They are designed to make your Cinco de Mayo unforgettable, ensuring every guest leaves with a satisfied smile and a craving for more.

The Secret to Unforgettable Flavor: Homemade Blackening Spice

At the heart of these incredible tacos is the rich, complex flavor of blackening spice. Originating from Cajun cuisine, this unique cooking method and spice blend transform ordinary ingredients into something extraordinary. The spice mix creates a bold, smoky, and slightly spicy crust on the fish, sealing in its natural juices and imparting an intense depth of flavor that is simply unparalleled. It’s a game-changer for any dish, elevating simple proteins to gourmet status.

While many excellent store-bought blackening spices are available, crafting your own blend at home allows for complete control over the flavor profile and ensures the freshest ingredients. I often make a large batch at the start of grilling season, so I always have it on hand when a craving strikes. This versatile seasoning is not just for fish; it works wonders on chicken, steak, shrimp, or even vegetables. A simple drizzle of olive oil, a generous sprinkle of this magic spice, and you’re ready to cook! For these tacos, we’re using delicate tilapia fillets, but feel free to experiment with your favorite firm white fish, such as cod, mahi-mahi, snapper, or even plump shrimp for an equally delicious result.

Crafting Your Own Blackening Spice Blend:

Making your own blackening spice is surprisingly simple and incredibly rewarding. The blend typically includes a mix of paprika, thyme, cumin, oregano, onion powder, garlic powder, salt, and black pepper. Each spice plays a crucial role: paprika provides color and a mild, sweet earthiness; thyme and oregano add aromatic, herbaceous notes; cumin introduces warmth and depth; and onion and garlic powder ensure an all-around savory base. The salt and pepper, of course, are essential for bringing all the flavors into harmony. Creating this mix ahead of time means less fuss on cooking day, allowing you to focus on the cooking process and enjoying the aromas that fill your kitchen.

The Perfect Counterpoint: Zesty Southwest Slaw

As much as I adore the richly flavored blackened tilapia, the true star of these tacos might just be the vibrant, refreshing Southwest Slaw. This isn’t just any coleslaw; it’s a symphony of textures and flavors that perfectly complements the spicy fish. Its crisp, cool profile acts as an ideal counterpoint to the warm, smoky fish, creating a balanced and harmonious bite every time. The slaw is packed with fresh ingredients, making it not only delicious but also wonderfully colorful and nutritious.

Our Southwest Slaw is a dynamic combination of readily available ingredients. It starts with a convenient pre-shredded green cabbage and carrot mix, making prep incredibly quick and easy. To this crunchy base, we add the sweet pop of corn, the earthy depth of black beans, the crisp sweetness of red pepper, and the subtle kick of minced jalapeno (with seeds removed for controlled heat). Finely chopped red onion adds a pungent bite, while a blend of kosher salt, ground cumin, and freshly ground black pepper enhances the overall flavor profile. A generous squeeze of fresh lime juice brightens everything up, providing that essential zesty tang.

But what truly ties this slaw together is the dressing: Sir Kensington’s Chipotle Mayo. If you haven’t tried it yet, you’re in for a treat! Its rich, creamy texture and fantastic smoky flavor are precisely what this slaw needs. It adds a layer of luxuriousness and a hint of smoky heat that elevates the entire dish. This versatile slaw is amazing not only on tacos but also as a refreshing side dish for your summer barbecues, potlucks, or any meal needing a burst of fresh flavor. You’re truly going to fall in love with its irresistible taste!

Tips for Perfect Blackened Fish and Tacos

Choosing and Preparing Your Fish:

Variety is Key: While tilapia is an excellent, mild-flavored choice that holds up well to blackening, don’t hesitate to try other firm, white fish like cod, mahi-mahi, snapper, or even halibut. Shrimp also blackens beautifully.
Pat Dry, Always: Before seasoning, always pat your fish fillets completely dry with paper towels. This is crucial for achieving that signature blackened crust. Moisture on the surface will steam the fish instead of searing it.
Generous Seasoning: Don’t be shy with the blackening spice! A generous coating is key to developing that robust flavor and crust.
Resting Period: Allow the seasoned fish to sit at room temperature for about 15 minutes before cooking. This helps the flavors meld and ensures more even cooking.

Mastering the Blackening Technique:

Hot Pan is Essential: Use a heavy-bottomed skillet, preferably cast iron, and heat it over medium-high heat until it’s very hot but not smoking excessively. Blackening requires high heat to achieve the crust.
Don’t Overcrowd the Pan: Cook the fish in batches if necessary, to avoid lowering the pan temperature. Overcrowding will cause the fish to steam rather than sear.
Cook to Opaque: Blackened fish cooks quickly. Aim for about 3 minutes per side, or until the fish is opaque and flakes easily with a fork. Be careful not to overcook, as this can make the fish dry.
Ventilation: The blackening process can produce some smoke. Ensure good ventilation in your kitchen by opening windows or using an exhaust fan.

Assembling Your Tacos:

Warm Tortillas: Warm your tortillas just before serving. Spraying them lightly with nonstick cooking spray and browning them slightly in a skillet over medium heat adds flavor and makes them more pliable. You can also warm them in the microwave or oven.
Layering for Success: Start with a base of flaked blackened fish, then pile on a generous amount of the Southwest Slaw. This layering ensures you get all the flavors and textures in every bite.
Garnish with Freshness: Don’t forget the fresh lime wedges! A squeeze of fresh lime juice over the assembled taco brightens all the flavors. Crumbled Cotija cheese adds a salty, tangy finish, if desired. Avocado slices or a dollop of fresh salsa can also be wonderful additions.

2 tsp. garlic powder
2 tsp. salt
2 tsp. black pepper

Fish:

1 lb. tilapia fillets
2 Tbsp. olive oil

To serve:

8 flour tortillas (I like to spray my tortillas with nonstick cooking spray and lightly brown on both sides in a skillet over medium heat.)
Lime wedges
Cotija cheese, crumbled (if desired)

Instructions

Slaw:

Combine all slaw ingredients in a large bowl. Toss well. Cover bowl with plastic wrap and place in refrigerator to chill for at least 15 minutes, allowing flavors to meld. This recipe makes a generous portion of slaw. Store remaining slaw in an airtight container in the fridge for up to two days.

Blackening Spice:

In a small bowl, combine all ingredients (paprika, thyme, cumin, oregano, onion powder, garlic powder, salt, black pepper) until well blended. Store any remainder in a small, airtight jar for future use.

Fish:

Pat tilapia fillets completely dry with paper towels. Drizzle each fillet generously with olive oil, then sprinkle generously with the prepared blackening spice on both sides. Let fish sit at room temperature for 15 minutes before cooking.
In a large, heavy-bottomed skillet (preferably cast iron), heat 1 tablespoon of olive oil over medium-high heat until very hot but not smoking. Add the fillets to the hot pan without overcrowding. Cook for approximately 3 minutes per side, or until the fish is opaque throughout and a dark, flavorful crust has formed. Remove from pan and place on a plate. Flake fillets with a fork into bite-sized pieces. Repeat with remaining fish if cooking in batches, adding more oil if needed.

Assembling Tacos:

Warm your tortillas according to your preferred method (skillet, microwave, or oven). Top each warm tortilla with a portion of the flaky blackened fish.
Spoon a generous amount of the prepared Southwest Slaw over the fish.
Serve immediately with crumbled Cotija cheese and fresh lime wedges for squeezing.
