How to get crispy skin on a fish fillet in a skillet?

Question

Im trying to make a quick weeknight supper with some store bought salmon and I want to get crispy skin on the fish fillet. Every time I sear it in my cast iron its skin turns out soggy instead of crunchy and sometimes it sticks to the pan. Do I need to dry it off with paper towels first or is their a better heat level to use on the burner?

Answer 1

Getting wonderfully crispy fish skin is all about controlling moisture, proper heat management, and a bit of patience. Drying the skin is actually the single most important step in the entire process.

First, take paper towels and press them firmly against both sides of the fillet, paying extra attention to the skin. Any surface moisture will turn into steam when it hits the hot pan, which prevents crisping and leads to soggy skin. If you have a few spare minutes, you can also gently drag the back of a chef's knife across the skin to scrape off excess moisture and wipe it away with a paper towel.

Next, preheat your cast iron skillet over medium-high heat until it is thoroughly hot. Add a thin layer of high-smoke-point oil, such as avocado, canola, or grapeseed oil, and wait until it shimmers. Season the fish with salt right before it goes into the pan—if you salt it too early, the salt will draw moisture out to the surface.

Carefully lay the fillet skin-side down, laying it away from you to avoid oil splatters. Immediately press down gently on the fillet with a flat spatula for about 20 to 30 seconds. Fish tends to contract and curl when heated, so holding it flat ensures the entire surface of the skin makes direct contact with the pan.

Once it is flat, lower your burner to medium heat. The key to preventing sticking in cast iron is simply leaving the fish alone. Proteins naturally stick at first, but as the skin crisps and renders out its fat, it will release freely from the iron. Do about 80 percent of your cooking on the skin side until you see the edges turn golden and opaque, then flip and finish the flesh side for just a minute or two.

First, pat the fillet down until it is totally bone dry because moisture ruins the crust. Get your cast iron skillet good and hot over medium-high heat with a high smoke point oil before the fish goes in. Press the fillet down flat with your spatula for thirty seconds so the skin does not curl up. Leave it completely untouched on medium heat until the skin releases naturally from the pan.

Answer 3

Drying the skin thoroughly with paper towels and preheating the skillet with oil on medium heat is necessary to make it crispy and prevent sticking.

Answer 4

You should dry the fish thoroughly with paper towels before placing it in the skillet, as removing surface water helps with the texture. I usually leave my prepped fillets uncovered in the refrigerator to dry the skin further. However, I am not entirely certain about the exact skillet temperature or pan preparation needed to ensure that it never sticks to cast iron.

Dry the fish real good with paper towls so its dry. Put oil in the hot skillet on mediem and let it sear till it un sticks on its own.
