- 1 pre-made puff pastry sheet - 2 large yellow onions, thinly sliced - 2 tablespoons olive oil - 1 tablespoon balsamic vinegar - 1 teaspoon fresh thyme leaves - Salt and freshly ground black pepper to taste - 4 ounces goat cheese, crumbled - 1 tablespoon honey - 1 egg, beaten (for egg wash) This tart is a great choice for many diets. It contains dairy from the goat cheese. If you're lactose intolerant, you can try lactose-free cheese. The tart is vegetarian but not vegan due to the cheese and egg wash. You can switch the puff pastry for a gluten-free crust if needed. Instead of yellow onions, use sweet onions for a milder taste. Feta cheese can replace goat cheese for a different flavor. If you prefer a different herb, try rosemary or oregano instead of thyme. {{ingredient_image_2}} 1. Preheat your oven to 400°F (200°C). 2. Line a baking sheet with parchment paper. This step helps prevent sticking. 3. Slice two large yellow onions thinly. 4. Heat two tablespoons of olive oil in a large skillet over medium heat. 5. Add the sliced onions to the skillet and stir often. Cook until they soften, about 10 minutes. 6. Lower the heat to low and keep cooking the onions for 15-20 minutes. Stir occasionally until they turn golden brown. 7. Add one tablespoon of balsamic vinegar and one teaspoon of fresh thyme leaves to the onions. Season with salt and pepper. Mix well. 8. Remove the skillet from heat and let the mixture cool slightly. 1. Roll out the pre-made puff pastry sheet on a lightly floured surface. Shape it to fit your baking sheet. 2. Use a sharp knife to score a 1-inch border around the pastry. Be careful not to cut all the way through. 3. Spoon the caramelized onion mixture into the center of the pastry, staying within the border. 4. Crumble four ounces of goat cheese over the onion mixture. Drizzle one tablespoon of honey on top for sweetness. 5. Brush the edges of the pastry with a beaten egg to give it a nice color. 1. Bake the tart in the preheated oven for 25-30 minutes. Watch for a golden-brown color and a puffed-up pastry. 2. After baking, take the tart out and let it cool for a few minutes. 3. Slice the tart into portions, and serve warm. For a nice touch, garnish with fresh thyme leaves. 4. Pair the tart with a simple arugula salad drizzled with olive oil and lemon juice for a refreshing side. To get great caramelized onions, start with yellow onions. Slice them thinly for even cooking. Heat olive oil in your skillet over medium heat. Add the onions and stir often. After about 10 minutes, they should be soft. Lower the heat and keep cooking for 15-20 minutes. This will help them turn a rich brown. Don’t rush; patience is key here! If you want more flavor, add balsamic vinegar and thyme. This enhances the sweet taste of the onions. When using puff pastry, make sure it is cold. Cold pastry puffs better in the oven. Roll it out gently on a floured surface. Keep it about 1/8 inch thick. Don’t overwork the dough. Score a border around the edge, but don’t cut all the way through. This helps the crust rise and stay flaky. Brush the edges with beaten egg to get a golden color. This small step makes a big difference. To boost the flavor of your tart, think about adding honey. A drizzle on top of the goat cheese balances the tartness. You can also swap goat cheese for feta or ricotta for a twist. Fresh herbs like rosemary or basil can add a new taste. Consider adding veggies like spinach or mushrooms for extra nutrition. Each change brings a new layer of flavor to your dish. Each bite should be a delightful surprise! Pro Tips Use Fresh Thyme: Fresh thyme adds a wonderful aroma and flavor to the tart. If you can, use fresh rather than dried for the best taste. Caramelize Slowly: Take your time caramelizing the onions on low heat. This develops their natural sweetness and depth of flavor. Don’t Skip the Egg Wash: The egg wash gives the pastry a beautiful golden color and shine. Brush it generously along the edges before baking. Experiment with Cheeses: While goat cheese is delicious, feel free to mix in or substitute with other cheeses like feta or ricotta for varied flavors. {{image_4}} You can switch up the cheese for different tastes. Try feta for a tangy kick. Cream cheese can add a rich, smooth texture. For a sharper flavor, use aged cheddar. These cheeses melt well and work great in the tart. Add more veggies to your tart for extra flavor and nutrition. Sautéed spinach adds a nice green touch. Thin slices of zucchini can also work well. Roasted red peppers bring a sweet and smoky taste. Feel free to mix and match your favorite veggies. Herbs can change the whole flavor of your tart. Basil or parsley can add freshness. A sprinkle of chili flakes gives a bit of heat. You can also use oregano for an earthy flavor. Experiment and find your perfect blend! To keep your tart fresh, let it cool completely. Then, wrap it in plastic wrap or place it in an airtight container. Store it in the fridge for up to three days. If you leave it out, the crust will get soggy. To reheat, preheat your oven to 350°F (175°C). Place the tart on a baking sheet, and cover it lightly with foil. Heat for about 10-15 minutes. This will help the crust stay crisp and warm the filling evenly. Avoid using the microwave, as it can make the pastry soft. You can freeze the tart before or after baking. If freezing before, wrap it tightly in plastic wrap and then foil. It can last in the freezer for up to two months. If you bake it first, let it cool, then wrap and freeze. To use, thaw it in the fridge overnight, then reheat as shown above. Yes, you can make this tart ahead of time. You can cook the onions and prepare the pastry in advance. Store the caramelized onions in the fridge. Roll out the pastry but do not bake it. When ready to eat, just assemble the tart and bake it fresh. This way, you enjoy warm, flaky goodness. To make a gluten-free version, switch to gluten-free puff pastry. Many brands offer this option. Check the ingredients to ensure they fit your needs. You can also try making a crust from ground almonds or oats. Just press it into your tart pan. Bake it briefly before adding the filling. This tart pairs well with a simple salad. I suggest a fresh arugula salad. Drizzle it with olive oil and lemon juice. The tart’s rich flavors balance nicely with the salad’s brightness. You can also serve it with a glass of light white wine.

Ingredients
  

  • 1 sheet pre-made puff pastry
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons olive oil
  • 1 tablespoon balsamic vinegar
  • 1 teaspoon fresh thyme leaves
  • to taste salt and freshly ground black pepper
  • 4 ounces goat cheese, crumbled
  • 1 tablespoon honey
  • 1 egg beaten (for egg wash)

Instructions
 

  • Begin by preheating your oven to 400°F (200°C). Prepare a baking sheet by lining it with parchment paper to prevent sticking.
  • In a large skillet, heat the olive oil over medium heat. Add the thinly sliced onions and cook, stirring frequently, until they become soft and translucent, which should take about 10 minutes.
  • Once the onions are softened, reduce the heat to low. Continue to cook the onions for an additional 15-20 minutes, stirring occasionally, until they turn a deep golden brown and develop a caramelized flavor.
  • Incorporate the balsamic vinegar, fresh thyme leaves, and season generously with salt and pepper. Mix well, then remove the skillet from heat and allow the mixture to cool slightly.
  • On a lightly floured surface, roll out the puff pastry to form a rectangle (or keep it circular if you prefer a round tart) that will fit your baking sheet. Transfer the rolled pastry to the prepared baking sheet.
  • Using a sharp knife, lightly score a 1-inch border around the edges of the pastry. Be careful not to cut all the way through; this will create a beautiful crust when baked.
  • Evenly distribute the caramelized onion mixture within the scored border of the pastry. Sprinkle crumbled goat cheese over the top, followed by a drizzle of honey to add a touch of sweetness.
  • To enhance the color and finish of your tart, brush the edges of the pastry with the beaten egg wash.
  • Bake in the preheated oven for 25-30 minutes, or until the pastry is fully puffed up and has acquired a beautiful golden-brown color.
  • Once baked, remove the tart from the oven and allow it to cool for a few minutes before slicing it into portions.
