Fondant potatoes are like boss level spuds, seared barrels of potato are seared then gently cooked, almost confit style in butter & stock.
Despite their reputation for being difficult, taking your time and not rushing results in perfectly cooked buttery and soft potatoes every time!
Classic French Potato Fondant
Cooking shows that play the game of food as sport are littered with failed fondant potatoes.
So much so that you would think that they are difficult to make, but they are not, they are easy, but you cannot cheat or rush.
They are for me the undisputed heavyweight champion of the potato side dish division.
But these luxurious buttery soft potatoes trump them all!
They are essentially nothing more than seared potatoes poached in butter and stock.
The name fondant indicates their french origin and it is a word that means melting, which tells you all that you need to know about the texture.
Frequently Asked Questions
Do the type of potatoes matter?
Yes, enormously! If you try and make these with waxy potatoes you will be deeply disappointed, it just does not work.
You want a floury or mealy potato, something like a King Edwards or Maris Piper. If you are in the US grab a Russet spud and off you go!
There is no salt in the recipe, is that right?
Yes, I use salted butter for practically everything and combining this with stock means that slat is not required. That of course does not mean that you cannot add more if you wish.
Can I use other herbs?
Yes, although thyme is my favourite. Rosemary or tarragon are other good options.
Can I use a lid rather than baking parchment?
No! The lid does not permit enough evaporation. You want the water to slowly evaporate allowing the bottom of the potatoes to sit in almost pure butter at the end of the cooking process.
The best way to make the paper cartouche is to cut a square of baking parchment around 50% larger than your saucepan. Then get all origami on it.
Fold it in half, to a rectangle, then in half again to form a square, then into a triangle. Then keep folding that triangle smaller by folding it in on itself making a long thing triangle.
Finally, grab some scissors, cut the tip of the triangle off (5mm or ⅕”), then cut the triangle into a length that is just over half of the diameter of the saucepan. Unfold and you have a circle (ish) with a hole in the middle.
Can I use a frying pan?
Not really, a frying pan allows the liquid to evaporate too quickly and risks not cooking the potatoes.
The question is really what cant you serve fondant potatoes with and as far as I am concerned that list is short… To be fair, I’d happily eat them with my cornflakes!
Whilst they are deceptively easy to cook they are seriously indulgent, so I tend to keep them for special treat meals.
Fondant potatoes are the most indulgent potato side dish, barrels of spud slowly poached in a brown butter and stock mix, the perfect side for a special meal.
- 2 Large Floury Potatoes
- 1 Tbsp Cooking Oil
- 125g (8 Tbsp) Butter
- 1 Sprig Fresh Thyme
- 250ml (1 Cup) Vegetable Stock
- Lay the potato on the table and cut it into a thick slice approximately 30mm (1¼-1½") thick.
- Using a 50mm (2") cookie cutter or aluminium form cut out four barrels of potato, you may need to use more potatoes if yours are small.
- Using a potato peeler form a 3-5mm chamfer (an angled cut) around the edge of the potato barrels both top and bottom.
- Heat the cooking oil over a medium high heat in a medium (24cm 9-10") saucepan.
- Sear the top of the potatoes until they are a deep golden colour in the oil, this should take between 3 and 5 minutes.
- Flip over the potatoes and then add in the butter and sprig of thyme, cook the potatoes for 5 minutes in the butter. The butter should begin to brown during this period.
- Remove from the heat and pour in the vegetable stock, do this carefully the butter will foam a lot when you begin.
- Return to the heat and reduce it to medium low.
- Cover the potatoes with a piece of baking parchment that is wet and has a small hole cut in the middle (a cartouche).
- Simmer the potatoes for 35-40 minutes.
