📝 About This Recipe

Arctic Char is the sophisticated cousin of salmon and trout, boasting a delicate pink flesh and a rich, buttery flavor that thrives under the high heat of a grill. This recipe highlights the fish's naturally thin, edible skin, which transforms into a crackling, savory crust when seared over open flames. Finished with a zesty, herbaceous gremolata, this dish offers a perfect balance of smoky depth and bright, citrusy acidity.

🥗 Ingredients

The Fish

  • 4 pieces Arctic Char fillets (6-8 oz each, skin-on, pin bones removed)
  • 2 tablespoons Extra virgin olive oil (high quality for brushing)
  • 1 teaspoon Kosher salt (plus more to taste)
  • 1/2 teaspoon Freshly cracked black pepper
  • 1 Lemon (cut into thick rounds for grilling)

Lemon-Caper Gremolata

  • 1/2 cup Fresh flat-leaf parsley (finely chopped)
  • 1 tablespoon Lemon zest (from 1 large lemon)
  • 1 clove Garlic (minced into a paste)
  • 2 tablespoons Non-pareil capers (drained and roughly chopped)
  • 3 tablespoons Extra virgin olive oil
  • 1 pinch Red pepper flakes (optional for subtle heat)

👨‍🍳 Instructions

  1. 1

    Remove the Arctic Char fillets from the refrigerator 20 minutes before cooking to take the chill off, ensuring even cooking.

  2. 2

    Preheat your grill to medium-high heat (about 400°F to 450°F). Ensure the grill grates are meticulously clean to prevent the delicate fish skin from sticking.

  3. 3

    Prepare the gremolata: In a small bowl, combine the chopped parsley, lemon zest, minced garlic, chopped capers, 3 tablespoons of olive oil, and red pepper flakes. Stir well and set aside to let the flavors marry.

  4. 4

    Use paper towels to pat the fish fillets extremely dry on both sides. Moisture is the enemy of crispy skin.

  5. 5

    Brush both sides of the fillets generously with olive oil and season evenly with kosher salt and cracked black pepper.

  6. 6

    Once the grill is hot, dip a folded paper towel in a little oil and use tongs to rub it over the grates to create a non-stick surface.

  7. 7

    Place the fish fillets on the grill, skin-side down. Do not move them for at least 4-5 minutes; this allows the skin to crisp and naturally release from the grates.

  8. 8

    Place the lemon rounds on the grill alongside the fish. Grill the lemons for 2-3 minutes per side until charred and caramelized.

  9. 9

    Carefully flip the fish using a thin metal spatula. The skin should be golden and crispy. If it resists, give it another minute.

  10. 10

    Grill on the second side for another 2-4 minutes, depending on thickness. The fish is done when it is opaque throughout and flakes easily with a fork (internal temperature of 130°F-135°F for medium).

  11. 11

    Remove the fillets and charred lemon rounds from the grill and transfer them to a warm platter.

  12. 12

    Spoon the lemon-caper gremolata generously over the hot fish and serve immediately with the grilled lemon rounds for squeezing.

💡 Chef's Tips

Always pat the fish skin bone-dry before grilling to ensure maximum crispiness. If you are nervous about sticking, you can grill the fish on a bed of sliced lemons rather than directly on the grate. Arctic Char is leaner than salmon; be careful not to overcook it, as it can dry out quickly. Use a 'fish spatula'—a thin, flexible offset metal spatula—to get under the skin without tearing it. Substitute the parsley with dill or chives for a different but equally delicious herbal profile.

🍽️ Serving Suggestions

Pair with a chilled glass of crisp Sauvignon Blanc or an unoaked Chardonnay. Serve alongside grilled asparagus or snap peas tossed in lemon butter. A side of wild rice pilaf or roasted fingerling potatoes complements the buttery texture of the fish. Add a dollop of crème fraîche on the side for an extra touch of luxury. A light arugula salad with a simple vinaigrette provides a peppery contrast to the rich char.
