Swordfish is a versatile and flavorful seafood option that lends itself well to various cooking methods. When it comes to boiling fresh swordfish for steaks or kebabs, the process is quick and straightforward. Boil swordfish steaks for 8-10 minutes per inch of thickness, or until the internal temperature reaches 145°F (63°C).
For kebabs, the cooking time is slightly shorter due to the smaller pieces of fish. Cut the swordfish into 1-inch cubes and thread them onto skewers. Boil the kebabs for 5-7 minutes, turning them halfway through to ensure even cooking. The fish should be opaque and easily flake with a fork when done.
While boiling is a simple method for preparing swordfish, grilling is often preferred to enhance its natural flavors. Grilled swordfish steaks typically take 4-5 minutes per side over high heat, while kebabs require about 2-3 minutes per side. Regardless of the cooking method, swordfish’s firm texture and mild taste make it an excellent choice for a quick and satisfying seafood meal.
The Basics of Swordfish Preparation
Proper swordfish preparation is crucial for achieving delicious results. Selecting high-quality fish, following key preparation steps, and understanding doneness are essential for cooking perfect swordfish steaks and kebabs.
Selecting Quality Swordfish
Look for swordfish steaks with firm, moist flesh and a fresh ocean scent. The color should be pinkish-beige to white, without any brown spots. Avoid steaks with a strong fishy odor or dry, flaky texture.
Choose steaks that are 1 to 1.5 inches thick for even cooking. Thicker cuts work well for grilling, while thinner pieces are better suited for pan-searing or broiling.
Frozen swordfish can be a good option if fresh is unavailable. Ensure it’s properly vacuum-sealed and has been stored at a consistent temperature.
Preparation Steps Before Cooking
Thaw frozen swordfish in the refrigerator overnight. Pat dry with paper towels to remove excess moisture, which helps achieve a better sear.
Remove any dark, strongly flavored areas along the edges of the steak. These can impart a bitter taste to the fish.
Season swordfish simply with salt and pepper, or create a marinade using olive oil, lemon juice, and herbs. Marinate for no more than 30 minutes to prevent the fish from becoming mushy.
Brush the steaks lightly with oil before cooking to prevent sticking and promote even browning.
The Importance of Doneness
Swordfish cooks quickly due to its firm texture and relatively low fat content. Overcooking can result in dry, tough fish.
Aim for an internal temperature of 130°F (54°C) at the thickest part of the steak. The fish will continue cooking after removal from heat, reaching the FDA-recommended 145°F (63°C).
Cook swordfish until it’s just opaque throughout. The flesh should flake easily with a fork but still retain some moisture.
Swordfish is rich in omega-3 fatty acids, which can be lost through overcooking. Proper doneness preserves these beneficial nutrients and ensures optimal flavor and texture.
Boiling Swordfish: Techniques and Timing
Boiling swordfish offers a healthy cooking method that preserves moisture and flavor. Proper techniques and timing are crucial for achieving tender, flaky results.
How to Boil Swordfish Steaks
To boil swordfish steaks, start with a large pot of water. Add salt and any desired aromatics like lemon slices or herbs. Bring the water to a gentle simmer, not a rolling boil.
Carefully lower the swordfish steaks into the simmering water. Cook for 8-10 minutes per inch of thickness. For a 1-inch thick steak, this typically means 8-10 minutes total.
Use a slotted spoon to remove the steaks from the water. Test for doneness by checking if the flesh flakes easily with a fork. The internal temperature should reach 145°F (63°C).
How to Boil Swordfish for Kebabs
For swordfish kebabs, cut the fish into 1-inch cubes before boiling. This ensures even cooking and quicker preparation time.
Prepare the poaching liquid as you would for steaks. Gently lower the swordfish cubes into the simmering water. Cook for 5-7 minutes, stirring occasionally to ensure even heat distribution.
Remove the cubes with a slotted spoon when they turn opaque and flake easily. Drain well before threading onto skewers with vegetables or fruits.
Determining Optimal Boil Times
Boiling times for swordfish depend on the size and thickness of the pieces. Use this guide for reference:
- 1-inch thick steaks: 8-10 minutes
- 2-inch thick steaks: 16-20 minutes
- 1-inch cubes: 5-7 minutes
Always check for doneness before serving. The fish should be opaque throughout and flake easily. Avoid overcooking, as this can lead to dry, tough swordfish.
Test the internal temperature with a meat thermometer. The FDA recommends cooking fish to 145°F (63°C) for food safety. Remove the swordfish from heat when it reaches this temperature.
Seasoning and Marinades for Swordfish
Proper seasoning and marinades are key to enhancing swordfish’s mild flavor. The right combinations can elevate this firm-textured fish to new culinary heights.
Classic Seasoning Combinations
Salt and black pepper form the foundation of most swordfish seasonings. A simple blend of kosher salt, freshly ground black pepper, and lemon zest creates a bright, clean flavor profile. Garlic powder adds depth without overpowering the fish’s natural taste.
For a Mediterranean twist, combine dried oregano, basil, and thyme with salt and pepper. This herb mixture complements swordfish’s robust texture. A sprinkle of cayenne pepper introduces a subtle heat that pairs well with the fish’s mild flavor.
Fresh herbs like parsley, cilantro, or dill can be chopped and sprinkled over the fish just before serving. This adds a burst of color and freshness to the dish.
Marinade Recipes for Enhanced Flavor
A basic marinade of olive oil, lemon juice, and minced garlic infuses swordfish with classic flavors. For added complexity, incorporate Dijon mustard and a splash of white wine.
Try this zesty marinade:
- 1/4 cup extra virgin olive oil
- 2 tablespoons fresh lemon juice
- 1 tablespoon Dijon mustard

- 1 minced garlic clove
This marinade works well for both grilled steaks and kebabs.
Alternative Seasonings and Marinades
For a tangy kick, create a marinade with sherry vinegar, olive oil, and smoked paprika. This Spanish-influenced blend adds depth and a subtle smoky note to the fish.
A spicy marinade can be made by combining hot sauce, lime juice, and cilantro. This works particularly well for swordfish kebabs, adding a bold flavor that stands up to the grill.
Experiment with different citrus juices like orange or grapefruit for a sweeter profile. Pair these with fresh herbs like tarragon or chives for a unique flavor combination.
For a rich umami taste, try a miso-based marinade:
- 2 tablespoons white miso paste
- 1 tablespoon mirin
