Preheat the Oven: Preheat your oven to 140°C fan-forced.
Prepare the Ribs: Pat the ribs dry. Remove the membrane from the back if not already done.
Prepare the Spice Rub: Mix brown sugar, paprika, smoked paprika, garlic powder, onion powder, cumin, oregano, cayenne, salt, and pepper. Rub evenly over both sides of the ribs.
Protect the Ribs: Place ribs bone-side down on a large tray. Lay a sheet of baking paper on top of the ribs before covering with foil.
Slow Cook: Bake in the oven for 3.5–4 hours, checking for tenderness after 3.5 hours. The meat should pull away from the bone easily. If not, continue cooking for another 20–30 minutes.Tip: If the ribs look a little dry during cooking, baste lightly with a little olive oil before returning to the oven. Make the BBQ Sauce: Combine all BBQ sauce ingredients in a saucepan. Simmer over low heat, stirring frequently until slightly thickened, about 10–15 minutes. Taste and adjust sugar or seasoning if needed.Tip: If you’re in a rush or prefer convenience, a good-quality store-bought sauce works perfectly. High Heat Finish: Oven: Increase oven to 220°C (200°C fan-forced). Brush ribs with BBQ sauce and bake 15–20 minutes, uncovered, basting halfway through, until caramelised and sticky.
Optional BBQ/Grill Finish: Preheat the grill. Brush ribs with BBQ sauce and cook over medium heat 5–10 minutes, turning once, until caramelised and lightly charred.
Rest & Serve: Let ribs rest 5 minutes before slicing. Serve with extra BBQ sauce and your choice of sides such as corn, potato salad, or a crisp fresh salad.
