This decadent crème brûlée French toast casserole has become my signature dish for holiday brunches and special family gatherings. The magical combination of custardy bread and caramelized sugar creates a dessert-like breakfast that feels luxuriously indulgent while being surprisingly simple to prepare.
I first created this for a Christmas morning breakfast when I needed something special that wouldn't keep me from opening presents with my children. Now it's requested for every birthday breakfast and holiday celebration in our home.
Ingredients
- Unsalted butter creates the rich caramel base that transforms into the signature crackly top
- Brown sugar provides deep molasses notes that plain sugar simply cannot match
- Corn syrup prevents crystallization in the caramel ensuring a smooth glossy finish
- Large eggs give structure and richness to the custard creating that crème brûlée texture
- Whole milk provides essential fat content for the silkiest custard avoid using reduced fat options
- French bread with its sturdy texture holds up perfectly to overnight soaking without becoming mushy
- Vanilla extract adds aromatic warmth use pure extract rather than imitation for best flavor
- Ground cinnamon optional but adds wonderful warmth that complements the caramel perfectly
Step-by-Step Instructions
- Make the Caramel Base
- Cook butter brown sugar and corn syrup in a saucepan over medium heat for 3-4 minutes stirring occasionally until completely smooth and slightly thickened. Watch carefully as it can burn quickly. Pour immediately into your baking dish tilting to coat the entire bottom surface evenly.
- Arrange the Bread
- Slice your French bread into thick 1-inch pieces and arrange them in a single layer over the caramel sauce. The thickness matters here too thin and they'll dissolve into the custard too thick and they won't absorb properly. Slight overlapping is fine just ensure complete coverage of the caramel base.
- Prepare the Custard
- Whisk eggs milk vanilla salt and cinnamon together until completely combined and slightly frothy. The whisking incorporates air which helps the custard bake evenly. Pour this mixture slowly over the bread making sure to coat every piece. Press down gently on the bread to encourage absorption then cover and refrigerate overnight allowing the flavors to meld and the bread to fully soak.
- Bake
- Preheat your oven to 350°F and let the casserole sit at room temperature for 15 minutes while the oven heats. This prevents thermal shock which can cause uneven baking. Bake uncovered for 35-40 minutes until the top is golden brown and the center is set but still slightly jiggly. The edges should pull slightly away from the dish when properly done.
- Serve
- After cooling for 5 minutes carefully invert slices onto plates so the caramelized side faces upward creating that beautiful crème brûlée effect. The contrast between the crispy caramel and custardy bread creates an irresistible texture experience that makes this dish so special.

My favorite part of this recipe is watching guests take their first bite when that caramelized sugar cracks and gives way to the creamy interior beneath. The look of surprise and delight never gets old even after years of serving this dish.
Make It Your Own
This casserole welcomes creative variations to match your taste preferences or the seasons. Try layering thinly sliced apples between the bread pieces in fall or adding orange zest to the custard for a citrusy brightness during winter months. For a truly decadent version add a layer of cream cheese chunks before pouring the custard which creates pockets of cheesecake-like richness throughout.
Perfect Pairings
While delicious on its own this casserole shines alongside contrasting flavors. Serve with crispy bacon or savory breakfast sausage to balance the sweetness. A fresh fruit salad with citrus elements cuts through the richness beautifully. For beverages a strong coffee with bitter notes or champagne mimosas provide the perfect counterpoint to the sweet casserole.
Troubleshooting Tips
If your casserole seems too wet in the center after the recommended baking time cover with foil and continue baking for 5-10 minutes longer. This protects the top from burning while allowing the center to set properly. Conversely if the top is browning too quickly before the center is done cover loosely with foil for the remainder of the baking time.

Common Questions
- → Can I prepare this casserole the same day I want to serve it?
While overnight soaking yields the best results, you can prepare it with a shorter soak time. Allow at least 4 hours of refrigeration to ensure the bread fully absorbs the custard mixture. If you're really pressed for time, let it soak for 2 hours, though the texture may be slightly less custardy.
- → What's the best bread to use for this dish?
French bread is specified in the original recipe, but brioche or challah make excellent substitutions for a richer, more decadent result. The key is using a sturdy bread that can absorb the custard without falling apart. Day-old bread works particularly well as it soaks up more custard.
- → How do I know when the casserole is properly baked?
The casserole is done when the top is golden brown and the custard has set. The edges should be slightly crispy while the center should be firm but still have a custardy texture. Insert a knife in the center - it should come out mostly clean with perhaps a few moist crumbs.
- → Can I make this dish dairy-free?
Yes, you can substitute unsalted butter with plant-based butter and whole milk with full-fat coconut milk or almond milk. The coconut milk will add a subtle coconut flavor that pairs nicely with the caramel, while almond milk will provide a lighter texture but less richness.
- → What are some good toppings to serve with this casserole?
Fresh berries provide a tart contrast to the sweetness, while a dusting of powdered sugar adds an elegant touch. Other excellent options include maple syrup, whipped cream, toasted nuts for crunch, or a dollop of vanilla yogurt. For special occasions, a scoop of vanilla ice cream transforms it into a dessert.
- → Can I freeze leftovers of this casserole?
Yes, leftovers can be frozen for up to 2 months. Cut into individual portions before freezing for easier reheating. Wrap tightly in plastic wrap and aluminum foil to prevent freezer burn. Thaw overnight in the refrigerator and reheat in a 350°F oven until warmed through, about 15-20 minutes.
