Keep squash pieces as stable as possible while cutting. A rubber mallet can help, if you have one, to gently push the knife through difficult thick spots. Using a very sharp vegetable peeler, one with a carbon steel blade, will help with the peeling.
By the way, it helps to microwave a butternut squash (whole) for 30 seconds or so first, before peeling. This will help soften the peel just enough to make it a bit easier to peel.
- One butternut squash, 1 1/2 to 3 pounds
- A sharp, heavy, chef's knife
1 Slice off the ends: Using a heavy, sharpened chef's knife, cut off about 1/4-inch from the bottom of the squash in an even slice. Then cut off 1/4-inch from the stem end.
2 Peel with a vegetable peeler: Holding the squash in one hand, use a sharp vegetable peeler in the other hand to peel off the outer layer of the squash. You can also secure the squash standing upright and peel it in downward strokes with the peeler.
3 Cut the squash in half: Stand the peeled squash upright on a cutting board. It shouldn't wobble, you want the squash to be stable. (If it is wobbly, make another cut at the bottom to even it out.) Make one long cut, down the middle from the top to bottom, with a heavy chef's knife.
Some squashes can be pretty hard; to help with the cutting you can use a rubber mallet to gently tap on the ends of the knife to help push the knife down through the squash.
4 Scrape out the seeds: Use a metal spoon to scrape out the seeds and the stringy pulp from the squash cavity. (If you want, you can prepare the seeds like toasted pumpkin seeds.)
5 Cut squash halves into slices: Lay the squash halves, cut side down on the cutting board for stability. Working section at a time, cut the squash into slices, lengthwise, the desired width of your squash pieces. Some recipes call for 1/2-inch slices or cubes, some for 1-inch or greater.
6 Stack and slice, then make crosswise cuts into cubes: If you are cubing the squash, lay the slices down (you can stack a few at a time) and make another set of lengthwise cuts. Then make crosswise cuts to make cubes.
One 1 1/2 pound butternut squash will yield approximately 4 cups of 1/2-inch cubed squash.
