  • 1 clove garlic, grated
  • ¼ teaspoon salt
  • ⅛ teaspoon black pepper
• Sautéed Mushrooms:
  • 3 tablespoons unsalted butter
  • 1 (16-ounce) package sliced cremini mushrooms
  • 5 sprigs thyme
  • ½ teaspoon salt
  • 1 teaspoon Worcestershire sauce
• Smash Burger Patties:
  • 1 ¼ pounds ground chuck
  • ¼ teaspoon garlic powder
  • ¼ teaspoon onion powder
  • ¼ teaspoon paprika
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • 4 slices Swiss cheese
  • 4 kaiser rolls, split and toasted

Preparation Steps

1. Prepare the Truffle Mayo:

Whisk together mayonnaise, lemon juice, truffle oil, parsley, garlic, salt, and black pepper in a small bowl. Set aside.

2. Sauté the Mushrooms:

Melt butter in a large cast-iron skillet over medium-high heat. Stir in mushrooms and thyme sprigs and cook, stirring occasionally, until mushrooms are golden brown and tender (about 10 minutes). Remove thyme sprigs, season with salt and Worcestershire sauce, and transfer mushrooms to a bowl. Keep warm.

3. Make the Burger Rub:

In a small bowl, mix garlic powder, onion powder, paprika, salt, and black pepper.

4. Form and Cook the Patties:

• Divide ground chuck into 4 equal portions and shape them into balls.
• Heat the same skillet over medium-high heat.
• Add meat portions to the dry skillet and firmly press down with a flat spatula or grill press into 4½-inch patties.
• Sprinkle each patty evenly with the rub and cook for 2 minutes per side.
• Top patties with Swiss cheese and cook for 30 more seconds, allowing the cheese to melt.

5. Assemble the Burgers:

• Spread truffle mayo on both bun tops and bottoms.
• Place smash burger patties on buns.
• Top with sautéed mushrooms.
• Serve hot and enjoy!

Pro Tips

• Get a Good Sear: Press the patties firmly into the pan to maximize caramelization.
• Keep It Hot: Use a cast-iron skillet for the best smash burger results.
• Toast the Buns: A lightly toasted bun prevents sogginess and adds an extra layer of texture.
• Let the Meat Rest: After cooking, let patties rest for a minute before assembling to keep juices locked in.
