Step‑by‑Step Instructions for Caramelized Onion Butternut Squash Tart
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This will ensure it's hot enough to roast the butternut squash perfectly. While the oven warms up, gather your ingredients and prep your baking sheet for the squash.
Step 2: Roast the Squash
In a large bowl, toss the diced butternut squashes with 1 tablespoon of olive oil, salt, and black pepper. Spread the seasoned squash on a baking sheet in a single layer and roast for 25-30 minutes, or until tender and slightly caramelized, stirring halfway for even cooking.
Step 3: Caramelize the Onions
While the squash roasts, heat the remaining 1 tablespoon of olive oil in a skillet over medium heat. Add the thinly sliced onions and a pinch of salt, cooking slowly for about 20 minutes. Stir occasionally until the onions turn golden brown and sweetly fragrant, achieving a deep caramel color.
Step 4: Prepare the Puff Pastry
On a lightly floured surface, roll out the puff pastry to fit your tart pan, ensuring it's about ¼ inch thick. Carefully place the pastry into the prepared tart pan, pressing it into the corners, and prick the bottom with a fork to allow for even baking and to prevent puffing.
Step 5: Assemble the Tart
Spread the beautifully caramelized onions evenly over the puff pastry base. Next, layer the roasted butternut squash on top, crumbling the goat cheese over it for a creamy touch. Drizzle heavy cream across the filling and sprinkle fresh thyme for a delightful herbaceous aroma.
Step 6: Bake the Tart
Place the assembled Caramelized Onion Butternut Squash Tart in the preheated oven and bake for 25-30 minutes. Keep an eye on it; the pastry should be golden brown and puffed up nicely, signaling that it’s time to be taken out and enjoyed.
Step 7: Cool and Serve
Once baked, remove the tart from the oven and let it cool for about 10 minutes before slicing. This cooling time allows the flavors to meld beautifully, making each slice an unforgettable treat, ready to be plated for you and your guests.

Expert Tips for Caramelized Onion Butternut Squash Tart
Choose Quality Pastry: Opt for high-quality puff pastry for a flaky, golden crust that enhances the tart's texture and taste.
Caramelize Slowly: Take your time when caramelizing the onions; low and slow cooking helps develop their sweetness without burning.
Season Generously: Don't skip seasoning the squash with salt and pepper. Proper seasoning elevates the flavor in this Caramelized Onion Butternut Squash Tart.
Avoid Soggy Pastry: Pricking the bottom of the puff pastry helps prevent it from becoming soggy. Better yet, bake it blind for a crispier base.

Cool Before Serving: Allow the tart to cool for 10 minutes before slicing; this helps it set nicely, making cleaner, more appealing slices.

Caramelized Onion Butternut Squash Tart Recipe FAQs
How do I know when my butternut squash is ripe for cooking?
Absolutely! When selecting butternut squash, look for ones that are firm and heavy for their size, with a smooth, deep tan skin. The stem should be dry and resemble a cork. Avoid any that have dark spots or blemishes, which can indicate spoilage. Ripe squash will have a sweet fragrance when you cut into it!
What’s the best way to store leftover Caramelized Onion Butternut Squash Tart?
I recommend placing any leftovers in an airtight container and storing them in the fridge for up to 3 days. This keeps the tart fresh while allowing those wonderful flavors to continue melding together, making it even tastier the next day!
Can I freeze the Caramelized Onion Butternut Squash Tart?
Absolutely! To freeze, start by allowing the tart to cool completely. Then, wrap it tightly in plastic wrap followed by a layer of aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 2 months. When you’re ready to enjoy, simply thaw it in the refrigerator overnight and reheat in a preheated oven at 350°F (175°C) for 15-20 minutes.
My onions burned while caramelizing. What should I do?
Very! If your onions burn, don't worry—just lower the heat next time! Caramelizing onions takes patience. Start at medium heat and give them a gentle stir every few minutes. If they start to browning too quickly, add a splash of water to the pan, and they'll soften without burning. Remember, it typically takes about 20 minutes for them to reach that beautiful caramel hue without getting burnt.
Are there any dietary considerations for this tart?
If you have food allergies or dietary needs, you can modify this recipe quite easily! For gluten-free options, look for gluten-free puff pastry available at specialty stores. If you're dairy-free, simply replace the goat cheese and heavy cream with non-dairy alternatives like cashew cream or nutritional yeast for added flavor. And don't forget, always check labels for allergens if you’re preparing this for guests with specific dietary restrictions!
