Step-by-Step Instructions
Step 1: Mix the secret sauce
In a small bowl, stir together the mayonnaise, ketchup, finely chopped dill pickles or relish, yellow mustard, white vinegar, smoked paprika, garlic powder, and black pepper until smooth and evenly combined. Cover and refrigerate for at least 10 minutes while you prepare the rest of the recipe. This short rest helps the sauce taste more rounded and diner-style.
Step 2: Grill the onions until soft and browned
Set a large cast-iron skillet, stainless-steel skillet, or flat-top griddle over medium heat, about 325°F to 350°F. Add 1 tablespoon butter and 1 teaspoon oil. When the butter melts and begins to foam, add the sliced onion and 1/4 teaspoon kosher salt. Cook for 10 to 12 minutes, stirring every 1 to 2 minutes, until the onions are soft, golden, and lightly browned at the edges. If the pan gets too dark, add 1 tablespoon water and scrape up the browned bits. Transfer the onions to a bowl and keep them warm.
Step 3: Portion the beef
While the onions cook, divide the cold ground beef into 8 equal portions, 2 ounces each. Gently shape each portion into a loose ball without packing it tightly. For the best thin seared patties, keep the beef loose and cold; this helps the edges brown quickly while the inside stays juicy. Do not season the beef yet, because salt can draw out moisture if it sits too long.
Step 4: Toast the buns
Increase the griddle or skillet heat to medium-high, about 375°F to 400°F. Spread the cut sides of the buns with 2 tablespoons softened butter. Place the buns cut-side down and toast for 1 to 2 minutes, until golden and lightly crisp. Transfer the buns to a plate. Toasting the buns gives the burger structure and keeps the sauce from soaking in too quickly.
Step 5: Sear the first side of the patties
Raise the heat to high enough to hold the cooking surface near 400°F. Lightly oil the cooking surface only if needed. Working in batches if your pan is crowded, place the beef balls on the hot surface, leaving several inches between them. Immediately press each ball into a thin patty about 4 inches wide using a sturdy metal spatula or burger press. For easier pressing, place a small square of parchment paper over the beef before pressing, then peel it away. Season the patties with some of the kosher salt and black pepper. Cook undisturbed for 2 minutes, until the undersides are deeply browned and the edges look crisp.
Step 6: Flip, add cheese, and stack
Use a thin metal spatula to firmly scrape under each patty so you keep the browned crust intact. Flip the patties, season the second side with the remaining salt and pepper, and immediately place 1 slice of American cheese on each patty. Cook for 1 1/2 to 2 minutes more, until the cheese is melted and the patties reach an internal temperature of 160°F. Stack two cheesy patties together for each burger while they are still on the griddle, then transfer the stacks to a plate.
Step 7: Build the double patty diner burgers
Spread about 1 tablespoon secret sauce on each bottom bun. Add 4 dill pickle chips to each burger, then place one double stack of cheesy patties on top. Spoon a generous portion of grilled onions over the cheese, drizzle each burger with 1 teaspoon yellow mustard, and spread another 1/2 tablespoon secret sauce on the top bun. Close the burgers and serve immediately while the patties are hot, the cheese is melty, and the buns are crisp.
Pro Tips
- Use 80/20 beef: The fat content is important for juicy thin patties with crisp, browned edges.
- Cook hot and fast: A 400°F cooking surface gives you that diner-style sear before the patties overcook.
- Do not overwork the beef: Loose portions press into tender patties; tightly packed beef can turn dense.
- Scrape confidently when flipping: The best browned crust sticks slightly to the pan, so slide the spatula firmly underneath to lift it all.
- Assemble right away: Thin patties are best eaten immediately while the edges are crisp and the cheese is melted.
Variations
- Spicy diner burger: Add 1 teaspoon hot sauce and 1/8 teaspoon cayenne pepper to the secret sauce, then top each burger with pickled jalapenos.
- Classic mustard-griddled style: After smashing the patties, spread 1/2 teaspoon yellow mustard over each raw top side before flipping for a tangy, caramelized crust.
- Extra onion burger: Press 2 tablespoons very thinly sliced raw onion directly into each patty right after smashing, then cook and flip as directed.
Storage & Make-Ahead
These burgers are best served fresh, but you can make the secret sauce up to 5 days ahead and store it covered in the refrigerator. The onions can be cooked up to 3 days ahead; refrigerate them in an airtight container and rewarm in a skillet over medium-low heat for 3 to 4 minutes. Cooked patties can be refrigerated for up to 3 days, but they will lose some crispness. Reheat patties in a covered skillet over medium-low heat for 2 to 3 minutes, or until hot. For the best texture, toast the buns and assemble the burgers just before serving.
