Preheat your oven to 425°F
Wash and prep the delicata squash. Cut it into ¼ inch rings and then scoop out the seeds in the middle.
Line a baking sheet with parchment paper and place the delicata squash onto the sheet. Drizzle over the oil and the harissa powder and mix it all together until the delicata squash is evenly coated.
Lay the delicata squash out on the baking tray and make sure the rings aren't touching each other.
Bake at 425°F for 20 minutes, flip the rings over, and bake for 15 more minutes.
Serve hot and enjoy!
