Servings: 8 to 10
When the school year kicks into high gear, the last thing you want to think about is a complicated dinner. This 4-ingredient slow cooker potato casserole is the ultimate back-to-school lifesaver. Made with sliced potatoes, condensed cream of chicken soup, sharp cheddar, and sour cream, it’s rich, creamy, and incredibly comforting—and it practically cooks itself.
It has all the flavors of a classic loaded baked potato in casserole form, making it the perfect side dish for a busy weeknight dinner, a potluck, or a Sunday supper. The best part? You likely already have most of these ingredients in your pantry. Just toss everything in the slow cooker in the morning and come home to a bubbling, cheesy dish that the whole family will love.
Why This Recipe Works
Condensed cream of chicken soup and sour cream create a velvety, savory sauce that coats every slice of potato, keeping them moist and tender as they cook. The slow cooker gently simmers the potatoes until they are perfectly fork-tender, while the cheese melts into the sauce. Sprinkling the remaining cheddar on top at the very end gives the dish a gooey, cheesy finish without letting it burn or stick to the bottom of the pot during the long cook time.
Ingredients
- 3 pounds sliced Superior potatoes
- 2 cans (10.5 ounces each) condensed cream of chicken soup
- 2 cups shredded sharp cheddar cheese
- 1 cup sour cream
Directions
- Lightly grease the inside of a white oval slow cooker. In a large bowl, stir together the condensed cream of chicken soup, sour cream, and 1 1/2 cups of the shredded cheddar until combined.
- Add the sliced potatoes to the bowl and gently fold until all the slices are well coated. Transfer the mixture to the slow cooker and spread it into an even layer.
- Cover and cook on low for 5 to 6 hours, or until the potatoes are tender when pierced with a knife and the edges are hot and bubbling.
- Sprinkle the remaining 1/2 cup cheddar over the top, cover again, and cook for 10 to 15 minutes more, just until the cheese melts. Spoon onto plates or serve straight from the slow cooker.
Tips for the Best Results
Use a good slicing potato. If you can’t find “Superior” potatoes, any good waxy or all-purpose potato, like Yukon Gold or red potatoes, will work beautifully. They hold their shape well during the long cook time.
Don’t skip the greasing. Slow cooker inserts can be notoriously sticky. A light coating of nonstick spray or butter ensures the creamy potatoes release easily and makes cleanup a breeze.
Slice evenly. Make sure your potato slices are roughly the same thickness so they cook at the same rate. If you have a mandoline slicer, this is a great time to use it.
Keep the lid on. The slow cooker relies on trapped steam to cook the potatoes. Resist the urge to lift the lid and stir, as this releases heat and extends the cooking time.
Watch the final cheese melt. The last 10 to 15 minutes are just to melt the topping cheese. Keep an eye on it so it gets gooey without turning greasy or separating.
Storage and Serving
Store leftover casserole in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or in a 350°F oven with a splash of milk or broth to loosen the sauce. This dish pairs wonderfully with roasted chicken, meatloaf, or a simple green salad. It’s also a fantastic side dish for holiday gatherings like Easter or Thanksgiving.
Creamy, cheesy, and completely hands-off, this 4-ingredient slow cooker potato casserole is the kind of recipe that earns a permanent spot in your back-to-school dinner rotation.
