Ingredients

  • One pound of ground beef (80/20 blend recommended): brings juiciness and flavor crucial for the perfect smash burger
  • Salt and freshly ground black pepper: used to season the patty enhancing the beef’s natural taste
  • Four ounces cooked lobster meat: chopped to add delicate sweetness and a bit of seafood luxury
  • One tablespoon butter: for warming the lobster which adds richness and helps meld the flavors
  • Two slices of sharp cheddar cheese: chosen for its meltability and sharp tang
  • One brioche bun: toasted to give the burger a slightly sweet, tender bite with a sturdy texture that holds everything together
  • One tablespoon mayonnaise: adds creamy moisture
  • One teaspoon Dijon mustard: optional for a subtle tang and complexity
  • Two crisp leaves of romaine or iceberg lettuce: for freshness and crunch
  • One or two slices of ripe tomato: contribute juiciness and balance to the richness
  • Optional garlic aioli or spicy remoulade: to drizzle on top for a little extra flavor kick

Step-by-Step Instructions

Smash That Patty:
Start by loosely forming the ground beef into a ball without overworking it. Heat a skillet over medium-high heat. Place the beef ball on the hot surface and press it down firmly with a spatula until it’s roughly a quarter inch thick. Season with salt and pepper. Cook undisturbed for 2 to 3 minutes until the edges are deeply browned and crispy. Flip carefully and immediately add the cheddar slices on top. Cover the pan to let the cheese melt perfectly while the second side finishes cooking, about 2 more minutes.
Warm the Lobster in Butter:
While the burger finishes, melt the butter in a separate small skillet over medium-low heat. Add the chopped lobster and toss gently just until the lobster is warmed through, no more than 2 minutes. This step infuses the seafood with a buttery richness without drying it out.
Toast the Bun:
Place the brioche bun cut side down on a dry skillet or griddle over medium heat. Toast until golden brown and slightly crisp. This prevents sogginess when you add sauces and juicy ingredients.
Stack the Burger:
Spread mayonnaise and optional Dijon mustard evenly on the insides of the toasted bun. Place the cheesy smash patty on the bottom bun. Top with warm lobster, followed by the lettuce leaves and tomato slices. Drizzle your choice of garlic aioli or spicy remoulade over the top layer before closing the sandwich.
Serve Immediately:
Serve the burger hot with crispy fries or chips on the side. Make sure to eat quickly to enjoy the melty cheese and buttery lobster at their best.

Storage Tips

This burger is definitely best fresh but if you have leftovers, store components separately. Keep the lobster refrigerated in an airtight container for up to two days. The burger patties reheat best in a skillet over medium-low heat to maintain crisp edges while melting cheese again. Toast buns just before serving.

Ingredient Substitutions

You can swap cheddar for gouda or fontina for a creamier melt. For the lobster, cooked crab meat works well if you want a different seafood vibe. Use whole wheat or potato buns as healthier or flavor-forward alternatives.

Serving Suggestions

Serve with classic fries, sweet potato fries, or even a crisp green salad for a lighter balance. A cold lager or a citrusy white wine pairs beautifully with the rich flavors.

Cultural Context

Smash burgers originated in American diner culture known for crispy edges and juicy centers. Adding lobster turns this humble recipe into an indulgent coastal treat blending comfort food with seafood luxury.
