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. Place a steamer rack on top of the potatoes.
Place cabbage in a 6 x 3 container. Place the container on top of the steamer rack.
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.
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).
