Author Notes: This is a variation on the technique Cook's Illustrated uses for making mashed sweet potatoes. I've used half sweet potatoes and half parsnips. To add some dimension I've incorporated freshly grated horseradish root. I've cooked part of the horseradish root with the vegetables to soften it's pungency plus stirred some in after cooking for added pizzazz. I find the combination to be sweet with enough of a bite to add interest, but not clear the sinuses! If you don't find it to be sweet enough, add a small amount of sweetener. Feel free to adjust the pungency to your taste with additional horseradish.hardlikearmour

Food52 Review: I'm always a fan of recipes that only dirty one dish from start to finish. The parsnips are wonderful with the sweet potatoes. The kick of horseradish adds something special to the dish and a tablespoon of maple syrup made it complete. - biffbourgeoisStephanie Bourgeois

Serves 4

  • 1 & 1/4 pounds orange-fleshed sweet potatoes
  • 1 pound parsnips
  • 1/3 cup heavy cream
  • 2 tablespoons unsalted butter
  • 1/2 teaspoon table salt
  • 1 packed tablespoon freshly grated horseradish, divided
  • additional salt and horseradish to taste
  • sugar, maple syrup, or honey if needed to sweeten
  1. Peel sweet potatoes and parsnips, and cut into 1/4-inch thick slices.
  2. Combine sweet potato and parsnip slices, cream, butter, salt, and half of the horseradish root in a 3 or 4 quart saucepan with a tight fitting lid. Heat over low heat, stirring occasionally, until vegetables have softened. This will take about 40 to 50 minutes.
  3. Remove from heat and mash with a potato masher to desired texture. Stir in half of remaining horseradish making sure to incorporate well. Taste and adjust seasoning with salt, additional horseradish, and/or sweetener if needed. Serve hot.

Made this for Thanksgiving -- it was perfect. Since we keep kosher, I subbed oil for the butter and almond milk for the cream -- still totally delicious.

If you are not fond of the "bite" of horseradish, you can saute the horseradish in a bit of butter -- this gives it a nice, soft, nutty flavor -- and add it when you are mashing the parsnips and potatoes. (I frequently prepare just parsnips this way it is one of my family's favorite vegetable dishes.)

Be sure to purchase the orange-fleshed variety of sweet potato. Our local grocery labels the orange sweet potatoes incorrectly as yams so our family Thanksgiving grocery runner purchased the white flesh variety labeled sweet potatoes instead. We attempted this recipe with the white variety and it simply did not work. It came out bland and boring.

Yikes! I'm sorry to hear that. I never use the white-fledged sweet potatoes so it didn't occur to me to specify.

Congrats on the Editors' Pick, HLA! I love sweet potatoes and parsnips but have never combined them before. Saving your recipe -- it looks and sounds so delicious.

Thanks, EmilyC! They are a great combo. I was just looking at your sweet potato with bacon and arugula recipe and thinking how amazing it sounded! Congrats yourself.

For some reason I get locked in on a veggie for a few weeks at a time, and I have been into parsnips for about three weeks now. I think I'll be making this soon.

Parsnips is one of my favorites! I'm actually working on a parsnip cake (think carrot cake) recipe currently. Hope to get it posted in the fairly near future.

This looks really wonderful! I hadn't thought of the sweet potato-parsnip-horseradish combo. It sounds perfect!

It was a case of me getting some fresh horseradish w/o having an idea of what to do with it, then looking through the fridge and pantry! It worked out well - nice combo of sweet with a little kick from the horseradish.

Cream does have a way of making things especially yummy!
