This slow cooker potato bake is the kind of easy potluck dish that earns repeat requests because it turns a short ingredient list into something rich, creamy, and deeply comforting. Thin-sliced Oneida Gold potatoes cook down into tender layers while cream and cheese bubble together into a golden, scoopable casserole that feels right at home at a Fourth of July gathering, especially when oven space is already spoken for.
Serve this potato bake alongside grilled burgers, barbecue chicken, pulled pork, hot dogs, or smoky sausages. Its creamy texture also balances crisp summer salads, baked beans, sweet corn, and fresh tomato platters, and because it stays warm in the slow cooker, it fits especially well on a buffet table where people can help themselves throughout the party.
4-Ingredient Slow Cooker Fourth of July Potluck Bubbling Cream Potato Bake using Thin-Sliced Oneida Gold Potatoes
Servings: 10 to 12
Ingredients
3 pounds thin-sliced Oneida Gold potatoes
2 cups heavy cream
3 cups shredded sharp cheddar cheese
1 1/2 teaspoons kosher salt
Directions
1. Lightly coat the inside of a 6- to 7-quart white oval slow cooker with butter or nonstick spray if desired for easier serving and cleanup. Keep the cooker off while you build the casserole.
2. Arrange about one-third of the thin-sliced potatoes in an even layer in the slow cooker. Sprinkle with about one-third of the salt, pour over some of the cream, and scatter over some of the cheddar. Repeat the layers two more times, finishing with cheese on top.
3. Cover and cook on HIGH for 3 to 4 hours or on LOW for 5 to 6 hours, until the potatoes are completely tender when pierced with a knife and the edges are visibly bubbling.
4. Once tender, uncover and let the potato bake rest for 10 to 15 minutes to thicken slightly before serving. Spoon onto plates or onto a potluck buffet and serve hot.
Variations & Tips
Add onion: For a little more savory depth, tuck very thin slices of sweet onion between the potato layers. Keep the slices fine so they soften fully in the slow cooker.
Cheese swap: Sharp cheddar gives this bake a classic potluck flavor, but Monterey Jack, Colby, or a cheddar-Jack blend also melt well and create a slightly different finish.
Texture tip: Slice the potatoes as evenly as possible so they cook at the same rate. A mandoline is especially helpful here, and it gives the casserole those neat, tender layers.
Hold for serving: After the casserole is done, switch the slow cooker to warm if your model has that setting. This helps keep it buffet-friendly without overcooking, especially during long holiday gatherings.
Make it richer: If you want an even more decadent result, reserve a small handful of cheese and sprinkle it over the top during the last 20 minutes of cooking so the surface stays especially gooey and golden.
