Bangkok’s Double Trucker Burger: A Smashburger That Redefines Deliciousness

The Best Burger I Ever Tasted Was in Bangkok

It may sound surprising, but one of the greatest burgers I’ve ever enjoyed wasn’t in cities like L.A., New York, or Tokyo — it was in Bangkok, Thailand. Nestled in a modest establishment named Barney’s Burger Joint, I encountered what could be the most perfectly crafted smashburger: The Double Trucker Burger.

The Key: A Flawless Patty Smash

Initially, it appears quite basic — simply American cheese, bacon, caramelized onions, and common condiments. However, this simplicity is misleading. The standout feature is the patties, which are thin and aggressively smashed disks of finely ground beef that are both crispy and juicy, bursting with flavor.

While many smashburgers begin with meatballs pressed down on a griddle, Barney’s approach is unique. They pre-form their patties, ensuring consistency and an ideal balance between crust and juiciness. Utilizing a sturdy flat spatula, they smash from the center outwards, applying firm pressure, resulting in a thin, evenly browned patty with crispy edges — the essence of an excellent smashburger — while keeping the center moist.

It’s All in the Details

Caramelized onions contribute a deep sweetness that complements the salty, smoky bacon. American cheese melts into the crevices of the smashed patties, acting as a creamy binder. Pickles, mustard, and diced onions add a tangy punch, while wrapping the burger in foil enhances steam, melding the flavors into one delicious, cohesive bite.

Making the Caramelized Onions

Cooking the Burger

Cook bacon until crispy; then drain on paper towels. Toast burger buns with a bit of butter until golden. Shape the ground beef into 100 g discs. In a hot cast iron pan, add a little oil. Place the patties, season with salt and pepper, and smash from the center outward with a heavy spatula.

Add a squirt of mustard on each patty. Cook until the bottom turns deep brown, flip, and add another squirt of mustard. Top with 2 slices of American cheese, then stack two patties together, covering briefly to melt the cheese.
