Creamy Dreamy: Mashed Potatoes with Parsnip and Horseradish

There’s something so comforting about a bowl of mashed potatoes, isn’t there? I remember as a child, my grandmother used to make them every Sunday. The creamy, fluffy texture was pure bliss, and the aroma filled the entire house. I can still picture her, standing at the stove, mashing away with a determined look on her face. This recipe, while a little more sophisticated than my grandmother’s simple classic, captures that same sense of warmth and nostalgia, with a delightful kick of horseradish that wakes up the palate.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 18 minutes
• Total Time: 28 minutes
• Servings: 4-6
• Yield: About 4 cups
• Dietary Type: Vegetarian

Ingredients

• 4 russet potatoes, about 2 lb total, peeled and cut into rounds 1/4 inch thick
• 3 parsnips, about 3/4 lb total, peeled and cut into rounds 1/4 inch thick
• 4 tablespoons unsalted butter, at room temperature
• 2 tablespoons prepared white creamed horseradish
• 1 teaspoon kosher salt
• 1⁄4 teaspoon fresh ground pepper
• 1⁄3 cup warmed half-and-half, plus more as needed (or heavy cream)

Equipment Needed

• Large pot
• Steamer basket
• Potato masher
• Serving bowl

Instructions

1. Pour water to a depth of 1 inch into a large pot and bring to a boil over high heat.

2. Put the potatoes and parsnips into a steamer basket and set the basket over boiling water. (The water should not touch the bottom of the steamer basket).

3. Cover and steam until the vegetables are very tender when pierced with a small knife, about 15 minutes. To test for doneness, the knife should slide through the vegetables with little to no resistance.

4. Transfer the potatoes and parsnips to a bowl.

5. Empty the pot and wipe dry. Return the vegetables to the still hot pot. The residual heat will help to dry out the vegetables slightly, which will contribute to a fluffier final texture.

6. Add the butter, horseradish, salt and pepper.

7. Using a potato masher, mash until smooth. You can also use a potato ricer for an even smoother consistency, but I personally prefer the rustic texture achieved with a masher. Avoid using a blender or food processor, as this can lead to gluey potatoes.

8. Add the 1/3 cup half and half and mash to blend, adding more half and half, 1 Tb at a time, if needed to reach the desired consistency. Be careful not to overmix, as this can also result in gluey potatoes.

9. Transfer the vegetables to a serving bowl and serve immediately.

10. Make Ahead: This dish can be prepared up to 2 hours in advance. Cover loosely and let stand at room temperature. Just before serving, reheat gently over low heat, stirring often. Add a splash of extra half and half if needed to restore the creamy texture.

Expert Tips & Tricks

• Don’t overcook the vegetables! Overcooked potatoes and parsnips will absorb too much water, resulting in watery mashed potatoes. The key is to steam them until they are just tender.
• Use room-temperature butter. This will help it incorporate more easily into the hot potatoes and parsnips, creating a smoother, creamier texture.
• Warm the half-and-half (or heavy cream). Adding cold dairy can lower the temperature of the potatoes too quickly, affecting the overall texture.
• Taste and adjust seasonings. After mashing, give the potatoes a taste and add more salt, pepper, or horseradish as needed. Remember that flavors can mellow slightly as the dish sits.
• For an extra creamy texture, try using Yukon Gold potatoes in combination with the Russets.
• A touch of fresh thyme or rosemary can add a lovely herbal note. Stir in a teaspoon of finely chopped fresh herbs just before serving.
• Spice it up! A pinch of cayenne pepper or a dash of hot sauce can add an extra layer of warmth and complexity.
• If you don’t have a steamer basket, you can simply boil the potatoes and parsnips in a pot of water. However, steaming is the preferred method as it prevents the vegetables from becoming waterlogged. Be sure to drain the vegetables very well before mashing.
• For a vegan version, substitute the butter with a plant-based butter alternative and the half-and-half with unsweetened plant-based milk.

Serving & Storage Suggestions

Serve these mashed potatoes immediately for the best texture and flavor. They are a fantastic accompaniment to roasted meats, grilled fish, or even vegetarian dishes like lentil loaf. A sprinkle of fresh parsley or chives adds a pop of color and freshness.

To store leftovers, allow the mashed potatoes to cool completely before transferring them to an airtight container. Store in the refrigerator for up to 3 days.

To reheat, gently warm the potatoes in a saucepan over low heat, stirring frequently. Add a splash of half-and-half or milk to restore the creamy texture. You can also reheat them in the microwave, but be sure to stir them every 30 seconds to prevent them from drying out.

Freezing mashed potatoes is not generally recommended, as they can become grainy and watery upon thawing. However, if you must freeze them, use an airtight container and thaw completely in the refrigerator before reheating. Be prepared for a slightly altered texture.

Variations & Substitutions
