Learn how to make mashed potatoes with our step-by-step instructions and 5 tips for the best, fluffy mashed potatoes.

My grandmother used to make the most amazing smooth-as-silk mashed potatoes that were never gummy, lumpy or dry. What was her secret? Tons of butter and whole milk. I would love to follow in her footsteps and make her recipe as is, but I would have to spend the next month on the treadmill working those potatoes off.

We've tested and developed many mashed potato recipes in the TheListMagazine Test Kitchen, discovering a few tips to getting the classic fluffy result without dousing them in a sea of melted butter and heavy cream.

How you like your mashed ­potatoes comes down to personal preference. Maybe you like them chunky: unpeeled and mashed by hand. Or you’re a connoisseur of silky-smooth whipped potatoes. And perhaps you’re looking for a way to jazz up this holiday must-have with more flavor? Whatever the case, we’ve got you covered. Here's everything you need to know for making the ultimate mashed potatoes: what potatoes to buy, how to cook them and tips for achieving your desired mashed-­potato texture. Plus find some of our new favorite things to stir into mashers, like roasted garlic, sautéed leeks or a touch of brown butter. Read on: your best mashed potatoes await.

To make great mashed potatoes, follow the steps below. Then season the potatoes with flavorings of your choice. Makes: 8 servings, about 3/4 cup each.

Step 1

To serve about 8 people, start with 3 pounds Yukon Gold potatoes (about 12 medium). The potato peel offers nutritional benefits like fiber and potassium. Leave it on for rustic mashed potatoes, but peel it off if you want to whip or rice them for a smoother texture. Then cut potatoes into 2-inch chunks.

Step 2

Place the potatoes and 1 tablespoon salt in a large heavy saucepan; add cold water to cover the potatoes by 2 inches; bring to a boil. Reduce heat to a simmer, cover and cook until the potatoes are very tender, 10 to 15 minutes. Drain well.

Step 3

Transfer the potatoes to a large bowl and mash with a potato masher, ricer or electric mixer. What tool should you use to mash?

Use a Potato Masher for Rustic Mashed Potatoes

This is the method to use if you leave the peel on your potatoes. Mash with a potato masher until they’re as lumpy (or smooth) as you like. No masher? No problem. Use a large fork with sturdy prongs and mash the potatoes against the side of the bowl.

Use a Ricer for Smooth Mashed Potatoes

Want 100%-lump-free mashed potatoes? Use a ricer. A ricer pushes the potato through a grid, making small crumbles that resemble rice. They practically melt together as you stir in flavorings, resulting in a velvety-smooth texture.

Use an Electric Mixer for Whipped Mashed Potatoes

Light and airy mashed pota­toes result from using an electric mixer. The mixer breaks up potatoes and whips air into them at the same time. Don’t go overboard­—the mechanical “masher” can make potatoes gummy; stop whipping as soon as they’re smooth.

Step 4

Stir your favorite flavorings into the hot potatoes just until combined. Season with black or white pepper to taste.

Roasted Mushrooms: Toss 5 cups chopped mixed mushrooms and 3 tablespoons chopped shallots with 1/4 cup extra-virgin olive oil, 1/4 teaspoon salt and pepper. Spread on a baking sheet. Roast at 425°F until brown, 20 to 30 minutes. Remove from oven; stir in 2 tablespoons dry sherry.

Sautéed Leeks: Heat 2 tablespoons butter in a large skillet over medium heat. Add 4 cups thinly sliced leeks (whites and greens from about 2 large leeks). Cook, stirring, until soft and beginning to brown, 4 to 8 minutes.

Olive Oil & Herbs: Crush 1 tablespoon each chopped fresh sage, thyme and rosemary, 1/4 cup chopped fresh parsley, 1 clove minced garlic and a pinch each salt and pepper in a mortar and pestle until a paste forms. Stir in 1/4 cup extra-virgin olive oil.

Roasted Garlic: Slice the tips off 2 garlic heads, exposing the cloves, and place in a small baking dish. Drizzle with 2 tablespoons extra-virgin olive oil. Roast at 400°F until the garlic feels soft, 20 to 40 minutes, depending on size. Gently squeeze garlic cloves from the skins into potatoes.

Brown Butter: Melt 3 tablespoons butter in a small saucepan over medium heat. Continue heating until it starts bubbling; stir and cook, watching carefully so it doesn’t burn, until it turns golden brown, 2 to 4 minutes.

5 Tips for Perfect Classic, Fluffy Mashed Potatoes

1. Cook Potatoes Using the Right Method

Start them cold: Add potatoes to cold water and bring to a boil. The potatoes cook more evenly than if you add them to water that’s already boiling. Make sure that your potatoes are cut into equal sizes, too—big pieces and small pieces cook at different rates.

2. Don't Overcook or Undercook the Potatoes

Cooking the potatoes just right is key. If they're undercooked, you'll have pockets of crispy potato chunks—a big no-no for classic fluffy mashed potatoes. If you overcook them they disintegrate and your potatoes will be soupy. The specific cooking time depends on the size of your potato: a perfectly cooked piece of potato should give no resistance when cut with a knife, but shouldn't crumble into a million pieces.

3. Don't Overmix the Potatoes

Even if you've picked the right potatoes, overmixing mashed potatoes can lead to a stiff, chewy texture. Keep them fluffy by mashing them through a ricer for smooth potatoes or using a hand-held masher for chunkier potatoes. This limits the amount that the potatoes are processed so the starches stay intact. If they're overwhipped, the starches break down further and give you a sticky result.

4. Pick the Right Potato

There are plenty of different kinds of potatoes out there, but all fall into three categories: waxy, starchy and all-purpose. When you're talking mashed potatoes, Yukon Gold is best. They have less starch than a “floury” potato (like russets), but more than a “waxy” potato (like a red potato). Not enough starch and potatoes are dry; too much, they’re gummy.

5. Serve Them Hot

Mashed potatoes lose their luster as they sit. Try to serve them right away after finishing them. To keep mashed potatoes warm until you’re ready to serve, transfer to a slow cooker, cover and keep on the “warm” setting for up to 2 hours. If you make them ahead and want to reheat them, do so slowly with the help of a double boiler. This way, they won't burn if they come in contact with the bottom of a saucepan on the stove. And since you won't be worried about burning, you can stir them less, which will prevent them from becoming gummy.
