Let’s talk about one of my favourite winter vegetables: the Jerusalem artichoke. No, not the big, spiky green globe artichoke, but its knobbly, potato-like cousin. These little tubers have a wonderfully unique, sweet, and nutty flavour that’s hard to pin down but utterly delicious. We’re taking this elegant ingredient, simmering it in a rich white wine sauce, and tucking it under a blanket of golden, flaky puff pastry. It feels a little rebellious to put something so special into a humble pie, but the result is pure, comforting magic. Let’s get cooking!
Ingredients
• (Serves 4)
• Juice of ½ lemon
• 1.4kg / 3 lbs Jerusalem artichokes
• 1 tbsp sunflower oil
• 1 large onion, finely chopped
• 2 garlic cloves, finely chopped
• 1 large potato, peeled and grated
• 400ml / 1 ¾ cups dry white wine, plus more if needed
• 1 small sprig of fresh thyme
• 400g / 14 oz shop-bought puff pastry
• Plain flour, for dusting
• 1 level tsp cornflour
• Sea salt and freshly ground black pepper, to taste
• Whole milk, for brushing
Instructions
1. Prepare a large bowl of cold water and squeeze in the juice of half a lemon. Peel the knobbly Jerusalem artichokes and drop them straight into the lemon water to prevent them from discolouring.
2. In a large saucepan, heat a splash of sunflower oil over a medium heat. Add the chopped onion, garlic, and grated potato. Fry until golden, scraping the bottom of the pan to lift any stuck bits – this adds colour and flavour.
3. Transfer the cooked onion mixture to a separate bowl. Add a little more oil to the pan. Drain the artichokes well and add them to the hot pan, stirring over a high heat until they are golden on all sides.
4. Return the onion mixture to the pan with the artichokes. Pour in the white wine, add the sprig of thyme, and top up with enough cold water to just cover the vegetables. Bring to a simmer and cook gently for 10–15 minutes, until the artichokes are tender when pierced with a knife.
5. Preheat your oven to 180°C / 160°C Fan / Gas Mark 4. Remove the thyme sprig and discard it. Using a slotted spoon, lift the vegetables out of the pan and divide them between four individual ovenproof pie dishes or one large pie dish.
6. Increase the heat under the saucepan to bring the remaining liquid to a boil. Let it bubble away and reduce by about half. This will concentrate the flavours beautifully.
7. While the sauce reduces, roll out your puff pastry on a lightly floured surface. Cut out lids slightly larger than your pie dishes to allow for shrinkage during baking.
8. Once the sauce has reduced, lower the heat. In a small bowl, mix the cornflour with a splash of cold water to form a smooth paste. Whisk this paste into the sauce; it will thicken very quickly. Season with salt and pepper, adding a splash more wine if it’s too thick.
9. Pour the thickened sauce over the vegetables in the pie dishes. Brush the rim of each dish with a little milk, then place the pastry lids on top, pressing the edges to seal. Brush the top of the pastry with more milk and cut a small steam vent in the centre of each pie.
10. Bake in the preheated oven until the pastry is risen and golden brown – about 10-15 minutes for small pies or 35–45 minutes for a large one. Serve immediately and enjoy.
Nutritional Information
• Nutritional Notes
• Jerusalem artichokes are a fantastic source of inulin, a prebiotic fibre that supports gut health. They are also rich in iron, which helps combat fatigue, and potassium, essential for heart health. This pie offers a hearty dose of comfort and nutrients in every bite!
Pro Tips
• To prevent Jerusalem artichokes from browning after peeling, immediately place them in a bowl of cold water with a squeeze of lemon juice.
• Don’t skip scraping the bottom of the pan when frying the onions and potatoes. Those browned bits, known as fond, add a huge depth of flavour to the final sauce.
• For an extra flaky pastry crust, ensure your puff pastry is very cold before rolling it out and placing it on the hot filling.
• Experiment with flavours! Swap the white wine for red and the thyme for a sprig of rosemary for a completely different, richer pie.
FAQ
Q: Can I make this Jerusalem artichoke pie vegan
A: Yes, you can. Use a vegan puff pastry, as many shop-bought varieties are made with oil instead of butter. For the pastry wash, simply swap the whole milk for a plant-based alternative like oat or soy milk. The filling itself is already dairy-free.
Q: How can I add more protein to this vegetarian pie
A: To make this a more protein-rich meal, you can add a can of drained cannellini beans or chickpeas to the filling along with the vegetables. Serving the pie with a side of green lentils or quinoa also effectively boosts the protein content.
Q: Can I prepare this pie ahead of time
A: Absolutely. The filling can be made up to two days in advance and stored in an airtight container in the refrigerator. When you are ready to eat, simply place the cold filling in your pie dish, top with the puff pastry, and bake as directed, adding a few extra minutes to the cooking time.
Q: What can I substitute for Jerusalem artichokes
A: While Jerusalem artichokes have a unique nutty flavour, you could substitute them with an equal amount of parsnips or celeriac for a delicious winter root vegetable pie. You may need to adjust the simmering time slightly to ensure the substitute vegetable is tender.
