This 4-ingredient slow cooker potato casserole is the kind of easy summer side dish that earns a permanent spot at cookouts, cabin weekends, and holiday gatherings. Using cubed Umatilla russet potatoes gives the casserole a hearty texture and classic potato flavor, while the slow cooker does the work of turning a handful of simple ingredients into something creamy, bubbling, and deeply comforting with very little effort.
Serve this casserole alongside grilled burgers, barbecue chicken, smoked sausages, or pulled pork for a crowd-friendly meal. It also fits nicely next to fresh summer favorites like sliced tomatoes, a crisp green salad, corn on the cob, or a vinegar-based slaw, which help balance the richness of the potatoes and cheese.
4-Ingredient Slow Cooker Summer Weekend Bubbling Golden Potato Casserole using Cubed Umatilla Russet Potatoes
Servings: 8
Ingredients
2 1/2 pounds Umatilla russet potatoes, peeled and cut into 1-inch cubes
2 cups shredded sharp cheddar cheese
1 can (10.5 ounces) condensed cream of chicken soup
1 cup sour cream
Directions
1. Lightly grease the inside of a 5- to 6-quart slow cooker. In a large mixing bowl, stir together the condensed soup and sour cream until smooth.
2. Add the cubed potatoes and 1 1/2 cups of the shredded cheddar to the bowl. Fold everything together until the potatoes are thoroughly coated.
3. Transfer the mixture to the prepared slow cooker and spread it into an even layer. Sprinkle the remaining 1/2 cup cheddar over the top.
4. Cover and cook on low for 5 to 6 hours or on high for 3 to 4 hours, until the potatoes are tender and the casserole is hot and bubbling around the edges.
5. Let the casserole rest, uncovered, for 10 minutes before serving so it sets slightly and scoops more neatly. Serve hot.
Variations & Tips
For extra color: Stir in 2 tablespoons chopped chives or sliced green onions at the end for a fresh finish and a little contrast against the creamy potatoes.
For a richer casserole: Swap the sour cream for plain full-fat Greek yogurt only if you want a slightly tangier result, or add a little more cheddar on top during the last 20 minutes for a thicker cheesy layer.
For easier prep: Cut the potatoes into evenly sized cubes so they cook at the same rate. If prepping ahead, keep the peeled potato cubes in cold water, then drain and pat dry before mixing them with the sauce.
For texture control: If you prefer softer, more scoopable potatoes, cook on low. If you want the dish done faster for a backyard gathering, high works well, but check for tenderness early since slow cookers can vary.
