Instructions
- Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper for easy cleanup and to prevent sticking.
- Prepare the potatoes: If using small baby potatoes, you can leave them whole. If using Yukon Golds, cut them in half lengthwise. Try to keep the pieces roughly uniform in size to ensure even cooking.
- Blanch the potatoes (optional, but highly recommended for extra crispiness): Place the cut potatoes in a large pot and cover with cold water by about an inch. Add a generous pinch of salt. Bring to a boil over high heat, then reduce heat to medium and simmer for 5-7 minutes, or until the potatoes are just fork-tender but not mushy.
- Drain the potatoes very well in a colander. Allow them to steam dry for a few minutes. This step is crucial for achieving maximum crispness. You can even gently shake the colander to rough up the edges slightly, which creates more surface area for crisping.
- In a large bowl, combine the olive oil, grated Parmesan cheese, minced garlic, chopped parsley, chopped rosemary (if using), salt, black pepper, and red pepper flakes (if using).
- Add the drained potatoes to the bowl with the seasoning mixture. Toss gently but thoroughly, ensuring every potato piece is evenly coated with the fragrant mixture.
- Arrange the seasoned potatoes in a single layer on the prepared baking sheet. Make sure not to overcrowd the pan; if necessary, use two baking sheets. Overcrowding will steam the potatoes instead of roasting them, preventing them from getting crispy.
- Roast for 25-35 minutes, flipping the potatoes halfway through, until they are deeply golden brown, incredibly crispy on the outside, and tender on the inside. The exact cooking time will depend on the size of your potato pieces and your oven.
- Once roasted to perfection, remove the baking sheet from the oven.
- Transfer the crispy potatoes to a serving dish. Garnish with a little extra fresh parsley and a sprinkle of Parmesan cheese, if desired. Serve immediately and watch them disappear!
Cooking Tips and Variations
For the ultimate crispy exterior, don’t skip the blanching step! It helps break down the potato’s starch, leading to a much crispier result. Also, ensure your potatoes are completely dry before tossing them with the oil and seasonings. Moisture is the enemy of crispiness.
When arranging the potatoes on the baking sheet, give them space. Air circulation is key to achieving that coveted crunch. If they’re too close, they’ll steam rather than roast. If your oven has a convection setting, use it for even crispier results.
Feel free to experiment with different herbs! Thyme, oregano, or a mix of Italian herbs would all be delicious. For a touch of heat, increase the red pepper flakes or add a dash of cayenne pepper. You can also add a squeeze of fresh lemon juice over the finished potatoes for a bright, zesty finish.
To make these a heartier side, consider adding some chopped onions or bell peppers to roast alongside the potatoes. For an extra layer of flavor, you could even add a tablespoon of nutritional yeast to the seasoning mix for a cheesier, umami boost.
Storage and Reheating
Leftover Parmesan garlic herb roasted potatoes can be stored in an airtight container in the refrigerator for up to 3-4 days. While they are best enjoyed fresh, they still make a delicious addition to meals later in the week.
To reheat, preheat your oven or toaster oven to 375°F (190°C). Spread the potatoes in a single layer on a baking sheet. Reheat for 10-15 minutes, or until thoroughly heated through and re-crisped. Avoid using a microwave, as it will make the potatoes soft and lose their desirable crispy texture.
You can also reheat them in an air fryer at 375°F (190°C) for 5-8 minutes, shaking the basket halfway through, for excellent results that bring back much of their original crispness.
Frequently Asked Questions
What kind of potatoes work best for this recipe?
Small Yukon Gold potatoes or baby potatoes are ideal for this recipe. Their waxy texture holds up well to roasting, and their thin skins get incredibly crispy. Avoid starchy potatoes like Russets, as they tend to fall apart and get too floury.
Can I make these potatoes ahead of time?
While these potatoes are absolutely best served immediately after roasting for peak crispiness, you can prep them partially ahead. You can blanch the potatoes and let them cool, storing them in the fridge. Then, toss them with the seasoning and roast just before serving. However, for the best texture, I recommend cooking them fresh.
My potatoes aren’t getting crispy, what am I doing wrong?
There are a few common culprits! Ensure you’re not overcrowding the baking sheet; use two if necessary. Make sure the potatoes are thoroughly dry after blanching (or washing, if you skip blanching). Your oven temperature might not be hot enough, or you might not be cooking them long enough. Also, a good quality olive oil helps in achieving that perfect golden crust.
