What You’ll Need — Ingredients for Garlic Mashed Potatoes with Sour Cream

• Yukon Gold potatoes (2 lb) — Their thin skins and buttery texture make for a naturally creamy mash; peeling is optional if you prefer texture and color.
• Garlic (4 cloves) — Use fresh garlic for the best aroma; roast for a sweeter, nutty flavor or sauté for a brighter garlic note.
• Sour cream (1/2 cup) — Adds tang and richness that keeps the mash from tasting one-note.
• Unsalted butter (1/3 cup) — Adds silky richness; use more or less depending on how decadent you want the dish.
• Whole milk (1/4 cup) — Thins the potatoes to the ideal texture; you can swap for cream or a non-dairy milk if needed.
• Kosher salt (1 tsp) — For the cooking water and final seasoning; it elevates all flavors.
• Freshly ground black pepper (1/4 tsp) — Adds balance and a gentle warmth.
• Chopped chives (2 tbsp) — Bright, fresh garnish that adds color and a subtle oniony lift.
• Optional: extra butter or olive oil — For finishing or for those who prefer an even richer mash.

Step-by-Step Guide to Making These Garlic Mashed Potatoes with Sour Cream

1. Prep the potatoes: Peel if you like, then cut the potatoes into roughly 1- to 1 1/2-inch pieces so they cook evenly. Place them in a large pot and cover with cold water — starting with cold water ensures even cooking.
2. Salt the water: Add a teaspoon of kosher salt to the pot. This seasons the potatoes from the inside out as they cook.
3. Cook until tender: Bring to a boil, then reduce to a simmer. Cook until a fork slides easily into the potatoes, usually 12–15 minutes depending on the size.
4. Prepare the garlic: While the potatoes cook, mince the garlic or roast whole cloves. For a brighter garlic flavor, briefly sauté minced garlic in a tablespoon of butter over low heat for 1–2 minutes. For a milder, sweeter garlic note, roast peeled garlic cloves at 400°F (200°C) wrapped in foil with a drizzle of oil for 25–30 minutes, then mash.
5. Warm butter and milk: Gently warm the butter and milk together just until the butter melts. Warm dairy blends seamlessly into the hot potatoes and keeps the mash from cooling down.
6. Drain and return: Drain the potatoes well and return them to the warm pot. Let them sit over low heat for about a minute to evaporate excess moisture.
7. Mash: Use a potato masher, ricer, or a food mill to mash the potatoes until mostly smooth. If you prefer a very creamy texture, a ricer or food mill is the best tool. Avoid overmixing with a high-speed mixer to prevent a gluey texture.
8. Combine with dairy and garlic: Pour in the warm butter-milk mixture, the sour cream, and the prepared garlic. Stir gently until the potatoes are creamy and well combined. Add more milk or sour cream to reach your desired consistency.
9. Season and finish: Taste and season with additional salt and freshly ground black pepper. Fold in chopped chives and finish with an extra pat of butter or a drizzle of olive oil if desired.
10. Serve warm: Spoon into a warmed serving bowl, garnish with a few more chives, and serve immediately for the best texture.

Timing & Preparation Details

• Active prep time: About 15 minutes to peel and cut the potatoes and prepare garlic.
• Cook time: Roughly 12–15 minutes to boil potatoes until fork-tender.
• Total time: Around 30–35 minutes from start to finish, depending on garlic method (roasting adds 20–30 minutes).
• Make-ahead: You can cook the potatoes in advance and refrigerate. Rewarm gently with extra milk or butter and stir in the sour cream right before serving to refresh texture.
• When to serve: Best served immediately while hot and fluffy; if holding, keep covered in a 200°F (95°C) oven for up to 20–30 minutes.

Answers to Common Questions

Can I use russet potatoes instead of Yukon Gold?

Yes — russets will work and create a fluffy mash, but they can be slightly drier and starchy. Yukon Golds typically give a naturally creamier, richer texture without needing as much butter or dairy.

Should I roast or sauté the garlic?

Both methods are delicious: sautéed garlic is brighter and more assertive, while roasted garlic is sweet, mellow, and almost buttery. Choose based on whether you want a stronger garlic bite or a softer, milder flavor.

How can I make these potatoes lighter or dairy-free?

To lighten them, reduce the butter and use low-fat sour cream or Greek yogurt. For dairy-free, use a plant-based butter and unsweetened non-dairy milk, and swap sour cream for a dairy-free alternative or plain, thick dairy-free yogurt. Keep in mind the texture and flavor will shift slightly.

There you have it — a simple, comforting recipe for Garlic Mashed Potatoes with Sour Cream that’s easy to make and easy to love. The flavors are familiar but elevated, and the technique is forgiving: taste, adjust, and make it your own. Enjoy sharing this cozy side with family and friends.

Ingredients

  

• 2 lb Yukon Gold potatoes
• 4 cloves garlic
• 1/2 cup sour cream
• 1/3 cup unsalted butter
• 1/4 cup whole milk
• 1 tsp kosher salt
• 1/4 tsp freshly ground black pepper
• 2 tbsp chopped chives
• optional extra butter or olive oil

Instructions

 

• Prepare the potatoes: Peel (optional) and cut potatoes into even 1- to 1 1/2-inch chunks so they cook uniformly.
• Salt the water: Place potatoes in a large pot and cover with cold water by about an inch. Add a teaspoon of kosher salt to the water.
• Bring to a boil and simmer: Bring to a gentle boil, then reduce to a simmer. Cook until potatoes are fork-tender, about 12–15 minutes depending on size.
• Meanwhile prepare the garlic: While potatoes cook, heat a small skillet over medium-low heat with a tablespoon of butter or oil and gently sauté minced or thinly sliced garlic until fragrant and soft (about 1–2 minutes). Alternatively, roast whole garlic cloves for a sweeter, milder flavor.
• Warm the dairy: In a small saucepan or microwave-safe bowl, warm the butter and milk together until the butter is melted and the mixture is warm but not boiling. This prevents cooling the potatoes when mixed.
• Drain and return potatoes: Drain potatoes thoroughly and return them to the warm pot. Let them sit for a minute to allow excess moisture to evaporate.
• Mash: Mash the potatoes using a potato masher, ricer, or hand mixer on low speed until mostly smooth. For the creamiest texture, a ricer or food mill works best.
• Add dairy and garlic: Stir in the warm butter and milk mixture, the sour cream, and the sautéed or roasted garlic. Mix until fully combined and creamy. Adjust the amount of milk or sour cream to reach your desired consistency.
• Season and finish: Taste and add additional salt and pepper as needed. Fold in chopped chives and, if desired, a pat of butter on top for presentation.
• Serve: Transfer to a warmed serving bowl and serve immediately while hot, or keep covered in a low oven (200°F/95°C) for up to 20–30 minutes.
