Step‑by‑Step Instructions for Caramelized Onion Butternut Tart
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While the oven heats up, line a baking sheet with parchment paper to prevent sticking. This preparation will ensure a crisp bottom for your Caramelized Onion Butternut Tart as it bakes. Keep the parchment ready on your working surface for easy assembly later.
Step 2: Caramelize the Onions
In a large skillet, heat 1 tablespoon of extra virgin olive oil over medium heat. Add the sliced yellow onions, stirring occasionally for about 15-20 minutes until they turn a rich golden brown and become delightfully sweet. Lower the heat if necessary to avoid burning, as you want the onions to caramelize slowly for the best flavor in your tart.
Step 3: Cook the Butternut Squash
In a separate skillet, add the remaining tablespoon of olive oil and heat it over medium-high. Add the cubed butternut squash, sautéing for 10-15 minutes. Stir occasionally until the squash is tender but still firm, with a slight caramelization starting to form. This step will enhance the natural sweetness, which beautifully complements the onions.
Step 4: Combine the Filling
In a mixing bowl, gently combine the caramelized onions, sautéed butternut squash, fresh thyme, salt, and pepper. Stir carefully to mix without mashing the squash, ensuring the flavors meld together evenly. The combination will create a delicious filling for the Caramelized Onion Butternut Tart that is both savory and rich.
Step 5: Assemble the Tart
Roll out the chilled puff pastry on the prepared baking sheet, ensuring it’s an even thickness. Spread the squash and onion filling evenly over the pastry, leaving a small border around the edges. Sprinkle crumbled goat cheese generously on top of the filling, making sure every bite will have that creamy goodness as the tart bakes.
Step 6: Bake the Tart
Place your assembled Caramelized Onion Butternut Tart in the preheated oven. Bake for 25-30 minutes, or until the puff pastry is golden brown and flaky. Keep an eye on it towards the end of the baking time—once it’s beautifully risen and the filling is set, it’s ready to impress at your table.
Make Ahead Options
Preparing the Caramelized Onion Butternut Tart ahead of time is a fantastic way to save precious minutes during a busy weeknight! You can caramelize the onions and cook the butternut squash up to 24 hours in advance; simply let them cool and store them separately in airtight containers in the refrigerator. When you’re ready to serve, combine these components with the thyme and seasonings before assembling the tart onto the puff pastry. The assembled tart can also be refrigerated for up to 3 days before baking—just make sure to tightly cover it to maintain freshness. When it’s time to enjoy, bake directly from the fridge; just add an extra few minutes of cooking to ensure it’s perfectly heated through. With these make-ahead options, you’ll have a delicious meal ready to impress with minimal effort!

Expert Tips for Caramelized Onion Butternut Tart
- Patience with Onions: Allow onions enough time to caramelize properly; rushing this step can lead to a bitter taste. Medium-low heat is key.

- Garnish for Flair: Consider adding fresh herbs or a sprinkle of nuts on top after baking for an elegant finish and an extra layer of texture.

Caramelized Onion Butternut Tart Recipe FAQs
How do I choose ripe butternut squash?
Look for butternut squash that feels heavy for its size and has a matte, tan skin. Avoid those with soft spots or deep cuts. The deeper the color of the skin, the sweeter and more flavorful it generally is!
How should I store leftover Caramelized Onion Butternut Tart?
Store your leftover tart in an airtight container in the refrigerator for up to 3 days. To ensure it retains its delicious crispness, I recommend reheating it at 350°F (175°C) for 10-15 minutes until warmed through and the pastry regains its flaky texture.
Can I freeze Caramelized Onion Butternut Tart?
Absolutely! You can freeze the unbaked tart for up to a month. Simply assemble it as instructed, but do not bake. Wrap it tightly in plastic wrap, then place it in a freezer bag. When ready to enjoy, bake it directly from the freezer, adding an extra 5-10 minutes to the cooking time.
What should I do if my onions burn while caramelizing?
If you find your onions are burning, it’s likely that your heat is too high. Lower the temperature to medium-low and add a splash of water or broth to the pan. This can help lift the burn bits from the pan while allowing the onions to continue cooking gently and avoid bitterness.
Are there any dietary considerations for this recipe?
This Caramelized Onion Butternut Tart is vegetarian, and it can be made gluten-free by using gluten-free puff pastry. If you or your guests have dairy restrictions, consider substituting the goat cheese with a plant-based cheese alternative for a similar creamy texture without the dairy.
Can pets eat butternut squash?
Yes, butternut squash is safe for most pets in moderation. It’s nutritious and can be a healthy treat! However, avoid adding seasonings or onions, as those can be harmful to animals. Always consult your veterinarian if you’re unsure about introducing new foods to your pet’s diet.
