Pat chicken dry, then season all sides with salt, pepper, and paprika.
Heat olive oil in a large skillet over medium-high. Sear chicken 4–5 minutes per side until golden. Set aside.
Lower heat, melt butter in the same pan. Add garlic and cook until fragrant (1–2 min).
Stir in mustard, red pepper flakes, parsley, and dill.
Add lemon juice, broth, and cream. Stir, simmer 2–3 minutes until sauce melds.
Return chicken to skillet, coat with sauce, cover, and cook 8–10 minutes until internal temp reaches 165°F (74°C).
Garnish with extra parsley. Serve hot over rice, bread, pasta, or veggies.
