Bringing you a hearty vegetable soup recipe today and I couldn’t be happier!
There’s definitely nothing fancy here. Not even close.
I’d even go ahead and say this one is pretty rustic.
Who says something has to be fancy to taste good?
Certainly not me!
Once you give this celery root soup a try, you’ll be hooked. Promise.
Ingredients for Celery Root Soup
- Celery root (of course), plus other root veggies, like potato, carrot, and leek
- Veggie broth
- Salt, pepper, and thyme
- Olive oil
- Cashews & nutritional yeast (or your favourite dairy, if you want)
What Is Celery Root?
Celery root or celeriac is a hearty root veggie that’s almost like a cross between turnip and parsnip/celery.
Though the name has “root” in it, it’s definitely not the root of celery. Nope, it’s something entirely unique on its own and deserves to shine!
You can find it along other root veggies, like beets, turnips, parsnips, and so forth right in your local grocery store or farmers’ market.
Friends, please don’t judge this veggie by how it looks.
This ain’t the prettiest veggie in the world.
One may say kinda ugly.
What this bad boy lacks in appearance, it makes up for in the flavour department. It’s also quite versatile! Celery root is lovely in soups and stews, mashed, pureed, and roasted.
The exterior and interior looks somewhat like a turnip, but it has a lot of celery/parsnip vibes in the smell and taste.
To prepare, you clean up, cut off the knobby bits, peel, and carefully cut into chunks. Basically, prepare it like you would a turnip or some beets.
You should definitely consider adding this veggie to your menu soon and, if ya do, I’d love to hear how you enjoy it!
I couldn’t stop smelling my hands after I had cut into in. I know, I’m an odd one.
Replace dairy in this creamy veggie soup with cashew cream. It’s seriously amazing how some cashews can turn into a creamy dairy free (but dairy-like) replacement!
Tip: Want creamy vegetable soup without using cashew cream? No worries! Simply stir in a little half-and-half or heavy cream instead.
And, don’t worry. This isn’t going to taste overly nutty. Cashew cream has a pretty neutral flavour.
How To Make This Root Vegetable Soup
Full details are in the recipe card below, but here are the basics:
- In a large pot, heat olive oil and cook leek, carrot, and garlic.
- Add celery root, potatoes, salt, pepper, and thyme. Stir. Pour in veggie broth.
- Bring to a boil, then reduce to a simmer, cover, and cook until veggies have softened.
- Remove a couple of cups of soup from the pot, place in a heat-safe dish, blend the removed soup (with an immersion blender), and add back to the pot.
- Add cashew cream to the pot, stirring in.
- Now the delicious celery root soup is ready! Time to serve and enjoy!
Can I Blend the Whole Batch?
I happen to enjoy the texture of leaving some veggies chunky, but you do what makes your belly happy!
Soup Topping Ideas
- Homemade croutons
- Chopped fresh thyme leaves
- Shredded cheese or dollop of goat cheese
- Sliced green onion or chives
- Drizzle of cream or yogurt
- Crushed crackers
Tips and Variations
- Want even more celery root flavour? Replace the potato with more celery root!
- If you have more or less of a particular veggie, no worries! Use what you have on hand.
- Don’t have leek? Use white or yellow onion instead.
- Nutritional yeast is used in the cashew cream. It thickens a little and and adds somewhat of a slight cheesy flavour. Prefer to omit? That’s okay! And, if you use dairy (as mentioned below), omit.
- If you’d rather not use cashew cream, that’s fine. You can swirl in about ½ cup or so of half-and-half or heavy cream at the end of cook time instead.

Celery Root Soup
- 2 tablespoons olive oil
- 1 small leek, cut in half lengthwise and sliced thinly into half moons (white, light green and tender darker green parts only, not the tougher dark green part), about 1.5 cups. Rinse well and drain before using as leek can contain debris/dirt between the layers.
- 1 large carrot, peeled and cut small (about 1 cup)

- 1 pound potatoes (white or yellow), peeled and cut into small cubes (about 3 cups)

- Place cashews in a small pot with about 2 cups of water and bring to a simmer. Reduce to a low-medium simmer and cook for 15 to 20 minutes to soften cashews. Drain and rinse.
- Place cashews, nutritional yeast, and broth in a high-powered blender.
- Cover and blend until smooth and not grainy. Time may vary depending on how powerful your blender is. I don't add any salt, but you could if you prefer. Set aside.Note: If you want things thicker, use less broth.
Celery Root Soup
- Heat olive oil in a large pot or Dutch oven over medium heat. Then add leek, carrot, and garlic. Cook, stirring often, for about 5 minutes.

- Remove two cups of soup, place into a heat-safe container, and carefully blend with an immersion blender until smooth. Stir back into the soup.
