How to Make Keto Chicken Parmesan Casserole

Preheat the oven to 350°F (175°C). This step ensures your casserole bakes evenly, creating that golden brown, bubbling perfection.
Prep the chicken by cutting it into bite-sized pieces. This allows for quicker cooking and makes serving easier once it’s all baked together in the casserole.
Mix the ingredients in a bowl: combine the chicken, marinara sauce, mozzarella cheese, parmesan cheese, eggs, zucchini noodles, garlic powder, and Italian seasoning. Stir until everything is well-coated and evenly combined.
Transfer the mixture to a greased casserole dish. Spread it out evenly, pressing down gently to help the layers meld together while baking.
Bake uncovered for 30-40 minutes. Look for a golden top and bubbling sauce around the edges to catch that deliciously cooked magic!
Garnish with fresh basil and crushed red pepper flakes just before serving. Allow it to cool for a few minutes, then dish it up and enjoy!
