Ingredients and notes

This creamy and fluffy mashed turnips recipe is very simple with just a few kitchen staple ingredients:

  • Turnips, 6 medium or about 1 1/2 pounds
  • 7-9 cloves of garlic (add more or less to your taste, or leave it out if you’re not a fan)
  • White vinegar (or ACV), 1 tablespoon
  • Sugar substitute, 1 tablespoon
  • Sea salt, 1 plus 1/4 teaspoon
  • Extra-virgin olive oil, 1 tablespoon
  • Butter, 1 tablespoon
  • White pepper, 1/2 teaspoon (adjust to taste)

Turnips and garlic: choose smaller / younger turnips, as they have a blander taste than larger turnips, which tend to grow bitter and fibrous.

Vinegar and sweetener: will help remove the bitterness of the turnips.

Butter: (optionally heavy cream or sour cream) I like grass-fed European butter for the best flavor! It will make a super thick and rich turnip mash. You can also add heavy cream or sour cream to stretch it out a little, making it creamier and less thick.

Spices: I added just salt and white pepper. You can change quantities or add in any other spices you like. Rule of thumb: if it tastes good in mashed potatoes, it will taste good in mashed turnips!

How to make

If you ever made mashed potatoes, you already know how to make mashed turnips! It’s basically the same thing. You’ll just add a couple extra ingredients to make sure to remove the bitterness out of the turnips.

2. Place chopped turnips in a pot with 1 tablespoon of white vinegar, 1 tablespoon of keto sweetener (like erythritol) and 1 teaspoon of salt.

3. Fill the pot with enough water to cover the turnips. Bring it to a boil then simmer for about 15 minutes.

4. Drain the boiled turnips and transfer them to a baking pan, together with the garlic cloves.

5. Toss the turnips and garlic with one tablespoon of olive oil, and take into the oven to roast for about 35 minutes or until golden. Stir the turnips at half time to cook evenly.

6. Transfer roasted turnips and garlic to a large bowl, add the butter, white pepper and 1/4 teaspoon of salt.

Serve hot, topped with salted butter if you like prefer an extra rich flavor.
