This recipe for The Best Buttery Mashed Potatoes walks you through an easy, reliable method to get that tender, luxurious texture every time — whether you’re feeding a hungry family on a weeknight or rounding out a festive holiday plate.

Why You’ll Fall for This Version of The Best Buttery Mashed Potatoes

What makes these mashed potatoes stand out is the balance of technique and ingredients. Using Yukon Gold potatoes gives you a naturally buttery flavor and a creamier mouthfeel than some other types. Warming the milk and butter before adding them to the potatoes keeps the mash silky instead of gluey, and finishing with sour cream adds richness without weighing the dish down. The result is an indulgent, fluffy mash that feels special without being complicated.

Ingredients You’ll Need for The Best Buttery Mashed Potatoes

• Yukon Gold potatoes (2 lb) — These provide a buttery flavor and creamier texture; you can leave the skins on for texture or peel for classic smoothness.
• Kosher salt (1 tsp for boiling) — Salting the cooking water seasons the potatoes from within so they don’t taste flat.
• Whole milk (1/2 cup) — Adds moisture and creaminess; warming it prevents cooling the potatoes and helps it absorb better.
• Unsalted butter (4 tbsp) — The key to flavor and satin-smooth texture; use salted if you prefer but reduce added salt.
• Sour cream (2 tbsp) — Gives a gentle tang and extra creaminess while helping keep the mash light.
• Freshly ground black pepper (1/4 tsp) — Balances the richness with mild heat.
• Chives, chopped (optional, 1 tbsp) — Fresh garnish that adds color and a mild oniony lift.

Step-by-Step Guide to Making The Best Buttery Mashed Potatoes

1. Prepare the potatoes: Scrub them clean. If you prefer no skins, peel them, then cut into roughly 1½–2-inch chunks so they cook evenly.
2. Start in cold water: Place the potatoes in a large pot and cover with cold water by about an inch. Add the kosher salt. Starting with cold water ensures even cooking.
3. Cook until tender: Bring to a gentle boil, then reduce to a simmer. Cook for about 15–20 minutes, or until a fork slides through the largest pieces without resistance.
4. Warm milk and butter: While potatoes simmer, warm the milk and butter together until the butter melts and the milk is hot. This step prevents shocking the potatoes and helps the mash stay creamy.
5. Drain and dry: Drain the potatoes thoroughly. Return them to the warm pot and let them sit for a minute over low heat to steam off any excess water — this keeps the mash from becoming watery.
6. Mash to your preferred texture: Use a ricer for the smoothest result or a masher for a bit more rustic texture. Avoid electric mixers which can make potatoes gummy if overworked.
7. Add dairy gradually: Pour in the warm milk-butter mixture a little at a time, folding it into the potatoes until you reach a silky consistency. Add the sour cream and mix gently.
8. Season and finish: Taste and adjust salt and pepper. Fold in chopped chives if using. Serve immediately with an extra pat of butter on top for sheen and flavor.
9. Keep warm if needed: If you need to hold the potatoes for a short while, keep them covered in a warm oven (about 200°F/95°C) or in a slow cooker on the warm setting.

Timing & Preparation Details for Smooth Success

• Active prep time: About 15 minutes (peeling, cutting, and warming dairy).
• Cook time: 15–20 minutes boiling, depending on chunk size.
• Total time: Roughly 30–40 minutes from start to finish.
• Holding: Keeps well for 2–3 hours in a warm oven or slow cooker; stir occasionally and add a splash of warmed milk if it begins to dry out.
• Ready to enjoy: Serve immediately for the fluffiest texture; the potatoes are at their best hot and freshly finished.

Helpful Questions People Ask

Can I make these ahead of time?

Yes. Prepare the mashed potatoes up to the point of finishing, then cool and refrigerate. Reheat gently in a low oven, on the stovetop, or in a slow cooker, stirring in a little warmed milk or butter to refresh the texture.

What if my potatoes turn out gluey?

Gluey potatoes are usually caused by overworking them, especially with an electric mixer. To avoid this, mash by hand or use a ricer, and stir gently when adding dairy. Also, starting with the right potatoes (Yukon Gold or a mix with Russet) helps.

Can I use milk substitutes or less butter?

Yes. Use half-and-half or cream for a richer finish, or a non-dairy milk plus a dairy-free butter if you need a vegan option (results will differ slightly). Reducing butter will make the mash less rich but still tasty — consider adding more sour cream or a drizzle of olive oil for flavor.

Ingredients

  

• 2 lb Yukon Gold potatoes
• 1 tsp Kosher salt (for boiling)
• 1/2 cup Whole milk
• 4 tbsp Unsalted butter
• 2 tbsp Sour cream
• 1/4 tsp Freshly ground black pepper
• 1 tbsp Chives, chopped (optional)

Instructions

 

• Scrub the potatoes well under cold water and, if desired, peel them. Cut into even 1½–2-inch chunks so they cook uniformly.
• Place the potato chunks in a large pot and cover with cold water by about 1 inch. Add 1 teaspoon kosher salt to the water.
• Bring the pot to a gentle boil over medium-high heat, then reduce to a simmer. Cook until the potatoes are tender when pierced with a fork, about 15–20 minutes depending on size.
• While the potatoes cook, warm the milk and butter together in a small saucepan or in the microwave until the butter is melted and the mixture is hot but not boiling.
• Drain the potatoes well in a colander, then return them to the warm pot. Allow them to sit for a minute over low heat to let excess moisture evaporate (shake the pot gently to prevent sticking).
• Mash the potatoes using a potato masher or ricer until mostly smooth. For the creamiest texture, use a ricer; for a bit more body, use a masher.
• Gradually stir in the warm milk and butter mixture, then fold in the sour cream. Mix until the potatoes are silky and you reach your preferred consistency.
• Taste and season with additional salt and freshly ground black pepper as needed. Stir in chopped chives if using.
• Serve immediately, topped with an extra pat of butter and a sprinkle of chives. If holding before serving, keep warm in a covered dish or in a low oven (200°F/95°C).
