4 ounces goat cheese or feta – Choose either for a tangy, creamy topping that contrasts perfectly with the sweet vegetables.
2 tablespoons olive oil – This helps roast the squash and caramelize the onions; feel free to use a flavored variety for extra kick!
1 teaspoon fresh thyme leaves – Fresh herbs elevate the flavors, offering a fragrant aroma and earthy undertone.
0.5 teaspoon salt – Essential for enhancing the flavors; feel free to adjust based on your preference.

How to Make Caramelized Onion Butternut Squash Tart

Follow these simple steps to prepare this delicious Caramelized Onion Butternut Squash Tart:

Step 1: Prepare the Ingredients
Preheat your oven to 400°F (200°C). Gather all your ingredients on the counter, making sure everything is at hand. Toss the cubed butternut squash with olive oil, salt, and pepper. Spread the squash out on a baking sheet, ensuring they don’t touch too much; we want those glorious caramelized edges.

Step 2: Roast the Squash
Roast the butternut squash for 25–30 minutes, or until they are golden and tender, flipping halfway through to ensure even cooking. The roasting will deepen the flavor and enhance the sweetness, bringing out the vegetable’s natural glory.

Step 3: Caramelize the Onions
While the squash is roasting, grab a large skillet and heat a tablespoon of olive oil over medium-low heat. Add the thinly sliced onions, stirring often. Be patient—they need to cook for about 30–40 minutes until they are golden brown, soft, and deeply caramelized. This step is crucial for building flavor!

Step 4: Prepare the Puff Pastry
On a lightly floured surface, roll out the sheet of thawed puff pastry and place it on a parchment-lined baking sheet. Score a 1-inch border around the edge and prick the center with a fork to prevent it from puffing up too much. Pre-bake the pastry for about 10 minutes until it’s just beginning to set.

Step 5: Assemble the Tart
Spread those beautiful caramelized onions over the pre-baked puff pastry. Next, top it with the glorious roasted butternut squash. Crumble the goat cheese or feta over the top, then sprinkle with fresh thyme leaves. Brush the edges with the beaten egg if you’re using it; this step adds a beautiful golden finish.

Step 6: Bake to Perfection
Pop it back in the oven and bake for another 15–20 minutes until the pastry is puffed and golden, and you just can’t resist the smell anymore. Once out of the oven, allow it to cool slightly before slicing. Serve warm or at room temperature as a delightful centerpiece or a savory snack.
