Instructions
Caramelize the Onions
In a skillet over medium-low heat, melt butter and add sliced onions. Cook slowly, stirring occasionally, until onions are golden and caramelized. Add a pinch of brown sugar for extra sweetness. Set aside.
Make the Secret Sauce
In a small bowl, mix mayonnaise, ketchup, Dijon mustard, pickle relish, and smoked paprika. Stir well and refrigerate until ready to use.
Prepare the Beef Patties
In a bowl, mix ground beef with Worcestershire sauce, salt, pepper, and garlic powder. Shape into thin patties, slightly larger than your bread slices (they’ll shrink as they cook).
Cook the Patties
Heat a skillet over medium-high heat. Cook patties for about 3–4 minutes per side until browned and cooked through. Set aside.
Assemble the Patty Melt
Butter one side of each bread slice. On the unbuttered side, layer cheese, a cooked patty, caramelized onions, and more cheese. Spread a generous amount of secret sauce on the top slice before placing it on the sandwich, butter-side up.
Grill to Perfection
In the same skillet over medium heat, grill sandwiches for 2–3 minutes per side, pressing gently until the bread is golden brown and the cheese is melty.
Serve & Enjoy
Let cool slightly, then slice and serve with extra secret sauce for dipping!
How to Serve Patty Melts
With Fries: Classic diner-style—serve with crispy fries or onion rings.
Dill Pickles: The tangy crunch pairs perfectly with the richness of the melt.
Coleslaw: A fresh, crisp side to balance the flavors.
Tomato Soup: Dunking a patty melt into warm tomato soup? Perfection!
Additional Tips
Use Good Bread: Sourdough, rye, or Texas toast works best for that crispy texture.
Don’t Rush the Onions: Low and slow is key for sweet, caramelized perfection.
Press While Grilling: A gentle press with a spatula helps the bread get evenly crispy.
Switch Up the Cheese: Swap Swiss for cheddar, provolone, or even pepper jack for a spicy kick.
Make It Spicy: Add a dash of hot sauce to the secret sauce or sprinkle red pepper flakes on the patties.
