Ingredients Overview

The recipe divides into two components: the French toast base and the sweet topping.

French Toast Base

• 24 ounces (680 g) stale brioche bread: Provides a soft, buttery base. French, Challah, or Texas toast work as substitutes. Stale bread soaks up the custard better.
• ½ cup (50 g) chopped pecans, optional: Adds texture and nutty flavor.
• 8 large eggs: Essential for creating a rich custard.
• 3 cups (732 g) whole milk: Creates a creamy texture and tender custard.
• ¼ cup (81 g) real maple syrup: Adds sweetness and depth of flavor.
• 1 tablespoon pure vanilla extract: Enhances the aroma and overall flavor.
• 1 teaspoon salt: Balances the sweetness.
• 2 teaspoons ground cinnamon & ½ teaspoon ground nutmeg: Adds warm, comforting spice.

Topping

• ½ cup (114 g) butter, sliced: Melts into the brown sugar, creating a sticky, caramel-like top.
• ½ cup (110 g) packed brown sugar, light or dark: Adds sweetness and helps the topping caramelize.
• 1 teaspoon ground cinnamon: Enhances the topping with warm, aromatic spice.

Preparation Method

Follow these steps to create a rich, custardy French toast casserole with minimal hands-on time.

Step One: Prepare the Bread

Cut the brioche (or chosen bread) into roughly 1-inch cubes. If using stale bread, it will soak up the custard mixture better without becoming mushy. Place the bread cubes evenly in your slow cooker and sprinkle the optional chopped pecans over the top.

Step Two: Mix the Custard

In a large bowl, whisk together the eggs, milk, maple syrup, vanilla extract, salt, cinnamon, and nutmeg until smooth and fully combined. Pour the custard evenly over the bread cubes in the slow cooker, pressing lightly with a spatula to ensure all pieces are soaked.

Step Three: Prepare the Topping

In a small bowl, mix the sliced butter, brown sugar, and cinnamon. Evenly distribute this mixture over the custard-soaked bread.

Step Four: Cook the Casserole

Cover the slow cooker with its lid and cook on low for 6–7 hours or high for 3–4 hours. The casserole is done when the custard is set and a knife inserted in the center comes out clean. Avoid lifting the lid during cooking to maintain a consistent temperature.

Step Five: Serve

Once cooked, allow the casserole to rest for 10–15 minutes before serving. This helps it set further and makes it easier to cut portions. Serve warm, optionally with extra maple syrup, fresh fruit, or a dollop of whipped cream.

Texture and Flavor Notes

This casserole has a tender, custardy interior from the egg and milk mixture, while the brown sugar and butter topping creates a slightly sticky, caramelized surface. The warm spices of cinnamon and nutmeg complement the sweetness of maple syrup and bread. The optional pecans add crunch, creating a delightful contrast with the soft custard.

Tips for Best Results

• Use stale bread to ensure the custard absorbs properly without turning mushy.
• Layer the butter and brown sugar evenly for consistent caramelization.
• Do not lift the lid during cooking to maintain a steady temperature.
• If your slow cooker runs hot, check the casserole 30 minutes before the end of cooking to avoid overcooking.

Serving Suggestions

Serve this French toast casserole for breakfast, brunch, or even dessert. Pair it with fresh berries, whipped cream, or a drizzle of extra maple syrup. It’s perfect for holiday mornings or feeding a crowd.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave for 30–60 seconds or warm the entire casserole in the slow cooker on low for 20–30 minutes.

Make-Ahead Convenience

You can assemble the casserole the night before, cover, and refrigerate overnight. In the morning, simply cook according to the instructions. This is ideal for busy mornings or when hosting brunch.
