Spaghetti squash casserole is a healthy, gluten-free and low carb dinner, replacing traditional pasta casserole recipes. This easy gluten-free casserole recipe uses turkey sausage and mushrooms, making it a healthier version of baked ziti.
It’s Improv Challenge day for March, and this month everyone is cooking up recipes using sausage and mushrooms. I’m guessing there won’t be any desserts this time around. My inspiration was the classic baked ziti, with all of its saucy, cheesy goodness, and stepped it up a bit in flavor and nutrition. Whether you want leftovers to put in the freezer or have to feed a crowd, you’ve gotta try this Turkey Sausage and Mushroom Spaghetti Squash Casserole.
