These Slow Cooker Scalloped Potatoes are creamy, cheesy, and made with just four main ingredients. Thin-sliced potatoes, heavy cream, sharp cheddar, and onion soup mix cook into an easy side dish without using the oven.
Store leftovers in a covered container in the refrigerator for up to 3 to 4 days, with three days being best. Reheat portions gently in the microwave until hot, or reheat a larger amount covered in the oven. Sliced potatoes can be prepared ahead and kept covered in cold water in the refrigerator for a few hours; drain and pat them dry before layering.
