Sweet Potato & Parsnip Mash

March 26, 2011

Test Kitchen-Approved

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

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.

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.

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.
