Sp_blitzcache will give you this information.
Have a look: https://www.brentozar.com/blitzcache/
In the past, this has helped me find queries running thousands of times/minute that were having parameter sniffing issues, meaning the same query was being recompiled each time.

Plan A: Turn on the "general log" and use pt-query-digest to analyze the log.
Plan B: Set long_query_time = 0 and turn on the slowlog. Then use pt-query-digest to analyze the log.
Caution: In either case, disk will fill up fast.
With the slowlog you get a lot of other information -- useful if you are concerned about what is bogging down the system. That is a different question than 'frequency'; it is frequency * avg execution time.
