I love all the spring tart recipes that pop up this time of year, ushering away all the heavier menu items that came before them in winter and fall. Trouble is, most of them include cheese. And I hate cheesy tarts.
Now, as a general rule, I don't mind cheese (well, at least not the mild ones like young cheddar and mozzarella, or good Parmesan). But I must admit being one of those people who could easily live without the stuff.
So one day where a flaky spring tart seemed to me the only appropriate thing to eat, I improvised this one. It was so good that's I've been making it on an annual basis ever since.

a flaky allium and new potato tart with sesame-sprinkled pastry
serves 3
INGREDIENTS
• 3 pre-made puff pastry sheets (you can of course make your own pastry, but this is a relatively quick recipe), 1 per tart • 2 large onions • 6-8 shallots • 2 large bay leaves
• 1 leek • 8 garlic cloves, or about half a bulb • enough green onions to have 6 shoots (the green tops) • a kettle-full with approx. 500 mL of just-boiled water, or approx. 500 mL of vegetable stock* • 1-2 tsp stock powder or 1/2 a bouillon cube* • 2 small oblong potatoes, or 3-4 small round ones • 1 Tbsp fresh thyme, plus more for garnish • 1 tsp dried herbes de Provence or similar herb blend, plus more for finishing • sesame seeds • olive oil • salt • pepper
*for reference, I used a combination of water from the kettle and stock powder, but if you are using liquid vegetable stock instead, just add it in whenever the recipe calls for water and ignore the part when it calls for the stock powder / bouillon cube
PREPARATION
1. Remove your pastry sheets from the freezer and place them on a baking tray lined with parchment paper to thaw.
2. Peel and thinly slice your onions from root to shoot, then place them in a large pan on medium-low heat with a glug of olive oil and a small pinch of salt. We just want them to soften and sweeten, not fry, so gently stir in a splash of water from your kettle any time you hear them begin to sizzle, if you see them start to colour, or if some of them begin to catch on the bottom of the pan.
3. In the meantime, peel and quarter your shallots lengthwise. Add them to the pan with the bay leaves, giving everything a little stir and topping up with a splash more of water if necessary.
4. Peel the garlic cloves and clean the leek well. Keep the garlic cloves whole, and cut the leek across its width into thin slices. Add the garlic and the white part of the leek to the pan, reserving the leek greens for later. If using the whites of your green onions, thinly slice them now and add them in at this step (I keep my green onions in water so I can re-grow them, hence do not use the whites). Let cook for 3-4 minutes, stirring occasionally and adding more water again if the bottom of the pan gets dry.
5. Add the stock powder or bouillon cube, fresh thyme, dried herbs, a bit of salt and pepper, and the green part of the leek. Stir again to combine. Top up with enough water to generously cover the bottom of the pan, then turn the heat up to medium-high so the liquid can evaporate and the alliums can finish softening through.
6. While the alliums finish cooking, slice your cleaned potatoes lengthwise as thinly as you can.
7. Once the alliums are done, fish out the bay leaves. Then, remove 1/3 of the alliums from the pan and blitz into a purée with the help of an immersion blender.
8. With a sharp knife, draw a border (about as wide as the tip of your thumb) parallel to the edges of each pastry sheet. You want to lightly pierce the top layer without cutting through the pastry entirely. Then, prick all over the middle portion of each pastry sheet with a fork. This will prevent the center from rising during baking, all while the outer frame is free to puff up.
9. Avoiding the outer frame, spread even amounts of the allium purée onto each pastry sheet. Then layer on the sliced potatoes, overlapping them slightly, and cover with any leftover purée. Finish by topping the tarts with the unpuréed alliums from the pan, followed by two green onion tops each.
10. Brush the pastry edges with water and sprinkle on enough sesame seeds to cover. Add a bit more fresh thyme and a faint drizzle of olive oil all over the tarts.
11. Bake in the middle of the oven at 200°C fan / 220°C / 430°F until the edges have puffed up and are golden, around 20 minutes or so (check the package your pastry came in or the pastry recipe you followed).
12. Remove from the oven, sprinkle with a smidge more herbs (fresh and/or dried, you decide) and some flaky sea salt. Enjoy! |
