For seasonings that complement pork roast, Betty Crocker's recipe suggests garlic powder, onion powder, salt, poultry seasoning and chili powder. Food Network's recipe suggests Kosher salt, ground pepper and ground cumin.
For the Betty Crocker recipe, combine the seasonings to make a rub for the roast. Rub the combined ingredients on all sides of the roast. The roast is placed on a grill with the fat-side up for indirect cooking. After cooking the roast, place a meat thermometer into the center of the roast to ensure the temperature is 160 degrees Fahrenheit.
After creating the rub for the Food Network recipe, sear it in a cast iron skillet in olive oil on all sides. Cook the roast in the oven at 275 degrees Fahrenheit until the internal temperature is 135 degrees Fahrenheit.
