The Process for Making Easy Sausage and Veggie Egg Casserole

Making the Easy Sausage and Veggie Egg Casserole is as satisfying as eating it! Follow these simple steps to create a delicious breakfast that your whole family will love. Let’s dive into the process!
Start by preheating your oven to 350 degrees F. This ensures that your casserole cooks evenly and gets perfectly golden brown on top.
In a large skillet over medium-high heat, add the ground turkey or chicken sausage. Cook it until it’s all crumbled and browned—this should take about 7 to 10 minutes. Once done, transfer the cooked sausage to a plate. You want to leave some of that flavorful grease in the skillet for the vegetables.
Now, drizzle the skillet with olive oil. This will help sauté your onion and bell peppers. Add the chopped onion and both the diced red and green bell peppers to the skillet. Sauté them until the onions become translucent, which usually takes about 6 minutes. The colors will brighten and the aroma will be incredible!
Next, toss in the baby spinach and cook until it’s just starting to wilt. This adds a vibrant green touch to your casserole and boosts the nutrition factor.
Grease a 9×13 casserole dish with nonstick spray. In this dish, combine your cooked sausage with the sautéed vegetable mixture. Sprinkle the chopped green onions on top for an extra layer of flavor.
In a large bowl, whisk together the eggs, half and half, salt, pepper, and dried mustard. This mixture is what will bind your casserole together and give it that fluffy texture.
Next, stir in the shredded cheese. This adds a rich, creamy element to your dish that everyone will love. Pour this egg mixture over the sausage and veggie combination in the casserole dish, making sure everything is evenly combined.
Now it’s time to bake! Place your casserole in the preheated oven and bake for 35 to 40 minutes. You’ll know it’s done when the top is set and the edges are slightly browned. The smell wafting through your kitchen will be mouthwatering!
Once removed from the oven, let it cool for a few minutes before slicing. Serve warm and enjoy the delicious flavors of your Easy Sausage and Veggie Egg Casserole!
