    Ingredients

    Ingredients to make truffle mashed potatoes, yukon potatoes, heavy cream, chives, butter, gruyere, truffle puree or oil.
    • Yukon gold potatoes - Yukon potatoes are great for mashing because they are buttery and fluffy when mashed.
    • Black truffle puree or truffle oil - Truffle has a robust aroma and a pungent and slightly garlicky taste.
    • Gruyere - Gruyere adds a nutty cheesiness.
    • Creme fraiche or sour cream - Creme fraiche or sour cream contribute to the richness and depth of the potatoes.
    • Whole milk or heavy cream - Whole milk or heavy cream provides extra creaminess and richness.
    • Chives - Chives add a light oniony and garlicky note.
    • Butter - Butter makes the mashed potatoes creamy and rich. We recommend using European butter like Kerry Gold because it has a higher fat content and is richer than American butter.
    • Kosher or sea salt - Kosher or sea salt accentuates the rich flavors.
    • Freshly ground black pepper - Black pepper adds a little extra spice.

    What to Serve Truffle Potatoes

    Truffle Mashed potatoes are the perfect decadent side for a holiday dinner or date night. Serve it with Turkey Au Jus and your favorite dinner dishes like Roasted Turkey, Mozzarella-Stuffed Chicken Pomodoro, or Flank Steak. They are also delicious paired with fall veggies like Honeynut Squash, Sautéed Buttered Leeks, and Roasted Shallots.

    Storage

    Store leftover truffle potatoes in an air-tight container in the refrigerator for up to 3 days. Reheat leftover potatoes in a pan or dutch oven over low heat or microwave them in a microwave safe container until warm.

    Top Tips

    • Make sure the potatoes are cut the same size before boiling them. This ensures they cook evenly.
    • Don't overcook the potatoes. Overcooking them can result in a gummy and mushy texture. Test for doneness by poking the potatoes with a fork; they should be tender but not falling apart.

    Recipes FAQs

    Yes, you can make truffle mashed potatoes up to 3 days ahead of time. Just keep them refrigerated in an air-tight container then reheat them when you are ready to enjoy.
