3 cups Russet potatoes, parboiled and cut into cubes
1 pound smoked and cured sausage, thinly sliced
4 tablespoons butter
4 tablespoons flour
2 cups milk
Salt, to taste
Ground black pepper, to taste
1 8-ounce package cream cheese
1 cup mozzarella cheese, shredded
1 teaspoon paprika
Preheat the oven to 350 degrees F. Place the potatoes and sliced sausages into a large bowl.
In a medium saucepan, melt butter over medium heat. When melted, add flour and whisk to fully incorporate. Let cook for 2 minutes before gradually adding milk, whisking the entire time.
Season with salt and black pepper and add cream cheese, breaking it up as you do. Whisk until cream cheese melts.
Pour the entire mixture into a 9-by-13 casserole dish. Use a rubber spatula to smooth the surface, and sprinkle mozzarella cheese evenly over the top. Sprinkle with paprika.
Place casserole into the preheated oven and cook for about 45 minutes, until the top is golden brown and the potatoes are fully cooked.
