Preheat the Oven:
Preheat your oven to 350°F (180°C).
Season the Chicken:
Pat chicken thighs dry. Season both sides with salt, pepper, and lemon zest.
Sear the Chicken:
Heat olive oil in a cast iron skillet over high heat.
Add chicken thighs and sear for 3–4 minutes per side, until golden brown.
Remove chicken from skillet and set aside.
Sauté Aromatics:
Lower heat to medium. Add minced garlic and oregano to the skillet. Sauté for 2–3 minutes until fragrant.
Build the Sauce:
Add chicken stock, sun-dried tomatoes, and lemon juice. Bring to a simmer for 1–2 minutes.
Stir in heavy cream and Parmesan cheese until melted and sauce is slightly thickened.
Bake:
Return chicken thighs to the skillet, spoon sauce over the top.
Transfer skillet to the oven and bake for 15 minutes, or until chicken is cooked through (internal temp 165°F/74°C).
Finish and Serve:
Let rest 5 minutes. Top with crumbled feta and fresh parsley.
Serve hot, with extra sauce spooned over chicken. Optionally, pair with cauliflower rice or a fresh salad.
