These Crispy Roasted Potatoes are irresistibly golden and crunchy on the outside, with a fluffy interior. The secret to this recipe is boiling the potatoes first and then roasting them for maximum crispiness.
Adjust oven rack to center position and preheat oven to 400°F if using convection or 450°F if not.
Bring 2 quarts of water in a large pot over high heat to a boil while you prep the potatoes. Add 2 tablespoons of kosher salt and baking soda and stir to combine, then add the cut potatoes.
Return to a boil, reduce to a simmer, and cook until a knife meets little resistance when inserted into a potato chunk, about 10 minutes.
When potatoes are cooked, drain all the water out and let them rest in the pot for 30 seconds to allow excess moisture to evaporate.
Transfer to bowl, drizzle in the olive oil, and toss to coat, shaking bowl roughly, until a thick layer of mashed potato–like paste has built up on the potato chunks.
Transfer to a large rimmed baking sheet and separate them, spreading them out evenly. Transfer to oven and roast, without moving, for 20 minutes.
Using a flexible metal spatula to release any stuck potatoes, shake pan and turn potatoes. Continue roasting until potatoes are deep brown and crisp all over, turning and shaking them a few times during cooking, this should take about 30 to 40 minutes longer.
Prep the garlic herb sauce by combining the ingredients in a small bowl.
Once potatoes and crispy and fully cooked, add them to a large bowl with the garlic herb sauce. Toss to coat, taste and adjust season with any additional flaky sea salt to taste if needed. Serve immediately and enjoy!
Notes
To achieve the perfect crispy roast potatoes, it's essential to parboil them until a knife meets little resistance when inserted. This initial step is key to a fluffy interior and allows the potatoes to crisp up evenly in the oven.
Drizzle the potatoes with olive oil and toss them until a thick layer of mashed potato-like paste has built up on the potato chunks. This might seem unusual, but it's a crucial step for achieving an extra-crispy exterior.
Use a large rimmed baking sheet to roast the potatoes, and make sure to separate them and spread them out evenly. This allows for even browning and crispiness on all sides.
Don't be afraid to let the potatoes roast without moving for the first 20 minutes. This is the time when the crust is formed, so patience is key.
When the potatoes are deep brown and crisp all over, they're ready. This usually takes about 30 to 40 minutes after the initial 20 minutes of roasting.
The garlic herb sauce is a delicious addition and adds an extra layer of flavor. However, don't dress the potatoes too far in advance, or they can lose their crispiness.
Serve your crispy roast potatoes with the garlic herb sauce and season with any additional flaky sea salt to take this classic side dish to the next level.
