Swiss Mushroom Melt Delight

Sauté the mushrooms – Melt butter in a skillet over medium heat. Add mushrooms and cook until they release their moisture and turn golden brown. Set aside.
Prepare the beef patty – Mix ground beef with Worcestershire sauce, salt, and black pepper. Shape into patties slightly larger than the bread. Cook in a skillet over medium-high heat until browned and cooked through.
Assemble the sandwich – Spread mayo or garlic aioli on each bread slice. Place Swiss cheese on both slices, then layer with the beef patty and sautéed mushrooms.
Grill to perfection – Heat a skillet, add oil, and grill the sandwich until the bread is crispy and golden brown. Flip carefully to toast both sides evenly.
Serve and enjoy – Slice in half and indulge in the melty, savory goodness.

Spicy Kick: Add sliced jalapeños or mix sriracha into the mayo.
Caramelized Onion Twist: Replace or add caramelized onions for a richer, slightly sweet flavor.
Cheese Upgrade: Swap Swiss for Gruyère, provolone, or smoked Gouda.
Lighter Option: Use lean ground turkey, chicken, or a plant-based patty.
Garlic Butter Touch: Brush the bread with garlic butter before grilling for extra depth of flavor.

Use a cast-iron skillet for the best crust and even cooking.
Let mushrooms cook undisturbed for a few minutes to get a nice sear before stirring.
Press the sandwich lightly with a spatula while grilling for even browning.
Reduce heat if needed to allow the cheese to melt without burning the bread.
For extra crispiness, lightly toast the bread before assembling the sandwich.

Best Side Pairings: Serve with sweet potato fries, a fresh green salad, or crispy onion rings.
Dipping Sauces: Try Dijon mustard, horseradish mayo, or a creamy garlic aioli.
Beverage Pairings: Pairs well with iced tea, craft beer, or a classic root beer.
