Smash Burger Alfresco

This vibrant alfresco smash burger recipe brings the classic American diner experience to your garden grill. By pressing the minced beef thinly against a scorching cast-iron surface, you create a deeply savoury crust that locks in moisture while providing a satisfying crunch. The addition of a tangy, smoky special sauce made with chipotles in adobo cuts through the richness of the beef, creating a perfectly balanced outdoor feast.

Designed as a high-protein option for summer entertaining, these burgers are ideal for those who appreciate quality ingredients and bold flavours. Serving the patties in soft potato rolls with crisp iceberg lettuce and sharp white onions ensures every bite is full of contrasting textures. Whether you are hosting a weekend barbecue or a quick midweek dinner, this method guarantees professional results every time.

Ingredients for Smash Burger Alfresco

  • 1 cup finely chopped dill pickles

  • 1/2 cup mayonnaise

  • 2 tablespoons ketchup

  • 2 tablespoons sauce from a can of chipotles in adobo

  • 1/2 teaspoons kosher salt, plus more

  • 675g beef mince (20% percent fat)

  • 4 potato rolls

  • 1/2 head of iceberg lettuce, leaves separated, torn into pieces about the size of the buns

  • 1 white onion, very thinly sliced into rings on a mandoline

  • 4 thin tomato slices (optional)

  • 2 tablespoons vegetable oil

  • 8 slices American cheese

Prepare a grill for high heat. Place a cast-iron griddle, flat side up, on grate; heat until very hot, at least 20 minutes.

Mix together pickles, mayonnaise, ketchup, adobo sauce, and 1/2 teaspoons salt in a medium bowl; set special sauce aside.

Divide beef into eight 90g portions (don’t form into patties). Place 4 portions between 2 sheets of parchment paper, spacing 6" apart, and, using a meat mallet or skillet, firmly smash to create thin patties, about 5" across. Transfer to a baking sheet. Repeat with remaining portions and fresh parchment paper.

Wrap all the buns together in a large sheet of foil to make a packet (this will keep buns soft and from getting too toasted on the grill). Place packet on grate and grill, turning once, until buns are warmed through, about 1 minute. Spread sauce over cut sides of buns. Place 3–4 pieces of lettuce on bottom buns and top each with some onion and a tomato slice, if using.

Drizzle oil over griddle and use paper towels to evenly coat surface. The oil needs to be hot; you should see smoke almost instantly. Season patties lightly with salt. Place 4 on griddle, seasoned side down, and season top sides lightly with salt. Cook, undisturbed, until outer edges are brown and undersides are very crisp, about 2 minutes. Flip and place a slice of cheese on top of each patty. Cook until cheese is melted, about 30 seconds. Transfer patties to buns with toppings, stacking 2 patties on each bun. Repeat with remaining 4 patties, scraping off any cheese stuck to griddle in between batches.
