FAQs
Can I make the smash burger patties ahead of time?
Yes, you can form the beef into balls and season them a few hours ahead, but it’s best to smash and cook the patties just before serving to maintain their crispy edges and juiciness.
What can I substitute for pickle juice in the secret sauce?
If you don’t have pickle juice on hand, a teaspoon of vinegar (apple cider or white) plus a pinch of sugar can mimic the tangy flavor well in the sauce.

Ingredients
Burger
- 1 lb 80/20 ground beef
- 1 tsp salt
- 1/2 tsp black pepper
- 4 slices American cheese
- 4 brioche buns
- Toppings: lettuce, tomato slices, pickles, onions
Secret Sauce
- 1/2 cup mayonnaise
- 2 tbsp ketchup
- 1 tbsp Dijon mustard
- 1 tbsp pickle juice
Instructions
- Preheat the grill or skillet: Heat your grill or a heavy skillet over medium-high heat until it is hot enough to sear the burgers, about 5 minutes.
- Make the secret sauce: In a small bowl, whisk together mayonnaise, ketchup, Dijon mustard, and pickle juice until well combined. Set aside.
- Prepare the beef balls: Divide the ground beef into four equal portions and gently form each into a loose ball without compacting too tightly. Season generously with salt and black pepper on all sides.
- Smash the patties: Place each beef ball on the hot grill or skillet. Using a sturdy spatula or a burger press, firmly smash down each ball to form thin patties. Cook undisturbed for about 3 minutes until crispy edges develop.
- Flip and add cheese: Carefully flip each patty and immediately place a slice of American cheese on top. Cook for an additional minute, until the cheese is melted and the patty is cooked through.
- Assemble the burgers: Lightly toast the brioche buns if desired. Spread a generous amount of secret sauce on the top and bottom buns. Layer the bottom bun with lettuce, tomato slices, pickles, and onions, then add the cheesy burger patty. Top with the other bun and serve immediately.
Notes
- For best results, use 80/20 ground beef for optimal juiciness and flavor.
- Press the patties firmly but avoid overhandling the meat to keep them tender.
- Customize toppings to your preference—add bacon, sautéed mushrooms, or jalapeños for extra flavor.
- If you don’t have a grill, a heavy cast iron skillet works equally well for smashing the burgers.
- Secret sauce can be made ahead and stored in the refrigerator for up to 3 days.
