Step 1

In a small bowl, whisk together the soy sauce, honey (or brown sugar), rice vinegar, sesame oil, grated ginger, minced garlic, and red pepper flakes (if using).

Step 2

Place the cod fillets in a shallow dish or resealable plastic bag. Pour half of the marinade over the cod, ensuring the fillets are evenly coated. Reserve the remaining marinade for the glaze.

Step 3

Cover and refrigerate the cod for 15-20 minutes.

Step 4

Heat the olive oil in a large skillet over medium heat.

Step 5

Remove the cod from the marinade, letting any excess drip off. Place the fillets in the skillet and cook for 3-4 minutes on one side. Carefully flip and cook for another 3-4 minutes, or until the fish flakes easily with a fork. Remove from the skillet and set aside.

Step 6

In the same skillet, pour in the reserved marinade. Bring to a simmer over medium heat and cook for 1-2 minutes, or until slightly thickened.

Step 7

Spoon the thickened glaze over the cooked cod fillets.

Step 8

Garnish with sesame seeds and chopped green onions. Serve immediately with steamed rice, quinoa, or vegetables.
