Nutrition: this casserole has 8 servings. Each serving is about 1.25 cups and has 3 NET carbs. I just eye up portions as I serve. For a more exact measurement weigh your casserole dish empty and then full. Divided the difference by 8 for the weight of each portion.

Substitutions: you can swap the shredded chicken for shredded turkey. It’s great to use leftover turkey from the holidays. You can swap in any cooked low carb vegetable for the spaghetti squash. Broccoli, cauliflower, spinach, and zucchini all work very well.

Prep Time: you’ll need to cook the chicken and spaghetti squash ahead of time. This will save time when you are preparing the casserole. 

To Reheat: warm the keto creamy chicken casserole in the microwave for 1-2 minutes on a microwave-safe plate. Cover it with a paper towel, so it doesn’t splatter. You can also heat in the oven at 350 degrees for 10-15 minutes or until hot.
