Ingredients
  

For the Casserole
  • 6 large croissants torn into pieces
  • 6 large eggs
  • 2 cups milk whole milk works best
  • 1 cup heavy cream
  • 1/2 cup granulated sugar
  • 1 tbsp vanilla extract
  • 1 tsp ground cinnamon
  • 1/4 tsp salt
  • 1/2 cup maple syrup optional, for serving
  • Powdered sugar optional, for serving

Equipment

  • 9x13 inch Baking Dish
  • Large Mixing Bowl
  • Whisk
  • Plastic wrap

Method
 

  1. Step 1: Start by greasing a 9x13-inch baking dish. Layer the torn croissant pieces evenly in the dish.
  2. Step 2: In a large mixing bowl, whisk together the eggs, milk, heavy cream, granulated sugar, vanilla extract, cinnamon, and salt until everything is well combined.
  3. Step 3: Pour the egg mixture over the croissant pieces, ensuring they are fully coated. Press down gently to submerge any floating pieces.
  4. Step 4: Cover the dish with plastic wrap and refrigerate overnight.
  5. Step 5: When you're ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and let it sit at room temperature for about 15 minutes.
  6. Step 6: Bake uncovered for 35-40 minutes, or until the top is golden brown and the center is set.
  7. Step 7: Serve warm, drizzled with maple syrup and dusted with powdered sugar if desired.

Notes

Make sure to press down on the croissants after pouring the egg mixture to ensure they soak up all that delicious custard. If you have leftovers, let the casserole cool completely, then cover it tightly and store it in the refrigerator for up to 3 days.
