Preheat your oven to 425°F (220°C).

Slice the delicata squash in half lengthwise and scoop out the seeds using a spoon.

Slice the squash into half-moons, about ½ inch thick.

Thinly slice the onion into rounds.

In a large bowl, combine the squash and onion slices. Drizzle with olive oil, and sprinkle with salt and pepper.

Toss everything together to ensure even coating.

Spread the seasoned vegetables in a single layer on a baking sheet.

Roast for about 20–25 minutes or until the squash is tender and the onions are crisp. Drizzle with maple syrup during the last 5 minutes of roasting.

Garnish with fresh herbs before serving.
