Step-by-Step Instructions
Step 1: Prepare the Secret Sauce
- In a small bowl, combine mayonnaise, ketchup, mustard, relish, vinegar, smoked paprika, and garlic powder.
- Mix well until smooth and creamy.
- Cover and refrigerate while you prepare the burgers.
Step 2: Toast the Brioche Buns
- Heat a large skillet or griddle over medium heat.

Step 3: Smash the Burger Patties
- Divide the ground beef into 4 equal portions (about 4 oz each). Do not overwork the meat!
- Heat a cast-iron skillet or griddle over high heat until smoking hot.
- Place one portion of beef on the skillet and immediately smash it down using a metal spatula or burger press.
- Pro Tip: Use parchment paper between the spatula and meat to prevent sticking.
- Season with salt, black pepper, and garlic powder.
- Let it cook undisturbed for about 1-2 minutes until crispy and caramelized.

- Repeat for the remaining patties.
Step 4: Assemble the Ultimate Smash Burger
- Spread secret sauce generously on the toasted buns.
- Add lettuce and tomato slices to the bottom bun.

- Finish with the top bun and press down slightly to bring everything together.
Step 5: Serve & Enjoy!
