Savory Garlic Herb Parmesan Potatoes

Why This Savory Garlic Herb Parmesan Potatoes Works

In the hot oven, the baby potatoes start to steam on the inside while the outside dries out a little. The olive oil coats the skins so they don’t dry out too much, but they still have enough exposed surface to brown. As they roast, the centers soften and turn fluffy, while the outsides firm up and start to crisp where they touch the pan.

After a while, the garlic stuck to the potatoes browns and sticks to the skin instead of burning on the pan. When the Parmesan goes on near the end, it melts, then dries and hardens into a thin, salty crust. That cheese clings to the oiled potato skins and adds more crunch in the spots where it hits the pan.

Once out of the oven, the hot potatoes soak up some of the lemon juice, so the inside tastes bright instead of heavy. Fresh parsley and thyme stay cool and soft on top, so they don’t wilt, and their taste spreads over the warm, crispy potatoes with each bite.

Mistakes To Avoid

Crowding the potatoes on the baking sheet keeps steam trapped around them. Instead of the edges drying out and crisping, the potatoes stay pale and soft, with a boiled texture rather than a roasted one.

Starting with potatoes that are very different in size leads to uneven cooking. Smaller pieces turn hard and dry by the time the bigger ones are finally soft in the center, so the tray ends up with a mix of overdone and underdone potatoes.

Adding the Parmesan at the beginning of roasting causes trouble. The cheese melts and then burns before the potatoes are tender, leaving a bitter, hard crust stuck to the pan while the potatoes underneath are still not fully browned.

Roasting at a much lower temperature than 425°F makes the potatoes dry out before they ever get crisp. The outside wrinkles and toughens while the centers stay a bit firm, and the cheese just melts into a flat layer instead of forming crunchy bits.
