Place the beef stew meat in the bottom of the slow cooker.
Add the chopped onion and minced garlic on top of the beef.
Add the cubed potatoes, frozen corn, barbecue sauce, beef broth, smoked paprika, salt, and black pepper.
Stir everything together until the meat and vegetables are coated with the sauce and broth.
Cover and cook on low for 8 hours or on high for 4 to 5 hours, until the beef is fork-tender.
