Roast potatoes are a staple side dish in many cuisines, and their crispy exterior and fluffy interior can elevate any meal. However, achieving that perfect crispiness can be a challenge. In this article, we’ll delve into the world of roast potatoes and explore the tips, tricks, and techniques to help you keep them crispy.
Understanding the Science Behind Crispy Roast Potatoes
Before we dive into the tips and tricks, it’s essential to understand the science behind crispy roast potatoes. The key to achieving crispiness lies in the starches and moisture content of the potatoes.
The Role of Starches
Potatoes contain two types of starches: amylose and amylopectin. Amylose is responsible for the potato’s structure and texture, while amylopectin is responsible for its gelatinization. When potatoes are cooked, the heat breaks down the amylose, making the potato soft and fluffy. However, if the potatoes are cooked too long or at too high a temperature, the amylopectin can break down, making the potato mushy and unappetizing.
The Importance of Moisture Content
Moisture content plays a crucial role in achieving crispy roast potatoes. If the potatoes are too moist, they’ll steam instead of roast, resulting in a soft and soggy exterior. On the other hand, if the potatoes are too dry, they’ll become brittle and prone to burning.
Choosing the Right Potatoes
Not all potatoes are created equal when it comes to roast potatoes. Some varieties are better suited for roasting than others.
High-Starch Potatoes
High-starch potatoes, such as Russet or Idaho, are ideal for roasting. They have a higher starch content, which helps them stay crispy on the outside and fluffy on the inside.
Waxy Potatoes
Waxy potatoes, such as Yukon Gold or red potatoes, are not ideal for roasting. They have a lower starch content, which makes them more prone to becoming soft and soggy.
Preparation is Key
Proper preparation is essential for achieving crispy roast potatoes.
Peeling and Cutting
Peel the potatoes and cut them into your desired shape. For crispy roast potatoes, it’s best to cut them into larger chunks or wedges. This allows for more surface area to crisp up.
Soaking
Soaking the potatoes in cold water for at least 30 minutes can help remove excess starch and moisture. After soaking, drain the potatoes and pat them dry with paper towels to remove excess moisture.
Parboiling
Parboiling the potatoes can help remove excess moisture and starch. Boil the potatoes in salted water for 5-7 minutes, then drain and let them cool.
Cooking Techniques for Crispy Roast Potatoes
Now that we’ve covered the basics, let’s dive into the cooking techniques for achieving crispy roast potatoes.
High-Heat Roasting
High-heat roasting is the key to achieving crispy roast potatoes. Preheat your oven to 425°F (220°C) and roast the potatoes for 20-25 minutes, or until they’re golden brown and crispy.
Using the Right Oil
Using the right oil can help achieve crispy roast potatoes. Choose an oil with a high smoke point, such as avocado oil or grapeseed oil. Drizzle the oil over the potatoes and toss to coat.
Shaking the Pan
Shaking the pan halfway through the cooking time can help redistribute the potatoes and promote even browning.
Additional Tips and Tricks
Here are some additional tips and tricks to help you achieve crispy roast potatoes:
Using a Wire Rack
Using a wire rack can help promote air circulation and crispiness. Place the potatoes on a wire rack set over a baking sheet and roast as usual.
Adding Aromatics
Adding aromatics, such as garlic or rosemary, can enhance the flavor of the potatoes. Simply chop the aromatics and toss with the potatoes before roasting.
Broiling for Extra Crispiness
Broiling the potatoes for an extra 2-3 minutes can help achieve extra crispiness. Keep an eye on the potatoes to prevent burning.
Common Mistakes to Avoid
Here are some common mistakes to avoid when trying to achieve crispy roast potatoes:
Overcrowding the Pan
Overcrowding the pan can prevent the potatoes from cooking evenly and becoming crispy. Make sure to leave enough space between each potato for air to circulate.
Not Drying the Potatoes
Not drying the potatoes properly can prevent them from becoming crispy. Make sure to pat the potatoes dry with paper towels after soaking or parboiling.
Not Using Enough Oil
Not using enough oil can prevent the potatoes from becoming crispy. Make sure to drizzle enough oil over the potatoes to coat them evenly.

How do I choose the right potatoes for roasting?
Choosing the right potatoes for roasting is crucial to achieving the perfect crispy exterior and fluffy interior. Look for high-starch potatoes like Russet or Idaho, which have a dry, dense texture that yields a crisper exterior when roasted. Avoid using waxy potatoes like Yukon Gold or red potatoes, as they tend to retain their moisture and remain soft when roasted.
When selecting potatoes, also consider their size and shape. Larger potatoes can be cut into wedges or chunks, while smaller potatoes can be roasted whole or halved. Make sure to choose potatoes that are firm and free of bruises or blemishes, as these can affect the texture and flavor of the final dish. By choosing the right potatoes, you’ll be well on your way to creating deliciously crispy roast potatoes.
What is the best way to parboil potatoes before roasting?
Parboiling potatoes before roasting is an essential step in achieving crispy roast potatoes. To parboil potatoes, place them in a large pot of salted water and bring to a boil. Reduce the heat to a simmer and cook for 5-7 minutes, or until the potatoes are slightly tender when pierced with a fork.
After parboiling, drain the potatoes and let them cool slightly. This step helps to remove excess moisture from the potatoes, creating a rough surface for them to crisp up during roasting. Be careful not to overcook the potatoes during parboiling, as this can make them too soft and prone to breaking apart during roasting. By parboiling the potatoes just until they’re slightly tender, you’ll set them up for success in the roasting process.
How do I achieve a crispy exterior on my roast potatoes?
Achieving a crispy exterior on roast potatoes requires a combination of proper preparation, cooking technique, and attention to detail.
