The contrast between the shatteringly crisp exterior and the melt-in-your-mouth interior creates a sensory experience that’s utterly addictive.

Once you master these perfect roast potatoes, you’ll find yourself making them again and again – they’re that good.

Ingredients

For the perfect batch of crispy roast potatoes, gather:

• 4 pounds (1.8 kg) Russet or Yukon Gold potatoes
• 1/2 cup (120 ml) high-quality olive oil or duck fat
• 4 cloves garlic, minced (optional)
• 2 tablespoons fresh rosemary, chopped (optional)
• 1 tablespoon kosher salt
• 1 teaspoon freshly ground black pepper
• 1/2 teaspoon baking soda
• 2 tablespoons semolina or polenta (optional, for extra crispiness)
• Flaky sea salt for finishing

The baking soda is the secret weapon that helps break down the potato surface, creating more texture for ultimate crispiness, while semolina creates an additional crunchy coating. Yukon Golds offer buttery flavor, while Russets provide maximum fluffiness inside.

Pro Tips

The difference between good and extraordinary crispy roast potatoes comes down to technique. First, parboiling is non-negotiable – cook the potatoes in heavily salted water with baking soda until the edges just start to soften and roughen up (about 10 minutes). This creates the perfect surface for crisping.

Second, the roughing up technique is crucial. After draining, return potatoes to the pot and shake vigorously to create a mashed potato-like coating on the exterior. This starchy coating, when exposed to high heat, transforms into a glass-like crust.

Finally, ensure your fat is screaming hot before adding potatoes. Preheat the oil in the roasting pan for at least 10 minutes until it’s shimmering. When potatoes hit this hot fat, they’ll immediately begin forming that crucial crisp exterior rather than soaking up oil. This prevents the dreaded soggy potato syndrome that plagues lesser roast potato recipes.

Instructions

Step 1: Prepare and Parboil

Preheat your oven to 450°F (230°C). Cut your potatoes into even chunks about 2-3 inches in size – consistency is key for even cooking. Fill a large pot with cold water, add 1 tablespoon kosher salt and 1/2 teaspoon baking soda, then add your potatoes. Bring to a boil and cook for 8-10 minutes until the edges start to soften but the centers remain firm. You’re creating the foundation for that perfect texture contrast.

Step 2: Rough Up the Potatoes

Drain the potatoes thoroughly in a colander. Return them to the empty pot and give them a good shake – don’t be gentle here! You want to create a rough, fluffy exterior on each piece. This starchy coating will transform into your crispy shell. If using, sprinkle the semolina over the potatoes now and shake again to coat.

Step 3: Prepare the Fat

While the potatoes are parboiling, place your chosen fat (olive oil or duck fat) in a large roasting pan and place in the oven to heat for at least 10 minutes. The fat must be extremely hot when the potatoes are added – this is non-negotiable for achieving maximum crispiness!

Step 4: Roast to Perfection

Carefully remove the hot pan from the oven. Working quickly but cautiously, tip the roughed-up potatoes into the hot fat. They should sizzle immediately – that’s a good sign! Use a spatula to turn each potato to coat in the fat, then spread them out in a single layer with plenty of space between pieces.

Step 5: The Roasting Process

Roast for 30 minutes, then remove from the oven and turn each potato using a spatula. Return to the oven for another 20-30 minutes. If adding garlic and rosemary, toss them in during the final 20 minutes to prevent burning. The potatoes are done when they’re deeply golden brown, crispy all over, and tender inside when pierced with a fork.

Step 6: The Finishing Touch

Transfer to a serving dish lined with paper towels to absorb any excess oil. Sprinkle with flaky sea salt while still hot and serve immediately for maximum crispiness. Watch them disappear before your eyes!

Variations

Herb and Parmesan Crispy Potatoes: After the final flip, sprinkle 1/3 cup freshly grated Parmesan cheese and 2 tablespoons mixed fresh herbs (thyme, parsley, and chives work beautifully) over the potatoes for the last 10 minutes of roasting. The cheese creates an additional crispy, savory crust that’s utterly irresistible.

Spicy Crispy Roast Potatoes: For heat-seekers, add 2 teaspoons smoked paprika, 1 teaspoon cayenne pepper, and 1 teaspoon garlic powder to the hot oil before adding the potatoes. Finish with chopped fresh cilantro and a squeeze of lime juice for a Mexican-inspired version that pairs perfectly with grilled meats.

Truffle Crispy Potatoes: For a luxurious twist, toss the finished crispy roast potatoes with 2 tablespoons truffle oil and 2 tablespoons finely chopped fresh parsley. The earthy, aromatic truffle elevates this humble side dish to restaurant-quality status, perfect for special occasions.

Storage and Serving

While crispy roast potatoes are best enjoyed fresh from the oven, leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place on a baking sheet in a 400°F (200°C) oven for 10-15 minutes until hot and crispy again. Avoid microwaving, as this will render your once-crispy potatoes sadly soggy.

For serving, these potatoes shine alongside a Sunday roast with gravy, but don’t limit them to traditional pairings. They make an excellent base for loaded potatoes – top with sour cream, chives, bacon, and cheese for an elevated appetizer. For brunch, top with a poached egg and hollandaise for a creative twist on hash.

For a complete meal, serve alongside a simple protein like roast chicken or pan-seared steak with a bright, acidic salad to cut through the richness of the potatoes.

FAQs

Why aren’t my roast potatoes getting crispy?
The most common culprit is overcrowding the pan. Potatoes need space for steam to escape; otherwise, they steam instead of roast. Also ensure your fat is very hot before adding potatoes and that your oven temperature is accurate.

Can I make crispy roast potatoes ahead of time?
You can parboil, rough up, and cool the potatoes up to a day ahead. Store in the refrigerator, then roast in hot oil when needed. They may take slightly longer from cold.

Which potatoes are best for crispy roast potatoes?
Starchy varieties like Russets or all-purpose potatoes like Yukon Golds work best. Waxy potatoes won’t develop the same fluffy interior.

Is duck fat really worth it for roast potatoes?
Duck fat has a high smoke point and imparts incredible flavor, making potatoes exceptionally crispy. It’s worth trying at least once, though good olive oil also yields excellent results.

Can I make these potatoes without parboiling?
Parboiling is essential for developing the starchy exterior that becomes crispy. Without this step, potatoes will be crisp only on the outside without the contrasting textures that make this recipe special.
