Preheat the oven to 300°F/150°C and line a baking sheet with baking paper.
Pat the ribs dry with paper towels and rub with olive oil on all sides.
Mix all the spices together and rub the mixture into the ribs.
Cover the ribs with foil or baking paper and cook in the preheated oven for about 2 to 2 ½ hours.
Remove the foil, and coat the ribs with the keto BBQ sauce. Turn the grill or broil setting on and cook an additional 20-30 minutes uncovered, until slightly charred.
