soggy? It may have too much custard, the bread may be too soft, or it may need more baking time. Use sturdy bread and bake until the center is set.
  • How do I know when it is done? The top should be golden, the edges should be set, and the center should no longer look wet or liquidy.
  • Can I add fruit? Yes, berries, apples, peaches, and bananas are all delicious additions.
  • Do I serve it with syrup? Yes, maple syrup is classic, but powdered sugar, fruit sauce, caramel, or whipped cream also work well.

French Toast Casserole is an easy make-ahead breakfast bake with cinnamon custard, golden bread, and a sweet crumb topping. Perfect for brunch.

Ingredients

  • 1 large loaf brioche, challah, or French bread, about 14–16 ounces, cut into 1-inch cubes
  • 8 large eggs
  • 2 1/2 cups whole milk
  • 1/2 cup heavy cream
  • 1/2 cup packed light brown sugar
  • 1/4 cup granulated sugar
  • 2 teaspoons vanilla extract
  • 2 teaspoons ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1/4 teaspoon salt
  • 2 tablespoons unsalted butter, softened, for greasing the pan

For the Brown Sugar Topping

  • 1/2 cup packed light brown sugar
  • 1/2 cup all-purpose flour
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup cold unsalted butter, cut into small cubes

For Serving

  • Maple syrup
  • Powdered sugar
  • Fresh berries
  • Whipped cream, optional

Instructions

  1. Prepare the baking dish: Grease a 9×13-inch baking dish with the softened butter. Make sure to coat the bottom and sides well so the casserole does not stick.
  2. Cut the bread: Cut the bread into 1-inch cubes. If the bread is very fresh and soft, spread the cubes on a baking sheet and let them sit uncovered for a few hours. For a quicker method, bake the bread cubes at 300°F for 10–15 minutes, just until slightly dried but not browned.
  3. Add bread to the dish: Place the bread cubes evenly into the prepared baking dish. Spread them out so the casserole has an even layer from corner to corner.
  4. Make the custard: In a large mixing bowl, crack the eggs and whisk until the yolks and whites are fully combined. Add the milk, heavy cream, brown sugar, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt. Whisk well until the mixture looks smooth and the spices are evenly distributed.
  5. Pour custard over the bread: Slowly pour the custard mixture over the bread cubes. Try to pour evenly across the whole pan so every section gets coated.
  6. Press the bread down gently: Use clean hands or the back of a spoon to gently press the bread into the custard. Do not smash it; just press enough so the top pieces absorb some liquid.
  7. Cover and chill: Cover the baking dish tightly with foil. Refrigerate for 15-30 minutes. This gives the bread time to soak up the custard.
  8. Make the topping: In a medium bowl, combine the brown sugar, flour, cinnamon, and salt. Add the cold butter cubes. Use a pastry cutter, fork, or your fingertips to work the butter into the dry ingredients until the mixture forms crumbly pieces about the size of peas.
  9. Preheat the oven: When ready to bake, preheat your oven to 350°F. Remove the casserole from the refrigerator while the oven heats so the dish can drop temperature for at least 10 minutes. This helps it bake more evenly.
  10. Add the topping: Sprinkle the brown sugar topping evenly over the soaked bread. Try to cover the whole surface so every serving gets a sweet, crumbly top.
  11. Bake the casserole: Bake loosely covered with foil for 30 minutes, and then remove the foil cover for the remaining time. For a softer casserole, bake closer to 45 minutes. For a firmer, more golden casserole, bake closer to 55 minutes. If the top browns too quickly, loosely cover it with foil again during the last 10–15 minutes.
  12. Check for doneness: The casserole is ready when the top is golden brown, the edges look set, and the center no longer looks wet. A knife inserted near the center should come out mostly clean, though it may be slightly moist from the custard.
  13. Rest before serving: Remove the casserole from the oven and let it rest for 10 minutes. This helps the custard finish setting and makes it easier to slice.
  14. Serve: Cut into squares and serve warm with maple syrup, powdered sugar, fresh berries, or whipped cream.

Notes

  • For the best texture, use bread that is at least a day old.
  • Add the topping right before baking so it stays crumbly and does not dissolve into the custard.
  • For extra richness, replace 1/2 cup of milk with more heavy cream.
  • For a holiday flavor, add a pinch of cloves and allspice.
  • To prevent a cold glass baking dish from cracking, let it sit at room temperature before placing it in the hot oven.
