Steps
1. Pat the mackerel fillet dry with paper towels. Season both sides with salt and black pepper.
2. Heat olive oil in a non-stick skillet over medium-high heat.
3. Place the mackerel fillet skin-side down in the pan and cook for about 4-5 minutes until the skin is crispy.
4. Flip the fillet carefully and cook the other side for 2-3 minutes until cooked through.
5. While the fish cooks, combine minced garlic, parsley, lemon juice, Dijon mustard, and honey in a small bowl to make the sauce.
6. Remove the mackerel from the pan and plate it.
7. Drizzle the lemon herb sauce over the fish and serve with lemon wedges on the side.
