Assemble the Tart: Roll out your puff pastry into your prepared tart pan, pressing it gently into place. Layer in those scrumptious caramelized onions followed by the roasted squash cubes scattered artfully.
Add Cheese and Bake: Crumble goat cheese (or feta) over the top of your tart as if you’re sprinkling fairy dust. Bake in the preheated oven for about 25-30 minutes until golden brown and puffed.
Savor & Serve!: Once baked, let it cool slightly before slicing into pieces that are just waiting to be devoured. Pair with a nice salad or enjoy solo—it’s delightful either way!
