Ingredients
See recipe card at the bottom of the post for the full list of ingredients and exact quantities.
Pork sausage. I use regular pork sausage, but you can also use turkey sausage or seasoned sausages like breakfast sausage, hot sausage, or Italian sausage.
Cheddar cheese. I use sharp cheddar cheese because I love the bold 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 yellow, orange, or green bell pepper.
Dijon. A little bit of Dijon adds rich flavor to the egg bake.
How to Make Sausage Egg Bake
Step 1: Brown sausage with salt and pepper in a large skillet over medium-high heat, breaking it up into small pieces, until the meat is no longer pink. Drain off excess grease.
Step 2: Whisk eggs in a large bowl. Add milk, sour cream, Dijon, salt, and black pepper, and whisk until combined.
Step 3: Place cooked sausage in a greased 3-quart casserole dish. Add the diced red pepper, sliced green onions, and 1 cup of shredded cheese. Evenly pour egg mixture on top.
If making ahead, cover with aluminum foil or plastic wrap and chill for up to 24 hours. Let it sit at room temperature for 30 minutes before baking.
Step 4: Bake in preheated oven at 350 degrees for 40-45 minutes or until the center is just about set. Add remaining 1 cup of cheese and bake for 5 more minutes or until the cheese is melted.
Cool for 10 minutes.
Serve with hot sauce or salsa, Fluffy Pumpkin Pancakes, Apple Cinnamon Roll Bake, hash browns, and a fresh fruit salad.
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.
- If you're baking this the next day, let it sit at room temperature for about 30 minutes before baking. If it's still cold, you may need to add a few minutes to the bake time.
