Pan-Seared Arctic Char with Garlic Herb Butter and Crispy Skin Tips, FAQ & printable recipe

Tips for success

Keep the skin dry and the pan hot. The two conditions that matter most for crisp skin are moisture and heat: dry the fillets thoroughly, score them lightly, and let the oil shimmer before the fish goes in. A cast iron skillet holds heat well, so the surface stays steady even when the cold fish drops in. Press the fillets flat for the first ten seconds so the whole skin contacts the iron. This simple step prevents curling and gives you an even, golden crust from edge to edge.

Baste with purpose rather than fussing with the fish. Spooning the foaming butter over the flesh cooks the top evenly and builds flavor, but overhandling breaks the crust. Once the skin has set, tilt the pan so the butter pools at one side and scoop it over the fillets repeatedly.

Add the minced garlic and herbs with the second batch of butter so they toast gently. Watch the color closely and remove the pan from the heat if the butter darkens, since bitter butter is hard to rescue.

Variations

• Lemon and Dill: Add a few strips of lemon zest to the garlic herb butter and swap the parsley for chopped fresh dill. Finish each plate with a squeeze of lemon juice for a brighter, fresher finish.
• Salmon Version: Use skin-on salmon fillets in place of arctic char and sear them exactly the same way. The richer fish works well with the same garlic herb butter and blistered tomatoes.
• Trout Fillets: Choose skin-on trout fillets, which cook very quickly, and reduce the sear on the skin side to about three minutes. Keep the basting and tomato steps the same for a lighter fish with the same crisp skin.
• Extra Garlic: Increase the minced garlic to six cloves and add a pinch of red pepper flakes to the butter. The extra heat and aroma suit people who enjoy a bolder, more assertive flavor on their fish.

Storage and make-ahead

Fridge

Refrigerate cooked arctic char in a covered container for up to two days, and keep the butter and tomatoes separate.

Reheat

Reheat gently in a skillet over medium-low heat with a little butter, skin side down, just until warmed through to 145°F (63°C).

Arctic char is best eaten the same day it is cooked, while the skin is still crisp and the flesh is at its most tender. If you have leftovers, let the fish cool for no more than 2 hours at room temperature, then transfer it to a covered container and refrigerate it.

Store the blistered tomatoes and the garlic herb butter separately if you have any left, since the tomatoes soften and the butter firms once cold. Keep the fish in the refrigerator for up to two days. Do not leave cooked fish out on the counter for longer than the two-hour window, because bacteria multiply quickly at room temperature.

Some parts of this dish can be prepared in advance, which makes the actual cooking quick. Finely mince the garlic and chop the herbs up to a day ahead, then keep them covered in the refrigerator so they stay fresh and bright. Grate the hard cheese and store it in a sealed container in the refrigerator.

You can also measure the butter and leave it at a cool room temperature for up to two hours, or soften it for easier handling. Score and season the fish just before cooking rather than long before, because salt drawn in too early can make the flesh wet and make it harder to crisp the skin. Keep the raw fish refrigerated until you start cooking.

Serving ideas

Serve the fish straight from the skillet on warm plates, skin side up, so the crust stays crisp and dry. Spoon the garlic herb butter and blistered cherry tomatoes over the fillets while everything is still hot, then scatter the grated hard cheese across the top.

The contrast between the shatteringly crisp skin, the rich, flaky flesh and the juicy, sweet tomatoes is the heart of the dish. Pair it with something simple that will soak up the butter, such as crusty bread or a plain green salad dressed with lemon.

For a complete dinner, add a side that balances the richness of the butter without competing with it. Steamed green beans, roasted new potatoes or a bowl of lightly dressed greens all work well. Offer extra lemon wedges so each person can brighten their own plate, and keep a little extra butter warm for spooning over seconds. Eat the fish right away, while the skin is at its crispest, and enjoy the way the sweet tomatoes and fragrant garlic meet the fish on the plate.

Pan-Seared Arctic Char with Garlic Herb Butter and Crispy Skin

Prep 15 minCook 12 minTotal 27 minServes 2

Ingredients

• 1 lb arctic char fillets, skin on, scored diagonally
• kosher salt, to taste
• freshly ground black pepper, to taste
• 4 tbsp unsalted butter, divided
• 4 cloves garlic, finely minced
• 2 tbsp fresh herbs, such as parsley and chives, finely chopped
• hard cheese, finely grated, for serving
• 1 cup vine cherry tomatoes
• 1 tbsp neutral oil, such as canola

Instructions

1. Pat the arctic char fillets dry with paper towels. Score the skin diagonally with a sharp chef's knife, without cutting into the flesh. Season both sides with kosher salt and black pepper.
2. Finely mince the garlic cloves and chop the herbs. Set them aside together in a small bowl. Grate the hard cheese over a small plate for serving.
3. Heat the oil in the cast iron skillet over medium-high heat until shimmering. Add 2 tablespoons of butter and let it melt. Place the fillets skin side down and press lightly for 10 seconds so the skin stays flat.
4. Add the cherry tomatoes on the vine to the pan beside the fish. Spoon the foaming butter over the fillets as the skin crisps. Cook until the skin is golden and the tomatoes start to blister.
5. Flip the fillets with tongs. Add the remaining butter, the minced garlic and the chopped herbs to the pan. Spoon the foaming garlic herb butter over the flesh and cook until the fish is opaque and flaky at the thickest part.
6. Cook the fillets for another minute to crisp the skin fully. Transfer the fish skin side up to plates. Spoon the garlic herb butter and blistered tomatoes over the top, then finish with grated hard cheese.
