Steps to Make It
- Preheat your oven to 350 ยฐF. This ensures the casserole cooks evenly and gets that lovely golden top.
- In a large skillet over medium heat, cook the turkey sausage until browned and fully cooked, about 8-10 minutes. The sausage should be nicely browned and fragrant, which means it’s ready for the next step.
- Add the diced onion and red bell pepper to the skillet. Sautรฉ for about 5 minutes until the vegetables are soft and the onion is translucent. This adds a nice sweetness and depth to the dish.
- Stir in the chopped spinach and cook for another 2-3 minutes until wilted. The vibrant green color will brighten up your mixture and add nutrients.
- In a large bowl, whisk together the eggs, milk, garlic powder, salt, and black pepper. This mixture should be smooth and well combined, ready to bring everything together.
- Add the cooked sausage and vegetable mixture to the egg mixture, stirring in the shredded cheddar cheese and sour cream. Everything should be mixed well, creating a creamy and flavorful filling.
- Pour the entire mixture into a greased 9×13 inch baking dish. Spread it evenly so it cooks uniformly.
- Bake in the preheated oven for 35-45 minutes, or until the casserole is set in the center and lightly golden on top. You can check doneness by inserting a knife; it should come out clean.
- Let it cool for a few minutes before slicing. This helps it hold together better when you serve it.
- Serve warm and enjoy! This casserole pairs wonderfully with fresh fruit or a side of toast.
Make It Perfect
- For extra flavor, add some herbs like parsley or chives before serving.
- If you want a spicier kick, consider adding diced jalapeรฑos to the sausage mixture.
- This casserole is great for meal prep; just store it in the fridge for up to 4 days.
Mix It Up
- Try adding diced zucchini or mushrooms for added veggies.
- Swap out the cheddar for feta or pepper jack cheese for a different flavor profile.
Perfect Partners
