Prepare the Dry Rub
In a mixing bowl, combine brown sugar, paprika, cumin, garlic powder, onion powder, salt, and black pepper. This blend creates a balance of sweet, smoky, and savory flavors.Season the Ribs
Pat the pork ribs dry using a paper towel. Rub the spice mixture evenly on all sides of the meat. Drying the meat helps the seasoning stick better and improves flavor absorption.Arrange in Slow Cooker
Place the seasoned ribs into the slow cooker. Pour BBQ sauce and apple cider vinegar (or apple juice) over the ribs. The liquid keeps the ribs moist and helps tenderize them during cooking.Slow Cook Until Tender
Cover and cook:👉 The ribs are done when they are fork-tender and easy to pull apart.LOW: 6–8 hours (recommended for best texture)HIGH: 3–4 hoursTransfer and Glaze
Carefully remove ribs from the slow cooker and place them on the baking tray. Brush additional BBQ sauce on top. Adding fresh sauce enhances flavor and creates a glossy finish.Broil for Caramelization
Place the tray in the oven and broil for 8–10 minutes, or until the edges start to caramelize. Watch closely to avoid burning—this step adds a rich, slightly crispy texture.Rest Before Serving
Remove ribs from the oven and let them rest for 5–10 minutes. Resting helps the juices redistribute, keeping the meat juicy.
