Ingredients

For this Overnight Croissant Breakfast Bake, you’ll need the following ingredients to create a mouthwatering breakfast casserole:

• Croissants: The star of the dish, providing a buttery, flaky texture that soaks up all the rich flavors.
• Unsalted Butter: Adds extra richness to the croissants when toasted, enhancing the overall flavor.
• Sweet Onion: Adds a savory base to the bake, complementing the richness of the croissants.
• Garlic: For a fragrant kick that balances the creamy cheese and vegetables.
• Cremini Mushrooms: These plump, juicy mushrooms lend a wonderful earthy flavor to the bake.
• Fresh Baby Spinach: Adds color, nutrition, and a slight bitterness that pairs beautifully with the richness of the other ingredients.
• Kosher Salt & Pepper: Basic seasonings that bring out the flavors of all the ingredients.
• Eggs: The key ingredient that binds everything together, creating a custard-like texture when baked.
• Milk & Heavy Cream: Add richness and creaminess, giving the bake its smooth texture.
• Gruyere Cheese: The best cheese for this recipe, it melts beautifully and adds a savory, slightly nutty flavor.
• Fresh Parsley: For a pop of color and freshness to finish the dish.
• Parmesan Cheese: A sprinkle on top adds a salty, cheesy finish that takes this bake to the next level.

Alternative Ingredient Suggestions

• Vegetarian Sausage or Bacon: If you miss the savory flavor of sausage, you can swap it for plant-based sausage or crispy bacon bits.
• Different Cheeses: Gruyere can be swapped with Swiss cheese, cheddar, or even mozzarella for a milder flavor.
• Add More Greens: You can increase the amount of spinach or add kale, Swiss chard, or arugula for a nutrient-packed twist.
• Dairy-Free Option: Use non-dairy milk, cream, and vegan cheese for a dairy-free version.

Step-by-Step Instructions

1. Toast the Croissants: Preheat your oven to 450°F. Place the croissants cut-side up on a baking sheet and toast for 5 to 8 minutes, until golden brown. Remove from the oven and let them cool slightly before tearing or chopping them into pieces.
2. Sauté the Vegetables: In a large skillet, melt the butter over medium-low heat. Add the diced onion and minced garlic, cooking for 5 minutes until soft and fragrant. Add the chopped mushrooms and cook for another 5 minutes until plump and juicy. Stir in the spinach until wilted, then season with salt and pepper.
3. Assemble the Bake: Butter a 9×13-inch baking dish. Combine the toasted croissant pieces and the sautéed vegetables in the dish, tossing well to combine.
4. Make the Egg Mixture: In a large bowl, whisk together the eggs, milk, heavy cream, salt, and pepper. Stir in 1 cup of grated gruyere cheese. (You can also add chopped fresh herbs like parsley or chives for extra flavor.) Pour the egg mixture over the croissant mixture, making sure all the pieces are soaked.
5. Chill Overnight: Cover the baking dish with plastic wrap and refrigerate for at least 8 hours or overnight. This step allows the croissants to fully absorb the egg mixture, creating a decadent custard.
6. Bake: The next morning, preheat your oven to 350°F. Remove the dish from the fridge and let it sit for 30 minutes to come to room temperature. Remove the plastic wrap, top with the remaining grated gruyere cheese, and bake uncovered for 45 minutes, or until the top is golden and bubbly.
7. Serve: Garnish with a sprinkle of parmesan cheese and fresh parsley before serving. This dish is best enjoyed warm and is perfect for a family breakfast or special occasion.

Tips & Tricks

• Don’t Skip Toasting the Croissants: Toasting the croissants before assembling the dish brings out caramelized, crispy bits that add incredible texture and flavor to the bake. It’s essential for achieving the perfect outcome.
• Make-Ahead: This recipe is meant to be prepared the night before, making it ideal for busy mornings or hosting a crowd.
• Adjust the Cheese: Gruyere is a must for its meltiness and flavor, but feel free to add parmesan, cheddar, or even a sharp blue cheese for variation.
• Avoid Overbaking: Keep an eye on the bake to ensure it doesn’t dry out. The edges should be golden brown, but the inside should remain moist and custardy.

Pairing Ideas and Variations

This Overnight Croissant Breakfast Bake is rich and filling on its own, but you can enhance the meal with a few side dishes:

• Fresh Fruit: Pair the bake with fresh berries, citrus, or a fruit salad to add a refreshing contrast.
• Crispy Bacon or Sausage: If you love a hearty breakfast, add crispy bacon or sausage on the side for extra protein.
• Salads: A light mixed green salad with a tangy vinaigrette will balance the richness of the croissant bake.

For a gluten-free version, substitute the croissants with gluten-free bread and ensure that all the other ingredients are gluten-free.
