Step-by-Step Guide – How to Make Sausage Egg and Croissant Breakfast Casserole

Step 1: Prepare the Sausage

In a large skillet over medium heat, crumble and cook the sausage until browned and fully cooked. If using onions and bell peppers, add them to the skillet about halfway through cooking the sausage to soften. Once cooked, drain any excess grease and set aside.

Step 2: Tear the Croissants

While the sausage cools slightly, tear your croissants into bite-sized pieces and place them evenly in a greased 9×13-inch casserole dish. The croissants will soak up the egg mixture and become perfectly tender after baking.

Step 3: Mix the Eggs and Milk

In a large bowl, whisk together the eggs, milk (or half-and-half), salt, pepper, and dried herbs if using. Make sure the mixture is well combined and slightly frothy for the best texture.

Step 4: Assemble the Casserole

Sprinkle half of the shredded cheese over the croissant pieces in the casserole dish. Then evenly distribute the cooked sausage mixture on top. Pour the egg mixture over everything, pressing down gently to make sure the croissants soak up the liquid.

Finally, sprinkle the remaining shredded cheese on top.

Step 5: Bake

Preheat your oven to 350°F (175°C). Cover the casserole dish with foil and bake for 30 minutes. After 30 minutes, remove the foil and bake for an additional 15-20 minutes until the top is golden brown and the egg is fully set.

Step 6: Let It Rest and Serve

Once out of the oven, allow the casserole to rest for about 5-10 minutes. This helps the casserole set further and makes it easier to cut into squares. Serve warm with your favorite breakfast sides like fresh fruit, coffee, or juice.
