Chocolate Croissant Overnight Breakfast Casserole

This Chocolate Croissant Overnight Breakfast Casserole is the make-ahead magic your weekend brunch needs—flaky, buttery croissants soaked in a rich custard with melty pockets of chocolate in every bite.  It couldn’t be easier which is absolutely key for winter weekend baking!

I suspect we don’t give grocery store croissants enough credit. Sure, they’re more soft than shattery, definitely more pillowy than crisp, but that just makes them perfectly toastable and downright re-workable, right? A fancy bakery croissant demands to be eaten fresh, preferably with a strong coffee and an air of sophistication. But the humble grocery store croissant? It’s here for the long haul. It’s ready to be split, buttered, griddled, or—in the case of this Chocolate Croissant Overnight Breakfast Casserole—soaked in custard and sprinkled with chocolate!

This is the kind of breakfast that embraces slow and simple. A little prep the night before, a lazy bake in the morning, and suddenly, you’re the person serving warm, chocolate-laced croissant casserole with your second cup of coffee.  A late morning hero, some might say. And really, what more could we ask of this very cold February?

Now, here’s how to make this very alluring breakfast bake.  It really is more than just the sum of its parts. This is very much a follow-your-heart recipe. Details to follow.

Lightly butter a 10-inch cast iron skillet (or whatever pan you have handy) and set it aside. Take those grocery store croissants—split them in half and tuck them into the pan in a way that feels right to you. No need for perfection here. Scatter most of the mini chocolate chips between the layers, saving a small handful for a last-minute sprinkle before baking. In a bowl, whisk together eggs, milk, and cream until smooth, then add in the maple syrup, vanilla, cinnamon, and a pinch of salt. (The cinnamon will clump. That’s just life.) Pour the custard over the croissants, pressing everything down gently so it soaks up all the goodness. Cover and refrigerate overnight—this is where the magic happens. In the morning, preheat the oven to 350°F, top with the remaining chocolate chips, and bake until golden and crisp, about 45-50 minutes. Let it cool slightly before serving warm with soft whipped cream and a drizzle of maple syrup. Then, sit back and enjoy your slow and simple morning, croissant casserole in hand.

Description

If you’re looking for an easy and indulgent overnight breakfast casserole, this one bakes up golden and custardy, perfect for slow mornings and second cups of coffee.


Ingredients

Scale
  • A pat of unsalted butter, for greasing the pan
  • 45 large croissants, stale and cut in half
  • 1 cup mini chocolate chips (about half of a 10-ounce bag), divided
  • 4 large eggs
  • 1 ½ cups whole milk
  • ½ cup heavy cream
  • 2 tablespoons maple syrup
  • 2 teaspoons vanilla extract
  • ½ teaspoon ground cinnamon
  • ½ teaspoon kosher salt
  • Lightly sweetened whipped cream and maple syrup for topping

Instructions

  1. Lightly grease a 10-inch cast iron skillet with butter and set aside. (A 9×9-inch square or round cake pan will also work here!)
  2. Arrange croissant halves in a fan pattern around the pan. Don’t put too much pressure on yourself with this step. Just tuck as many croissant parts in as best you can. Sprinkle all but about ¼ cup of the mini chocolate chips between the croissant pieces, spreading so just about every bite has a bit of chocolate. Save the remaining ¼ cup of mini chips for the top, just before baking.
  3. In a medium bowl, whisk together eggs, milk, and cream until the eggs are fully incorporated into the dairy. Whisk in the maple and vanilla. Sprinkle the cinnamon and salt overtop and whisk until well combined. It’s ok if the cinnamon is clumpy. That’s just a fact of life.
  4. Slowly pour the mixture over the prepared chocolate croissants in the pan. It’s ok if not all parts of the croissants are covered. Press so everything is moistened. Cover with plastic wrap and refrigerate overnight.
  5. When ready to bake, place a rack in the center of the oven and preheat oven to 350 degrees F. Uncover the dish, sprinkle with the remaining chocolate chips and bake until the tops of the croissants are golden and crisp, about 45-50 minutes.
  6. Remove from the oven and allow to cool for 15 minutes before serving warm with soft whipped cream and a drizzle of maple syrup.

Questions

  1. This sounds so delicious but I do have a question. Do you use plain croissants from the grocery store or chocolate croissants?

  2. This is very similar to the croissant bread pudding I used to make when I baked for a coffee shop many years ago… it was the perfect way to use up leftover croissants, and customers loved it!

  3. When you say “cut in half”, do you mean cut vertically through the middle so it divides into two hooks, or sliced horizontally through the center like you’re making a sandwich? Or it doesn’t matter?
