Season chicken breasts with salt, black pepper, smoked paprika, and red pepper flakes. Heat olive oil in a skillet over medium-high heat and cook chicken for 5-6 minutes per side, or until fully cooked. Remove from heat, let rest, then slice into bite-sized pieces.

Pour in heavy cream and stir well. Let simmer for another 2 minutes until slightly thickened. Add Parmesan cheese, stirring until melted and smooth. If needed, add a splash of reserved pasta water for consistency.
