Prep the chicken: Pat chicken dry. Season both sides with 3/4 teaspoon salt, pepper, and garlic powder.
This helps build a flavorful crust.
Sear the chicken: Heat olive oil and butter in a large skillet over medium-high. When hot and shimmering, add chicken in a single layer. Sear 3–4 minutes per side until golden and nearly cooked through.
Transfer to a plate.
Sauté the garlic: Lower heat to medium. Add minced garlic to the skillet. Stir for 30 seconds, scraping up browned bits.
Deglaze: Pour in chicken broth.
Simmer 1–2 minutes to reduce slightly. Those browned bits add deep flavor to the sauce.
Make it creamy: Reduce heat to low. Whisk in pesto, Greek yogurt, and light cream until smooth.
Keep it gentle—don’t let it boil to prevent curdling.
Thicken and season: Stir in Parmesan. Simmer on low for 1–2 minutes until the sauce lightly thickens. Taste and add the remaining 1/4 teaspoon salt if needed.
Finish the chicken: Return chicken and any juices to the pan.
Spoon sauce over the cutlets. Simmer 2–3 minutes, or until chicken reaches 165°F in the thickest part.
Brighten it up: Stir in lemon juice for balance. Add a pinch of red pepper flakes if you like heat.
Serve: Top with chopped basil and extra Parmesan.
Spoon plenty of sauce over each piece.
