Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine shredded chicken, broccoli, cauliflower rice, and minced garlic.
In another bowl, combine cream cheese and chicken broth until smooth.
Add the cheese, Italian seasoning, salt, and pepper to the cream cheese mixture, stirring until combined.
Pour the cream cheese mixture over the chicken and vegetable blend, stirring to coat evenly.
Transfer the mixture into a greased casserole dish and spread it out evenly.
Sprinkle additional shredded cheese on top if desired.
Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and slightly golden.
Allow the casserole to cool slightly before serving.
