Mashed potatoes are no longer a chore with these Instant Pot mashed potatoes. They are a snap to fix because the pressure cooker cuts the cooking time in half. These creamy mashed potatoes took under 20 minutes to cook and mix using the Instant Pot electric pressure cooker. If you don't have an Instant Pot or similar multi-cooker, another brand of pressure cooker will work as well. Just follow the manufacturer's guidelines for setting and releasing steam.

Expert Tips

  • This recipe is made with red-skinned potatoes which are low in starch, or "waxy." For fluffier mashed potatoes, use russets or baking potatoes, which are high in starch, or use a medium starch potato such as Yukon gold or long whites.

Variations

  • Replace the butter with ghee, olive oil, or coconut oil.

  • Replace the cream or milk with coconut milk or broth.

  • Replace half of the potatoes with cauliflower for a lighter mash lower in carbs.

  • Add 1 to 2 cups of chopped cooked cabbage or kale to the pot for a traditional Irish-style colcannon.

  • Replace one-third to one-half of the potatoes with peeled and cubed rutabagas for delicious mashed potato and rutabaga combination.
