Prepare the Dry Rub
In a small bowl, combine the smoked paprika, garlic powder, onion powder, chili powder, dried thyme, dried oregano, sea salt, black pepper, and cayenne pepper (if using). Mix well to create a flavorful dry rub.
Season the Ribs
Pat the beef back ribs dry with paper towels to ensure the rub sticks well.
Drizzle the ribs with olive oil, then generously coat them with the dry rub, massaging it into the meat on all sides. Let the ribs sit at room temperature for 20-30 minutes to allow the flavors to penetrate.
Cook the Ribs
Preheat your oven to 300°F (150°C).
Place the seasoned ribs on a baking sheet lined with aluminum foil or a wire rack for even cooking.
Cover the ribs tightly with foil to lock in moisture and bake for 2.5 to 3 hours, or until the meat is tender and easily pulls away from the bone.
Add the Finishing Touch
Remove the ribs from the oven and carefully uncover them.
Brush the ribs with your favorite sugar-free barbecue sauce or keto-friendly marinade.
Increase the oven temperature to 400°F (200°C) and return the ribs to the oven, uncovered, for 10-15 minutes to caramelize the sauce.
Serve and Enjoy
Let the ribs rest for 5-10 minutes before slicing. Serve with extra barbecue sauce on the side and your favorite keto-friendly sides, like coleslaw or cauliflower mash.
