Step-by-Step Instructions
- Combine the Spices:
- Mix cumin cayenne sweet paprika chili powder black pepper and salt in a small bowl and stir until totally combined. The uniform mixture ensures each bite of fish gets the right balance of flavors.
- Season the Fish:
- Lay out your fillets and generously rub the spice mix over both sides pressing so it sticks and covers the surface thoroughly. This will make a crust that blacks perfectly in the pan.
- Heat the Pan:
- Pour the olive oil into a large skillet and place it over medium heat. Wait two minutes so the oil shimmers but does not smoke. This ensures maximum crisp without burning the spices.
- Cook the Fish:
- Add the seasoned fillets to the hot skillet. Let them cook for five to seven minutes per side without turning until the crust is dark and you see the bottom edges turning opaque. Flip gently with a thin spatula and let the other side cook until the fish flakes with a fork.
- Rest and Serve:
- Transfer the fish to a plate and let it rest for two minutes so the juices settle. Serve right away with fresh salsa or a squeeze of lime for extra tang.

Crispy blackened fish was always a treat in our house but I especially love the contrast of smoky spicy crust and delicate white fish. My kids would line up in the kitchen the minute they smelled those spices toasting in the skillet.
Storage Tips
Chill any leftovers by placing blackened fish in a shallow covered container. This helps it cool quickly and safely. It keeps well for two or three days in the fridge. For longer storage wrap each fillet in plastic and slide into an airtight container or freezer bag to keep for up to one month. Reheat gently in a skillet so the crust stays crisp.
Ingredient Substitutions
You can swap white fish for salmon or snapper if you prefer a richer flavor. If paprika is missing try smoked paprika for a deeper aroma. Avocado oil works in place of olive oil if you need a higher smoke point.
Serving Suggestions

A fresh salsa or chunky avocado salad is my favorite way to brighten up this spicy fish. It also pairs well with rice tortillas or atop a big green salad for a lighter meal.
Cultural and Historical Context
Blackened fish comes from Cajun cooking traditions in Louisiana where seasoning blends and very hot pans help lock in flavor. The blackened crust is not burnt but rather a special seared coating formed by spices toasting quickly which protects the fish inside.
