01 - Pat cod fillets completely dry with paper towels. Season both sides generously with salt and black pepper.
02 - Lightly coat each fillet in flour, shaking off any excess to ensure a thin, even layer.
03 - In a large skillet over medium-high heat, warm olive oil with 1 tablespoon butter until foaming subsides.
04 - Add fillets to the hot pan. Cook for 2–3 minutes per side until golden brown and just cooked through. Transfer to a plate and tent loosely with foil.
05 - Reduce heat to medium. Add remaining butter and minced garlic to the skillet. Sauté for 30 seconds until fragrant, being careful not to burn the garlic.
06 - Pour in white wine, scraping up any browned bits from the bottom with a wooden spoon. Simmer for 1 minute to reduce slightly.
07 - Add lemon juice, capers, and chicken broth. Simmer for 2–3 minutes until sauce begins to reduce and flavors meld.
08 - Return cod fillets to the skillet. Spoon sauce generously over each fillet. Heat through for 1–2 minutes.
09 - Sprinkle with fresh chopped parsley and garnish with lemon slices if desired. Serve immediately while hot.
