Step 1: Preheat oven - Set the oven to 350°F (175°C) and grease a 9×13-inch baking dish with butter or non-stick spray.
Step 2: Cook the sausage - In a skillet over medium heat, cook the sausage until browned and no longer pink. Drain any excess fat and let it cool slightly.
Step 3: Mix the egg base - In a large mixing bowl, whisk together eggs, milk, cottage cheese, garlic powder, onion powder, salt, and pepper until smooth and well combined.
Step 4: Assemble the casserole - Spread the cooked sausage evenly in the prepared baking dish. Pour the egg mixture over the sausage and sprinkle shredded cheddar cheese on top.
Step 5: Bake the casserole - Bake uncovered for 35–40 minutes, or until the center is set and the top is lightly golden.
Step 6: Rest and serve - Allow the casserole to cool for 5–10 minutes before slicing. Serve warm and enjoy a creamy, cheesy, and satisfying breakfast.
