Ingredients
- Brioche or other bakery-style bread: 1 loaf, cut into 1½” cubes. Day-old or slightly stale bread is best so it soaks up the custard without turning mushy. If the loaf is very fresh, spread the cubes on a sheet and dry at 275°F for 5–15 minutes.
- Blueberries or other fruit: 2 cups total (or use strawberries, raspberries, chopped apples, or chocolate chips).
- Eggs: 6 large eggs.
- Half-and-half: 3 cups. (Substitute with 1½ cups whole milk + 1½ cups heavy cream if needed.)
- Packed brown sugar: ½ cup.
- Lemon juice: 1 tablespoon.
- Vanilla extract: 1½ teaspoons.
- Ground cinnamon: 1½ teaspoons; nutmeg: ½ teaspoon.
For serving (optional)
- Powdered sugar
- Maple syrup
- Whipped cream

How to Make French Toast Casserole
This make-ahead baked French toast is ideal for busy mornings or holiday breakfasts. The family-friendly flavors and simple prep make it a repeat favorite.
Step one: In a large bowl whisk together eggs, half-and-half, lemon juice, vanilla, cinnamon, nutmeg, and brown sugar until well combined.
Adding the Bread Cubes
Step two: Grease a 9×13″ baking dish. Layer half of the bread cubes evenly in the dish, sprinkle 1 cup of blueberries (or your chosen mix-in) over the bread, then add the remaining bread cubes and the rest of the blueberries.
Soaking and Baking
Step three: Pour the custard evenly over the bread and berries. Press the top pieces gently with a spoon or spatula to ensure the cubes are submerged and absorb the liquid.
Step four: Cover and refrigerate for at least 1 hour; overnight yields the best texture and flavor as the bread fully soaks up the custard.
Overnight method
Assemble the casserole, cover tightly, and chill overnight. In the morning place the cold dish into a cold oven, then set the oven to 350°F (177°C) so the dish warms gradually and avoids thermal shock. Alternatively, let the dish come to room temperature before baking.
Step five: Bake uncovered at 350°F (177°C) for 45–55 minutes, or until the custard is set and the top is golden. If the surface browns too quickly, tent lightly with foil and finish baking.
Step six: Remove from oven, dust with powdered sugar if desired, slice, and serve with maple syrup, whipped cream, or extra berries.
What to Serve with Baked French Toast
This casserole is hearty enough to stand alone, but it also pairs beautifully with a brunch spread. Consider serving with:
- Sausage or bacon
- Scrambled eggs or an egg frittata
- Fresh fruit salad or sliced berries
- Hashbrown casserole or roasted potatoes
- Smoothies, orange juice, or mimosas
Storing and Reheating
Storing: Refrigerate leftovers in an airtight container for up to 3 days.
Reheating: Warm individual portions in the microwave in 30-second intervals until heated through, or reheat in a 350°F oven until warm and crisp on top.
Freezing: Freeze the casserole either before baking or after baking and cooling. Thaw in the refrigerator overnight before baking or reheating as needed.
Choosing Bread
- Brioche is ideal for its rich, tender crumb, but French bread, sourdough, or challah work well too.
- Use slightly stale or dried bread so it soaks up the custard without collapsing. To dry fresh bread, cube it and bake at 275°F for 5–15 minutes, checking and flipping occasionally.
Substitutions and Variations
- Half-and-half substitute: Use 1½ cups whole milk + 1½ cups heavy cream to replace 3 cups half-and-half.
- Frozen fruit: Frozen berries are fine, but they may tint the casserole as they release juice.
- Variations: Try raspberries, strawberries, chopped apples, bananas and walnuts, chocolate chips, or a brown sugar and nut topping for extra sweetness and texture.
Recipe Summary
Brioche French Toast Casserole — Serves: 8. Prep time: about 25 minutes plus soaking (1 hour to overnight). Bake: 45–55 minutes at 350°F (177°C). Calories (approx.): 432 per serving. This comforting, crowd-friendly casserole is perfect for holidays and special mornings.
Notes
- Stale bread gives the best texture—if fresh, dry the cubes in a low oven before assembling.
- If baking straight from the fridge, put the cold dish into a cold oven and then preheat to prevent temperature shock and reduce the risk of the dish cracking.
