What is the secret ingredient for crispy roast potatoes?

The secret lies in combining cornstarch or semolina with a drizzle of olive oil before roasting. This blend creates a fine coating that crisps under high heat while locking in moisture. Add freshly grated Parmesan for a nutty crunch that elevates texture and taste. The result is a crisp exterior that shatters gently when bitten, revealing soft, tender centers.

Is it necessary to boil potatoes before roasting?

Boiling isn’t mandatory, but it can make your Parmesan Crusted Roasted Potatoes even fluffier. Parboiling softens the outer layer, allowing the oil and cheese to cling better. However, Lily Taylor often skips this step for simplicity, relying instead on drying the raw chunks thoroughly before roasting. Both methods yield delicious results it’s simply a matter of preference.

What makes roast potatoes really crispy?

True crispiness comes from three key elements: dry surfaces, high heat, and even spacing on the baking tray. When potatoes are spread in a single layer and left undisturbed during the first half of roasting, they brown evenly. Using parchment paper or a preheated tray also helps prevent steaming, ensuring those golden, crunchy edges that make this dish irresistible.

How to make Parmesan roasties?

To make perfect Parmesan Crusted Roasted Potatoes, coat potato chunks in olive oil, a teaspoon of cornstarch, and your favorite spices. Add grated Parmesan, then spread them out on a baking sheet. Roast at 220°C (425°F) for 40 minutes, flipping once halfway through. Finish with a light sprinkle of cheese for an extra layer of crispness. Serve immediately while the crust is still hot and fragrant.
