Overnight Crème Brûlée French Toast (Print version)

A make-ahead French toast bake with rich vanilla custard, thick bread, and a buttery caramel layer that bubbles up in the oven.

# Ingredients:

For the caramel layer

01 - 1/2 cup (113 g) unsalted butter
02 - 1 cup (200 g) packed light brown sugar
03 - 2 tablespoons light corn syrup or maple syrup

For the French toast

04 - 1 loaf (about 14 oz or 400 g) brioche, challah, or French bread, cut into 1-inch slices
05 - 5 large eggs
06 - 1 1/2 cups (360 ml) half-and-half
07 - 1/2 cup (120 ml) whole milk
08 - 2 teaspoons vanilla extract
09 - 1 teaspoon finely grated orange zest or 1 tablespoon orange liqueur, optional
10 - 1/4 teaspoon fine salt
11 - 2 tablespoons turbinado sugar

For serving

12 - Fresh berries, optional
13 - Lightly whipped cream, optional

# Instructions:

01 - Butter a 9 x 13-inch baking dish. Melt the butter, brown sugar, and corn syrup in a small saucepan over medium heat, stirring for 3-4 minutes until smooth and glossy. Pour into the dish and spread evenly.
02 - Arrange the bread slices over the caramel in a snug single layer. Trim pieces as needed to fill gaps without stacking too heavily.
03 - Whisk the eggs, half-and-half, milk, vanilla, orange zest or liqueur if using, and salt until fully combined with no visible egg streaks.
04 - Pour the custard evenly over the bread. Cover tightly and refrigerate for at least 8 hours or overnight.
05 - Remove the pan from the refrigerator while the oven heats to 350°F. Bake uncovered for 35-40 minutes, until puffed, golden, and set in the center.
06 - Sprinkle the top with turbinado sugar. Broil for 1-2 minutes or torch just until the sugar melts and darkens in spots. Rest for 5 minutes, then serve warm with berries or whipped cream.

# Good to know:

01 - Chill time is at least 8 hours and is not included in the prep or cook time.
02 - Serve warm for the best custardy texture and caramel sauce.
03 - No syrup is needed because the caramel layer is already sweet.
