Start by patting the cod fillets dry with paper towels. Season both sides of the fillets with salt, black pepper, paprika, onion powder, thyme, oregano, and cayenne pepper. Lightly dust each fillet with all-purpose flour, shaking off any excess.
In a large skillet, heat the olive oil over medium-high heat. Once hot, add 2 tablespoons of the butter. Allow it to melt and foam slightly, which indicates it’s ready for the fish.
Carefully place the seasoned cod fillets in the skillet. Cook for about 3-4 minutes on one side without moving them, allowing a golden crust to form. Flip the fillets and add the minced garlic to the pan. Cook for an additional 3-4 minutes, or until the fish is cooked through and flakes easily with a fork.
Once the cod is cooked, remove it from the skillet and place it on a serving plate. To the same skillet, add the chicken broth and fresh lemon juice. Stir to combine, scraping up any brown bits from the bottom of the pan. Reduce the heat to low and add the remaining butter, stirring until melted and incorporated.
Pour the lemon butter sauce over the cod fillets and sprinkle with chopped parsley for a fresh touch. Serve immediately with your favorite sides, such as steamed vegetables or rice.
