What Are Turnips?

Turnips are a root vegetable, and they’re loaded with nutrition and some studies have even shown them to aid in blood sugar control and may contain anti-cancer properties.

You can eat the root (bulb) and leaves of the turnip, though I don’t usually see turnip greens outside the Southern states. You can cook the turnip greens much like collard greens or even kale.

What you’re most likely to find is the common white and purple turnip bulb.


How to Select and Prepare Turnips

When you’re shopping for turnips, look for hard, not wrinkly bulbs. The skin should be firm and the top of the turnip bulb, where the greens were cut, should be fresh and not discolored.

Larger is not better!

Because turnips are a root vegetable, they can be fibrous and woody. The bigger the turnip, the more likely it is to be tough and woody. I like to pick smaller fist-size turnips.

Turnips need to be peeled before cooking, but you can make short work of that with a vegetable peeler. Just trim the top (stem end) and the bottom (root end) and then give it a peel, revealing the white flesh under the skin.

Ingredients to Make Mashed Turnips

Get ready for a huge list of ingredients – I’m just kidding! There’s just a handful of ingredients in this turnip mashed potato recipe.

  • Turnips
  • Butter
  • Heavy whipping cream
  • Salt and pepper

How To Make This Mashed Turnip Recipe

  1. Cube and boil the turnip in salted water until very soft.
  2. Pop the well-drained turnips, butter, and heavy cream into a food process or get out your handy masher.
  3. Pulse (or mash) until smooth and creamy.
  4. Season with salt and pepper and serve!

Chef Jenn’s Tips to Make Mashed Turnips

These tips will help you make delish turnip mashed potatoes:

  • Drain your turnips REALLY well. The wetter they are, the soupier your mash will be.
  • If your mash is too wet, put it in a non-stick skillet or pot over medium heat and stir continuously to evaporate some of the moisture and to thicken up your mash.
  • Want more flavor? Add some chopped green onions, cheddar cheese, garlic powder, or even a pinch of crushed red pepper flakes to add some heat.

What To Serve With Mashed Turnips

Anything with a sauce or gravy will pair well with this mashed turnip recipe, or when you’ve got a big, flavorful meat and don’t want your side dish to compete.

Cajun Salmon, Mustard-Glazed Pork Loin, or even Steak Bites will all pair well with this keto side dish recipe. Or, serve it alongside this keto Shepherd’s Pie.

Are Mashed Turnips Freezer Friendly?

Yes and no. You can freeze Mashed Turnips, but they tend to be more watery after thawing. If you do freeze them, thaw them and then reheat on the stovetop in a non-stick skillet or pot over medium heat to evaporate some of the liquid.

I prefer to eat this keto vegetable recipe fresh.

Are mashed potatoes keto?

Nope, not even close because they’re way too high in carbs. But, you can mash cauliflower or turnip and get something close!

How long to boil turnips for mashing?

It really all depends on how big you cut the turnip. I cut them into 1-inch cubes and boil them for about 8 minutes. The key is to get the turnips VERY soft.

Are turnips keto?

Yes! They’re high in fiber and naturally lower in carbs, making them a great keto choice.
