This sausage and egg casserole is one of over 15 different ways to cook eggs for breakfast. A family-favorite recipe that is healthy, easy to make, and perfect for a quick weekday meal, baby or bridal shower, or holiday gathering. The recipe serves 6 and may easily be doubled to serve more people.
Spray your casserole dish with nonstick cooking spray (I like avocado oil spray) or grease with oil or butter to prevent the egg casserole from sticking to the bottom of the pan.
In a large skillet, over medium-high heat, melt the butter. Once melted, add the sausage and break it up with a wooden spoon to create crumbles. After about 3 minutes, stir in the diced potatoes. Cover the skillet and cook until the sausage is brown and the potatoes begin to sweat and soften (about 8-10 minutes).
Add the spinach to the skillet and continue to cook, uncovered, for about 2 minutes until wilted. Stir in the chopped green onions.
Pour the veggie and sausage mixture into the casserole dish and spread it out in an even layer. Instead of a casserole dish, you can use the same skillet used to cook the sausage and potatoes, as long as it's oven-safe. If you're doing this, simply turn off the heat and move to the next step.
In a medium-size bowl, whisk the eggs, milk, cheddar cheese, fresh herb, salt, and pepper.
Pour the egg mixture over the top of the cooked sausage mixture.
Bake the casserole for 30-40 minutes, or until the center of the casserole is firm. Check on the casserole around the 30 minute mark.
How many eggs should you use? For a medium baking dish (such as a 2-quart casserole dish), use 6 eggs. If you're using a large casserole dish, use extra eggs, up to 10 eggs. I'm leaving this up to you. Either way, you'll end up with a great breakfast. One option is to use 6 eggs at first, then pour the egg mixture over the sausage crumbles. If you feel you need more eggs, whisk 2-4 additional eggs in a bowl and pour over the casserole before baking.If you're feeding a crowd, double this recipe (12 eggs, 2 pounds of sausage, etc.) and bake the egg casserole in a 13x9 casserole dish. The casserole may need to bake for as long as 50 minutes.
