Step-by-Step Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
  2. Heat the olive or avocado oil in a large skillet over medium heat. Add the sausage, breaking it apart with a spoon or spatula, and cook until browned. Remove any excess grease. Add the bell peppers and onions to the skillet. Sauté until the peppers and onions are softened and slightly caramelized, stirring occasionally.
  3. In a large mixing bowl, whisk together the eggs, Greek yogurt, milk, and seasoning. Mix until well combined.
  4. Add the frozen hash brown potatoes, 1/2 cup shredded cheddar cheese, ½ cup shredded mozzarella cheeses, and the cooked sausage, peppers, and onions to the bottom of the casserole dish. Mix everything together until evenly combined and spread out in a single layer in the pan.
  5. Pour the egg mixture over the hashbrowns, veggies, and sausage, and sprinkle the top of the casserole with the remaining cheese.
  6. Bake in the preheated oven for 45-55 minutes, or until the casserole is set in the middle and the top is golden brown.
  7. Once done, remove the casserole from the oven and let it cool for a few minutes before slicing.
  8. Garnish with chopped fresh parsley, fresh chives, or green onions.

Recipe FAQs

Why is my tater tot casserole soggy? 

Make sure you use a large enough casserole dish as overcrowding the tater tots might cause sogginess. Be sure to drain the breakfast sausage before adding to the casserole as well.
