My wife is a dual American-Irish citizen. Our strategy for flights to and from the EU is:
On flights from US -> EU: check in for the flight on the US side with her US passport; use Irish passport to clear immigration on the EU side
On flights from EU -> US: check in for the flight on the EU side with her US passport; use Irish passport to clear exit immigration on the EU side; use US passport to clear immigration on the US side

It's possible TIMATIC will barf up something about no return ticket if you check in with your US passport. If that happens, just check in with your Dutch passport.
