Creamy Turnip Soup

I know turnips are not usually at the top of anyone’s veggie wish list, but this soup changes minds fast. The turnips cook down with onions, garlic, and potatoes into something sweet, nutty, and gently peppery that feels a bit like a lighter potato soup with more personality.

You can use vegetable or chicken broth, keep it naturally dairy-free, or stir in a splash of cream at the end if that is your style. It works as a starter with crusty bread or as a simple main topped with crispy bacon, croutons, or turnip greens if you have them!

If you have been curious about turnips or just want another cozy soup that is not the usual potato or tomato, this is a great place to start.

Before You Get Started

Here are a few helpful things to know before you start cooking so your soup turns out mellow and creamy, not bitter.

• Choose smaller turnips: Look for small to medium turnips that feel firm and heavy for their size. Younger turnips are sweeter and less bitter than large, older ones.
• Peel the turnips: The skins can be tough and slightly bitter, and they can add a pink or purple tint to the soup. Trim the ends, then use a vegetable peeler to remove all the skin.
• Use both onions: A mix of yellow onion and sweet onion gives that deep, almost French onion flavor that makes the soup taste richer.
• Pick your broth: Vegetable broth keeps this fully vegetarian, but chicken broth adds extra savory flavor if you are not keeping it meat-free.
• Decide on potatoes or low carb: Russet potatoes make the soup extra silky and balance the turnip flavor. For a lower-carb version, use cauliflower or a mix of cauliflower and turnip instead.

How to Make Creamy Turnip Soup

Here is a quick overview of how to pull this creamy turnip soup together step by step.

1. Sauté the Onions

Warm the olive oil and butter in a large pot or Dutch oven over medium heat. Add the sliced yellow and sweet onions and cook, stirring occasionally, until they are very soft and starting to brown around the edges.

2. Add Garlic and Seasoning

Stir in the chopped garlic, dried thyme, salt, and pepper. Cook for another minute or two until the garlic is fragrant and coats the onions.

3. Simmer the Turnips and Potatoes

Add the peeled, chopped turnips and potato to the pot, then pour in the broth. Bring everything up to a simmer, reduce the heat, cover, and cook until the turnips and potatoes are very tender when pierced with a fork.

4. Blend Until Smooth

Carefully blend the soup with an immersion blender right in the pot, or transfer it in batches to a blender, and blend until completely smooth and creamy. Taste and adjust the salt and pepper, and if it tastes a bit sharp or bitter, balance it with a tiny drizzle of honey, maple syrup, or a splash of cream.

Slow Cooker & Instant Pot Method

If you prefer a more hands-off version, this soup works really well in both the slow cooker and the Instant Pot.

Slow cooker method

• Sauté first: Cook the onions in a skillet with the olive oil and butter until golden, then add the garlic, thyme, salt, and pepper and cook briefly.
• Load the slow cooker: Transfer the onion mixture to the slow cooker and add the chopped turnips, potatoes, and broth.
• Cook low and slow: Cook on low for 4 to 6 hours, until the turnips and potatoes are very tender.
• Blend and season: Blend the soup until smooth, then taste and adjust the seasoning and sweetness as needed.

Instant Pot method

• Sauté in the pot: Use the Sauté function to cook the onions in olive oil and butter until softened and lightly browned. Stir in the garlic, thyme, salt, and pepper.
• Add the vegetables and broth: Add the turnips, potatoes, and broth to the pot and stir.
• Pressure cook: Seal and cook on Manual or Pressure Cook for about 10 minutes, then quick release.
• Blend and finish: Blend the soup until creamy, then tweak the seasoning and add a touch of honey, maple syrup, or cream if the turnips are on the stronger side.

Recipe Tips and Tricks

Here are the best tips and pro tricks to help this Creamy Turnip Soup turn out perfectly every time.

• Adjust bitterness if needed: Every batch of turnips is a little different. If the soup tastes sharper than you like, blend in a small drizzle of honey or maple syrup, or a splash of half and half or cream to round it out.
• Make it low carb: Swap the potato for cauliflower florets if you want to keep the carbs lower. The cauliflower still gives body and helps soften the turnip flavor.
• Boost the creaminess: For an extra silky texture, stir in a bit of half and half, canned coconut milk, or a spoonful or two of cream cheese after blending.
• Play with herbs and spices: Thyme is classic, but rosemary, Italian seasoning, a pinch of curry powder, turmeric, or ginger can all change the flavor in fun ways.
• Add protein on top: Finish bowls with crispy bacon, crumbled chicken sausage, or even leftover shredded chicken to make this more of a meal.
• Leave it a little chunky: If you like some texture, only blend part of the soup and leave some turnip and potato pieces whole for a more rustic feel.

Serving Ideas

Here are some easy and delicious ways to serve this turnip soup.

• Top with crunch: Add homemade croutons, toasted breadcrumbs, or crispy chickpeas for texture.
• Add bacon and cheese: Crumble crispy bacon over each bowl and finish with goat cheese, Parmesan, or feta and some fresh chives or green onions.
• Use the greens: If your turnips come with greens, sauté them with a little olive oil, garlic, and salt, then mound them on top of the soup.
• Bring in some sweetness: Sprinkle bowls with finely diced apple or pear to highlight the natural sweetness of the turnips.
• Pair with bread or sandwiches: Serve with Easy Dinner Rolls, garlic toast, Spinach Artichoke Grilled Cheese, or a simple turkey sandwich to make it a full meal.
• Add a salad: An Easy Arugula Salad balances the richness of the soup and makes a nice lunch or dinner combo.

Storage & Reheating

Here is how to store, reheat, and enjoy your leftovers.

• Store in the fridge: Let the soup cool, then transfer it to an airtight container and refrigerate for 3 to 4 days.
• Freeze for later: Freeze in individual or family-size containers for up to 6 months. Leave a little space at the top for expansion and thaw overnight in the fridge before reheating.
• Reheat gently: Warm on the stovetop over low to medium heat, stirring occasionally, or reheat in the microwave in short bursts, adding a splash of broth or water if it seems too thick.
• Use up leftovers: Serve leftovers with new toppings, use as a side with roasted chicken or pork, or whisk in extra broth to turn a thicker batch into a lighter starter soup.
