Build Overnight Croissant Breakfast Bake. Step by Step
Step 1: Prepare the Croissants
Start by slicing the croissants in half lengthwise. This will create a lovely base for your casserole. Lay them cut-side up in a greased 9×13-inch baking dish, ensuring they are evenly spread out.
Step 2: Sauté the Vegetables
In a skillet, melt the unsalted butter over medium heat. Add the diced sweet onion and sauté until translucent, about 5 minutes. Stir in the minced garlic and chopped cremini mushrooms, cooking until the mushrooms are tender. Add the fresh baby spinach and cook just until wilted. Season with kosher salt and pepper to taste.
Step 3: Assemble the Casserole
Evenly distribute the sautéed vegetable mixture over the cut croissants in the baking dish. Sprinkle half of the grated Gruyere cheese on top of the vegetables.
Step 4: Prepare the Custard
In a mixing bowl, whisk together the eggs, milk, heavy cream, and a pinch of salt and pepper until well combined. Pour this creamy mixture evenly over the croissants and vegetables, allowing it to soak in.
Step 5: Add Remaining Cheese
Sprinkle the remaining Gruyere cheese over the top of the casserole. Cover the dish with plastic wrap or foil and refrigerate overnight. This allows the flavors to meld together beautifully.
Step 6: Bake
In the morning, preheat your oven to 350°F (175°C). Remove the cover from the baking dish and bake the casserole for 45 to 55 minutes, or until it is puffed and golden brown on top. If it browns too quickly, you can cover it loosely with foil.
Step 7: Garnish and Serve
Once baked, remove the casserole from the oven and let it cool for about 10 minutes. Garnish with fresh chopped parsley and a sprinkle of Parmesan cheese before serving. Cut into squares and enjoy your Overnight Croissant Breakfast Bake with a side of fresh fruit or a light salad.
Season-by-Season Upgrades

- Summer: Incorporate zucchini, bell peppers, and tomatoes for a colorful, garden-fresh twist.
