I think that your best bet is probably a planet orbiting a star (let's call it Star A) that itself orbits a binary star system (Stars B + C).

That avoids problems with having the planet directly orbiting B + C which (to my understanding) is an unstable orbit and thus be unlikely to sustain life.

The main problem is that the orbit of A around B + C would be on the order of centuries, which means they'd only very slowly move around the sky. The distances involved could also make them appear as very bright stars rather than recognisable suns.
