Total Time 35 minutes
Servings 2


  • 1lb 85/15 ground beef 
  • 2 small sweet onions thinly sliced 
  • 4 slices of sourdough bread 
  • 8 thin slices of gruyere cheese
  • 2 tbsp mayo 
  • ½ diced jalapeño pepper 


  • Let’s start off by prepping the veggies first.  Remove the outer skin of the onion, now thinly slice it, and set it in a bowl.
  • Now the jalapeño! Remove the stem, slice it in half, and dice with the vein and seeds. Then, set aside. In a separate bowl add 1lb ground beef, add your favorite seasoning and combine really well, now make 4 equal size meatballs, about 4 oz each. 
  • Now, preheat the loco griddle at 325 degrees and add 1 tbsp cooking oil and 1 tbsp butter. Add your onions and season them with salt and pepper. Once they are nice and translucent, set the burner on low heat.
  • On a separate section of the griddle, set it to sear mode. Then, set the meatballs on that side and use 2 spatulas to smash the Pattys. You want to flip the Pattys once the top of them are looking a bit watery.  Flip them and sear for an additional minute, (do flip the onions occasionally so they won’t burn).
  •  Flip them and sear for an additional minute, flip the onions occasionally so they won’t burn).
  • Now set the patty melts on the griddle at 350 degrees along with butter. Flip them every 2 minutes until the bread has become nice and golden brown. 
  • Let cool for 3 minutes before serving. 


You can use any sliced cheese of your choice.
