Ingredients
- 1 sheet of ready-made puff pastry
- 2 large red onions, thinly sliced
- 2 tablespoons of olive oil
- 1 tablespoon of balsamic vinegar
- 100g blue cheese, crumbled
- 1 tablespoon of fresh thyme leaves
- Salt and pepper, to taste
- 1 egg, beaten (for glazing)
Instructions
Step 1: Prepare the Puff Pastry
Start by preheating your air fryer to 180°C. Roll out the puff pastry onto a lightly floured surface. Transfer the pastry onto a piece of parchment paper that will fit your air fryer basket. Create a small border around the pastry by gently folding and pinching the edges.
Step 2: Caramelize the Red Onions
Heat olive oil in a frying pan over medium heat. Add the sliced red onions and stir occasionally, cooking until they become soft and translucent. Add the balsamic vinegar and continue to cook until the onions are caramelized and golden brown. Season with salt and pepper to taste.
Step 3: Assemble the Tart
Spread the caramelized onions evenly over the prepared puff pastry, staying within the border. Crumble the blue cheese over the onions and sprinkle with fresh thyme leaves. Brush the pastry edges with the beaten egg for a nice golden finish.
Step 4: Air Fry the Tart
Carefully transfer the tart, along with the parchment paper, into the air fryer basket. Cook for 15-20 minutes or until the pastry is puffed up and golden brown and the cheese is melted and bubbly. Enjoy your delicious tart hot, warm, or even at room temperature.
Serving Suggestions
This tart is incredibly versatile and pairs beautifully with a simple side salad or a lightly dressed arugula. It's perfect for serving as a starter, a main course, or even an elegant party appetizer.
Tips for Home Cooks
- Ensure the puff pastry remains cold until ready to use for the best flaky texture.
- Feel free to experiment with additional toppings like walnuts or prosciutto for extra flavour.
- Different air fryers may vary, so keep an eye on your tart during cooking to achieve the perfect finish.
Additional Considerations
If you're looking to customize this recipe, consider trying different types of cheese such as goat cheese or feta for a new taste dimension. Also, caramelized onions can be made in advance to save time when you're ready to assemble your tart.
