Hmmm, I've never done it with boneless breasts, but I don't want to discourage you from trying my
favorite, and I'm sure it would be easy to serve and eat with boneless chicken.
First, I'd recommend making some homemade chicken stock. The canned stuff won't make such a good sauce without bone-in chicken pieces adding their share. Second, if possible, use breasts with the skin still on to keep them moist, and be very vigilant while braising them so they don't boil. You just want to poach them. Maybe even use a lower oven temperature.
I once had a request for all-white meat for this recipe. I talked them out of boneless breasts and instead bought a number of those tiny Kosher chickens at Trader Joe's. I cut them up leaving the wings attached to the breasts and they made small elegant servings. (I cooked the dark meat too and saved it for later). But that's a lot of work and small chickens are hard to find.
Good luck!
