Absolutely love it! This is the best sweet potato dish I've ever had. I like the mix of sweet and regular potatoes to cut down on heavy sweet potato taste, and the garlic and rosemary are perfect coompliments. We couldn't stop eating them. I'll make this one all the time, and have already decided it will be a yearly addition to our Thanksgiving table. I made them using soy milk, Smart Balance margarine, and soy parmesan with excellent results. A thousand thanks for sharing this little gem!

Very good. I cheated and used Idahoan garlic flavored instant potatoes with great results.

This is fantastic! I really like the mix of the two potatoes. I cheated on this recipe and simply made mashed potatoes, adding rosemary, garlic powder and parmesan cheese to the potato mixture. I didn't bake it in the oven as I didn't think that was necessary. This is my new favourite sweet potato recipe!
