Baked Brioche French Toast Squares – Easy Breakfast Casserole

Hi there, food lover! 👋 Ready to indulge in a warm, cozy breakfast that feels like a hug on a plate? This traditional-style Baked Brioche French Toast Squares recipe brings together pillowy brioche, fragrant spices, and a creamy custard to create a casserole that’s perfect for slow mornings and bustling brunches alike.

This dish is inspired by the timeless French toast breakfasts shared around family tables for generations. Using brioche—rich, buttery, and slightly sweet—adds a luxurious touch that transforms an everyday breakfast into something special. As it bakes, the bread soaks up the custard, turning perfectly soft inside while the top becomes beautifully golden.

Whether you’re hosting brunch, prepping ahead for busy mornings, or simply craving something that warms the heart, this casserole delivers comfort in every bite. It’s simple, satisfying, and wonderfully nostalgic—just like the recipes passed down from grandma’s kitchen.

Let’s dive in and bake something deliciously memorable together. 🍞🥚✨

Ingredients

🍞 Main Ingredients

• 1 large loaf brioche bread, cut into 1 ½-inch cubes
• 6 large eggs
• 2 cups whole milk
• ½ cup heavy cream
• ½ cup granulated sugar
• 2 tbsp brown sugar
• 2 tsp vanilla extract
• 1 tsp ground cinnamon
• ¼ tsp nutmeg
• Pinch of salt

🍯 Toppings (optional but lovely!)

• Powdered sugar
• Maple syrup
• Fresh berries
• Whipped cream

Step-by-Step Directions

1. Prepare your baking dish
   Grease a 9×13-inch baking dish with butter. Add the brioche cubes evenly across the dish.
2. Make the custard
   In a large bowl, whisk the eggs, milk, cream, sugars, vanilla, cinnamon, nutmeg, and salt until smooth.
3. Combine bread and custard
   Pour the custard evenly over the brioche cubes, pressing lightly so every piece soaks up the mixture. Cover and refrigerate for at least 30 minutes or overnight for deeper flavor.
4. Preheat & bake
   Preheat oven to 350°F (175°C). Bake uncovered for 40–45 minutes, or until the top is golden and the center is set.

   Let the casserole cool for 10 minutes before cutting into squares.
6. Serve & enjoy
   Dust with powdered sugar and drizzle with maple syrup. Add berries or whipped cream for a beautiful finish. 🍓✨
