How to Make Smoked Sausage & Cheesy Potato Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C).
Grease a 9×13-inch baking dish with nonstick spray or butter.
Step 2: Make the Cheese Sauce
In a large bowl, whisk together:
-
Cream of chicken soup
-
Sour cream
-
Milk
-
1½ cups of the shredded cheddar cheese
-
Garlic powder
-
Onion powder
-
Salt and black pepper
Mix until smooth and fully combined.
Step 3: Assemble the Casserole
Add the diced potatoes and sliced smoked sausage to the prepared baking dish.
Pour the cheese sauce evenly over the top and gently stir until everything is well coated.
Step 4: Bake
Cover the dish tightly with foil and bake for 45 minutes.
Remove the foil, sprinkle the remaining ½ cup cheddar cheese over the top, and return to the oven uncovered.
Bake for an additional 15–20 minutes, or until the potatoes are fork-tender and the top is golden and bubbly.
Step 5: Rest and Serve
Remove from the oven and let the casserole rest for 5–10 minutes before serving.
Garnish with chopped green onions or parsley if desired.
