Ingredients

  • 2 tablespoons olive oil
  • 1 large onion, finely chopped
  • 3 cloves garlic, minced
  • 3 medium carrots, peeled and diced
  • 2 celery stalks, diced
  • 1 medium zucchini, diced
  • 1 cup green beans, trimmed and cut into 1-inch pieces
  • 1 cup diced potatoes (Yukon Gold preferred)
  • 1 (14.5 oz) can diced tomatoes with juice
  • 6 cups low-sodium vegetable broth
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 bay leaf
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons freshly chopped parsley
  • 1 tablespoon fresh lemon juice

Equipment

  • Large heavy-bottom pot or Dutch oven
  • Wooden spoon or heatproof spatula
  • Chef’s knife
  • Cutting board
  • Measuring cups and spoons
  • Ladle for serving
  • Optional: Immersion blender (for creamier texture)

Instructions

  1. Heat the olive oil in your large pot over medium heat until shimmering.
  2. Add the chopped onion, carrots, and celery. Sauté, stirring occasionally, until the onions are translucent and the carrots start to soften, about 5-7 minutes.
  3. Stir in the minced garlic and cook for another 1-2 minutes until fragrant, being careful not to let it burn.
  4. Add the diced potatoes, green beans, and zucchini to the pot. Stir to combine all the vegetables evenly.
  5. Pour in the vegetable broth and canned tomatoes with their juice. Stir well.
  6. Add the dried thyme, oregano, and bay leaf. Increase the heat and bring the soup to a boil.
  7. Once boiling, reduce the heat to low and let the soup simmer gently, uncovered, for about 25-30 minutes, or until the vegetables are tender but not mushy.
  8. Remove the bay leaf. Taste and season with salt and freshly ground pepper as needed.
  9. Stir in the fresh lemon juice and chopped parsley for a bright, fresh finish.
  10. Serve hot with crusty bread or your favorite side, or let cool and store in the fridge for up to 4 days.

Tips & Variations

“For a creamier soup, consider blending half of the soup with an immersion blender before adding the parsley and lemon juice.”

To make this soup your own, try these variations:

  • Add beans: White beans or chickpeas add protein and make the soup more filling.
  • Spice it up: Add a pinch of red pepper flakes or a dash of homemade chili powder for warmth and depth.
  • Use seasonal veggies: Swap in squash, kale, or sweet potatoes depending on what’s fresh and available.
  • Herb options: Fresh basil or dill can be great substitutes for parsley.
