Because of their size and shape and when cut in half from the top down they look like little “edible bowls,” just waiting to be filled with something wonderful like this Quinoa, Feta and Pistachio-Stuffed Acorn Squash!

Inspired by a recipe in Meatless, Martha Stewart cookbook, I added some things that just seemed natural to add such as lemon, garlic and a hint of onion flavor in the form of chives.

Besides being an elegant meatless meal for two, this stuffed acorn squash is also a healthful one.  Acorn squash is high in vitamin C, which may help fend off the cold virus. Quinoa and nuts are considered “superfoods.”

Tips for buying acorn squash:

When selecting squash, it should feel heavy for the size, which means it has plenty of moisture.  I like to buy acorn squash with a “flash” of orange on it; it always seems to be the perfect ripeness.

Tips for cooking quinoa:

Although I frequently cook quinoa for clients, I’ve found it challenging to get it “just right” following package instructions.  Most have you rinse it (to remove the bitter coating known as saponin), add to boiling water, reduce the heat, cover and simmer for 15 minutes.  My result was generally undercooked quinoa with water remaining in the pot.

The method I’ve found works best is:

  • Leave the cover off while it’s simmering so I can watch it.
  • After about 12-15 minutes when much of the water has been absorbed or cooked out and the “germ” begins to appear, I then cover and let it stand off the heat for 12 to 15 minutes.
  • Quinoa is cooked when the germ has been fully released and it’s fluffy and tender.

If you’d rather not go to the trouble, fully cooked quinoa is now available in the freezer section near the vegetables at many grocery stores.

If you prefer, couscous or orzo may be substituted for the quinoa.  Serve with sauteed greens or a green salad for a delicious plant-based meal!

  1. I made the quinoa, feta, pistachio stuffed acorn squash for the first time. Followed the recipe as posted. Very delicious, healthy clean eating meal. Had it as our main with a garlic herb tortilla to accompany. I found the quinoa was a bit dry and needed something to spice it up. The fresh lemon was awesome as well as the chives. We love feta. I think next time i might add more feta and some on the top and place under the broiler?? Also may add crumbled cooked bacon into the quinoa mix.
    Overall we would give this recipe an 8 out of 10👍
