Miso Charred Carrot Soup

September 17, 2018

Test Kitchen-Approved

Author Notes: An easy-as-heck soup to keep on repeat all fall and winter. Roast root vegetables (in this case, carrots) with celery and onion. Then blend the charred results with water and lots of mellow white miso. That’s it. Emma Laperruque

Serves: about 9 cups
Prep time: 25 min
Cook time: 1 hrs 15 min


  • 2 pounds carrots, peeled and chopped into 1-inch chunks
  • 1 pound celery, chopped into 1-inch chunks

In This Recipe


  1. Heat the oven to 425°F. Line two sheet trays with silicone mats or parchment.
  2. Add the carrots to one tray. Drizzle with 1 tablespoon oil and 1/2 teaspoon salt. Toss with your hands. Add the celery and onion to another tray. Drizzle with the remaining 2 tablespoons oil and sprinkle with 1 teaspoon salt. Toss with your hands.
  3. Stick both trays in the oven and roast for about 1 hour total. Every 20 minutes, rotate the trays and stir vegetables to encourage even cooking.
  4. When the vegetables are done remove both trays from the oven. Add about half of each tray to a blender. Add 2 tablespoons miso and 4 1/2 cups water. Blend until completely smooth, then pour into a large pot on the stove. Repeat with the remaining vegetables, remaining 2 tablespoons miso, and another 4 1/2 cups water—blended until smooth, poured into the pot.
  5. Season the soup with salt, if necessary. Thin with more water, if necessary, depending on how thick you like your soup. Warm over medium-low heat, stirring often, until it’s the temperature you like to eat your soup. Pour into a bowl and serve.

Loved the flavor, but it's hard to get everything pureed smoothly when you're intentionally burning the outside of the veggies (I used a ninja blender, which is pretty strong). Worked much better for me when I pureed the veggies with much less water to get them a bit smoother, then added the water incrementally. I'll be trying it with broccoli instead of carrots soon!

I really wanted to like this. I used my blender, then added more water once it was in the pot, because it was still pretty chunky. Then the soup was diluted. So I added more miso, then blended it even longer with my hand blender. Still way too chunky for a double blended soup. And now I have so much soup; I have soup for all of autumn. I think one needs a vitamix for this. everything about this screamed easy and delicious, but for me it was more effort than payoff.

I made & w/Vitamix it was a breeze. Definitely a keeper.

Very disappointing, but it may have been too strong miso.
Berk O. October 7, 2018
Not bad. Seeing that it has miso, therefore an Asian twist, I added some shichimi togarashi for a kick. With added salt, came together. I also reduced the water to 8 cups for a thicker soup...

I just made this. Good flavour and sooo easy! Only thing was my soup has little fibrous strands in it (celery?) Did I not blend it well enough? I only have a hand blender.

Glad you liked it, Wade! Sounds like the hand blender might not have been strong enough. If you make the recipe again, you could: 1) peel away the tougher, fibrous outer layer of the celery before chopping and/or 2) chop the celery smaller before roasting, then adjust the cook time accordingly.
