Savory Garlic Herb Potatoes

Why This Savory Garlic Herb Potatoes Works

In the oven, the potato cubes dry out a little on the outside while the inside softens. The hot air hits all sides because they are spread in a single layer, so the edges start to brown and crisp up instead of steaming. As they roast, the starch near the surface firms up, which gives that crunchy outside, while the centers stay fluffy.

During roasting, the olive oil coats each piece, so the garlic and herbs stick to the potatoes instead of falling off on the pan. The oil also keeps the outside from drying out too hard, so the crust stays crisp but not tough. Flipping the potatoes halfway lets more sides touch the hot pan and brown.

Right after they come out, the hot potatoes melt the Parmesan a bit. The cheese clings to the rough, crispy surface and forms little salty, toasty spots as it cools. By the time they reach the table, each cube has a soft middle, a crunchy shell, and a thin layer of herbs, garlic, and cheese holding on.

Mistakes To Avoid

Cutting the potatoes into very different sizes means some pieces cook much faster than others. Smaller cubes turn hard and dry by the time the bigger chunks finally soften, so the tray ends up with a mix of burnt bits and undercooked centers.

Crowding the baking sheet is another common problem. When the potatoes sit on top of each other instead of in a single layer, they steam instead of roast, so they come out soft and pale instead of crisp and browned.

Adding the Parmesan before baking instead of at the end causes trouble. The cheese melts and then burns on the hot pan long before the potatoes are tender, leaving a bitter, hard crust stuck to the tray while the potatoes stay unevenly cooked.

Using too little oil keeps the seasonings from sticking and leaves the surface of the potatoes dry. In the oven, those dry spots don’t brown well and can turn leathery instead of getting a thin, crisp outer layer.
