This easy Gluten-Free Chicken Butternut Squash Casserole is low-carb comfort food at it’s finest. Made with boneless chicken breasts, spiralized butternut squash and a creamy garlic mushroom sauce, you’ll be coming back for seconds. You’ll never miss having pasta in this hearty, satisfying dish.
One-dish meals are the best, especially when they involve cheese. I like to make life easier by cooking everything in one dish for convenience. I have a few more favorite one-dish meals on the blog, like this Greek Chicken Stew (a must try!), Spaghetti Squash Meatball Casserole (also a family favorite), and a healthier Chicken Vegetable Casserole that’s packed with a LOT of veggies. There are plenty more, just to name a few.
I used to make a version of this chicken casserole recipe that involved egg noodles, but I wanted to switch up the pasta with a nutrient-dense vegetable and reduce the carbohydrates since there is more fat in this dish (why it tastes SO good ;). I knew that butternut squash would hold up well in a baked dish and the results were amazing. We declared this creamy gluten-free chicken butternut squash casserole a winner, winner, chicken dinner!
This recipe makes eight generous servings at only 273 calories each. I like to serve this dish with steamed broccoli or a side salad. It would also be amazing over cauliflower mashed potatoes.
