It doesn’t get easier or more delicious than Pan-Seared Swordfish with Lemon Caper Sauce. The swordfish steaks cook quickly on a stovetop (about 4-5 minutes per side, based on thickness), and then as they rest you make a really simple pan sauce that’s bright, citrusy, and totally restaurant-worthy. It’s finished with lots of capers, which beautifully complement the fish.
Pan-searing is one of the best methods for cooking swordfish steaks, as it quickly sears the exterior, locking in the juices and creating a flavorful crust, while the interior remains moist and tender. Go ahead and make this for that person you’ve been longing to impress — it is foolproof!

What You’ll Need
- Swordfish steaks, seasoned with Kosher salt and black pepper. Each swordfish steak should be about 6oz each and ~1-inch thick.
- Neutral oil, for pan searing the fish. You want to use something with a high smoke point like grapeseed, avocado, or canola oil.
For the lemon caper sauce, you’ll need a finely chopped shallot, low-sodium chicken broth, a fresh lemon, capers, and unsalted butter.
Ingredient Substitutions
You can easily use another type of fish if you want — the lemon caper sauce would be delicious on salmon, pan seared scallops, branzino — really anything!
And feel free to add a splash of white wine to the sauce before you add chicken stock.
How To Make Pan Seared Swordfish Steaks
- Prepare the swordfish steaks by patting dry with a paper towel and seasoning generously on both sides with Kosher salt and black pepper.
- Sear the swordfish in a skillet preheated to medium-high with a little olive oil. Cook for 4-5 minutes per side, then remove the fish to a plate.
- Make the lemon caper sauce. In the same skillet, reduce the heat to medium, then add a chopped shallot. Season, stir, then cook for 1 minute. Add chicken broth, being sure to scrape the bottom of the pan. Add the juice of 1 lemon and 2 tablespoons of drained capers. Turn off the heat, then stir in 3 tablespoons of cold butter. Taste, adjust seasoning, then pour the sauce over the cooked swordfish steaks.
This is such a quick and easy fish dinner! Enjoy with chopped parsley or thinly sliced chives and fresh lemon wedges. Deeeee-lish!
FAQs
Can I use frozen swordfish?
Yes, frozen swordfish can be used. Thaw it in the refrigerator overnight before cooking, then pat dry with paper towels to help remove excess moisture (otherwise it won’t sear well).
Can I grill the swordfish instead of pan-searing?
Absolutely! Preheat the grill to medium-high heat and grill the swordfish for about 4-5 minutes per side.
How do you know when swordfish is ready to flip?
First, make sure the pan was really hot before you add oil. Once the oil has heated, add the seasoned swordfish steaks. Cook for 4-6 minutes (assuming a 1-inch thick steak — adjust time if thinner or thicker). The fish should easily release and lift away from the pan when you go to flip it over. If it doesn’t release easily, the pan may not have been hot enough.
Expert Tips
- Ensure the skillet is hot before adding the swordfish to achieve a beautiful sear. You’ll also need topat the swordfish steaks dry with a paper towel.
- Use a heavy-bottomed skillet that can retain heat, such as stainless steel or cast-iron.
- Don’t overcrowd the pan. Once you add the fish, don’t move the steaks around. When it’s time to flip them, they should life easily.
- Don’t overcook the swordfish; it should be opaque and just cooked through to maintain its juicy texture.
- Adjust the lemon juice quantity according to your taste preference for tanginess in the sauce.
Make-Ahead, Leftovers, & Storage
- To make-ahead: The lemon caper sauce can be made ahead and refrigerated for up to 3 days. Reheat gently on the stove before serving.
- Leftovers and storage: Cooked swordfish can be stored in an airtight container in the refrigerator for up to 2 days. Reheat swordfish steaks gently in a skillet over low hot to avoid overcooking.
- To freeze: It’s not recommended to freeze cooked swordfish with the sauce as it might compromise the texture.
How To Serve
Serve the swordfish steaks with lemon caper sauce alongside roasted vegetables or a light side salad. A few of my favorites are this Roasted Broccolini with Garlicky Breadcrumbs, Sicilian Cauliflower, and this easy 5-Minute Arugula Salad with Parmesan.
Pair it with a side of couscous, quinoa, or garlic mashed potatoes for a complete meal.
A real triumph of a dish for swordfish-lovers! Quick-to-make, flavorful, and easily pairs with a variety of side dishes. It’s so good.

Equipment
Large skillet about 10-12-inches
Fish spatula or tongs
Ingredients
- 4 (6-ounce) swordfish steaks, about 1½ lbs
- 1 tsp Kosher salt
- ¼ tsp freshly ground black pepper
- 3 Tbsp neutral oil
- 1 medium shallot, finely chopped
- ¾ cup low-sodium chicken broth
- 1 lemon, plus more cut into wedges for serving
- 2 Tbsp capers, drained
- 3 Tbsp unsalted butter, very cold
- Fresh parsley or thinly sliced chives, for serving
Instructions
Season the swordfish. Season swordfish steaks on both sides with 1 tsp Kosher salt and ¼ tsp freshly ground black pepper.
Cook the swordfish. Preheat a large skillet over medium-high heat for about 3 minutes. Add 2-3 Tbsp of neutral oil (enough to coat the bottom of the pan). When the oil shimmers, carefully add the seasoned swordfish steaks then cook, undisturbed, for 4-6 minutes per side. Use tongs or a fish spatula to carefully transfer each swordfish steak to a large serving platter.
Make the pan sauce. Reduce the heat to medium, then add 1 finely chopped shallot. Season lightly with a pinch of Kosher salt, then cook, stirring occasionally, for 1 minute. Increase the heat to medium-high, then add ¾ cup low-sodium chicken broth, then use a spatula to scrape up any browned bits. Allow the sauce to reduce for 2-3 minutes.
Finish with butter, then serve. Add the juice of 1 lemon and 2 Tbsp drained capers, then stir well. Remove from the heat, then stir in 3 Tbsp cold butter. Taste, adjust seasoning with Kosher salt and black pepper as desired, then pour over the swordfish. Garnish with chopped parsley or chives, then serve immediately with lemon wedges on the side.
