Imagine a recipe that combines the two things we love about cold-weather cooking: the toasty, caramelized notes of roasted vegetables and a steaming vegetable broth. In this vegetarian recipe from Kathy Gunst’s new book, Soup Swap, we have found our new favorite soup of fall.

Add Roasted Vegetables to Your Soup

You can roast vegetables with the intention of making this soup or you can use whatever roast vegetables you have leftover to make this soup a part of your next-day meal plan. That’s what we love about a recipe like this — it uses kitchen economy to help make a delicious dinner for two nights (or even more) with one day of work.

Roasted Fall Vegetable Soup

Serves 6 to 8

Nutritional Info


  • 3

    medium leeks

  • 3

    medium parsnips, peeled and cut crosswise into 1/2-inch pieces

  • 3

    medium carrots, peeled and cut crosswise into 1/2-inch pieces

  • 1

    (2-pound) butternut squash, or any type of winter squash, peeled and cut into 1/2-inch cubes

  • 2

    large or 3 medium celery stalks, cut crosswise into 1/2-inch pieces

  • 1

    medium celery root, peeled and cut into 1/2-inch cubes

  • 2

    shallots, peeled and quartered

  • 8

    garlic cloves, thinly sliced

  • 1 1/2 tablespoons

    chopped fresh thyme leaves, or 2 teaspoons dried

  • 3 tablespoons

    olive oil

  • Salt

  • Freshly ground black pepper

  • 5 cups

    vegetable stock or canned low-sodium broth

  • 3/4 cup

    dry white wine


  1. Position a rack in the middle of the oven and preheat to 400°F.

  2. Trim off the dark green sections from the leeks and save for making vege­table stock. Halve the pale green and white sections lengthwise. Rinse under cold running water, pat dry, and cut crosswise into 1/2-inch pieces.

  3. In one large or two medium very shal­low roasting pan(s) or rimmed baking sheet(s), combine the leeks, parsnips, carrots, squash, celery, celery root, shallots, garlic, and thyme. Drizzle with the olive oil, season with salt and pepper, and toss to evenly coat the vegetables. You don't want to have vegetables on top of one another; you want them in a single layer.

  4. Roast the vegetables for 20 min­utes. Turn the oven temperature to 450°F and roast for another 10 minutes, or until the vegetables are a nice golden-brown, almost crispy on the edges, and almost soft when you gently test them with a fork or small, sharp knife. You don't want them soft and mushy; they will continue cooking in the soup.

  5. Meanwhile, in a large stockpot over high heat, bring the vegetable stock to a boil. Turn the heat to medium-low and gently simmer.

  6. Remove the vegetables from the oven, add the wine, and deglaze the pan, using a spatula to loosen any bits clinging to the bottom. Pour every­thing from the baking sheet into the stock. Turn the heat to low and simmer, partially covered, for 20 to 30 minutes. Taste and adjust the seasoning, adding more salt and pepper if needed.

  7. Ladle the soup into mugs or bowls and serve piping hot.
