Ingredients
For the Patty

How to Make French Onion Patty Melt
Step 1: Caramelize the Onions
In a skillet over medium heat, sauté 2 medium sweet onions, adding a pinch of salt until they turn golden brown and develop sweetness. This process takes about 15 minutes; remember to stir occasionally to prevent burning.
Step 2: Prepare the Beef Patties
While the onions are cooking, shape 1 lb ground beef into four patties that are about 1 inch thick. Season each patty with salt and pepper to enhance their flavor.
Step 3: Cook the Patties
Increase the heat to medium-high and cook each patty in the skillet for about 4-5 minutes per side. Adjust cooking time based on your preferred level of doneness.
Step 4: Assemble the Sandwiches
On one slice of rye bread, layer one cooked patty, followed by caramelized onions, and two slices of Swiss cheese. Top with another slice of rye bread to complete each sandwich.
Step 5: Grill the Sandwiches
In the same skillet used for cooking, melt 4 tbsp butter over medium heat. Grill each sandwich until they are golden brown and crispy on both sides while ensuring that the cheese melts completely. This should take about 3-4 minutes per side.

Common Mistakes to Avoid
When making a French Onion Patty Melt, it’s easy to overlook some key steps. Here are common mistakes and how to avoid them.
- Skipping onion caramelization: Failing to properly caramelize the onions can lead to a less flavorful sandwich. Take your time and stir them often for that sweet, golden result.
- Overcooking the patties: Cooking the beef patties too long can dry them out. Use a meat thermometer to check for doneness and remove them when they reach your desired level.
- Neglecting cheese melting: If the cheese isn’t melted thoroughly, you won’t get that gooey texture you crave. Cover the skillet with a lid during grilling to trap heat and melt the cheese faster.
- Using stale bread: Old or stale bread won’t hold up well in a patty melt. Always use fresh rye bread for optimal crunch and flavor.
- Not seasoning properly: Underseasoned ingredients can make your sandwich bland. Don’t hesitate to season each component, especially the beef patties, with salt and pepper.
