Recommend Doing vs. Recommend To Do
“Recommend + -ing” is a standard way to advise an action, and a that-clause is another. A bare direct “recommend to do” is not the same pattern, although Oxford also documents “recommend + object + to-infinitive,” so the distinction needs an object-pattern caveat.
For a general action, use “recommend doing” or a that-clause. Do not use bare direct “recommend to do” as the equivalent, but note that Oxford documents “recommend + object + to-infinitive.”
Key details
Further guidance
Clause Pattern
A that-clause is also standard, such as “recommend that you check.”
Direct Boundary
Bare direct “recommend to do” without an object is not the ordinary action-complement pattern documented by these references; use “recommend doing” or a clause for that job.
Ing Pattern
Use recommend + -ing for recommending an action generally, as in “recommend checking.”
Object Infinitive Boundary
Do not turn the rule into a blanket ban on every “recommend … to do” sequence: Oxford documents recommend + object + to-infinitive, such as “recommend you to book.” The object is part of that construction.
