Is the word recomendo the same in Brazilian and European Portuguese?

Yes

The spelling, meaning, and grammatical function of "recomendo" are identical in both Brazilian and Continental Portuguese. The only difference lies in pronunciation.

In Brazilian Portuguese, the vowels are generally more open and clearly articulated. When saying "recomendo," the unstressed "e" is clearly audible. In Continental Portuguese, vowels are often "reduced" or "closed." This means the unstressed "e" might sound much shorter, closer to an "i," or even almost disappear, resulting in a more swallowed sound.
