Place the beef stew meat, onion, carrots, celery, zucchini, diced tomatoes, beef broth, kidney beans, garlic, and Italian seasoning into the slow cooker. Stir to combine.
Cover and cook on low for 7 hours until the beef is tender.
Stir in the small pasta. Cover again and cook on high for 20 to 30 minutes until the pasta is tender.
Taste and add salt and black pepper as needed. Ladle into bowls and top with grated Parmesan cheese.
Notes
Add the pasta only at the end so it stays firm instead of turning mushy. Leftovers thicken as they sit, so stir in a splash of broth when reheating. If you want a thicker broth, mash a few beans against the side of the pot before serving.Course: Soup
