A turkey sausage and egg white casserole is a baked breakfast dish made with cooked turkey sausage, egg whites, and a variety of vegetables and seasonings. It’s high in protein, low in calories, and ideal for those following a clean eating or low-carb diet. The casserole bakes until golden and firm, making it easy to slice into healthy, grab-and-go portions.
pound turkey sausage (ground or links, cooked and crumbled)
12 large egg whites (or 3 cups liquid egg whites)
½ cup low-fat milk (or almond milk for dairy-free option)
1 cup shredded mozzarella or reduced-fat cheddar cheese
1 cup baby spinach, chopped
1 small red bell pepper, diced
1 small onion, finely chopped
½ teaspoon garlic powder
½ teaspoon black pepper
½ teaspoon salt (optional, adjust to taste)
½ teaspoon Italian seasoning (optional)
1 tablespoon olive oil (for sautéing)
Non-stick spray or butter (for greasing)
Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish with non-stick spray or butter.
In a skillet, heat olive oil over medium heat. Add turkey sausage and cook until browned and fully cooked. Drain excess fat and set aside.
In the same skillet, add onion and bell pepper. Cook for 3–4 minutes until softened, then stir in chopped spinach until wilted. Remove from heat.
In a large bowl, whisk together egg whites, milk, garlic powder, salt, black pepper, and Italian seasoning until smooth and well combined.
Spread cooked sausage evenly across the baking dish. Add the sautéed vegetables on top. Pour the egg white mixture evenly over the sausage and vegetables. Sprinkle shredded cheese on top.
Bake uncovered for 35–40 minutes, or until the eggs are set and the top is lightly golden.
Let the casserole cool for 5–10 minutes before slicing. Serve warm and enjoy your healthy, delicious breakfast.
