Step 1: Set up your grill for indirect grilling and preheat to medium. Brush and oil the grill grate. Arrange the sausages on the grate over the drip pay away from the heat. Indirect grill the brats until crusty and golden brown on the outside and cooked through, 30 to 40 minutes. Use an instant-read meat thermometer to check for doneness — insert it in one end to the center of the sausage— it should read 160 degrees F. There is no need to turn the sausages—remember, you’re indirect grilling.
