Best Answer

A hamburger's main ingredient is ground beef, which has no starch. However, there are many methods to prepare the meat prior to cooking it as a hamburger. This can include use of breadcrumbs as a filler, and if these are not used, there most likely is no starch in the hamburger.

Does hamburger have starch in it?

A hamburger may or may not have starch in it. A hamburger starts out as ground beef. That is the basic patty. If you purchase it that way and cook it yourself, it does not contain starch. A number of companies add soy meal (or other products) to ground beef to make hamburger patties. In that case a hamburger contains starch. If you eat your hamburger in a bun, or add garnishes, or cheese, or a number of other products, you added starch. So, a hamburger may or may not have starch.
