Season and sear the chicken:
Pat chicken dry and season with salt, pepper, garlic powder, and onion powder. Heat olive oil or butter in a large skillet over medium heat. Sear the chicken for 3–4 minutes per side until golden brown. Remove and set aside.
Sauté aromatics:
In the same pan, add the chopped onion and minced garlic. Sauté until soft and fragrant, about 2–3 minutes.
Toast the rice:
Stir in the uncooked rice and let it toast lightly for 1 minute to absorb flavor.
Add liquids:
Pour in chicken broth, milk (or heavy cream), and Italian seasoning. Stir well.
Simmer:
Return the chicken to the pan. Cover and cook on low heat for 20–25 minutes, or until the rice is tender and the chicken is cooked through.
Make it creamy:
Stir in sour cream and shredded cheese until melted and creamy. Adjust salt and pepper to taste.
Serve:
Garnish with chopped parsley and serve warm.
