Rye Bread Patty Melt with Secret Sauce
Ingredients
For the Patty Melt
- 1 lb ground beef
- 8 slices rye bread
- 8 slices Swiss cheese
- 1 large onion, thinly sliced
- 4 tbsp butter, plus extra for spreading
- Salt and black pepper, to taste
For the Secret Sauce
- 1/2 cup mayonnaise
- 2 tbsp ketchup
- 1 tbsp pickle relish
- 1 tsp Worcestershire sauce
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- Salt and black pepper, to taste
Instructions
1. Prepare the Secret Sauce
- In a small bowl, combine the mayonnaise, ketchup, relish, Worcestershire sauce, garlic powder, and onion powder.
- Season with salt and pepper to taste and stir until smooth.
- Cover and set aside while you prepare the rest of the sandwich components.
2. Caramelize the Onions
- Melt 1 tbsp of butter in a skillet over medium heat.
- Add the sliced onions, sprinkle with a pinch of salt and pepper, and cook slowly, stirring occasionally.
- Continue cooking for 10–15 minutes, or until the onions are soft, golden, and caramelized.
- Transfer the onions to a plate and set aside.
3. Shape and Cook the Beef Patties
- Divide the ground beef into 4 equal portions and shape into patties slightly larger than your bread slices (they will shrink as they cook).
- Season both sides of each patty with salt and pepper.
- In the same skillet, cook the patties over medium heat for about 4 minutes per side, or until they reach your preferred doneness.
- Remove the patties from the pan and set aside.
4. Assemble the Patty Melts
- Lightly butter one side of each slice of rye bread.
- Place 4 slices on a work surface, buttered side down.
- Spread a generous layer of secret sauce on the unbuttered side of each of these slices.
- Top each with:
- 1 slice of Swiss cheese
- 1 cooked beef patty
- A portion of caramelized onions
- Another slice of Swiss cheese
- Finish with the remaining bread slices, placing them on top with the buttered side facing up.
5. Grill the Sandwiches
- Wipe out the skillet or use a clean one and heat it over medium heat.
- Place the assembled sandwiches in the skillet (work in batches if needed).
- Cook each sandwich for 3–4 minutes per side, or until the bread is crisp and golden and the cheese is fully melted.
- Remove from the skillet, let rest for a minute, then slice and serve warm.
Tips for the Perfect Patty Melt
Choose Quality Ingredients
- Use 80/20 ground beef (80% lean, 20% fat) for juicy, flavorful patties.
- Pick fresh rye bread and good-quality Swiss cheese to maximize flavor and texture.
Caramelize Onions the Right Way
- Keep the heat at medium to medium-low and cook the onions slowly so they soften and sweeten without burning.
- Stir occasionally and add a small splash of water if they start to stick too much.
Handle the Meat Gently
- When forming the patties, avoid packing the meat too tightly.
- Light handling keeps the patties tender instead of dense.
Don’t Skimp on Butter
- Buttering the bread generously helps create that classic crispy, golden crust on the outside of the patty melt.
Press Lightly While Grilling
- Use a spatula to gently press down on the sandwiches while they cook.
- This helps the layers fuse together and ensures even browning, without squeezing out the juices.
Customize the Secret Sauce
- For extra heat, add a few drops of hot sauce.
- For a smoky flavor, mix in a pinch of smoked paprika or chipotle powder.
Variations
Turkey Patty Melt
- Swap the ground beef for ground turkey for a lighter but still satisfying version.
Vegetarian Patty Melt
- Replace the beef patties with plant-based patties (such as Beyond Meat) and use vegan cheese and dairy-free butter if desired.
Spicy Patty Melt
- Add sliced jalapeños or a pinch of red pepper flakes to the sandwich for extra kick.
Mushroom Patty Melt
- Sauté sliced mushrooms along with the onions to add an earthy, umami-rich layer of flavor.
BBQ Patty Melt
- Substitute the secret sauce with your favorite BBQ sauce for a tangy, smoky twist.
Cheese Swaps
- Use cheddar, pepper jack, or provolone instead of Swiss cheese to change up the flavor profile.
Bacon Patty Melt
- Layer in a few strips of crispy bacon for added richness and crunch.
Open-Faced Patty Melt
- Use a single slice of rye bread, top with sauce, patty, onions, and cheese.
- Place under the broiler for a few minutes until the cheese is bubbly and melted.
