I found the best way is to line a broiler pan with tin foil, and put a grate on the top like this. I put it on the middle rack and cook at 400 flipping them once half way through. I keep it pretty simple though. I think just generously seasoning them with salt and pepper is all you need. I also like to make the patties as thin as possible at about 1/4lb a piece. So they turn out like this. I like a thick juicy burger, but they never seem to turn out right at home for me. Plus making them thin you can always double them up. The flavor always seems to turn out better that way.
