  • 2 egg yolks

  • 60 g (½ cup) finely grated Parmesan cheese

  • Salt & freshly ground black pepper

For the Roquefort Cream Sauce

  • 1 tbsp unsalted butter

  • ½ onion, finely minced

  • 1 garlic clove, minced

  • 120 ml (½ cup) heavy cream

  • 50 g (2 oz) Roquefort cheese, crumbled

  • Fresh rosemary leaves, finely chopped

🍳 Step-by-Step Instructions

1️⃣ Prepare the Sweet Potato Purée

Roast the sweet potatoes until completely soft. Let them cool slightly, then peel and mash until very smooth.
For the silkiest texture, pass the purée through a sieve or blend briefly. Allow it to cool completely before making the dough.

2️⃣ Make the Gnocchi Dough

In a large bowl, combine the sweet potato purée, egg yolks, Parmesan, salt, and black pepper.
Gradually add the flour, mixing gently until smooth. The dough should be soft and sticky, not firm — it should hold its shape but still pipe easily.

Transfer the dough to a piping bag and cut off the tip to create an opening about 1.5 cm (½ inch) wide.

3️⃣ Cook the Gnocchi

Bring a large pot of well-salted water to a gentle boil.
Pipe small pieces of dough directly into the water, cutting them with scissors or a knife as they drop in.

Once the gnocchi float to the surface (about 1–2 minutes), they’re done. Remove gently and set aside.

4️⃣ Prepare the Roquefort Cream Sauce

Melt the butter in a skillet over medium heat. Add the onion and garlic and sauté until soft and fragrant.
Stir in the rosemary and black pepper, then pour in the cream.

Add the crumbled Roquefort and stir gently until fully melted and creamy. Finish with a light drizzle of balsamic glaze. Taste and adjust seasoning — the sauce should be rich, salty, and slightly sweet.

5️⃣ Combine & Finish

Gently toss the cooked gnocchi in the Roquefort cream sauce until evenly coated.
Top with toasted walnuts, fresh parsley, and extra Parmesan. Serve immediately while warm and creamy.

📌 FAQs

Can I make the gnocchi dough ahead of time?
Yes! Keep the dough refrigerated in the piping bag for up to 12 hours.

Can I freeze the gnocchi?
Absolutely. Pipe them onto a tray, freeze until solid, then store in a freezer bag. Cook straight from frozen.

What can I substitute for Roquefort?
Gorgonzola or blue cheese work beautifully. For a milder option, try creamy goat cheese.

How do I know if the dough has enough flour?
It should be soft and slightly sticky but able to hold shape when piped. Add flour a tablespoon at a time if needed.
