Ingredients
Scale
For the Patties
- 1 lb ground beef (80% lean)
- 1 tablespoon Worcestershire sauce
- Salt and pepper to taste
For the Sautéed Vegetables
- 1 tablespoon olive oil
- 1 small onion, thinly sliced
- 1 cup mushrooms, sliced (button or cremini)
For the Sandwich
- 4 slices Swiss cheese
- 8 slices rye bread
- 2 tablespoons unsalted butter, softened
- 1 tablespoon mayonnaise (optional, for extra richness)
Instructions
- Prepare the Patties: In a bowl, combine the ground beef with Worcestershire sauce, salt, and pepper. Mix gently to incorporate the seasoning but avoid overworking the meat. Form the mixture into 4 equal-sized patties and set them aside while you prepare the other ingredients.
- Sauté the Mushrooms and Onions: Heat the olive oil in a skillet over medium heat. Add the thinly sliced onions and sauté for about 5 minutes until they soften and begin to caramelize, releasing their natural sweetness. Then add the sliced mushrooms to the skillet and cook for an additional 5-7 minutes until the mushrooms release their moisture and become tender. Remove the mixture from the skillet and set aside.
- Cook the Patties: Using the same skillet, increase the heat to medium and cook the beef patties for 4-5 minutes per side, or until they reach your preferred doneness. During the last minute of cooking, place a slice of Swiss cheese on top of each patty to allow it to melt perfectly.
- Assemble the Patty Melt: Spread softened butter on one side of each rye bread slice. Optionally, spread mayonnaise on the other side of the bread for extra richness. Place a slice of bread, buttered side down, onto a clean skillet over medium heat. Add a patty with melted Swiss cheese, then a generous layer of the sautéed mushrooms and onions. Top with another slice of bread, buttered side up. Grill each sandwich for 3-4 minutes per side, pressing down gently with a spatula to ensure even crisping, until the bread is golden brown and crispy.
- Serve & Enjoy: Once the patty melt is nicely golden and the cheese is melted, remove the sandwich from the skillet. Let it rest briefly, then slice and serve immediately. This sandwich pairs wonderfully with pickles or a side of fries for a complete meal.
Notes
- Using 80% lean ground beef ensures a juicy patty while minimizing excess grease.
- Caramelizing the onions slowly brings out their natural sweetness and complements the savory beef.
- Butter the bread generously to achieve a crispy, golden crust when grilled.
- You can substitute Swiss cheese with Gruyère for a slightly nuttier flavor.
- Optional mayonnaise adds richness, but can be omitted for a lighter sandwich.
- Serve immediately for the best texture and flavor balance.
