Add the oil to a large dutch oven. Add salt and pepper to the cubed beef stew meat, then add to the dutch oven and allow the meat to sear on all sides, add in the diced onions and allow the onions to caramelize over low-heat. Add in the rest of the vegetables - carrots and red potatoes.
Pour in the barbecue sauce and beef broth and allow the mixture to simmer or medium-low-heat for 1 hour or until the vegetables are tender.
