How to Make Easy Low Carb Chicken Casserole

Prep and Mix the Base

Preheat your oven to 375°F (190°C). Grease a 9×13-inch casserole dish with nonstick spray or a dab of olive oil.
In a large mixing bowl, combine the shredded chicken, broccoli, red bell pepper, and diced onion. Stir to distribute evenly.

Create the Creamy Sauce

In a smaller bowl, mix together the sour cream, mayonnaise, garlic powder, onion powder, 1/2 cup cheddar, mozzarella, salt, and black pepper until smooth and creamy.
Pour the sauce over the chicken and veggie mixture. Stir thoroughly to ensure everything is coated in luscious, cheesy goodness.

Bake and Serve

Spoon the mixture into your prepared casserole dish, smoothing out the top with a spatula.
Sprinkle the remaining 1/2 cup shredded cheddar over the top.
Bake in the preheated oven for 25-30 minutes, until bubbly and lightly golden on top.
Let it cool for 5 minutes before sprinkling with fresh parsley and serving warm. Enjoy!
