Fingerling Out What to Do with these Potatoes

We found these delicious fingerling potatoes at the market, tiny and golden. But how to cook them?

Since we had plans to put a chicken on to roast, we decided maximizing our use of the oven was a fine idea. After rubbing the little fellows with some olive oil, we put them on a parchment-lined baking sheet and ground on a little salt. Then we topped them with sprigs of rosemary we had growing out back. When the chicken was half-done (after 30 minutes at 450F) we put the potatoes in. At the one-hour mark we took the chicken out to rest, and turned off the oven, leaving these tiny morsels to finish cooking.

They were crispy on the outside, and creamy on the inside, and good all over.
