Preheat the oven: preheat the oven to 180°C / 350-375°F / Gas Mark 4-5.
Baking dish: lightly spray a baking dish with olive oil. Then use kitchen tongs to place the ribs into the oiled dish.
Dry rub: add the garlic powder, onion powder, mustard powder, paprika, cayenne pepper, salt and pepper to a small glass and use a mini whisk to stir and combine.
Rub onto ribs: use your fingers to sprinkle the rub all over the ribs, rubbing it into the meat as you go. Use tongs to flip the ribs and repeat for the other side, top and bottom.
Worcestershire sauce: pour the sauce into the baking dish. Not so much over the ribs, but as a layer of liquid in the bottom of the dish.
Oven bake: cover the baking dish with tin foil and place the ribs into the preheated oven on the middle shelf. Allow them to cook for 1 hour.
BBQ sauce: use oven mits to remove the baking dish from the oven and place on a heatproof surface. Pull the tin foil off and discard. Use kitchen tongs to rotate each rib to the other side. Use a pastry brush to coat the top side of each rib with BBQ sauce. Return the baking tray to the oven and allow the ribs to bake in the oven for a further 10 minutes.
Grill/broil: use oven mits to remove the cooked ribs from the oven and place on a heatproof surface. Change the oven setting to grill at 200°C 392°F6. Use kitchen tongs to transfer each rib to a silcon baking mat on an oven rack and tray. Use the pastry brush to re coat each rib with BBQ sauce. Place the tray into the oven on the top shelf. Grill the ribs for 10 mins.
Serve and enjoy: use oven mits to remove the baking tray from the oven and place on a heat proof surface. Let the ribs rest for 1 to 2 minutes before using tongs to transfer them to a serving plate. Provide additional BBQ sauce (optional) for serving.
