Patty melts with special sauce are a delightful twist on the classic burger. Combining juicy ground beef patties, caramelized onions, and melted swiss cheese between slices of buttery rye bread, this sandwich is a comfort food favorite. The special sauce adds an extra layer of flavor that makes each bite irresistible.
While most of the ingredients for this recipe are common pantry items, you might need to pick up rye bread and swiss cheese if they are not staples in your home. Additionally, worcestershire sauce and dijon mustard are essential for the special sauce, so make sure to grab those if you don't already have them.

Ingredients For Patty Melts With Special Sauce

Technique Tip for This Recipe
When caramelizing onions, ensure you cook them slowly over medium heat to bring out their natural sweetness. Stir occasionally to prevent burning and achieve a deep, rich color. This process can take a bit longer than 10 minutes, so be patient. The result will add a wonderful depth of flavor to your patty melts.

How to Store or Freeze This Dish
Allow the patties and caramelized onions to cool completely before storing. This prevents condensation, which can make the bread soggy.
Wrap each patty melt individually in aluminum foil or plastic wrap. This helps maintain their shape and prevents them from sticking together.
Place the wrapped patty melts in an airtight container or a resealable plastic bag. This adds an extra layer of protection against freezer burn and keeps them fresh.
Label the container or bag with the date. This ensures you know how long they’ve been stored and helps you use them within the recommended time frame.
Store the special sauce separately in a small airtight container. This keeps it fresh and prevents the bread from becoming soggy during storage.
For freezing, place the wrapped patty melts in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
Once frozen, transfer the patty melts to a resealable freezer bag or airtight container. This saves space and keeps them organized.
When ready to reheat, thaw the patty melts in the refrigerator overnight. This ensures even reheating and maintains the texture.
Reheat the patty melts in a skillet over medium heat until the bread is crispy and the cheese is melted, about 3-4 minutes per side. This brings back the delicious, freshly-made taste.
Serve with the special sauce on the side or spread it on the patty melts after reheating. This keeps the sauce fresh and flavorful.
How to Reheat Leftovers
Preheat your oven to 350°F. Wrap each patty melt in aluminum foil to keep it moist. Place the wrapped sandwiches on a baking sheet and heat for about 10-15 minutes, or until the cheese is melted and the bread is crispy.
For a quicker method, use a skillet. Heat a non-stick skillet over medium heat. Place the patty melt in the skillet and cover with a lid. Cook for about 3-4 minutes on each side, or until the cheese is melted and the bread is golden brown.
If you have an air fryer, preheat it to 350°F. Place the patty melt in the basket and cook for about 5-7 minutes, checking halfway through to ensure even heating.
For a microwave option, place the patty melt on a microwave-safe plate. Cover it with a damp paper towel to prevent the bread from drying out. Microwave on medium power for 1-2 minutes, or until the cheese is melted and the patty is heated through. Note that this method may result in a less crispy bread.
Toaster ovens are also a great option. Preheat to 350°F and place the patty melt on the rack. Heat for about 10 minutes, or until the cheese is melted and the bread is crispy.
