Choosing the right ingredients is what makes this casserole truly shine. I always recommend fresh, flaky croissants — day-old ones work perfectly because they soak up the custard better without turning mushy. For the custard, I stick to simple, quality basics like whole milk and eggs, plus a touch of vanilla to keep things fragrant and comforting. When I’m feeling playful, I add a sprinkle of cinnamon or nutmeg to bring out those warm flavors that make this dish feel like a hug from the inside.

  • 6 large croissants (preferably day-old), cut into 2-inch pieces
  • 4 large eggs
  • 2 cups whole milk (or half-and-half for extra richness)
  • 1/2 cup granulated sugar
  • 1 tablespoon vanilla extract
  • 1 teaspoon ground cinnamon (optional)
  • Pinch of salt
  • Powdered sugar, for garnish (optional)
  • Fresh berries or sliced fruit, for serving (optional)

If you need a dairy-free option, almond or oat milk can work well, though I’d suggest reducing the sugar slightly since these alternatives can be naturally sweeter. Also, feel free to swap croissants with brioche for a similar buttery richness.

Instructions

  1. Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
  2. Cut the croissants into 2-inch pieces and spread them evenly in the prepared dish.
  3. In a large bowl, whisk together eggs, milk, sugar, vanilla extract, cinnamon (if using), and a pinch of salt until smooth and combined.
  4. Pour the custard mixture evenly over the croissant pieces, gently pressing down to ensure they soak up the liquid.
  5. Cover the dish with plastic wrap and refrigerate for at least 1 hour, or overnight for best results — this step lets the croissants absorb all the custardy goodness.
  6. Remove the casserole from the fridge about 15 minutes before baking to let it come to room temperature.
  7. Bake uncovered for 45-50 minutes, or until the top is golden brown and the custard is set (a knife inserted should come out clean).
  8. Let it cool for 10 minutes before serving. Dust with powdered sugar and add fresh berries if desired.

One little trick I’ve learned is to avoid overbaking — that’s how you keep the casserole moist and tender instead of dry. Emma always tells me the edges are her favorite part, all crispy and caramelized!
