Step-by-Step Instructions for the Perfect Breakfast Casserole

Follow these simple steps to create the perfect high protein breakfast casserole:

1. Preheat and Prep: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking and allow easy serving.
2. Sauté Beef Sausage and Vegetables: In a skillet over medium heat, cook your choice of beef sausage until browned and fully cooked. Add chopped vegetables and sauté for 3-5 minutes until slightly softened. Set aside to cool slightly.
3. Whisk Egg Mixture: In a large bowl, whisk together eggs, cottage cheese, milk, and seasonings including garlic powder, onion powder, paprika, salt, and black pepper. The cottage cheese adds creaminess while boosting protein content.
4. Combine Ingredients: Fold the cooked beef sausage and vegetables into the egg mixture. Add oats and shredded cheese, gently stirring to distribute evenly. Ensure all ingredients are well combined to create a uniform casserole.
5. Pour into Baking Dish: Pour the mixture into the prepared baking dish, spreading it evenly. Top with extra cheese if desired for a golden, melty crust.
6. Bake to Perfection: Bake for 45-50 minutes or until the eggs are fully set and the top is golden brown. A knife inserted in the center should come out clean. Allow to cool for 5-10 minutes before slicing to maintain shape and texture.
7. Serve and Enjoy: Cut into squares and serve warm. This casserole pairs well with fresh fruit, a green salad, or avocado slices for a complete meal.
