What You’ll Need

• 4 tablespoons extra-virgin olive oil, divided
• 1 medium yellow or white onion, chopped
• 3 carrots, peeled and chopped
• 2 celery stalks, chopped
• 2 cups chopped seasonal vegetables, such as sweet potatoes, green beans, butternut squash, potatoes, bell pepper, zucchini or yellow squash
• 1 teaspoon fine sea salt, divided, to taste
• 6 cloves garlic, pressed or minced
• ½ teaspoon curry powder
• ½ teaspoon dried thyme
• 1 large can (28 ounces) diced tomatoes
• 4 cups (32 ounces) vegetable broth
• 2 cups water
• 2 bay leaves
• ½ teaspoon red pepper flakes, reduce or omit if sensitive to spice
• Freshly ground black pepper, to taste
• 2 cups chopped kale or collard greens or chard (thick ribs removed), or spinach

• 1 tablespoon lemon juice

How to Make It

1. Cut root and seasonal vegetables into similar ~½-inch pieces; chop the onion, carrots, and celery; remove thick ribs and chop the greens; press or mince the garlic.
2. Heat 3 tablespoons olive oil in a large Dutch oven or soup pot over medium heat until shimmering.
3. Add the chopped onion, carrots, celery, and seasonal vegetables with ½ teaspoon salt; stir often and cook until the onion is translucent and vegetables begin to soften, about 6–8 minutes.
4. Stir in the minced garlic, ½ teaspoon curry powder, and ½ teaspoon dried thyme; cook, stirring, for about 1 minute.
5. Add the 28-ounce can of diced tomatoes with their juices and cook a few minutes, stirring often.
6. Pour in 4 cups vegetable broth and 2 cups water; add the remaining ½ teaspoon salt, 2 bay leaves, ½ teaspoon red pepper flakes, and freshly ground black pepper; turn heat up to bring to a boil.
7. Partially cover the pot, reduce heat to maintain a gentle simmer, and simmer for 25 minutes.

8. Uncover, add the chopped greens, and continue simmering for 5 minutes or until the greens reach your preferred tenderness.

9. Remove the pot from heat and discard the bay leaves; stir in 1 tablespoon lemon juice and the remaining 1 tablespoon olive oil, then taste and adjust salt, pepper, or red pepper flakes as needed.

Tips for Better Flavor

• Cut your veggies to similar sizes so everything cooks evenly; aim for about ½ inch cubes for root veggies.
• Patience is key—sauté onion, carrot, and celery until the onion is translucent for a tasty base. Don’t rush!
• Add garlic and curry powder just long enough to smell the fragrance (around 1 minute) so the garlic doesn’t burn.
• Fire-roasted diced tomatoes add a smoky twist, but plain canned tomatoes work beautifully too; for a hearty, tomato-forward bowl, see Stuffed Pepper Soup.
• Add delicate veggies like zucchini or spinach near the end to keep them tender but not mushy.
• Salt the soup in stages throughout cooking—you might need an extra ½ teaspoon depending on your broth’s saltiness.
• For more protein or heartiness, stir in cooked beans, lentils, or quinoa just before serving.
• If you like creamy soup textures, blend a portion until smooth then mix it back in for extra richness. Or go fully silky with Butternut Squash Soup.

Mix-Ins and Swaps

This vegetable soup recipe is built to be flexible so you can enjoy it year-round. The base is onion, carrots, and celery, which give a solid foundation. For a lighter, clear-broth variation, see Japanese Clear Soup.

Then add two cups of whatever seasonal veggies you love or have on hand. Here are some tasty options you can mix and match:

• Sweet potatoes or regular potatoes, cut into ½-inch chunks
• Butternut squash, peeled and cubed
• Green beans, trimmed and cut into 1-inch lengths
• Bell peppers, chopped (for a Tex-Mex vibe, take cues from Easy Taco Soup)
• Cauliflower, broken into small bite-sized pieces
• Zucchini or yellow squash, chopped
• Leafy greens: kale, collards, chard, or spinach

How to Store and Reheat

Refrigerator: Let the soup cool to room temperature before transferring it to an airtight container. Store it in the fridge up to 4 days and enjoy throughout the week.

Freezer: Portion the cooled soup into freezer-safe containers or zip bags. Freeze for up to 3 months. Leave extra space at the top of containers because soup expands as it freezes.

Reheating: Thaw in the fridge overnight if frozen. Warm gently on the stove over medium-low heat, adding a splash of water or broth if it thickened too much. You can microwave single portions as well. These tips also work for other soups like our Creamy Chicken and Mushroom Soup. Once reheated, don’t forget to stir in fresh lemon juice and a drizzle of olive oil to freshen up those flavors.

Make-ahead tip: You can make the soup through step 3 in advance and keep the base in the refrigerator for a day. Add the greens, lemon juice, and olive oil just before serving for the best texture and freshness.
