Step 1

Preheat the oven to 400 degrees F (200 degrees C). Line a large baking sheet with aluminum foil.

Step 2

Combine squash, olive oil, brown sugar, sea salt, cinnamon, and cayenne pepper in a large bowl; toss until squash is evenly coated. Spread squash in an even layer onto the prepared baking sheet.

Step 3

Roast in the preheated oven, turning midway through, until edges are lightly browned and centers are tender, 40 to 45 minutes. Transfer to a serving dish and garnish with nuts.
