Ingredients
  

The Burger & Buns
  • 4 large bakery croissants sliced in half horizontally
  • 1 lb ground beef (80/20) kept cold, divided into 4 balls
  • 4-8 slices American or cheddar cheese
  • 1 tbsp kosher salt for seasoning
  • 1 tsp black pepper for seasoning
Garlic Herb Glaze
  • 2 tbsp unsalted butter melted
  • 1 clove garlic minced
  • 1 tbsp fresh parsley finely chopped
Burger Sauce & Toppings
  • 0.33 cup mayonnaise
  • 2 tbsp ketchup
  • 1 tbsp sweet pickle relish
  • 0.5 tsp garlic powder
  • 4 leaves butter lettuce washed and dried
  • 4 thick slices tomato

Equipment

  • Cast Iron Skillet or Griddle
  • Heavy burger press or stiff metal spatula
  • Parchment paper
  • Serrated bread knife

Method
 

  1. Mix mayonnaise, ketchup, relish, and garlic powder to make the burger sauce. Set aside in the fridge.
  2. Mix melted butter, minced garlic, and parsley to create the croissant glaze.
  3. Slice croissants in half, lightly toast the cut sides, and brush the top halves with the garlic herb glaze.
  4. Divide cold beef into loose 4oz balls. Do not season yet.
  5. Heat a dry cast-iron skillet over high heat until smoking. Place meat balls in the pan, cover with a small piece of parchment paper, and smash completely flat using a heavy spatula.
  6. Remove parchment, season heavily with salt and pepper. Cook for 2-3 minutes until edges are dark, crispy, and lacy.
  7. Scrape under the patty firmly to preserve the crust, flip, and immediately top with cheese. Cook 1 more minute until melted.
  8. Assemble: Spread burger sauce on the bottom croissant, add lettuce and tomato, top with the cheesy smash patty, and cap with the garlic-buttered croissant top. Serve immediately.

Notes

Using 80/20 ground beef is essential for the fat content needed to create the crispy, lacy edges of a proper smash burger. Do not use lean beef.
