Instructions

Step 1: Prepare the Crust

  1. Combine Dry Ingredients: In a large mixing bowl, combine 2 cups (250 g) of all-purpose flour and 1/2 teaspoon salt. Stir well to evenly distribute the salt.
  2. Add Oil: Pour in 1/2 cup (120 ml) of vegetable oil and mix until the flour resembles coarse crumbs. The oil will help create a flaky texture in the crust.
  3. Incorporate Water: Gradually add 1/4 cup (60 ml) of cold water, mixing until the dough comes together. If the dough feels too dry, add a little more water, one tablespoon at a time, until it holds together without being sticky.
  4. Chill the Dough: Form the dough into a ball, flatten it into a disk, and wrap it in plastic wrap. Refrigerate for at least 30 minutes. Chilling the dough will make it easier to roll out and help it maintain its shape while baking.

Step 2: Caramelize the Onions

  1. Slice the Onions: While the dough is chilling, peel and thinly slice 3 large onions. A sharp knife is crucial for achieving even slices, which will caramelize uniformly.
  2. Heat the Oil: In a large skillet over medium heat, add 3 tablespoons of olive oil. Allow the oil to heat for a minute.
  3. Add Onions: Add the sliced onions to the skillet, along with 1 teaspoon salt and 1 teaspoon sugar (if using). The salt will help draw out moisture, and the sugar will enhance the caramelization.
  4. Cook Slowly: Stir the onions occasionally to prevent burning. Cook for about 30-40 minutes until they become golden brown and caramelized. If the onions start to stick, reduce the heat and add a splash of water to deglaze the pan.
  5. Finish with Balsamic: Once caramelized, stir in 1 teaspoon balsamic vinegar, 1 teaspoon dried thyme, and 1/2 teaspoon black pepper. Cook for an additional minute to allow the flavors to meld. Remove from heat and let cool slightly.

Step 3: Prepare the Filling

  1. Mix the Cream Ingredients: In a mixing bowl, combine 1 cup (240 ml) of coconut cream (or cashew cream), 2 tablespoons nutritional yeast, and the dissolved 1 tablespoon cornstarch. Whisk until smooth and creamy. This mixture will add a delicious creaminess to the filling.
  2. Combine with Onions: Once the onions have cooled slightly, fold them into the cream mixture, ensuring an even distribution of onions throughout the filling.

Step 4: Assemble the Tart

  1. Preheat the 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. This will ensure that the dough is large enough to fit your 9-inch tart pan.
  3. Transfer to Tart Pan: Carefully transfer the rolled-out dough to the tart pan, gently pressing it into the edges and bottom. Trim any excess dough from the edges for a clean finish.
  4. Add the Filling: Pour the caramelized onion and cream mixture into the prepared crust, spreading it evenly with a rubber spatula.

Step 5: Bake the Tart

  1. Bake: Place the tart in the preheated oven and bake for 30-35 minutes, or until the filling is set and the crust is lightly golden. Keep an eye on it to ensure the crust doesn’t burn.
  2. Cool Slightly: Once baked, remove the tart from the oven and let it cool in the pan for about 10 minutes before carefully transferring it to a wire rack. This will help it firm up slightly, making it easier to slice.

Step 6: Serve and Garnish

  1. Slice the Tart: Once cooled, slice the tart into wedges or squares, depending on your preference.
  2. Garnish: If desired, garnish each slice with fresh herbs such as thyme or parsley for an added touch of freshness and color.
  3. Enjoy: Serve the Vegan Caramelized Onion Tart warm or at room temperature. It pairs wonderfully with a simple side salad or a light vinaigrette.

Storage and Serving Suggestions

  1. Storing Leftovers: Store any leftover tart in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
  2. Make Ahead: This tart can be prepared a day in advance. Just bake it and store it in the refrigerator, then reheat before serving.

Tips for Success

  • Caramelization: Patience is key when caramelizing onions. The longer you cook them, the more flavor and sweetness they will develop.
  • Dough Handling: If the dough becomes too warm while rolling, refrigerate it for a few minutes to make it easier to handle.
  • Flavor Variations: Feel free to experiment by adding sautéed mushrooms, spinach, or different herbs to the filling for a unique twist.
