Ready in just 20 minutes and truly easy to make, this is the perfect recipe to make on a busy weeknight. Halibut is a white-fleshed mild-tasting fish, and as a result, halibut recipes are often mildly flavored. I actually prefer bolder flavors. Happily, blackening turns this fish into an intensely flavorful dish that my entire family enjoys. My first time trying blackened fish was during a visit, a few years ago, to the American South. I really enjoyed the bold flavors of the dishes I tried there! So as soon as I returned from my trip, I started making this recipe at home.
Ingredients
You’ll only need a few simple ingredients to make this blackened halibut recipe. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need:
Spices: I like to use paprika (or smoked paprika), dried thyme, dried oregano, onion powder, garlic powder, and cayenne pepper.Kosher salt: If using fine salt, you might want to reduce the amount you use, or the fish could come out too salty.Halibut fillets: I like to use skin-on fillets. I find fish skin to be absolutely delicious. But if you’d rather use skinless fillets, that’s fine.Butter: For cooking the fish. You can also use a high-smoke-point oil such as avocado oil. But butter is more flavorful and will also better promote the blackening process thanks to the milk solids it contains.
Instructions
Making blackened halibut is truly easy! Scroll down to the recipe card for detailed instructions. Here are the basic steps:
In a shallow dish, whisk together the spices and the salt. You can use a small hand whisk or simply a fork.Next, sprinkle the halibut fillets with the spice mix and press to help the spices adhere to the fish.Fry the fish pieces in butter over medium-high heat until cooked through, about 3 minutes per side.Spoon the tasty pan juices on top of the fish and serve.
Expert tip
While you certainly want the fish to be cooked through, you don’t want it overcooked. Overcooked fish is dry and gummy. I find that 3 minutes on the first side over medium-high heat followed by 3 minutes on the second side over medium heat is perfect for 1-inch-thick fillets. You’ll probably need to adjust the cooking time according to the conditions in your own kitchen - how thick your fillets are and how hot your pan gets. I used to make this recipe on a gas cooktop and the fish needed about 4 minutes per side. Now I cook using a ceramic cooktop that gets considerably hotter (now I know why chefs prefer gas cooktops - those give you much better temperature control) and I find that I need to cook the fish for a shorter time.

Storing leftovers
If you have leftovers, you can keep them in the fridge, in an airtight container, for up to 3 days. Make sure you reheat them very gently though, so as not to dry out the fish. I usually reheat them covered in the microwave, on 50% power.
