You can tailor these Amish-style slow cooker potatoes to your household while still keeping the spirit of a 4-ingredient, low-fuss dish. For a vegetarian version, use cream of mushroom or cream of celery soup instead of cream of chicken, and be sure your soup and cheese are made without animal-based rennet if that’s a concern. If you like a bit of tang, swap half of the cheddar for Monterey Jack or Colby-Jack, which melt very smoothly and create long, glossy cheese pulls. A smoked cheddar or smoked provolone will add a subtle campfire flavor without any extra work. To reduce richness slightly, use 1/4 cup butter and 1/4 cup low-sodium chicken broth in place of the full 1/2 cup butter; the texture will be a bit looser but still creamy. You can also stir in a handful of frozen peas or corn during the last 30 minutes of cooking if you want a pop of sweetness and color without adding much prep. For crispier edges, transfer the finished potatoes to a buttered baking dish and broil for 3 to 5 minutes until the top is deeply golden and lightly browned. Food safety tips: Always keep the potatoes frozen until you mix them; do not let them sit out for long periods before cooking. Use a slow cooker that is at least 4 quarts so the mixture heats evenly and quickly enough to pass through the food “danger zone” (40°F to 140°F) in a timely manner. Cook on LOW or HIGH as directed, and do not leave the slow cooker on the WARM setting for more than about 2 hours after cooking is complete. Refrigerate leftovers within 2 hours, in shallow containers so they cool quickly, and reheat thoroughly until steaming hot before serving.
