Charred Norwegian Cod with Lemon Thyme Butter

There is a distinct elegance to fresh Norwegian cod, known for its pristine white flesh and mild, sweet flavor. However, elevating this delicate fish from good to unforgettable requires the right technique: the perfect char. Using the Arteflame grill allows you to achieve a restaurant-quality sear that locks in moisture while creating a beautifully caramelized crust. This recipe focuses on simplicity, letting the quality of the ingredients shine through. The combination of smoky char, rich butter, and the brightness of fresh lemon and thyme creates a harmony of flavors that feels both sophisticated and comforting.

Cooking fish on a grill can often be intimidating due to fears of sticking or falling apart. The solid steel cooktop of the Arteflame eliminates these worries, providing an even, high-heat surface that sears the fish gently yet effectively. Whether you are hosting a summer dinner party or looking for a healthy, high-protein weeknight meal, this charred cod recipe delivers exceptional taste with minimal effort. Prepare to impress your guests with a dish that looks as incredible as it tastes.

Ingredients

• 4 fresh Norwegian Cod fillets (approx. 6 oz each, skin-on or skinless)
• 4 tablespoons unsalted butter, melted
• 2 tablespoons olive oil (plus extra for the grill)
• 1 fresh lemon (zested and juiced)
• 4 sprigs of fresh thyme, leaves stripped and chopped
• 2 cloves garlic, minced
• Sea salt and freshly cracked black pepper to taste
• Fresh parsley for garnish (optional)

Instructions

Step 1: Prepare the Arteflame Grill

1. Start by building a fire in the center of your Arteflame grill. Allow the fire to burn down until the center grate is extremely hot and the outer flat steel cooktop reaches a medium-high searing temperature (approx. 400°F - 450°F).
2. Scrape the cooktop clean and apply a thin layer of olive oil to season the surface where you plan to cook the fish. This ensures a non-stick surface and a perfect sear.

Step 2: Season the Cod

1. Pat the cod fillets completely dry with paper towels. Removing excess moisture is crucial for getting a good char rather than steaming the fish.
2. Brush both sides of the fillets with olive oil. Generously season with sea salt and cracked black pepper.

Step 3: Prepare the Lemon Thyme Butter

1. Place a small cast-iron sauce pot or heat-safe skillet on a cooler section of the flat cooktop.
2. Add the butter, minced garlic, lemon juice, lemon zest, and chopped fresh thyme.
3. Let the mixture melt and simmer gently for 2-3 minutes until fragrant. Move the pot to the outer edge of the grill to keep warm without burning the garlic.

Step 4: Sear the Fish

1. Place the cod fillets onto the hot, oiled steel cooktop. If using skin-on fillets, place them skin-side down first.
2. Allow the fish to cook undisturbed for 3-4 minutes. Do not try to move it too early; the fish will naturally release from the steel once a crust has formed.
3. Carefully flip the fillets using a thin metal spatula. Cook for another 2-3 minutes on the other side until the flesh is opaque and flakes easily with a fork.

Step 5: Finish and Serve

1. Just before removing the fish from the grill, spoon a generous amount of the warm lemon thyme butter over the fillets, allowing it to sizzle on the hot iron and infuse the fish.
2. Transfer the cod to a serving platter. Drizzle with any remaining butter sauce and garnish with fresh parsley and a wedge of lemon.

Tips

Achieving the perfect piece of grilled fish is all about temperature control and patience. One of the most common mistakes is moving the fish before the Maillard reaction has occurred. If you try to lift the fillet and it feels stuck, it simply isn't ready to flip yet—give it another thirty seconds. On the Arteflame, utilize the heat zones intelligently; start the sear closer to the center where the heat is higher, and if the fish is thick, move it toward the outer edge to finish cooking the center without burning the exterior.

Additionally, always ensure your cod is room temperature before it hits the grill. Taking the fish out of the refrigerator 15 to 20 minutes prior to cooking allows for more even cooking throughout the fillet. If you are using skin-on cod, score the skin lightly with a sharp knife to prevent it from curling up as it hits the hot steel, ensuring the skin gets crispy rather than chewy.

Variations

While lemon and thyme is a classic pairing, the mild flavor of Norwegian cod makes it an excellent canvas for various flavor profiles. You can easily adapt this recipe to suit your mood or the theme of your meal. Here are a few delicious ways to switch things up without changing the core technique:

• Mediterranean Style: Add chopped Kalamata olives, capers, and halved cherry tomatoes to the butter sauce for a briny, savory finish.
• Cajun Blackened: Swap the salt and pepper for a robust Cajun spice rub and finish with lime juice instead of lemon for a spicy kick.
• Asian Fusion: Replace the lemon thyme butter with a glaze made from soy sauce, fresh grated ginger, sesame oil, and scallions.
• Garlic & Herb: Omit the lemon and double the garlic, adding chopped rosemary and dill alongside the thyme for an earthy, aromatic profile.
• Spicy Citrus: Add red pepper flakes or a dash of chili oil to the lemon butter for a heat that cuts through the richness of the fish.

Best pairings

A beautifully charred cod fillet deserves sides that complement its delicate texture without overpowering it. Since you already have the Arteflame fired up, it makes sense to utilize the cooktop for your side dishes as well. Vegetable sides that benefit from a high-heat sear are ideal companions for this dish. The brightness of the lemon sauce pairs wonderfully with green vegetables and starchy sides alike.

Consider serving this dish with grilled asparagus spears seasoned with nothing more than olive oil and salt; they cook quickly alongside the fish. For a heartier meal, smashed baby potatoes crisped up on the flat top are a crowd favorite. If you prefer a lighter option, a fresh arugula salad with a vinaigrette dressing provides a peppery contrast to the buttery fish. For wine, a crisp Sauvignon Blanc or an unoaked Chardonnay will cut through the butter and highlight the citrus notes perfectly.

Conclusion

This Charred Norwegian Cod recipe exemplifies the beauty of cooking on an Arteflame grill—simple ingredients transformed by fire into something extraordinary. The combination of the crispy, golden-brown exterior and the tender, flaky interior provides a textural experience that is difficult to replicate with traditional pans.
