French Onion Patty Melt

The French Onion Patty Melt is a mouthwatering twist on the classic patty melt, elevating it with the rich and savory flavors of French onion soup. This hearty sandwich features a seasoned beef patty, caramelized onions, melted Swiss cheese, and slices of buttery toasted rye bread, creating a comforting and indulgent meal.

To craft this delectable patty melt, gather the essential ingredients. Ground beef is seasoned and shaped into patties, while onions are slowly caramelized to bring out their natural sweetness. Swiss cheese, known for its creamy texture and nutty flavor, adds a melty richness to the sandwich. Rye bread, with its robust flavor, serves as the perfect base for this flavorful creation.

The preparation process begins by shaping the seasoned ground beef into patties and cooking them to your preferred level of doneness. Simultaneously, the onions are sautéed until golden brown and caramelized, enhancing their sweetness. Once the patties are cooked, they are layered with the caramelized onions and Swiss cheese. The assembly is then sandwiched between slices of rye bread, creating a delightful stack.

The sandwich is grilled or pan-fried until the bread is golden brown and the cheese has melted into a gooey perfection, infusing the patty with savory flavors. The French Onion Patty Melt is then sliced and served hot, offering a satisfying combination of savory beef, sweet caramelized onions, and melty Swiss cheese, all enveloped in the buttery crunch of toasted rye bread.



3 tablespoons butter
3 yellow onions, sliced thin
2 pounds ground beef
1 tablespoon ketchup
½ teaspoon garlic powder
1 teaspoon salt
½ teaspoon pepper
2 cups Gruyere cheese, shredded
12 slices Texas toast
8 teaspoons mayonnaise


1/3 cup mayonnaise
1 tablespoon lemon juice
1 teaspoon pepper
One tablespoon (about 3 gloves) garlic, minced
1 teaspoon fresh parsley
1 tablespoon ketchup


In a medium skillet, melt butter over medium-low heat. Add onions and cook until caramelized (about 15-20 minutes), stirring often. Add water as needed to prevent burning. Remove from skillet and tent to keep warm.
In a large bowl, mix together ground beef, garlic powder, salt, and pepper.
Make 8 square patties (a little larger than the bread). Each patty should be about ¼ inch thick.
Wipe out the skillet and set the heat to medium-high. Add the hamburger patties in batches (two at a time) and cook 1-2 minutes per side. Remove patties from the skillet and set aside.
Toast 4 pieces of the Texas toast and set aside.
Meanwhile, in a small bowl, combine the mayonnaise, lemon juice, pepper, garlic, parsley, and ketchup to make the aioli spread.
Top 4 untoasted slices of bread with cheese, hamburger patty, onions, toast that has aioli spread on both sides, more cheese, a second beef patty, more onions, and top with a slice of bread.
Spread 1 teaspoon of mayonnaise on the top.
Wipe out skillet and set heat to medium. Add sandwiches to the pan, mayo side down. Place a weighted pan on top to hold the sandwich firmly in the pan. Cook until golden brown (about 3 minutes). Remove the weighted pan. Spread 1 teaspoon of mayo on the top slice of bread and flip carefully. Cook for 3 additional minutes (or until golden brown). Serve warm.

In conclusion, the French Onion Patty Melt is a deliciously indulgent take on the classic patty melt, inspired by the flavors of French onion soup. This sandwich is a comfort food delight, perfect for a hearty lunch or dinner. Now, let’s explore the step-by-step process of creating this mouthwatering French Onion Patty Melt in your own kitchen.
