Love this recipe!
I have no trouble with an overpowering garlic taste. I don't know what I do differently. I just follow the recipe and cook in my slow cooker. This is one of my go to recipes and I use it for entertaining as well. I only get raves. My only complaint is that the chicken gets a little dry if I leave it in the cooker too long. I also double the carrots.
I agree with the person who referenced the overpowering garlic flavor. It was especially bad when I reheated the leftovers. This was edible and tasted hearty, but I would never make it again.
