Ingredients To Make Sicilian Swordfish At Home
- Swordfish steaks, about 1 ½ lbs total.
- Kosher salt and freshly ground black pepper: to season the fish!
- Neutral oil for cooking
To make the olive relish, you’ll need:
- Castelvetrano olives and Kalamata olives, pitted and thinly sliced or roughly chopped (your preference!).
- A large tomato — we always reach for heirloom varieties, as we love their intense tomato flavor.
- Drained capers, which add additional brininess that works so well with the remaining relish ingredients.
- Toasted pine nuts, for some added nuttiness and crunch.
- Golden raisins, for sweetness.
- Fresh parsley, finely chopped.
The “dressing” is made from extra virgin olive oil, red wine vinegar, and a squeeze of fresh lemon juice.
Make The Sweet And Salty Olive Relish
It’s so simple, you just need 5 minutes to pull this olive relish together! Simply combine everything in a mixing bowl, then drizzle on the olive oil and red wine vinegar. Give it a good toss, sprinkle with a pinch of Kosher salt, as needed, then taste and adjust seasoning.
Note that olives and capers are plenty salty on their own. The salt is really to help season the tomatoes. You can season these before adding to the bowl, if easier!
If you’re using older raisins that are dried out and tough, simply rehydrate them by placing in a small bowl, then covering with a bit of room temperature water. Let sit for 10 minutes, then drain. They’ll be juicy and plump yet again!
How Far In Advance Can You Make The Olive Relish?
This will keep for up to 3 days in a fridge, however, the tomatoes will be best on the first day. You can always combine everything else ahead of time, then stir in the chopped tomatoes just before serving.
How To Cook Swordfish Steaks
- Make sure to season the swordfish steaks really well with Kosher salt and freshly ground black pepper on both sides.
- Next, heat Hestan’s Thomas Keller Insignia Sauté Pan over medium-high heat for a few minutes. When it’s hot, add a couple tablespoons of a neutral oil, such as grapeseed, canola, avocado, or vegetable oil. You want just enough to lightly coat the bottom of the pan.
- Carefully add the seasoned swordfish steaks to the hot pan, the cook, undisturbed, for 5-6 minutes per side. Once finished, squeeze half a lemon on top, right over the cooked fish.
- Spoon the olive relish on top, then serve immediately with additional lemon wedges and chopped parsley for garnish. We love to sprinkle with a tiny pinch of flaky sea salt, as well.
It’s juicy, tender, and so unbelievably full of flavor!
Do you remove the swordfish skin? No, we leave it on as the fish cooks. While swordfish skin is thick and rubbery, it’s easier to remove afterwards. The skin simply peels away from the flesh of the swordfish. You can then discard and throw away.
Tips For Cooking With Stainless Steel
I have been cooking with Hestan Culinary’s Thomas Keller Insignia line for months now, and this sauté pan is seriously a work horse. If I can convince you to purchase one new pan to take your at-home cooking to the next level, it’s got to be this high quality, stainless steel 11-inch sauté pan. If you want to make sure your proteins are cooked perfectly, this is the way to go!
Some of our best tips for cooking with stainless steel (which, by the way, is the most commonly used cookware in professional kitchens!):
- The pan must be preheated before you add any food to the pan!
- You need to use an appropriate amount of oil, enough to coat the entirety of the bottom of the pan. You’ll know the oil is hot enough when it begins to shimmer.
- It is helpful to bring proteins to room temperature before adding them to the pan.
- Be patient! A proper sear takes time. The protein should move freely in the pan when shaken lightly. That’s when you know it’s ready to flip, when it releases easily, without any hesitation.
- Browned bits at the bottom? That’s a pro, not a con! Stainless steel is the best choice for cooking when making a pan sauce! Plus, it will result in a clean pan afterwards. How to best make a pan sauce? Once the protein has fully cooked, deglaze the pan with white wine or lemon juice to help release the browned bits.
Follow these steps with Hestan Culinary’s Thomas Keller Insignia sauté pan and see the difference for yourself!
What To Serve With Sicilian Swordfish
Now that you’ve mastered cooking pan seared swordfish, what do you serve it with?
We love a simple couscous salad (the lemon flavor matches the acidity in this recipe, so they’re a perfect pairing!).
For easy side dishes, consider serving with: white rice, creamy polenta, or Sicilian cauliflower. But the easiest side dish of all is our arugula salad. It’s the perfect, gluten-free base for this swordfish to rest upon!
