Pan-frying fish is a quick and easy way to bring a tasty, light, and flavorful dish to the table without too much effort: you can choose between fillets, whether fresh, frozen, or home-frozen, or whole fish, calculating the size of the holder based on quantity and size. Obviously, as with many seemingly simple preparations, mistakes can lurk that lead to a less-than-exciting result: in this case, we're dealing with a delicate raw material—no matter what fish species you choose—that risks spoiling, becoming tasteless and stringy. Let's look at the mistakes you can make and how to avoid them.
1. Cooking Fish Straight Out of The Fridge

When you have good fresh fish, a mistake that could damage its texture and flavor is to cook it directly in the pan immediately after removing it from the refrigerator. Just like meat, fish flesh also needs to acclimatize briefly to soften the fibers that have stiffened during the low temperatures. Ten minutes or so is enough to prevent uneven cooking or a rubbery texture. Frozen fish purchased at the supermarket, on the other hand, can usually be pan-fried immediately (see the instructions on the package), while home-frozen fish is best thawed in the refrigerator for the necessary time and then proceed as with fresh fish.
2. Not Patting it Dry Before Cooking

Patting the fish dry with paper towels before cooking is a crucial step, as it allows for better browning and prevents the fish from boiling. The water on the surface, when it comes into contact with the heat, generates steam, which makes the meat excessively moist and prevents the formation of a delicious crust.
3. Putting It in a Cold Pan

To avoid ruining the fish flesh, it is important that the pan is properly heated when transferring it to the pan: this is an important detail because it prevents the fish from cooking too aggressively on the outside and unevenly, with the risk of the flesh sticking to the bottom and tearing.
4. Using Too Much or Too Little Oil (Or Butter)

Even if you're using a nonstick pan, it's always a good idea to grease the bottom with a light layer of oil or a knob of butter. Once added, the fish will begin to sizzle, browning on the outside while remaining soft on the inside. To achieve this, it's helpful to balance the amount of fat you use: too much may cause the fish to fry, while too little may cause the fish to stick and burn.
5. Turing It Continuously

Often, precisely because of the fear that the fillet will stick and burn, people tend to move it frequently. This is the wrong thing to do, especially when it comes to searing, as the meat (like a steak or hamburger) needs to remain still in contact with the heat to form the aforementioned crust. Furthermore, fillets and steaks are delicate and break easily.
6. Adding Salt at The Wrong Time

Salt is an ingredient used to add flavor, but we know it's hygroscopic, meaning it tends to attract water. Adding it at the beginning of cooking can encourage the release of liquids, drying out the flesh and resulting in a stringy fish. We recommend adding salt at the end, or adding it to a simple emulsion of extra virgin olive oil and lemon juice, brushing or marinating the flesh for a few minutes so it doesn't come into direct contact with the salt.
7. Cooking It For a Long Time

The advantage of pan-fried fish is that it creates a delicious dish in a short time. Depending on the type, fillets are ready in about 10-15 minutes, with fatty meat (such as salmon) requiring a few minutes longer than leaner, more delicate white meat. Even whole fish can be served in less than 25-30 minutes. So be careful not to let the clock go by, or the flesh will flake and dry out.
8. Not Seasoning It Properly

Pan-fried fish is a simple dish, but not banal, because there are actually many ways to serve it. Any ideas? You can enhance the natural flavor of the flesh with marinades, using the sauce to season even before serving, as for example in swordfish with salmoriglio. Or opt for a fresh sauce, enriched with cherry tomatoes and olives, for a white sauce flavored with aromatic herbs, or deglaze with wine or broth: in these cases, remember to brown the fish first and then add the watery or liquid ingredients, so as not to end up with stewed fish. The pan is also excellent for breaded versions, not fried or baked: try breaded tuna, coated only in breadcrumbs, for a light and tasty recipe.
