Ridiculously Good Patty Melt

I’m not one that’s usually drawn to “patty melts” when eating at a restaurant, but after constant nagging from my husband, I began creating our own recipe. WOW. If I had to pick one super hearty comfort food, now, this Patty Melt recipe at the top of my list. DANG it’s delicious. The sourdough bread combined with the caramelized onions and quick burger sauce will make your taste buds sing! It’s 100% restaurant worthy and couldn’t be easier to make!

How to make a Patty Melt:

Prep Toppings: Make burger sauce by mixing all the ingredients in a bowl. (Can be made up to several days ahead).

Caramelize Onions: Heat a cast iron skillet over medium heat then add butter and oil. Once melted, add onions and season with salt and pepper. Cook, stirring frequently, until golden brown and caramelized, about 20 – 25 minutes. Add a splash of water as needed, if the onions seem to be drying out. Remove to plate then set aside. (Can be made 1-2 days ahead).

Make Burger Patties: Divide meat into five patties (about 4.8 ounces each) and shape them them roughly the same shape as the bread you’re using. Handle the meat as little as possible. Season generously on both sides with salt and pepper.

Cook patties: Heat a flat-top griddle or cast iron pan over medium-high heat and grease with 1 Tablespoon oil. Add burger patties and cook for 3-4 minutes, flipping once, until medium-rare, or as desired (I like to cook them to medium rare/slightly pink inside, as they will cook more as they rest, and when added to the patty melt). Remove to plate to rest.

Assemble: Wipe pan clean and lower pan heat to medium-low. Butter one side of each piece of bread then place one buttered side of bread face down in hot pan. Top with a slice of cheese, beef patty, a spoonful of onions, drizzle of burger sauce, another slice of cheese, and top slice of bread (butter side facing up). Cook for a few minutes, until bread is toasted on the bottom. Gently flip then cook on opposite side until golden and cheese is melted.

Serve this easy patty melt with leftover burger sauce for dipping, if desired.

Make Ahead Instructions:

To Make Ahead: The sauce can be made ahead of time and kept in the fridge until ready to assemble the homemade patty melt. The caramelized onions could also be cooked 1-2 days ahead, and reheated for a few seconds before serving.
