Description

This recipe for Cheesy Mashed Potatoes with Garlic & Sour Cream offers a creamy, flavorful twist on classic mashed potatoes. Yukon Gold potatoes are boiled with whole garlic cloves for a subtle garlic infusion, then mashed smooth and enriched with butter, warm milk, and cream. Cheddar and Parmesan cheeses create a rich, cheesy flavor, while sour cream adds a tangy creaminess. Finished with fresh chives, this comforting side dish is perfect for weeknight dinners or festive holiday meals.


Ingredients

Potatoes and Garlic

  • lbs Yukon Gold potatoes, peeled and cut into chunks
  • 4 cloves garlic, peeled

Dairy and Cheese

  • 4 tablespoons unsalted butter
  • ½ cup whole milk, warm
  • ½ cup heavy cream, warm
  • 1 cup shredded white cheddar cheese
  • ¼ cup grated Parmesan cheese
  • 2 tablespoons sour cream

Seasoning and Garnish

  • 1 teaspoon salt
  • ½ teaspoon ground black pepper
  • Chopped fresh chives, for garnish


Instructions

  1. Boil the potatoes and garlic: Place the peeled potato chunks and whole garlic cloves into a large pot. Cover with cold water, salted by about an inch above the potatoes. Bring to a boil over medium-high heat and cook for 15–20 minutes until the potatoes are very tender when pierced with a fork.
  2. Drain and dry for fluffier mash: Drain the potatoes and garlic well, then return them to the warm pot. Let them sit uncovered for 2–3 minutes to steam off excess moisture, which helps the mash absorb the dairy and become extra creamy.
  3. Mash until smooth: Using a potato masher, ricer, or hand mixer, mash the potatoes and garlic until smooth and fluffy without any large lumps.
  4. Stir in the dairy for creaminess: Add the butter, warm milk, and warm heavy cream to the mashed potatoes. Gently stir until everything is fully incorporated and the mixture is silky smooth. Warming the dairy prevents gumminess and keeps the potatoes light.
  5. Make them cheesy & tangy: Mix in the shredded cheddar cheese, grated Parmesan, and sour cream. Stir just until the cheeses melt and the potatoes become rich and velvety. Taste and adjust seasoning with salt and black pepper as needed.
  6. Finish and serve: Spoon the mashed potatoes into a serving bowl, top with a little melted butter and a sprinkle of chopped fresh chives. Serve hot as a comforting side dish suitable for weeknights or holiday meals.

Notes

  • For even creamier mashed potatoes, use a potato ricer or food mill instead of a masher.
  • Warming the milk and cream before adding prevents the potatoes from cooling down and becoming gummy.
  • Adjust garlic amount based on your preference for a stronger or milder garlic flavor.
  • Fresh chives add a nice pop of color and mild onion flavor but can be omitted if unavailable.
  • Leftovers can be refrigerated for up to 3 days and reheated gently with additional milk or cream if needed.
