Prep Time: 15 minutes
Cook Time: 1 hour 30 minutes
Total Time: 1 hour 45 minutes

Ingredients

  • 2 kg Maris Piper potatoes, peeled and cut into halves or quarters
  • 5 tbsp olive oil (2–3 tbsp for the tray + extra for drizzling)
  • 4 sprigs fresh rosemary (can swap for thyme)
  • Salt, to taste

Step-by-Step Instructions

  1. Prep the potatoes and oven
    • Preheat your oven to 200°C (390°F).
    • Peel the Maris Piper potatoes and cut them in half or into quarters, aiming for evenly sized pieces so they roast at the same rate.
  2. Parboil with rosemary
    • Place the potatoes into a large pot and cover with lukewarm water.
    • Add the 4 sprigs of fresh rosemary and a good pinch of salt.
    • Bring to the boil, then reduce to a gentle boil and parboil for about 12 minutes.
    • Check doneness by poking a potato with a sharp knife: it should meet a little resistance. If it slides through too easily, they’re over-boiled; if you can’t get it in, they need more time.
  3. Preheat the roasting oil
    • While the potatoes are parboiling, pour 2–3 tablespoons of olive oil into a large baking dish or roasting tray.
    • Place the tray in the hot oven so the oil becomes very hot – this helps the potatoes sizzle on contact and crisp up beautifully.
  4. Rough up the potatoes (for extra crispiness)
    • Drain the potatoes in a colander, removing the rosemary stems but keeping as many rosemary leaves as possible with the potatoes.
    • Return the potatoes to the empty pot, put the lid on, and gently shake the pot a couple of times.
    • The edges should look slightly fluffy and roughed up – this texture is what creates a crunchy crust in the oven.
  5. Start roasting
    • Carefully remove the hot baking dish from the oven.
    • Tip the potatoes into the tray – you should hear a sizzle as they hit the hot oil.
    • Drizzle over more olive oil (enough to lightly coat the tops), scatter over the rosemary leaves, and add a generous pinch of salt.
    • Spread the potatoes out as much as possible so each piece has some space.
    • Roast for 45 minutes.
  6. Turn and finish roasting
    • After 45 minutes, take the tray out and turn each potato so another side can crisp up.
    • Return the tray to the oven and roast for another 45 minutes, or until the potatoes are golden, crispy, and deeply browned in spots.
  7. Season and serve
    • Taste and add more salt if needed.
    • Serve immediately as a side with Christmas dinner, Sunday roast, or any cosy meal.

Pro Tips

  • Don’t skip the “shake” step: Roughing up the potatoes after parboiling is key for crispy rosemary roast potatoes – the fluffy edges become golden and crunchy in the oven.
  • Get the oil properly hot: Preheating the oil in the tray ensures an instant sizzle, which helps prevent sticking and boosts crispiness.
  • Make ahead: You can parboil and rough up the potatoes a day or two in advance. Store them covered in the fridge, then roast as directed on the day for stress-free Christmas or Sunday roast prep.
