Crème Brûlée French Toast Casserole
What’s better than waking up to a house full of guests and a no-fuss breakfast ready to bake? This lightened-up version of crème brûlée French toast was adapted from a reader request and has become a family favorite for holiday mornings. It captures the rich flavors of the dessert—vanilla, cinnamon and a caramelized sugar note—while using lighter dairy choices to reduce calories. It works perfectly for Christmas morning, brunch gatherings, or any time you need a make-ahead breakfast casserole to feed a crowd.
Why You’ll Love This Recipe
The original version used butter and more cream. To lighten the recipe while preserving that rich crème brûlée character, this version removes the butter, swaps some half-and-half for 1% milk, and uses a lower-calorie brown sweetener option. The result remains indulgent, with a custardy interior and an appealing caramel note.
- Make-ahead friendly: The casserole benefits from resting overnight, so it’s excellent to prepare the night before.
- Feeds a crowd: Easily doubled to make two 13 x 9-inch casseroles for larger gatherings.
- Flexible diet options: Vegetarian, can be made gluten-free when using gluten-free bread, and adaptable for lower-calorie choices.
Ingredients You’ll Need
Below are the main ingredients. Scroll to the recipe section for exact measurements and the complete recipe card.
- Brown sugar: Used to make a simple syrup that flavors the casserole. A brown monk-fruit sweetener can be used as a lower-sugar alternative.
- Water: Combined with the brown sugar to form a syrup.
- Challah bread: A soft, slightly sweet braided bread that soaks up the custard beautifully.
- Eggs: Create the custardy base that binds the bread.
- Dairy: A mix of 1% milk and half-and-half gives a creamy texture without too many calories.
- Rum (optional): A teaspoon of Myers’s or another dark rum adds depth, but it is optional.
- Flavorings: Vanilla extract and ground cinnamon for warm, classic flavor.
- Kosher salt: Balances and enhances the sweetness.
- Powdered sugar: A light dusting before serving (optional).
How to Make a Crème Brûlée French Toast Bake
This simple make-ahead casserole requires minimal hands-on time. Follow these steps and use the recipe card below for precise measurements and timing.
- Make the simple syrup: Gently melt the brown sugar with water in a small skillet over low heat until smooth. Reserve half for the custard and pour the other half into a 13 x 9-inch baking dish coated with cooking spray or lightly greased.
- Layer the bread: Arrange cubed challah in a single layer in the baking dish, pressing the pieces gently so they fit evenly.
- Prepare the custard: In a large bowl whisk together the eggs, remaining sugar mixture, milk, half-and-half, vanilla, rum (if using), cinnamon, and salt. Pour the custard evenly over the bread, pressing down lightly so the bread soaks up the liquid.
- Chill overnight: Cover and refrigerate at least 8 hours or overnight to allow the bread to absorb the custard.
- Bake: Bring the casserole to room temperature while you preheat the oven to 350°F. Bake uncovered on the middle rack until puffed and edges are lightly golden, about 45 to 55 minutes. Let rest 5 to 10 minutes before serving.
- Finish and serve: Dust with powdered sugar and a sprinkle of cinnamon. Serve warm, optionally with fresh berries, sliced bananas, or a dollop of whipped cream.
Variations
- Bread: Swap challah for brioche, French bread or a round country loaf.
- Gluten-free: Use gluten-free bread to make the casserole safe for gluten-free diets.
- Dairy: Substitute skim milk, 2% milk, or unsweetened almond milk for lighter or dairy-free options.
- Toppings: Omit powdered sugar if you prefer, or top with fresh fruit, sliced bananas, or whipped cream for added decadence.
What to Serve With Crème Brûlée French Toast
For a balanced brunch spread, include both sweet and savory options: sheet pan pancakes, a sausage and cheese egg bake, or a vegetable-and-feta breakfast casserole complement this sweet main dish. A platter of fresh fruit also pairs nicely and brightens the table.
FAQ
Overnight refrigeration produces the best texture and flavor because the bread fully absorbs the custard. If you’re short on time, refrigerate for at least 8 hours; skipping the chill will result in a less evenly soaked, drier casserole.
Storage
- Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 4 days.
- Reheat: Warm slices in the microwave or reheat in the oven until heated through.
- Freeze: After baking and cooling, slice into portions, wrap tightly with foil or plastic wrap, and freeze up to 3 months. Thaw in the refrigerator and reheat in the microwave.
