Preheat oven to 375°F and grease a 9x13 baking dish.
In a skillet over medium heat, cook the sausage until browned and fully cooked. Drain excess grease and let cool slightly.
In a blender, blend together eggs, milk, cottage cheese, salt, pepper, and garlic powder until smooth.
Stir in cooked sausage and shredded cheese.
Pour mixture into prepared baking dish and spread evenly.
Bake for 30-35 minutes, or until the center is set and no longer jiggly.
Let rest 5–10 minutes before slicing and serving.
