Ingredients You Need To Make This Recipe

Cilantro-Lime Slaw

• Red and Green Cabbage. This slaw is made with a combination of shredded red and green cabbage. You use pre-shredded cabbage or shred it yourself.
• Fresh cilantro. Chopped cilantro adds freshness and herbiness to the slaw.
• Fresh jalapeno. Seeded and finely chopped jalapeno is added to the slaw for a subtle touch of heat.
• Green onions. Chopped fresh green onion adds mild onion flavor and a fresh, grassy note.
• Mayonnaise. The base for the slaw dressing.
• Fresh lime juice. For acidity and tanginess.
• Granulated sugar. For a touch of sweetness to balance out the other flavors.
• Salt and cracked black pepper. To season the slaw.

Blackened Redfish

• Smoked paprika, onion powder, garlic powder, cayenne pepper, cumin, salt, black pepper, oregano, and thyme. These are the seasonings used to blacken the fish fillets.
• Redfish filets. These tacos can be made with any redfish variety, such as red snapper, red drum, or orange roughy. Rinse the fish and pat it dry with paper towels.
• Melted unsalted butter. To coat the fish so that seasoning sticks and creates a nice crust when blackened.
• Extra-virgin olive oil. To coat the skillet so that the fish does not stick.
• 4-inch tortillas. Each taco can be made with one flour tortilla or two stacked corn tortillas.

How To Make This Recipe

• Add the cabbage, cilantro, green onion, jalapeno, mayonnaise, lime juice, sugar, salt, and pepper to a medium bowl and mix with a wooden spoon or rubber spatula until all of the ingredients are combined. Refrigerate the slaw while you prepare the fish.
• Add all of the spices for the blackening seasoning to a small bowl and use a fork or small whisk to mix them together. Set aside.
• Heat two tablespoons of olive in a medium cast-iron skillet over medium-high heat. Rinse and pat the redfish fillets dry with paper towels.
• Brush each piece of fish with melted butter on one side and generously coat with the blackening seasoning and rub it into the fish with your hands. Repeat on the other side of the fish fillets.
• Immediately place the fish in the hot skillet and cook for 3-5 minutes until a dark crust forms. Flip the fish and cook for another 2-3 minutes until the fish is cooked through. Transfer the fish to a paper towel-lined plate.
• Heat a medium nonstick skillet over medium-high heat and toast the tortillas until warm and browned around the edges.
• Lay the tortillas out flat on a serving plate and top with flaked pieces of blackened redfish. Use tongs to top the fish tacos with coleslaw. Garnish with fresh chopped cilantro and enjoy!

What Fish Is Best for Fish Tacos?

I have discovered that just about any fish works great for fish tacos! However, flaky white fish is the most popular fish for tacos because of its mild flavor and light, flaky texture. Some of the best varieties of white fish for tacos are:

• Cod
• Snapper
• Grouper
• Flounder
• Mahi Mahi

Also try making tacos with salmon, tuna, or catfish if you want something a little less traditional!

What Is Redfish?

Redfish is a common term used to describe a number of different fish species. It is most commonly applied to deep-sea rockfish, red drum, and red snapper. Other types of redfish include:

• Ocean perch
• Blackfin snapper
• Orange roughy (this is the fish I used for these tacos!)

Redfish is mild and slighlty sweet and has a slightly delicate, flaky texture. This article goes into great detail about the flavor profile of redfish.

What Are the Best Toppings for Fish Tacos?

No fish taco is complete without fun,flavorful toppings! Some of my favorite toppings for tacos made with fish are:

• Slaw, such as jalapeno slaw or cilantro-lime slaw
• Flavored mayonnaise, such as sriracha mayo or chipotle mayo
• Crema sauce, such as lime or jalapeno crema
• Salsa, such as mango salsa or roma tomato salsa
• Fresh herbs, such as chopped cilantro, or fresh parsley

How To Blacken Fish

The term blackening fish refers to the process of coating fish in melted butter and spicy seasoning then cooking it in a hot skillet until a dark brown crust forms on the exterior.

Blackening is most commonly done to fish, chicken, and shrimp and is very popular in Cajun and Creole cuisine. You can purchase store-bought blackening seasonings or you can easily make your own at home - just check out our Best Homemade Blackening Seasoning recipe!

Variations and Substitutions

Feel free to try these tacos with different combinations of proteins and toppings. Instead of making these tacos with blackened redfish, try:

• Blackened shrimp
• Blackened chicken
• Fried fish
• Fried shrimp
• Fried oysters

What to Serve With Fish Tacos

There are many different sides that perfectly complement tacos made with blackened fish. Some of my favorites are:

• Black beans
• Cilantro-lime rice
• Mexican street corn
• French fries
• Sweet potato fries
• Hush puppies

Storing Instructions

I do not recommend storing fully assembles redfish tacos as the tortillas will become soggy from the fish and slaw liquids.

However, you can store leftover cilantro lime slaw and blackened redfish in separate airtight containers in the refrigerator for up to 3 days.

Notes

• You can use packaged, pre-shredded cabbage or you can shred your own cabbage at home. 
• You can also use 2 cups of packaged coleslaw mix to save time.
• Cook the fish immediately after coating it in the butter and blackening seasoning. Allowing it to sit will cause the butter to solidify and the seasoning to clump and fall off. 
• If using corn tortillas, stack two on top of one another when serving since they are much thinner than flour street taco tortillas.
• If you use regular taco-size tortillas, you will not get as many tacos.
• Leftover slaw and redfish can be stored in airtight containers in the refrigerator for up to 3 days.
