Ingredients
Method
- Combine onion, carrots, celery, garlic, zucchini, green beans, diced tomatoes, kidney beans, cannellini beans, broth, water, Italian seasoning, salt, pepper, bay leaf, and Parmesan rind (if using) in a 6-quart slow cooker. Stir well.
- Cover and cook on HIGH for 3 to 4 hours or LOW for 6 to 7 hours, until vegetables are tender.
- Turn slow cooker to HIGH if it isn’t already. Stir in pasta, cover, and cook 20 to 30 minutes, until pasta is just tender. Stir once halfway through.
- Remove bay leaf and Parmesan rind. Stir in spinach or kale, cover, and let sit 2 to 3 minutes until wilted.
- Taste and adjust salt. Ladle into bowls, top with Parmesan, and serve hot.
Notes
If you prefer a longer, lower cook, use the 6 to 7 hour low setting and add the pasta at the end as directed. Leftover soup thickens overnight; thin with a splash of broth when reheating. The Parmesan rind adds a rich, savory note but is completely optional.
