Ingredients
Blackened Fish
2 white fish fillets, 6-8 oz each (such as cod, halibut, mahi-mahi, or tilapia)
1 tablespoon olive oil
Blackening spice blend
2 teaspoon paprika
2 teaspoon garlic powder
1 tablespoon cumin
(You can also use a pre-made blackening spice blend if you prefer.)
Jalapeño Crunch Slaw
⅓ cup rice vinegar
1 teaspoon salt
2 tablespoon granulated sugar
1 jalapeño, thinly sliced
½ small red onion, thinly sliced
Instructions
1. Prepare the slaw
Start by making the jalapeño slaw so the flavors have time to develop.
In a medium bowl, combine the rice vinegar, salt, and sugar, stirring until the sugar dissolves.
Thinly slice the jalapeño and onion. A mandoline can make this step quick and uniform, but use caution when slicing.
Add the jalapeño, and onion to the bowl and toss until everything is evenly coated.
Place the slaw in the refrigerator and allow it to marinate for 20–30 minutes. This softens the vegetables slightly while enhancing the tangy, spicy flavor.
2. Prepare the fish
Preheat the oven to 425°F (220°C).
Pat the fish fillets dry with a paper towel. Brush each fillet lightly with olive oil to help the spices adhere.
In a small bowl, mix together the blackening spices. Generously coat the fish fillets with the spice blend, pressing gently so it forms an even crust.
3. Bake the fish
Place the seasoned fish on a parchment-lined baking sheet.
Bake for 15–20 minutes, depending on the thickness of the fillets.
Fish is typically done when it flakes easily and reaches an internal temperature of 130–145°F, depending on your preferred level of doneness.
4. Assemble the dish
To serve, start with a bed of shredded cabbage or slaw mix on the plate.
Place the blackened fish fillet on top.
Finish with a generous scoop of the jalapeño slaw, allowing the tangy marinade to lightly dress the fish.
Serving Ideas
This dish is versatile and pairs well with a variety of sides:
cilantro lime rice

It can also be served as a fish bowl with grains and additional vegetables.
Tips for Best Results
Use firm white fish Cod, halibut, mahi-mahi, and snapper hold up well to the spice crust and baking method.
Let the slaw marinate Even 20 minutes makes a big difference in flavor and texture.
Adjust the spice level Reduce cayenne or remove jalapeño seeds if you prefer a milder dish.
Storage
Leftover fish and slaw can be stored separately in the refrigerator for up to 2 days.
Reheat the fish gently in the oven or skillet to maintain texture.
