Step‑by‑Step Instructions for Blackened Fish Tacos with Cilantro Slaw and Sriracha Mayo

Step 1: Prepare the Spice Rub
In a small bowl, combine 2 teaspoons of chili powder, 2 teaspoons of paprika, 1 teaspoon of ground cumin, and 1 teaspoon each of garlic powder and onion powder. Add ½ teaspoon of pepper, ½ teaspoon of salt, and ¼ teaspoon of cayenne pepper for a touch of heat. Blend the spices thoroughly, then rub the mixture generously onto both sides of the thick-cut cod fillets, ensuring they are fully coated.

Step 2: Cook the Fish
Heat a large skillet over medium-high heat and add 1 tablespoon of olive oil and 1 tablespoon of unsalted butter. Allow the mixture to bubble, indicating it’s ready. Place the seasoned cod in the skillet and cook for about 4-5 minutes on each side until the fish is golden brown and flakes easily with a fork. Look for a slight char on the outside for that perfect blackened finish.

Step 3: Make the Slaw
While the fish cooks, prepare the slaw by combining 2 cups of shredded cabbage, the juice of ½ lime, and ¼ cup of chopped cilantro in a medium bowl. Season the mixture with salt and black pepper to taste, mixing well until the cabbage is well coated and vibrant. Set aside to allow the flavors to meld and stand out while the fish finishes cooking.

Step 4: Prepare Sriracha Mayo
In a small dish, whisk together ½ cup of low-fat mayonnaise, the juice of ½ to 1 lime, 1 tablespoon of sriracha, and 2 teaspoons of sugar until smooth. Taste the mayo and adjust the lime juice or sriracha according to your spice preference. This creamy concoction will elevate your Blackened Fish Tacos with a zesty kick.

Step 5: Assemble Tacos
To assemble the Blackened Fish Tacos, take 6-inch tortillas and place about 3 ounces of the blackened cod in the center of each tortilla. Generously top with the cilantro slaw and add a tablespoon of the spicy sriracha mayo on top. Wrap up your delicious creations, and serve them immediately to enjoy the fresh flavors and contrasting textures.
