Oven Roasted Parmesan Acorn Squash

Published by Cheryl Mussatto, MS, RD, LD on Oct 10, 2018

Nothing quite says ‘Autumn is here’ like winter squash.  Whether its butternut, spaghetti, pumpkin, acorn or many other varieties of these versatile vegetables, each one has its own unique characteristics and flavors they offer. Typically, the norm is to sweeten up squash’s rather bland and banal flavor. Who of us has not added in brown sugar, honey or maybe maple syrup providing a hint of sweetness?

That’s why I wanted to test out this recipe for Oven Roasted Parmesan Acorn Squash – a more savory version than the usual sugary squash recipes typical on dinner tables.

This recipe couldn’t be easier to prepare and this is as good as acorn squash gets!  Simply scrumptious!  You may think your family will prefer the sweetened version of acorn squash but I disagree.  Consider it a more “grown-up” alternative to the usual.

The nice thing about acorn squash is its broad diversity of nutrients.  But it’s particularly bountiful in vitamin C, providing a healthy boost to the immune system.  Vitamin C has the power to stimulate the production of white blood cells defending the body from disease-causing microbes.  Also acting as an antioxidant, vitamin C may be of benefit in protecting the body from chronic conditions such as heart disease and cancer.

Look for acorn squash with ridged, dark-green skin free of blemishes and heavy for its size. Its sturdy exterior allows it to be stored at room temperature for up to one month or longer it kept in a cool, dark place.

So, plan on trying out this recipe for acorn squash and the rave reviews that will follow.
