Step 1: Prepare the Beef Patties
- Divide the ground beef into 4 equal portions and form each into a thin patty. Season both sides with salt and pepper. Optionally, mix a little Worcestershire sauce into the beef for added flavor.
- Heat a skillet or griddle over medium-high heat. Cook the patties for about 3-4 minutes per side or until they reach your desired level of doneness. Remove the patties from the skillet and set aside.
Step 2: Caramelize the Onions
- In the same skillet, add 1 tablespoon of butter and reduce the heat to medium-low. Add the sliced onions and a pinch of salt, and cook, stirring occasionally, until they are deeply caramelized and golden brown, about 20-25 minutes. Remove from the skillet and set aside.
Step 3: Assemble the Patty Melts
- Butter one side of each slice of rye bread. On the non-buttered side of four slices, place a slice of cheese, followed by a beef patty, a generous helping of caramelized onions, another slice of cheese, and finally, top with another slice of bread, buttered side up.
- If desired, spread a thin layer of mustard or Thousand Island dressing on the inside of the bread before assembling for extra flavor.
Step 4: Cook the Patty Melts
- Heat a clean skillet or griddle over medium heat. Place the assembled sandwiches in the skillet, pressing them down slightly with a spatula.
- Cook for about 3-4 minutes on each side, or until the bread is toasted to a golden brown and the cheese has melted. You may need to cook them in batches depending on the size of your skillet.
Step 5: Serve
- Once cooked, remove the patty melts from the skillet and let them rest for a minute before cutting. This helps the cheese set slightly and makes them easier to cut.
- Cut each patty melt in half and serve hot.
Tips:
- For an even juicier patty, consider adding a small amount of minced garlic or onion powder to the ground beef mixture.
- Ensure the onions are cooked on a low enough heat to caramelize without burning, adding a splash of water to the pan if they start to stick.
- The key to a great patty melt is the rye bread and Swiss cheese, but feel free to experiment with different types of bread and cheese to find your favorite combination.
