Description
A savory tart featuring sweet caramelized onions and roasted butternut squash on a flaky crust.
Ingredients
Scale
- 1 sheet puff pastry, thawed
- 1 medium butternut squash, peeled and diced
- 2 large yellow onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon butter
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/4 cup heavy cream
- 1 large egg
- 1/4 cup grated Parmesan cheese
Instructions
- Preheat your oven to 400°F (200°C).
- Toss the diced butternut squash with 1 tablespoon of olive oil, salt, and pepper. Spread on a baking sheet and roast for 15 minutes until slightly tender. Set aside.
- In a skillet over medium-low heat, melt the butter with the remaining 1 tablespoon of olive oil. Add the sliced onions. Cook slowly for 20 to 25 minutes, stirring occasionally, until deeply browned and sweet.
- Roll out the puff pastry sheet to fit a 9-inch tart pan or line a baking sheet. Trim the edges if necessary.
- In a small bowl, whisk together the heavy cream, egg, and Parmesan cheese.
- Spread the caramelized onions evenly over the pastry base. Top with the roasted butternut squash pieces.
- Pour the cream mixture over the squash and onions.
- Bake for 25 to 30 minutes, or until the crust is golden brown and the filling is set.
- Let the tart cool for 10 minutes before slicing and serving.
Notes
- For easier slicing, chill the tart for 15 minutes after baking before cutting.
- You can substitute Gruyère cheese for Parmesan if you prefer a sharper flavor.
