Crème Brûlée French Toast Casserole is a dish that truly delivers indulgence for breakfast or brunch. You get the creamy richness of custard paired with the crispy caramel layer, all wrapped around buttery, custard-soaked bread. Prepped ahead and baked in the morning, it takes the stress out of hosting, and has routinely wowed my family on holidays and lazy weekends alike. If you are looking to impress with a make-ahead breakfast that tastes like dessert and feels like warm comfort, this casserole delivers every time.
The first time I served this for a brunch party it disappeared before I even sat down. Now it is my most requested recipe for holiday mornings.
Ingredients
- Unsalted butter: adds richness and helps create that signature caramel layer. Look for butter with a sweet cream base for best flavor
- Brown sugar: brings deep sweetness and a touch of molasses. Soft packed works best for melting
- Corn syrup: keeps the caramel smooth and stops it from crystallizing
- Large eggs: are essential for a creamy custard base. Use the freshest you can find
- Whole milk: delivers a luxuriously soft texture. Any higher-fat milk will also work
- Vanilla extract: provides warm flavor. Pure vanilla gives better aroma
- Salt: balances all the sweetness and enhances every bite
- Ground cinnamon: brings warmth and spice. Freshly ground cinnamon makes a big difference
- French bread: is sturdy and soaks up custard beautifully without falling apart. Choose a loaf with a crisp crust
Step-by-Step Instructions
- Make the Caramel Base:
- In a small saucepan over medium heat, melt the butter together with brown sugar and corn syrup. Stir occasionally as it cooks and thickens for about three to four minutes. You want the sugar fully dissolved and the sauce smooth so it will set into a glossy layer. Pour the hot caramel into the bottom of a nine by thirteen inch baking dish making sure to spread it all the way to the corners.
- Arrange the Bread:
- Cut your French bread into one inch slices and arrange tightly in a single layer over the caramel. Slight overlapping is fine. Each piece should be nestled in so it soaks up the custard later.
- Prepare the Custard:
- In a mixing bowl, whisk together the eggs, milk, vanilla, salt, and cinnamon until smooth and lightly frothy. Pour this mixture thoroughly over all of the bread. Press gently on the bread to help it absorb. Cover with plastic wrap and chill for at least four hours or overnight for best results.
- Bake:
- Let the casserole sit out for fifteen minutes to lose its chill while you preheat the oven to three hundred fifty degrees Fahrenheit. Bake uncovered on the middle rack for thirty five to forty minutes until the top is golden and caramelized. The edges should be crispy and the center just set but not dry.
- Serve:
- Allow to cool for a few minutes. When serving, flip each piece so the caramel side is facing up. Finish with fresh berries or a dusting of powdered sugar for an extra special touch. Enjoy the blend of crisp top and creamy inside.

The vanilla in this recipe always reminds me of my grandma’s holiday desserts. She loved the smell of baking custards and would hover by the oven hoping for a taste before anyone else. Now I always add a little extra vanilla just for her.
Storage Tips
Store any leftovers tightly covered in the fridge for up to three days. Warm slices in a low oven so the caramel loosens again and the bread stays fluffy and moist. If you want to freeze it, wrap pieces well and reheat straight from frozen though you might lose some crispiness on top.
Ingredient Substitutions
Try brioche or challah if you want an even richer result. Gluten-free bread can be swapped in for anyone with dietary needs. For a flavor twist, add a bit of nutmeg, cardamom, or a teaspoon of orange zest. You can even add a slosh of your favorite liqueur to the custard for an adult version.
Serving Suggestions
Top each slice with fresh raspberries or blueberries for a burst of tartness. Whipped cream or Greek yogurt balances the sweet caramel. For extra crunch, finish with toasted pecans or a sprinkle of coarse sugar during the last ten minutes of baking.

Cultural and Historical Context
French toast, also called pain perdu, has roots in ancient Rome and became popular in France for using up leftover bread. Crème brûlée’s custard and caramelized sugar element inspired this casserole and brings a dessert-like underline to a beloved breakfast. Merging these two traditions results in something both classic and inventive.
