How to Make Slow Cooker Potato Casserole
1. Make the Creamy Sauce
Lightly grease the inside of a slow cooker. In a large bowl, combine the cream of chicken soup, sour cream, and 1½ cups of shredded cheddar cheese.
2. Add the Potatoes
Fold the sliced potatoes into the creamy mixture until they’re evenly coated. Transfer everything to the slow cooker and spread into an even layer.
3. Slow Cook
Cover and cook on LOW for 5–6 hours, or until the potatoes are tender and the edges are hot and bubbling.
4. Add More Cheese
Sprinkle the remaining ½ cup cheddar cheese over the top. Cover and cook for another 10–15 minutes, just until the cheese melts.
Serve warm directly from the slow cooker.
Tips for the Best Potato Casserole
Keep the slices even: Uniform potato slices help everything cook at the same rate.
Check the center: Potatoes can vary in thickness, so make sure the center is completely tender before serving.
Don’t overcook: Once the potatoes are tender, switch the slow cooker to warm if you’re waiting to serve.
Let it stay warm: If the casserole thickens while sitting, gently stir around the edges to loosen the creamy sauce.
Easy Variations
Change the Cheese
Sharp cheddar gives this casserole its classic flavor, but Colby Jack, Monterey Jack, or a cheddar blend can also work well.
Add More Seasoning
For extra savory flavor, add a little black pepper, minced onion, or garlic powder.
Make It for a Potluck
Keep the casserole in the slow cooker on the warm setting for a short serving window. This makes it especially convenient for luncheons and buffet-style meals.
