Scrape your grill grates clean with a grill brush. Clean grates will ensure that the scallops do not stick and tear during the cooking process.
Coat the grates with cooking oil applied with a paper towel.
Open the gas valve to your grill. Set the burners to "High," which is usually around 450 degrees Fahrenheit, and press the ignition switch to light the grill. Close the lid and let the grill heat up while you prepare the scallops.
Wrap the raw or thawed scallops in paper towels and pat them dry. If the paper towels become soaked, remove them and pat the seafood again with fresh ones.
Lay the scallops on a flat surface and use a kitchen brush to brush the scallops with whatever cooking oil and herbs your recipe calls for.
Use tongs to transfer the scallops to the grill once it is heated, oiled sides down. Quickly brush the other side of the scallops with more cooking oil.
Let the scallops cook on one side for two to three minutes.
Flip them with the tongs and let them finish cooking for another two to three minutes.
Remove the scallops from the gas grill. They should have visible grill marks and still be juicy on the inside.
