Ingredients to Gather

• French bread – Thick slices of French bread soak up the rich custard overnight, creating a soft center with perfectly crisp edges once baked.
• Eggs – Eggs form the base of the custard, giving the French toast its structure and creamy, baked texture.
• Half and half – Half and half adds richness and body to the custard, making each bite extra indulgent.
• Milk – Milk lightens the custard slightly while keeping it smooth and pourable.
• Granulated sugar – Granulated sugar sweetens the custard without overpowering the warm spices.
• Vanilla – Vanilla brings a comforting, bakery-style aroma that enhances the overall flavor of the French toast.
• Cinnamon – Cinnamon adds cozy warmth and classic French toast flavor throughout the dish.
• Nutmeg – Nutmeg provides a gentle hint of spice that deepens the custard’s richness.
• Salt – A pinch of salt balances the sweetness and sharpens all the flavors.
• Maple syrup – Maple syrup infuses the custard with natural sweetness and a hint of caramel flavor.
• Butter – Butter creates a rich, glossy base for the praline topping and adds irresistible flavor.
• Light brown sugar – Light brown sugar melts into a soft, caramel-like topping with deep molasses notes.
• Pecans – Pecans add crunch and nutty sweetness to the praline topping.
• Light corn syrup – Light corn syrup helps the praline topping stay smooth and spoonable while baking, resulting in a sticky, golden finish.

Ingredients

French Toast Ingredients

1 loaf French bread (13 – 16 ounce)

8 large eggs

2 cups half and half

1 cup milk

2 tablespoons granulated sugar

1 teaspoon vanilla

1/4 teaspoon cinnamon

1/4 teaspoon nutmeg

dash salt

Praline Topping Ingredients

1/2 pound (2 sticks) butter

1 cup packed light brown sugar

1 cup chopped pecans

2 tablespoons light corn syrup

1/2 teaspoon cinnamon

1/2 teaspoon nutmeg

Maple syrup for serving

Directions

1. Slice French bread into 20 1-inch slices. Arrange slices in a generously buttered 9 x 13″ baking dish in two rows, overlapping the slices. In a large bowl, combine eggs, half-and-half, milk, sugar, vanilla, cinnamon, nutmeg, and salt, and beat with a rotary beater or whisk until blended, but not too bubbly. Pour the egg/milk mixture over the bread slices, making sure that each is evenly covered. Spoon some in between the slices. Cover with foil and refrigerate overnight.

2. The next day, preheat the oven to 350 degrees.

3. Combine the praline topping ingredients in a medium bowl and blend well.

4. Spread praline topping evenly over the bread and bake for 40 minutes, or until puffed and lightly golden. Serve Overnight French Toast Casserole with maple syrup.

Tips for Recipe

• Whisk the eggs, half-and-half, milk, and spices thoroughly to avoid eggy pockets.
• Let it rest overnight (8-12 hours) in the refrigerator so flavors fully develop, and the texture becomes custardy rather than dry.
• Cover tightly to prevent the French toast from drying out in the fridge.
• Add the praline topping just before baking, not the night before, so it stays crisp instead of melting into the custard.
• Spread topping evenly, but don’t pack it down; loose crumbles bake up crisp and golden.
• Pecans are classic, but walnuts or almonds work well, too, if that’s what you have.
• Let the casserole sit at room temperature for 20-30 minutes before baking to ensure even cooking.
• Bake uncovered until the praline topping caramelizes.
• If the top browns too quickly, loosely tent with foil near the end of baking.
• Serve with warm maple syrup, fresh berries, or a dusting of powdered sugar for a bakery-style finish.
