Swordfish Recipe: A Foolproof Guide to Cooking Perfect Swordfish Every Time

Spread the love

 When I was a kid, swordfish night was a big deal at our house. My dad, armed with a pair of oversized tongs and a lot of misplaced confidence, would grill swordfish steaks out back—and half the time, they turned out dry as toast. It wasn’t until culinary school that I realized swordfish doesn’t have to be a dry tragedy. Done right, it’s juicy, meaty, and downright glorious. Let’s make sure your swordfish turns out the way it should.

The Ultimate Swordfish Recipe: Step-by-Step Guide

Ingredients You’ll Need for the Perfect Swordfish

  • Swordfish steaks (1 to 1.5 inches thick)
  • Olive oil
  • Fresh lemon juice
  • Garlic cloves
  • Fresh herbs (thyme, oregano)
  • Kosher salt and black pepper

How to Prepare Swordfish for Cooking

Patting the Steaks Dry (This is Key)

First things first: grab a stack of paper towels and pat those swordfish steaks bone dry. Seriously, any moisture left on the surface is going to steam the fish instead of searing it.
Dry surface = better browning. You want that Maillard reaction (the tasty golden crust) happening, not a soggy mess.

Seasoning Swordfish the Right Way

  • Season right before cooking to keep the salt from pulling out too much moisture.
  • Use kosher salt and freshly ground black pepper generously. Swordfish is meaty—it can handle seasoning.
  • A light rub of olive oil helps prevent sticking, especially if you’re grilling.

Optional Boost:
Toss in a sprinkle of garlic powder or some finely chopped fresh herbs (like thyme or oregano) if you want an extra layer of flavor.

Cooking Techniques: Grilling vs Pan-Searing Swordfish

Grilling Swordfish: Bold Flavor and Beautiful Marks

  1. Preheat your grill to medium-high—you want it hot enough to sear but not so hot that it scorches (around 400°F).
  2. Oil the grates generously using a folded paper towel dipped in vegetable oil. Use tongs to rub it across the bars.
  3. Place the swordfish on the grill at an angle to get those pro-looking grill marks.
  4. Grill for about 3–4 minutes per side. You’re aiming for good sear marks and a slight springiness when you press the fish.
  5. Only flip once—fish is delicate, and too much flipping will tear it apart.

Sensory cue:
When the fish releases easily from the grill, it’s ready to flip. If it sticks, it’s not ready—give it another 30 seconds.

Pan-Searing Swordfish: Golden Crust and Juicy Center

  1. Choose a heavy-bottomed pan (cast iron or stainless steel is perfect) and get it screaming hot. The oil should shimmer—not smoke—before the fish goes in.
  2. Add a thin film of high-heat oil (like grapeseed or avocado oil).
  3. Place the swordfish steaks gently into the pan, laying them away from you to avoid splashes
  4. Sear without touching for 3–4 minutes, until you see a nice golden crust form.
  5. Flip carefully using a fish spatula and sear the other side.
  6. Optional chef move: During the last 30 seconds, throw in a knob of butter and a squeeze of lemon juice. Tilt the pan and spoon the melted butter over the steaks for extra flavor (this is called basting and it’s magic)

Sensory cue:
You’ll hear a steady, gentle sizzle—not a raging splatter or dead silence. That means you’ve got the heat just right.

Chef Tip Box:

“Don’t overcrowd your pan—it’ll steam, not sear. Give those steaks some breathing room, just like people at a party. Crowded pan = sad, gray swordfish. You want bold, proud golden crusts.”

Sensory Cues: How to Know When Your Swordfish is Done

Internal Temperature for Swordfish: Trust Your Thermometer

  • Target 130°F to 135°F in the thickest part of the steak for perfectly juicy swordfish.
  • Pull it off the heat at around 130°F because it will carryover cook (the internal temp rises 3–5 degrees after you take it off).
  • Anything beyond 140°F, and you’re heading into dry, tough territory.

Pro Tip:
Use an instant-read thermometer and insert it sideways into the thickest part—not straight down. Sideways gives you a better center reading without hitting the pan or grill surface

Resting Swordfish: Don’t Skip This

  • Rest it for at least 5 minutes after cooking.
  • Resting lets the juices redistribute instead of running out onto the plate the moment you cut into it.
  • Cover loosely with foil if your kitchen’s chilly, but don’t wrap it tightly—you don’t want it steaming itself.

Chef Insight:
If you slice swordfish right away, all that precious moisture you worked so hard to lock in? It spills out. Let it chill a minute. You’ll taste the difference.

Visual and Textural Clues: Read the Signs

Color Cues:

  • Swordfish turns from translucent to opaque white or very pale pink when done.
  • If it’s still glassy and see-through in the center, it needs another minute.
  • If it’s dry-looking, flaky like canned tuna, it’s overcooked.

Texture Cues:

  • Gently press the center with your fingertip or the back of a spoon.
  • It should feel springy and slightly firm—like a rare steak with a little bounce back.
  • If it’s super firm and stiff, you’ve overcooked it.

Pro Tip for Pan-Seared Swordfish:
When you tilt the steak, a little juice should bead up along the sides—that’s a good sign it’s juicy inside.
No juice? Probably cooked too long.

Simple is best: olive oil, lemon, garlic, salt, pepper, and a few fresh herbs.
