Equipment

  • cast iron skillet with a lid

Ingredients

  • 2 slices sourdough bread preferably from a bakery
  • 2 slices sharp cheddar cheese I use Adam's Reserve from Costco
  • 3 slices gruyere cheese thinly sliced
  • 2 slices Dubliner cheddar
  • 1 Tablespoon real mayonnaise I use Hellman's; more as needed
  • 1 Tablespoon freshly grated parmesan cheese no green can please

Instructions

  • Heat a 10" seasoned cast iron skillet over medium heat until the sides are hot to the touch but the pan shouldn't be smoking. (For tips on seasoning cast iron, be sure to check out my Cast Iron 101 post.)
  • Stack two slices of bread on each other so that they match in shape (like they are when you pull them out of the package.
  • Lay the bread slices stacked on a cutting board and slather the top slice facing you generously with half of the mayo. You might need more depending on your bread size.
  • Sprinkle on a good amount of fresh grated parmesan.
  • Remove the cheese and mayo coated top slice and set it aside. 
  • Layer cheese on the bottom slice in the following order: NY cheddar, gruyere, Dubliner.
  • Flip the whole sandwich over into the preheated pan. Quickly slather over mayo and a sprinkling of parm. Cover the pan.
  • Wait a painful 5 minutes before flipping (make sure the bottom is golden brown and the cheese is starting to melt. Turn over, cooking for 3-5 minutes more while keeping the lid on the pan.
  • Cut and make sure to photograph that big ole cheese pull!

Notes

All measurements are relative to the size of your bread. This recipe is more of a technique and guide than exact ingredient amounts. You might need more or less. Have fun experimenting! It's just grilled cheese!
Cheese substitutions. If you want to use different cheeses, go ahead and experiment. Just make sure to have one melty cheese (like the gruyere) in the mix. Good suggestions are Monterey Jack and fontina.
No cast iron skillet? That's ok. Just use a non-stick with a tight fitting lid or use the bottom of a pot sitting on the skillet.
