Grilled Halibut Fillets with Lemon & Butter Sauce

In this recipe, we’re keeping things simple and letting the quality of the fish do the work, pairing thick-cut halibut with a luxurious, silky butter sauce that brings everything together.

This dish is all about balance: a quick, high-heat sear for a lightly crisp exterior, followed by a gentle finish in the grill to keep the fish tender and moist.

This recipe is from our friends at Traeger Grills.

Serves 4.

INGREDIENTS

• 4 thick-cut halibut fillets (We recommend our Wild Halibut Dinner Fillets)
• 1/4 cup olive oil
• Salt & pepper to taste

For the Butter Sauce:

• 1 cup white wine
• 1 tbsp white wine vinegar
• 2 tbsp heavy cream
• 1/2 cup water
• 1/2 tsp freshly ground white pepper
• 1/4 cup shallots, chopped finely
• 1/2 tsp salt
• 2 sticks sweet cream butter, unsalted
• Juice of 1/2 a lemon

INSTRUCTIONS

1. To make the sauce, place wine, water, shallots, vinegar, salt and pepper in a sauce pan over medium to high heat. Bring to a boil to reduce it about 1/3 cup. Transfer to a food processor bowl to puree. Once pureed, transfer back to the sauce pan and add the cream.
2. Turn the heat to low, and add butter little by little, slowly whisking with a wire whisk after each addition (this should take about 3 to 4 minutes to add all the butter). Beat steadily, the sauce should never boil. Add lemon juice and season with salt and pepper to taste. Keep warm until ready to serve.
3. When ready to cook, preheat your grill to 375 degrees. Add olive oil to a Dutch oven and place inside the grill to preheat. Season halibut with salt and pepper and place inside the Dutch oven. Cook approximately 3 to 4 minutes per side, until internal temperature reaches 130 degrees F and fish is opaque and flakes easily with a fork.
4. Serve halibut with butter sauce. Enjoy.

This halibut with butter sauce is a great reminder that simple preparation and high-quality ingredients go a long way. Serve it right off the grill with a squeeze of lemon and your favorite sides for a complete, restaurant-worthy meal at home.
