Potato gnocchi by chef Béatriz Gonzalez using our professional masher

To test our Prep Chef masher, chef Béatriz Gonzalez decided to make potato gnocchi with parmesan cream and chestnut crisps.



1kg mashed potato
400g flour
30g creamed butter
50g parmesan
1 egg

parmesan cream

200g single cream
50g parmesan
Zest of 1 lemon
Half a lemon juice

chestnut crisps

100g roasted chestnuts

To make the gnocchi

Wrap the unpeeled potatoes in aluminium foil.
Place them on a bed of coarsely ground salt in a gastronorm pan.
Bake them for 1 hour at 170°C (340°F).
The salt will absorb all the moisture, drying out the potato middles and making them easier to work with.

Peel the potatoes and put them in the Prep Chef with its puree-making accessory attached. This device’s fine mesh and ergonomics effortlessly provide airier mash three times quicker.

With the Prep Chef masher, you can mash potatoes with a single movement. Its legs give it stability, making it very easy to use. This kitchen accessory is designed to make your teams work faster and be more productive when making purées. A product made in France that guarantees quality in use and results.

Put the resulting mash in a saucepan over a moderate heat to dry it out.
Add the creamed butter to soften the mash and cool it down slightly.
Take the pan off the heat and incorporate the egg and parmesan. Season and add the flour using an Exoglass® spatula.
Use the Exoglass® scraper to remove the mixture from the pan. The scraper’s flexible material allows you to get every bit of mash.

Use a fork to make the gnocchi.

To make the parmesan cream

Bring 200g of 30% fat crème fraîche to the boil.
Add 50g of grated parmesan, salt and pepper.
Once the cream has thoroughly absorbed the parmesan, add the zest of 1 lemon, which you have grated using a Microplane grater.
Leave it to cook on a low heat and add the juice of half a lemon, which will thicken your sauce.
Filter the mix out using an Exoglass® colander until it is completely smooth.

Chef’s tip

In order to know exactly how much zest to grate, hold your Microplane upside down. This way you can see how much more you need.

To cook the gnocchi

Bring a large pan of salted water to boil, then put in the gnocchi until they rise to the surface. Use a Skim’all to drain them, then cover them in ice water.

To make the chestnut crisps

Finely grind the chestnuts in a blender, then spread out the resulting paste on a baking tray covered with a Silpat mat.
Bake for about 30 minutes at 70°C (160°F).


Heat up the gnocchi in the sauce, put them in the centre of the plate, add the chestnut chips and a ribbon of crème de parmesan, and finish off with a few parmesan shavings.


The Prep Chef is ideal for making the mashed potato, as its stability is better and it’s three times quicker than a grinder. In one swoop you get airier puree.
The Prep Chef can produce all types of mash with all sorts of potatoes. Sweet potatoes or vitelotte potatoes can be added to ordinary potatoes for more originality. To heighten the flavour, you can add a pinch of grated nutmeg.
You can also try purées instead of mashed potatoes – sweet potato, for example. Try offbeat spices and herbs to surprise the taste buds.
And if you’re really attached to potato, you can also make mash with different potato varieties. For amethyst-coloured mash, choose vitelotte, a violet-coloured variety.

The Exoglass® spatula is perfect for mixing hot preparations or incorporating flour or eggs, as I do here. It’s handy and hard-wearing.
In the same product range, you can also try the Prep Chef multi-cut cutter, which can cut up all sorts of fruits, vegetables and cheeses.

High-quality kitchen utensils to ease the labour-intensive tasks are essential for certain dishes. Matfer offers kitchen utensils for all your needs, together with safe blade storage.

The scraper is ideal for getting out every last bit of your mixture.
