Gather all ingredients and equipment before starting to ensure a smooth cooking process.

Pat the arctic char fillets dry with paper towels and season both sides with salt and pepper.

Heat a large skillet over medium heat and add the olive oil, swirling to coat the pan.

Add the minced garlic to the skillet and sauté for about 30 seconds until fragrant.

Carefully place the seasoned arctic char fillets skin-side down in the skillet and cook for 4-5 minutes without moving.

Gently flip the fillets and immediately pour the lemon juice and sprinkle the lemon zest over the fish.

Continue to cook the fillets for an additional 3-4 minutes until the fish flakes easily with a fork.

Transfer the fish to a serving platter, sprinkle with chopped parsley, and let it rest for 1 minute before serving.
