Creating this Low Carb Chicken Casserole is easy when you follow these steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C).
2. Cook Chicken: If you haven’t already, cook and shred the chicken. You can use rotisserie chicken for convenience.
3. Prepare Vegetables: Wash and chop the broccoli florets into bite-sized pieces. If using frozen cauliflower rice, thaw it and drain any excess moisture.
4. Mix Ingredients: In a large mixing bowl, combine the shredded chicken, broccoli, cauliflower rice, and half of the cheddar cheese.
5. Make Sauce: In another bowl, whisk together the heavy cream, eggs, garlic powder, onion powder, salt, black pepper, and paprika until well combined.
6. Combine Mixtures: Pour the cream mixture over the chicken and vegetable mixture. Stir until everything is evenly coated.
7. Transfer to Casserole Dish: Grease a 9×13 inch casserole dish with olive oil. Pour the mixture into the dish and spread it evenly.
8. Add Cheese: Sprinkle the remaining cheddar cheese over the top of the casserole.
9. Bake: Place the casserole in the preheated oven and bake for 35-45 minutes or until the top is golden brown and the casserole is set.
10. Cool and Garnish: Once baked, remove the casserole from the oven and allow it to cool for a few minutes. Garnish with chopped green onions before serving.
