How to Make Perfectly Crisp Roast Potatoes: A Step-by-Step Guide with Tips and FAQs

Roast potatoes are a classic side dish that’s loved for their crispy exterior and fluffy interior. Achieving the perfect crispiness can seem elusive, but with the right technique, you can make roast potatoes that are golden, crunchy, and absolutely irresistible. Below, you’ll find a detailed recipe, helpful tips, and answers to common questions to help you master the art of making perfectly crisp roast potatoes.

Ingredients:

  • 2 lbs (about 1 kg) potatoes (Yukon Gold, Russet, or Maris Piper are ideal)
  • 1/4 cup (60 ml) olive oil, vegetable oil, or duck fat for extra richness
  • 1 teaspoon salt (plus more to taste)
  • 1/2 teaspoon black pepper
  • 1 teaspoon garlic powder (optional)
  • 1 teaspoon dried rosemary, thyme, or your favorite herb (optional)
  • Fresh parsley or chives for garnish (optional)

Instructions:

  1. Preheat the Oven: Preheat your oven to 425°F (220°C). If using a convection oven, reduce the temperature to 400°F (200°C).
  2. Peel and Cut the Potatoes: Peel the potatoes and cut them into evenly sized chunks. If you prefer the skins on, you can leave them unpeeled, but be sure to wash them thoroughly.
  3. Parboil the Potatoes: Place the potato chunks in a large pot and cover them with cold water. Add a teaspoon of salt and bring to a boil. Once boiling, reduce the heat and simmer for about 8-10 minutes, until the edges are slightly softened but the centers are still firm.
  4. Drain and Rough Up the Potatoes: Drain the potatoes in a colander and allow them to steam dry for a few minutes. To achieve extra crispiness, give the colander a good shake to rough up the edges of the potatoes. This rough texture will create the crispy surface when roasted.
  5. Heat the Oil: While the potatoes are steaming dry, pour the oil or fat into a large baking tray and place it in the preheated oven for about 5 minutes, until the oil is hot and shimmering.
  6. Coat the Potatoes: Carefully remove the hot tray from the oven and add the potatoes. Toss them in the hot oil, ensuring each piece is well coated. This step is crucial for creating a crispy exterior. Season with salt, pepper, garlic powder, and herbs if using.
  7. Roast the Potatoes: Spread the potatoes out in a single layer on the baking tray, making sure they’re not touching each other to allow even roasting. Return the tray to the oven and roast for 45-60 minutes, turning the potatoes every 20 minutes to ensure they brown evenly on all sides.
  8. Serve: Once the potatoes are golden and crispy, remove them from the oven. Taste and adjust the seasoning if necessary. Garnish with fresh parsley or chives, and serve hot.

Tips for the Crispiest Roast Potatoes

  • Choose the Right Potatoes: Starchy potatoes like Russets or Maris Piper are best for crispy roast potatoes because they have a fluffy interior and form a great crust when roasted. Waxy potatoes can also work but won’t be as fluffy inside.
  • Don’t Skip the Parboil: Parboiling the potatoes before roasting is essential for achieving a fluffy interior. It also helps rough up the surface, which is key to getting that crispy texture.
  • Hot Oil is Key: Adding the potatoes to hot oil or fat ensures that they start crisping up immediately. This step helps seal in the moisture and prevents the potatoes from sticking to the pan.
  • Don’t Overcrowd the Pan: To get the best crispy texture, make sure the potatoes have plenty of space on the baking tray. Overcrowding leads to steaming instead of roasting, which will make the potatoes soggy.
  • Use a High Heat: Roasting at a high temperature, like 425°F (220°C), is crucial for achieving a crispy exterior. If your oven has a convection setting, use it to enhance the crispiness.

Frequently Asked Questions

1. Can I make roast potatoes ahead of time?

Yes, you can parboil and rough up the potatoes ahead of time. After this step, let them cool completely, then store them in the refrigerator for up to 24 hours. When ready to roast, proceed with heating the oil and roasting as directed.

2. How do I store and reheat leftovers?

Store leftover roast potatoes in an airtight container in the refrigerator for up to 3 days. To reheat, place them on a baking tray and warm them in a 400°F (200°C) oven for about 10-15 minutes, or until they are hot and crispy again.

3. Can I use butter instead of oil?

Butter can be used, but it has a lower smoke point than oil, so it may burn if the oven is too hot. If you prefer the flavor of butter, you can mix it with oil or add it in the last 10 minutes of roasting.

4. Why aren’t my potatoes crispy?

If your potatoes aren’t turning out crispy, it could be due to not enough oil, overcrowding on the tray, or not roasting at a high enough temperature. Also, make sure to rough up the potatoes after parboiling for the best results.

5. Can I add other seasonings or spices?

Absolutely! You can customize your roast potatoes with different seasonings. Try adding smoked paprika, cumin, or even a sprinkle of Parmesan cheese in the last 5 minutes of roasting for added flavor.


Crispy roast potatoes are a timeless side dish that pairs well with almost any main course. With the right technique and a little patience, you can achieve perfectly golden, crunchy potatoes that will steal the show at any meal.
