Herb-Infused Roasted Potatoes

Why This Herb-Infused Roasted Potatoes Works

In the hot oven, the cut sides of the potatoes sit right against the pan, so those spots dry out a bit and start to brown. As they brown, the outside firms up and turns crisp, while the inside of each piece stays soft and fluffy. The high heat does this pretty quickly, so the potatoes cook through without drying out all the way.

Olive oil coats every piece, so the herbs and seasonings stick instead of sliding off. During roasting, the oil also keeps the surface from burning and lets the potatoes brown in spots instead of just steaming. When the potatoes are stirred halfway, new sides touch the hot pan, so more edges get that golden crust.

Fresh rosemary and thyme sit in the warm oil on the potatoes and slowly spread their taste over the whole pan. At the end, lemon zest goes on while the potatoes are still hot, so the tiny bits of peel warm up and their sharp, bright taste stands out against the rich, roasted potatoes.

Mistakes To Avoid

Crowding the potatoes on the baking sheet keeps steam trapped around them. Instead of the edges drying out and crisping, the pieces stay pale and soft, and the bottoms can turn soggy where they touch the pan.

Cutting the potatoes into very different sizes causes uneven cooking. Smaller pieces turn hard and dry before the centers of the bigger chunks are soft, so the tray ends up with some burnt bits and some undercooked, chalky pieces.

Roasting at a lower temperature than 425°F makes the potatoes cook through but not brown properly. The outsides stay soft and a bit leathery instead of getting that firm, crisp surface that contrasts with the fluffy middle.

Skipping the toss halfway through roasting leaves one side of each potato piece stuck against the hot pan the whole time. That side can get too dark or even burn while the top side never gets much color or texture.

Adding the lemon zest before roasting instead of at the end causes it to dry out and scorch on the hot pan. The tiny burned specks stick to the potatoes and leave a bitter, harsh edge instead of a fresh, bright finish.
