The key is in the method, so follow it to the letter.
Cooking Time (Includes Preparation Time): 1 Hour 30 Minutes
1kg Maris Piper Potatoes
4 Tablespoons Goose Fat
A whole Head of Garlic
Bunch of Thyme
Bunch of Rosemary
Preheat oven to 180°C/356°F.
Peel your potatoes and cut in to quarters. Add them to a pan of boiling water with a large pinch of salt. Parboil for 10 minutes.
While the potatoes are cooking, add 4 tablespoons of goose fat to a roasting tray. Place tray in the oven for 10 minutes, just so the fat can melt and heat through.
Drain your potatoes, and then re-add to the pan. Place a lid on top, and then give them a good shake. Remove the lid. The outside of the potatoes should be nice and fluffy. This is KEY to the crispiness.
Pour your fluffy potatoes in to the roast tray. Add 10-12 whole cloves of garlic (skin on), a large handful of rosemary, a large handful of thyme, a big pinch of salt and some pepper. Toss everything together, and then place the potatoes in the oven for 1 hour and 15 minutes.
Next key part - the mid-cook tossing. Every 25 minutes, you need to remove the roasting tray from the oven, and gently turn the potatoes in the goose fat. This will ensure a nice even golden outside.
Once the potatoes are gold all over, remove from the oven. Serve with some salt sprinkled on top and enjoy!
