Garlic Hasselback Potatoes with Herbed Sour Cream

This was one of our side dishes for our Valentine's Day celebratory dinner at home. I thought they were a chi-chi version of baked potatoes but they weren't difficult at all to make. I made the herbed sour cream ahead of time so that the flavors had more time to marry. As advised in some of the reviews I read, I added shallots to the olive oil-garlic mixture with which I basted the potatoes. This recipe is perfect for company since it's easy to make but has a great gourmet flair!
