01 - Pat chicken breasts dry with paper towels. Season both sides generously with kosher salt and ground black pepper.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and sear for 4-5 minutes per side until golden brown and nearly cooked through. Transfer to a clean plate and set aside.
03 - Reduce heat to medium. Add minced garlic to the same skillet and sauté for 30 seconds until fragrant, being careful not to burn.
04 - Stir in chopped sun-dried tomatoes, dried Italian herbs, and crushed red pepper flakes. Cook for 1 minute to toast the spices and release flavors.
05 - Pour in chicken broth and bring to a simmer, using a wooden spoon to scrape up any browned bits from the bottom of the pan.
06 - Stir in reduced-fat heavy cream and freshly grated parmesan cheese. Simmer for 2-3 minutes, stirring occasionally, until sauce begins to thicken slightly.
07 - Reduce heat to low. Whisk in Greek yogurt until completely smooth and creamy. Do not allow the sauce to boil at this stage to prevent separation.
08 - Return chicken breasts to the skillet, spooning sauce generously over each piece. Simmer gently for 5-8 minutes until chicken reaches an internal temperature of 165°F.
09 - Sprinkle with additional chopped fresh basil. Serve immediately while hot, with extra sauce spooned over each portion.
