Kale and Roasted Vegetable Soup

This kale soup has become a regular winter staple in our home. The recipe is only slightly adapted from one that appeared in Bon Appetit magazine years ago. Vegetables are roasted, puréed, and then cooked with broth, kale, and white beans to make a wonderfully hearty soup.

Of all the leafy green vegetables, kale is my least favorite; I often find it too bitter. But in this soup, matched with the savory roasted vegetables and buttery beans, it’s fabulous!

Kale and Roasted Vegetable Soup Recipe

  • Yield: Serves 6


  • 3 medium carrots, peeled and quartered lengthwise
  • 2 large tomatoes, quartered
  • 1 large onion, cut into 8 wedges or 4 or 5 slices
  • 1/2 small butternut squash, peeled, seeded, cut lengthwise into 1/2 inch thick wedges
  • 6 garlic cloves
  • 1 Tbsp olive oil
  • 6 cups or more of vegetable broth
  • 4 cups of finely chopped kale
  • 3 large fresh thyme sprigs
  • 1 bay leaf
  • 1 15 oz can of Great Northern white beans, drained


1 Preheat oven to 400°F. 

Roast the carrots, tomatoes, onion, squash, garlic: Rub rimmed baking sheet with a thin coat of olive oil. Place carrots, squash, tomatoes, onion, and garlic on the baking sheet and sprinkle with a little more olive oil and salt and pepper. Rub the oil over all of the vegetables so that they are well coated.

Roast vegetables about 45 minutes, stirring once or twice, until they are cooked through and nicely browned.

3 Further cut the squash and carrots: Remove the roasted squash and carrots from the pan to a cutting board. Cut into 1/2-inch pieces and set aside.

4 Purée the roasted garlic, tomatoes, onions: Remove the roasted garlic from their peelings and place in a food processor. Add the roasted tomatoes and onions. Pulse in the processor until almost smooth.

5 Deglaze the roasting pan: Add a little water or broth to the baking sheet and scrape up any browned bits.

6 Start soup with browned bits, broth, puréed vegetables: Add the browned bits, the broth, and the puréed vegetables to a large pot. Add the chopped kale, thyme, and bay leaf to the pot. Heat on high to bring to a boil, lower the heat to reduce to a simmer. Simmer uncovered until the kale is tender, about 30 minutes.

7 Add roasted carrots, squash, beans: Add the roasted carrots and squash to the soup. Add the drained white beans to the soup. Simmer for 8 to 10 minutes and add more broth or water to the soup if it needs thinning.

Season with salt and pepper. Discard thyme sprigs and bay leaf.

Can be made a day ahead.

    This was amazing! The broth… so tasty! Probably the best soup I’ve every made. Every spoonful was sooooo good. I don’t care for butternut squash (it’s also a pain to cut IMO), so i subbed a couple medium yams instead. I also subbed half the kale for chard as it was what I had on hand and I used Roma tomatoes. But I made the beans from scratch :). I think you can tinker with this recipe a bit, which is nice to know. I ate this with brown rice and garlic bread (also from this site- best garlic bread ever)… so delicious! I froze some of the leftovers and they were just as tasty a week later. Vegetable soup may sound like peasant food, but the flavors are so satisfying … This is what soup was meant to be like.

    Can I substitute chicken broth for veggie? I don’t have any vegetable broth on hand.

    I plan to make this wonderful soup on a Thursday and then serve it that Saturday. Do I just leave it out, covered, for those two days, or do I refrigerate it?

    Great soup. I roasted one red bell pepper along with other veggies, and also added ground chicken browned with a roasted Anaheim chili at the very end. Very tasty and full of protein.

    Hi, Elise! Can I substitute dried thyme for the fresh? I only have dried thyme right now and would like to make this asap. If so, how much would I put in? Thanks!
