Add the vegetable broth, white beans, diced tomatoes, carrots, celery, onion, garlic, zucchini, and Italian seasoning to the slow cooker. Stir to combine.
Cover and cook on low for 6 hours or on high for 3 hours until the vegetables are tender.
Stir in the small pasta. Cover and cook on high for 20 to 25 minutes until the pasta is cooked through.
Add the fresh spinach and stir until it wilts. Season with salt and black pepper to taste.
Ladle into bowls and top with chopped fresh parsley before serving.
Notes
Add the pasta toward the end of cooking so it keeps a slight bite instead of turning soft. If you prefer a thicker soup, mash a few white beans against the side of the pot before adding the spinach. Leftovers reheat well on the stove with a splash of broth to loosen the texture.Course: Soup
