Ingredients
1 (14 oz) smoked sausage (kielbasa or andouille), sliced into rounds
2 lbs russet or Yukon gold potatoes, peeled and diced
1 (10.5 oz) can cream of chicken soup
1 cup sour cream
1/2 cup whole milk

How To Make Smoked Sausage & Cheesy Potato Casserole
Preheat oven to 375°F (190°C). Grease a 9×13-inch baking dish with nonstick spray or butter.
Prepare the sauce: In a large bowl, whisk together the cream of chicken soup, sour cream, milk, 1½ cups of shredded cheese, garlic powder, onion powder, salt, and pepper until smooth.
Assemble: Add diced potatoes and sliced sausage to the baking dish. Pour the cheese sauce over the top and gently mix until evenly combined.
Bake: Cover the dish with foil and bake for 45 minutes. Remove foil, sprinkle remaining ½ cup cheese on top, and bake uncovered for another 15–20 minutes, or until potatoes are fork-tender and the top is golden and bubbly.
Cool and serve: Let the casserole rest for 5–10 minutes before serving. Garnish with chopped green onions or parsley, if desired
