I was getting ready to post a similar recipe, but baked at 375 for 45 minutes instead of microwaved. My recipe has 1 cup mushrooms, 1/2 cup celery and 1/4 cup scallions, and 1/2 cup sour cream and 1/4 cup grated Parmesan. After the veggies, sour cream and parmesan are stirred into the sausage filled into the squash it bakes 10-15 more minutes. Also, if you have trouble cutting through the hard squash, as I sometimes do, I've found it helpful to put the acorn squash in the oven whole for 5-10 minutes, which will warm it up enough to soften the outer rind so that you can cut it. It is probably a good idea to set it on a cookie sheet or in pan in case there are any pricks in the rind that might ooze a little liquid.
This was great! I halved the recipe and added in some chopped mushrooms and 1/4 t. rubbed sage. I also used 1 sweet italian turkey sausage for the meat. It was delicious and I can't wait to make it again.
This was so fast and easy to make. I made 1/2 recipe for DH and I. It would not have all fit in my microwave at once (maybe plan double the time for cooking if doing whole recipe). Used plain yogurt instead of sour cream for DH, but I liked mine with the sour cream better. Was a bit too sausagey towards the end of the meal for me, might do 1/2 ground turkey, 1/2 sausage next time, but it was still good. Thanks!
