Before cooking, I always pat the cod fillets completely dry using paper towels. This step helps achieve a crisp sear instead of a soggy surface. I season both sides generously with salt and freshly ground black pepper to bring out the natural flavor of the fish.
I heat olive oil in a skillet over medium-high heat until it shimmers. The cod goes in gently and cooks undisturbed for a few minutes to develop a golden crust. After flipping, I cook the other side until the fish is opaque and flakes easily with a fork.
Using the same pan, I lower the heat and melt the butter. The minced garlic goes in next and cooks just until fragrant, not browned. I then stir in parsley, dill, chives, and fresh lemon juice, letting the sauce come together smoothly.
I return the seared cod to the skillet and spoon the herb butter sauce over each fillet. Letting it simmer briefly allows the fish to soak up all that buttery, herby goodness. Once warmed through, it’s ready to serve.
