Vegetables & Herbs
- 2 cups butternut squash, peeled and cubed
- 2 cups assorted mushrooms (cremini or baby bella), sliced
- 2 cloves garlic, minced
- 2 shallots, minced
- 1 tablespoon fresh thyme leaves
- 1 tablespoon fresh sage, chopped
Dairy & Cheese
- 1/2 cup grated Parmesan cheese
Pastry & Oils
- 1 sheet puff pastry, thawed
- 2 tablespoons olive oil (for roasting and sautéing)
Seasonings
- Salt, to taste
- Freshly ground black pepper, to taste
- Roast the Butternut Squash: Preheat the oven to 400°F (200°C). Toss the cubed butternut squash with 1 tablespoon olive oil, salt, and pepper. Spread evenly on a baking sheet and roast for 20-25 minutes until tender and slightly caramelized.
- Sauté the Mushrooms and Aromatics: While the squash roasts, heat 1 tablespoon olive oil in a pan over medium heat. Sauté minced garlic and shallots until fragrant, about 2 minutes. Add sliced mushrooms and cook until golden brown and moisture has evaporated, approximately 5-7 minutes.
- Prepare the Tart Base: Roll out the thawed puff pastry on a baking sheet lined with parchment paper. Score an outline around the edges about 1 inch from the border to create a raised crust. Optionally prick the base lightly with a fork to prevent excess puffing.
- Assemble the Filling: In a bowl, combine the roasted butternut squash, sautéed mushrooms, fresh thyme, sage, salt, and pepper. Spoon the mixture evenly onto the prepared pastry, spreading evenly but leaving the edges clear.
- Add Cheese and Bake: Sprinkle grated Parmesan cheese over the filling. Bake in the preheated oven at 400°F (200°C) for 20-25 minutes or until the pastry is golden and crisp and the cheese has melted and slightly browned.
Notes
- Cut the butternut squash into uniform cubes for even roasting.
- Do not overload the tart with filling to prevent soggy crust.
- Use fresh thyme and sage for best flavor.
- Fully thaw puff pastry before rolling to avoid cracking.
- Serve warm or slightly cooled to enjoy the best flavor and texture.
