French Toast Casserole – The Easiest Way to Make It

Step 1: Prepare Bread Cubes

Cut bread into bite-sized cubes and spread them evenly in a generously buttered 9×13-inch baking dish.

Choose a sturdy bread like brioche or challah for the best texture and flavor.

Step 2: Create Creamy Custard Base

• Eggs
• Whole milk
• Heavy cream
• White sugar
• Brown sugar
• Vanilla extract
• Ground cinnamon
• Ground nutmeg
• Pinch of salt

Blend until all ingredients are completely smooth and well combined.

Step 3: Soak Bread Overnight

Pour the custard mixture over the bread cubes, gently pressing down to ensure every piece gets thoroughly coated.

Cover the baking dish with plastic wrap and refrigerate for at least 8 hours or overnight to allow bread to absorb all the delicious flavors.

Step 4: Craft Crumbly Topping

• Brown sugar
• All-purpose flour
• Softened butter
• Ground cinnamon

Use your fingers to create a crumbly, streusel-like texture.

Step 5: Bake to Golden Perfection

Preheat the oven to 350°F.

Sprinkle the prepared crumbly topping evenly across the soaked bread casserole.

Bake for 40-45 minutes until the top turns a beautiful golden brown and the center is set but slightly jiggly.

Step 6: Serve and Enjoy

Remove from the oven and let cool for 10 minutes.

Serve warm with maple syrup, a dusting of powdered sugar, fresh berries, or a dollop of whipped cream.

French Toast Casserole Made Perfect With Step-by-Step Tricks

• Soak bread overnight to allow ingredients to fully absorb and develop deeper, richer taste profiles.

Reheat French Toast Casserole Sweet And Soft
