Curtis Stone reveals the secret to ultimate crispy roast potatoes (2024)

One of the reasons why we love potatoes so much is because they might just be the most versatile veggie ever. Mashed, fried, boiled, steamed; there’s nothing they can’t do!

When the festive season comes around, we think the best way to enjoy them is roasted – but we’ve all experienced the struggle of mastering the perfect roast potatoes. You know, the whole crispy-on-the-outside-fluffy-on-the-inside kinda vibe. So, we asked Curtis Stone (the Christmas feast expert) how to create the ultimate roast potatoes every single time, and he shared some of his no-fail secrets with us.

How do you get crispy roast potatoes? Curtis Stone answers:

Achieving the ultimate crispy roasted potatoes comes down to a few key steps, according to Curtis. First things first, it’s important to not overcrowd the tray, with Curtis saying: “you can’t put too many potatoes in the tray because they will steam. You want them to be dry, and that’s how you get them crispy on the outside, fluffy on the inside.”

Another trick to scoring that golden crunch on your spuds is the amount of oil used: “you need a lot of oil, and lay the potatoes on a non-stick tray or on top of baking paper.” Lots of oil… noted!

And lastly, Curtis revealed an unexpected trick that will ensure maximised crunch, saying that: “they need to be cut so there’s more surface area. This will give you more corners.” More corners equals more spots for crispiness!

Now that you know all the ins and outs of roasted potatoes, it’s time to get your carb on this Christmas with Curtis’ fool-proof recipe.

Curtis Stone’s ultimate roasted potatoes

Curtis Stone reveals the secret to ultimate crispy roast potatoes (1)

Ingredients

  • 1.5kg Red Royale potatoes, peeled, halved lengthways, then cut on sharp diagonal (each piece should be about 5cm)
  • 1/4 cup (60ml) olive oil
  • 60g butter, chopped
  • 6 sprigs rosemary
  • 6 garlic cloves, peeled
  • 2 tbsp finely chopped fresh flat-leaf parsley

Method

Step 1: Preheat oven to 230C (210C fan-forced). Place a large heavy rimmed baking tray on bottom rack of oven while preheating.

Step 2: Place potatoes in a large pot of salted water and bring to a boil. Reduce heat to a simmer and simmer for 8 mins, or until potatoes are completely tender but not breaking apart. Drain potatoes into heatproof colander and place colander over pot. Place over low heat for 1 min to allow steam to evaporate.

Step 3: In a large bowl, toss drained potatoes with oil and season with 3 tsp salt (outside of potato pieces will break up some at this point – that is fine). Transfer potatoes to preheated baking tray, spreading potatoes in an even layer. Roast potatoes, without turning, for 30 mins. Continue roasting, turning occasionally, for 20-25 mins or until potatoes are crisp all over. Scatter butter , rosemary and garlic all around potatoes and shake pan to toss with potatoes. Roast for 10 mins longer.

Step 4: Remove potatoes from oven and toss with parsley . Season potatoes with salt and pepper. Transfer to a platter and serve.

Do you need to boil potatoes before roasting?

Boiling potatoes a little before roasting will help with achieving that golden, crispy exterior. It will help the oil get into the little cracks of the potatoes, giving it that extra crunch factor.

Which oil is best for roasted potatoes?

Any oil with a high smoke point is perfect for roasting potatoes. Think avocado oil, almond oil, canola oil, grapeseed oil, peanut oil, sesame oil and sunflower oil; they’ll all work great!
