Notes

  • Do not overcook burgers: Make sure not to overcook your burgers, so just about 6-8 minutes per side.
  • Cheesy Mushroom Swiss Cheeseburgers: One slice of Swiss cheese is enough but if you want a cheesy burger, you should probably use at least 2, if not 3 slices.
  • Burger Toppings: Top your burger bun with your favorite toppings. Arugula, lettuce, and tomatoes are always favorites.
  • Lean Burgers: We used 80/20 ground beef but if you want a leaner burger, you can use 90/10 ground beef.
  • Burger Bun: If brioche buns are unavailable, any bun will work. 
  • Pan-Fried Burgers: You can pan-fry the burger patties if preferred.
