Garlic Herb Crusted Roasted Potatoes

Why This Garlic Herb Crusted Roasted Potatoes Works

In the hot oven, the cut sides of the baby potatoes sit flat on the pan, so they stay in one place long enough to brown. As they roast, the outside dries out a bit and firms up, while the inside softens and turns fluffy. The high heat lets the edges go golden and crisp instead of steaming and staying pale.

While everything cooks, the olive oil coats each potato piece so the garlic and dried herbs stick to the surface. The oil also keeps the potatoes from drying out too much, so the centers stay tender even as the outside crisps. Salt and pepper sink into the cut sides, so the seasoning doesn’t just sit on top.

After a few minutes in the oven, the grated Parmesan starts to melt onto the hot potatoes. Then it dries and hardens into a thin, crunchy layer. That cheese crust clings to the rough, browned surface and adds another crispy coating on top of the already crisp potatoes.

Mistakes To Avoid

Crowding the potatoes on the baking sheet makes them steam instead of roast. The trapped moisture keeps the edges from drying out, so the potatoes stay soft and pale instead of getting a crisp crust.

Putting the potatoes in the oven while they are still wet from washing leaves water on the surface that has to evaporate first. This slows down browning and can make the herb coating slide off, so the crust ends up patchy and weak.

Adding the Parmesan at the start of roasting causes it to burn before the potatoes are tender. The cheese turns dark and bitter and forms a hard layer, while the potatoes underneath can still be a bit firm.

Cutting the potatoes into very uneven sizes leads to mixed results on the same tray. Smaller pieces dry out and get tough by the time the larger chunks finally cook through, so the texture jumps from mushy to underdone.
