Ina Garten’s Mashed Potatoes with Sour Cream is a classic mashed potato recipe made extra creamy with butter, whole milk, and a generous amount of sour cream. The sour cream adds a subtle tang and velvety richness, making the potatoes fluffy, smooth, and full of flavor.
3 pounds Yukon Gold potatoes, peeled and cubed
1 cup sour cream
½ cup whole milk, warmed
½ cup unsalted butter, melted
1 teaspoon kosher salt (plus more to taste)
½ teaspoon black pepper
Optional: 2 cloves garlic, roasted or minced
Optional: ½ cup Parmesan or cream cheese for extra richness
Place potatoes in a large pot of salted water. Bring to a boil and cook for 15–20 minutes until fork-tender.
Drain well and return the potatoes to the warm pot. Let them sit for 1–2 minutes to evaporate excess moisture.
Mash using a potato masher or ricer until smooth and fluffy.
Mix in the melted butter, warm milk, sour cream, salt, and pepper. Stir gently until creamy and fully combined.
If the mash is too thick, add warm milk 1 tablespoon at a time until silky.
Transfer to a serving bowl and garnish with chives, parsley, or an extra pat of butter.
