This Instant Pot mashed potatoes with cabbage or Irish Colcannon recipe is a deliciously savory side dish made with mashed potatoes and cabbage. It's a wonderful twist on your regular mashed potatoes that you're going to love, and a great Vegetarian Pressure Cooker Recipe.
Place the potatoes, water, and 1 teaspoon salt into the Instant Pot. (I used a 6-quart Instant pot but you can use an 8 quart as well.) Place a steamer rack on top of the potatoes.
Close the lid. Press PRESSURE COOK and cook on HIGH for 5 minutes. Allow the pot to release pressure naturally for 10 minutes, and then release all remaining pressure.
Drain potatoes. Place potatoes, butter, 1.5 teaspoon salt, pepper, cream, and nutmeg into the bowl of a stand mixer and whip the potatoes until creamy (you can also use a hand mixer and whip the potatoes in the Instant Pot itself). You can also use a potato ricer or a potato masher if you'd rather.
