3 Ingredients Buttermilk Baked Potatoes

3-Ingredient Buttermilk Baked Potatoes are a simple yet incredibly comforting dish made with just potatoes, buttermilk, and butter (or cheese). The potatoes are baked until tender, then infused with creamy, tangy buttermilk that soaks into every bite. As they finish baking, the tops turn golden and slightly crispy while the inside stays soft and fluffy.
