Smashed. Stacked. Sauced.
No frozen pucks. No sad buns. Just 90g of beef smashed screaming-hot onto cast iron, stacked with intent, and drowned in sauce from our lab. Karachi, you're welcome.
Anatomy of a stack
Watch it assemble itself. Every layer has a job — structure, moisture, crunch, acid, heat. That's not a burger, that's engineering.
Smash-seared patty
90g chuck pressed hard onto 260°C cast iron for a crust you can hear.
Flame-finished crust
A final torch pass caramelises the edges — pure campfire aroma.
Lab-made sauces

Garden-cut crunch

Karachi is talking
"The Double Trouble ended my loyalty to every other burger in Karachi. The crust on that patty is criminal."
"Ordered the Blaze Reaper on a dare. Sweated through it, ordered two more the next day. No regrets."
"25 minutes from phone call to door and the fries were still crisp. Whatever lab magic this is — keep it going."

served with love
STACK'D Lab began with a simple grudge: Karachi deserved a burger that wasn't an afterthought. No microwave patties, no watery sauces — just beef, fire, and a stubborn obsession with the perfect stack.

Griddle live since day one
The lab rulebook
Fresh, never frozen
Beef arrives from the butcher every morning. If it ever touches a freezer, it doesn't touch our griddle.
The sauce lab
Eleven signature sauces, 40+ failed prototypes. The famous orange lava took 9 months to perfect.
The 25-minute promise
From your tap to your door while the cheese is still doing its slow thing. Or the shake is on us.
Honest & local
Karachi suppliers, Karachi crew, Karachi attitude. We name our farmers on the kitchen wall.
From cart to cult
Two burners, one dream
We started as a tiny food cart outside DHA Phase 1 with a borrowed griddle and a sauce notebook.
The Lab opens
The queue got longer than the street. So we signed a lease, painted everything charcoal, and lit the big fire.
18,000 burgers later
Karachi decided we were a thing. Best Smash Burger city-wide, two years running.
Bigger lab, same fire
Second branch on the way. Same recipe, same rulebook: smash it fresh or don't serve it.
