Prep the chicken: Slice each chicken breast horizontally to create 4 cutlets. Pat dry. Season both sides with salt, pepper, paprika, and garlic powder.
This helps with browning and flavor.
Sear for color: Heat a large skillet over medium-high. Add olive oil. When shimmering, add chicken in a single layer.
Sear 3–4 minutes per side until golden. Transfer to a plate. The chicken will finish cooking in the sauce.
Build the flavor base: Lower heat to medium.
Add garlic and sliced sun-dried tomatoes. Sauté 30–60 seconds until fragrant. Stir in tomato paste and cook another 30 seconds to caramelize slightly.
Deglaze: Pour in chicken broth, scraping up any browned bits.
Bring to a gentle simmer. Those bits add big flavor.
Make it creamy: In a small bowl, whisk Greek yogurt with heavy cream to smooth it out. Optionally whisk in cornstarch for a thicker sauce.
Stir this mixture into the skillet until combined and just starting to simmer.
Add the cheese and heat: Reduce heat to low. Stir in Parmesan and red pepper flakes. Let the sauce gently bubble for 2–3 minutes until slightly thickened.
Finish the chicken: Return chicken and any juices to the skillet.
Spoon sauce over the pieces. Simmer on low 3–5 minutes, until the chicken reaches 165°F internally and the sauce is silky.
Brighten and serve: Stir in chopped basil. Taste and adjust salt and pepper.
Serve with extra basil and a squeeze of lemon if you like. Pair with whole-grain pasta, cauliflower rice, or steamed greens.
