How to Make It

Create mouthwatering burgers by following these detailed steps:

Whisk the sauce

In a medium mixing bowl, whisk together mayonnaise, ketchup, mustard, garlic powder, salt, and black pepper until a smooth, tangy secret sauce forms. Refrigerate the sauce for at least 15 minutes to allow flavors to meld and intensify.

Prepare the beef

Divide the ground beef into 4-ounce portions, gently rolling each into loose spheres. Generously season each beef ball with kosher salt and freshly cracked black pepper.

Heat the skillet

Heat a cast-iron skillet or heavy griddle over high heat until smoking.

Smash and cook patties

Place the beef balls onto the scorching surface and immediately press down firmly with a sturdy spatula, creating thin, crispy-edged patties approximately 1/4 inch thick. Cook patties for 2 minutes on the first side, allowing a rich golden-brown crust to develop. Flip and cook an additional 1-2 minutes for medium doneness, ensuring a juicy interior while maintaining crisp exterior edges.

Toast the buns

While the patties rest, lightly toast the burger buns until golden and slightly crisp.

Assemble the burgers

Spread a generous layer of prepared secret sauce on both the top and bottom bun surfaces. Layer crisp lettuce leaves, sliced ripe tomatoes, thinly sliced red onions, and tangy dill pickle rounds onto the bottom bun. Place hot smashed patties directly on top of the vegetable bed.

Top the burgers

Crown the burger with the sauce-coated top bun, pressing gently to meld all flavors. Slice diagonally and serve immediately with additional secret sauce on the side.

How to Store It

Fridge: up to 3 days in an airtight container.
Freezer: no, to maintain texture.
Reheat: microwave for 30-45 seconds as needed.

Tips for Best Results

• Use a high-fat ground beef for extra juiciness and flavor.
• Let the crushed patties rest for a minute before serving for better texture.
• Adjust seasoning in the secret sauce to your taste, adding more garlic or mustard if desired.

Serving Suggestions

• Pair with crispy fries or onion rings for a classic combo.
• Serve alongside a light salad for a complete meal.
• Enjoy with a cold beer or a fizzy soda for a perfect summer treat.
