Overnight Crème Brûlée French Toast
Ingredients
| Ingredient | Quantity |
|---|---|
| Unsalted butter | 1/2 cup (1 stick) |
| Packed brown sugar | 1 cup |
| Light corn syrup | 2 tablespoons |
| Challah or brioche bread, sliced 1/2 inch thick | 1 loaf |
| Large eggs | 5 |
| Half-and-half cream | 1 1/2 cups |
| Vanilla extract | 1 teaspoon |
| Grand Marnier or orange liqueur (optional) | 1 teaspoon |
| Salt | 1/4 teaspoon |
| Granulated sugar (optional, for caramelizing) | 1/4 cup |
Instructions
Step 1: Make the Caramel Layer
In a saucepan over medium heat, melt the butter. Stir in the brown sugar and corn syrup, mixing until smooth and fully combined. Pour the caramel evenly into a 9×13-inch baking dish.
Step 2: Layer the Bread
Arrange the sliced bread in a single, even layer over the caramel mixture.
Step 3: Mix the Custard
In a bowl, whisk together the eggs, half-and-half, vanilla extract, Grand Marnier if using, and salt until smooth.
Step 4: Soak Overnight
Pour the custard evenly over the bread. Gently press the slices down so they absorb the liquid. Cover the dish and refrigerate for at least 8 hours or overnight.
Step 5: Bake
Preheat the oven to 350°F (175°C). Remove the casserole from the refrigerator while the oven heats. Bake for 35–40 minutes, until puffed, golden, and set through the center.
Step 6: Finish and Serve
Let the French toast rest briefly before serving. For an authentic crème brûlée finish, sprinkle the top with granulated sugar and caramelize using a kitchen torch until crisp and golden.
