Step-by-Step Instructions
Preparing the Marinade
To start, grab a small bowl. In it, mix together these ingredients:
- 4 tablespoons olive oil
- 4 cloves garlic, minced
- Zest and juice of 2 large lemons
- 1 tablespoon fresh thyme leaves (or 1 teaspoon dried thyme)
- Salt and pepper to taste
Whisk until everything blends well. This mix will be your marinade. The olive oil adds richness, while lemon and garlic bring a bright taste.
Marinating the Swordfish
Next, take your swordfish steaks. You need four steaks, each about 6 ounces. Place them in a shallow dish or a resealable plastic bag. Pour the marinade over the fish. Make sure the steaks are well coated.
Let them marinate in the fridge for at least 30 minutes. If you have more time, leave them for up to 2 hours. The longer they sit, the more flavor they absorb.
Grilling Process
Now, let’s get to grilling. Preheat your grill to medium-high heat. Before placing the fish on the grill, lightly oil the grates. This helps prevent sticking.
Remove the swordfish from the marinade. Let any excess marinade drip off. Place the fish on the grill and cook for 4-5 minutes per side. You want the fish to become opaque and flake easily with a fork. Be careful not to overcook it, or it may become dry.
Once done, remove the swordfish from the grill. Let it rest for a couple of minutes. This helps keep it juicy. Serve with lemon wedges and garnish with fresh parsley. Enjoy!
Tips & Tricks
Selecting Fresh Swordfish
When choosing swordfish, look for bright, moist flesh. It should have a clean scent, not fishy. The color should be pinkish or light beige. Also, check for firm texture. Press it lightly; it should spring back. Fresh fish will have clear eyes and shiny skin.
Preventing Sticking on the Grill
Oiling the grill grates can stop the swordfish from sticking. Use a paper towel soaked in oil. Hold it with tongs and rub it on the grates. Do this right before you place the fish on the grill. This step helps keep your fish intact and looking great.
Avoiding Overcooked Fish
Swordfish is perfectly cooked when it is opaque. It should flake easily with a fork. Check the thickest part of the fish for doneness. If it is still translucent, give it a bit more time. Aim for 4-5 minutes on each side for the best results.
Pro Tips
- Marinate for Longer: Letting the swordfish marinate for up to 2 hours will enhance the flavor and tenderness of the fish.
- Check Grill Temperature: Ensure your grill is preheated to medium-high heat to achieve perfect grill marks and prevent sticking.
- Use Fresh Ingredients: Opt for fresh lemons and herbs to elevate the dish's flavor profile significantly.
- Rest Before Serving: Allow the grilled swordfish to rest for a few minutes after cooking to retain its moisture and flavor.
Variations
Ingredient Substitutions
If you can't find swordfish, you can try other fish. Tuna, mahi-mahi, or salmon work well. These fish have a similar texture and taste. For the marinade, you can swap olive oil for avocado oil. This change adds a different flavor but keeps it light and healthy. You can also use lime juice instead of lemon for a unique twist.
Side Dish Pairings
Pair your grilled swordfish with some healthy sides. Steamed broccoli or asparagus brings color and nutrition. A fresh salad with mixed greens, cherry tomatoes, and cucumber adds crunch. Quinoa or brown rice can serve as a filling base. They both soak up the flavorful juices from the fish. Don't forget some lemon wedges to brighten up your plate!
Kid-Friendly Modifications
To make this dish more appealing to kids, cut the swordfish into smaller pieces. Kids love finger foods! You can also serve it with a fun dipping sauce. A simple yogurt sauce with herbs can be a hit. If they prefer milder flavors, reduce the garlic or use a little honey in the marinade. This way, they can enjoy a healthy meal without fuss.
Storage Info
Storing Leftovers
To keep your lemon-garlic grilled swordfish fresh, store it right. First, let it cool to room temperature. Then, wrap each piece in plastic wrap or foil. Place the wrapped fish in an airtight container. You can keep it in the fridge for up to three days. For longer storage, freeze the swordfish. Use freezer-safe bags or containers. Properly stored, it can last up to three months in the freezer. Just remember, the sooner you eat it, the better it tastes!
Reheating Instructions
When you’re ready to enjoy your leftovers, reheating is key. You can use a few methods to keep the flavor. The best way is to reheat it in the oven. Preheat the oven to 350°F (175°C). Place the swordfish on a baking sheet. Cover it with foil to keep it moist. Heat for about 10-15 minutes or until warmed through. You can also use a microwave. Place the fish on a microwave-safe plate with a damp paper towel on top. Heat in short bursts, checking often to avoid overcooking. Enjoy your delicious swordfish just as you did the first time!

How can I tell if swordfish is cooked?
To check if swordfish is cooked, look for a few signs:

Yes, you can use other fish! Here are some great substitutes:
