    ✔️ Why you'll love this recipe!

    1. Crispy golden brown roast potatoes.
    2. Perfect for Christmas and special occasions.
    3. Easy to make.

    🛒 Ingredient notes

    Ingredients for duck fat roast potatoes.

    Potatoes - I like to use starchy potatoes like Maris Piper or King Edward varieties, but any regular white potato can be used.

    Duck Fat - either bought from the supermarket or collected from a roasting duck halfway through cooking.

    Plain Flour - to help crisp up the potatoes.

    Rosemary - a couple of sprigs of rosemary in the roasting tin gives the potatoes a subtle herby flavour.

    Garlic - you'll need 3 unpeeled cloves of garlic for the roasting tin.

    Sea Salt - for flavour.

    🔪 Instructions

    The recipe card with ingredient quantities and detailed instructions can be found at the bottom of the post

    One: Peel and cut the potatoes into even chunks (I generally cut a medium potato into 3 pieces). Put the potatoes into a large pan of salted water and bring it to the boil. Once the water is boiling, immediately turn down the heat to low and time 4 minutes.

    Two: Take the pan off the heat, drain the potatoes in a colander, and allow to steam dry. Shake the colander to fluff up the edges.

    Three: Sprinkle over the flour and make sure each potato is coated.

    Four: Heat the oven to 220 °C (200 °fan/ Gas 7) and pour the duck fat into a roasting tin. Heat the roasting tray in the oven for 5 minutes until the fat is very hot.

    Five: Carefully take the roasting tin out of the oven and place the potatoes in the hot fat, using a spoon to turn each potato in the duck fat. Pop in the garlic cloves and rosemary sprigs and sprinkle over the sea salt. Roast the potatoes in the oven for 50 minutes to 1 hour until they are golden and crispy.

    💡 Top Tip - turn the potatoes halfway through cooking to ensure they cook evenly and are a nice golden brown colour.

    Top Tips

    • You can reuse the duck fat after roasting the potatoes. Just strain out any bits of potato, then allow it to cool before scraping it into a jar. Store in the fridge for up to a month.
    • Use starchy potatoes, not waxy ones, for the best fluffy texture.
    • Roughing up the surface of the potatoes after parboiling them creates more surface area, which in turn equals crispier crunchier potatoes!
    • Glass roasting/baking dishes are not recommended due to the high oven temperatures.

      🍴 What to serve with duck fat roast potatoes

      Serve the duck fat roast potatoes with your favourite roast meats such as chicken, beef and turkey, and alongside other vegetable sides such as cauliflower cheese, red cabbage, roasted Tenderstem broccoli, air fryer Brussels sprouts, and honey-roasted carrots and parsnips.

      📖 Variations

      • Use goose fat instead of duck fat.
      • Use semolina or polenta instead of plain flour.
      • Swap the rosemary for thyme or oregano.
      • Use baby potatoes instead of regular white potatoes.
      • Roast the duck fat potatoes in your air fryer instead of the oven.

      🥡 Storage

      Make Ahead - Peel and chop the potatoes the day before and place them in a pan of cold water overnight.

      Store - Leftover roast potatoes can be stored in an airtight container in the fridge for up to 3 days.

      Reheat - Air fry or reheat in a hot oven to retain their crispness.

      Freeze - Allow the duck fat roast potatoes to cool, then place them in a freezer-safe container and freeze for up to 3 months. Defrost in the fridge before reheating in an air fryer or hot oven.

      ❓ Frequently asked questions

      Is duck or goose fat better for roast potatoes?

      One isn't better than the other. Both fats have a high smoking point so they can be heated to quite high temperatures. They are therefore ideal for roasting potatoes, and both fats are tastier and richer in flavour than oil.

      What can I cook with duck fat?

      As well as roasting potatoes, duck fat can also be used for deep frying foods such as chips, french fries, calamari, and battered fish.
