Pat the chicken dry and season with salt, pepper, paprika, and garlic powder. Lightly coat with flour.
Heat olive oil and butter in a large skillet over medium-high heat.
Sear chicken until golden and crispy on both sides, about 4–5 minutes per side. Remove and set aside.
In the same pan, sauté onion until soft, then add garlic and cook briefly.
Deglaze the pan with chicken broth, scraping up the browned bits.
Stir in cream, thyme, and rosemary. Simmer until slightly thickened.
Return chicken to the pan and simmer for 3–5 minutes.
Serve warm with sauce spooned over the top.
