This overnight crème brûlée French toast transforms ordinary breakfast into a special occasion without morning stress. I discovered this recipe when hosting my first holiday brunch, and it quickly became my signature dish for every family gathering.
I originally created this recipe when trying to simplify Christmas morning breakfast prep. The delighted expressions on my family's faces when they first tasted the caramelized topping convinced me this would become our tradition.
Ingredients
- French bread: using day-old bread works best as it absorbs the custard without becoming soggy
- Large eggs: provide structure and richness to the custard base
- Heavy cream: creates luxurious texture – look for high quality cream without additives
- Whole milk: works with the cream for the perfect custard consistency
- Granulated sugar: sweetens the custard mixture without overpowering
- Vanilla extract: adds warmth and depth – use pure extract for best flavor
- Ground cinnamon: provides subtle spice that complements the caramel
- Salt: enhances all flavors and balances sweetness
- Unsalted butter: forms the base of the caramel sauce – use European style for extra richness
- Brown sugar: creates that signature crème brûlée flavor and texture
- Corn syrup: prevents crystallization in the caramel for a smooth finish
Step-by-Step Instructions
- Bread Arrangement:
- Slice your French bread into generous 1-inch pieces and arrange them snugly in a greased 9×13 baking dish. For best results, use bread that's slightly stale as it will better absorb the custard mixture without falling apart.
- Custard Creation:
- In a large bowl, thoroughly whisk together the eggs, heavy cream, milk, granulated sugar, vanilla extract, cinnamon, and salt until completely combined. The mixture should be smooth with no visible egg strands. Pour this custard evenly over your arranged bread slices, taking care to coat each piece. Press down gently on the bread to encourage absorption.
- Overnight Rest:
- Cover the dish tightly with plastic wrap and refrigerate for at least 8 hours or overnight. This resting period is crucial as it allows the bread to fully absorb the custard, resulting in a pudding-like interior once baked. The longer it rests, the more developed the flavor becomes.
- Caramel Preparation:
- The next morning, preheat your oven to 350°F and prepare the caramel sauce. In a saucepan over medium heat, combine the butter, brown sugar, and corn syrup. Stir constantly until the butter melts completely and the mixture becomes smooth and slightly thickened, about 3 to 4 minutes. Do not allow it to boil or it may crystallize.
- Baking Process:
- Remove your soaked bread from the refrigerator and uncover. Pour the warm caramel sauce evenly over the top, ensuring each piece gets coated. Place in the preheated oven and bake for 35 to 40 minutes. The French toast is done when the top is gloriously golden brown, the caramel is bubbling around the edges, and the center has puffed up significantly.
- Final Touch:
- Allow the French toast to cool for 5 to 10 minutes before serving. This cooling period lets the caramel set slightly so it doesn't immediately run off the bread when served. The top will have a crackly caramelized crust reminiscent of crème brûlée, while the interior remains custardy and tender.

The corn syrup in this recipe is my secret weapon. While many home cooks try to avoid it, just two tablespoons prevents the caramel from crystallizing and creates that perfect crackly top. My grandmother taught me this trick, and I've never had a failed batch since implementing it.
Serving Suggestions
This crème brûlée French toast truly shines when served warm from the oven with a dusting of powdered sugar. For an extra special presentation, add fresh berries which provide a tart contrast to the sweet caramel. Maple syrup is entirely optional, as the caramelized sugar creates its own delicious sauce, but a small pitcher on the side allows guests to adjust to their preference. I like to complete the breakfast spread with a side of crispy bacon or breakfast sausage to balance the sweetness.
Storage and Reheating
Leftover French toast will keep in the refrigerator for up to 3 days when stored in an airtight container. To reheat, cover with foil and warm in a 325°F oven for about 15 minutes until heated through. The microwave works in a pinch but will soften the caramelized top. For best results, avoid freezing this dish as the custard texture can become grainy when thawed.
Ingredient Substitutions
While the original recipe creates the authentic crème brûlée experience, several adaptations work beautifully. Challah or brioche can replace French bread for an even richer result. For a dairy-sensitive version, substitute coconut cream for heavy cream and almond milk for whole milk. The granulated sugar can be swapped for coconut sugar, though it will darken the custard slightly. Maple syrup can replace corn syrup in the caramel, though watch carefully as it may caramelize more quickly.

Seasonal Variations
Transform this classic recipe throughout the year by incorporating seasonal elements. For fall, add 1/4 teaspoon of pumpkin pie spice to the custard and top with toasted pecans before serving. During summer, layer fresh peach slices between the bread pieces before pouring the custard. Winter holidays call for a teaspoon of orange zest in the custard and a garnish of sugared cranberries. Spring brunches benefit from a light lemon zest addition and a topping of fresh strawberries.
