Truffle Mashed Potatoes (Rich, Creamy, and Easy)

This creamy, earthy Truffle Mashed Potatoes recipe elevates a simple side dish to make it feel restaurant-worthy. It's the kind of recipe that instantly upgrades your dinner table, whether it's a busy weeknight, a holiday meal, or a special occasion.

I have to admit, my truffle obsession started with fries. I was on a truffle fries kick for months, and anytime I went out to eat, if I saw them on the menu, I had to order them. That same love of truffle oil eventually worked its way into my kitchen. 

One night, I was making my Dutch Oven Pot Roast (which I almost always finish with a drizzle of truffle oil), and I decided to try adding that same earthy richness to mashed potatoes. The result? Total game-changer. Everyone at the table was hooked, and now these truffle mashed potatoes have become a Thanksgiving staple in my house.

As a long-time nutrition coach, I love this recipe even more because it proves you don't have to give up comfort foods to eat well. Simple ingredients like potatoes, ghee, and real truffle oil make it feel indulgent, without leaning on heavily processed shortcuts.

The best part? They're quick and easy to make, but the flavor is so rich and decadent that everyone will think you spent hours in the kitchen.

Ingredients You'll Need

• Yukon Gold Potatoes: These are my go-to because they're naturally creamy, buttery, and hold up well without getting gluey. Russet potatoes work in a pinch, but Yukon Golds really give you that silky texture. When possible, I grab organic since potatoes can land on the "dirty dozen" list. Higher-quality potatoes not only taste better but also cook up with that rich, buttery flavor you want in mashed potatoes.
• Ghee or Grass-Fed Butter: I often use 4th & Heart ghee because it's lactose-free and has a nutty depth of flavor. If I'm using butter, I go with Kerrygold unsalted butter since it's grass-fed and high quality. Both give these mashed potatoes that indulgent creaminess, and using real, high-quality fats makes the flavor so much more satisfying.
• Whole Milk (or Cream): I usually use grass-fed whole milk, and if you can find raw milk, it's an incredible option because it's less processed and has a fuller, naturally rich flavor. For an ultra-luxurious mash, go with half-and-half or heavy cream. If you're dairy-free, oat milk or cashew milk blends in beautifully. The key is choosing milk with some fat-it gives you that silky, lush texture without needing tons of add-ins.
• Black Truffle Oil: I love Truff brand truffle oil because it's made with real truffle-infused olive oil, no fillers, additives, or fake "truffle flavoring." That matters for both taste and quality. Low-grade oils can taste harsh, but a good truffle oil adds that earthy, luxurious flavor that transforms plain mashed potatoes into something special.
• Sea Salt & Black Pepper: I use Redmond Real Salt for its mineral content and clean flavor, plus freshly cracked black pepper for a little heat. Potatoes love salt, so don't be shy-season as you go, taste often, and adjust until it's just right. The better the salt and pepper, the more the natural flavors of the potatoes shine.
• Fresh Chives: These add a fresh, mild onion flavor that cuts through the richness. It's a small touch, but fresh herbs really brighten up the dish and make it feel a little more elevated.

Truffle Oil 101

Truffle oil is olive oil infused with the flavor of truffles, those earthy, aromatic fungi that instantly make dishes taste restaurant-worthy.

Black vs. White Truffle Oil

For mashed potatoes, black truffle oil is my favorite-it balances beautifully with the creaminess.

• Quality Matters: Look for real truffle-infused olive oil, not "truffle flavor" or "aroma." My go-to is Truff, made with real truffle infusion and no additives.
• How to Use Truffle Oil: Use truffle oil as a finishing oil; add it after cooking to preserve its flavor. A small drizzle (about a teaspoon) goes a long way.

Substitutions And Variations

• Potatoes: Swap Yukon Golds with russet or red potatoes. Russets give you a lighter, fluffier mash, while reds create a denser texture.
• Truffle Options: If you don't have truffle oil, you can use truffle salt, truffle butter, or, if you're lucky enough to have access, fresh shaved truffles for an elevated twist.
• Add-Ins: Stir in roasted garlic for a mellow sweetness, grated parmesan or pecorino for a cheesy bite, or fresh herbs like rosemary and thyme to complement the earthy truffle notes.

Nadia's Expert Tips And Tricks

• Start with cold water: Adding your potatoes to cold, salted water ensures they cook evenly and stay fluffy. Starting with hot water can make the outside mushy before the inside cooks.
• Don't overmix: Once potatoes are mashed, stop mixing. Overworking them can make them gummy. A quick whip is all you need for creamy, cloud-like potatoes.
• Add truffle oil at the end: Heat dulls truffle oil's aroma, so always drizzle it in right before serving. A small amount goes a long way.
• Season, taste, repeat: Potatoes absorb more salt than most foods. Season early, taste as you go, and adjust until it's perfect for your palate.
• Finish with freshness: A sprinkle of chives or parsley adds brightness and color that balance the richness of the dish.

What To Serve With Truffle Mashed Potatoes

• Toppings: Finish with a drizzle of extra truffle oil, a sprinkle of flaky sea salt, or a dusting of freshly grated Parmesan cheese for a rich, savory touch. Crispy shallots or caramelized onions also add texture and depth.
• Main Dishes: Serve alongside Dutch oven pot roast, Dutch oven meatloaf, smoked whole chicken, or a perfectly seared steak or prime rib for an elegant, restaurant-quality meal. The truffle flavor pairs beautifully with rich meats and gravies.
• Seafood: These potatoes are incredible next to Traeger grilled salmon, roasted halibut, or buttery scallops. The creamy texture and earthy notes complement the delicate flavor of the fish.
• Vegetables: Round out the meal with smoked asparagus, maple roasted Brussels sprouts, or roasted carrots with feta. The freshness and slight sweetness of the veggies balance the richness of the mash.
• Holiday Pairings: Add to your Thanksgiving or Christmas table alongside Traeger smoked turkey, gravy, sourdough bread stuffing, and cranberry sauce with mandarin oranges. The truffle aroma makes the meal feel special and indulgent without extra effort.
• Family Favorites: Pair with gluten-free chicken tenders, oven-baked meatballs, or smoked boneless chicken thighs for a comforting, family-friendly dinner everyone will love.

Storage And Reheating

• Storage: Store any leftovers in an airtight glass container in the refrigerator for up to 3 days. Avoid plastic containers if possible; glass keeps the flavor and texture fresher.
• Reheating on the Stovetop: Warm the mashed potatoes over low heat, stirring often. Add a splash of milk, cream, or ghee to bring back the silky texture. Go slow and gentle; high heat can make them dry or gummy.
• Reheating in the Oven: Transfer potatoes to an oven-safe dish, cover with foil, and warm at 300°F for about 15-20 minutes, stirring halfway through. Add a drizzle of truffle oil just before serving to refresh the aroma.
