• 1 cup shredded cheddar cheese

How to Make Overnight Croissant Breakfast Casserole Bake with Gravy

Step 1: Prepare the Sausage Mixture

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until softened and translucent. Crumble in the breakfast sausage and cook until fully browned. Drain any excess fat from the pan but reserve it for later use in the gravy.

Step 2: Assemble the Casserole

In a large bowl, combine the cooked sausage mixture, torn croissants, and shredded cheddar cheese. Transfer this mixture into a greased 9×13-inch baking dish.

Step 3: Mix Wet Ingredients

In another bowl, whisk together the eggs, heavy whipping cream, ½ cup of milk, dry mustard powder, salt, black pepper, paprika, and garlic powder until well combined. Pour this mixture over the croissant layer in your baking dish.

Step 4: Refrigerate Overnight

Cover your baking dish tightly with plastic wrap and place it in the refrigerator overnight or for at least 8 hours to allow flavors to meld.

Step 5: Preheat Oven & Bake

The next morning, remove your casserole from the fridge and preheat your oven to 350°F (175°C). Bake uncovered for about 35-45 minutes until golden brown on top.

Step 6: Make the Gravy

While your casserole is baking, melt butter along with reserved sausage fat in a saucepan over medium heat. Add flour and whisk until smooth. Cook this mixture for about a minute before gradually adding in remaining milk while whisking continuously. Let it simmer on low heat until thickened; season with additional salt and pepper as needed.

Step 7: Serve & Enjoy!

Slice your casserole into portions and serve hot with gravy poured over each slice or on the side. Enjoy this hearty meal that’s sure to impress!

• Skipping the Refrigeration: Not letting the casserole sit overnight can lead to a soggy texture. Always refrigerate for at least 8 hours for the best results.

• Overcooking the Sausage: Cooking the sausage too long can dry it out. Brown it until fully cooked but remove it from heat as soon as it’s done to keep it juicy.
• Neglecting Seasoning: Under-seasoning can result in bland flavors. Taste and adjust salt and pepper in both the casserole and gravy to enhance taste.
• Not Whisking Eggs Well: Poorly whisked eggs can lead to uneven cooking. Whisk until fully combined to ensure even distribution of flavors.
