The weather is cooling down and I’ve been craving lots of fall flavors! With squash in season, this vegetarian stuffed squash is the perfect way to make use of sweet winter squash.

What’s the best type of squash for this recipe?

Winter squash is best for roasting. Look for a small sweet squash like acorn squash, sweet dumpling squash, or carnival squash. I used carnival squash which is actually a hybrid between acorn and sweet dumpling squash. I love how colorful it is!

Substitution Ideas

  • You can use any small, sweet winter squash, so if you can’t find a carnival squash, try acorn squash or sweet dumpling squash. You could even use a small kabocha squash.
  • If you don’t have walnuts, you can use pecans instead.
  • If you don’t have dried cranberries, try dried cherries or chopped dried apricots.
  • To make this recipe vegan you can skip the Parmesan cheese or add a little nutritional yeast instead. You may need to add a bit more salt if you skip the Parmesan cheese.
