Corsican Greens Pie with Butternut Squash and Three Cheeses

This vibrant Corsican greens pie is a sophisticated yet simple vegetarian dish that celebrates the earthy flavours of Swiss chard and sweet butternut squash. Inspired by Mediterranean herb tarts, it combines a trio of cheeses—salty feta, sharp Pecorino, and creamy ricotta—with fresh mint and parsley for a bright, aromatic finish. The golden puff pastry provides a crisp, buttery base that contrasts beautifully with the tender, ribboned squash and toasted pine nuts.

Ideal for a light lunch or a seasonal supper, this versatile savoury tart can be served warm from the oven or at room temperature. The inclusion of nutrient-dense greens makes it a wholesome choice for a midweek meal, while the elegant presentation ensures it is impressive enough for weekend entertaining. Serve with a crisp green salad to balance the rich, cheesy filling.

  • 2 tablespoons plus 1 teaspoon olive oil, divided, plus more for drizzling

  • 1/2 small red onion, thinly sliced (about 3/4 cup)

  • 3 celery stalks with leaves, thinly sliced (about 180ml )

  • 1 bunch Swiss chard (about 230g ) or mix of other greens like kale, beet tops, turnip tops, or spinach, stemmed, leaves coarsely chopped, and stalks sliced 1/2-inch thick

  • Salt

a large sauté pan over medium-high heat, heat 2 tablespoons oil. Add onion, celery, chard stems, 1/4 teaspoons salt, and a hearty grind of black pepper and cook until softened, about 5 minutes.
