How to Make Roast Potatoes

Preheat the Oven

• Preheat your oven to 180°C (350°F).

Prepare the Potatoes

• Wash and peel the potatoes.
• Cut them into halves or quarters, ensuring they are all about the same size for even cooking.

Parboil the Potatoes

• Parboil the potatoes in salted water for 10-12 minutes to start the cooking process and help achieve a fluffy interior.

Drain and Steam the Potatoes

• Drain the potatoes in a colander.
• Leave them to steam dry for 2 minutes, which helps the fat stick to the potatoes.

Coat the Potatoes in Fat

• Place melted duck or goose fat and 1 tablespoon of olive oil in a large bowl.
• Add the potatoes and toss to coat them evenly.
• Pack the potatoes (flat side down) on a large baking sheet lined with baking paper.
• Generously season with salt and pepper.
• Squash the garlic bulbs, lightly crush each unpeeled clove, toss in the remaining duck fat and add to the baking sheet.

Roast the Potatoes

• Roast for 40-45 minutes or until the potatoes are crisp and golden all over.
• Halfway through, remove the baking sheet from the oven, turn the potatoes around, and gently squash each one with a masher to increase the crispy surface area.

Serve and Enjoy

• Remove the potatoes from the oven and serve them hot.
• Enjoy your crispy, golden roasted potatoes!

Chef’s Tips

• Room Temperature: Always bring leftover roast potatoes to room temperature before reheating for even warming.
• Single Layer: Spread potatoes in a single layer on a baking sheet to ensure they reheat evenly and stay crispy.
• Medium-High Heat: Reheat at medium-high heat (around 400°F) to achieve the best results and maintain crispy skin.
• Aluminum Foil: Cover potatoes with aluminum foil for the first half of reheating to retain moisture, then remove it to let them crisp up.
• Use Sunflower Oil: A light coating of sunflower oil before reheating can help revitalize the crispy texture of your potatoes.
