Horseradish
Prepared horseradish adds a sharp, peppery heat that brightens the creaminess of the potatoes. Unlike wasabi-level spice, horseradish offers a quick kick that mellows out when balanced with dairy. It’s a traditional condiment for beef dishes, but when stirred into mashed potatoes, it creates a side dish with personality.
Yukon Gold Potatoes
Yukon Golds are a favorite for mashed potatoes because of their naturally buttery flavor and creamy texture. They strike the perfect balance between waxy and starchy, which means they mash smoothly without becoming gluey. Their golden color also adds a warm, appetizing look to the dish. Here we used purple potatoes for a pop of color and they turned out beautiful, bright and delicious!

Recipe Origin / Inspiration | HORSERADISH MASHED POTATOES
I wanted to create a mashed potato recipe that wasn’t just another “creamy potato side.” Inspired by classic steakhouse flavors, this dish combines the creaminess of traditional mashed potatoes with the bold, zippy bite of horseradish and Dijon mustard. The addition of chives brings a fresh, oniony note that balances everything out.
This recipe is tailored for two people—perfect when you don’t need a giant pot of potatoes but still want a restaurant-quality side dish. It pairs especially well with rich proteins like salmon, steak, or pork, making it a versatile side you’ll want in your rotation.

Tips, Serving Suggestions, or Storage Advice
Leave the skins on for extra texture and nutrients, or peel them for a smoother mash.
Always start potatoes in cold water so they cook evenly.
Salt the water generously—it’s your only chance to season the potatoes deeply.
Don’t over-mash or they can become gummy. Use a potato masher for best results.
Warm the cream, garlic, and butter before mixing—it prevents the potatoes from seizing.
Adjust horseradish to your taste—start with less and add more if you like it spicier.
Fold in chives right before serving to keep their fresh flavor.
Serve immediately for the creamiest texture, as potatoes thicken when they sit.
Leftovers can be refrigerated in an airtight container for up to 3 days.
Reheat gently with a splash of cream or milk to restore creaminess.

Horseradish Mashed Potatoes for Two
Ingredients:
1 ½ lbs Yukon Gold potatoes (or any potatoes of your choice)
1 garlic clove, grated

2 tablespoons salted butter
4 oz sour cream
1 tablespoon prepared horseradish
1 teaspoon Dijon mustard
2 tablespoons minced chives
Kosher salt, to taste
Freshly cracked black pepper, to taste

Drain the potatoes in a colander, then return them to the hot pot.
Lightly mash the potatoes, then add the warmed cream mixture. Continue mashing, then stir in horseradish, sour cream, and Dijon mustard. Mix until the potatoes reach your desired texture.
