• Mixing bowls: For preparing the custard and caramel sauce separately.

Stepwise Method: Boozy Caramel French Toast Casserole

Step 1: Prepare the caramel sauce

Start by melting 1/2 cup (1 stick) of unsalted butter in a medium saucepan over medium heat. Once melted, stir in 1/2 cup packed light brown sugar and 2 tablespoons light corn syrup. Cook, stirring frequently, until the mixture is smooth and bubbling, about 3 to 5 minutes. Remove from heat and let it cool slightly. This sauce will form the decadent caramel layer at the bottom of your casserole dish and soak into the brioche for that signature sticky sweetness.

Step 2: Assemble the base layer

Grease your 9×13-inch baking dish generously with butter to prevent sticking. Pour the warm caramel sauce into the bottom of the dish and spread it evenly. Next, cut the brioche into roughly 1-inch cubes. Place a single layer of brioche cubes on top of the caramel sauce, pressing lightly so some caramel seeps into the bread. You’ll use about half of your brioche for this layer.

Step 3: Mix the custard

In a large mixing bowl, whisk together 5 large eggs, 1 cup half-and-half, 1 teaspoon vanilla extract, 3 tablespoons Grand Marnier, 1 teaspoon orange zest, and 1/2 teaspoon salt until fully combined. The Grand Marnier and orange zest add that signature boozy citrus flavor that makes this casserole truly special.

Step 4: Layer and soak

Pour half of the custard mixture evenly over the brioche layer in the baking dish. Then, add the remaining brioche cubes on top and pour the remaining custard over the top, ensuring all the bread is soaked. Gently press the bread with a spatula to help absorb the custard. Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, preferably overnight. This allows the custard to fully soak into the bread, resulting in a custardy, tender casserole.

Step 5: Bake to golden perfection

Preheat your oven to 350°F (175°C). Remove the plastic wrap and bake the casserole uncovered for 45 to 55 minutes, or until the top is golden brown and the custard is set when you gently shake the dish. If the top starts to brown too quickly, tent it loosely with foil.

Step 6: Serve and enjoy

Let the casserole cool for 10 minutes before slicing. Serve warm with a drizzle of maple syrup, fresh fruit, or a dusting of powdered sugar. For an extra indulgence, try it alongside some Caramel Drizzle Cheesecake Bars With Pretzel Crust for a dessert-inspired brunch.

Make It Fit Your Plan

• Make it dairy-free: Substitute half-and-half with a creamy almond or oat milk alternative.
• Adjust sweetness: Use less brown sugar or skip the corn syrup if you prefer a less sweet casserole.
• Add texture: Fold in chopped pecans or walnuts for a delightful crunch.
• Fruit additions: Layer sliced apples or berries between the brioche layers for extra flavor and moisture.
• Non-alcoholic version: Replace Grand Marnier with an orange extract or orange juice concentrate.

Notes on Ingredients

• Brioche Bread: The richness and buttery texture of brioche make it ideal for soaking up the custard and caramel. If you can’t find brioche, a thick, soft white bread works too, but the flavor will be less decadent.
• Unsalted Butter: Using unsalted butter allows you to control the salt content more precisely and enhances the caramel flavor.
• Light Brown Sugar: Adds a deep caramel flavor and moisture. Avoid dark brown sugar as it may overpower the dish.
• Light Corn Syrup: Helps keep the caramel sauce smooth and prevents crystallization.
• Half-and-Half: Provides a creamy custard base. Whole milk can be used as a substitute for a lighter option.
• Grand Marnier: This orange-flavored liqueur is crucial for the boozy citrus note but can be replaced with orange juice or extract if preferred.
• Orange Zest: Fresh zest is essential for bright, natural citrus flavor.

Storing Tips & Timelines

Once baked, store any leftover Boozy Caramel French Toast Casserole covered in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire casserole in a 325°F oven until heated through.

If you want to prepare in advance, assemble the casserole up to 24 hours before baking and keep it refrigerated. This makes it perfect for busy mornings or holiday brunches.

Your Questions, Answered

Can I use a different type of bread?

Absolutely! While brioche is preferred for its buttery texture and flavor, you can use challah or even a sturdy white sandwich bread. Just ensure the bread is thick and fresh or slightly stale to absorb the custard well.

What can I substitute for Grand Marnier?

If you’d rather avoid alcohol, substitute Grand Marnier with orange juice concentrate or a teaspoon of orange extract to maintain the citrus flavor without the boozy kick.

Can I make this casserole vegan?

This recipe relies on eggs, butter, and half-and-half for its custard and caramel. To make a vegan version, you’d need several substitutions like plant-based butter, a flaxseed or chia egg alternative, and coconut cream. However, the texture and flavor will differ from the original.

How do I prevent the casserole from getting soggy?

Using sturdy bread like brioche helps prevent sogginess. Also, make sure to soak the bread evenly but not overly saturate it. Baking uncovered allows excess moisture to evaporate, resulting in a crisp top layer.
