How to Make Smoked Sausage & Cheesy Potato Casserole
Ingredients:
- 4 cups Frozen diced hash brown potatoes (Thawed)
- 2 cups Smoked sausage (Sliced into 1/2-inch rounds)
- 1.5 cups Shredded sharp cheddar cheese
- 1 cup Sour cream
- 1 can Cream of mushroom soup (10.5 oz)
- 0.5 cup Whole milk
- 0.5 cup Chopped yellow onion
- 2 tablespoons Unsalted butter (Melted)
- 1 teaspoon Garlic powder
- 1 teaspoon Salt
- 0.25 teaspoon Black pepper
- 0.5 teaspoon Paprika (Optional)
- 1 teaspoon Fresh parsley (Chopped, for garnish)
Directions:
- Preheat your oven to 375°F and lightly grease a 9×13-inch baking dish to prevent sticking.
- In a skillet over medium heat, lightly brown the sliced smoked sausage for about 5 minutes, turning occasionally for even color. Set aside once golden.
- In a large mixing bowl, combine the sour cream, cream of mushroom soup, whole milk, melted butter, garlic powder, salt, black pepper, and optional paprika. Stir until you have a smooth, creamy mixture.
- Add the thawed hash browns, browned sausage, chopped onion, and 1 cup of shredded cheddar cheese to the bowl. Mix everything together until well combined.
- Pour the casserole mixture into your prepared baking dish, spreading it out evenly. Sprinkle the remaining 1/2 cup of cheddar cheese across the top for a delicious cheesy crust.
- Bake uncovered in the preheated oven for 45 minutes, or until the top is golden and the casserole is bubbling around the edges.
- For an extra-crispy cheese topping, turn on the broiler for an additional 2–3 minutes—just keep a close watch to avoid burning.
- Remove from the oven and let the casserole rest for 5 minutes. Before serving, sprinkle with chopped parsley for a fresh burst of color and flavor.
