Instructions:
Season the ribs with salt and pepper on both sides.
In a small bowl, mix together the barbecue sauce, brown sugar, apple cider vinegar, Worcestershire sauce, smoked paprika, garlic powder, and onion powder.
Place the ribs in a slow cooker and pour the barbecue sauce mixture over the ribs.
Cover and cook on low for 6-8 hours or on high for 3-4 hours, or until the ribs are tender.
Once done, remove the ribs from the slow cooker and place them on a baking sheet.
Preheat the oven to broil and place the ribs in the oven for 5-10 minutes, or until the sauce is caramelized and the ribs are slightly charred.
Remove from the oven and let the ribs rest for a few minutes before serving.
Enjoy your delicious slow cooker barbequed beef ribs!
