It wasn't until I understood the science of starch and the magic of alkaline water that I finally mastered the ultimate crispy roasted potatoes. This recipe isn't just a side dish; it is a labor of love that transforms a humble root vegetable into the star of the plate.

Key Ingredient Notes
To achieve the ultimate crispy roasted potatoes, you cannot simply grab any bag of spuds from the pantry. The choice of potato is the most critical factor. I highly recommend using Russet potatoes or Yukon Golds. Russets have a high starch content which leads to a fluffier interior and a crispier skin, while Yukon Golds offer a buttery flavor and a slightly more waxen but still delicious crunch.

Another essential ingredient for the ultimate crispy roasted potatoes is baking soda. Adding a small amount to the boiling water breaks down the pectin in the potato and draws the starch to the surface, creating more surface area for crisping. Finally, the fat choice is paramount. While olive oil works well, using duck fat or beef tallow will take your ultimate crispy roasted potatoes to a level of richness you never thought possible. If you prefer a lighter side, stick to a high-quality extra virgin olive oil for your ultimate crispy roasted potatoes.

Step-by-Step Guide with Pro Tips
Making the ultimate crispy roasted potatoes requires patience and attention to detail. First, you must peel and cut your potatoes into relatively large chunks. If they are too small, they will disintegrate during the parboiling phase. Once cut, place them in a pot of cold water. Starting with cold water ensures that the ultimate crispy roasted potatoes cook evenly from the outside in. Add a generous amount of salt and a half-teaspoon of baking soda. Bring the pot to a boil and let them simmer until the edges are soft but the centers still have a bit of resistance. This is the secret to the ultimate crispy roasted potatoes. After draining, let them steam dry for a few minutes. This step is crucial; excess moisture is the enemy of the ultimate crispy roasted potatoes. Once dry, give the pot a vigorous shake. You want the edges of the potatoes to look fuzzy or mashed. This fuzzy layer is what will eventually become the crunch of the ultimate crispy roasted potatoes. Preheating your roasting pan with the oil in the oven is another pro tip for the ultimate crispy roasted potatoes. When the hot potatoes hit the hot oil, they begin searing immediately. Roast at a high temperature, turning occasionally, until they are deep golden brown. The result will be the ultimate crispy roasted potatoes of your dreams.

FAQs
Why do you add baking soda to the potato water?
Adding baking soda to the water breaks down the potato's pectin and draws starch to the surface. This creates more surface area, which results in a much crispier crust when roasted.
Can I make these ultimate crispy roasted potatoes ahead of time?
You can parboil and fluff the potatoes up to a day in advance. Store them in the fridge uncovered to dry out further, then roast them right before serving for maximum crunch.
What is the best way to reheat crispy roasted potatoes?
To maintain the crunch, reheat them in a 400u00b0F oven or an air fryer for 5-10 minutes. Avoid the microwave as it will make them soggy.

A fool-proof recipe for achieving the crunchiest, most flavorful roasted potatoes with a soft, fluffy center using a secret parboiling technique.
Ingredients
2 lbs Russet or Yukon Gold potatoes, peeled and cut into 2-inch chunks
1/2 tsp baking soda
1 tsp kosher salt (plus more for boiling)
1/2 tsp freshly ground black pepper
1/4 cup extra virgin olive oil or duck fat
2 sprigs fresh rosemary, finely chopped
