Yes, fish absolutely gets tough, dry, and rubbery when overcooked because its proteins tighten, moisture evaporates, and natural oils cook out, leading to a chewy texture and bland flavor. The key is to cook fish until it's opaque and flakes easily with a fork, typically around an internal temperature of 145°F (63°C), but many chefs prefer slightly lower for a silkier texture.
For example, you could be cooking a salmon fillet for dinner, but you mistakenly overcook it, resulting in dry, chewy fish.
However, excessive thermal load (i.e., too long, too hot, or both) often comes with a culinary penalty. Fish overcooks easily, resulting in a pronounced cook loss and ensuing dry and tough texture.
Add Moisture: Drizzle the fish with a little olive oil, melted butter, or a sauce (like lemon butter or a cream sauce) to help reintroduce moisture. Serve with a Sauce: A flavorful sauce can mask the dryness. Consider options like tartar sauce, aioli, or a citrus-based sauce.
When you overcook fish, it can become dry, tough, and lack flavor. Overcooked fish loses its natural moisture, which can result in a dry and chewy texture. The proteins in the fish also begin to tighten, which can make the fish tough and rubbery.
As you prepare fish for baking, grilling, or frying, a marinade with olive oil can tenderize the fish to its softest and juiciest form. The process of marinating fish in an infused oil allows the fish to soak in the seasonings and liquids you add to the marinade, creating a truly delicious meal.
The rule 10-Minute Rule or Canadian Cooking Method is simple: cook fish for 10-minutes per inch of thickness. Then, flip the fish only once, halfway through the cooking time. Whether you plan to follow a recipe or not, start by measure the thickest part of the fish with a clean ruler.
Overcooked fish turns rubbery, dries out, and tastes fishy—definitely not appetizing. Aim to pull it off the heat just before it's fully done, letting it finish cooking on your plate. The ideal temperature for fish is around 145°F (I seem to remember from my restaurant days, check though), so pull it at about 140°F.
But once the energy reserves are used up, the replacement stops and depletion results. The protein components are then able to interact, the muscle attempts to contract, and it eventually becomes hard and rigid.
And if we open up the salmon, you can see that the salmon pulls away from the skin really nicely and look at it glisten. You know fish is cooked well when it's a little shiny. You can see a little bit of the white and it doesn't look dry because if your fish is dry, you just overcooked it.

Fish that seems tough when you bite into it is probably overcooked. As it moves from done to "overdone," the flesh continues to firm then shrinks, pushing out moisture, which evaporates and leaves the fish dry and chewy.
Typically, carryover for fish is a mere 5-degree difference on an already lower cooking temperature (135 degrees F). Too long of a rest and the fish will cool down past a comfortable eating temperature. If the recipe doesn't call for a rest, skip it.
One of the most frequent seafood cooking mistakes is overcooking. Seafood, especially fish, has a delicate texture that can quickly become dry and tough when exposed to high heat for too long. The Problem: Overcooked seafood loses its moisture and flavor, resulting in a rubbery texture.
Chefs recommend following the 10-minute rule. According to this rule, you should bake fresh fish for 10-minutes per inch of thickness. Chefs agree that following this rule is the simplest way to ensure you don't overcook fish.
Seafood, especially shellfish, gets tough when overcooked. Shrimp, scallops and the like are revived a little if you simmer them in a mixture of butter and lemon juice. Salmon and hearty fish like that will be alright if you add a creamy sauce or brush with butter.
Fish is considered done when it reaches an internal temperature of 145°F (63°C) at its thickest part. The flesh should be opaque and flake easily with a fork. Remember, fish continues to cook a little bit when removed from the heat.
The "5 Ps of Cooking" in professional kitchens usually refer to Planning, Preparation (Mise en Place), Presentation, Passion, and Pride, focusing on organization, skill execution, and attitude for efficient, high-quality results.
