Recipe Notes:

  • I used Cremini mushrooms, but shitake or button would work as well.
  • If you have a burner on your grill, you could make the mushrooms and onions outside at the same time that you are grilling your burgers.
  • Don’t like Swiss cheese? Substitute your favorite cheese.
  • I used 85/15 ground beef to make these burgers. Personally, I prefer the higher fat content because it adds more flavor, but they also shrink up as all of the fats melts.
  • I chose to make 3) one-third pound burgers instead of 4) quarter pound burgers. Make whichever quantity that you prefer.
