How to Prepare
Start by patting the swordfish steaks dry with paper towels to ensure a beautiful golden sear. Season both sides with salt, black pepper, and fresh lemon zest, then let them rest for about five minutes so the flavours begin to absorb. Heat a large skillet over medium high heat and add the olive oil. Once the oil is shimmering, place the swordfish in the pan and cook for three to four minutes per side, depending on thickness, until the flesh turns opaque and flakes easily with a fork.
When the fish is nearly done, reduce the heat to medium and prepare the sauce in the same pan. Add the butter and minced garlic, letting it cook for about 30 seconds until fragrant. Stir in the fresh lemon juice to create a silky, tangy sauce. Return the swordfish to the pan and spoon the sauce generously over each steak. Finish with freshly chopped parsley, then serve immediately with your favorite sides for a fresh, restaurant quality seafood meal at home.
Pro Tips
For the best flavour and texture, always start with the freshest swordfish you can find. Fresh swordfish should have a firm texture, a mild ocean scent, and a slightly pinkish hue. If fresh isn’t available, opt for high quality frozen steaks and thaw them slowly in the refrigerator overnight. Before cooking, pat the fish completely dry to help achieve a perfect golden crust when searing.
When cooking, avoid moving the swordfish around in the pan let it sear undisturbed for a few minutes on each side so it develops beautiful colour and locks in moisture. Use fresh lemon juice instead of bottled for a brighter, more vibrant flavour, and add the garlic toward the end of cooking to prevent it from burning and turning bitter. Serve the swordfish right away for the juiciest results, as seafood tends to dry out quickly if left to sit.
Perfect Pairings and Toppings
This healthy lemon butter garlic swordfish pairs wonderfully with sides that complement its bright, zesty flavour. For a light and refreshing option, serve it alongside steamed asparagus, roasted Brussels sprouts, or a crisp garden salad. If you prefer something more filling, try herbed quinoa, garlic mashed potatoes, or a fluffy rice pilaf that will soak up the delicious lemon garlic sauce. Grilled vegetables like zucchini, bell peppers, or eggplant also add a smoky depth that enhances the dish.
When it comes to toppings, a sprinkle of freshly chopped parsley or dill adds color and freshness. Thin lemon slices or wedges make the plate look inviting while adding an extra burst of citrus. For a touch of briny contrast, scatter a few capers over the top, or if you like a bit of spice, finish with a light pinch of red pepper flakes. These small touches not only boost the flavor but also make the dish feel even more special.
