Step-by-step overview
This Slow Cooker Sausage and Potato Casserole combines the ingredients in layers. In your slow cooker, you’ll mix the hash browns, sausage, onions, and cheese. Then, you’ll prepare a creamy soup mixture that gets poured over everything. After sprinkling some more cheese on top, you let it cook until perfectly soft and flavorful.
What you’ll need
- 1 – 32 oz. bag of hash browns or may substitute fresh diced potatoes
- 14 oz. kielbasa cut into small pieces
- 1 small onion diced
- 2 1/2 cups shredded cheddar cheese
- 10.5 oz can cream of chicken or mushroom soup
- 1/2 cup sour cream
- Salt and pepper to taste
Ingredient notes & swaps
- Hash browns: Fresh diced potatoes can be used but may require adjustments in cooking time.
- Sausage: Kielbasa provides a smoky flavor, but you can use any sausage you prefer.
- Cheese: Feel free to experiment with different types of cheese, like Monterey Jack or pepper jack for a kick.
Cooking method
To create this delightful casserole, follow these simple steps:
- Start by combining the hash browns, kielbasa, diced onion, and 2 cups of shredded cheddar cheese in a greased slow cooker. Some find it helpful to sauté the sausage and onions for added flavor before placing them in the slow cooker.
- In a separate bowl, mix the cream of chicken or mushroom soup, sour cream, salt, and pepper to create a creamy mixture.
- Pour this creamy mixture over the hash brown mix, stirring gently to combine.
- Sprinkle the remaining cheddar cheese over the top.
- Cook on low for 6-8 hours or on high for 4-5 hours, until the potatoes and onions are cooked through. Be careful not to overcook the potatoes to maintain their texture.
Pro Tip: If you’re using fresh diced potatoes instead of hash browns, check for tenderness closer to the end of the cooking time to avoid mushiness.
You will know the casserole is done when everything is cooked through. As it bubbles away, the aroma of melting cheese and savory sausage will make your kitchen feel like home.

Helpful cooking tips
- If you sauté the sausage and onions first, it can add a depth of flavor but is optional if you’re short on time.
- For creaminess, ensure that your soup mix is well combined before pouring it over the hash browns.
- You can add a splash of Worcestershire sauce for an extra layer of flavor if desired.
- Keep an eye on the cooking time, especially if you substituted fresh potatoes, as they may need a bit longer.
Serving suggestions
This casserole is a stand-alone dish, offering comfort all on its own. However, pairing it with a side salad can add freshness to the meal. Consider garnishing with chopped scallions or parsley for an extra pop of color. A dollop of sour cream at serving can enhance creaminess, making each bite even more indulgent.
Storage & reheating tips
Once cooled, leftovers can be stored in an airtight container in the refrigerator. This dish holds up well for several days, allowing you to enjoy the leftovers for quick meals. If you wish to freeze the casserole, portion it into smaller containers that can be easily reheated. Ensure you let it cool completely before placing it in the freezer.
Refrigerate leftovers within 2 hours; reheat until steaming hot.
How to fix common issues
If your casserole turns out dry, adding a splash of broth or milk when reheating can help restore moisture. If it’s too bland, a pinch of garlic powder or additional salt can enhance the flavor. To avoid vegetables turning mushy, be careful not to overcook; they should be tender but still maintain a bit of bite.
Recipe variations
For those looking to spice things up, consider adding diced bell peppers or mushrooms to the casserole mix. You can also swap out the kielbasa for a different protein, such as chicken or ground beef. For a vegetarian option, simply omit the sausage and increase the amount of vegetables, or add beans for added protein.
