Ingredients

• 1 kg Yukon Gold potatoes or red potatoes, cut into 2.5 cm cubes
• 3 tablespoons extra virgin olive oil
• 4 garlic cloves minced
• 60 g freshly grated Parmesan cheese Parmigiano-Reggiano preferred
• 1 teaspoon sea salt
• ½ teaspoon black pepper freshly ground
• 2 tablespoons fresh parsley chopped, for garnish
• ½ teaspoon garlic powder optional, for extra garlic flavor

Instructions

1. Preheat your oven to 220°C (425°F). Line a large baking sheet with parchment paper or lightly oil it to prevent sticking.
2. Cut the potatoes into evenly-sized 2.5 cm cubes. Pat them completely dry with a clean kitchen towel—this step is crucial for achieving maximum crispiness.
3. In a large bowl, toss the dried potato cubes with olive oil, minced garlic, garlic powder (if using), salt, and black pepper until evenly coated.
4. Spread the potatoes in a single layer on the prepared baking sheet, ensuring they don't touch or overlap. Use a second baking sheet if necessary to avoid overcrowding.
5. Roast for 30-35 minutes, flipping the potatoes halfway through (around the 15-minute mark) to ensure even browning on all sides.
6. During the final 3-5 minutes of roasting, sprinkle the grated Parmesan cheese over the potatoes and return to the oven until the cheese is melted and golden.
7. Remove from the oven and let the potatoes rest for 2-3 minutes to maximize crispiness. Garnish with fresh parsley and serve immediately.

Chef’s Tips

• Dry the potatoes thoroughly after cutting—any residual moisture will steam the potatoes instead of crisping them.
• Don't skip the flip halfway through roasting. This ensures all sides develop that coveted golden crust.
• Add the Parmesan in the final minutes only. Adding it too early can cause the cheese to burn rather than melt into a delicious golden coating.
• For even crispier results, place the baking sheet on the lowest oven rack where heat is most intense.
• Let the potatoes rest briefly after roasting—this allows the exterior to firm up and become extra crunchy.

Common Mistakes to Avoid

• Overcrowding the baking sheet traps steam and prevents crisping. Always leave space between potato pieces or use two pans.
• Skipping the drying step leaves moisture on the potatoes, resulting in soggy rather than crispy exteriors.
• Adding Parmesan too early causes it to burn. Wait until the final 3-5 minutes for perfectly melted, golden cheese.
• Cutting potatoes into uneven sizes leads to inconsistent cooking—some pieces will be overcooked while others remain underdone.
• Using too low an oven temperature won't create the high heat needed for a crispy crust. Stick to 220°C for best results.

Variations

• Air Fryer Method: Cook at 200°C for 18-22 minutes, shaking the basket every 6-7 minutes. Add Parmesan in the final 2 minutes.
• Vegan Option: Replace Parmesan with nutritional yeast or vegan parmesan alternative for a dairy-free version with similar umami flavor.
• Herb Variations: Swap parsley for fresh rosemary, thyme, or oregano. Italian seasoning blend also works beautifully.
• Spicy Kick: Add ½ teaspoon red pepper flakes or smoked paprika to the oil mixture for a warming heat.
• Lemon Garlic: Toss finished potatoes with fresh lemon zest and a squeeze of lemon juice for bright, zesty flavor.

Storage

Store leftover crispy garlic parmesan potatoes in an airtight container in the refrigerator for up to 3 days. To reheat and restore crispiness, spread them on a baking sheet and bake at 200°C for 8-10 minutes until heated through and crispy again. Avoid microwaving, as this will make them soggy. For make-ahead prep, cut and soak potatoes in cold water up to 4 hours in advance, then drain and dry thoroughly before roasting.

Frequently Asked Questions

Can I make these potatoes in an air fryer?

Yes! Preheat your air fryer to 200°C and cook the seasoned potatoes for 18-22 minutes, shaking the basket every 6-7 minutes for even crisping. Add Parmesan during the final 2 minutes.

Should I soak potatoes before roasting?

Soaking isn't necessary for this recipe, but if you prep ahead, you can soak cut potatoes in cold water for up to 4 hours. Just be sure to drain and dry them completely before roasting.

What type of potatoes are best for roasting?

Yukon Gold and red potatoes are ideal because they hold their shape and develop a creamy interior. Russets work too but may be slightly fluffier and less firm.

Can I prep these potatoes ahead of time?

Yes, you can cut and soak the potatoes in cold water up to 4 hours before roasting. Drain, pat completely dry, and proceed with the recipe as directed.

How do I keep roasted potatoes from getting soggy?

Dry the potatoes thoroughly before roasting, avoid overcrowding the pan, and use high heat (220°C). Let them rest for 2-3 minutes after roasting to firm up the exterior.

Why aren't my potatoes crispy?

The most common causes are excess moisture, overcrowding the baking sheet, or oven temperature that's too low. Make sure potatoes are completely dry, well-spaced, and roasted at 220°C.
