Ingredients

Gather these simple ingredients to create your irresistible croissant breakfast casserole:

• 6 Croissants
• 8 slices cooked Bacon; finely chopped
• 8 Eggs
• 1 tsp Parsley
• 1 tsp Onion Powder
• 1 Tbsp Chives; chopped
• 1 tsp Garlic Powder
• 1/2 tsp Salt
• 1/2 tsp freshly ground Black Pepper
• 2 ¾ cups Milk
• 1 cup heavy Cream
• 1 cup Colby Jack; shredded (divided)
• 1 cup smoked Gouda; shredded (divided)

Notes & Substitutions

You can easily adapt this casserole with a few simple tweaks. Fresh croissants work wonderfully, but day-old ones absorb the egg mixture even better. You can also use frozen pre-baked croissants; simply thaw them completely before slicing.

Swap the bacon for finely diced ham or cooked breakfast sausage to change the savory profile. Feel free to use fresh herbs like finely chopped fresh parsley or chives instead of dried ones for a brighter flavor. For the best rich, soufflé-like texture, avoid substituting the heavy cream with lighter milk options. You can also experiment with other shredded cheeses like sharp cheddar, mozzarella, Swiss, or Monterey Jack to match your preference.

Equipment

You won’t need many specialized tools for this easy casserole. Here’s what you need:

• Baking sheet
• Parchment paper
• 9×13 inch baking dish
• Large mixing bowl
• Whisk
• Spatula

Instructions

Creating this delightful croissant breakfast casserole is straightforward. Follow these steps for a perfect result every time:

1. Prep Oven and Dish: Preheat your oven to 425 degrees F. Line a baking sheet with parchment paper and generously grease a 9 x 13 inch baking dish with butter.
2. Slice Croissants: Slice each croissant into four pieces. Arrange the sliced croissants in a single layer on the parchment-lined baking sheet.
3. Toast Croissants: Toast the croissant pieces in the preheated oven for 5 minutes. You want them dried slightly, not overly golden or crisp. This step prevents your casserole from becoming soggy.
4. Reduce Oven Heat: Lower the oven temperature to 350 degrees F.
5. Layer Base: Carefully transfer the toasted croissant quarters from the baking sheet to the prepared baking dish, distributing them evenly. Scatter the finely chopped cooked bacon over the croissants.
6. Prepare Egg Mixture: In a large mixing bowl, whisk together the eggs, parsley, onion powder, garlic powder, dried chives, salt, black pepper, milk, and heavy cream until well combined.
7. Add Cheese to Eggs: Stir ¾ cup of the shredded Colby Jack cheese and ¾ cup of the shredded smoked Gouda cheese directly into the egg mixture. Mix thoroughly to distribute the cheese.
8. Assemble Casserole: Pour the prepared egg and cheese mixture evenly over the croissants and bacon in the baking dish.
9. Soak Croissants: Use a spatula or the back of a spoon to gently press down on the croissant pieces. This helps them absorb the egg mixture, ensuring a moist and flavorful casserole.
10. Top with Remaining Cheese: Sprinkle the remaining ¼ cup of Colby Jack and ¼ cup of smoked Gouda evenly over the entire surface of the casserole. This creates a beautiful, cheesy crust.
11. Bake Casserole: Place the baking dish in the preheated 350°F oven. Bake for 40-45 minutes, or until the top is golden brown, and the egg mixture is set. A knife inserted near the center should come out clean.
12. Serve Immediately: Remove the delicious croissant breakfast casserole from the oven and serve it hot. Let it rest for a few minutes before slicing and enjoying.

Pro Tips & Troubleshooting

Ensure your croissant breakfast casserole turns out perfectly every time with these helpful hints.

• Prevent Soggy Croissants: Toasting the croissant pieces before assembly is crucial. This step dries them out slightly, allowing them to absorb the egg mixture without becoming mushy. Understanding the culinary science behind preventing soggy bread in dishes like French toast and breakfast casseroles can elevate your cooking.
• Achieve a Fluffy Texture: Do not reduce the amount of heavy cream. It contributes to the rich flavor and the light, soufflé-like consistency. For a richer flavor and light consistency, incorporating heavy cream helps move egg proteins further apart, resulting in creamier, fluffier eggs.
• Ensure Even Baking: Rotate the casserole dish halfway through the baking time. This helps achieve uniform browning and even cooking.
• Check for Doneness: To verify the casserole is fully cooked, insert a thin knife or a wooden skewer into the center. If it comes out clean with no liquid egg, your casserole is ready.
• Avoid Overcooking: Baking for too long can result in rubbery eggs. Watch it closely after the 40-minute mark.
• Cool Slightly Before Slicing: Let the casserole rest for 5-10 minutes after removing it from the oven. This allows the internal structure to set, making it easier to slice cleanly.

Serving, Storage, & Variations

This versatile croissant breakfast casserole adapts beautifully to your needs.

Serving Suggestions

• Serve individual portions alongside a vibrant fresh fruit salad for a balanced meal.
• Offer extra breakfast meats like crispy sausage links or Canadian bacon on the side.
• Garnish the top with a sprinkle of fresh chopped chives or parsley right before serving for added color and freshness.

Make Ahead & Storage

• Make Ahead: Assemble the entire casserole, excluding the final cheese topping, the night before. Cover the dish tightly with plastic wrap and refrigerate overnight. In the morning, remove from the fridge 30 minutes before baking, then sprinkle with the remaining cheese and bake as directed, adding an extra 5-10 minutes to the baking time if needed.
• Reheating Leftovers: Reheat individual slices in an air fryer at 300°F for 5-7 minutes, or in the microwave until warmed through.
• Storage: Store any leftover croissant breakfast casserole in an airtight container in the refrigerator for up to 3 days.

Croissant Breakfast Casserole Variations

• Spicy: Add a pinch of chili powder, red pepper flakes, or a dash of your favorite hot sauce to the egg mixture.
• Florentine: Incorporate 1 cup of thawed, squeezed-dry chopped spinach, cooked Italian sausage, and sautéed mushrooms.
• Spanish: Use crumbled cooked chorizo sausage, diced roasted red peppers, and replace Colby Jack with shredded Manchego cheese.
• Coastal: Gently fold in flaked smoked salmon, fresh dill, and use a blend of mild white cheeses like mozzarella and Monterey Jack.
• Sweet French Toast: Omit all savory ingredients. Add a teaspoon of vanilla extract and lemon zest to the egg mixture. Top with cream cheese dollops, mixed berries, and dust with powdered sugar after baking.

FAQ

• Can I freeze this casserole? Freezing is not recommended for the fully baked croissant breakfast casserole as the texture of the eggs and croissants can change upon thawing.
