Mix the Low Carb Rib Rub together in a small bowl and set aside. Turn them over and slice gashes in the membrane of the back of the racks to allow the rib rub to penetrate better. Massage the entire batch of Low Carb Rib Rub into the ribs, covering the front, backs and edges. Lay on the baking sheets and bake for 4-5 hours.
Carefully take out the rack of ribs from the slow cooker (the bones will fall off easily) and place on a baking tray. Spoon half of the BBQ sauce from the slow cooker and pour over the ribs. Bake in the oven for an additional 10 minutes to get that crispy flavourful skin.
If you want to try this in the oven, rub the short ribs with the bbq seasoning and place in a baking dish. Cover with aluminum foil and bake for 3 hours in a 300 °F oven. Take off the foil for the last 1/2 hour.
Line a baking sheet with tin foil, spray with cooking oil and heat the oven to 250°. Turn the ribs over and slice gashes in the membrane of the back of the racks to allow the rub to penetrate better. Massage the entire batch of Keto Rib Rub into the ribs, covering the front, backs and edges.
