Remove the membrane from the back of the ribs. Cut each rack in half.
Rub ribs with olive oil and season generously with BBQ rub.
Stack ribs bone-side down in the crockpot. Cover and cook on LOW for 8 hours.
Transfer ribs to a foil-lined baking sheet. Brush with BBQ sauce.
Broil for about 5-7 minutes until the sauce is caramelized. Watch carefully to avoid burning. Serve hot and enjoy!
Notes
For a chewier bite, reduce cook time slightly.
If you don’t have a broiler, sear ribs in a hot skillet or grill pan after saucing. Or you can pour the sauce over them during the last hour of cooking. It will not get caramelized but it will still be delicious!
Refrigerate leftovers up to 4 days; reheat gently to preserve tenderness.
