Ingredients
- 1 (32 oz) bag frozen hashbrowns
- 1 package kielbasa, diced (or use smoked sausage)
- 1 small onion, diced
- 2 cups shredded cheddar cheese, divided
- ½ cup sour cream
- ½ cup milk
- 1 (10 oz) can cream of mushroom or cream of chicken soup
- Salt, pepper, garlic powder, onion powder (optional but recommended)
Optional Add-Ins & Variations
- Add frozen peas or bell peppers for veggies
- Swap kielbasa for leftover ham or ground beef
- Use Monterey Jack or pepper jack cheese for a different flavor
- Top with French-fried onions or crushed Ritz crackers for crunch after cooking
How to Make It
🥣 Step 1: Dump the Base
Grease your slow cooker.
Add the hashbrowns, diced kielbasa, onion, and 1½ cups of the shredded cheese. Stir to combine.
🧄 Step 2: Make the Creamy Mixture
In a bowl, whisk together the cream of soup, milk, sour cream, and seasonings to taste (salt, pepper, garlic powder, onion powder). Pour evenly over the hashbrown mixture in the slow cooker.
🧀 Step 3: Top & Cook
Sprinkle the remaining ½ cup of cheese over the top.
Cover and cook on LOW for 6 hours or HIGH for 3–4 hours, until everything is hot, bubbly, and the edges start to get golden.
Tips for Success
- Don’t thaw the hashbrowns—they cook perfectly from frozen.
- Use block cheese and shred it yourself for best meltability.
- Crispier top? Transfer to a baking dish and broil for 3–5 minutes before serving (optional).
