Step 1: Pat the cod fillets dry with paper towels and season both sides with salt and black pepper.

Step 2: Heat olive oil in a large skillet over medium heat. Add the cod fillets and cook for 2-3 minutes per side until lightly browned. Remove and set aside.

Step 3: In the same skillet, melt the butter over medium heat. Add the minced garlic and cook for 1-2 minutes until fragrant.

Step 4: Stir in the lemon juice, lemon zest, chicken broth, and red pepper flakes (if using). Let the sauce simmer for 2-3 minutes.

Step 5: Return the cod fillets to the skillet and spoon the sauce over them. Cook for another 3-4 minutes until the fish is cooked through.

Step 6: Sprinkle with fresh parsley and serve immediately with additional lemon wedges if desired.
