Remove the steaks from the refrigerator about half an hour before cooking to allow them to come to room temperature.
Preheat the oven to 475 degrees Fahrenheit.
Season the sirloin strips with some salt or salt and pepper.
Place a strip of uncooked or slightly heated bacon around the edge of each sirloin tip and tie it with a cooking string.
Sprinkle the steaks with pepper and salt on both sides before cooking. Over low flame, heat up a large oven-safe skillet.
Whenever the pan is heated (about 1 minute), add some butter and stir it around the skillet to coat it. Add the sirloin to the pan when the butter is sizzling and cook for 3 minutes on each side.
Put the skillet in the oven and cook until the steaks are cooked to your liking; 5-7 minutes on each side (12 minutes overall) should provide a lovely medium-rare sirloin.
You can use a meat thermometer to check the internal temperatures. The thickest section of the meat should read around 130°F for a succulent medium-rare temperature.
Take the steaks out from the oven and place them on a clean dish. Allow for 8-10 minutes of resting time after covering with tinfoil. Cut the cooking string from the steaks and serve.
