Ingredients
Please refer to the recipe card for the full list of ingredients and exact quantities.
Eggs. You'll need a full dozen eggs.
Pork sausage. You can use regular pork sausage or breakfast sausage, which is usually seasoned with spices. If you like it spicy, use hot sausage.
Cheddar cheese. Two cups of cheese -- half goes into the filling and half gets melted on top. I use sharp cheddar cheese because I love the flavor. You can use mild cheddar or a different kind of cheese like Monterey Jack, pepper Jack, mozzarella cheese, Swiss, or a combination.
Sour cream. Sour cream whipped in with the eggs and milk makes the eggs super creamy.
Green onions. Green onions add fresh, mild onion flavor and pretty green color. You can also use red onion or shallots.
Red bell pepper. I love red peppers because they are the mildest of the bell peppers, but you can use green, yellow, or orange.
Dijon. A little bit of Dijon adds rich flavor to the egg bake.
Step-by-Step Instructions
1. Prep the pan and oven, if baking immediately.
Spray a 3-4 quart casserole dish with nonstick cooking spray. If baking immediately, preheat the oven to 350.
2. Brown the sausage.
Place the sausage in a large skillet, season it with salt and pepper and brown over medium-high heat until it is no longer pink. Drain off excess grease.
3. Make the egg mixture.
Whisk the eggs in a large bowl. Add the milk, sour cream, Dijon, salt, and black pepper, and whisk until combined.
4. Assemble the sausage egg bake.
Place the cooked sausage in the casserole dish. Add the diced red pepper, sliced green onions, and 1 cup of cheese.
Evenly pour egg mixture on top.
5. If making ahead, cover and refrigerate.
Cover the baking dish with aluminum foil or plastic wrap and chill for up to 24 hours before baking. The next day, let it sit at room temperature for 30 minutes before baking.
6. Bake.
Bake for 40-45 minutes or until the center is just about set.
Add the remaining 1 cup of cheese in an even layer and bake for 5 more minutes or until the cheese is melted.
Let it cool for 10 minutes. Slice, serve, and enjoy!

FAQs
Eggs can get tough and rubbery when they're overcooked. When you make this egg sausage casserole recipe, bake it until the center is just set. You can tell if it's done when a knife inserted in the center comes out clean.
No, there is no need to cover this easy egg casserole when you bake it.
The internal temperature should read at least 160 degrees. You can also insert a knife into the center --- if it comes out clean, it's done.
Expert Tips
Whisk the eggs before adding the rest of the egg mixture ingredients. It can be difficult to tell if you've broken all the yolks once the sour cream and milk have been added.
Be careful not to overbake your sausage egg casserole or it can become tough. Bake until the center is just about set, then add the cheese.
