A good roast potato has to be up there as one of life's great joys, and one Michelin-trained chef says this recipe for hers may be the best on earth. 

Giving new meaning to the phrase 'good things take time', TikTok star and chef Poppy O'Toole has shared her recipe that involves slicing, marinating, weighing down, baking, and frying potatoes, all to create a delicious, crunchy result. 

In fact, the whole process takes around 15 hours. That may sound insane but actually is ideal for New Zealanders sheltering in their homes during COVID-19 alert level 4 lockdown. What else are you going to do with your time?

In the recent video, O'Toole revealed the potato bake requires four ingredients: Rendered beef fat (drippings), sea salt, potatoes and vegetable oil.

"Three hours in the oven at 130C, 12 hours in the fridge to set, before deep-frying at 190C," she explained.

Poppy O'Toole's crispy roast potato bake recipe:

Ingredients

  • 1 cup rendered beef fat
  • 1 tablespoon sea salt
  • 3 pounds Maris Piper or russet potatoes
  • 4 cups vegetable oil

Method

  1. Preheat the oven to 130C.
  2. Peel, wash, then thinly slice potatoes with a mandolin.
  3. Add sliced potatoes to a bowl of beef fat and salt, then toss well to ensure each slice is fully saturated.
  4. Line a loaf pan with parchment paper, and layer potato slices evenly, one by one.
  5. Cover the top with parchment paper, and place in oven for three hours or until fork-tender.
  6. After three hours, remove potatoes from oven, then compress with cans or any heavy object.
  7. Place in the refrigerator, and chill for 12 hours.
  8. After 12 hours, remove potatoes from the loaf pan, and cut into rectangular segments.
  9. Heat vegetable oil to 190C and lower potatoes into pot, deep frying for 3-5 minutes until golden brown.
  10. Remove from the pot, then let cool before sprinkling with salt.
