Pro Tip for Achieving the Perfect Sear on Swordfish

When preparing your swordfish steaks, ensure they are of even thickness for uniform cooking. If they are uneven, they may cook at different rates, resulting in some parts being overcooked while others are undercooked. Also, when cooking the couscous, remember to remove it from the heat and let it stand for 5 minutes. This allows the couscous to absorb the broth, making it fluffy and flavorful. Lastly, when making the tomato vinaigrette, be careful not to over blend the mixture. Leaving small chunks of tomato gives the vinaigrette a more appealing texture and a burst of fresh tomato flavor with each bite.

Essential Kitchen Tools for Making Swordfish with Vegetable Couscous

  • Blender: A kitchen appliance used to blend, puree, or emulsify food and other substances.
  • Large saucepan: A deep cooking vessel with a handle and often a lid, used for boiling, stewing, or making sauces.
  • Nonstick frying pan: A pan with a nonstick coating that prevents food from sticking, making it easier to cook with less oil or fat.
  • Fork: A utensil with prongs used for picking up and eating food.

Storage and Freezing Guidelines for Swordfish and Couscous

  • The swordfish can be stored in an airtight container in the refrigerator for up to 2 days. To freeze, wrap the cooked fish tightly in plastic wrap or aluminum foil and place in a freezer-safe container. It will keep in the freezer for up to 2 months. Thaw in the refrigerator before reheating.

  • The vegetable couscous can be stored in an airtight container in the refrigerator for up to 4 days. To freeze, transfer the cooled couscous to a freezer-safe container and freeze for up to 2 months. Thaw in the refrigerator and reheat in the microwave or on the stovetop with a little added water or chicken broth.

  • The tomato vinaigrette can be stored in a jar or airtight container in the refrigerator for up to 1 week. Give it a good shake or stir before using. I don't recommend freezing the vinaigrette, as the texture and flavor may change after thawing.

  • To reheat the entire dish, place the thawed swordfish and vegetable couscous in a baking dish, cover with foil, and bake at 350°F (175°C) for about 15-20 minutes, or until heated through. Drizzle the tomato vinaigrette over the top before serving.

  • If you have leftover swordfish, you can flake it and use it in salads, pasta dishes, or fish tacos for a quick and tasty meal.

How To Reheat Leftover Swordfish and Couscous

  • Preheat your oven to 350°F (175°C). Place the leftover swordfish on a baking sheet lined with parchment paper. Brush the fish with a little olive oil and sprinkle with some dried oregano, salt, and pepper. Bake for 8-10 minutes, or until the fish is heated through and slightly crispy on the edges. This method will help preserve the texture and flavor of the swordfish without drying it out.

  • For the vegetable couscous, place it in a microwave-safe bowl and add a tablespoon of water. Cover the bowl with a damp paper towel and microwave on high for 1-2 minutes, stirring halfway through. The steam from the water will help rehydrate the couscous and prevent it from becoming dry or clumpy. Fluff the couscous with a fork before serving.

  • To reheat the tomato vinaigrette, pour it into a small saucepan and heat it over low heat, stirring occasionally. Be careful not to let the vinaigrette boil, as this can cause the olive oil to separate and the flavors to become muted. If the vinaigrette seems too thick, you can add a splash of water or chicken broth to thin it out.

  • Alternatively, you can reheat the entire dish in a skillet. Heat a tablespoon of olive oil in a large skillet over medium heat. Add the leftover vegetable couscous and swordfish, stirring gently to combine. Cook for 5-7 minutes, or until everything is heated through. Drizzle the tomato vinaigrette over the top and serve immediately. This method allows the flavors to meld together and creates a slightly crispy texture on the couscous.

  • If you have an air fryer, you can use it to reheat the swordfish. Preheat the air fryer to 350°F (175°C). Place the swordfish in the air fryer basket and cook for 3-4 minutes, or until heated through and slightly crispy on the outside. This method is quick and helps maintain the texture of the fish. Reheat the vegetable couscous and tomato vinaigrette separately, as described above.
