Swordfish is a popular seafood choice, known for its firm texture and rich flavor. However, many home cooks and even experienced chefs often encounter the frustrating issue of rubbery swordfish. This problem usually stems from improper cooking techniques, leading to a tough and chewy texture that diminishes the overall dining experience. In this article, we’ll explore why swordfish can become rubbery and how to ensure you cook it perfectly every time.
The Science Behind Rubbery Swordfish
Swordfish is a dense, meaty fish, and its texture is heavily influenced by how it’s cooked. The protein fibers in swordfish, like in other fish, contract when exposed to heat. If these fibers contract too much—due to high heat or overcooking—the result is a rubbery, dry piece of fish. The key to avoiding this lies in understanding how to apply the right amount of heat during cooking.
Proper Fish Cooking Techniques emphasize the importance of controlling cooking temperatures and times. Using high heat can be tempting for a quick meal, but it often leads to the undesirable rubbery texture. Instead, moderate heat allows the fish to cook evenly without toughening the meat.
Another common issue is using the wrong cooking method. Cooking Swordfish explains that certain methods, like grilling or broiling, can easily cause the fish to overcook if not carefully monitored. These methods require precise timing and temperature control to maintain the swordfish’s delicate texture.

Common Cooking Mistakes That Make Swordfish Rubbery
Avoiding rubbery swordfish starts with recognizing the most common cooking mistakes:
- Overcooking Swordfish: Overcooking is the primary cause of a rubbery texture. Swordfish should be cooked until just opaque in the center. Use a meat thermometer to check that the internal temperature reaches 130°F (54°C) and then remove it from the heat.
- Using the Wrong Cooking Methods: Grilling, broiling, or searing at too high a temperature can lead to a rubbery texture. Instead, consider baking or poaching, which allow for more gentle cooking.
- Improper Preparation: Not properly preparing the swordfish before cooking can also result in a tough texture. Thaw swordfish steaks in the refrigerator and consider brining them in a saltwater solution for 30 minutes before cooking. This helps to keep the meat moist and tender.

Signs Your Swordfish Is Overcooked
Knowing when your swordfish is done can be tricky, but there are clear signs to watch for:
- The flesh becomes overly firm and loses its translucency.
- It has a dry, flaky texture that is hard to cut through.
- The color turns from pinkish to a dull white.
How to Cook Swordfish Perfectly
To avoid the dreaded rubbery texture, follow these best practices:
Best Cooking Methods
- Grilling: Use medium heat and grill for about 3-5 minutes per side. The swordfish should be just opaque in the center.
- Broiling: Broil the swordfish about 5 inches from the heat source for 4-5 minutes per side.
- Baking: Bake at 400°F (200°C) for 12-15 minutes, or until the fish reaches an internal temperature of 130°F (54°C).
- Searing: Sear in a hot pan with a little oil for 3-4 minutes per side, then finish in the oven if necessary.
Temperature Control
Using a meat thermometer is the best way to ensure your swordfish is cooked to perfection. The ideal internal temperature is 130°F (54°C), at which point the fish will be cooked through but still moist and tender.
Resting Swordfish
After cooking, let the swordfish rest for 5 minutes. This allows the juices to redistribute, ensuring a moist and tender texture.

Marinades and Seasoning for Swordfish
- Marinades: Use marinades that contain acid, like lemon juice or vinegar, to tenderize the swordfish and add flavor.
- Seasoning: Simple seasoning with salt, pepper, and fresh herbs complements the rich flavor of swordfish without overpowering it.
Alternative Cooking Techniques to Avoid Rubbery Swordfish
- Sous-Vide Cooking: This method involves vacuum-sealing the swordfish and cooking it in a water bath at a precise temperature, usually around 130°F (54°C). The result is perfectly tender swordfish every time.
- Poaching Swordfish: Poaching in a flavorful broth or white wine is a gentle method that prevents overcooking and helps maintain the fish’s delicate texture.
Frequently Asked Questions
- Why is my swordfish always rubbery?
- This is usually due to overcooking or using high heat methods like grilling without proper temperature control.
- Can I fix rubbery swordfish after it’s cooked?
- Unfortunately, once swordfish becomes rubbery, it’s difficult to reverse the texture. However, serving it with a sauce can help mask the dryness.
- What is the best way to thaw swordfish?
- Thaw swordfish in the refrigerator overnight to maintain its texture. Avoid quick-thawing in hot water or the microwave, which can start the cooking process prematurely.
