This hearty Slow Cooker Vegetable Soup is the perfect cozy meal for busy days.

Ingredients

Scale
  • 4 cups vegetable broth
  • 2 cups carrots, diced
  • 2 cups celery, diced
  • 1 onion, chopped
  • 3 cloves garlic, minced
  • 1 can (14.5 oz) diced tomatoes, undrained
  • 1 cup green beans, chopped
  • 1 cup corn (fresh or frozen)
  • 1 teaspoon dried thyme
  • 1 teaspoon dried basil
  • Salt and pepper, to taste
  • 2 cups kale or spinach, chopped
  • 1 tablespoon lemon juice

Instructions

  1. In a slow cooker, combine the vegetable broth, carrots, celery, onion, garlic, diced tomatoes (with their juices), green beans, corn, thyme, basil, salt, and pepper.
  2. Stir everything together until the vegetables and seasonings are evenly distributed in the broth.
  3. Cover and cook on LOW for 6–8 hours or on HIGH for 3–4 hours, until the vegetables are very tender and flavorful.
  4. About 30 minutes before serving, stir in the chopped kale or spinach and the lemon juice.
  5. Cover and continue cooking for the remaining 30 minutes, just until the greens are wilted and tender.
  6. Taste and adjust seasoning with additional salt, pepper, or lemon juice as needed before serving.

Notes

  • Use a low-sodium vegetable broth if you prefer more control over the salt level.
  • Frozen vegetables can replace fresh ones in equal amounts; no need to thaw first.
  • The soup thickens as it sits. Add extra broth or water when reheating if you prefer a looser consistency.
  • Feel free to swap kale for spinach or use a mix of both, depending on what you have on hand.
  • This soup keeps well for meal prep and tastes even better the next day as the flavors meld.
