Crockpot Cheesy Potatoes are loaded with cheddar, Parmesan, and sour cream for a creamy, comforting side dish. Just 10 minutes of prep and your slow cooker does all the work. Perfect for holidays, potlucks, or easy family dinners.
Lightly spray the insert of your slow cooker with nonstick cooking spray.
Add the frozen diced potatoes, sour cream, cream of chicken soup, diced onion, Parmesan cheese, and 2 cups of the cheddar cheese to the slow cooker. Season with salt, pepper, and garlic powder. Stir until the potatoes are completely coated.
Cover and cook on LOW for 4 hours. Do not cook on high, as the dairy will curdle and the cheese can burn onto the sides of the slow cooker.
Stir the mixture until the cheese sauce is smooth and creamy. Switch the slow cooker to warm.
Sprinkle the remaining 1/2 cup of cheddar cheese on top. Cover and let sit for 10 to 15 minutes, or until the cheese is melted.
Garnish with fresh minced chives and serve immediately.
Notes
Cook on LOW only. High heat will curdle the dairy and can burn the cheese onto the slow cooker.
Grate cheese from the block. Pre-shredded cheese has anti-caking agents that prevent smooth melting.
Use frozen diced potatoes, not shredded. Shredded potatoes will turn mushy. No need to thaw frozen cubed potatoes before adding.
Fresh potatoes: Use about 6 cups of peeled and diced russet potatoes. Consider par-boiling for a few minutes first since frozen potatoes are already partially cooked.
Condensation tip: If moisture builds up on the lid, lay a few paper towels across the top of the slow cooker before replacing the lid to absorb excess water.
Cream soup substitute: Cream of mushroom soup works well, or make a quick homemade version with butter, flour, and chicken broth.
Make ahead: Combine everything in the slow cooker insert the night before and refrigerate. Add about 30 extra minutes of cook time.
Storage: Refrigerate leftovers in an airtight container for up to 3 to 4 days. Freeze for up to 3 months (texture may change slightly).
Reheat: Microwave at 50% power, stirring every 20 to 30 seconds. Or warm in a saucepan over low heat with a splash of milk.
Oven option: Mix everything together, pour into a greased 13x9-inch dish, cover with foil, and bake at 350°F for 45 minutes. Uncover, add cheese, and bake 10 to 15 more minutes.
