Ingredients and Variations

ACORN SQUASH: Start with firm and heavy acorn squashes that smell slightly sweet at the base. Save the seeds because they can be roasted just like pumpkin seeds!

SEASONINGS: Parmesan cheese is the tangy complement to the sweet and nutty flavor of the acorn squash. For a more festive dish, sprinkle on a little brown sugar or even some Pumpkin Pie Spice or Apple Pie Spice. Drizzle acorn squash with honey or maple syrup before roasting and let the sugars caramelize onto the flesh and skin.
