If you crave a classic smash burger after midnight, Stack is open late and slinging exactly what you want: crispy-edged patties, gooey cheese, and soft buns. Multiple locations mean you're rarely too far from your next burger fix.
Stack sticks to doing one thing extremely well: smash burgers with insanely crispy lace edges and the perfect cheese melt, no fussy toppings or chefly gimmicks. Unlike chain burger spots, Stack keeps ingredients super simple and consistent, and their late-night hours outpace most indie burger joints.
Toronto's smash burger scene has grown substantially — the technique (pressing a ball of 80/20 beef flat against a very hot griddle surface at the moment of cooking, creating a wide, lacy-edged patty with maximum surface caramelization) produces burgers fundamentally different from the thick-formed patties of previous fast-casual generations. The double smash burger (two thin patties, two slices of American cheese, melted through the stack) achieves a cheese-to-meat ratio that a thick patty cannot: the cheese becomes part of the structural integrity rather than an accompaniment.
The critical technique in smash burger production is griddle temperature and pressing force: the griddle must be very hot (350-400°C surface temperature) and the press must be immediate and firm (within seconds of the beef contacting the surface) to achieve the Maillard reaction on the widest possible surface area. The result is a patty with a caramelized, slightly crispy edge and a very thin profile that stacks with cheese for maximum richness per bite.
The special sauce is the condiment that holds the smash burger together — typically a combination of mayonnaise, ketchup, mustard, relish, and sometimes hot sauce or pickle brine, applied to both bun faces in quantities that seem excessive until the first bite establishes that it was exactly right. The fries at a serious smash burger operation should be crispy (either double-fried or cooked from a quality potato without ice crystal moisture) and salty enough to require no addition.
Toronto's smash burger operations range from converted food trucks to dedicated fast-casual spots to basement burger bars in the Entertainment District. Late-night availability is part of the format's appeal: the griddle kitchen is fast, the food holds briefly without losing quality, and the price is accessible for late-night budget constraints.
A smash burger is pressed thin against a very hot griddle at the moment of cooking, creating maximum surface contact and Maillard reaction (caramelization). The result is a thin, lacy-edged patty with a crispy exterior and juicy interior — different from the thick formed patties of most burgers.
Double patty (two thin smash patties) with American cheese melted through the stack, special sauce on both bun faces, pickles, and fresh onion. The double provides the right cheese-to-meat ratio. Add crispy fries.
Smash burgers are among the best late-night food options — the griddle kitchen is fast, the food is satisfying and accessible in price, and the rich, saucy nature of a double smash burger suits late-night appetite perfectly.
