my husband just got a nice big weber gas grill with 3 burners. i'm elated since i love grilled foods but i'm having a rough time with foods sticking to the grill. i follow instructions on recipes but yet the food sticks. i'm also finding that the chicken isn't fully cooked yet, the outside burns.
tonight i made grilled skinless boneless chicken thighs. easy peasy, right? not for me as half of the chicken ended up sticking to the grill. this is how i'm going about grilling. i turn on the gas; wipe the grill with oil (i dip half an onion into olive oil and use that to spread the oil onto the grill); let it preheat to 500; put chicken on; close lid; wait 4-5 minutes; flip the chicken over( or whatever i can flip that isn't sticking) then wait another 5 minutes. what am i doing wrong? should i be oiling the grill after i preheat it?
