# Ingredients:

01 - 1 lb ground beef (80/20 chuck)
02 - 4 slices rye bread
03 - 8 slices Swiss cheese

→ Flavor Foundation

04 - 2 large yellow onions, thinly sliced
05 - 2 tbsp unsalted butter
06 - 1 tbsp mayonnaise (plus more for spreading)
07 - Salt and freshly ground black pepper to taste
08 - 1 tsp Worcestershire sauce (optional)

→ Finishing Touches

09 - Olive oil (for cooking patties)

# Instructions:

01 - First things first, let's get those onions ready. Slice your yellow onions thinly, like you’re trying to impress a fancy chef. Seriously, thin slices are key for even caramelization. Heat a large skillet over medium-low heat with a tablespoon of butter. Add your onions, and here's the secret: patience. Stir them occasionally, letting them slowly soften and turn golden brown. This can take 20-30 minutes, sometimes even longer. Don't rush it; this is where the magic of the Classic Patty Melt Sandwich Recipe really happens. You'll smell that sweet aroma filling your kitchen, and honestly, it’s heavenly.
02 - While the onions are doing their slow dance, gently mix your ground beef with a generous pinch of salt, pepper, and that optional splash of Worcestershire sauce. Don't overmix; we want tender patties, not tough ones. Divide the beef into four equal portions and form them into oval-shaped patties that are slightly larger than your rye bread slices. They'll shrink a bit when cooked. I always make a little indent in the center of each patty; this helps them cook evenly and prevents them from puffing up like a dome. I learned that the hard way after some very round burgers!
03 - In a separate skillet (or wipe out the onion pan if you're a one-pan wonder like me sometimes), heat a little oil over medium-high heat. Cook your patties for about 3-4 minutes per side for medium doneness, or adjust to your preference. You want a nice sear on the outside. This is where your kitchen might get a little smoky, but oh, the smell of sizzling beef! Pull them off the heat and set aside, keeping them warm. Don't forget to wipe out any excess grease from the pan; we’ll use it again for the bread.
04 - Now for the fun part: assembly! Take your rye bread slices and spread a thin layer of mayonnaise on one side of each slice. This creates a barrier and helps achieve that golden crust. On the un-mayo'd side of two slices, place a slice of Swiss cheese. Top that with a cooked patty, then a generous spoonful of those glorious caramelized onions, and another slice of Swiss cheese. Finally, top with the remaining two slices of rye bread, mayo-side out. It's like building a delicious little tower, honestly.
05 - Melt a tablespoon of butter in a clean skillet or griddle over medium heat. Carefully place your assembled sandwiches into the hot pan. Grill for about 3-4 minutes per side, or until the bread is golden brown and crispy, and the cheese is beautifully melted and gooey. You might need to gently press down on the sandwiches with a spatula to ensure good contact with the pan and even browning. This step is crucial for that perfect diner-style crust!
06 - Once golden and glorious, carefully remove your patty melts from the pan. I usually let them rest for just a minute or two before slicing them in half diagonally. This helps the cheese settle a bit and prevents it from oozing out everywhere when you cut into it. The smell of toasted rye, sweet onions, and melted cheese is just incredible. Serve immediately with your favorite sides. Honestly, this is where all that patience pays off; pure sandwich bliss!

# Notes:

01 - Don't rush the onions! Seriously, low and slow is the only way to get that deep, sweet caramelization.
02 - Wrap individual patty melts tightly in foil or plastic wrap once cooled; reheat gently in a dry skillet for best results.
03 - If you're out of Swiss, provolone or sharp cheddar can work in a pinch, but Swiss is truly classic.
04 - Serve with crispy fries and a dill pickle spear for that authentic diner experience!
