Yummy!! I just made this and completely loved it! I was also unsure about how it would turn out, but I definitely recommend it. I did have to make a variation, I did not have enough yukons so I made the dish with half yukons and half sweet potatoes. I love sweet so I loved the sweet potatoes mixed in, I don't think I would ever make it with just sweet potatoes though. The part that was made with just yukons was also amazing, this recipe is certainly a keeper. Even better that it has make ahead instructions! And I have to say, I just reheated and polished off the remainder of the leftovers...just as yummy the second night as the first. Enjoy and thanks for posting!
Oh man, my mom makes this and it is the best! I was just looking around to see if it was already posted, cause it is a fantastic recipe! I love the savory-sweet combo, and the thyme is just perfect. Can't say enough about it! A must try!
