this Recipe

Ingredients:

• For the Crust:
• 1 1/4 cups (150g) all-purpose flour, plus more for dusting
• 1/2 teaspoon salt
• 1/2 cup (113g) cold unsalted butter, cut into small cubes
• 1/4 cup (60ml) ice water
• For the Onion Filling:
• 3 tablespoons olive oil
• 3 pounds (approximately 6 large) yellow onions, thinly sliced
• 1 teaspoon salt, plus more to taste
• 1/2 teaspoon freshly ground black pepper, plus more to taste
• 1/4 cup dry white wine (such as Sauvignon Blanc or Pinot Grigio)
• 1 tablespoon balsamic vinegar
• 1 teaspoon dried thyme
• 1/4 cup heavy cream
• 2 large eggs
• 1/4 cup grated Gruyère cheese (optional, but highly recommended!)

Preparing the Crust:

1. Combine Dry Ingredients: In a large bowl, whisk together the flour and salt. This ensures the salt is evenly distributed throughout the dough.
2. Cut in the Butter: Add the cold, cubed butter to the flour mixture. Using a pastry blender or your fingertips, cut the butter into the flour until the mixture resembles coarse crumbs. The key here is to work quickly so the butter stays cold. Cold butter is crucial for a flaky crust! You should see some pea-sized pieces of butter remaining.
3. Add Ice Water: Gradually add the ice water, one tablespoon at a time, mixing gently after each addition. Continue adding water until the dough just comes together. Be careful not to overmix! Overmixing develops the gluten in the flour, resulting in a tough crust.
4. Form the Dough: Turn the dough out onto a lightly floured surface. Gently form it into a disc. If the dough is too sticky, add a little more flour, but be sparing.
5. Chill the Dough: Wrap the dough disc tightly in plastic wrap and refrigerate for at least 30 minutes, or up to 2 hours. This allows the gluten to relax, making the dough easier to roll out. Chilling also helps the butter solidify, which contributes to flakiness.

Preparing the Onion Filling:

1. Caramelize the Onions: Heat the olive oil in a large, heavy-bottomed skillet over medium-low heat. Add the sliced onions, salt, and pepper. The key to perfectly caramelized onions is patience! Don’t rush the process.
2. Cook Slowly: Cook the onions, stirring occasionally, for about 45-60 minutes, or until they are deeply golden brown and very soft. The onions will initially release a lot of liquid, which will then evaporate as they cook. As they cook, they will become sweeter and more flavorful. Reduce the heat if the onions start to burn.
3. Deglaze the Pan: Once the onions are caramelized, add the white wine and balsamic vinegar to the skillet. Scrape up any browned bits from the bottom of the pan. This adds depth of flavor to the filling.
4. Add Thyme: Stir in the dried thyme. Cook for another minute or two, until the wine and vinegar have mostly evaporated.
5. Cool Slightly: Remove the skillet from the heat and let the onion mixture cool slightly.

Assembling and Baking the Tarte:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Roll Out the Dough: On a lightly floured surface, roll out the chilled dough into a circle about 12 inches in diameter.
3. Transfer to Tart Pan: Carefully transfer the dough to a 9-inch tart pan with a removable bottom. Gently press the dough into the bottom and up the sides of the pan.
4. Trim the Edges: Trim any excess dough from the edges of the pan. You can use a rolling pin to roll over the top of the pan, or simply trim with a knife.
5. Blind Bake (Optional): For a crispier crust, you can blind bake the crust before adding the filling. To do this, prick the bottom of the crust with a fork. Line the crust with parchment paper and fill with pie weights or dried beans. Bake for 15 minutes. Remove the parchment paper and weights and bake for another 5-10 minutes, or until the crust is lightly golden brown.
6. Prepare the Custard: In a medium bowl, whisk together the heavy cream and eggs. Season with salt and pepper to taste.
7. Assemble the Tarte: Spread the caramelized onion mixture evenly over the bottom of the tart crust.
8. Pour in the Custard: Pour the cream and egg mixture over the onions.
9. Add Cheese (Optional): Sprinkle the grated Gruyère cheese over the top of the tart.
10. Bake: Bake for 30-40 minutes, or until the crust is golden brown and the filling is set. The filling should be slightly jiggly in the center, but not liquid.
11. Cool Slightly: Let the tarte cool in the pan for at least 15 minutes before removing it from the pan. This allows the filling to set up a bit more.
12. Serve: Carefully remove the tarte from the pan and slice into wedges. Serve warm or at room temperature. This tarte is delicious on its own, or served with a side salad.

Tips for Success:

• Use Cold Ingredients: Cold butter and ice water are essential for a flaky crust.
• Don’t Overmix the Dough: Overmixing develops the gluten in the flour, resulting in a tough crust.
• Caramelize the Onions Slowly: Patience is key to perfectly caramelized onions. Don’t rush the process.
• Adjust Seasoning to Taste: Taste the onion filling and adjust the seasoning as needed.
• Blind Bake for a Crisper Crust: If you prefer a crispier crust, blind bake it before adding the filling.

Variations:

• Add Bacon or Pancetta: For a richer flavor, add cooked bacon or pancetta to the onion filling.
• Use Different Cheeses: Experiment with different cheeses, such as Parmesan, Fontina, or goat cheese.
• Add Herbs: Try adding other herbs, such as rosemary or sage, to the onion filling.
• Make it Vegetarian/Vegan: Omit the cheese and use a plant-based cream alternative to make it vegan.

Storage Instructions:

• Refrigerate: Store leftover tarte in the refrigerator for up to 3 days.
• Reheat: Reheat the tarte in the oven at 350°F (175°C) until warmed through. You can also reheat individual slices in the microwave.

Feeling adventurous? There are so many variations you can explore! Try adding a sprinkle of crumbled goat cheese or Gruyère before baking for an extra layer of creamy, tangy flavor. A few sprigs of fresh thyme or rosemary added during the caramelization process will infuse the onions with an herbaceous aroma. For a spicier kick, a pinch of red pepper flakes will do the trick.
