Ingredients
• 42 ounces / 1.25 L vegetable broth
• 1 15-ounce can / 425 g (15 oz) tomato puree
• 1 15-ounce can / 425 g (15 oz) small white beans or Great Northern beans, rinsed and drained
• 1/2 cup / 100 g (3.5 oz) uncooked converted or long-grain white rice
• 1/2 cup / 75 g (2.65 oz) finely chopped onion
• 2 cloves garlic, minced
• 1 teaspoon (5 ml / 0.2 fl oz) dried basil
• 1/4 teaspoon (20 ml / 0.7 fl oz) salt, or to taste
• 1/4 teaspoon (20 ml / 0.7 fl oz) ground black pepper
• 8 cups / 12 ounces / 340 g (12 oz) coarsely chopped fresh kale leaves
• Vegan Parmesan cheese, for serving (optional)
Instructions
1. In a 3.5- to 4-quart slow cooker, combine the vegetable broth, tomato puree, rinsed and drained beans, uncooked rice, chopped onion, minced garlic, dried basil, salt, and pepper. Stir everything together to ensure it’s well mixed.
2. Cover the slow cooker and cook on the low-heat setting for 5 to 7 hours or on the high-heat setting for 2.5 to 3.5 hours, until the rice is tender.
3. Just before serving, stir the chopped kale into the hot soup. The residual heat will wilt the kale perfectly in just a few minutes, keeping it vibrant and tender-crisp. Ladle into bowls and, if desired, sprinkle each serving with vegan Parmesan cheese.

Pro Tips
• Brighten It Up: A squeeze of fresh lemon juice stirred in at the very end will brighten all the flavors and cut through the richness of the soup.
• Smart Storage: This soup is fantastic for meal prep. Store leftovers in an airtight container in the refrigerator for up to 4 days. It also freezes beautifully for up to 3 months.
• Green Swaps: If you’re not a fan of kale, you can easily substitute it with fresh spinach or Swiss chard. Add them at the very end, as they will wilt much faster than kale.
• Boost the Umami: For a deeper, richer flavor, add a tablespoon of nutritional yeast along with the other seasonings at the beginning of the cooking process.
FAQ
Q: Is this vegan white bean soup a good source of protein
A: Yes, this soup is an excellent source of plant-based protein. The white beans provide approximately 10 grams (0.35 oz / 9.9 g) of protein per serving, making it a hearty and satisfying meal that will keep you full and energized.
Q: Can I use different beans or grains in this vegetarian soup
A: Absolutely! This recipe is very flexible. You can easily substitute the white beans with chickpeas or cannellini beans. Instead of white rice, try using quinoa or barley for a different texture and added nutrients, though you may need to adjust cooking times slightly.
Q: How should I store this slow cooker kale soup
A: This soup is perfect for meal prep. Store leftovers in an airtight container in the refrigerator for up to 4 days. For longer storage, freeze it in individual portions for up to 3 months. When reheating, you may want to add a splash of vegetable broth as the rice will have absorbed more liquid.
Q: What other vegetables can I add to this meatless soup
A: To boost the vegetable content, feel free to add 1 cup (240 ml) of chopped carrots and celery along with the onion at the beginning of the cooking process. Diced sweet potato or butternut squash are also delicious additions for a heartier vegetarian meal.
