Grill Prep

  1. 1

    Preheat and Clean

    Clean your grill grates thoroughly and preheat to medium-high heat (approx 200 C).

    Tip: A clean, well-oiled grate is essential to prevent the delicate skin from sticking.

How to Make Grilled Arctic Char With Lemon Caper Butter

Total time: 20 min · Yields 4 servings

  1. 1

    Season the Fish

    Pat the arctic char fillets completely dry with paper towels. Brush both sides with olive oil and season the flesh side generously with salt and pepper.

  2. 2

    Sear Skin Side Down

    Place fillets on the grill skin-side down. Close the lid and cook for 5 to 6 minutes without moving them. This allows the skin to crisp and release naturally from the grates.

  3. 3

    The Flip

    Carefully flip the fillets using a thin metal spatula. Cook for another 2 to 3 minutes until the internal temperature reaches 52 C for medium doneness.

  4. 4

    Brown the Butter

    While the fish rests, melt butter in a small saucepan over medium heat until it begins to foam and turn golden brown. Stir in the capers, lemon juice, and zest.

  5. 5

    Final Emulsion

    Remove the butter from heat and stir in the parsley. The residual heat will soften the capers and release their brine into the butter sauce.

Chef's Tips

  • Do not overcook arctic char; because it is leaner than salmon, it can dry out if it exceeds 55 C.
  • Always place fish on the grill at a 45 degree angle to the grates to get professional looking sear marks.
  • If the skin sticks, wait 30 seconds. Fish typically releases itself once the skin is sufficiently crisped.

What to Serve with Grilled Arctic Char With Lemon Caper Butter

The garlic butter sauce is the star — pick sides that soak it up or balance the richness.

  • Serve over a bed of fluffy quinoa
  • Pair with a crisp arugula salad
  • Garnish with extra lemon wedges

Recipe Variations

Once you've mastered the base recipe, try these popular twists.

Variation

Swap capers for chopped green olives for a different briny profile.

Variation

Add a pinch of smoked paprika to the oil rub for a deeper color and smoky finish.

Variation

Use lime juice and cilantro instead of lemon and parsley for a bright citrus twist.

Storage & Reheating

Leftover char can be refrigerated in an airtight container for up to 2 days. Reheat gently in a pan over low heat to avoid toughening the proteins.

Frequently asked questions

What does grilled arctic char taste like?

It has a flavor profile that is a cross between salmon and trout. It is milder and less oily than salmon, but richer and more buttery than trout.

Should I leave the skin on for grilled arctic char?

Yes, leaving the skin on protects the delicate flesh from the high heat of the grill and provides a delicious crispy texture.

How do I know when the fish is done?

The fish is done when the flesh is opaque and flakes easily with a fork, or when it reaches an internal temperature of 52 to 54 degrees Celsius.

Is arctic char a sustainable seafood choice?

Yes, most arctic char available is responsibly farmed in closed tank systems, making it a highly sustainable alternative to some salmon varieties.

Can I make this arctic char recipe in a pan?

Absolutely. Use a cast iron skillet over medium-high heat with a little oil, following the same timing for skin-side and flesh-side cooking.
