Is it incorrect to say "recommend me"?

In this case, usage by native speakers is the most reliable guide. Here’s how I’d break it down based on what I observe: * **“Recommend me similar stuff”** — correct, but informal * **“Recommend similar stuff to me”** — correct and neutral * **“Recommend to me similar stuff”** — *highly* unnatural * **“Recommend similar stuff”** — correct Grammatically, “me” is the **indirect object**, and “similar stuff” is the **direct object**. *Recommend* requires a direct object, while the indirect object is optional.

It’s usually “recommend a movie to me”. The most common use without “to” would be “he recommended me for the job”

"Recommend similar stuff to me." sounds best. Recommend me... means "me" is what is recommended.  "Could you recommend me to your beautiful single friend?" "I need a job. Do you think you could recommend me to your boss?"

It's "incorrect" but fairly common. It is more correct to say, "Please could you recommend something similar". Natives might say "Can you recommend me similar stuff", but other natives would think they were of low intelligence because of their use of that phrase. Said natives may say "Can you suggest anything similar", or variations thereupon. "Suggest" is a useful word. > Can you suggest any similar books/movies? You *could* say, "do you have any recommendations?" in the context of a discussion about movies or something.

“recommend (me) similar stuff” is fine, but it’s more polite to phrase it as a question rather than a command. “could you recommend me similar stuff?” “would you recommend some similar stuff?” i don’t think anyone would particularly mind either way but that’s how i hear that kind of thing phrased the most often

It would be more colloquial, so in speech yes, but in formal writing you wouldn’t see it.  As for your second question, I would personally say the first in 2. but it all depends on the speaker.

"Recommend me similar stuff." is fine. "He recommended me to do it." is, however, an error. It should be "He recommended (that) I do it."

"Recommend me similar stuff." is fine. Something like that "He recommended me to do it." is usually an error. It should be "He recommended (that) I do it." It is correct if it's saying someone asked for someone who could do it and he recommended you to that person.

What do you recommend? Do you have any recommendations? I would love some suggestions for good movies to watch. I need recommendations for something to read. Can you suggest something good?

Can you recommend me something to watch?

"Recommend similar stuff to me" is the most correct. You are asking for the person to recommend similar stuff to you, not asking the person to recommend *you* (like recommend you for a job or something). In casual speech though, "recommend me a movie" or "recommend me some good songs" is not a big deal and would be understood perfectly.

Recommend me is not correct unless you are saying "recommend me for the job..." or "recommend me to him..." In the sentence structure where you are requesting (demanding) that someone give a recommendation, it is "recommend *something*" So the noun after recommend it the thing being recommended, not the person to whom the recommendation it is going.

I definitely consider it wrong, but younger, American people seem to do it, so maybe it's becoming acceptable there. I would only correct them if they were on an English language or grammar sub.

"Recommend me" is not really grammatically correct in this context, but would absolutely be understood, and I could definitely see myself or some other native speakers making this same 'mistake' when talking or texting casually.

It’s not incorrect, but it is less common. > He recommended me a book. ✅ > He recommended a book to me. ✅ (better) > He recommended me to leave. ✅ > He recommended that I leave. ✅ (better, *much* more common) This is a matter of usage rather than grammar.

“Recommend me a book,” is grammatically correct, same as “write me a story” or “sing me a song” It’s slightly impolite though, as it’s a command. It would be more common in casual speech to say something like “Can you recommend any good books?”

As a native speaker, I feel like it would be natural enough to hear someone say 'Recomend me some music?', although it would imply a more casual tone.  The main time I'd hear the term 'recommend me' used is, for example, in relation to a job. Let's say your friend works at a company and the company is thinking of hiring someone for a job. You might ask your friend 'could you reccomend me for the job?'. In this situation, the recommendation isn't being given you you; you *are* the thing being recommended.  'Could you reccomend some music to me?' would be a less casual more neutral way of asking. 

As a native speaker, when you start a sentence with 'recommend me', then I expect you to ask me to recommend you to someone. For example, I would expect you to ask me to recommend you for a job, a position on a team, or something like that. When you say "recommend me" it has a different usage from 'recommend something to me'.
