The correct sentence is: "My favorite food is hamburgers." In English, when we talk about a type of food in a general sense, we usually use the plural form, unless referring to an uncountable food (like “rice” or “pasta”). Here, "hamburgers" refers to the general category or type of food you enjoy, rather than a specific, single hamburger.

Hi there Wendy! Usually we use the plural form to show our interest in that general category of food. If you say "my favourite food is hamburger" it could refer to one single hamburger or just hamburger meat by itself. So you can say "my favourite food is hamburgers" (pancakes, sandwiches etc). I hope that helps!

“My favorite food is hamburgers” is correct. The singular “to be” verb is used because it relates to the phrase “favorite food” which is singular. Hamburgers, although plural, is here representing a group of objects (many hamburgers). The group (singular) of hamburgers is your favorite.
