Equipment

Ingredients

¾ cup Butter unsalted
1 ¼ cup Brown Sugar
3 Tablespoons Maple Syrup
1 loaf French Bread
6 Eggs
2 cups Half and Half
1 ½ teaspoons Vanilla Extract
3 Tablespoons Grand Marnier
¼ teaspoon salt

Instructions

In a small saucepan, melt the butter over medium-low heat, stirring occasionally until it is fully melted and smooth.
Add the brown sugar and maple syrup to the melted butter. Stir continuously until the brown sugar is completely dissolved and the mixture is smooth.
Remove the saucepan from the heat and carefully pour the warm caramel mixture into the bottom of a 9x13-inch baking dish.
Tilt the dish gently or use a spatula to spread the mixture evenly across the entire bottom, creating a smooth layer.
In a medium mixing bowl, crack the eggs and whisk them vigorously until they are well beaten and slightly frothy, about 30–45 seconds.
Pour in the half and half and vanilla extract, then whisk until the mixture is completely smooth, creamy, and well combined. (This creates a rich, silky custard base that will soak deeply into the thick slices of bread, resulting in that perfect tender, custardy texture in every bite.)
Using a sharp bread knife or serrated knife, slice the bread into thick slices about 1 ½ inches thick. For the best texture, aim for even slices — slightly thicker than standard sandwich bread. This thickness helps the bread soak up the rich custard without falling apart while still staying soft and creamy in the center after baking.
Arrange the thick bread slices in a single layer over the caramel mixture in the 9x13 baking dish, placing them as close together as possible.
Gently squeeze the slices together to fit them tightly — this helps maximize the number of slices and ensures every piece gets coated with the buttery caramel on the bottom.
Carefully pour the custard mixture evenly over the arranged bread slices. Pour slowly so the liquid has time to soak into the bread. Use a spoon or spatula to gently help the mixture flow between the slices and reach all the way to the bottom of the dish. (This ensures every piece of bread absorbs the rich vanilla custard for that perfect creamy texture.)
Cover the baking dish tightly with plastic wrap or aluminum foil and place it in the refrigerator overnight (at least 8 hours, or up to 24 hours). As it chills, the thick slices of bread will slowly soak up the rich vanilla custard, becoming completely saturated. This overnight rest is the secret to achieving that perfect creamy, custardy texture throughout while allowing the caramel base to set beautifully underneath.
Remove the baking dish from the refrigerator and let it sit on the counter for 20–30 minutes to take the chill off.
Meanwhile, preheat your oven to 350°F. Once the casserole has come to room temperature, bake it uncovered for 40–45 minutes, or until the top is puffed, golden brown, and the edges are lightly caramelized.
Remove the casserole from the oven and let it cool for 5–10 minutes.
Serve the warm Crème Brûlée French Toast Bake with a light dusting of powdered sugar. The powdered sugar stays bright white against the golden, crackly caramelized crust, creating a beautiful visual contrast and adding a touch of extra sweetness to every bite.
Warm your maple syrup and drizzle it generously over each portion — the syrup will mingle with the crackly sugar topping, seep into the custardy bread, and pool around the berries for an extra layer of sweetness and shine.
Garnish with fresh berries (raspberries, strawberries, and blueberries) and/or a dollop of lightly sweetened whipped cream. These bright additions not only make the dish look bakery-worthy and elegant, but they also add a refreshing pop of color and flavor that perfectly balances the rich sweetness.
A few fresh mint leaves on top can elevate the presentation even more!
