How to Make The Best Breakfast Casserole with Sausage
This Best Breakfast Casserole with Sausage is incredibly easy to assemble, making it a perfect make-ahead meal.

With a preparation time of just 20 minutes and 20 minutes of baking, you’ll be enjoying this delightful dish in no time, perfect for any morning.
Step-by-Step Instructions
- Brown the Sausage and Sauté Vegetables: In a large skillet, crumble and cook the breakfast sausage over medium heat until browned. Drain off any excess grease. Add the chopped onion and green bell pepper to the skillet with the sausage. Cook for 5-7 minutes, stirring occasionally, until the vegetables are softened. Remove the skillet from the heat.
- Prepare the Bread Cubes: While the sausage cooks, place the cubed French bread in a single layer on a baking sheet. If you prefer slightly crisper bread, you can toast it in the oven at 350°F (175°C) for about 5-10 minutes, or until lightly golden. This step is optional but adds a pleasant texture.
- Assemble the Casserole: In a large mixing bowl, combine the toasted or untoasted bread cubes, the cooked sausage and vegetable mixture, and the shredded cheddar cheese. Toss gently to distribute the ingredients evenly.
- Prepare the Egg Mixture: In a separate bowl, whisk together the eggs, milk, Dijon mustard, salt, black pepper, and optional red pepper flakes. Whisk until well combined and slightly frothy.
- Combine and Soak: Pour the egg mixture evenly over the bread, sausage, and cheese mixture in the large bowl. Gently press down with a spoon or spatula to ensure all the bread cubes are moistened by the egg mixture. Let the mixture sit for at least 15-20 minutes (or up to overnight in the refrigerator) to allow the bread to absorb the liquid. This soaking time is crucial for a tender, cohesive casserole.
- Bake the Casserole: Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish with butter or cooking spray. Pour the soaked casserole mixture into the prepared baking dish, spreading it evenly. Cover the baking dish tightly with aluminum foil.
- First Bake (Covered): Bake for 30 minutes with the foil on. This ensures the inside cooks through without the top browning too quickly.
- Second Bake (Uncovered): Remove the aluminum foil and continue baking for another 20-25 minutes, or until the casserole is puffed up, golden brown on top, and a knife inserted into the center comes out clean.
- Rest and Serve: Let the Best Breakfast Casserole with Sausage rest for 5-10 minutes before serving. This allows it to set properly and makes it easier to slice.
