Ingredients for Overnight Croissant Breakfast Bake

Gather these items:

5 to 7 large croissants, sliced in half lengthwise
2 tablespoons unsalted butter
1 sweet onion, diced
2 garlic cloves, minced
10 ounces cremini mushrooms, chopped
8 ounces fresh baby spinach
Kosher salt and pepper, to taste
8 large eggs
2 ½ cups milk
1 cup heavy cream
8 ounces Gruyere cheese, freshly grated
Fresh chopped parsley, for topping
Parmesan cheese, for topping

How to Make Overnight Croissant Breakfast Bake Step-by-Step

Step 1: Preheat the oven to 450 degrees F. Place the croissants cut-side up on a baking sheet and bake for 5 to 8 minutes until toasty. Remove and let cool slightly, then chop or tear into pieces.
Step 2: Heat butter in a large skillet over medium-low heat. Add diced onions and minced garlic; cook for 5 minutes until softened. Add chopped mushrooms and cook for another 5 minutes until plump and juicy. Stir in the baby spinach and cook until wilted. Season with kosher salt and pepper.
Step 3: Brush a 9×13 inch baking dish with melted butter. Combine croissant pieces and sautéed vegetable mixture in the dish, tossing well to combine.
Step 4: In a large bowl, whisk together eggs, milk, heavy cream, and a large pinch of salt and pepper. Stir in 1 cup of grated Gruyere cheese and optionally some fresh chopped herbs like parsley or chives.
Step 5: Pour the egg mixture over the croissant and vegetable mixture in the baking dish. Press the croissants gently into the egg liquid to ensure they absorb it. Cover the dish with plastic wrap and refrigerate for 8 hours or overnight.
Step 6: Preheat the oven to 350 degrees F. Remove the dish from the fridge 30 minutes before baking to take off the chill. Remove plastic wrap, top the casserole with the remaining grated Gruyere cheese, and bake uncovered for 45 minutes until set and golden.
Step 7: Sprinkle extra Parmesan cheese and fresh chopped parsley on top before serving. Enjoy warm for breakfast or brunch!
