Blackened Cod
Bold, smoky, and just a little spicy – this blackened cod is the weeknight fish dinner that actually gets everyone excited. A homemade blackening seasoning made from pantry spices coats buttery cod fillets in a savory, slightly sweet Cajun-inspired crust, and the whole thing comes together in about 20 minutes. It’s perfect for busy weeknights, totally gluten-free, and versatile enough to serve with simple sides or tucked into fish tacos.
It’s your choice!
The homemade blackening seasoning is what makes this recipe – just eight pantry spices mixed together in about two minutes, and you get that perfect sweet, savory, and mildly spicy Cajun flavor that store-bought packets rarely nail.
That said, if you’ve got a blackening blend you love in your spice cabinet already, it works great here too, this is a flexible, forgiving recipe either way. It’s…
🌶️ Bold & smoky: Homemade blackening seasoning brings serious Cajun-inspired flavor to every single bite.
⏱️ Ready in 20 minutes: From fridge to table faster than any takeout order – and so much better.
🐟 Mild & family-friendly: Flaky cod takes on the bold spices beautifully, making it a win even for fish skeptics.
🌮 Totally versatile: Serve it with sides, stuff it into tacos, or pile it on a salad – it works every way.
🧂 Made with pantry spices: No special shopping needed – the whole blackening blend lives in your spice cabinet.
If you’re looking to enjoy more seafood in your life, panko salmon is one of our standards that always goes over well, and shrimp and orzo is a great weeknight option that includes seafood, veggies, and carbs!

Ingredient Notes
You’ll need some fresh ingredients and pantry staples to bring this blackened fish recipe to the table: cod fillets (fresh or frozen, both work well), butter, and a homemade blackening spice blend made from smoked paprika, sea salt, granulated sugar, black pepper, garlic powder, onion powder, dried oregano, and cayenne pepper.
Emily’s Tips & Tricks
- Pro tip: Pat your cod fillets completely dry with paper towels before seasoning – this is the single most important step. Any surface moisture will steam the fish instead of sear it, and you’ll lose that beautiful blackened crust entirely.
- Feeding kids without pressure: If blackened fish is new territory for your kids, start by serving a tiny piece in a small taster bowl alongside familiar foods you know they will eat – fruit, bread and butter, or whatever reliably goes over well at your table. Following the Division of Responsibility means you choose what’s served; they choose whether and how much to eat – no pressure to try or eat!
- Variations: Cod is delicious here, but any white, flaky fish works beautifully with this seasoning – red snapper, grouper, halibut, haddock, or flounder are all great options. You can also serve it a few different ways: flake it into corn or flour tortillas with guacamole and mango salsa for blackened fish tacos, or pile it onto a bun with shredded cabbage, mayo, and dill pickles for a fish sandwich.

Description
This blackened cod fish recipe is full of flavor and only made with a handful of ingredients. Serve with a simple side for a nutritious dinner.
Ingredients
- 4–6 oz. cod fillets (thawed)
- 1 tsp. smoked paprika
- 1 tsp. sea salt
- 1 tsp. granulated sugar
- 1/2 tsp. black pepper
- 1/2 tsp. garlic powder
- 1/2 tsp. onion powder
- 1/2 tsp. dried oregano
- 1/4 tsp. cayenne pepper
- 2 Tbsp. butter, divided
Instructions
- Pat fish dry with paper towel.
- In a small bowl, mix together smoked paprika, sea salt, sugar, black pepper, garlic powder, onion powder, dried oregano, and cayenne pepper.
- Melt 1 tablespoon of butter and brush it onto both sides of the fish, and sprinkle with seasoning on both sides.
- Melt remaining butter in a skillet over medium-high heat and cook fish for about 4 minutes, carefully flip over, and cook another 2-3 minutes, until cooked through and flaky.
Notes
Storage: Store leftover blackened cod in an airtight container in the refrigerator for 2–3 days. To reheat, warm in a hot skillet for best results, microwaving fish is not recommended.
Ingredients: Both fresh and frozen cod work well here – use whatever you have access to. Butter is traditional for the blackening method and gives the best flavor, but olive oil can be swapped in if needed.
Prep ahead: The blackening spice blend can be mixed up well in advance and stored in an airtight jar, making this an even faster weeknight dinner.
Tools: A cast-iron skillet is ideal for blackened fish. Its heat retention gives you that deep, even crust that’s hard to replicate in a regular pan.
Serve with: Napa cabbage slaw, simple lemon kale salad, haricot verts, or air fryer broccoli all pair beautifully. White rice alongside any of those keeps it simple and satisfying.
Serving Suggestions
There are so many ways to serve blackened fish! I like to keep it simple with a white rice and veggie, but it’s also really easy to turn it into a full meal. Here are a few ideas:
- Blackened Fish Tacos – Serve blackened fish pieces in corn or flour tortillas and top with guacamole, pickled red onions, or your favorite taco toppings like mango salsa.
- Blackened Fish Sandwich – Serve fish on a bun with shredded iceberg lettuce or crunchy cabbage and a mayo or tartar sauce and dill pickles.
- Veggie Sides – Haricot Verts, Napa Cabbage Slaw, Air Fryer Broccoli

My husband liked it alot, it was a little spicy for me (even though i used only the cayenne). I also cut both the salt and sugar by half.
I wasn’t certain what heat setting to use, i picked medium and it seemed like that was the right setting.
Thanks Lisa! Glad you enjoyed it and thanks for letting me know that the cooking temp was missing!
We liked this blackened cod! It was tasty, with a bit of crispness on the outside and the flavor was just right, not totally overpowering. Had your airfry potatoes and asparagus with it. Another winner Emily.
