Add the vegetable stock, tomato sauce, tomato soup, and water to the bottom of the slow cooker. Stir to combine.
Add the celery, carrots, onion, zucchini, beans, green beans, garlic, and seasonings.
Cook on High for 4 hours or Low for 6 hours.
In the last 30 minutes of cooking, stir in the pasta and cook on High for about 30 minutes until tender. Top with parsley and serve. Enjoy!
Notes
If making a big batch of the vegan crockpot minestrone soup, cook the pasta separately so it won't soak up the soup or become mushy. Just add the freshly cooked pasta into your bowls and ladle the reheated leftover soup into them.
You can chop the veggies, add all of the dry ingredients in a ziplock bag, and store them in the fridge the night before cooking. Then, you can just dump them in the crockpot the next day.
Add fresh spinach to your crockpot vegan minestrone soup at the same time you add the pasta! Vegan meatballs will also be yummy for this hearty soup. Or, before serving, why not give the soup some pizazz by stirring in pesto and fresh lemon juice?
