The Ingredients for Blackened Fish Tacos With Slaw
• Here’s everything you’ll need to make these flavorful tacos!
For the Taco Base
- Ahi Tuna Steaks – Use high-quality fish, which sears beautifully while keeping the center nice and pink.
- Vegetable Oil – Ideal for pan-searing; opt for olive or coconut oil for a twist in flavor.
- Flour Tortillas – The perfect base for our tacos; you can go with corn tortillas for a gluten-free version.
For the Blackened Seasoning
- Blackened Spice – A blend of sweet paprika, chili powder, kosher salt, and cayenne; using pre-made seasoning can save time if desired.
For the Cumin-Lime Slaw

- Lime – Fresh lime juice enhances the slaw’s brightness; always go fresh for the best flavor.
- Cumin – Adds earthy warmth; feel free to adjust the amount to suit your taste preferences.
- Cilantro (Chopped) – A fresh herb that brings everything to life; parsley can be a great substitute if cilantro isn’t your thing.

- Sour Cream – Provides creaminess to the slaw; Greek yogurt offers a lighter alternative.
- Mayonnaise – Adds extra creaminess; you can skip it for a healthier version of the slaw.

Expert Tips for Blackened Fish Tacos With Slaw
-
Perfect Sear: Make sure your pan is hot enough before adding the tuna. A properly heated pan helps create that essential crust without overcooking the fish.
-
Don’t Overcrowd: Avoid placing too many tuna steaks in the pan at once. Overcrowding can lower the pan temperature and cause uneven cooking.
-
Adjust Heat Levels: If you’re sensitive to spice, start with less cayenne in the blackened seasoning and adjust to taste. Balance is key for these blackened fish tacos with slaw.
-
Fresh Ingredients: Always use fresh lime juice for the slaw to enhance its brightness; bottled juice can lack the same vibrant flavor.
-
Storage Insight: If you have leftovers, store the tuna and coleslaw separately in airtight containers to maintain freshness. Reheat the tuna gently to avoid drying it out.
-
Make It Your Own: Don’t hesitate to customize! Add layers like avocado or sliced jalapeños to elevate the flavor profile of your tacos.

Blackened Fish Tacos With Slaw Recipe FAQs
How do I know if my Ahi tuna steaks are fresh?
Absolutely! When selecting Ahi tuna steaks, look for bright, vibrant pink or red flesh without any dark spots or discoloration. The flesh should be firm to the touch and have a fresh, ocean-like scent. Avoid any steaks that appear dull or have a strong fishy odor, as these are indicators of age.
What’s the best way to store leftover Blackened Fish Tacos?
For optimal freshness, store your leftover blackened fish tacos in separate airtight containers. The cooked tuna can be kept in the refrigerator for up to 2 days, while the cumin-lime coleslaw should ideally be consumed within the same timeframe to maintain its crunch. Refrigerate at or below 40°F. If you have leftovers, I recommend combining the two just before serving for the best taste experience!
Can I freeze the blackened Ahi tuna?
Yes, you can freeze the seared tuna! First, wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. The wrapped tuna can be stored in the freezer for up to 3 months. When you’re ready to enjoy it, defrost it in the fridge overnight, then gently reheat in a skillet over low heat to maintain its tenderness. Keep in mind that the coleslaw is best fresh, so prepare it right before serving for crunch and flavor.
How can I make my tacos gluten-free?
Very! To make your Blackened Fish Tacos gluten-free, use corn tortillas instead of flour tortillas. Many brands offer delicious corn tortillas that will hold up beautifully under all those tasty toppings and add an authentic touch—a wonderful way to enjoy your meal without gluten!
What if I have a fish allergy?
If you or someone in your family has a fish allergy, you can certainly substitute the Ahi tuna with a different protein. Chicken is a fantastic option—just adjust the searing time accordingly. Or, for a vegetarian twist, try using grilled portobello mushrooms. The spices will shine through, leaving everyone satisfied.
What if my seared tuna isn’t cooking evenly?
Here’s how to troubleshoot: if your tuna isn’t searing evenly, ensure your pan is adequately preheated before adding the fish; a hot pan forms a quick crust. Avoid overcrowding the pan; I often recommend searing in batches if necessary. Simply give your tuna room to breathe, and let it sear undisturbed for 1 to 2 minutes per side. With these tips, you’ll achieve that irresistible blackened crust every time!
