Root Vegetable Soup
There’s nothing like Fall soups to help ease the transition from summer. Root vegetable soup – loaded with squash, sweet potato, turnip, celeriac, carrots, barley and onions – is the perfect segue into Fall.
Nutrient-rich, low calorie and, most importantly, absolutely delicious.
My friend Jane inspired me to create this root vegetable soup. She served a version of it the other night, made from a recipe she clipped out of the newspaper (no author) and it was delicious. I’m embarrassed to say both my husband and I asked for seconds, knowing there was a full dinner ahead of us.
As with many vegetarian soup recipes like this, the basics are pretty much the same.
- Sauté onions and garlic,
- Add the root vegetables you like
- Add broth (or water) and seasonings
- Simmer and serve.
The variations come from the vegetables you choose and the seasonings you add. Check out our ‘tailor to your taste’ section below to create a hearty soup you’ll love.
And I mean LOVE. I ate this soup 5 days in a row and could happily keep going!
Even with a water base, this healthy soup is so incredibly flavorful. The vegetables are surprisingly sweet in a good way. The pearl barley adds both both nutritional value (fiber, protein) and body. It thickens the soup when it sits around on the stove or in the fridge or freezer. I’m a fan of thicker soups, but if you’re not, just add more broth or water.
Needless to say, the root vegetables are also super healthy, loaded with vitamin A, K and C, antioxidants and beta-carotene. Healthy is good, but to be honest, it’s the comfort taste and texture that grab me. So good. I think I like it on day 2, 3 and 4 even better.
Tailor To Your Taste
- Vegetables: I like to use a variety of root vegetables to enhance the flavor. Pick 3-4 you like such as sweet potatoes or white potatoes, carrots, celeriac (celery root), white or yellow turnips, onions, parsnips, rutabaga or fennel (if you like the licorice taste). I also love adding butternut squash and spinach even though they are not root vegetables.
- Broth: Use vegetable broth or chicken broth or water in any combination. Homemade broth is even better if you have some.
- Herbs: I love fresh dill with this soup, but if you’re not a fan, try parsley, chives, bay leaves, chervil, thyme or sage. Even cilantro if that’s your thing. Here’s a little 101 on herbs: the bare essentials.
- Spice: Feel free to add some heat with red pepper flakes.
- Creamy or chunky texture: For a creamy root vegetable soup, you can puree the soup once it’s cooked with an immersion blender. If it’s too thick, add a bit more broth. Or, puree half the soup and leave the rest chunky. I prefer a chunky root vegetable soup, so I just leave it as is.
- Garnish options: Serve your root vegetable soup with homemade croutons (recipe included), warm crusty bread, a squeeze of lemon, a drizzle of good olive oil or some fresh grated Parmesan cheese.
How to make this hearty vegetable soup
Shortcuts
- Buy squash already peeled and cut into cubes.
- Process onions and other vegetables in your food processor instead of cutting by hand. Use a few quick pulses. You will have to do this in several batches. You may need to cut some stray pieces with a knife if they don’t get chopped as well. This shortcut can save a few minutes, but for this soup, only use the processor if you don’t mind some of the vegetables disintegrating in the soup and not left chunky.
- Use minced garlic in the jar or in frozen cubes instead of fresh garlic.
- Buy pre-washed baby spinach.
Make Ahead
- The soup can be stored in the fridge in a sealed container for 4 days. Or frozen for up to 4 months. It gets thicker on standing or freezing, so add some additional broth or water when reheating.

Recipe Notes
- Root Vegetables and quantities: To get 10-12 cups of diced vegetables, I used 1 large sweet potato (~3 cups), 2 medium-large carrots (~2 cups), 1 large celery root (~2 cups), 1 large white turnip (~2 cups) plus 2 cups cubes of butternut squash (not actually a root vegetable but great in this soup). Feel free to use any combination of these or other root veggies you like including parsnips, rutabaga and white potato.
- Broth or Water options: Use any combination of water and vegetable broth. You can even use chicken broth. I use part vegetable broth and part concentrated undiluted canned chicken broth (adding my own water) if I’m not serving to vegetarians. I find it has more depth. Needless to say, homemade vegetable or chicken broth is even better.
- Barley – soak or not? Pearl barley, the kind of barley sold in most grocery stores, has its outer husk removed, so technically there is no need to soak it. To make it cook faster, I do give it a quick rinse and soak while I’m cutting up the vegetables. Feel free to ignore.
- Homemade Croutons (for 2-4): Cut 2 slices bread into 1/2-1 inch pieces. Most breads will work. Stale is good but not essential. Heat a tablespoon of oil in a pan to medium. Add bread cubes in a single layer in pan. Sprinkle with salt (and garlic powder if desired). Continue to toast, stirring occasionally until nicely browned, about 4-5 minutes.
- Make Ahead: Root vegetable soup can be stored in the fridge in a sealed container for 4 days. Or frozen for up to 4 months. It gets thicker on standing or freezing, so add some additional broth or water when reheating.
I made the soup today in my Ninja Foodie Pressure cooker. It came out great, yes even my husband wanted a second bowl. I used onions, butternut squash, carrots, celery, turnip, parsnips, sweet potato, yukon gold potato, rutabaga, and spinach at the end. also used fresh parsley. After doing all with the onions, garlic and add the veggies and broth, 12 min on high, and quick release, everything was done perfectly. Thank you so much for the recipe.
Thanks so much for posting an instant pot/pressure cooker/Ninja version Pauline! So helpful to our readers. I really appreciate it. And glad it turned out so well. Looks like you used every root vegetable in the book! Feel free to rate the recipe, too, to help guide readers 🙂
Thank you, will give it shot and get back to you.
👍👍
can you make this in a ninja foodie pressure cooker.
Hi Pauline. I haven’t tried it so I can’t give you instructions. The closest thing I found this recipe of you want to try it https://www.eatingwell.com/recipe/276957/instant-pot-chicken-soup-with-root-vegetables-barley/. You can leave out the chicken and use vegetable broth with a bouillon cube if you like. Hope that helps.
This looks delicious and I love soup year round lol. I was wondering if I could use pot barley as it’s what I have. I’m guessing I’d need to soak it first?
Thank you Robyn
Hi Robyn, the pot barley would probably be best soaked over night in cold water (you might be able to get away with soaking for several hours). Alternatively, you can just cook it longer until tender, but the vegetables may get too soft that way. Hope that helps.
Delicious! I made it without the barley (didn’t have any on hand) and so yummy!
Good adaptation. Didn’t think of that one! Glad you enjoyed it Ginger.
Best to soak the barley ahead of time beforevadding it to the soup. I did for a few minutes but more time was needed. My veggies were over-cooked before the barley was done. The soup tasted great and next time I will soak the barley.
Hi Julie. You shouldn’t have to soak barley before adding it to the soup if you use pearl barley. But you certainly can if you want to shorten the cooking time to keep your vegetables less soft. Glad you still liked the soup.
Second time making the root vegetable soup since we enjoyed it so much the first time. A favourite for us!
Glad you like the recipe Karyn! Thanks for sharing.
