Place the vegetable broth, carrots, celery, onion, garlic, thyme, oregano, bay leaves, salt, and pepper into the slow cooker and stir to combine.
Cover and cook on low for 6 hours or on high for 3 hours until the vegetables are tender.
Add the dried pasta noodles and spinach during the final 30 minutes of cooking, stirring once to submerge the noodles.
Remove the bay leaves, stir in the fresh parsley, and serve.
Notes
Add the noodles only at the end so they stay firm instead of turning mushy. If the soup thickens after storage, stir in a splash of broth when reheating. Dried thyme and oregano work best here for steady flavor, while the parsley added at the end keeps the herb taste bright.Course: Soup
