Ingredients
List of Ingredients for Grilled Patty Melt
– 1 pound ground beef (80/20 blend)
– 4 slices of hearty rye bread
– 4 slices of Swiss cheese
– 1 large onion, thinly sliced
– 2 tablespoons unsalted butter, divided
– 1 tablespoon olive oil
– Salt and pepper to taste

When I make a grilled patty melt, the right ingredients make all the difference. The beef is key. I use an 80/20 blend for flavor and juiciness. Rye bread is my go-to because it adds depth and texture. Swiss cheese melts beautifully, giving that creamy goodness we crave.
The onion is a game changer. When you slice it thin, it caramelizes perfectly. I cook it until it’s golden and sweet. The butter and olive oil help bring out its rich flavor. Don’t forget salt and pepper for seasoning. They bring out the best in meat and onions.
Now, let’s talk about the secret sauce. This sauce is what makes the melt special. It combines mayonnaise, Dijon mustard, ketchup, and sweet pickle relish. The garlic and onion powder add layers of taste. Smoked paprika gives it a subtle kick. Mix these well, and let it chill. This helps the flavors mingle and become even tastier.
With these ingredients, you’re set for a delicious grilled patty melt that is sure to impress!

Step-by-Step Instructions
Preparing the Secret Sauce
To start, grab a small bowl. Add these ingredients:
– 1/4 cup mayonnaise
– 1 tablespoon Dijon mustard
– 1 tablespoon ketchup
– 1 tablespoon sweet pickle relish
– 1 teaspoon garlic powder
– 1 teaspoon onion powder
– 1 teaspoon smoked paprika
Mix all these together until smooth. Cover the bowl and put it in the fridge. This helps the flavors blend nicely while you cook the rest.
Cooking the Onions
Next, heat a large skillet over medium heat. Add 1 tablespoon of olive oil. Once hot, toss in your thinly sliced onion. Sauté them for about 10-15 minutes. Stir occasionally. You want them to turn a deep golden brown. Add a pinch of salt, then set them aside.
Forming and Grilling the Patties
Now it’s time for the beef. Divide 1 pound of ground beef into four equal parts. Shape each part into a patty, about ½ inch thick. Season both sides with salt and pepper. Preheat your grill or skillet over medium-high heat. Cook the patties for 3-4 minutes on each side for medium-rare. In the last minute, add a slice of Swiss cheese on each patty. Cover to help the cheese melt.
Toasting the Rye Bread
In a new skillet, melt the remaining 1 tablespoon of butter over medium heat. Place two slices of rye bread in the skillet. Spread a spoonful of your secret sauce on top of the bread. When the bottom is golden brown, flip the bread and repeat on the other side. Remove it from the skillet and set aside. Do the same for the remaining bread slices.
Assembling the Patty Melt
Take one slice of toasted rye and put it on a plate. Layer a cheesy beef patty on top, then add a spoonful of caramelized onions. Place another slice of toasted rye on top. Spread some secret sauce on that slice for extra flavor.
Final Grilling and Serving
Put the assembled sandwich back in the skillet. If needed, add a bit more butter. Grill each side for 2-3 minutes until the bread is crispy and golden brown. Everything should be hot. Once done, slice the sandwiches in half and serve right away. For a nice touch, add extra secret sauce on the side for dipping. Enjoy your delicious grilled patty melt!
Tips & Tricks
Achieving Perfectly Grilled Patties
To make great grilled patties, start with good seasoning. I use salt and pepper. Season both sides of the beef well. This simple step boosts flavor. You can also mix in herbs or spices if you like.
For even cooking, preheat your grill or skillet. Aim for medium-high heat. Place patties gently on the grill. Don’t press down on them; this keeps juices inside. Cook for 3-4 minutes on each side for medium-rare. Adjust the time for your preferred doneness.
Enhancing Your Secret Sauce
The secret sauce is key to flavor. You can try different ingredients to make it your own. For a spicy kick, add hot sauce or cayenne pepper. If you want it sweeter, mix in more relish.
You can also add fresh herbs like dill or parsley for a twist. Experiment with these options to find your favorite. The more you personalize it, the better it gets!
Best Bread Choices for Patty Melts
For the bread, I recommend hearty rye. It adds great flavor and texture. You can also use sourdough or whole wheat bread. Both are tasty and hold up well.
If you want an alternative to rye, try ciabatta or even a bagel. These choices make the sandwich unique. Remember, the bread should be sturdy enough to hold the filling.
Pro Tips
- Use High-Quality Beef: For the best flavor and juiciness, opt for a freshly ground beef blend with a higher fat content, like 80/20.
- Perfectly Caramelize Onions: Low and slow is the key! Sauté onions on medium-low heat for a deeper, sweeter flavor and avoid burning.
- Toast the Bread Well: Make sure the bread is well-toasted before assembling the sandwich; this will help keep it crisp and prevent sogginess.
- Customize Your Secret Sauce: Feel free to adjust the ingredients in the secret sauce to suit your taste; adding a dash of hot sauce can give it a nice kick!

Variations
Vegetarian Patty Melt Options
You can make a tasty vegetarian patty melt. Use black bean or veggie patties instead of beef. They add a nice texture and flavor. For cheese, try mozzarella or cheddar. These options melt well and taste great.
Customizing Toppings
You can add more toppings to your patty melt. Consider crispy bacon or sautéed mushrooms. They add depth and richness. You can also try other spreads. A bit of avocado or spicy mustard boosts flavor.
Different Cheese Choices
Swiss cheese is classic, but there are many choices. You can use sharp cheddar or pepper jack for a kick. Mixing cheeses gives a unique taste. Try combining mozzarella and gouda for a creamy blend.
Storage Info
Storing Leftover Patty Melts
To keep your leftover patty melts fresh, store them in an airtight container. Place parchment paper between layers to prevent sticking. Refrigerate them within two hours of cooking. This will help keep the flavors intact and maintain texture.
When you’re ready to eat, reheating properly is key. Use a skillet over low heat. This helps avoid dry patties. Heat for about 5-7 minutes. Flip them halfway through to warm evenly. You can also cover the skillet to trap moisture. For extra flavor, add a little butter while reheating.
Keeping Secret Sauce Fresh
For your secret sauce, proper storage is essential. Transfer it to a clean, airtight container. Keep it in the fridge right after making it. This prevents bacteria and keeps the sauce tasty.
The shelf life of the sauce is about one week. If you notice any changes in smell or color, it’s best to discard it. For longer storage, consider freezing in small portions. This way, you can enjoy it anytime without losing flavor.
