Patty Melt with Secret Sauce

Featured in Simple and Satisfying Dinners.

A patty melt with secret sauce takes the classic grilled sandwich to new heights. The beef patty is seasoned with worcestershire sauce and cooked until perfectly browned, then topped with sweet caramelized onions that slowly cook until deep golden. Two types of cheese - swiss and cheddar - create the perfect melty layer. The secret sauce combines mayo, ketchup, dijon, and pickle juice for a tangy kick. Everything gets pressed between buttery grilled rye bread until golden brown and crispy. This diner favorite takes about an hour to make but most of that time is spent letting the onions caramelize to sweet perfection.

The patty melt stands as a testament to diner cuisine perfection - a harmonious blend of juicy beef, sweet caramelized onions, and melted cheese, all embraced by golden-toasted rye bread. While seemingly simple, mastering this sandwich requires attention to detail and patience, particularly with those slowly caramelized onions that make this dish truly special.

After years of perfecting this recipe, I've found that the key lies in taking your time with each component. My family knows dinner will be exceptional when they smell onions slowly caramelizing on the stove.

Essential Ingredients For Success

  • Ground beef: Select ground beef with the right fat content (85/15 is ideal) - it provides necessary moisture and flavor
  • Rye bread: Fresh rye bread should be sturdy enough to hold up to grilling - look for artisanal varieties if possible
  • Swiss cheese: Offers nutty depth
  • Cheddar cheese: Brings sharp tang
  • Sweet onions: Vidalia or Spanish onions caramelize beautifully
  • Real butter: Not margarine, creates that essential golden crust
  • Fresh pickle juice: Adds brightness to the secret sauce that bottled versions can't match

Creating The Perfect Patty Melt

The Art Of Onion Caramelization
Begin with your onions - they'll take the longest but require minimal attention. Slice them evenly, add a pinch of salt, and let them slowly transform over low heat. Patience here is rewarded with incredibly sweet, golden results.
Perfecting The Patty
Shape your patties slightly larger than your bread, as they'll shrink during cooking. Press a small dimple in the center to prevent bulging. Season generously just before cooking - this creates the best crust.
Building Your Masterpiece
Start with well-buttered rye bread - the butter should reach every corner. Layer strategically: bread, cheese, patty, onions, more cheese, sauce, top bread. This order ensures everything melds together perfectly.

About The Sauce

The secret sauce has become a favorite in my household - my kids now request it for everything from fries to vegetables. Its tangy-sweet profile complements so many dishes.

The balance of ingredients in the secret sauce is crucial. Start with equal parts mayo and ketchup, then adjust other ingredients to taste. The pickle juice might seem unusual, but it's the key to that classic diner tang.

Temperature Control

Maintaining the right heat is crucial throughout cooking. Too hot, and you'll burn the bread before the cheese melts; too cool, and you'll miss that perfect golden crunch.

Make-Ahead Options

While best served fresh, you can prepare components in advance. The secret sauce actually improves after a day in the fridge, and caramelized onions can be made ahead and reheated.
