Ingredients
Method
- Place the beef and chopped onion in a 6-quart slow cooker and season with the salt and black pepper.
- Add the pinto beans, barbecue sauce and diced tomatoes with their juices.
- Stir until the beef is coated and no dense pocket of sauce sits against the crock.
- Cover and cook on low for 7 hours, until the beef is about 195°F, fork-tender and the sauce is dark and thick.
- Rest the beans uncovered for 10 minutes, then stir before serving.
