Plus, it’s straightforward enough that even if you don’t consider yourself a kitchen pro, you’ll nail it every time.

Ingredients You’ll Need

Choosing the right ingredients really makes a difference in achieving those silky, flavorful mashed potatoes. Yukon Golds are my favorite because they’re naturally buttery and mash beautifully, but feel free to experiment with red or white potatoes if you prefer. The quality of butter and sour cream also plays a role in richness, so pick good ones!

• Yukon gold potatoes: Their thin skins and naturally creamy texture make mashing a breeze.
• Sour cream: Adds tanginess and that dreamy smooth mouthfeel; crème fraîche or creamy goat cheese work as decadent substitutes.
• Butter: Use unsalted for control, or vegan butter if you’re dairy-free – it keeps that richness intact.
• Kosher salt: Essential for seasoning during cooking and mashing to bring out flavors evenly.
• Fresh cracked pepper: Provides subtle heat and balances the creaminess.
• Granulated garlic: Gives consistent, mellow garlic notes without overpowering harshness.
• Optional roasted garlic cloves: Roasting caramelizes garlic, deepening its flavor—you can mash some in or use as garnish.
• Optional prepared horseradish: Adds an exciting zing if you want to mix things up.
• Chives: Perfect for a fresh, colorful finish.

Variations

One of the things I adore about this Best Garlic Mashed Potatoes Recipe is how easy it is to customize. I encourage you to play with the optional ingredients or swap in what you have on hand — mashed potatoes are very forgiving that way, and it’s fun to find your own favorite spin.

• Roasted Garlic Boost: I once mixed in a whole head of roasted garlic cloves for a mellow, deeply sweet garlic vibe – my family went crazy for it!
• Dairy-Free Version: Using vegan butter and plant-based sour cream lets you enjoy this with all the creaminess but no dairy – still delicious.
• Horseradish Kick: Adding a teaspoon or two of horseradish gives a surprising spicy zing that cuts through the richness beautifully.
• Herb Infusion: Mixing in fresh rosemary or thyme with the butter during mashing adds a lovely aromatic layer.

How to Make Best Garlic Mashed Potatoes Recipe

Step 1: Prep and Cook the Potatoes

Start by cutting your potatoes into halves or quarters, depending on size — the smaller the pieces, the quicker they’ll cook, which is key when you’re hungry! Place them in a large pot and cover with cold water, adding about two teaspoons of kosher salt to the water (this seasons the potatoes from the inside out). Bring to a boil over high heat, then cover and reduce to a simmer for roughly 15 minutes, or until the potatoes are fork-tender. Don’t skip saving a cup of the hot cooking water when you drain — this starchy water is gold for getting a smooth mash.

Step 2: Mash and Flavor

Once drained, return the potatoes to the pot and add your butter and sour cream. Pour in about half the reserved hot potato water and sprinkle in your salt, pepper, and granulated garlic. I use a potato masher for mashing and then “whisk” with it to get a fluffy texture — it really makes a difference to avoid gummy potatoes. If the mix seems too thick, add more potato water gradually until it reaches that perfect creamy consistency. Taste as you go — tweaking salt and pepper to your liking is key here.

Step 3: Optional Garlic and Horseradish Twists

If you’re using roasted garlic cloves, mash half of them into the potatoes for a subtle aromatic punch and save a few whole for garnish. For a little extra zip, stir in a teaspoon or more of prepared horseradish — it’s something I discovered experimenting with this recipe and loved the unexpected depth it brings.

Step 4: Serve and Garnish

Give your mashed potatoes a good stir before serving, then sprinkle with freshly cracked pepper and chopped chives. A drizzle of melted butter and some reserved roasted garlic cloves on top add a touch of elegance and extra flavor. Trust me, presentation makes all the difference when sharing this beauty at the table.

How to Serve Best Garlic Mashed Potatoes Recipe

Garnishes

I always top these mashed potatoes with fresh chopped chives for a pop of color and a mild oniony crunch. Plus, a sprinkle of fresh cracked black pepper adds a nice contrast. If I’m feeling indulgent, a drizzle of melted butter over the top makes it shine even more, and those whole roasted garlic cloves tucked in here and there are irresistible.

Side Dishes

This recipe pairs beautifully with classic comfort foods — think roast chicken with crispy skin, pan-seared steaks, or a slow-cooked pot roast. For vegetarians, it’s lovely alongside sautéed mushrooms or roasted Brussels sprouts, and it’s always a crowd-pleaser with holiday mains like turkey or glazed ham.

Creative Ways to Present

If you want to elevate this recipe for a special occasion, try piping the mashed potatoes onto plates or into decorative shapes using a large star tip — it looks stunning. You can also serve them in mini ramekins topped with a swirl of butter and a sprinkle of chives for individual servings that impress.

Make Ahead and Storage

Storing Leftovers

I usually transfer leftover mashed potatoes to an airtight container and refrigerate them promptly. To keep that creamy texture, I add a splash of milk or reserved potato water before reheating. Leftovers stay good for about 3-4 days in my experience, and still taste lovely with a little fresh seasoning added after warming.

Freezing

Freezing mashed potatoes can be tricky, but I’ve found that adding extra butter and sour cream beforehand helps maintain creaminess after thawing. I freeze mine in portions, wrapped tightly, then thaw overnight in the fridge before gently reheating. It’s a handy way to save time on busy weeks.

Reheating

When reheating, I prefer low and slow over the stovetop or in a microwave, stirring often and adding a little milk or potato water to loosen the texture. This helps the mashed potatoes stay fluffy, preventing them from becoming dry or lumpy. A quick stir and a little extra seasoning refresh them perfectly.
