Preheat oven to 400°F (200°C). Line a large rimmed baking tray with parchment paper.
Toss squash slices with olive oil, thyme, salt, and pepper. Arrange in a single layer on the tray and sprinkle with Parmesan.
1 (2 lb / 900 g) acorn or delicata squash, 2 tbsp (30 ml) olive oil, 8 sprigs fresh thyme, ½ tsp (3 g) kosher salt, ¼ tsp (1 g) black pepper, ¼ cup (25 g) freshly grated Parmesan cheese
Roast 20–30 minutes, until the centers are tender and the edges are golden.

Notes
Delicata squash works in place of acorn and doesn’t need peeling.
Freshly grated Parmesan melts and crisps better than pre-shredded.
Slice the squash evenly so it all roasts at the same pace.
Reheat leftovers in the oven at 350°F or add cold cubes to salad.
