There is comfort food, and then there are perfect mashed potatoes. The kind that are impossibly smooth and creamy, rich with butter and cream, seasoned just right. The kind that make you close your eyes and sigh with every bite. This is not just a side dish. This is the main event.
I have made thousands of batches of mashed potatoes over the years, and through all that testing, I have learned that the details really do matter. The type of potato, how you cook them, how much butter you add, and how you mash them all contribute to the final result. Get these right and you will never make mediocre mashed potatoes again.
The Best Potatoes for Mashing
Not all potatoes are created equal when it comes to mashing. The starch content determines the texture of your final dish.
Yukon Gold: The Winner
Yukon Golds are my top choice because they have a naturally buttery flavor and smooth texture. They are medium-starch potatoes, which means they mash up creamy without becoming gluey. They also have beautiful golden color that looks rich even before you add butter.
Russet: Classic Choice
Russets are high-starch potatoes that mash up light and fluffy. They absorb butter and cream like a sponge, making them incredibly rich. However, they can become gluey if overmixed, so handle them gently.
Red Potatoes: Not Ideal
Red potatoes and other waxy varieties hold their shape well, which is great for potato salad but not for mashing. They do not break down as smoothly and can turn gluey easily.
The Blend Approach
For the best of both worlds, I sometimes use half Yukon Golds and half russets. You get the buttery flavor and smooth texture from the Yukons plus the fluffy lightness from the russets.
The Cold Water Start Method
Here is a technique that makes a real difference: start your potatoes in cold water, not boiling. When you add potatoes to boiling water, the outside cooks faster than the inside, resulting in potatoes that are mushy on the outside and undercooked in the center.
Starting in cold water allows the potatoes to cook evenly throughout. The water and potatoes heat up together, so by the time the water boils, the potatoes are already warming through. They finish cooking gently and evenly.
How to Tell When They are Done
The potatoes are ready when a knife slides through easily with no resistance. They should not be falling apart because that means they have absorbed too much water and will be watery when mashed. Test them starting around 15 minutes after the water boils.
The Importance of Draining Well
Excess water is the enemy of creamy mashed potatoes. It dilutes the flavor and makes them soggy. After draining, return the potatoes to the hot pot and set it over low heat for 1 to 2 minutes, stirring gently. This evaporates excess moisture and concentrates the potato flavor.
You will see steam rising from the potatoes as the water evaporates. Once they look dry and slightly rough on the surface, they are ready to mash.
Warm Your Dairy
Cold butter and cream will cool down your potatoes and make them seize up. Warm them together in a small saucepan or in the microwave before adding. This helps them incorporate smoothly and keeps your potatoes hot.
How much butter and cream you use is a matter of personal preference. For restaurant-quality richness, use equal parts butter and potato by weight. That sounds like a lot, and it is, but the result is incredible. For everyday mashed potatoes, 6 tablespoons of butter and 1/2 cup of cream per 2 pounds of potatoes is a good starting point.
The Best Tools for Mashing
Ricer: The Gold Standard
A potato ricer produces the smoothest possible mashed potatoes with zero risk of becoming gluey. It presses the potatoes through small holes, creating light, fluffy strands. It is a bit more work than other methods but the results are worth it.
Food Mill: Also Excellent
A food mill works similarly to a ricer but processes larger quantities more easily. It also catches any lumps or skin, giving you a perfectly smooth result.
Masher: Good for Rustic Style
A hand masher is quick and easy and produces chunkier, rustic mashed potatoes. It is fine for everyday use but will not give you that silky smooth texture.
Electric Mixer: Use with Caution
A hand mixer on low speed can work but you risk overworking the potatoes and making them gluey. If you use one, add the butter first because fat coats the starch molecules and reduces glue formation. Then mix briefly.
Food Processor: Never
Never use a food processor for mashed potatoes. The blade cuts through the starch granules and releases so much starch that you end up with wallpaper paste. Just do not do it.
The Complete Recipe
Ingredients
- 3 pounds Yukon Gold potatoes, peeled and cut into 2-inch chunks
- 1 tablespoon kosher salt, plus more to taste
- 8 tablespoons (1 stick) unsalted butter, cut into pieces
- 1 cup heavy cream or whole milk
- Freshly ground white or black pepper
Instructions
Step 1: Cook the potatoes. Place the potatoes in a large pot and cover with cold water by 2 inches. Add 1 tablespoon of salt. Bring to a boil over high heat, then reduce to a simmer. Cook until the potatoes are tender when pierced with a knife, 15 to 20 minutes.
Step 2: Warm the dairy. While the potatoes cook, combine the butter and cream in a small saucepan over low heat. Warm until the butter melts. Keep warm.
Step 3: Drain and dry. Drain the potatoes well in a colander. Return them to the hot pot and set over low heat. Stir gently for 1 to 2 minutes until the steam stops and the potatoes look dry.
Step 4: Mash. Press the potatoes through a ricer back into the pot, or mash with a hand masher until smooth.
Step 5: Add dairy. Pour the warm butter and cream over the potatoes and fold gently until incorporated. Do not overmix or the potatoes will become gluey.
Step 6: Season. Taste and add more salt and pepper as needed. Serve immediately.
Mashed Potatoes Variations
Garlic Mashed Potatoes
Add a whole head of garlic cloves (peeled) to the pot with the potatoes. Mash them together for subtle garlic flavor. For more intense flavor, saute minced garlic in the butter before adding to the potatoes.
Loaded Mashed Potatoes
Fold in sour cream, shredded cheddar, crumbled bacon, and chives. Top with more of the same for presentation.
Boursin Mashed Potatoes
Stir in a package of Boursin cheese (garlic and herb flavor) for incredibly flavorful, company-worthy mashed potatoes.
Parmesan and Herb
Fold in freshly grated parmesan and chopped fresh herbs like chives, parsley, or rosemary.
Brown Butter
Brown the butter until the milk solids turn golden and smell nutty before adding to the potatoes. This adds incredible depth of flavor.
Common Mistakes and Fixes
Gluey Texture
This happens when you overwork the potatoes and release too much starch. Always use a ricer or mash by hand. Never use a food processor. Add butter before liquid because fat coats the starch. Work quickly and stop as soon as everything is combined.
Too Thin
You added too much liquid or did not dry the potatoes enough. Next time add the liquid gradually and stop when you reach your desired consistency.
Lumpy
The potatoes were not cooked enough or you used a masher that could not break them down. Use a ricer for guaranteed smooth results, or make sure the potatoes are very tender before draining.
Bland
Potatoes need a lot of salt. Taste and adjust until the flavor pops. Also make sure you are using enough butter and cream.
Keeping Them Warm
Mashed potatoes are best served immediately, but you can keep them warm for up to an hour. Place in a heatproof bowl set over a pot of simmering water. Stir occasionally and add a splash of cream if they start to dry out.
You can also make them ahead and reheat. Add a bit more cream and butter when reheating because they will thicken as they cool.
Frequently Asked Questions
Can I use russet potatoes?
Yes, russets make fluffy mashed potatoes but can become gluey if overmixed. Yukon Golds are more forgiving and have better flavor.
Do I need to peel the potatoes?
For smooth mashed potatoes, yes. For rustic skin-on mashed potatoes, you can leave them on but make sure to scrub well.
Can I use milk instead of cream?
Yes, but the result will be less rich. Whole milk is better than low-fat. You can also use half and half as a compromise.
How do I reheat mashed potatoes?
Add a splash of cream and reheat gently over low heat, stirring often. Or microwave in short bursts, stirring between each.
Can I make them ahead?
Yes. Make them up to 2 days ahead and store in the refrigerator. Reheat with extra butter and cream to restore creaminess.
Final Thoughts
Perfect mashed potatoes are within reach for every home cook. The keys are using the right potato, cooking them properly, drying them well, warming your dairy, and not overmixing. Follow these principles and you will produce mashed potatoes that are silky smooth, incredibly rich, and perfectly seasoned every single time.
This is the kind of dish that elevates an entire meal. Whether you are serving them alongside roast chicken, steak, or a holiday turkey, truly great mashed potatoes make everything better. They are worth the effort and the generous amount of butter.
