Prepare the Cod: Pat the cod fillets dry with paper towels and season both sides with salt and pepper.
Melt the Butter: In a large skillet, melt 2 tablespoons of butter over medium heat.
Sauté Garlic: Add the minced garlic to the skillet and sauté for about 1 minute until fragrant, being careful not to burn it.
Add Lemon and Thyme: Stir in the lemon zest, lemon juice, and dried thyme to the garlic butter mixture, letting it bubble for 30 seconds.
Cook the Cod: Place the cod fillets in the skillet, cooking for about 3-4 minutes on each side. If the cod starts to flake easily with a fork, it’s ready. Pour the remaining melted butter over the fillets as they cook.
Garnish and Serve: Once cooked, remove from heat and garnish with fresh parsley. Serve immediately with lemon slices on the side.
