Seared Halibut with Lemon-Caper Sauce

Seared halibut with lemon-caper sauce is a simple, elegant dish that brings Mediterranean flavors to your plate while supporting heart and brain health. Halibut is packed with omega-3 fatty acids, which help lower blood pressure, reduce triglycerides, and protect against heart attacks and strokes. It also provides key nutrients like selenium, magnesium, phosphorus, and B vitamins, all of which promote overall wellness. The bright, tangy lemon-caper sauce perfectly complements the tender, buttery fish, making this a delicious and nutritious meal for any occasion.

This easy but elegant one-skillet recipe abounds in zesty Mediterranean flavors and heart-healthy nuts. Halibut is rich in a wide range of micronutrients, including selenium, niacin, magnesium, phosphorus and vitamins B6 and 12, all of which help support brain, heart and blood vessel wellness. Oily fish, including halibut, are also an excellent source of omega-3 fatty acids, which help reduce blood pressure, triglycerides and risk for heart attack and stroke. If halibut isn’t available, use any mild-flavored white fish, such as pollock, cod, grouper, mahi mahi or haddock. The lemon-caper pan sauce is also delicious with chicken fillets or vegan fishless fillets. For a non-dairy sauce, replace the butter with vegan margarine, vegan ghee or another butter substitute, such as Earth Balance buttery spread.

Ingredients

1½ pounds of halibut fillets, skin removed and cut into eight pieces
Freshly ground pepper
1 tablespoon olive oil
3 tablespoons unsalted butter, divided 
1 small lemon, sliced
2 tablespoons of finely chopped shallots
1 teaspoon garlic, minced or crushed (optional)
¼ cup of capers, drained
3 tablespoons of fresh lemon juice
1 teaspoon of lemon zest, finely grated
2 tablespoons chopped flat-leaf parsley

Pat halibut fillets dry and season both sides with freshly ground pepper. Heat olive oil and two tablespoons of butter in a large nonstick skillet over medium-high heat until the butter starts to brown. Add halibut fillets to hot skillet and cook for 4-5 minutes, then turn and cook for 3-5 minutes more. Remove the halibut to a plate and add lemon slices to the skillet. Sear briefly on both sides, then remove lemon slices to the plate with the halibut. Reduce heat to medium and sauté shallots and garlic, if using, for one minute. Add capers, lemon juice and lemon zest, then cook for one additional minute. Turn off heat and add remaining tablespoon of butter to complete the pan sauce. Return halibut, lemon slices and any juices that are on the plate to the skillet and warm for one minute. Transfer fish and lemon slices to a serving platter and top with pan sauce. Garnish with chopped parsley — and enjoy! Serves four. Adapted from theartoffoodandwine.com and epicurious.com.

Capers and Halibut Recipe: Tips for Success

When preparing the dish, it’s important to pat the fish dry and season it lightly to ensure a golden sear. Cooking the halibut in a combination of olive oil and butter helps achieve a rich, nutty flavor while keeping the fish moist. After searing, the lemon slices, shallots, garlic, and capers in the pan transform into a luscious sauce that can be spooned directly over the fillets. Fresh parsley at the end adds a pop of color and herbal freshness.
