Heat the skillet at a medium temperature on a stove top for a few minutes. While the skillet is heating up, form your beef patties.
Once the skillet is heated, place your patties in the skillet and cook the patties for 6 minutes. After 6 minutes, flip the patties over and cook for 6 minutes.
In the remaining 2 minutes, add the mozzarella cheese. To ensure that the cheese on top of the patties melt, put some grease from the burger on top of the cheese.
Another option is that you can put the lid on top of the skillet.
Cooking The Mushrooms And Onions
Once the burger patties are ready, remove them from the skillet, and add the onions first. Let the onions cook for 2 minutes, then add the mushrooms.
Add the lemon pepper and red crush pepper flakes, then let the onions and mushrooms cook for 3 minutes.
Toasting The Buns
Remove the mushrooms and onions from the skillet, and replace them with the hamburger buns.
Have the flat side of the buns on the surface of the skillet, and cook the buns for 1 minute, or until desired crispiness.
Assemble The Burger
Once the bun is all nice and toasty, assemble the burger, then dig in.
