Cooking fish can be a delicate process, and achieving the perfect doneness can be a challenge. One of the most common methods of cooking fish is by boiling it in water. But how long does it take to cook fish in boiling water? The answer depends on several factors, including the type of fish, its thickness, and the desired level of doneness. In this article, we will explore the different factors that affect the boiling time of fish and provide a comprehensive guide to cooking fish to perfection.
Factors Affecting Boiling Time
Several factors can affect the boiling time of fish, including:
Thickness of the Fish
The thickness of the fish is one of the most significant factors that affect its boiling time. Thicker fish fillets or steaks take longer to cook than thinner ones. As a general rule, fish that is less than 1 inch (2.5 cm) thick will cook faster than fish that is over 1 inch (2.5 cm) thick.
Measuring Fish Thickness
To measure the thickness of the fish, place it on a flat surface and use a ruler or a meat thermometer to measure its thickness. Make sure to measure the thickest part of the fish, as this will give you an accurate estimate of its boiling time.
Type of Fish
Different types of fish have varying densities and fat contents, which can affect their boiling times. Fatty fish like salmon and mackerel tend to cook faster than lean fish like cod and tilapia.
Fatty Fish vs. Lean Fish
Fatty fish have a higher fat content than lean fish, which makes them more tender and flavorful. However, they also tend to cook faster than lean fish. Lean fish, on the other hand, have a lower fat content and tend to be firmer in texture. They may take longer to cook than fatty fish.
Desired Level of Doneness
The desired level of doneness is another factor that affects the boiling time of fish. Fish can be cooked to different levels of doneness, ranging from rare to well-done.
Cooking Fish to Different Levels of Doneness
Fish can be cooked to different levels of doneness, depending on personal preference. Here are some general guidelines for cooking fish to different levels of doneness:
- Rare: 2-3 minutes per side

What is the general rule for boiling fish?
The general rule for boiling fish is to cook it for 8-10 minutes per inch of thickness. This rule applies to most types of fish, but it’s essential to note that the cooking time may vary depending on the fish’s density and your personal preference for doneness. For example, delicate fish like sole or flounder may require less cooking time, while thicker fish like salmon or cod may need more time.
It’s also important to consider the fish’s starting temperature. If the fish is frozen, it will require longer cooking time than if it’s fresh. Additionally, if you’re cooking a large piece of fish, you may need to adjust the cooking time accordingly. To ensure the fish is cooked to perfection, it’s always a good idea to check its internal temperature, which should reach 145°F (63°C) for food safety.
How do I determine the thickness of the fish?
To determine the thickness of the fish, you can use a ruler or a fish gauge to measure its thickest part. Make sure to measure the fish at its thickest point, usually near the spine. If the fish has a varying thickness, you can use the average thickness to estimate the cooking time. For example, if the fish is 1 inch thick at its thickest point and 0.5 inches thick at its thinnest point, you can use 0.75 inches as the average thickness.
When measuring the fish, make sure to pat it dry with a paper towel to remove any excess moisture. This will help you get an accurate measurement and prevent the fish from steaming instead of boiling. Additionally, if you’re cooking a fillet, you can measure its thickness at the thickest part, usually near the center of the fillet.
What is the best way to check if the fish is cooked?
The best way to check if the fish is cooked is to use a food thermometer to check its internal temperature. The internal temperature of the fish should reach 145°F (63°C) for food safety. You can insert the thermometer into the thickest part of the fish, avoiding any bones or fat. If you don’t have a thermometer, you can also check the fish’s flakiness and opacity. Cooked fish should flake easily with a fork and be opaque throughout.
Another way to check if the fish is cooked is to check its texture. Cooked fish should be firm to the touch and slightly springy. If the fish feels soft or mushy, it may be undercooked or overcooked. Additionally, you can check the fish’s color, which should be opaque and white. If the fish is still translucent or pink, it may not be cooked enough.
Can I boil fish with its skin on?
Yes, you can boil fish with its skin on, but it’s essential to note that the skin may not peel off easily after cooking. If you’re planning to serve the fish with its skin on, make sure to scale the skin before cooking to remove any loose scales. You can also score the skin in a crisscross pattern to help it cook more evenly.
Boiling fish with its skin on can help retain its moisture and flavor. However, if you’re planning to remove the skin after cooking, it’s best to cook the fish without its skin. This will make it easier to remove the skin and prevent it from sticking to the fish. Additionally, cooking the fish without its skin can help it cook more evenly and prevent the skin from becoming tough or rubbery.
How do I prevent the fish from breaking apart while boiling?
To prevent the fish from breaking apart while boiling, you can use a few techniques. One way is to use a fish basket or a steamer basket to hold the fish in place. This will help the fish cook evenly and prevent it from breaking apart. Another way is to wrap the fish in cheesecloth or a clean cotton cloth to hold it together.
You can also use a gentle boiling method, such as poaching or simmering, to cook the fish. This will help the fish cook slowly and gently, reducing the risk of it breaking apart. Additionally, you can add a little acidity, such as lemon juice or vinegar, to the water to help the fish hold its shape. This will help the fish’s proteins coagulate and hold it together.
Can I boil frozen fish?
Yes, you can boil frozen fish, but it’s essential to note that the cooking time may be longer than for fresh fish. Frozen fish can be cooked straight from the freezer, but it’s best to thaw it first to ensure even cooking. If you’re cooking frozen fish, make sure to adjust the cooking time accordingly, usually adding 50% more time to the recommended cooking time.
When boiling frozen fish, it’s essential to check its internal temperature to ensure it reaches 145°F (63°C) for food safety. You can also check the fish’s texture and flakiness to ensure it’s cooked through. Additionally, make sure to pat the fish dry with a paper towel before cooking to remove any excess moisture. This will help the fish cook more evenly and prevent it from steaming instead of boiling.
How do I store boiled fish?
Boiled fish can be stored in the refrigerator for up to 3 days or frozen for up to 3 months. To store boiled fish, make sure to cool it to room temperature first to prevent bacterial growth. Then, wrap the fish tightly in plastic wrap or aluminum foil and refrigerate or freeze it.
When storing boiled fish, it’s essential to keep it at a consistent refrigerator temperature below 40°F (4°C) or freezer temperature below 0°F (-18°C). You can also store boiled fish in a covered container, such as a glass or plastic container, to prevent moisture and other flavors from affecting the fish. Additionally, make sure to label the container with the date and contents to ensure you use the fish within the recommended storage time.
