Let’s Make it Together
Prepare Your Ingredients: Begin by preheating your oven to 400°F (200°C). Chop the butternut squash into small cubes and slice onions thinly, setting them aside.
Sauté the Onions: In a large skillet over medium heat, add olive oil. Once hot, toss in sliced onions and some salt, stirring until they turn golden-brown and sweet-smelling.
Add Butternut Squash: Stir in diced butternut squash along with thyme leaves. Sauté until squash softens slightly—about 10 minutes should do.
Create Your Tart Base: Roll out the puff pastry on a floured surface until about 1/8 inch thick. Carefully transfer it to a tart pan, pressing gently into the corners.
Assemble Your Tart Filling: Spread sautéed onion and squash mixture evenly over the pastry base. Crumble goat cheese on top before drizzling with balsamic vinegar for extra zing.
Bake to Perfection!: Slide your tart into the oven and bake for 25-30 minutes until golden brown and puffy—a true feast for both eyes and stomach!
