Place each half, cut-side down, on the baking sheet. Bake until you can easily pierce the skin of the squash with a fork or, if you turn the squash over, you can easily get a fork through the squash all the way to the skin. Figure about 40 minutes.☞ TESTER TIP: Size does matter. If you have a small squash, it may cook in as little as 30 minutes. If your squash is very large, it may take as much as 50 minutes.
