Flaky Croissant French Toast Casserole with Brown Sugar Pecans Tips, FAQ & printable recipe

Tips for success

For the best texture, use croissants that are a day or two old—they’ll hold up better to the custard. If you only have fresh ones, tear them and let them sit on a baking sheet for an hour to dry out slightly.

This prevents the final dish from becoming overly soft. Also, don’t be shy with the butter on the baking dish; it adds flavor and helps create a golden crust.

When measuring the brown sugar, pack it firmly into the measuring spoon to ensure the right sweetness. The pecan topping can be made ahead and stored in an airtight container for up to 3 days.

If the topping starts to brown too quickly during baking, cover the dish loosely with foil for the last 5 minutes. This protects the pecans from burning while allowing the custard to finish cooking.

Variations

• Chocolate-Hazelnut: Spread a thin layer of chocolate-hazelnut spread between the croissant halves before adding the custard. Omit the pecans and sprinkle with chopped hazelnuts instead. Serve with a dusting of powdered sugar.
• Apple-Cinnamon: Add 1 cup of diced apples and 1 teaspoon of ground cinnamon to the custard before pouring over the croissants. Replace the pecans with sliced almonds and add a pinch of nutmeg to the topping.
• Savory-Sweet: Reduce the maple syrup in the custard to 1 tablespoon and add 1 teaspoon of vanilla extract. Top with a mix of pecans and crispy bacon bits. Serve with a drizzle of honey instead of maple syrup.
• Orange-Blueberry: Add the zest of one orange and 1 cup of fresh blueberries to the custard. Use orange juice in place of the maple syrup in the custard. Top with toasted almonds and a light dusting of confectioners' sugar.

Storage and make-ahead

Fridge

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or oven until warmed through.

Freezer

The baked casserole can be frozen for up to 2 months. Wrap tightly in plastic wrap and then foil. Thaw overnight in the refrigerator before reheating.

Reheat

Reheat thawed or refrigerated casserole in a 350°F (175°C) oven for 15-20 minutes, or microwave individual portions for 1-2 minutes.

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for 30-60 seconds, or warm the entire dish in a 350°F (175°C) oven for 10-15 minutes. The topping will soften slightly upon reheating but will still be delicious.

Assemble the casserole up to 24 hours in advance, cover tightly with plastic wrap, and refrigerate. When ready to bake, let it sit at room temperature for 30 minutes, then bake as directed.

You may need to add 5-10 minutes to the baking time if the dish is cold. The pecan topping can also be prepared ahead and stored separately.

Serving ideas

Serve this casserole warm, straight from the oven, with a generous drizzle of bourbon maple syrup. The syrup soaks into the crisp edges and soft centers, adding another layer of sweetness.

For a pretty presentation, dust with powdered sugar and add a few fresh berries on the side—though the video keeps it simple, the casserole is plenty rich on its own.

This dish pairs beautifully with fresh fruit, crispy bacon, or a simple green salad to balance the richness. It’s also wonderful for brunch buffets—just keep it warm in a slow cooker on low for up to 2 hours. Leftovers make a decadent dessert when warmed and topped with a scoop of vanilla ice cream.

Flaky Croissant French Toast Casserole with Brown Sugar Pecans

Prep 15 minCook 25 minRest 10 minTotal 50 minServes 6

Ingredients

• 1 tbsp unsalted butter, softened
• 6 day-old flaky butter croissants
• 4 large eggs
• 1 cup heavy cream
• 2 tbsp pure maple syrup
• 3/4 cup chopped pecans
• 3 tbsp packed light brown sugar
• 2 tbsp unsalted butter, melted
• warm bourbon maple syrup, for serving

Instructions

1. Heat the oven to 375°F (190°C). Butter a 9x9-inch ceramic baking dish with the softened butter. Tear the croissants into halves and arrange them in the prepared dish, cut sides facing up. In a large bowl, whisk the eggs, heavy cream, and maple syrup until fully combined and slightly frothy.
2. Pour the custard evenly over the torn croissants, making sure every piece gets coated. Gently press the croissants down with a spatula to help them soak up the liquid. Let the mixture sit for 10 minutes at room temperature so the bread absorbs the custard fully.
3. In a small bowl, stir together the chopped pecans, brown sugar, and melted butter until the pecans are evenly coated. The mixture should be crumbly and slightly clumpy.
4. Sprinkle the pecan topping evenly over the soaked croissants. Place the dish in the oven and bake for 25 minutes, until the top is golden brown and puffed, and the custard is set in the center. The internal temperature of the custard should reach 160°F (71°C) to ensure the eggs are fully cooked.
5. Remove the casserole from the oven and let it rest for 5 minutes. This allows the custard to set further and makes slicing easier. Drizzle warm bourbon maple syrup over the top just before serving.
