Ingredients
- 1 pound ground breakfast sausage such as Jimmy Dean
- 12 large eggs
- 1 cup sour cream
- ¾ cup milk
- 2 cups shredded cheddar cheese divided
- 28 oz. thawed shredded hash browns patted dry
- ½ small yellow onion finely diced
- ½ red bell pepper diced
- ½ green bell pepper diced
- 4 tablespoons melted butter
- 1 teaspoon hot sauce
- Seasonings:
- ½ teaspoon mustard powder
- ¼ teaspoon dried oregano
- ¼ teaspoon dried thyme
- ¼ teaspoon ground sage
- ½ teaspoon salt
- ¼ teaspoon black pepper
Instructions
- Preparation
- Preheat the oven to 350°F and position the rack in the center of the oven.
- In a skillet over medium-high heat, cook and crumble the sausage until browned and fully cooked. Add the diced onions and peppers during the last few minutes of cooking. Once browned, drain any excess grease and set the mixture aside.
- In a medium bowl, whisk together the eggs until just combined. Add the sour cream, milk, hot sauce, mustard powder, oregano, thyme, sage, salt, and pepper. Stir until the mixture is well-blended.
- Assembling and Baking
- Lightly grease a 9x13-inch casserole dish and spread the thawed hash browns evenly across the bottom. Drizzle with melted butter, then toss to ensure an even coating.
- Sprinkle one cup of shredded cheddar cheese over the hash browns, followed by the cooked sausage, onions, and peppers.
- Pour the egg mixture over the layered ingredients, then top with the remaining cheddar cheese.
- Bake the casserole, uncovered, for approximately 50 minutes. Check the casserole every 5 minutes after this point; it’s done when the edges are slightly browned and the center is nearly set. It will continue to firm up while resting.
- Allow the casserole to rest for 10 minutes before slicing and serving.
