Lightly butter a 3-quart baking pan/dish and set aside.
Combine cauliflower rice and shredded chicken in a large mixing bowl.
Add paprika, garlic powder, onion powder, Italian Seasoning, dried oregano, and chili powder; mix to combine.
Add heavy cream, softened cream cheese, half of the shredded cheddar cheese, garlic, salt, and pepper; stir until everything is thoroughly incorporated.
Transfer mixture to previously prepared baking pan and cover with aluminum foil.
Bake for 30 minutes.
Remove foil; add remaining shredded cheddar cheese and continue to bake for 10 more minutes, or until the top is browned, and the mixture is bubbly and cheese is melted.
