Notes & Substitutions

• Butter: For a dairy-free option, substitute with vegan butter sticks or coconut oil.
• Sweetener: You can adjust the amount of brown sugar in the caramel layer or custard. A drizzle of maple syrup can also sweeten the egg mixture.

Equipment

You won’t need many special tools for this easy breakfast casserole:

• 9×13 inch baking dish
• Small saucepan
• Large mixing bowl
• Whisk
• Measuring cups and spoons
• Optional: large baking sheet (for catching any potential overflow)

Instructions

Creating this delightful French toast casserole is straightforward. Just follow these steps for a perfect breakfast or brunch dish.

1. Prep Oven and Pan: Preheat your oven to 425 degrees F (220 C). Generously butter a 9×13 inch baking pan and set it aside. This step helps prevent sticking and adds flavor.
2. Make Caramel Layer: In a small saucepan, melt the ½ cup of butter over medium heat. Once the butter has completely melted, stir in the 1 cup of packed brown sugar until it dissolves and the mixture becomes smooth and bubbly. Carefully pour this warm caramel mixture into the bottom of your prepared 9×13 pan and spread it evenly across the base. This forms the delicious, sticky bottom of your French toast bake.
3. Arrange Bread: Take your cubed French bread and evenly spread it over the top of the brown sugar and butter mixture in the baking pan. Try to distribute the bread cubes so they form a single layer, ensuring even baking.
4. Whisk Custard: In a medium-sized mixing bowl, whisk together the 6 large eggs until they are well beaten. Add the 2 cups of milk, 2 teaspoons of vanilla extract, and 1 teaspoon of the ground cinnamon to the bowl. Whisk everything together thoroughly until the custard mixture is smooth and all ingredients are fully combined. This is the heart of your French toast casserole recipe.
5. Pour & Top: Carefully pour the prepared egg custard mixture over the bread cubes in the baking pan. Make sure that all pieces of bread are well-saturated with the liquid; gently press down on any floating pieces to help them soak up the custard. This ensures a moist and flavorful interior. Sprinkle the remaining 1 teaspoon of cinnamon and 1 tablespoon of brown sugar evenly over the top of the casserole.
6. Bake: Place the baking pan into the preheated 425-degree F oven. Bake for 25-30 minutes, or until the top is beautifully golden brown and the custard is set in the center. A knife inserted into the center should come out clean.
7. Serve: Remove the baked French toast casserole from the oven. If desired, sprinkle with powdered sugar immediately for a festive finish. Let it cool for a few minutes before slicing and serving warm.

Pro Tips & Troubleshooting

Ensure your French toast casserole turns out perfect every time with these helpful hints.

• Prevent Soggy Casserole: Always use stale or dried bread. Fresh bread absorbs too much liquid and can become mushy. Let bread sit out overnight or lightly toast cubes for 10 minutes. According to Allrecipes, using toasted or stale bread for French toast is a simple trick to ensure better absorption and a perfect texture.
• Avoid Over-Eggy Taste: Ensure your bread cubes are completely saturated with the custard. This balances the egg-to-bread ratio, preventing a strong eggy flavor in your French toast bake.
• Prevent Bubbling Over: Place a large baking sheet underneath your casserole dish while baking. This catches any potential spills from the caramel or custard, saving you from oven cleanup.
• Achieve Golden-Brown Top: If your casserole isn’t as golden as you’d like after baking, broil it for 1-2 minutes. Watch it very closely to prevent burning.
• Adjust Sweetness: For a less sweet dish, you can reduce the brown sugar in the caramel layer and the topping. You can always add more syrup at the table.

Variations

• Fruity: Fold in a cup of fresh or frozen berries, sliced bananas, or diced apples with the bread cubes.
