Instructions

Step 1: Preheat oven to 350°F (175°C). In a large skillet over medium heat, cook 12 oz turkey sausage, breaking into small crumbles, for 8-10 minutes until browned and cooked through. Drain excess fat and set aside.
Step 2: In a large bowl, whisk together 8 large eggs, 1 1/2 cups milk, 1/2 teaspoon garlic powder, 1/4 teaspoon onion powder, 1/4 teaspoon salt, and 1/4 teaspoon black pepper until smooth.
Step 3: Stir in 2 cups chopped fresh spinach and 12 oz cooked turkey sausage crumbles until well combined.
Step 4: Pour the mixture into a greased 9x13-inch baking dish and spread evenly. Sprinkle 1/2 cup shredded mozzarella cheese and 1/4 cup shredded Parmesan cheese evenly over the top.
Step 5: Cover with aluminum foil and bake for 30 minutes. Remove foil and bake for an additional 15-20 minutes, until the center is set and a knife inserted comes out clean.
