Onion tart with apples, bacon & Comté Cheese
At a recent Comté cooking class, we used this fabulous artisanal French PDO cheese to make a simple onion tart. The recipe uses caramelised onions, cheese, apples and bacon which comes together in the perfect combination of crispy, savoury and sweet. You can either make your own rough puff pastry or just use a good ready frozen, all butter puff pastry.
You can either make a big tray and cut it into pieces or make individual tarts if you prefer. It is best served hot, just out of the oven when the cheese is still melting the pastry is just crisp. Your kitchen will smell amazing from the combination of the frying bacon and the baking pastry.
Rough puff pastry covered with sweet, stewed onions, apples and bacon, strewn with Comté, then baked until golden and bubbling. You can cheat and buy puff pastry, but this ‘rough puff’ version is really easy and definitely worth a try!
Onion tart with apples, bacon & Comté Cheese
Ingredients
For the pastry
- 250 g strong white plain flour plus extra for dusting
- 1 ⁄2 teaspoon fine sea salt
- 250 g unsalted butter cut into small chunks
- About 75ml cold water
For the filling
- 3 tablespoons light olive oil
- 400 g yellow onions (about
- 4 medium onions) thinly-sliced
- 4 cloves garlic crushed
- 1 bay leaf
- A sprig of fresh thyme
- 1 crisp eating apple
- 8 slices streaky bacon
- 200 g Comté sliced (18 or 24 months aged would give a deep, nutty taste)
Instructions
- To make the pastry: sift the flour and salt into a large bowl. Add the butter and rub in loosely (you need to see bits of butter).
- Make a well in the bowl and pour in the water, mixing until you have a firm rough dough (add extra water if needed).
- Cover with cling film and refrigerate for 20 mins.
- Put the pastry onto a lightly floured board, knead gently and form into a smooth rectangle. Roll the dough in one direction only, until 3 times the width, about 20 x 50cm. Keep edges straight and even. Don’t overwork the butter streaks – you should have a marbled effect. Fold the top third down to the centre, then the bottom third up and over that. Give the dough a quarter turn (to the left or right) and roll out again to three times the length.
- Fold as before, cover with cling film and chill for at least 20 mins before rolling to use.
- When the pastry is chilled, roll it into a square just over 1cm thick and cut it into 4 equal-sized pieces, then roll these out until 3mm thick – they should be about 18cm to 20cm diameter. Stack the pastry squares with squares of non-stick parchment in between, cover and refrigerate.
- Make the filling: warm the oil in a large frying pan, add the onions and a pinch of salt. Cook over a medium heat for a few minutes, until the onions start to colour. Lower the heat and stir in the garlic, bay leaf and thyme. Cook until the onions are generally golden and tender, but not mushy – about 15 minutes in total. If they dry out, lower the heat and cover the pan. Cool the onions completely, remove the thyme and strip the leaves into the onions. Discard the bay leaf.
- Cut the apple into 1mm slices. Cut the bacon into 1cm strips, place in a small frying pan over a low heat for 2 minutes until the fat starts to melt into the pan. Drain off the fat, remove from the heat and toss the apple slices with the bacon.
- Heat oven to 205 ̊C (185 ̊C fan).
- Remove the pastry squares from the fridge and lightly score a 2cm border around the edge.
- Place the squares (on their parchment) onto 2 baking sheets. Divide the onion mixture over the pastry, staying within the border.
- Press in the warm apples and bacon, ensuring they lay flat (or they will burn).
- Lay over the slices of Comté, fold up the pastry edges.
- Bake for about 20 to 25 minutes until the pastry is rich, golden brown.
- Serve immediately.
