Step-by-step Preparation of Caramelized Onion Tart
Creating a Caramelized Onion Tart with Gorgonzola and Brie is a delightful culinary adventure that brings fragrant onions, creamy cheeses, and flaky pastry together in a harmonious blend. Let’s walk through each step to ensure your tart turns out absolutely scrumptious.
Caramelize the onions to perfection
The heart of this tart lies in the caramelized onions, which contribute a deep, rich flavor. Start by heating 2 tablespoons of extra virgin olive oil in a large, deep pan over medium-high heat. Add 4 cups of sliced onions and sauté them for about 10 minutes until they're wilted and beginning to brown. This is where the magic happens!
Next, sprinkle in 1 tablespoon of brown sugar and drizzle 2 tablespoons of balsamic vinegar, along with ½ teaspoon of salt and ½ teaspoon of pepper. These ingredients will enhance the sweetness of the onions as they soften. Reduce the heat to low and let the onions cook uncovered for 20 to 25 minutes, stirring occasionally. The goal is to achieve a lovely, caramelized hue and robust flavor. If at any point the onions look dry, simply add a splash of water to keep them moist.
Preparing the puff pastry
While the onions are caramelizing, it’s time to prepare the puff pastry. Make sure you defrost an 8-ounce sheet of frozen puff pastry for a couple of hours in your fridge before using it. Preheat your oven to 400°F.
Once the pastry is ready, roll it out into a 10 to 14-inch rectangle (or any shape you prefer). Place it on a baking sheet lined with parchment paper to prevent sticking. Remember to prick the pastry with a fork every couple of inches to keep it from puffing up too much while baking.
Layering the onions and cheese
Now comes the fun part—layering! Spread the beautifully caramelized onions over the pastry, ensuring they reach all the edges. Next, dot the tart with 2 ounces of diced brie cheese and 2 ounces of Gorgonzola—the creamy richness will complement the sweetness of the onions perfectly. For an aromatic touch, sprinkle 2 tablespoons of chopped fresh tarragon on top. If you're not baking right away, it’s a good idea to refrigerate your tart until you’re ready.
Baking the tart until golden
Pop the tart in the preheated oven and bake for about 18 to 20 minutes. Keep an eye out for that golden-brown color and melted cheese, which means it’s ready to come out. The delightful aroma of the baking tart will surely have your mouth watering.
Letting it cool and slicing it up
After baking, let your Caramelized Onion Tart with Gorgonzola and Brie cool for about 5 minutes. This brief rest period helps the pastry set a little, making it easier to slice. Cut it into wedges or squares, and you’re all set to serve this stunning creation to friends or family. Enjoy the wonderful blend of flavors and make sure to relish every bite!

Variations of the Caramelized Onion Tart
Adding seasonal vegetables for a twist
Elevate your Caramelized Onion Tart with Gorgonzola and Brie by introducing seasonal vegetables. Think of roasted butternut squash in the fall or fresh asparagus in the spring. You can even experiment with sautéed mushrooms or sautéed spinach for added depth of flavor. These veggies not only complement the onions and cheeses perfectly but also boost the nutritional value of your tart. Make it your own, and you'll surprise your guests with delightful new flavors!
Alternative cheese choices for different flavors
While Gorgonzola and Brie create a luxurious taste, don't hesitate to swap for other cheeses! Try aged cheddar for a sharper bite or goat cheese for a creamy texture and tanginess. Each option transforms the flavor profile while still allowing the sweet notes of caramelized onions to shine. For a unique twist, consider blue cheeses with varied intensities or even a touch of ricotta for a lighter variation. The possibilities are endless, so feel free to experiment!
Cooking Tips and Notes for Caramelized Onion Tart
How to Ensure the Pastry Stays Crisp
To achieve that delightful crunch in your Caramelized Onion Tart with Gorgonzola and Brie, make sure to prick the puff pastry with a fork before baking. This prevents big bubbles from forming.

Tricks for Flavorful Caramelized Onions
