There is nothing like Fall cooking. The sweet and savory spices, the casseroles, the soups, the assortments of squash fill the air and the tables with warmth and comfort. This chicken and mushroom stuffed acorn squash is the perfect fall recipe to warm your tummy.

Acorn squash is green on the outside, orange on the inside and shaped like an acorn. It has a mild flavor and it is extremely easy to cook with. Cut it in half, scoop out the seeds and roast it. The squash is very versatile. It can be used for:

  • savory dishes stuffed with all sorts of things like rice, veggies, and meat
  • be used in soups
  • made sweet by adding maple syrup or honey
  • roasted as a side dish

Any which way you decide to cook it, it will be delicious!

For the recipe I used chicken breasts, mushrooms, sweet onion, and sage. The fresh sage added into the chicken mixture adds to the warmth of the dish and as a plus makes your kitchen smell good. This recipe can easily be made vegetarian.

The squash I used were on the smaller size so I bought three. Since they were a little small I had filling left over so I put it on the table and we just added it to our plates. It works out just fine and it gets all eaten up. If you use larger squash then all the filling will should fit. If not, just put it a bowl and place it on the table.

To roast the squash, cut off the stem and then cut in half lengthwise, scoop out the seeds and place on a baking sheet. Brush with olive oil and sprinkle with salt in pepper. Turn the squash over, so the cut side is down and place in the oven.

While the squash is roasting prepare the filling. This is a meal that can be made in 35-40 minutes. If you have leftovers that’s ok, that means you have lunch for tomorrow.

    1. Thanks for pinning! It is sure to warm you up. I can’t wait to start making more cool weather recipes, too. It’s been so hot here in Southern California that I’ve just been making salads. Looking forward to the hearty soups.
