Tips & Notes

Pro tips

Divide beef into two 4 oz portions before cooking; don't overwork the meat or it will be dense.
Press the patties down hard with a spatula immediately after they hit the hot griddle to create maximum crust; hold for 2–3 seconds, then release.
Cook the diced onions directly into each patty while smashing to lock in onion flavor and prevent moisture loss.
Toast the brioche bun in melted butter on the griddle or pan for texture contrast and to prevent sogginess from sauces.

Substitutions

American cheese → cheddar or Swiss (note: flavor will shift from classic diner-style to more robust)
Brioche bun → potato bun or standard hamburger bun (note: brioche toasts better and absorbs less moisture)
Special sauce → mayo-ketchup blend or burger sauce from scratch (note: adjust ratios to taste)

Storage & make-ahead

Best served fresh off the griddle. Leftover cooked patties can be refrigerated up to 3 days and reheated on a griddle or skillet; assemble fresh buns and toppings just before serving.

Equipment

Common Questions

Why do you smash the burger patties thin?

Smashing creates more surface area for crust development and helps the onions embed into the meat, adding flavor. Thin patties also cook quickly and evenly.

What temperature should the griddle be?

Use a very hot griddle or flat-top. It should sizzle immediately when the beef hits the surface so the patties form a crust within seconds.

Can I use a regular burger bun instead of brioche?

Yes. Brioche is preferred for its buttery richness and toasting ability, but a standard burger bun works fine—just toast it lightly in the melted butter.
