Creamy Garlic Parmesan Mashed Potatoes

Creamy Garlic Parmesan Mashed Potatoes turn a classic side into something extra comforting without making it complicated. Yukon Gold potatoes create a naturally buttery base, while warm milk, sour cream, and garlic-infused butter give every spoonful a smooth, rich texture. Freshly grated Parmesan adds savory depth, and chives bring just enough freshness to balance the creamy finish.

The method is simple but thoughtful. Starting the potatoes in cold salted water helps them cook evenly, while a quick return to the warm pot removes excess moisture. Then, the dairy is folded in gently so the potatoes stay fluffy instead of becoming heavy or gummy. Finished with melted butter and fresh chives, this easy mashed potato recipe works beautifully beside roast chicken, steak, holiday turkey, or a cozy vegetarian main. It is familiar comfort food with a polished, flavorful finish.

Recipe Yield: 8 servings

INGREDIENTS

3 lb Yukon Gold potatoes, peeled and cut into 1 1/2-inch chunks
1/2 cup whole milk, warmed, plus more as needed
1/2 cup full-fat sour cream, room temperature
1/4 cup unsalted butter, plus more for serving
3 large garlic cloves, finely minced
1/2 cup freshly grated Parmesan cheese
1/2 cup chopped fresh chives, divided
1 tbsp kosher salt, divided, plus more to taste
1/2 tsp black pepper

INSTRUCTIONS

1. Prepare the potatoes:
Place the potatoes in a large pot and cover with cold water by about 1 inch. Add 2 tsp salt and bring to a boil over medium-high heat. Reduce to a gentle simmer and cook for 15–20 minutes, until very tender and easily pierced with a fork.

2. Drain and dry:
Drain the potatoes thoroughly. Return them to the pot over low heat for 1–2 minutes, gently shaking the pot once or twice, until the excess moisture evaporates. Remove from the heat.

3. Infuse the garlic butter:
Meanwhile, melt the butter in a small saucepan over low heat. Add the garlic and cook for 1–2 minutes, stirring frequently, until fragrant and softened but not browned. Stir in the warm milk and heat gently without simmering.

4. Mash and combine:
Mash the hot potatoes with a potato masher or pass them through a ricer. Gradually fold in the warm garlic-butter mixture. Then, gently mix in the sour cream, Parmesan, remaining 1 tsp salt, and black pepper just until creamy. Add another splash of warm milk if needed.

5. Finish and serve:
Fold in the chives, reserving about 1 tbsp for garnish. Transfer the potatoes to a serving bowl, swirl the top, and finish with a small pat of butter and the remaining chives. Serve hot.

Helpful Tips to Perfect This Recipe

• Avoid overmixing: Once the potatoes are smooth and creamy, stop stirring. Working them too aggressively can release excess starch and create a gummy texture.
• Grate the Parmesan finely: Freshly grated Parmesan melts more evenly and gives the mashed potatoes a smoother finish than coarse or pre-shredded cheese.
• Adjust just before serving: Mashed potatoes naturally thicken as they rest. Fold in warm milk, 1 tbsp at a time, if they need loosening before serving.
