Ingredients:
Instructions:
- In a large bowl, combine the all-purpose flour and a pinch of salt. Add the cold butter pieces.
- Using a pastry cutter or your fingers, work the butter into the flour until the mixture resembles coarse crumbs.
- Add cold water, one tablespoon at a time, mixing until the dough starts to come together.
- Form the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
- While the dough chills, heat 1 tablespoon of olive oil in a large skillet over medium heat.
- Add the thinly sliced red onions and cook, stirring occasionally, until softened and caramelized (about 15-20 minutes).
- Stir in the vinegar and brown sugar, and cook for an additional 5 minutes until the mixture is thick and sticky.
- Season with salt and pepper to taste and set aside.
- Preheat the oven to 375°F (190°C).
- Slice the zucchini into thin rounds and halve the cherry tomatoes. Set aside.
- On a lightly floured surface, roll out the chilled dough into a circle about 12 inches in diameter and 1/8 inch thick.
- Transfer the dough to a tart pan, pressing it gently into the sides and trimming any excess dough.
- Spread the caramelized red onion relish evenly over the bottom of the tart crust.
- Arrange the zucchini slices in an overlapping pattern on top of the relish.
- Scatter the feta cheese crumbles over the zucchini.
- Finally, evenly distribute the halved cherry tomatoes on top.
- Place the tart in the preheated oven and bake for 35-40 minutes, or until the crust is golden brown and the vegetables are tender.
- Remove from the oven and let cool slightly before slicing.
- Serve the tart warm or at room temperature. Enjoy your delicious Red Onion Relish & Vegetable Tart!
Tips:
- Pre-bake the tart crust: Blind bake the tart crust for about 10-15 minutes at 350°F (175°C) before adding the filling to ensure a crisp and well-cooked bottom.
- Caramelize the onions properly: Cook the red onions over medium-low heat, stirring occasionally, until they become soft and caramelized. This can take up to 20 minutes but adds a deep, sweet flavor to the relish.
- Choose firm and fresh vegetables: Use fresh and firm zucchini and cherry tomatoes to maintain a good texture and vibrant color in the tart.
- Season the vegetables: Don't forget to season the zucchini and onions with salt and pepper to enhance their natural flavors.
- Use cold butter for the crust: Ensure the butter is cold when making the tart crust to achieve a flaky texture. You can even chill the mixture in the refrigerator if it starts getting too warm.
This red onion relish & vegetable tart is not only a feast for the eyes but also a treat for the taste buds. The combination of sweet, tangy, and savory flavors, along with a crispy crust, makes it a delightful dish for any occasion. Serve it warm or at room temperature, and enjoy the compliments from family and friends!
