This recipe gives you everything you want in a dish of mashed potatoes: supreme creaminess from both butter and sour cream, a deep potato flavor, a little Parmesan for a salty tang, and chives for color and freshness. That said, if you want to bring the fat content down, you can use less butter (as little as 2 tablespoons will still work). But don’t skimp on the sour cream, which is necessary for both flavor and texture.
1 tablespoon plus 1 teaspoon kosher salt
3 pounds Yukon Gold potatoes, peeled and cut into 1-inch chunks
5 tablespoons unsalted butter, at room temperature
1 cup sour cream, at room temperature
¼ teaspoon freshly ground black pepper
3 tablespoons finely chopped fresh chives
⅓ cup freshly grated Parmesan cheese, or to taste
Put 1 cup of warm water and the 1 tablespoon salt in the pressure cooker and stir until the salt dissolves. Insert the steamer basket and place the potatoes in the basket.
Cover, and cook on high pressure for 8 minutes. Release the pressure manually.
Transfer the potatoes to a bowl. Add the butter, sour cream, remaining 1 teaspoon salt, and the pepper and use a potato masher or fork to mash everything together. Add the chives and mix well. Adjust the seasoning to taste, if necessary. Sprinkle with the Parmesan cheese just before serving.
