  • 3 cloves garlic, minced
  • 2 medium potatoes, peeled and diced
  • 1 cup green beans, chopped into 1-inch pieces

  • 1 tsp dried thyme
  • 1 tsp dried basil
  • 1/2 tsp smoked paprika

Instructions

  1. Prepare the vegetables: Wash and chop carrots, celery, onion, potatoes, green beans, and kale (if using). Mince the garlic cloves.
  2. Sauté aromatics (optional): In a skillet, heat olive oil over medium heat. Add onions and garlic and sauté for 3-4 minutes until fragrant and translucent. This step deepens flavor but can be skipped if short on time.

  6. Add greens: About 30 minutes before serving, stir in the chopped kale or spinach and allow it to wilt.
  7. Adjust seasoning: Taste the soup and add more salt, pepper, or herbs if needed.
  8. Serve hot: Ladle into bowls and enjoy your wholesome slow cooker veggie soup!

Tips & Variations

“Feel free to get creative with your vegetable choices! Sweet potatoes, zucchini, bell peppers, or butternut squash all make excellent additions.”

  • Make it creamy: For a creamy version, blend a portion of the soup with an immersion blender or in batches in a countertop blender.
