Creating the Pioneer Woman Breakfast Casserole is easy with these clear steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Cook Sausage: In a large skillet, cook the breakfast sausage over medium heat until it’s browned and cooked through. Drain excess fat if necessary.
3. Whisk Eggs: In a large mixing bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until well combined.
4. Combine Ingredients: Stir in the cooked sausage, shredded cheese, diced bell peppers, and diced potatoes. Mix until evenly distributed.
5. Grease Baking Dish: Lightly grease a 9×13-inch baking dish with cooking spray or butter.
6. Pour Mixture: Pour the egg mixture into the prepared baking dish, spreading it out evenly.
7. Bake: Place the casserole in the preheated oven and bake for 35-40 minutes, or until the eggs are set and the top is lightly golden.
8. Cool Slightly: Remove the casserole from the oven and allow it to cool for about 5-10 minutes before serving.
9. Garnish: If desired, garnish with chopped green onions for added flavor and color.
