This versatile potato and Fontina tart is inspired by the cuisine of Valle d’Aosta – the tiny Italian region tucked into the corner of the Alps where Italy, Switzerland and France meet. Valle d’Aosta sits on the route between my Swiss food and wine tour and Emilia-Romagna tour, so I often stop there for lunch and have come to love its unique mountain cuisine. This tart is delicious as a vegetarian dish – starring the cheese and potatoes – but smoked freshwater fish is another classic Valle d’Aosta ingredient and I often add some hot-smoked trout. Potatoes and smoked fish are such natural partners that any smoked fish, or even eel, makes a delicious addition for a pescatarian version of this tasty tart. Fontina is one of the great northern Italian cheeses; if it’s not available, use any mild washed rind cheese. I’ve even substituted smoked stretched-curd cheese to make a potato and scamorza tart. Use a good all-butter puff pastry, like Carême in Australia (which is already the right dimensions) and a naturally cultured crème fraîche. I like to serve this potato and Fontina tart with a textured Rosé de Provence such as La Chapelle Gordonne from the Vranken Pommery stable.

Serves 2–4

Ingredients
  • 1 x 375g butter puff pastry sheet (13oz)
  • 150g hot-smoked rainbow trout or eel meat, flaked (5½oz)

  • 1 small brown onion, very finely sliced
  • ¼ cup crème fraîche (60ml)

Method
  1. Place a baking tray in the oven and preheat to 200°C (400°F).
  2. Place pastry on a sheet of baking paper and, if necessary, gently roll out to 27cm x 36cm (10½ x 14″).
  3. Place trout, potato, onion, crème fraîche, caraway, salt and pepper in a large bowl.
  4. Using your hands, toss together to combine well.
  5. Spread in an even layer over the pastry leaving a 5cm (2″) border and ensuring the potato slices aren’t stuck together.
  6. Top with cheese.
  7. Fold the edges of the pastry up to partially enclose the filling.
  8. Brush well with egg.

Valle d’Aosta FAQ

Where is Valle d’Aosta? What is Valle d’Aosta?

Valle d’Aosta is Italy’s smallest and least populated region — a high Alpine valley tucked into the north-western corner of Italy where the borders of Italy, France and Switzerland meet.

It sits at the foot of the highest peaks in the Alps, including Mont Blanc, the Matterhorn and Monte Rosa.

The valley’s ancient connection with Switzerland runs through the Great Saint Bernard Pass — at 2,469m (8,100′), one of the highest road passes in the Alps, used since prehistoric times as a route between Martigny in the Swiss canton of Valais and Aosta. At the summit, the Great Saint Bernard Hospice — founded in 1049 and still operating today — once sheltered travellers crossing the pass, and gave its name to the famous rescue dogs bred there.

Today most traffic takes the Great Saint Bernard Tunnel beneath the pass, opened in 1964, though the road over the top remains one of the most dramatic Alpine drives when it’s open in summer.

What is Fontina?

Fontina is a semi-soft, washed-rind cheese made exclusively in Valle d’Aosta from the raw whole milk of Valdostana cattle.

It has Protected Designation of Origin (DOP) status, meaning only cheese made in the valley to strict traditional methods can carry the name.

Genuine Fontina DOP has a thin, pale orange-brown rind and a supple, mildly nutty interior that melts beautifully.

It is the key ingredient in fonduta, the Valle d’Aosta version of fondue.

What is Valle d’Aosta cuisine known for?

Valle d’Aosta has a distinctive mountain cuisine shaped by its Alpine environment and its position at the crossroads of Italian, French and Swiss culinary traditions.

Its most celebrated products are Fontina DOP cheese and Lard d’Arnad DOP — a cured fatback spiced with rosemary, sage and mountain herbs.

Smoked freshwater fish, polenta, chestnuts, wild mushrooms and game also feature prominently, along with the valley’s own red wines made from local varieties such as petit rouge and cornalin.

Switzerland with Roberta was all I hoped and expected – she takes control of all the things I no longer want to decide. Roberta plans the itinerary to such an amazing extent – the food choices and venues always showcase the region we’re in and never disappoint. The small group works extremely well, with enough downtime to do your own thing but beautifully combined with an itinerary which encompasses all the things you want to see and more. My trip to Switzerland was my second adventure with Roberta – my first was Emilia-Romagna and I’ve already booked my next one to Scotland.

I had such a blast on the Swiss food and wine tour with Roberta. As a solo traveller, I loved the friendly small group vibe and the fact that all meals and transport were taken care of. I got to explore amazing villages and wineries and cheese producers that I would have missed if I'd been travelling on my own. It was so much fun that I've already booked my next tour with Roberta.

Thank you Roberta for organising such a wonderful Swiss tour! It felt like going from gem to gem – and your knowledge and passion for the places we visited and the people you introduced us to was evident throughout. Starting in the most charming village and finishing at such a grand and beautiful location, I remember thinking at our farewell lunch: “it doesn’t get much better than this!” Thank you, and I am already looking forward to my next trip with you.

My husband and I had never travelled in Switzerland before, and we were so glad we chose Roberta to show us ‘Her Switzerland’. Roberta's knowledge, enthusiasm and passion for food and wine made every day an adventure. Every meal was a delicious, interesting experience where we learnt a lot about Swiss foods and wines, which were truly excellent. One of the many highlights was mushroom foraging in an Emmental forest then joining our local fungi expert in her home for lunch. Roberta's ability to scout unique accommodation and experiences truly made for a trip we will never forget.
