Ingredients for Caramelized Onion Butternut Squash Tart

2 cups cubed butternut squash – Choose ripe squash that’s firm and smooth for the best flavor and texture.
2 large yellow onions, thinly sliced – Sweet, yellow onions caramelize beautifully, adding depth to the tart.
1 sheet puff pastry, thawed – Use store-bought pastry for ease, but feel free to try homemade for an extra touch.
4 ounces goat cheese or feta, crumbled – Both cheeses add creamy, tangy notes that complement the squash perfectly.
2 tablespoons olive oil – Opt for extra virgin olive oil for better flavor and health benefits.
1 teaspoon fresh thyme leaves – Fresh thyme enhances the aroma and lends an earthy taste that brightens the dish.
0.5 teaspoon salt – Season to taste, enhancing the overall flavor.

How to Make Caramelized Onion Butternut Squash Tart
Follow these simple steps to prepare this delicious Caramelized Onion Butternut Squash Tart:
Step 1: Preheat and Prepare
Preheat your oven to 400°F (200°C). While it’s warming up, toss the cubed butternut squash in olive oil, salt, and pepper until all the pieces are nicely coated. Spread the squash on a baking sheet in a single layer for roasting.
Step 2: Roast the Squash
Roast the butternut squash for about 25–30 minutes until it’s golden and tender. The roasting process caramelizes the natural sugars, enhancing its sweetness. You might find it hard to resist eating it straight off the baking sheet!
Step 3: Caramelize the Onions
While the squash is roasting, let’s focus on those onions. In a large pan, heat 2 tablespoons of olive oil over medium-low heat, then add the sliced onions. Cook gently, stirring often, for 30–40 minutes until they turn a glorious golden brown and are incredibly soft. This step requires patience, but oh, the reward is worth it!
Step 4: Prepare the Puff Pastry
While your onions are caramelizing, roll out the thawed puff pastry on a parchment-lined baking sheet. Score a 1-inch border around the edge, and use a fork to prick the center to prevent it from puffing up too much during baking. This creates a beautiful well for your filling.
Step 5: Assemble the Tart
Once the onions are ready, spread them evenly over the pre-baked puff pastry. Top them with the roasted butternut squash and crumbled goat cheese or feta, then sprinkle the fresh thyme over everything. The aromatic combination will have your mouth watering!
Step 6: Bake to Perfection
If you’re feeling fancy, brush the edges of the pastry with the beaten egg to give it a shiny, golden glow. Bake your tart in the oven for 15–20 minutes until the pastry is puffed and golden. Remove it from the oven, and let it cool for a few minutes before slicing. It’s time to serve this masterpiece warm or at room temperature, and enjoy every delicious bite!
Enjoy the tactile joy of pulling apart the flaky crust and the explosion of flavors in every mouthful. Whether you’re hosting a brunch, unwinding with loved ones, or just treating yourself after a long week, this Caramelized Onion Butternut Squash Tart is sure to make you feel like a culinary rock star!
