Instructions
- Warm the oven up to 200°C (400°F). Put parchment paper on a baking sheet to make it easy to clean up.
- Start by making the onions sweet. Warm the olive oil and butter in a big pan over medium-low heat until the butter melts.
- Toss the thinly sliced onions into the pan and cook, stirring every now and then, for about 20 to 25 minutes, or until they are soft and golden brown.
- Add the dried thyme, salt, pepper, and sugar to the caramelised onions, and stir them all together. Take the pan off the heat and set it aside.
- Get the puff pastry ready while the onions are being caramelised. When the puff pastry sheet is no longer frozen, roll it out into a rectangle shape on a lightly floured surface. The rectangle should be about 9×12 inches.
- Place the puff pastry that has been rolled out on the baking sheet that has been prepared.
- Cut a line about an inch from the edge of the puff pastry with a sharp knife, being careful not to cut all the way through. This edge will rise up and make a crust for the tart.
- To keep the puff pastry from rising too much while it’s baking, poke holes in the middle of it all over with a fork.
- Within the edge of the puff pastry, spread the caramelised onions out evenly in the middle.
- Cover the caramelised onions evenly with the shredded Gruyere cheese (or any other cheese of your choice).
- Beat the egg and brush it around the edges of the puff pastry. This will make a golden, shiny crust when it’s baked.
- Warm the oven up and put the tart in it. Bake it for 20 to 25 minutes, or until the puff pastry is golden brown and puffed up around the edges.
- Pick up the caramelised onion tart from the oven and let it cool a bit on the baking sheet.
- If you want to add some colour and flavour, you can sprinkle fresh thyme leaves on top of the tart.
- Take the tart and cut it into squares or rectangles. Serve it warm as a starter, side dish, or light meal.
Tips and Variations
- Try different kinds of cheese, like Swiss, fontina, or cheddar, to find the one you like best.
- For more taste and texture, cook some bacon, gammon or mushrooms and add them to the tart.
- For a sweet and sour finish, drizzle a balsamic glaze over the tart when it’s done.
- You can make little tartlets by cutting the puff pastry into squares and putting cheese and caramelised onions on top of each one.
- For a full meal, serve the caramelised onion tart with a crisp green salad dressed with a light vinaigrette.
