How to Cook a Roast on a Gas Grill
- 1). Select and purchase a beef roast at the local grocery store or butcher. The Betty Crocker website explains that a quality roast should be tightly wrapped and have a dark red or purplish color. Once the roast is purchased, it should be kept in the refrigerator or freezer until it is prepared for cooking.
- 2). Locate and purchase a gas grill if necessary. A regular-sized gas grill will work well for cooking a beef roast. Check to make sure that there is enough propane gas in the tank before beginning the cooking process.
- 3). Complete research online or go to the local grocery store to learn about which type of marinade should be used to best flavor the beef roast. You can use premade marinades or make your own. Marinades usually consist of a combination of spices, oils and sauces.
- 4). Wash the beef roast and place it in a deep casserole dish. Pour the marinade into the casserole dish and use a brush to cover the roast with the marinade. Occasionally rotate the meat and allow it to sit in the marinade in the refrigerator overnight.
- 5). Preheat the gas grill to 300 degrees F and allow it to warm adequately. Cover the roast with a beef rub while the gas grill is warming up. Use a grill brush to apply a layer of vegetable oil on the grill rack to prevent the roast from sticking.
- 6). Place the roast in the gas grill and rotate it after one hour. The Grilling Companion website explains that after two hours, the roast should be wrapped in aluminum foil and cooked for an additional hour. Turn the grill off and let the wrapped roast sit in the gas grill for an additional 30 minutes.
- 7). Use a meat thermometer to make sure that the roast is at least 140 to 150 degrees F internally. Remove the roast from the gas grill and carve the meat before serving it.
