Start by removing the membrane from the back of the ribs.

In a bowl, combine the garlic powder, onion powder, smoked paprika, salt, and pepper.

Rub the seasoning mix all over the ribs, ensuring they're evenly coated.

Place the seasoned ribs in the crockpot. Cut them into smaller sections to fit if needed.

Drizzle the barbecue sauce and apple cider vinegar over the ribs.

Cover the crockpot and cook on low for 6 to 8 hours.

Check for doneness; the ribs should be falling off the bone. Cook for an additional hour if needed.

Once done, carefully remove the ribs and let them rest for a few minutes.
