Rainbow Vegetable Soup

A pot of colorful vegetable soup

There is something inherently healing about a pot of vegetable soup. For me, this Rainbow Vegetable Soup is the ultimate "reset" meal. Whenever I’ve had a few too many heavy dinners or I’m feeling a bit under the weather, I turn to this recipe. It’s packed with every color of the rainbow—red tomatoes, orange carrots, yellow corn, green beans, and purple kale. But don't let the healthy ingredients fool you; this soup is incredibly flavorful thanks to a base of sautéed aromatics and a pinch of smoked paprika. It’s a versatile dish that clears out the crisper drawer and leaves you feeling nourished and satisfied. Plus, it smells like a dream as it simmers on the stove.

Ingredients

  • 2 tbsp extra virgin olive oil: For sautéing.
  • 1 large yellow onion: Diced.
  • 3 cloves garlic: Minced.
  • 2 large carrots: Peeled and sliced into rounds.
  • 2 stalks celery: Diced.
  • 1 large red bell pepper: Diced.
  • 1 medium zucchini: Quartered and sliced.
  • 1 can (14.5 oz) diced tomatoes: With their juices.
  • 6 cups vegetable broth: Low sodium preferred.
  • 1 tsp dried thyme: For a floral, herbal note.
  • 1/2 tsp smoked paprika: For a subtle smoky depth.
  • 1 cup frozen corn: Or fresh if in season.
  • 1 cup frozen peas: Added at the very end.
  • 2 cups chopped kale or spinach: Tough stems removed.
  • Salt and black pepper: To taste.

Step-by-Step Instructions

  1. Sauté Aromatics: Heat the olive oil in a large pot or Dutch oven over medium heat. Add the onion, carrots, and celery. Sauté for 6-8 minutes until the onions are translucent and the carrots begin to soften.
  2. Add Garlic and Spices: Stir in the minced garlic, dried thyme, and smoked paprika. Cook for just 1 minute until fragrant, being careful not to burn the garlic.
  3. Incorporate Peppers and Zucchini: Add the red bell pepper and zucchini to the pot. Sauté for another 3-4 minutes.
  4. Pour in the Liquids: Add the diced tomatoes (with juices) and the vegetable broth. Stir well to combine.
  5. Simmer: Bring the soup to a boil, then reduce the heat to low. Cover and simmer gently for 20-25 minutes, allowing the flavors to develop and the vegetables to become tender.
  6. Add the "Quick" Veggies: Stir in the frozen corn and frozen peas. These only need a few minutes to heat through.
  7. Wilt the Greens: Add the chopped kale or spinach. Stir until the greens are wilted and bright green, which should take about 2-3 minutes.
  8. Season and Serve: Taste the soup and add salt and pepper as needed. Ladle into bowls and serve hot with a piece of crusty bread.

Tips

  • Don't Overcook the Greens: Add your kale or spinach at the very end. If they cook too long, they lose their vibrant color and become mushy.
  • Customize the Veggies: This is a "clean out the fridge" soup! Feel free to swap in green beans, potatoes, sweet potatoes, or even butternut squash depending on what you have on hand.
  • Add a Parmesan Rind: If you have a leftover rind from a block of Parmesan cheese, throw it in the pot while the soup simmers. It adds an incredible savory depth (umami) to the broth.

FAQ

Yes! A can of cannellini beans or a half cup of cooked quinoa or small pasta (like ditalini) makes this soup even more filling. Add them in during the last 10 minutes of simmering.

Absolutely. This soup freezes beautifully for up to 3 months. Just be sure to leave a little room at the top of your container for expansion as it freezes.

If your broth feels a bit thin, add a tablespoon of tomato paste during the sautéing step, or finish the soup with a squeeze of fresh lemon juice or a teaspoon of balsamic vinegar right before serving.
