This 5-Ingredient Slow Cooker Amish Relatives' Casserole is the kind of practical supper that earns a permanent place in a busy cook’s rotation. Built around simple pantry and refrigerator staples, it leans into the old-fashioned, economical spirit often associated with Amish-style home cooking: hearty, filling, and designed to feed people well with very little fuss. The slow cooker does nearly all the work, turning humble potato wedges, cream soup, and savory seasonings into a rich, comforting casserole with minimal prep and easy cleanup.
Serve this casserole with a crisp green salad, buttered green beans, or simple steamed broccoli to balance its richness. It also pairs nicely with baked ham, roast chicken, or sausage if you want to round it out into a larger spread, though it is substantial enough to stand on its own for a casual family dinner. A spoonful of applesauce or a side of pickles also works surprisingly well with the creamy, savory flavors.
5-Ingredient Slow Cooker Amish Relatives' Casserole
Servings: 6
Ingredients
2 pounds russet potatoes, scrubbed and cut into thick wedges
1 can (10.5 ounces) condensed cream of mushroom soup
1 cup sour cream
1 packet (1 ounce) onion soup mix
2 cups shredded cheddar cheese
Directions
1. Lightly grease the insert of a 5- to 6-quart slow cooker. Cut the scrubbed potatoes into thick wedges so they cook evenly and hold their shape during the long cooking time.
2. In a medium bowl, stir together the condensed cream of mushroom soup, sour cream, and onion soup mix until smooth and evenly combined.
3. Add half of the potato wedges to the slow cooker, spoon over half of the creamy mixture, and sprinkle with half of the shredded cheddar. Repeat with the remaining potatoes, creamy mixture, and cheese.
4. Cover and cook on low for 6 to 7 hours or on high for 3 to 4 hours, until the potatoes are tender and the casserole is bubbling around the edges.
5. Turn the slow cooker off, let the casserole rest uncovered for about 10 minutes to thicken slightly, then spoon it into bowls or onto plates and serve hot.
Variations & Tips
Add protein: For a more complete one-pot dinner, layer in 2 cups of diced cooked ham or browned sausage between the potatoes. This gives the casserole a heartier, supper-ready feel without changing the method.
Change the soup: Cream of chicken or cream of celery soup can be swapped in for the cream of mushroom if that is what you have on hand. Each one changes the flavor a bit, but the casserole stays creamy and dependable.
For better texture: If you like more defined wedges, avoid cutting the potatoes too thin. Thick, evenly sized pieces hold up best in the slow cooker and keep the casserole from turning overly soft.
Extra color on top: If your slow cooker insert is broiler-safe or if you transfer the finished casserole to a baking dish, a few minutes under the broiler can add appealing browned spots to the cheese just before serving.
Make-ahead tip: You can mix the sauce the night before and keep the potatoes in cold water in the refrigerator. Drain and dry the wedges well before assembling so the casserole does not become watery.
