Before you turn away, give this easy turnip and potato soup a chance! It's super creamy, even though it has no dairy, and is made with a delicious combination of sauteed onions, garlic, turnips, potatoes, and thyme. It's one of my favorite recipes for introducing turnips to people who haven't tried them before, along with these tasty Roasted Turnips and Crispy Turnip Fries.

Turnips are often overlooked and misunderstood when it comes to vegetables. Most people have either never tried them or only experienced old school bitter, boiled turnips that were mushy and flavorless.

Today, I want all that to change. when picked and prepared correctly, turnips are actually sweet, nutty, and slightly peppery. Think about it as a flavor somewhere between a cabbage and a radish, but sweeter. They can be so delicious and is a great vegetable to add to your vegetable rotation.

Additionally, turnips are a nutritious, tasty vegetable that's easy to prepare, affordable, and full of vitamins and nutrients.  They are a root vegetable, similar to rutabagas and beets, that grows underground. You can eat both the root bulb and the greens (delicious sauteed and served on top of this turnip soup), and they can be found year round. Nutritionally speaking, turnips are packed with Vitamin A, C, and K, as well as calcium, fiber, and folate.  They are a great lower carb, more nutritious substitute for potatoes. 

The steps for making turnip soup including cooking the onions, spices, turnips, and potatoes.

What to serve with turnip soup?

There are so many different ways to serve this turnip and potato soup either as a starter, side dish, or the main dish for a meal.  

  • Complement the flavors of this creamy soup with some crispy croutons. Start by chopping some hearty bread with olive oil, dried herbs, salt, and pepper. Place them in a single layer on a baking sheet and bake at 375 degrees for 15-20 minutes until crispy. Top the soup with homemade croutons and some freshly chopped parsley, green onions, or chives.
  • Everything tastes better with cheese and bacon. Crisp up some bacon to sprinkle on top of the turnip soup along with some crumbly goat cheese and chopped chives. 
  • If you are lucky enough to find turnips with the greens attached, consider cooking them down with some bacon and serving on the top. 
  • To bring out more sweetness, some times I will top with soup with some fresh, diced apples. It adds a nice texture and also brings out the natural sweetness of the turnips.

Do I need to peel turnips for soup?

Turnip peels can be bitter and fibrous, so it is always a good idea to peel them before using them for soup. Also, since turnips can have a purple or pink skin, this will also ensure that your soup doesn't have a purple or pink hue. 

If you haven't worked with turnips before, they are easy to peel. Simply chop off the top knob where the greens were attached and the root if attached. Then use a vegetable peeler to remove the skin. It peels off easily.

How to pick turnips? How to decrease the bitterness of turnips?

This is the most important step to ensuring that your turnips and turnip soup do not taste bitter. To put it simply, smaller and younger turnips are sweeter and less bitter. Older and more mature turnips have more bitterness. Therefore you always want to look for small to medium size turnips to ensure that the turnips have a sweeter flavor.

Also when you cook turnips, it naturally removes from some of the inherent bitterness in turnips. 

Can this soup be frozen?

Turnip soup can be frozen for up to 6 months in an airtight container. To make it easy for future meals, try to freeze it in individual or family-size portions so you aren't defrosting soup you won't eat. Then defrost overnight in the fridge, in the microwave, or stovetop.

What do turnips taste like?

Turnips are a root vegetable that grows underground much like potatoes, rutabaga, or beets. They are a flavor that is slightly sweet and peppery. It's kind of like a mix of cabbage, cauliflower, and radish. Many people think of them as a low carb substitute for potatoes since the flavors are similar, but turnips have a stronger flavor. 

Additionally, to ensure the turnips have a sweeter flavor, make sure to always choose turnips that are small to medium in size. Ideally, they should be as fresh as possible since they get more bitter with age.

Can I make this in the slow cooker? Instant Pot?

This dish can easily be made in the slow cooker or Instant Pot. Make sure to start by cooking down the onions and garlic to bring out the flavor. Then add the onions to the slow cooker/Instant Pot with the turnips, potatoes, thyme, salt, pepper, and broth. Cook on low in the slow cooker for 4-6 hours until the potatoes and turnips are tender. Then blend. For the Instant Pot, cook on Manual for 10 minutes and quick release.

Recipe Ideas and Tips

  • To make this soup low carb or keto friendly, then substitute cauliflower for the potatoes. You could also make this soup with all turnips, but I like how the potato or cauliflower mellows out the flavor of the turnips.
  • For a creamier option, finish the soup with some half and half, canned coconut milk, or cream cheese.
  • Add a hint of heat to this soup by adding some red pepper flakes along with the thyme. 
  • Experiment with different herbs and spices to change up the flavors in the soup. Use Italian seasoning, rosemary, curry powder, turmeric, ginger, or any other combination of flavors you like.
  • If you want to add protein to this soup. consider adding some sauteed chicken sausage or bacon.
  • If you prefer a chunkier soup, only blend half of the soup and leave some of the potatoes and turnips whole.

Add to a blender (or use an immersion blender) to blend the soup until creamy. Taste and season with salt and pepper. If the soup tastes bitter, you can add a touch of honey or maple syrup to balance the flavor. You can also add a touch of half and half to balance this flavor if your turnips turn out to be on the bitter side.
