Many people will be cooking winter squash for the holidays. Use your instant pot, and get the job done quickly and efficiently!
Or you can cube it, which might work better for butternut, jarrahdale, sweat meat or blue hubbard which are those larger denser squash varieties. For all methods, add 1 cup water to the instant pot.
For cubed squash, peel and seed the squash or pumpkin, cut into 1" cubes, add to pressure cooker on steamer basket. Cook on high pressure for 3 minutes if you want them to hold their shape. Then do a quick release.
