Crispy Garlic Parmesan Potatoes: The Ultimate One-Pan Side Dish Step-by-step instructions

Before you start

Before beginning, ensure the oven is fully preheated to the correct temperature. A cold oven will cause the potatoes to steam and lose their potential for a crispy crust. Scrub the potatoes thoroughly under cold running water to remove any dirt or debris, then dry them completely using a clean kitchen towel.

Moisture on the surface of the potatoes will inhibit the browning process. Have your baking sheet ready and clear your workspace so that you can easily toss the potatoes with the seasonings before arranging them on the pan.

Instructions

Seasoning and Preparation

1. 1Prepare the potatoes
   Preheat the oven to 400°F (200°C). Wash the baby potatoes thoroughly and cut them in half. Place the halved potatoes into a large mixing bowl. Add the minced garlic, dried herbs, and toss everything together until the potatoes are evenly coated with the seasonings.
   Look for Potatoes should be evenly coated in spices.
   Tip Dry the potatoes well after washing to ensure a crispy skin.

The potatoes should be thoroughly coated in the seasoning mixture. Every surface of the potato should appear dry and coated, and the minced garlic and herbs should be evenly distributed. Ensure that the bowl is large enough to toss the potatoes without spilling, allowing for an even application of the herbs before transferring them to the baking sheet.

Roasting and Crisping

2. 2Roast until golden
   Spread the seasoned potatoes in a single layer on a large baking sheet pan, cut-side down. Roast in the preheated oven for 30 minutes. Remove the pan from the oven and sprinkle the grated parmesan cheese over the potatoes. Return to the oven and roast for an additional 10 minutes until the cheese is melted and the potatoes are golden brown and crispy.
   Look for Potatoes should be golden brown and the cheese bubbly.
   Tip Placing potatoes cut-side down creates the best golden crust.

The potatoes should be arranged in a single layer, cut-side down, to ensure maximum contact with the baking sheet. After 30 minutes, the potatoes should have developed a light golden color. Once the parmesan is added, the final 10 minutes of roasting should yield a deep, dark golden hue and a crispy, bubbly texture that indicates the potatoes are perfectly prepared.

Resting and Serving

3. 3Serve warm
   Remove the baking sheet from the oven and let the potatoes rest for 5 minutes. Use a metal spatula to transfer the crispy potatoes to a serving plate. Serve immediately while they are hot and maintain their signature crunch.
   Look for Potatoes should be steaming and crispy to the touch.
   Tip Do not cover the potatoes after roasting, as steam will soften the crust.

The potatoes should rest for 5 minutes after being removed from the oven. This allows the internal moisture to redistribute and the crust to set properly, ensuring that the potatoes remain crispy when moved to the serving plate.

The final result should be a beautiful, steaming pile of golden potatoes that are ready to be served as an inviting and flavorful side dish.

Common mistakes

A common mistake is overcrowding the baking sheet, which prevents proper air circulation and causes the potatoes to steam rather than roast. Always ensure the potatoes are in a single layer with space between them.

Another error is failing to dry the potatoes after washing; excess water creates steam, which is the enemy of a crispy crust. Finally, adding the parmesan cheese too early can lead to the cheese burning before the potatoes are fully cooked through, resulting in a bitter flavor instead of a nutty, savory finish.

How to tell it’s done

The potatoes are done when they are golden brown, fork-tender, and have developed a distinct, audible crunch on the exterior. The parmesan cheese should be melted and lightly browned around the edges.

When pierced with a fork, the center of the potato should be soft and fluffy, offering no resistance. If the potatoes are still firm in the middle, continue roasting for an additional 5 minutes, checking frequently to ensure the cheese does not darken too quickly or burn.
