In a large skillet, heat olive oil over medium heat. Add the chicken pieces and season with salt and pepper. Cook until browned and cooked through, about 7-8 minutes. Remove from skillet and set aside.
In the same skillet, add minced garlic and red pepper flakes (if using). Sauté for about 1 minute until fragrant.
Pour in the chicken broth and white wine, scraping the bottom of the skillet to deglaze. Allow the mixture to simmer for 2-3 minutes.
Return the cooked chicken to the skillet and stir in fresh lemon juice. Keep warm over low heat while preparing the rice.
In a medium saucepan, combine 2 cups of chicken broth and bring to a boil. Add the Arborio rice, reduce heat to low, cover, and cook for about 18-20 minutes until rice is tender and creamy.
Once the rice is cooked, stir in heavy cream and Parmesan cheese until well combined. Season with salt and pepper to taste.
Serve the creamy garlic Parmesan rice topped with the chicken scampi mixture. Garnish with chopped parsley.
