Ingredients
- For the Grilled Mackerel:
- 2 whole fresh mackerel, cleaned and butterflied (about 1 lb each)
- 2 tbsp olive oil
- 1 tsp sea salt
- 1/2 tsp freshly ground black pepper
- 1 lemon, sliced thinly
- For the Zesty Mustard-Dill Sauce:
- 3 tbsp Dijon mustard
- 2 tbsp fresh dill, finely chopped
- 1 tbsp honey
- 1 tbsp apple cider vinegar
- 2 tbsp extra virgin olive oil
- 1 garlic clove, minced
- Salt and pepper, to taste
Instructions
- Prepare the Mackerel: Rinse the mackerel under cold water and pat dry with paper towels. rub the fish inside and out with olive oil, salt, and pepper. Place thin lemon slices inside the cavity for an aromatic lift during grilling.
- Preheat Your Grill: Get your grill hot with a medium-high flame. Clean and oil the grates thoroughly to prevent sticking. A temperature of around 375°F (190°C) works beautifully for even cooking.
- Marinate the Sauce: In a bowl, whisk together Dijon mustard, chopped dill, honey, apple cider vinegar, olive oil, and garlic. Adjust salt and pepper according to your taste. Let it rest so the flavors meld perfectly.
- Grill the Mackerel: Place the mackerel skin-side down on the grill. Cook for 5 to 6 minutes without moving, allowing a crisp, flavorful skin to develop. Carefully flip and grill the other side for another 5 to 6 minutes, checking for opaque, flaky flesh.
- Rest Before Serving: Transfer the grilled mackerel to a plate and let it rest for 3 minutes to seal in the juices.
- Serve: Generously spoon the zesty mustard-dill sauce over the fish or serve it on the side for dipping. Garnish with extra dill sprigs and lemon wedges for a vibrant touch.
Tips for Success
- Choosing Mackerel: Opt for fresh,firm mackerel with bright eyes and shiny skin. Avoid fish with any unpleasant odor-it should smell like the sea,fresh and clean.
- Skin Crispiness: Pat the fish thoroughly dry before oiling and placing on the grill to ensure the skin crisps up beautifully without tearing.
- Make-Ahead Sauce: The mustard-dill sauce can be made up to 24 hours ahead and stored in the refrigerator to deepen the flavors.
- Alternative Cooking Methods: if grilling isn’t an option, broil the fish skin-side up in the oven on high heat for about 8-10 minutes, watching closely to avoid burning.
- Substitutions: Greek yogurt can be added to the sauce for creaminess, or swap dill with fresh parsley for a lighter herbaceous note.
Serving Suggestions to Complement and Enhance Your Grilled Mackerel
Pair your grilled mackerel with a crisp cucumber and radish salad dressed lightly in lemon juice and olive oil. For a heartier side, grilled asparagus or roasted new potatoes make excellent companions. A chilled glass of dry white wine, such as Sauvignon Blanc or Pinot Grigio, beautifully accentuates the bold flavors. Garnish each serving plate with fresh dill and thin lemon slices to enhance both aroma and presentation.
