Ingredients

  • 3 cups vegetable broth (low sodium preferred)
  • 2 medium carrots, peeled and diced
  • 2 celery stalks, diced
  • 1 large potato, peeled and cubed
  • 1 zucchini, diced
  • 1 cup green beans, trimmed and cut into 1-inch pieces
  • 1 cup canned diced tomatoes (with juice)
  • 1 small onion, finely chopped
  • 3 garlic cloves, minced
  • 1 cup frozen peas
  • 1 teaspoon dried thyme
  • 1 teaspoon dried basil
  • 1/2 teaspoon smoked paprika
  • Salt and freshly ground black pepper, to taste
  • 2 tablespoons olive oil
  • Fresh parsley, chopped (for garnish)
  • Optional: 1/2 cup cooked quinoa or brown rice for added texture

Equipment

  • Slow cooker (at least 4-quart capacity)
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • Wooden spoon or heatproof spatula
  • Serving bowls and ladle
  • Optional: Blender or immersion blender if you prefer a creamier texture

Instructions

  1. Prepare the vegetables: Wash and chop the carrots, celery, potato, zucchini, green beans, onion, and garlic as indicated in the ingredients list. This will ensure even cooking and a balanced texture in your soup.
  2. Sauté the aromatics: In a skillet, heat the olive oil over medium heat. Add the chopped onion and garlic and sauté for about 3-4 minutes until fragrant and translucent. This step intensifies the flavor but can be skipped if you’re short on time.
  3. Add all ingredients to the slow cooker: Transfer the sautéed onion and garlic to the slow cooker. Add the carrots, celery, potato, zucchini, green beans, diced tomatoes with juice, dried thyme, dried basil, smoked paprika, and vegetable broth.
  4. Season the soup: Sprinkle in salt and pepper to taste. Remember you can always adjust seasoning later once the soup is cooked.
  5. Cook low and slow: Cover the slow cooker and set it to low heat. Allow the soup to cook for 6-8 hours or until the vegetables are tender and the flavors are well combined.
  6. Add peas and optional grains: About 15 minutes before serving, stir in the frozen peas and cooked quinoa or brown rice if using. Cover and cook on high until the peas are heated through.
  7. Final taste and garnish: Taste the soup and adjust salt and pepper if needed. Ladle the soup into bowls and garnish with freshly chopped parsley for a burst of freshness.

Tips & Variations

“For a creamier version, blend half the soup with an immersion blender before adding the peas. This adds a lovely texture without the need for cream or dairy.”

You can easily tailor this veg soup to your preferences or pantry availability:

  • Swap veggies: Add mushrooms, bell peppers, sweet potatoes, or kale for different flavors and textures.
  • Boost protein: Add cooked beans such as cannellini or chickpeas during the last hour of cooking.
  • Spice it up: Add a pinch of chili flakes or a dash of hot sauce for a warming kick.
  • Use fresh herbs: Fresh thyme, basil, or rosemary can be added in the last 30 minutes for a vibrant finish.
  • Make it hearty: Toss in pasta or barley 30 minutes before the end of cooking for a more filling meal.
