Hey there, Seafoodies!
Somewhere in your kitchen is a pan that will outlive every other piece of cookware you own. Cast iron skillets get handed down through families, show up at estate sales looking better than the day they were made and only improve with use—and in the Dish on Fish kitchen, ours gets used most often for seafood. Cast iron holds heat like nothing else, gives fish a golden crust no other pan can match, cooks shrimp and scallops in a couple of minutes flat and moves from stovetop to oven without dirtying a second dish. The two were made for each other, which is why we put together this guide, including everything we’ve learned about making the pairing work!
It all starts with heat. Cast iron rewards a little patience up front, so preheat the skillet over medium-high for a few minutes, add a high-smoke-point oil like avocado or grapeseed and wait until it shimmers before anything goes in. A properly hot pan sets the crust the moment the fish touches it, and that crust is what lets the fillet lift right off when it’s ready. The other half of the equation is moisture, or rather the lack of it. Pat every fillet, shrimp and scallop completely dry with paper towels and salt right before cooking, because a dry surface sears and a damp one steams. That single habit will do more for golden edges than any gadget on the market.
Once the seafood is in the pan, the best thing you can do is very little. Lay it in away from you (skin-side down, if there’s skin), press gently for a few seconds and then let it be. Fish releases itself once the crust forms, usually in three to four minutes, and when the spatula slides under with no resistance, that’s your cue to flip—once. Thinner fillets, shrimp and scallops finish right on the burner. Thick cuts like halibut, sea bass and a hefty salmon fillet love a stovetop sear followed by a few minutes in a 400°F oven, and cast iron makes that handoff seamless. For a restaurant-worthy finish, add a pat of butter, garlic and herbs at the end and spoon that sizzling butter over the top!
Caring for the pan afterward takes about two minutes and keeps it in the family for decades. Let it cool slightly, rinse with hot water and scrub with a brush (a drop of dish soap is fine on a well-seasoned skillet), then dry it over a low burner, wipe on a whisper of oil and put it away. A quick lemon deglaze or a tomato-based dish like shakshuka is no problem for a seasoned pan; just clean and re-oil the same night.
The 11 recipes below put all of this advice to work: a Smoked Salmon Hash for slow weekends, Blackened Trout and Mahi Mahi for spice lovers, Spanish Garlic Shrimp that sizzles in about five minutes and a Pan-Seared Halibut with a side of white bean and gremolata that looks like it came from a little country bed and breakfast kitchen. Every one of them brings protein, omega-3s and vitamin D to the table—and cooking in a cast iron may even add a small amount of iron to the meal.
Here’s to the pan that lasts a lifetime and the dinners worth cooking in it!
Weekend brunch, handled in one skillet. Crispy potatoes get a head start, then smoked salmon joins the party for a hash that goes straight from the stove to the middle of the table—and yes, we’ve served it for dinner more than once.
Eggs poach right in a spiced tomato sauce flaked with tuna and the skillet keeps everything bubbling all the way to the table. Here’s a little trick: use tuna packed in olive oil and drain that oil straight into the skillet for an easy flavor boost.
This is the hands-off rule in action. Skin-side down, a gentle press, then patience—about four minutes later the salmon releases on its own with a crackling skin that will make the whole family clamour for who gets to eat the crispy edges first.
New to cast iron? Start here. Cod is mild, forgiving and ready in under 10 minutes; just serve with a side of potatoes any way you like them and your favorite vegetable for a complete meal!
This Spanish garlic shrimp takes its cues from gambas al ajillo, the beloved tapas dish that proves a few simple ingredients can deliver big flavor. Shrimp simmer in garlic-infused olive oil for a dish that’s bold, savory and ready in about 30 minutes.
Pan Seared Scallops with Lemon Butter
Restaurant scallops at home come down to two things: a screaming-hot skillet and scallops patted completely dry. Two minutes per side, 90 seconds in a swirl of lemon butter and you are ready to indulge.
Open a window before you start—blackening is a smoky business, and cast iron is the pan that does it best. The resulting peppery spice crust on tender trout is totally worth the effort and the leftovers make an excellent taco filling the next day.
This is your sign to give sea bass the skillet treatment. Get the pan warmed up, let the fish turn beautifully golden, then serve the fillet drizzled with the pan drippings, a sprig of cilantro and additional lemon to enhance the flaky bites all the way through.
Firm, meaty mahi mahi holds up wonderfully to a heavy hand with Cajun spices. Serve with a side of rice and beans, or save for your next Taco Tuesday and tuck it into warm tortillas with a spoonful of mango salsa.
Pan Seared Halibut With White Beans And Gremolata
When buttery halibut meets creamy beans and zingy gremolata, something delicious happens. See what we mean by adding this easygoing combination to your weekly menu and enjoy plenty of texture and flavor without overcomplicating dinner.
Pan-Roasted Fish Fillets With Herb Butter
The technique that works on nearly any fillet at the seafood counter. Sear, flip, then spoon sizzling herb butter over the fish until it’s just cooked through—once you’ve done it with black bass or haddock, you’ll want to try it with everything!
