Begin by patting the cod fillets dry using paper towels, ensuring no excess moisture remains. This step is crucial for achieving a crisp surface during stir-frying. Season both sides of the fillets generously with salt and freshly cracked black pepper.

In a small bowl, whisk together the olive oil, freshly squeezed lemon juice, minced garlic, and chopped herbs to create a vibrant marinade. Lightly brush or spoon this mixture over both sides of each fillet, allowing the flavors to infuse while the pan heats.

Place a large nonstick or stainless steel skillet over medium-high heat. Once the pan is hot, drizzle in a bit of olive oil to coat the surface lightly. Carefully lay the cod fillets into the skillet, making sure not to overcrowd the pan.

Sear the fillets for 4 to 5 minutes on the first side until the bottom is golden brown and the edges begin to crisp. Gently flip the fillets and continue cooking for another 4 to 5 minutes, or until the fish is fully opaque and flakes easily when tested with a fork.

Transfer the stir-fried cod to serving plates and spoon over any remaining pan juices. Serve immediately with your favorite sides for a quick yet flavorful seafood dish.
