Start by patting your cod fillets dry with a paper towel. This is the secret to achieving that perfect sear! Then, season both sides generously with salt and pepper.

Heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once the oil is hot and shimmering, carefully place the cod fillets in the pan. Let them cook undisturbed for about 4-5 minutes on one side until they develop a beautiful golden crust. Flip and cook for another 4-5 minutes until the fish is opaque and flakes easily with a fork. Once cooked, transfer the fillets to a plate and set aside.

In the same skillet, reduce the heat to medium and add the butter. Let it melt, then toss in the minced garlic and red pepper flakes (if using). Sauté for about a minute, stirring frequently to prevent burning. The aroma alone will have your mouth watering!

Stir in the chopped parsley, fresh lemon juice, and lemon zest, mixing everything together to create a flavorful, zesty butter sauce.

Return the seared cod fillets to the skillet, spooning that garlicky, buttery goodness over the top. Let everything simmer together for about a minute to warm the fish back up and soak in all those incredible flavors.

Plate the cod fillets and drizzle any extra garlic butter sauce over them. Garnish with a little more fresh parsley if you’d like. Serve immediately with your favorite sides!
