Ingredients
Method
Preparation
- Heat a skillet over medium heat.
- Melt the butter and add the sliced onions. Cook until they are caramelized and fragrant.
- Season the hamburger patty with salt and pepper, then cook it in the skillet to your desired doneness.
Assembly and Cooking
- Assemble the sandwich: Place one slice of bread in the skillet, add cheese, the cooked patty, caramelized onions, and then top with another slice of cheese and the second slice of bread.
- Grill the sandwich until golden brown on both sides and the cheese is melted.
- Serve hot.
Notes
Don’t rush the onions: Caramelizing them takes time but adds major flavor. You can switch up your cheese to Swiss or provolone for a different taste. Generously butter your bread for that crispy exterior everyone loves!
