Smoked Sausage and Cheesy Potato Casserole

This smoked sausage potato casserole mixes sliced sausage, hash browns, sour cream, and sharp cheddar into a bubbling dish that feeds a hungry family.

It is a stir and bake recipe that works for busy weeknights, potlucks, and brunch tables, and it asks for nothing more than a bowl, a skillet, and a baking dish.

Why This Smoked Sausage Potato Casserole Recipe Works

Browning the sausage first renders a little fat and adds a deeper savory edge to the whole casserole.

Cream of mushroom soup, sour cream, and milk blend into a sauce that keeps the hash browns moist while they bake.

A final sprinkle of cheddar on top turns golden and bubbly, and an optional broil adds a browned finish.

Ingredients for Smoked Sausage Potato Casserole

  • Base: 4 cups thawed frozen diced hash browns and 2 cups sliced smoked sausage
  • Sauce: 1 cup sour cream, 1 can cream of mushroom soup, 1/2 cup whole milk, and 2 tablespoons melted butter
  • Cheese and aromatics: 1 1/2 cups shredded sharp cheddar and 1/2 cup chopped onion
  • Seasoning: 1 teaspoon garlic powder, salt, pepper, optional paprika, and parsley to garnish

Hash browns. Thawing them first keeps extra water out of the sauce and helps the potatoes bake evenly.

Smoked sausage. It is fully cooked, so browning it adds color and a savory bite more than doneness.

Cheddar. Sharp cheddar stands up to the sausage and the creamy sauce without tasting flat.

Sour cream. It adds tang and body that balance the richness of the soup and cheese.

Cream of mushroom soup. The condensed soup acts as a shortcut sauce that seasons and binds everything together.

How to Make Smoked Sausage Potato Casserole

1. Heat the oven Heat the oven to 375 degrees F and lightly grease a 9 by 13 inch baking dish.

2. Brown the sausage Cook the sausage slices in a skillet over medium heat for about 5 minutes until lightly browned, then set them aside.

3. Mix the sauce Stir the sour cream, mushroom soup, milk, melted butter, garlic powder, salt, pepper, and paprika until smooth.

4. Add the solids Fold in the hash browns, sausage, onion, and 1 cup of the cheddar until evenly coated.

5. Fill the dish Spread the mixture into the baking dish and scatter the remaining 1/2 cup of cheddar over the top.

6. Bake Bake uncovered for 45 minutes until the edges bubble and the top turns golden.

7. Broil and rest For a browner top, broil for 2 to 3 minutes while watching closely, then rest the casserole for 5 minutes and add parsley.

How to Serve Smoked Sausage Potato Casserole

Serve big spoonfuls straight from the dish with a green side to cut the richness. Creamy buttermilk coleslaw adds crunch, soft and buttery homemade rolls soak up the sauce, stovetop bacon green beans bring a savory vegetable, and homemade baked beans round out a casual spread. A fried egg on top turns leftovers into brunch.

How to Store and Reheat Smoked Sausage Potato Casserole

Cool the casserole, cover it, and refrigerate for up to 3 days. Reheat single portions in the microwave, or warm a covered dish in the oven, until they reach 165 degrees F in the center. To freeze, assemble the casserole without baking, wrap it tightly, and freeze it, then thaw overnight in the refrigerator and bake until hot and bubbly.

Tips and Variations for Smoked Sausage Potato Casserole

Thaw the potatoes. Frozen hash browns release water, so thaw and pat them dry for a thicker casserole.

Slice evenly. Half inch rounds cook at the same pace and distribute evenly through the dish.

Mind the salt. Sausage, soup, and cheddar are all salty, so taste the sauce before adding more seasoning.

Watch the broiler. Cheese browns within seconds, so stay by the oven during the broil step.

Flag the allergens. The dish contains milk and wheat, and some sausages contain soy or other additives, so check every label.

Swap the sausage. Diced ham or cooked chicken sausage works in place of smoked sausage, using the same amount.

Add vegetables. Stir in thawed peas or diced bell pepper if you want color and a little freshness.

Check trusted guidance. For general advice on food safety and leftovers, read the Texas AgriLife Extension food safety guide.
