What is a Patty Melt?

A patty melt is a meaty, tasty that is fried to perfection with caramelized onions. The combination of the two burger patties and onions are placed between toasted bread to make a patty melt.

Patty Melt Blackstone Tips

  • Bread Type – Make sure to use rye bread, sourdough bread or artisan bread for this recipe.  White bread will fall apart if used in this recipe. 
  • Caramelizing Onions – When cooking the onions, let the onions cook slowly to enhance the flavor.
  • Cooking Meat – We recommend cooking the meat in the buttery onion flavor for enhancing the flavor.

How to Store

These patty melts are best served fresh.  If you do have leftovers, I would store the hamburger and onions separately from the bread. Place in a airtight container for up to 3 days in the refrigerator.
