Crispy Skillet Arctic Char with Garlic Herb Butter

This crispy-skinned Arctic Char is the kind of dish that feels fancy but comes together in one skillet in under 20 minutes. The secret is a screaming-hot cast iron pan, a crosshatch-scored skin, and a foamy dill-garlic butter that bathes the fish and blistered cherry tomatoes in rich, nutty flavor.

A final shower of Parmigiano Reggiano adds a savory, salty crunch. Serve it straight from the pan for a weeknight dinner that impresses without the fuss.

Arctic Char is a beautiful fish with a delicate, salmon-like flavor and a skin that crisps up beautifully when seared properly. This recipe highlights that crispiness with a simple crosshatch scoring technique, then pairs it with a fragrant butter sauce made with fresh dill, garlic, and vine cherry tomatoes.

The result is a restaurant-quality dish that's ready in minutes. The key is to use a heavy cast iron skillet and to let the fish cook undisturbed until the skin is deeply golden and shatteringly crisp. The butter basting adds richness and helps the fish cook evenly, while the tomatoes burst and release their juices into the sauce.

Ingredients

Why this recipe works

Scoring the skin in a crosshatch pattern allows the fat to render out and the skin to crisp up evenly, creating a texture that's both delicate and crunchy.

The hot cast iron skillet provides intense, even heat that sears the skin instantly, locking in moisture and preventing sticking. The result is a perfect contrast between the crispy exterior and the tender, flaky interior.

Basting with cold butter, garlic, and dill creates a flavorful emulsion that coats the fish and tomatoes. The cold butter helps the sauce come together smoothly, while the garlic and dill infuse the butter with aromatic flavor.

The cherry tomatoes blister and soften, releasing their juices into the butter, creating a quick pan sauce that's both bright and rich.

Notes and substitutions

Choose Arctic Char fillets that are about 1 inch thick for even cooking. If you can't find Arctic Char, salmon or trout are excellent substitutes. For the best texture, look for fillets with the skin on and pat them very dry before searing – moisture is the enemy of crisp skin.

A cast iron skillet is ideal for this recipe because it retains heat well and creates a superior sear. If you don't have cast iron, use a heavy stainless steel or carbon steel pan. Use a fine grater for the Parmigiano Reggiano – the finer the grate, the more it melts and clings to the fish.

• Arctic Char: Salmon or trout fillets (skin-on) work well; adjust cooking time based on thickness.
• Aged Parmigiano Reggiano: Use a good-quality aged Parmesan or Grana Padano; avoid pre-grated versions for the best melt and flavor.
• Fresh dill: Fresh tarragon or chives can replace dill; reduce the amount if using tarragon, as it's stronger.
