Step‑by‑Step Instructions for Crispy Roast Potatoes with Rosemary and Garlic
Step 1: Preheat the Oven
Begin by preheating your oven to 425°F (220°C). This high temperature will ensure your Crispy Roast Potatoes with Rosemary and Garlic achieve that perfect crunchy exterior. Use a reliable oven thermometer to confirm the temperature, allowing those potatoes to roast evenly for maximum crispiness.
Step 2: Parboil the Potatoes
Place the cut yellow potatoes into a large pot of salted water. Bring it to a boil over high heat and allow the potatoes to simmer for about 10-15 minutes, just until they are tender but not fully cooked. This crucial step helps to soften the potatoes while preserving their shape for roasting.
Step 3: Cool and Drain the Potatoes
Once parboiled, carefully drain the potatoes in a colander. To stop the cooking process, rinse them under cold water for a few seconds, then drain again thoroughly. This technique not only prevents them from becoming mushy but also helps in achieving that crispy texture when roasted.
Step 4: Season the Potatoes
Transfer the drained potatoes back to the pot and sprinkle in the baking soda, kosher salt, freshly-cracked black pepper, and duck fat. Toss everything gently together until each potato is evenly coated, ensuring the baking soda is distributed well. This mixture is vital for that desired crunch in your Crispy Roast Potatoes with Rosemary and Garlic.
Step 5: Prepare for Roasting
Spread the seasoned potatoes in a single layer on a baking sheet lined with parchment paper, ensuring there’s space between each piece. Nestle the whole head of garlic and sprinkle the chopped rosemary among the potatoes. This allows the flavors to mingle while roasting, creating a delicious aroma.
Step 6: Roast the Potatoes
Place the baking sheet in the preheated oven and roast the potatoes for about 1 hour and 25 minutes. Be sure to flip the potatoes halfway through to ensure even browning and crisping. You’ll know they’re ready when they turn golden-brown and crispy, inviting you to dig in.
Step 7: Add the Finishing Touch
Once the potatoes are out of the oven, delight in the heavenly aroma and sprinkle flaky sea salt over the top while they are still warm. This final step enhances the flavor of your Crispy Roast Potatoes with Rosemary and Garlic, making each bite utterly satisfying and delicious.
