These potato cakes make a wonderful appetizer, especially for the holidays. Top them with an array of ingredients, from apples and sage to a red pepper aioli. With a crispy exterior and creamy center, these potato cakes will be the star of any gathering. For a colorful twist, try this recipe with purple potatoes.
Bring a large pot of water to a boil. Add potatoes and cook until fork-tender, 20 to 25 minutes. Drain and transfer to a large bowl; set aside to cool for 15 minutes.
Mash the potatoes with a potato masher. Add egg, butter and salt; mix well. Form 1/4-cup portions of the mixture into 3-inch-diameter cakes. Place the cakes on a baking sheet or tray and refrigerate for 15 minutes.
Transfer the potato cakes to the basket of an air fryer; coat with cooking spray. Cook at 400℉, flipping once, until golden brown and edges are crisp, 12 to 16 minutes. Top as desired (see Tip).
