Learn Hardcore Spanish (Spain): Me gusta el pan casero.

In Spanish, gustar doesn’t work like “to like” in English.
Literally, me gusta el pan casero is closer to “homemade bread pleases me”.

Me = to me (indirect object pronoun)
gusta = pleases (3rd person singular)
el pan casero = the homemade bread (the thing that pleases)

So the subject of the verb is el pan casero, not yo.
That’s why it’s me gusta (it pleases me) instead of yo gusto (I please).

What exactly is me here? Is it like “me” in English?

Me here is an indirect object pronoun, meaning “to me”.

Spanish indirect object pronouns:

me – to me
te – to you (informal)
le – to him / to her / to you (formal)
nos – to us
os – to you (plural, Spain)
les – to them / to you (plural, Latin America)

With gustar, you must use this pronoun. You cannot say just “gusta el pan casero” to mean “I like homemade bread”; you need me: me gusta el pan casero.
