Ingredients
- 4 cod fillets (6 ounces each), about 1-inch thick
- 3 tablespoons paprika
- 2 tablespoons garlic powder
- 2 tablespoons onion powder
- 1 tablespoon dried oregano
- 1 tablespoon dried thyme
- 1 tablespoon cayenne pepper
- 1 tablespoon black pepper
- 2 teaspoons kosher salt
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 2 cloves garlic, minced
- Fresh lemon wedges for serving
- Fresh parsley for garnish (optional)
Instructions
- Combine all dried spices (paprika, garlic powder, onion powder, oregano, thyme, cayenne pepper, black pepper, and kosher salt) in a small bowl and mix together until well combined. This is your blackening spice blend.
- Pat the cod fillets completely dry with paper towels—this is crucial for getting a beautiful crust and preventing the fish from steaming.
- Sprinkle the blackening spice blend generously on both sides of each cod fillet, pressing gently so the spices adhere to the fish.
- Heat a large cast iron skillet over medium-high heat for about 2-3 minutes until it’s very hot. You should feel significant heat radiating from the pan.
- Add the olive oil and 2 tablespoons of the butter to the hot skillet and let them heat until the butter is foaming and the oil is shimmering, about 1 minute.
- Carefully place the seasoned cod fillets into the skillet, skin-side up, being mindful of any splashing from the hot butter.
Do not move the fish—let it sear undisturbed for 3-4 minutes to develop that gorgeous blackened crust.
- Using a thin spatula, gently flip each fillet and cook for another 2-3 minutes on the other side until the fish is cooked through and flakes easily with a fork.
- Add the remaining 2 tablespoons of butter and minced garlic to the skillet in the last minute of cooking, tilting the pan to baste the fish with the melted butter.
- Transfer the blackened cod fillets to a serving platter using a thin spatula, being careful not to break the delicate fish.
- Drizzle any remaining pan juices and browned butter over the top of the fish for extra flavor.
- Garnish with fresh parsley if desired, and serve immediately with fresh lemon wedges on the side.
Pro Tips
o Pat your fish completely dry before seasoning. Moisture is the enemy of a good crust and will cause the fish to steam rather than sear.
o Don’t flip the fish too early or too often. Let it sear undisturbed for 3-4 minutes on the first side to develop that gorgeous blackened exterior.
o Cod is a mild, delicate fish with a slightly sweet flavor that pairs beautifully with bold spices. If you can’t find cod, you can substitute halibut, sea bass, or mahi-mahi with excellent results.
o Make sure your spice blend is well-combined before applying it to the fish. The distribution of spices is what creates that restaurant-quality blackened crust.
o This recipe is best served immediately after cooking while the fish is still hot and the crust is at its crispiest.
o Leftover blackened cod can be stored in an airtight container in the refrigerator for up to 3 days and reheated gently in a 300°F oven.
o For a lighter version, you can use just 1 tablespoon of butter and rely more on the olive oil for cooking. The fish will be delicious either way.
o If you prefer less heat, reduce the cayenne pepper to 1 teaspoon. You can always add more spice next time if you want it bolder.
o Fresh lemon juice squeezed over the top right before serving brightens all the flavors and adds a pop of freshness that complements the blackened spices perfectly.
