Author Notes

A few years ago, Bon Appétit ran a story on “plancha”-style cooking featuring chef Eric Ripert and a slate-grilled summer menu. The photos of steak searing, sourdough bread charring, and all the summer vegetables caramelizing on a smoking-hot slab nearly had me running to Home Depot to buy untreated slate (as Ripert reportedly does), but as I read on, a more appealing idea caught my attention: I could use my cast-iron skillet instead. BA noted that a griddle or cast-iron pan set on a grill like a plancha allows “food to pick up smoky grill flavors without the risk of flareups” and is “particularly suited to delicate foods like fish and small vegetables that would otherwise fall through or be shredded by a grill grate.”

Last week, when summer finally hit upstate New York, and nothing sounded better than grilled fish, I remembered this article and set my cast-iron skillet on the grill as it preheated. About 10 minutes later, when the grill temperature had climbed to 550°F and the skillet had turned white hot, I poured in a little oil, carefully lowered in a haddock fillet, closed the grill, and set the timer for 3 minutes. Much to my delight, when the timer dinged, the fish had seared beautifully, the heat of the skillet creating a light bottom crust, which allowed the fillet to release from the pan with the gentlest push of a spatula.

Because I use a gas grill, no smoky flavor was imparted; nothing emerging from my grill will taste like burning briquettes or a summer campfire—but this is something I’ve come to accept about my backyard grilling undertakings. My gas grill, in essence, is a very hot outdoor oven that excels at searing without setting off the fire alarm; if you're working with a charcoal grill, I think the fish will be as good if not even better for the flavor of the coals.

In addition to haddock, I’ve had success using this method with fillets of cod and grouper, each about 1/2 to 1 inch thick. Seasoned with salt and cayenne pepper, the flaky fish can be eaten simply with a squeeze of lemon, though it’s particularly good broken into pieces over a bed of slaw and wrapped in tortillas warmed directly on the grill grates (which only takes about 30 seconds). With a simple slaw and crema, a summery skillet-grilled dinner can materialize in no time.

Note: On the fish, I like to use cayenne for both color and heat, but if you are sensitive to heat, you can use other dried spices such as paprika, cumin, or dried ancho chile. The slaw and crema can be made a day in advance. —Alexandra Stafford

Skillet-Grilled Fish Tacos With Cilantro-Lime Crema
  • Cilantro-Lime Crema
  • 1 cup (heaping) cilantro (about 1 ounce)
  • 2 tablespoons fresh lime juice, plus more to taste
  • 1 cup sour cream
  • 1 teaspoon sugar
  • 1/4 teaspoon kosher salt, plus more
  • Skillet-Grilled Fish Tacos
  • 1 pound fillet of haddock, cod, or grouper, 1/2 to 1 inch thick
  • Kosher salt
  • Cayenne pepper
  • 1 tablespoon (or more) grapeseed or other neutral oil
  • 2 to 4 tortillas (I like Whole Foods' soft corn tortillas)
  • Slaw, see above
  • Lime wedges, for serving
  1. Cilantro-Lime Crema
  2. Set a cast-iron skillet on a grill. Close the grill, set it to high, and let it heat up to 550°F or 600°F.
  3. In a food processor, pulse the cilantro and 2 tablespoons of the lime juice until finely chopped. Add the sour cream, sugar, and 1/4 teaspoon of the salt and purée until smooth. Taste, adjusting the seasoning with more salt or lime juice. Alternatively, finely chop the cilantro by hand, then add the lime juice, sour cream, sugar, and salt and whisk until smooth.
  1. Skillet-Grilled Fish Tacos
  2. If the fillet of fish is long, cut it in half so it will fit in your skillet. Season the fish generously with the salt on both sides. Season with the cayenne according to your heat tolerance—go light if you are sensitive to heat. Gather your tools for the grill: a reliable potholder, a spatula, a platter for the cooked fish, the oil, and the tortillas.
  3. Lift the lid of the grill. Pour the oil into the hot skillet—enough to coat the bottom in a thin layer. Using the potholder if necessary to bring the skillet closer to you, carefully lower the fish into the skillet. If you are slow and controlled, the oil won’t splatter.
  4. Close the lid. Set a timer for 3 minutes. Check the fish by prodding it with a spatula—it should flake fairly easily. If it doesn’t, close the lid and cook for 1 minute more. Remove the fish with a spatula, using the potholder as needed, and transfer to the platter.
  5. Turn off the grill. Throw the tortillas on the grill, leaving it open. Check after 20 seconds or so, flip, and cook for another 20 seconds, until the tortillas are soft and have nice grill marks on each side. Transfer to the platter.
  6. To serve: Spoon the slaw into the tortillas. Break the fish into pieces over the top. Drizzle with the crema. Squeeze lime wedges over top and serve with more wedges on the side.

sounds good, but where is the slaw recipe? It seems to be missing....

It’s in the author notes

I've made this a few times and love the combination of flavors between the slaw and cilantro dressing and the Cayenne pepper. As I recall the slaw was way more than we needed so I've cut back on the amount I make. Other than that, it's
simply yum!

Where is the slaw recipe? The presume the cilantro crema is tossed with a kind of vegetable but I can not see any reference to a cabbage, radish or green.
Ceege May 17, 2019
Apparently you are not the only one with this question. I asked the same one Aug. 21, 2016 and still have not received an answer......needless to say, I have not tried this recipe.
Alexandra S. May 17, 2019
The slaw recipe is linked in the Author Notes above:

It's linked in the notes above. Here you go!
Lorrie H. May 17, 2019
Here it is. The link was in the write up above. I had to look for it too!
Mary May 17, 2019
Thanks. No link on my iPad version. Maybe requires PC for link to upload. Sounds yummy.

I would think anyone could make a simple slaw.

Has anyone tried making these in a wood-fired pizza oven?
Toni O. August 18, 2020
Not yet, but it should be very similar and really tasty. I would recommend keeping the oven temp lower than 500˚. I use my cast iron skillet in my wood-fired oven all the time.
Tad August 22, 2017
I always wondered about putting any milk products on my fish and any Iberian I talked to about it said it's a no-no for them.
scoot87501 May 24, 2020
It's done in Mexico all the time.
Gretel July 11, 2021
perhaps a mayonnaise or aioli would be a nice substitution for the sour cream!
Kait R. July 26, 2017
Substituted sour cream with Greek yogurt – was a success!
gail April 14, 2017
Just made this tonight, it was great and taught me a new way to fry fish outside! What else can I use the slaw with as it was delicious also
Alexandra S. April 15, 2017
So happy to hear this! If you have leftover slaw, you could add poached, shredded chicken to it and more vegetables: shredded carrots, scallions, more herbs and turn it into more of a main course salad.
Lorrie H. September 14, 2016
My family and I loved this! The only change I might make is to skip the dressing for the slaw as the cilantro lime crema made enough for the slaw and for topping the tacos and was so yummy. Thanks for the recipe!
Alexandra S. September 14, 2016
Fantastic! So happy to hear this. Always nice to know when you can skip a step, too :)
Ceege August 21, 2016
How do I find the slaw to go with these fish taco' page only shows the
Cilantro-Lime Crema and Skillet-Grilled Fish Tacos.

Alexandra S. August 22, 2016
Sure thing! It's up in the notes section of the recipe, too, for future reference.
Cat50 August 21, 2016
These were amazing. The cilantro-lime crema was so good-we had the leftover crema on salads and ate the remaining slaw on it's own the next day! The only change I will make next time will be to probably just broil or pan fry the fish in a skillet as my well-seasoned (I thought) cast iron pan was a giant mess of stuck fish! If your pan isn't seasoned it will stick! This is a new, quick weeknight favorite. Thanks!
Alexandra S. August 21, 2016
So happy to hear this! Everything except the sticking of course :( Broiling is a great idea! Love the idea of drizzling the creme on salads. Yum.
Kevin F. July 10, 2016
Can't get enough of these tacos! Super easy to make, and they were a huge hit with the family. Loved the slaw recipe too, as I am a bit of a slaw nut and enjoyed trying this variation.
Alexandra S. July 10, 2016
So happy to hear this, Kevin! And I'm so glad you like the slaw, too. Thanks for writing in!
