Slice off ends, and then slice squash in half lengthwise. Scoop out seeds (and save for roasting for snacks or salad topping!).
Slice into 1/4″-1/2″ thick slices. Toss (directly on baking sheet) with some oil, spices, salt & pepper. My favorite combo for delicata squash is melted coconut oil, chili powder, cumin, and a little bit of salt. .
Cook at 425 degrees for 20-30 minutes, turning over once halfway through. Timing will vary, so watch carefully.
