Patty Melt Secret Sauce this Recipe

Ingredients:

  • For the Patty:
    • 1.5 pounds ground beef (80/20 blend recommended for flavor and juiciness)
    • 1 tablespoon Worcestershire sauce
    • 1 teaspoon garlic powder
    • 1 teaspoon onion powder
    • 1/2 teaspoon smoked paprika
    • 1/2 teaspoon black pepper
    • 1/4 teaspoon salt (or to taste)
  • For the Caramelized Onions:
    • 2 large yellow onions, thinly sliced
    • 2 tablespoons butter
    • 1 tablespoon olive oil
    • 1/2 teaspoon sugar
    • 1/4 teaspoon salt
    • 1/4 cup beef broth (optional, for deglazing)
  • For the Secret Sauce:
    • 1/2 cup mayonnaise
    • 2 tablespoons ketchup
    • 1 tablespoon yellow mustard
    • 1 tablespoon sweet pickle relish
    • 1 teaspoon Worcestershire sauce
    • 1/2 teaspoon garlic powder
    • 1/4 teaspoon smoked paprika
    • Pinch of cayenne pepper (optional, for a little heat)
  • For the Assembly:
    • 8 slices rye bread (or your favorite bread for grilling)
    • 8 slices Swiss cheese
    • 4 tablespoons butter, softened (for grilling the sandwiches)

Preparing the Patty Melts

Making the Burger Patties

  1. In a large bowl, gently combine the ground beef, Worcestershire sauce, garlic powder, onion powder, smoked paprika, black pepper, and salt. Be careful not to overmix, as this can result in tough patties. I like to use my hands for this, but a spatula works too!
  2. Divide the mixture into 4 equal portions. Gently form each portion into a patty, about 1/2 inch thick and slightly larger than the bread slices (they will shrink a bit during cooking). I usually flatten them out a bit more in the center to prevent them from bulging as they cook.
  3. Pro Tip: Make a small indentation in the center of each patty with your thumb. This helps prevent the patties from puffing up in the middle while cooking, ensuring even cooking.

Caramelizing the Onions

  1. Heat the butter and olive oil in a large skillet over medium-low heat. The key here is low and slow!
  2. Add the sliced onions to the skillet and sprinkle with sugar and salt. Stir to coat the onions evenly.
  3. Cook the onions, stirring occasionally, for about 30-45 minutes, or until they are deeply golden brown and caramelized. Be patient! This process takes time, but it’s worth it. The natural sugars in the onions will break down and create a sweet, savory flavor.
  4. If the onions start to stick to the bottom of the skillet, deglaze with the beef broth (if using). Scrape up any browned bits from the bottom of the pan. This adds extra flavor to the onions.
  5. Once the onions are caramelized to your liking, remove them from the skillet and set aside.

Mixing the Secret Sauce

  1. In a small bowl, whisk together the mayonnaise, ketchup, yellow mustard, sweet pickle relish, Worcestershire sauce, garlic powder, smoked paprika, and cayenne pepper (if using).
  2. Taste and adjust the seasonings as needed. I sometimes add a little extra relish for sweetness or a dash of hot sauce for more heat.
  3. Cover the bowl and refrigerate the sauce for at least 30 minutes to allow the flavors to meld. This step is important for developing the best flavor.

Cooking the Patty Melts

  1. Heat a large skillet or griddle over medium heat. You can use the same skillet you used for the onions, just wipe it clean first.
  2. Cook the burger patties for about 4-5 minutes per side, or until they are cooked through and reach an internal temperature of 160°F (71°C). Use a meat thermometer to ensure they are cooked safely.
  3. During the last minute of cooking, place two slices of Swiss cheese on top of each patty to allow the cheese to melt.
  4. Remove the patties from the skillet and set aside.

Assembling the Patty Melts

  1. Spread softened butter on one side of each slice of rye bread.
  2. Place four slices of bread, butter-side down, in the same skillet you used to cook the patties.
  3. Spread a generous amount of the secret sauce on the unbuttered side of each slice of bread.
  4. Top each slice of bread with a cheesy burger patty, a generous portion of caramelized onions, and another slice of Swiss cheese.
  5. Place the remaining slices of bread on top, butter-side up.
  6. Cook the patty melts for about 3-4 minutes per side, or until the bread is golden brown and the cheese is melted and gooey. Press down gently on the sandwiches with a spatula to ensure even browning.
  7. Remove the patty melts from the skillet and let them cool for a minute or two before slicing in half.
  8. Serve immediately and enjoy! I like to serve mine with a side of crispy fries or onion rings.

Tips for the Perfect Patty Melt

  • Don’t Overcrowd the Pan: Cook the patties in batches if necessary to avoid overcrowding the pan, which can lower the temperature and result in uneven cooking.
  • Use Quality Ingredients: The better the ingredients, the better the patty melt will taste. Use good quality ground beef, cheese, and bread.
  • Adjust the Seasonings: Feel free to adjust the seasonings in the patties and secret sauce to your liking. Add more garlic powder, onion powder, or smoked paprika for extra flavor.
  • Get Creative with the Cheese: While Swiss cheese is traditional, you can experiment with other cheeses like Gruyere, provolone, or even cheddar.
  • Make it Vegetarian: Substitute the ground beef with plant-based burger patties for a vegetarian option.
  • Make it Gluten-Free: Use gluten-free bread to make this recipe gluten-free.

Variations

  • Spicy Patty Melt: Add a pinch of cayenne pepper or a dash of hot sauce to the secret sauce for a spicy kick. You can also use pepper jack cheese for extra heat.
  • Bacon Patty Melt: Add crispy bacon to the patty melt for a smoky, savory flavor.
  • Mushroom Patty Melt: Sauté sliced mushrooms with the onions for a delicious earthy flavor.
  • Jalapeño Patty Melt: Add sliced jalapeños to the patty melt for a spicy and tangy flavor.
  • Open-Faced Patty Melt: Serve the patty melt open-faced for a lighter option.

Make-Ahead Tips

  • Caramelized Onions: The caramelized onions can be made ahead of time and stored in the refrigerator for up to 3 days.
  • Secret Sauce: The secret sauce can also be made ahead of time and stored in the refrigerator for up to 5 days.
  • Burger Patties: The burger patties can be formed ahead of time and stored in the refrigerator for up to 24 hours.

Storage Instructions

  • Leftover Patty Melts: Leftover patty melts can be stored in the refrigerator for up to 2 days. Reheat them in a skillet or microwave.
