James Martin fondant potatoes are a classic French-style side dish with crisp, golden edges and a soft, buttery centre. They are cooked slowly in stock and butter, which gives them a rich flavour and luxurious texture. This recipe is straightforward rather than difficult, but it rewards a little patience and care. From start to finish, it takes about 45 minutes.
Ingredients
For the potatoes
- 6 large Maris Piper or King Edward potatoes
- 40g unsalted butter
- 2 tbsp olive oil
- 2 garlic cloves, lightly crushed
- 2 sprigs fresh thyme or rosemary
- 300ml hot chicken or vegetable stock
- Salt, to taste
- Freshly ground black pepper

How to Make James Martin Fondant Potatoes
- Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the potatoes cook evenly.
- Prepare the potatoes: Peel the potatoes and trim the ends so they sit flat. Cut each potato in half lengthways and season both sides with salt and pepper.
- Brown the potatoes: Heat the olive oil and butter in a large ovenproof frying pan over medium heat. Place the potatoes cut side down and cook for 5 to 7 minutes until deeply golden.
- Add flavour: Turn the potatoes over, then add the garlic and herbs to the pan. Let them cook for 1 minute so the flavours release into the butter.
- Add the stock: Carefully pour in the hot stock so it comes halfway up the potatoes. Bring to a gentle simmer.
- Bake: Transfer the pan to the oven and bake uncovered for 25 to 30 minutes, basting once or twice, until the potatoes are tender and the liquid has reduced.
- Rest and serve: Remove from the oven and let the potatoes rest for 5 minutes. Spoon over the buttery juices before serving.
Tips
Why are my fondant potatoes not crispy?
The pan needs to be hot enough when you first brown the potatoes. Do not move them too early, as this prevents a good crust from forming.
Can I make these without an ovenproof pan?
You can transfer the potatoes and liquid to a snug baking dish after browning, then continue cooking in the oven.
How do I stop the potatoes from falling apart?
Use floury potatoes and handle them gently when turning. Cutting clean, flat edges also helps them keep their shape.
Serving Suggestions
- Serve with roast chicken, beef, or lamb
- Pair with pan-fried fish and greens
- Add as a side to a vegetarian mushroom dish
Storage
Room temperature
Fondant potatoes should not be kept at room temperature for more than 2 hours.
Refrigerator
Store leftovers in an airtight container in the fridge for up to 2 days. Reheat gently in the oven with a splash of stock.
Freezing
Freezing is not recommended, as the texture becomes grainy once thawed.

FAQs
What potatoes are best for fondant potatoes?
Floury potatoes like Maris Piper or King Edward work best because they absorb the stock and butter while staying tender inside.
Can I make fondant potatoes in advance?
They are best served fresh, but you can part-cook them and finish in the oven just before serving.
Can I use vegetable stock instead of chicken stock?
Yes, vegetable stock works very well and keeps the dish suitable for vegetarians.
Why is my stock not reducing?
The oven may be too cool or the pan too large. Increase the temperature slightly and use a snug pan so the liquid reduces properly.
