A variety of small squash

Acorn squash is a winter squash with distinctive longitudinal ridges on its exterior and sweet, yellow-orange flesh inside. Although considered a winter squash, acorn squash belongs to the same species as all summer squashes. As the name suggests, its shape resembles an acorn. Acorn squashes typically weigh one to two pounds and are between four and seven inches long.

If you can’t find acorn squash, don’t worry, it would work just as well in any small pumpkin or squash. The photo above is some of the ones I found in my local supermarket.

Imagine serving up these tasty stuffed acorn squashes for Thanksgiving or Christmas dinner. They will add a unique touch to your table plus they provide their own dish! And of course, they taste amazing!





Oh, and acorn squash seeds can be seasoned and toasted, just like pumpkin seeds. Reserve the seeds while preparing this recipe to enjoy as a healthy snack later.
