Truffle Oil & Sea Salt Roast Potatoes Recipe
Introduction
These truffle oil and sea salt roast potatoes elevate a classic side dish with a luxurious aroma and perfect crunch. Crisp on the outside and fluffy on the inside, they make a wonderful addition to any meal.

Ingredients
- 1.5kg Maris Piper potatoes, cut into even-sized pieces
- 2 tbsp fine semolina (optional, but adds extra crunch)
- 5 tbsp goose fat or vegetable oil
- 2-3 tsp truffle oil
- Pinch of sea salt flakes
- 2-3 tbsp finely chopped parsley
Instructions
- Step 1: Put the potatoes in a large pan of cold salted water and bring to the boil. Simmer for 8-10 minutes until just tender on the outside. Drain them and leave to steam-dry for 5 minutes.
- Step 2: Shake the colander to rough up the edges of the potatoes. If using semolina, sprinkle it over the potatoes and toss to coat evenly.
- Step 3: Preheat the oven to 220°C (200°C fan)/gas mark 7. Pour the goose fat or vegetable oil into a roasting tin and place it in the oven to heat for at least 10 minutes.
- Step 4: Carefully tip the potatoes into the hot fat and gently turn them to coat thoroughly. Roast for 1 hour to 1 hour 10 minutes, turning halfway through, until golden and crisp.
- Step 5: Remove from the oven, drizzle over the truffle oil, and season with sea salt flakes. Stir through the chopped parsley just before serving.
Tips & Variations
- For extra flavor, toss the potatoes with garlic cloves or rosemary before roasting.
- Using goose fat will give richer taste, but vegetable oil works well for a vegetarian option.
- Fine semolina is optional but helps create a crunchier crust on the potatoes.
- Adjust the amount of truffle oil to suit your taste; start with less and add more if desired.
Storage
Store any leftover roast potatoes in an airtight container in the refrigerator for up to 2 days. Reheat them in a hot oven or air fryer to help restore the crisp texture. Avoid microwaving as it can make the potatoes soggy.

Ingredients
Potatoes
- 1.5kg Maris Piper potatoes, cut into even-sized pieces
- 2 tbsp fine semolina (optional, but adds extra crunch)
- 5 tbsp goose fat or vegetable oil
Finishing & Garnish
- 2–3 tsp truffle oil
- pinch of sea salt flakes
- 2–3 tbsp finely chopped parsley
Instructions
- Parboil the potatoes: Place the cut potatoes into a large pan of cold salted water and bring to a boil. Simmer gently for 8-10 minutes until they are just tender on the outside but still firm inside.
- Drain and steam-dry: Drain the potatoes and leave them to steam-dry in the colander for 5 minutes. Then shake the colander vigorously to roughen up the edges of the potatoes, which helps create a crispy crust when roasted.
- Coat with semolina (optional): If using, sprinkle the fine semolina over the roughened potatoes and toss gently to coat evenly.
- Preheat the roasting fat: Heat your oven to 220°C (200°C fan)/Gas mark 7. Place the goose fat or vegetable oil in a roasting tin and put it in the oven for at least 10 minutes to get very hot.
- Roast the potatoes: Carefully tip the potatoes into the hot fat in the roasting tin, turning gently to coat them fully. Roast for 1 hour to 1 hour and 10 minutes, turning the potatoes halfway through to ensure even golden crispiness.
- Finish and serve: Once roasted to golden perfection, drizzle the truffle oil over the potatoes and season with a pinch of sea salt flakes. Toss with the chopped parsley to add freshness and serve immediately.
Notes
- Using goose fat adds a richer flavor, but vegetable oil is a suitable vegetarian alternative.
- Roughening the potatoes after parboiling improves crispiness during roasting.
- Fine semolina is optional but gives an extra crunchy texture to the potato surface.
- Adjust the amount of truffle oil to taste, as it is quite potent.
- For best results, use Maris Piper potatoes or other floury varieties ideal for roasting.
