Ingredient Notes and Substitutions
Sausage options:
Traditional breakfast sausage gives the richest flavor, but you can easily substitute cooked turkey sausage or chicken sausage for a lighter option. For a vegetarian version, use plant-based sausage crumbles or sautéed mushrooms.
Dairy swaps:
If you don’t have sour cream, plain Greek yogurt works very well and adds extra protein. Whole milk creates the creamiest texture, but low-fat milk can also be used.
Cheese choices:
Cheddar is classic, but Colby Jack, Monterey Jack, Swiss, or a mild Mexican blend all work nicely. For a little heat, try pepper jack.
Vegetables:
Bell peppers add color and mild sweetness, but you can also add spinach, zucchini, mushrooms, or onions. Just be sure to sauté watery vegetables first so the casserole doesn’t become soggy.
Seasoning:
This recipe is gently seasoned so it appeals to kids and adults alike. If your family likes more flavor, add garlic powder, paprika, or a pinch of red pepper flakes.
Step-by-Step Instructions
This easy sausage and egg casserole comes together quickly with just a few simple steps.
Step 1 – Preheat and Prepare the Pan
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or nonstick spray to prevent sticking.
Step 2 – Brown the Sausage
In a large skillet over medium heat, cook the sausage until fully browned, breaking it into small crumbles as it cooks. Once done, drain any excess grease and set the sausage aside.
Step 3 – Sauté the Vegetables
Using the same skillet, add the diced bell peppers and sliced green onions. Sauté for a few minutes until slightly softened and fragrant. This step enhances their flavor and prevents excess moisture in the casserole.
Step 4 – Mix the Egg Base
In a large bowl, whisk together the eggs, sour cream, milk, salt, and black pepper until smooth. Stir in the shredded cheese, cooked sausage, and sautéed vegetables.
Step 5 – Assemble the Casserole
Pour the mixture evenly into the prepared baking dish. Use a spatula to gently spread everything out so the ingredients are evenly distributed.
Step 6 – Bake Until Set
Bake uncovered for 35 to 50 minutes, or until the edges are set and the center is just barely jiggly. The casserole will continue to firm up as it rests.
Step 7 – Rest and Serve
Let the casserole rest for 5–10 minutes before slicing. This makes it easier to serve clean portions.
Pro Tips for Success
- Don’t overbake. The center should be just set; overbaking can make the eggs dry.
- Drain sausage well. Too much grease can make the casserole heavy.
- Let it rest. Resting helps the casserole firm up and improves texture.
- Use room-temperature eggs. They blend more smoothly into the mixture.
- Customize thoughtfully. Pre-cook any vegetables that release moisture.
Flavor Variations
This easy sausage and egg casserole is a great base for experimenting with flavors.
- Southwest Style: Add diced green chiles, pepper jack cheese, and a pinch of cumin.
- Veggie Lover’s: Skip the sausage and load up on mushrooms, spinach, and zucchini.
- Italian-Inspired: Use Italian chicken sausage and add mozzarella with a sprinkle of oregano.
- Spicy Kick: Add chopped jalapeños or a dash of hot sauce to the egg mixture.
- Extra Cheesy: Mix two types of cheese for added depth and richness.
Serving Suggestions
This casserole is hearty on its own, but pairing it with lighter sides creates a balanced breakfast.
- Fresh fruit salad or sliced melon
- Toast, biscuits, or croissants
- Hash browns or roasted breakfast potatoes
- Yogurt parfaits for a lighter option
It also works beautifully as part of a brunch spread with pancakes, muffins, or cinnamon rolls.
Storage and Freezing Instructions
Refrigerator:
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. Reheat individual portions in the microwave or warm larger portions in the oven.
Freezer:
This casserole freezes well. Let it cool completely, then wrap tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
Make-Ahead Tip:
Assemble the casserole the night before, cover tightly, and refrigerate. In the morning, let it sit at room temperature for about 15 minutes before baking.
