📝 About This Recipe

Hailing from the rugged mountains of Piedmont, this dish celebrates Castelmagno DOP, a rare and ancient semi-hard cheese known for its complex, herbal, and slightly sharp profile. These pillows of handmade potato gnocchi are bathed in a velvety cream sauce that allows the distinctive character of the cheese to shine. Finished with crunchy toasted hazelnuts and a drizzle of wildflower honey, it is a sophisticated symphony of textures and flavors that embodies the soul of Northern Italian Alpine cuisine.

🥗 Ingredients

For the Gnocchi

  • 1 kg Russet or Yukon Gold potatoes (starchy varieties work best)
  • 250-300 grams Tipo 00 flour (plus extra for dusting)
  • 1 large Egg (lightly beaten)
  • 1 pinch Fine sea salt
  • 1 pinch Nutmeg (freshly grated)

For the Castelmagno Sauce

  • 200 grams Castelmagno DOP cheese (crumbled by hand)
  • 200 ml Heavy cream
  • 50 ml Whole milk
  • 30 grams Unsalted butter (high quality)
  • 1 pinch Black pepper (freshly cracked)

For Finishing and Garnish

  • 50 grams Piedmontese Hazelnuts (Tonda Gentile) (toasted and roughly chopped)
  • 1 teaspoon Wildflower honey (optional, for drizzling)
  • 4-5 leaves Fresh sage leaves (fried in butter until crisp)

👨‍🍳 Instructions

  1. 1

    Place the whole, unpeeled potatoes in a large pot of cold salted water. Bring to a boil and simmer for about 25-30 minutes until fork-tender.

  2. 2

    Drain the potatoes and peel them while they are still hot (use a clean kitchen towel to hold them). Pass them through a potato ricer onto a clean wooden work surface, spreading them out to let the steam escape.

  3. 3

    Once the potatoes have cooled slightly but are still warm, sprinkle with a pinch of salt, nutmeg, and about 200g of the flour. Create a well in the center and add the beaten egg.

  4. 4

    Gently incorporate the flour and egg into the potatoes using a bench scraper or your hands. Knead lightly just until a soft, non-sticky dough forms. Avoid overworking, or the gnocchi will become tough.

  5. 5

    Divide the dough into 4 pieces. Roll each piece into a long rope about 1.5 cm thick. Use a knife to cut the ropes into 2 cm nuggets.

  6. 6

    Optional: Roll each nugget over a gnocchi board or the tines of a fork to create ridges, which will help hold the sauce. Place them on a tray dusted with flour.

  7. 7

    Bring a large pot of water to a boil and add a generous amount of salt.

  8. 8

    In a large, wide skillet, combine the heavy cream and milk over low heat. Bring to a very gentle simmer.

  9. 9

    Slowly add 150g of the crumbled Castelmagno cheese and the butter to the skillet. Whisk constantly until the cheese has melted into a smooth, thick fonduta. Keep warm on the lowest setting.

  10. 10

    Drop the gnocchi into the boiling water in batches. As soon as they float to the surface (usually 1-2 minutes), use a slotted spoon to transfer them directly into the skillet with the cheese sauce.

  11. 11

    Gently toss the gnocchi in the sauce for 30 seconds, adding a tablespoon of pasta water if the sauce needs loosening to coat perfectly.

  12. 12

    Remove from heat. Plate the gnocchi immediately, topping with the remaining 50g of crumbled Castelmagno, the toasted hazelnuts, and a crack of black pepper.

💡 Chef's Tips

Always peel and rice the potatoes while hot to ensure a light, airy texture. Use the 'Tipo 00' flour sparingly; the less flour you use, the more delicate the gnocchi will be. If you cannot find Castelmagno, a mix of sharp Gorgonzola Piccante and aged Parmigiano Reggiano can be a substitute, though the flavor profile will change. To toast hazelnuts, place them in a 180°C (350°F) oven for 8-10 minutes until fragrant and the skins start to crack. Never let the cheese sauce reach a rolling boil, or the fats may separate and become oily.

🍽️ Serving Suggestions

Pair this rich dish with a full-bodied Piedmontese red wine like a Barolo or Barbaresco to cut through the creaminess. Serve alongside a simple arugula salad with a lemon vinaigrette to provide a fresh, acidic contrast. A side of honey-glazed roasted root vegetables complements the earthy tones of the cheese. For a truly decadent touch, shave fresh white truffles over the top if they are in season. Finish the meal with a light pear sorbet to cleanse the palate.
