Step-by-Step Instructions

Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.
Cook 1 pound of breakfast sausage over medium heat until browned and no longer pink. Drain excess fat.
Tear 6–8 croissants into bite-sized pieces and layer them evenly in the baking dish.
Spread the cooked sausage evenly over the croissants.
In a mixing bowl, whisk together 8 large eggs, 2 cups of milk, 1 cup of shredded cheddar cheese, ½ teaspoon salt, ¼ teaspoon black pepper, and a pinch of garlic powder.
Pour the egg mixture evenly over the croissants and sausage, pressing down gently to help pieces soak up the custard.
Cover the dish with foil and bake for 30 minutes, then remove foil and bake uncovered for an additional 15 minutes until the top is golden and the custard is set.
Let the casserole rest 5 minutes before serving. Enjoy warm for a melt-in-your-mouth texture and rich flavors.

Key Tips to Perfect Your Sausage Croissant Casserole

Use day-old croissants for better absorption of the custard without becoming soggy.
Don’t skip draining the sausage fat to avoid a greasy casserole.
Customize by adding diced bell peppers, mushrooms, or fresh herbs for added freshness.

Prepare the casserole the night before and refrigerate overnight for an easy grab-and-bake meal.

Adding Flavor Variations and Sides

Spice it up with red pepper flakes or a dash of hot sauce mixed into the egg custard.
Top with sliced green onions or crispy bacon bits for texture.
