For the Patty Melt Assembly:

- 3 tbsp butter (for toasting the bread)
- 2 tbsp mayonnaise (for extra crispiness, optional)
Optional Add-Ons:

Step-by-Step Instructions
Step 1: Prepare the Mushroom & Onion Topping
- In a skillet, melt butter and olive oil over medium heat.
- Add the sliced onions and cook for 3-4 minutes until they begin to soften.
- Add the sliced mushrooms, salt, and black pepper, and sauté for another 5-7 minutes until golden and caramelized.
- Stir in balsamic vinegar (if using) and cook for 1 more minute. Remove from heat and set aside.
Step 2: Make the Beef Patties
- In a mixing bowl, combine ground beef, salt, black pepper, garlic powder, onion powder, and Worcestershire sauce.
- Gently mix with your hands, then divide into 4 equal portions and shape them into oval patties (so they fit the bread better).
- Heat a large skillet or griddle over medium-high heat.
- Cook each patty for 3-4 minutes per side until browned and fully cooked. Remove from heat.
Step 3: Assemble the Patty Melt
- Spread mayonnaise or butter on one side of each bread slice.
- Lay a slice of Swiss cheese on the unbuttered side.
- Place a cooked beef patty on top of the cheese.
- Add a generous amount of mushroom and onion mixture over the patty.
- Top with another slice of Swiss cheese and close with another piece of bread (buttered side facing out).
Step 4: Toast the Patty Melt
- Heat a skillet over medium heat.
- Place the sandwiches in the skillet and cook for 2-3 minutes per side, pressing down gently with a spatula.
- Flip carefully and cook until the bread is golden brown and crispy, and the cheese is melted.
Step 5: Serve & Enjoy!
- Remove from the skillet and let rest for 1-2 minutes before slicing in half.
- Serve with fries, pickles, or a side salad for a complete meal!

Tips & Tricks for the Best Mushroom Swiss Patty Melt
???? Use a Blend of Mushrooms – Cremini, shiitake, or portobello add extra depth of flavor.
???? Choose the Right Bread – Rye bread gives an authentic taste, but sourdough or Texas toast works well too.
???? Press the Sandwich While Cooking – Use a spatula to lightly press down for even crispiness.
???? Melt the Cheese Perfectly – If the bread is browning too fast, lower the heat so the cheese melts evenly.
???? Add an Extra Sauce – Thousand Island dressing or Dijon mustard makes a delicious spread inside the sandwich.
Serving Ideas & Variations
???? Make it Bacon-Loaded – Add crispy bacon slices for extra crunch.
???? Breakfast-Style Patty Melt – Top with a fried egg for a rich, savory twist.
???? Lighten it Up – Use ground turkey instead of beef and swap rye bread for whole grain.
???? Extra Cheesy – Use a mix of Swiss and provolone for a gooier melt.
How to Store & Reheat
???? Store in Fridge – Keep leftover patty melts wrapped in foil or an airtight container for up to 3 days.
???? Reheat – Toast in a skillet over medium heat for 2-3 minutes per side to keep the bread crispy.
❄️ Freeze for Later – Assemble and freeze uncooked patty melts. When ready to eat, cook straight from frozen.
