My lovely friend Sammy Jo told me about this idea and I’ve been making these potatoes ever since. A roast potato is a wonderful thing, in fact a spud is a wondrous thing in general when you think of its versatility – chips, dauphinoise, gratin, sauté, jacket. My mate Julian wants to open potato world with rides and merchandise, but he’s bonkers. Marmite roasts, though? Now we’re talking!

Serves 4-6
Prep time: 15 min
Cook time: 1 h 10 min
Total time: 1 h 25 min


4 tbsp olive oil
1.5kg Maris Piper potatoes, peeled and quartered
3 tbsp Marmite


1. Preheat the oven to 180°C/fan 160°C/gas 4. Pour 3 tablespoons of the oil into a large roasting tray and put it in the oven to heat up while you cook the potatoes.

2. Bring a large pan of salted water to the boil and cook the potatoes for 7–8 minutes. Drain them through a colander and toss roughly to fluff up the outsides of the potatoes, then allow them to stream dry for a few minutes. Tip the potatoes into the tray with the hot oil, toss gently in the oil and roast for 40 minutes.

3. Turn up the oven temperature to 200°C/fan 180°C/gas 6. In a bowl, combine the remaining 1 tablespoon of oil with the Marmite and gently whisk together with a fork. Pull the cooked potatoes out of the oven and toss with the Marmite mixture, then return to the oven for a final 15–20 minutes until they are crispy.
