Begin by removing the membrane from the back of the ribs and pat them dry with a paper towel.

In a small bowl, mix garlic powder, onion powder, paprika, brown sugar, salt, and black pepper to create a dry rub.

Apply the dry rub generously over both sides of the ribs.

Place the seasoned ribs in the slow cooker, pour apple cider vinegar around them, then coat with BBQ sauce.

Cover your slow cooker and set it to low for 6 to 8 hours.

After cooking, transfer the ribs to a baking sheet and broil for 3 to 5 minutes until caramelized.

Let the ribs rest for a few minutes, then slice and serve garnished with parsley or green onions.
