- Shape meat gently into patties. Make edges slightly thicker. Season just before cooking. Cook without moving until browned.
- Step 3: Building the Sandwich
- Toast rye until golden. Layer cheese against bread. Add onions evenly. Press sandwich lightly.

The secret to exceptional patty melts lies in properly caramelized onions. This slow process develops deep, rich flavors that elevate the entire sandwich.
Quality ingredients handled with proper technique create a patty melt that's far more than just a burger on toast. Each component plays an essential role.
Fresh rye bread provides the perfect foundation, offering a subtle sourness that balances the rich beef and sweet onions.

A well-made patty melt combines familiar comfort food elements with precise cooking techniques. When done right, it delivers a deeply satisfying blend of flavors and textures.
