Maybe you want to try making this one more time. Putting the chicken in a marinade is probably a good idea. But, just reading this recipe gives me a clue as to where the problem is. It rests within these ingredients:
3/4 cup plus 3 tablespoons water, divided
2 tablespoons dried minced onion
2 teaspoons chicken bouillon granules
2 teaspoons chili powder
1/2 teaspoon dried tarragon
1/2 teaspoon Italian seasoning
1/4 teaspoon garlic powder
For me, the problem starts with chicken bullion granules. Scrap that. All you will get is a weak, watery, very salty liquid. Get some good old chicken broth, salt free if you like, and begin with that. Add REAL onions and REAL garlic. That is a must. Then, don't be afraid to use seasonings. The chili powder seems OK, but I would use paprika instead, or maybe some of each. Give it some tarragon. That is great stuff. Italian seasoning is OK, but 1/2 t of each isn't enough. Kick that up to a T of each.
Now ... doesn't that seem better already? And, if that isn't enough, throw in a splash or two of dry white wine and see what happens.
I am going to make this tonight. I will start by firing up the grill, and, with it really hot, I will sear the chicken quickly over the fire so that the outside seals up. Then, it will go into the crock pot to finish cooking.
OK ... it takes a few minutes more, but I expect to get an entirely different dish than the one that you guys didn't like. Give it a go ...
