Why This Recipe Works

Before diving into the details, let me explain why this particular recipe stands out from others you might have tried:

Equipment Needed

Having the right tools makes a big difference when preparing this dish:

• Large pot for parboiling potatoes
• Colander for draining
• Large rimmed baking sheet (I recommend 18×13 inches)
• Parchment paper or silicone baking mat
• Sharp knife for cutting potatoes
• Kitchen towel for drying potatoes
• Measuring spoons and cups
• Mixing bowls (one large, one medium)

Step-by-Step Instructions for Crispy Parmesan Potatoes

Preparation Phase

1. Preheat your oven to 425°F (220°C) and position a rack in the middle.
2. Wash the potatoes thoroughly under cold running water. I don’t peel mine – the skins add extra crispiness and nutrition.
3. Cut the potatoes into 1-inch cubes. Try to keep the pieces roughly the same size for even cooking.
4. Fill a large pot with cold water and add 1 tablespoon of salt.

Par-boiling Stage

5. Add the potatoes to the cold salted water and bring to a boil over high heat.
6. Reduce to a simmer and cook for 6-8 minutes. You want them partially cooked but still firm – they should offer resistance when pierced with a fork.
7. Drain thoroughly in a colander and let them steam dry for 5 minutes.
8. Transfer to a clean kitchen towel and pat completely dry. This step is crucial – excess moisture is the enemy of crispiness!

Seasoning and First Roast

9. In a large bowl, combine olive oil, cornstarch, garlic powder, rosemary, thyme, salt, and pepper.
10. Add the dried potatoes to the bowl and toss gently until every piece is evenly coated with the seasoning mixture.
11. Line your baking sheet with parchment paper or a silicone mat and spread the potatoes in a single layer, making sure they aren’t touching each other.
12. Roast for 20 minutes, then remove from the oven and carefully flip each piece with a spatula.

Parmesan Application and Final Roast

13. Return to the oven for another 15 minutes.
14. Remove the baking sheet and sprinkle the Parmesan cheese evenly over the potatoes.
15. Roast for a final 5-7 minutes, or until the cheese is melted and beginning to crisp and turn golden brown.
16. Remove from oven and let cool for 5 minutes before transferring to a serving dish.
17. Garnish with fresh parsley just before serving.

Even experienced cooks can run into challenges with crispy potatoes. Here are solutions to common problems:

Make-Ahead and Storage Tips

This dish is best enjoyed fresh from the oven, but there are ways to prepare components ahead of time:

• Parboiled potatoes: Can be refrigerated for up to 24 hours. Just make sure they’re completely dry before storing in an airtight container.
• Seasoning mix: Can be prepared up to a week in advance and stored in an airtight container at room temperature.
• Fully cooked leftovers: Store in the refrigerator for up to 3 days in an airtight container.

Reheating Instructions

To restore crispiness when reheating:

1. Preheat oven to 375°F (190°C).
2. Spread potatoes on a baking sheet lined with parchment paper.
3. Reheat for 10-15 minutes until heated through and crispy again.
4. Avoid microwaving if possible, as it will make the potatoes soggy.

Serving Suggestions

The beauty of these crispy Parmesan potatoes is their versatility. Beyond the complete dinner options I’ve outlined, here are some additional serving suggestions:

• Dipping sauces: Serve with garlic aioli, truffle mayonnaise, or sriracha mayo for an appetizer or side dish

Recipe Variations

While I think this recipe is nearly perfect as written, there are several variations you might want to try:

Flavor Variations

• Mediterranean: Add 1 teaspoon of dried oregano to the seasoning mix and replace ¼ cup of the Parmesan with crumbled feta cheese
• Spicy: Add ½ teaspoon of cayenne pepper to the seasoning mix and top with chopped jalapeños along with the Parmesan
• Loaded baked potato style: After adding the Parmesan, top with 2 tablespoons of cooked, crumbled bacon and return to the oven, then garnish with sour cream and chives
• Truffle version: Add ½ teaspoon of truffle oil to the olive oil mixture and garnish with fresh thyme instead of parsley
• Ranch flavor: Replace the herbs with 2 tablespoons of ranch seasoning mix

Ingredient Substitutions

If you need to accommodate dietary restrictions or simply don’t have all ingredients on hand, here are some substitutions that work well:

Tips for Perfect Results Every Time

After making this recipe countless times, I’ve discovered several key techniques that ensure success:

1. Start with cold water when parboiling the potatoes—this ensures even cooking from the inside out.
2. Don’t skip the drying step after parboiling—moisture is the enemy of crispiness.
3. The cornstarch trick is non-negotiable—it creates that extra-crispy exterior that makes these potatoes special.
4. Use a metal baking sheet if possible—it conducts heat better than glass or ceramic dishes.
5. Don’t overcrowd the pan—each potato piece needs space around it for proper air circulation and browning.
6. Season generously—potatoes can handle a good amount of salt and herbs.
7. Freshly grate your Parmesan—pre-grated cheese often contains anti-caking agents that prevent proper melting.
8. Let the potatoes rest for 5 minutes after removing from the oven—this allows the exterior to set and become even crispier.

Questions and Answers

I often receive questions about this recipe, so here are answers to the most common ones:

Can I make these potatoes without parboiling? You can, but you won’t achieve the same contrast between the ultra-crispy exterior and fluffy interior. If skipping this step, you’ll need to extend the roasting time by about 15-20 minutes and may need to lower the temperature slightly to prevent burning.

Why is my Parmesan not crisping up? This usually happens if your Parmesan is too thickly grated or if your oven temperature isn’t hot enough. Make sure to use finely grated cheese (not the powdery pre-grated kind, but not coarsely shredded either). Also, ensure your oven is fully preheated to 425°F.

Can I use sweet potatoes instead? Yes, but they won’t get quite as crispy due to their higher sugar content. If using sweet potatoes, I recommend adding a bit more cornstarch (an extra teaspoon) and extending the final roasting time by 3-5 minutes.

How do I make this recipe vegan? Replace the Parmesan with 4 tablespoons of nutritional yeast mixed with ½ teaspoon of garlic powder and ¼ teaspoon of salt. Add this mixture in the last 5 minutes of cooking, just as you would the Parmesan.

Can I prepare these in an air fryer? Absolutely! Parboil as directed, then air fry at 400°F for about 15 minutes, shaking the basket halfway through. Add the Parmesan and air fry for an additional 3-5 minutes until crispy.

Why add the Parmesan at the end instead of mixing it with the potatoes from the start? Adding the cheese too early would cause it to burn before the potatoes are fully crispy. Adding it for just the last few minutes allows it to melt and crisp perfectly without burning.

How do I know when the potatoes are done? They should be deeply golden brown with visible crispy edges, and the cheese should be melted and starting to brown. If you’re unsure, take one out and test it – it should be crispy on the outside and tender on the inside.

Final Thoughts

These Ultimate Crispy Parmesan Potatoes have become my signature dish for good reason. The combination of techniques—parboiling, thorough drying, cornstarch coating, proper spacing, and strategic cheese application—creates a potato dish that’s truly exceptional.

What I love most about this recipe is how it can transform an ordinary dinner into something special without requiring professional culinary skills. The step-by-step approach makes it accessible even to novice cooks, while the results will impress even the most discerning food lovers.

Whether you’re serving these potatoes as part of a complete dinner with one of the protein options I’ve suggested, or simply as an elevated side dish, I’m confident they’ll become a favorite in your recipe collection. The versatility of this dish means it works equally well for a Tuesday family dinner or a Saturday dinner party.
