Ingredient Notes
- ground breakfast sausage: You can use chicken or pork sausage depending on your preference.
- bag of frozen bell peppers and onions
- avocado oil or olive oil
- can green chiles
- frozen hash browns: I used shredded hashbrowns. You can substitute tater tots if desired.
- shredded cheddar cheese: Use mild or sharp cheddar cheese as desired.
- shredded mozzarella cheese: For a kick, use pepper jack cheese.
- large eggs
- egg whites
- salt and black pepper
- taco seasoning
- hot sauce
- garlic powder
- milk of choice: You can use whole milk, low-fat milk, or plant-based milk of choice.
- cottage cheese: You can substitute Greek yogurt, dairy-free yogurt, or even sour cream if desired.
- green onion or fresh chives for garnish
Step-by-Step Instructions
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
- Heat the olive or avocado oil in a large skillet over medium heat. Add the sausage, breaking it apart into small pieces with a spoon or spatula, and cook until browned. Remove any excess grease.
- In a large bowl, whisk together the eggs, cottage cheese, milk hot sauce, and seasoning. Mix until well combined.
- Add the frozen hash brown potatoes, frozen peppers/onions, green chilis, 1/2 cup shredded cheddar cheese, ½ cup shredded mozzarella cheese, and the cooked sausage mixture to the casserole dish. Mix everything together until evenly combined and spread out evenly in the pan.
- Pour the egg mixture over the hashbrowns, veggies, and sausage, and cover with the remaining cheese.
- Bake in the preheated oven for 45-55 minutes, or until the casserole is set in the middle and the top is golden brown. If getting too brown, feel free to cover it with aluminum foil.
- Once done, remove the casserole from the oven and let it cool for a few minutes before slicing.
- Garnish with Greek yogurt, and sprinkle with chopped fresh chives or green onions.
Mac’s Pro Tip
Expert Tips & Variations
- To make this hash brown breakfast casserole dairy-free, use dairy-free yogurt and vegan cheese shreds (or omit the cheese).
- Feel free to add cooked and chopped ham or bacon for additional meat in this recipe, or substitute it entirely.
Storage Tips
Store leftovers in an airtight container in the fridge for up to 3-4 days. Reheat gently in the microwave and serve with desired toppings.
To freeze, I recommend letting the casserole cool completely. Then, wrap individual servings in plastic wrap and store them in an airtight, freezer-safe container or freezer bag for up to 2-3 months.
