Make Easy Sausage and Veggie Egg Casserole: A Simple Method

Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C). This will ensure your casserole bakes evenly and comes out perfectly fluffy.
Step 2: Cook the Sausage
In a large skillet over medium heat, add 1 tablespoon of olive oil. Once hot, add the ground turkey or chicken sausage. Cook until browned and fully cooked, about 5-7 minutes. Use a spatula to break the sausage into smaller pieces as it cooks.
Step 3: Sauté the Veggies
Add the chopped onion, red bell pepper, and green bell pepper to the skillet with the sausage. Sauté until the veggies are tender, about 3-5 minutes. Stir in the roughly chopped spinach and cook until wilted. Remove from heat and let cool slightly.
Step 4: Whisk the Eggs
In a mixing bowl, crack all 12 eggs. Add the half and half (or milk), salt, pepper, and dried mustard. Whisk together until well combined and fluffy.
Step 5: Combine Ingredients
In the prepared baking dish, spread the sausage and veggie mixture evenly across the bottom. Pour the egg mixture over the top, ensuring everything is evenly distributed. Sprinkle the shredded cheddar cheese on top.
Step 6: Bake
Place the casserole in the preheated oven and bake for 30-35 minutes, or until the eggs are set and the top is golden brown. A toothpick inserted into the center should come out clean.
Step 7: Cool and Serve
Once baked, remove from the oven and let it cool for a few minutes. Garnish with chopped green onions before slicing into squares and serving. Enjoy warm!
Fresh Seasonal Changes

- Spring: Add asparagus or zucchini for a fresh twist.
- Summer: Toss in some diced tomatoes or corn for a burst of sweetness.
- Fall: Incorporate roasted sweet potatoes or butternut squash for a hearty flavor.
- Winter: Use kale instead of spinach for a more robust green.
What Could Go Wrong
While this Easy Sausage and Veggie Egg Casserole is quite forgiving, here are a few things to watch out for:
- Overcooking: Keep an eye on the casserole while it bakes to prevent the eggs from becoming rubbery.
- Undercooking: Ensure the eggs are fully set; runny eggs can be unappetizing.
- Ingredient Variations: If you change the type of sausage or cheese, be mindful of cooking times and flavors.
