Method
 

Prepare the Components
  1. Cook sliced onions in butter over medium-low heat for 25 minutes until translucent and golden-brown.
  2. Brown the beef in a skillet over medium-high heat until small, well-seared crumbles form; drain fat.
  3. Whisk mayonnaise and ketchup until a light-orange tangy sauce forms.
Assemble and Bake
  1. Spread sauce over the focaccia, then layer with beef, onions, and both cheeses.
  2. Bake at 425°F (220°C) for 10-12 minutes until cheese is bubbling with toasted brown spots.

Notes

Use freshly grated cheese for better melting.
Don't skip the caramelized onions, as they provide the classic patty melt sweetness.
