Ingredients
- 1 lb smoked sausage, sliced into rounds

- 2 tbsp butter
- 2 tbsp all-purpose flour
- 1 ½ cups low-fat milk
- 1 cup shredded cheddar cheese

- ½ tsp garlic powder
- ½ tsp paprika
- Salt and pepper, to taste
- Cooking spray or light butter, for greasing
- Optional garnish: chopped parsley or green onions
Instructions
1. Preheat Oven & Prepare Dish
Preheat oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter.
2. Cook the Sausage
In a large skillet over medium heat, cook the sliced sausage until browned. Remove from pan and set aside.
3. Sauté Onions & Make the Sauce
In the same pan, melt the butter. Add diced onions and cook until softened. Stir in the flour and cook for 1 minute to form a roux. Gradually whisk in the milk until smooth and slightly thickened.
4. Add Seasonings & Cheese
Stir in garlic powder, paprika, salt, and pepper. Add cheddar and mozzarella cheese, stirring until melted into a creamy sauce.
5. Assemble the Casserole
In the prepared baking dish, layer the diced potatoes and cooked sausage. Pour the cheese sauce evenly over the top, stirring gently to coat.
6. Bake
Cover with foil and bake for 30 minutes. Remove foil and bake an additional 15–20 minutes, until the top is golden and bubbly and the potatoes are tender.
7. Serve
Let the casserole cool for 5 minutes, garnish with parsley or green onions, and serve warm.
