Heat olive oil in a large skillet over medium heat. Season chicken with salt, pepper, paprika, and Italian seasoning. Sear until golden brown and cooked through. Remove and set aside.
In the same skillet, melt butter and sauté onion and garlic until softened and fragrant.
Add rice to the pan and stir for 1–2 minutes to develop flavor.
Pour in chicken broth, milk, and heavy cream. Stir well, bring to a simmer, cover, and cook for 18–20 minutes until the rice is tender.
Stir in Parmesan cheese until it melts into a creamy sauce.
Return chicken to the skillet, mix gently, and cook for 2 more minutes to warm through.
Garnish with fresh parsley and serve hot.
