The Mushroom Swiss Burger (or Mushroom Double Swiss) is the perfect gourmet burger for the grill or cooking inside in a skillet. The juicy homemade patty is cooked gently and then topped with delicious mushrooms in a silky sauce and topped with plenty of swiss cheese. A bit different, but oh so good! Plus this is easy to make and will please the whole family.
Divide the ground beef into 4 equal balls and then shape each ball into a burger patty, use your fingers to push the center of each burger down to create a dip. (see note 2)1lb/450g ground beef/beef mince
If cooking on a grill, preheat your grill.

Transfer the burgers to your buns (with lettuce and mayo if you like)4 burger buns
Divide the mushroom mixture up between the burgers and top each with a second slice of swiss cheese.4 slices swiss cheese
I like to use button mushrooms or baby bella mushrooms for the burger. The small size means, when cooked, they stay inside the burger well, so each bite has plenty of mushroom in it. But you can use any mushrooms that you enjoy.
Creating a dent on the surface of the patty means that your burgers won't dome up when you cook them. Don't squash the burgers too hard; the lighter your touch, the softer and juicier the finished burger will be.
