• 2 medium butternut squashes (about 2 lbs), peeled and diced
• 2 large onions, thinly sliced
• 2 tablespoons olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1 teaspoon fresh thyme (or 1/2 teaspoon dried thyme)

How to Make Caramelized Onion Butternut Squash Tart

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). This ensures that your tart bakes evenly and achieves that desired golden brown color.

Step 2: Prepare the Butternut Squash

• Toss diced squash with olive oil, salt, and pepper in a bowl.
• Spread the seasoned squash on a baking sheet in an even layer.
• Roast for 25-30 minutes until fork-tender and lightly browned.

Step 3: Caramelize the Onions

• In a skillet over medium heat, add olive oil.
• Once hot, add thinly sliced onions.
• Cook for about 20 minutes, stirring occasionally until they turn golden brown and soft.

Step 4: Roll Out the Puff Pastry

On a floured surface, roll out the puff pastry into a circle large enough to fit your tart pan. Prick the bottom with a fork to prevent bubbling during baking.

Step 5: Assemble the Tart

• Spread the caramelized onions over the pastry base evenly.
• Layer the roasted butternut squash on top of the onions.
• Crumble goat cheese over the squash filling.
• Drizzle with heavy cream and sprinkle fresh thyme throughout.

Step 6: Bake the Tart

Place your assembled tart in the preheated oven. Bake for 25-30 minutes until the pastry is golden brown and flaky.

Step 7: Cool and Serve

Once baked, allow the tart to cool for about 10 minutes before slicing. Serve warm or at room temperature. Enjoy!

Common Mistakes to Avoid

Cooking can be tricky, especially when making a Caramelized Onion Butternut Squash Tart. Here are some common mistakes and how to avoid them.

• Skipping the Preheating: Always preheat your oven before baking. This ensures even cooking and a perfectly golden crust.
• Not Cutting Vegetables Evenly: When dicing the butternut squash, make sure the pieces are uniform in size. This allows for consistent roasting and texture.
• Overcooking the Onions: Keep an eye on your onions while caramelizing them. If you cook them too long, they can burn instead of becoming sweet and golden.
• Using Cold Puff Pastry: Allow your puff pastry to come to room temperature before rolling it out. Cold pastry can be difficult to work with and won’t rise properly.
• Neglecting Flavor Balance: Taste your filling before assembling the tart. Adjust seasoning as needed to ensure a delicious final product.
