To make it easier to cut butternut squash, microwave it for 1-2 minutes to slightly soften the flesh. Then slice off the stem from the top. Use a sharp vegetable peeler to peel the squash until the flesh is vibrant orange. Slice the squash in half, horizontally. Then cut the rounded bottom portion of the squash in half, and scoop out the seeds with a spoon. Cut the bottom halves into wedges, then cube. Slice the top half of the squash in half, vertically. Finally, cut the halves into spears, then cube.
