Ingredients You’ll Need

Here’s everything you’ll need to make the ultimate patty melt at home. Simple, familiar ingredients with incredible results.

• Ground Beef: The star of the show—use an 80/20 blend for maximum juiciness and flavor.
• Onions: Slowly caramelized to bring out their natural sweetness; a must-have layer in any good patty melt.
• Rye Bread: Traditional and packed with flavor, but feel free to use sourdough or Texas toast if that’s what you have.
• Cheese: Swiss and American are a classic combo—melt beautifully and bring just the right amount of creaminess and tang.
• Butter: For toasting the bread to a perfect golden crisp. Don’t be shy with it!
• Salt and Pepper: Essential for seasoning both the beef and the onions.
• Secret Sauce: A blend of mayo, ketchup, Dijon mustard, pickle relish, garlic powder, and a touch of vinegar—this is what takes it over the top.

Variations

• Different Cheese: Try cheddar for a sharper bite, provolone for a milder melt, or pepper jack for a little heat.
• Add Bacon: Because, why not? Crispy bacon adds a smoky crunch.
• Vegetarian Option: Use a plant-based patty and vegan cheese for a satisfying meat-free version.
• Spicy Kick: Add some sriracha or chipotle powder to the secret sauce for a spicier twist.

How to Make the Ultimate Patty Melt with Secret Sauce

Step 1: Caramelize the Onions

Slice your onions thin and cook them low and slow in a skillet with a little butter or oil. Stir occasionally until they’re golden brown and soft—this takes about 20-25 minutes, but it’s worth every second.

Step 2: Make the Secret Sauce

While the onions are cooking, mix together mayo, ketchup, Dijon mustard, sweet pickle relish, garlic powder, and a splash of white vinegar. Stir until smooth and creamy. Taste and adjust to your liking.

Step 3: Shape and Cook the Patties

Form the ground beef into thin, wide patties (they should match the shape of your bread). Season well with salt and pepper. Cook them in a skillet over medium-high heat until browned and cooked through—about 3–4 minutes per side.

Step 4: Assemble the Sandwiches

Spread a layer of the secret sauce on one side of each slice of bread. On the non-sauced side of one slice, add a slice of cheese, a beef patty, caramelized onions, another slice of cheese, then top with the second piece of bread (sauce side in).

Step 5: Grill to Perfection

Melt a little butter in a clean skillet over medium heat. Grill the sandwich on both sides until the bread is golden and the cheese is gooey—press down slightly to help everything meld together.

Step 6: Serve and Enjoy

Slice diagonally for that diner-style presentation and serve hot. Don’t forget extra sauce on the side for dipping!

Pro Tips for Making the Recipe

• Don’t Rush the Onions: Take your time with caramelizing. It’s what gives this sandwich its signature sweet-savory depth.
• Use Thin Patties: Thinner patties ensure every bite has a perfect meat-to-cheese-to-bread ratio.
• Press While Grilling: Lightly pressing the sandwich in the pan helps melt the cheese and create a crisp crust.
• Toast the Bread Separately First (Optional): For an even crunchier sandwich, toast each slice before assembling and grilling.

How to Serve

This patty melt is a meal in itself, but here are a few fun ways to serve it up:

Classic Combo:

Serve with crispy French fries or onion rings for that true diner feel.

Lighter Sides:

Pair with a crisp side salad or coleslaw to balance out the richness.

Dipping Game:

Extra secret sauce on the side is a must. Or try a tangy BBQ sauce or spicy aioli for fun.

Make Ahead and Storage

Storing Leftovers

Wrap leftovers tightly in foil or store in an airtight container in the fridge for up to 2 days.

Freezing

You can freeze assembled (but ungrilled) sandwiches. Wrap tightly in plastic and foil, then freeze for up to 1 month. Thaw overnight in the fridge before grilling.

Reheating

Reheat in a skillet over low heat until warmed through and crisp, or use a toaster oven for a quick fix. Avoid the microwave—it’ll make the bread soggy.

FAQs

Can I use different bread for the patty melt?
Absolutely. While rye is classic, sourdough, brioche, or Texas toast all work wonderfully. Just make sure it’s sturdy enough to hold all the gooey goodness.

What’s in the secret sauce?
The secret sauce is a mix of mayo, ketchup, Dijon mustard, sweet relish, garlic powder, and vinegar. It’s tangy, creamy, and a little sweet—perfect for balancing the savory sandwich.

Can I make this ahead of time?
Yes! You can prep the sauce and caramelized onions in advance. You can even shape the patties ahead. Just assemble and grill when you’re ready to eat.

What kind of cheese melts best for a patty melt?
American cheese melts incredibly well and adds a creamy texture, while Swiss gives a nice nutty flavor. Combine the two for a perfect balance, or use your favorite melty cheese.
