This healthy butternut squash casserole works equally well as a vegetarian main course or a hearty side dish.
To Use Frozen Squash: You can add the frozen butternut squash to the recipe as instructed in step #4, however, you may need to increase the cooking time slightly in step #6 as the frozen squash may excrete excess water as it cooks. Just continue to cook the casserole until almost all of the liquid has been absorbed.
To Use Frozen Spinach: Skip step #1. Thaw one cup of frozen spinach, press out any excess water, and add it to the recipe as per step #3.
To Use Dried Sage: Use 1 teaspoon of dried sage.
