Season both sides of chicken breasts with salt, pepper, and paprika.
Heat olive oil in large skillet over medium-high heat until shimmering. Add chicken and sear 4-5 minutes per side until golden brown. Remove and set aside.
Lower heat to medium. Add minced garlic and cook 30 seconds, stirring constantly.
Add sun-dried tomatoes and cook 1 minute to release flavors.
Pour in chicken broth and scrape up browned bits from bottom of skillet.
Add heavy cream, Parmesan cheese, red pepper flakes, Italian seasoning, and butter. Stir and simmer 2-3 minutes until slightly thickened.
Return chicken to skillet, spooning sauce over top. Simmer 5-7 minutes until chicken reaches 165°F internal temperature and sauce is rich and creamy.
Let rest 2-3 minutes. Garnish with fresh basil or parsley and serve immediately.
Notes
Use chicken thighs for juicier meat. They may need extra 2-3 minutes cooking time.
Fresh grated Parmesan melts smoother than pre-shredded cheese.
Deglaze with white wine instead of chicken broth for extra depth.
For lighter version, use half-and-half, but sauce won’t be as rich.
