Mix flour and seasonings: In a small mixing bowl whisk together flour, paprika, onion powder, thyme, oregano, cayenne pepper, salt and pepper.
Spread mixture over cod: Sprinkle and spread flour mixture over both sides of the cod fillets (use up all of the mixture).
Heat fats in skillet: Melt 1 Tbsp butter and 1 Tbsp olive oil in a skillet over medium-high heat.
Cook cod in skillet, transfer: Add cod and sear until golden brown and cooked through on each side, about 4 minutes per side (fish should flake easily with a fork when done). Transfer to serving plates.
Melt remaining butter in skillet: Reduce burner temperature to medium-low. Melt remaining 4 Tbsp butter in same skillet.
Saute garlic: Add garlic and saute just until fragrant and just lightly deepened in color (but not browned), about 15 seconds.
Add liquids to butter: Remove from heat and carefully pour and stir in chicken broth and lemon juice (careful it will steam!).
Pour sauce over cod, garnish and serve: Immediately pour sauce over cod fillets. Sprinkle with parsley and serve warm.
