Preparation time: 30 minutes
Baking time: 25 minutes
Total time: 55 minutes
Servings: 6 servings

Necessary ingredients:

For the dough:
- 600 g flour
- 2 tablespoons white wine
- 40 g butter at room temperature
- 1 tablespoon sage-flavored olive oil
- 1 tablespoon white truffle-flavored olive oil
- 1 teaspoon dried thyme
- 1/2 teaspoon lemon pepper (or white pepper)
- 1/2 teaspoon dried rosemary

For the filling:
- 1 large red onion
- 100 g grated cheese
- 2 tablespoons tomato juice/paste
- Salt to taste
- Fresh herbs (optional, for decoration)

Step-by-step preparation:

1. Preparing the dough: In a large bowl, sift the flour to eliminate any lumps. Add the diced butter, sage-flavored olive oil, truffle oil, white wine, thyme, pepper, and rosemary. Mix the ingredients with your fingers until you obtain a sandy mixture.

2. Forming the dough: Add cold water, one tablespoon at a time, until the dough becomes smooth and slightly elastic. Do not over-knead to maintain a fragile texture. Wrap the dough in plastic wrap and let it rest in the refrigerator for 20 minutes. This will help develop the flavors and firm up the texture.

3. Preparing the pan: Preheat the oven to 180°C. After the dough has rested, roll it out on a floured surface to fit a rectangular baking dish. Ensure the sheet is even, without thin areas.

4. Creating the edge: Using the leftover dough, form small strips that you will twist like a snail shell. Attach them to the edge of the tart, gently pressing with your fingers to secure them.

5. Preparing the filling: Slice the red onion into thin rings or cubes, depending on your preference. This will add an interesting texture to the tart. In a small bowl, mix the tomato paste with a little salt, then evenly spread this mixture over the base of the tart.

6. Assembling the tart: Sprinkle the grated cheese over the tomato paste and add the slices of red onion. This is when the sweet flavor of the onion will perfectly combine with the cheese.

7. Baking: Place the tart in the preheated oven and bake for 20-25 minutes, or until the edges turn golden and the filling starts to brown. The color of the tart will be appealing, and the aroma will fill the entire kitchen.

8. Serving: Let the tart cool slightly before slicing. You can serve it warm or at room temperature. A delicious combination is with a fresh green salad or a glass of white wine.

Useful tips:

- Sweet onion: Make sure to use quality red onions, as they are sweeter than regular onions. You can also add a little brown sugar to the filling to enhance the sweetness.
- Dough: If you want a quicker option, you can use store-bought tart dough, but the taste will be different.
- Variations: Experiment with different cheeses, such as goat cheese or feta, to give the tart a distinct note. You can also add olives or fresh herbs to the filling.
- Garnishes: An interesting idea would be to serve the tart with a garlic yogurt sauce or an olive emulsion.

Red onion is an excellent source of antioxidants, vitamins C and B6, as well as essential minerals such as potassium and manganese. Additionally, consuming onions can help reduce inflammation and improve heart health due to their natural compounds.
