Step‑by‑Step Instructions for Croissant Breakfast Casserole
Step 1: Brown the Sausage and Vegetables
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 pound of breakfast sausage, cooking until browned, about 5-7 minutes. Then, stir in 1/2 diced yellow onion and 1 diced red bell pepper, sautéing until the vegetables are soft and translucent, about 3-4 minutes. Remove from heat and let cool slightly while you prepare the filling.
Step 2: Mix the Filling
In a large mixing bowl, combine the cooled sausage mixture with 4 oz of room-temperature cream cheese, 2 cups of grated white cheddar, 1/2 teaspoon of paprika, and 3 sliced green onions. Use a spatula to thoroughly mix the ingredients until smooth and well combined, ensuring the cream cheese is fully integrated into the filling for even flavor distribution.
Step 3: Prep the Croissants
Take 6 stale croissants and slice them in half lengthwise, creating a top and bottom for each. Arrange the bottom halves in a greased 9×13 inch baking dish, gently pressing them down. Next, evenly distribute the sausage and cheese mixture over the croissant bottoms, then layer the top halves back on top, pressing down slightly to nestle them into the filling.
Step 4: Mix the Custard
In a separate bowl, whisk together 10 large eggs, 1 1/4 cups of half-and-half, 1 tablespoon of Dijon mustard, 2 tablespoons of hot sauce, and a pinch of kosher salt and freshly cracked pepper. Blend everything until smooth, which will form the custard base that brings the croissant breakfast casserole to life.
Step 5: Pour and Set
Carefully pour the custard mixture over the layered croissants, ensuring it seeps into the nooks and crannies. Reserve about a cup of the custard for topping later. Cover the dish with plastic wrap or foil and let it rest in the refrigerator for at least 1 hour, or overnight if preparing ahead, allowing the croissants to soak up the custard goodness.
Step 6: Bake the Casserole
Preheat your oven to 375°F (190°C). Remove the cover from the casserole and brush the tops with the reserved custard. Sprinkle with 2 tablespoons of Everything Bagel seasoning and some additional grated cheese for an extra touch. Cover the dish with foil to prevent over-browning, and bake for 30 minutes. Then, remove the foil and continue baking for another 15-20 minutes or until the top is golden and set in the center.
Step 7: Cool and Serve
Once finished baking, take the Croissant Breakfast Casserole out of the oven and let it cool for about 10 minutes. This resting period helps firm up the custard. Slice into squares and serve warm, allowing everyone to enjoy this comforting brunch delight with a smile.
Make Ahead Options
These Croissant Breakfast Casserole preparations are perfect for busy mornings! You can assemble the entire casserole up to 24 hours in advance and refrigerate it, allowing the buttery croissants to soak up the delicious custard overnight for deeper flavor. Just follow the steps to layer the croissants and filling, then pour the custard over. Cover with plastic wrap or foil to maintain freshness and prevent drying out. When ready to bake, simply preheat the oven and remove the cover, brushing the tops with any reserved custard. Bake as directed, and you’ll have a mouthwatering breakfast ready with minimal effort, making your morning routine a breeze!

Expert Tips for Croissant Breakfast Casserole
-
Use Stale Croissants: This helps absorb the custard better. If using fresh croissants, let them dry for a few hours to achieve optimal texture.
-
Don’t Rush the Cooling: Allow the sausage and vegetable mixture to cool slightly before combining with the cream cheese. This prevents the cheese from melting prematurely and ensures a well-blended filling.
-
Rest Time Matters: Let the casserole sit for at least an hour, or overnight in the fridge, to enhance flavor melding and improve the custard’s absorption.
-
Keep an Eye on Baking: Ovens vary, so monitor your casserole closely toward the end of the baking time to achieve a perfectly golden top without overcooking.
-
Customize Your Spice Level: Adjust the amount of hot sauce in the custard to suit your family’s taste preferences. More spice can enhance the flavor complexity of your Croissant Breakfast Casserole!
-
Add Extra Crunch: For an even more delightful topping, sprinkle some extra cheese or breadcrumbs on top before baking for added texture!
Croissant Breakfast Casserole Recipe FAQs
What type of croissants are best for this recipe?
Using stale croissants will yield the best results as they soak up the custard beautifully, giving you that rich flavor. If you only have fresh croissants, slice them and let them dry out for a few hours before using them in the casserole.
How should I store leftovers from the Croissant Breakfast Casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. This makes it easy to enjoy quick breakfasts during the week. Just reheat in the microwave or oven at 350°F (175°C) until warmed through.
Can I freeze the Croissant Breakfast Casserole?
Absolutely! You can freeze the casserole for up to 2 months. Once it has cooled completely, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. When you’re ready to enjoy, thaw it overnight in the refrigerator and reheat in the oven until hot and bubbly.
What if I don’t have breakfast sausage?
If you prefer a different protein or have dietary restrictions, ground turkey, chicken, or even plant-based sausage can be excellent substitutes. Just ensure they’re cooked through and seasoned to your liking for the best depth of flavor.
Are there any dietary considerations for this recipe?
This recipe contains dairy and eggs, so it’s not suitable for those with lactose intolerance or egg allergies. To adapt it for a dairy-free option, you could try using non-dairy cream cheese and almond milk in place of half-and-half. Just be mindful that this may slightly alter the texture and flavor.
How do I avoid a soggy casserole?
To prevent sogginess, ensure that you use stale croissants, and allow the casserole to rest for at least 1 hour (or overnight in the fridge) after pouring on the custard. This resting time helps the croissants absorb the custard and enhances the overall texture!
