4 Reasons Not to Substitute Canned Tuna for Fresh in a Burger

Fresh tuna holds together when seared Raw tuna has enough structure to form a patty that stays intact during cooking, similar to ground beef.

Canned tuna is already cooked and flaky It falls apart easily in a pan, resulting in a crumbly mess that won’t hold its shape without a binder.

Adding binders changes the dish entirely Eggs, breadcrumbs, or mayo turn it into a tuna cake or croquette, not a burger—the texture becomes soft and delicate, not firm and meaty.

Stick with the right ingredient for the job For a quick, cheap tuna sandwich, make tuna salad. For a burger, use fresh tuna or ground beef.
