Preheat an oven to 400°F.
Wash and halve the delicata squash, scoop out the seeds, then slice the squash into ¼-inch half moons.
Place the squash on a large baking sheet, drizzle with oil and season with a pinch of salt. Toss the squash to coat.
Roast the squash for 15 minutes, flip, then roast for another 15-20 minutes or until the squash is caramelized and tender.
Remove the pan of squash from the oven and set aside.
In a small skillet, heat up the butter and miso until hot and bubbly. Pour the butter over the squash and toss to coat. Serve the squash while hot. Enjoy!
