What You’ll Need

Gather these simple ingredients for a deliciously memorable meal:

2 Ahi tuna steaks
1 tbsp vegetable oil (for pan)
6 flour tortillas (warmed)
2 tbsp sweet paprika
1 tbsp chili powder
1 tsp kosher salt
1/8 tsp cayenne pepper (use 1/4 tsp if you like really spicy)
8-10 oz of mixed green and purple cabbage (bagged shredded cabbage works great)
1 lime
1 tsp cumin (plus more to taste)
2 tbsp chopped fresh cilantro
1/4 cup green onions (thinly sliced)
2 tbsp sour cream (for a healthier coleslaw, you can use Greek yogurt)
2 tbsp mayonnaise
Kosher salt and pepper to taste (I use about 1/2 tsp of each)

Let’s Make It Together

Warm the Tortillas: Start by warming your flour tortillas. You can either wrap them in foil and place them in a warm oven for about 10 minutes or quickly warm them in a skillet over low heat for a few seconds on each side. This makes them soft and pliable, perfect for holding all that delicious filling.
Cumin Lime Coleslaw: In a bowl, combine the shredded cabbage, juice from half the lime, cumin, chopped cilantro, and a sprinkle of kosher salt and pepper. Mix gently until everything is combined. This zesty slaw adds a bright freshness to your tacos.
Make the Blackened Seasoning: In a small bowl, whisk together the sweet paprika, chili powder, kosher salt, cayenne pepper, and a pinch of cumin. This seasoning blend packs a punch, creating that signature blackened flavor we love!
Searing the Blackened Tuna: Heat the vegetable oil in a skillet over medium-high heat. Pat the tuna steaks dry with a paper towel and coat them generously with the blackened seasoning. Once the oil is hot, carefully place the tuna steaks in the skillet. Sear for about 1-2 minutes on each side until a delicious crust forms but remains perfectly tender inside. Remember, the key to a great blackened tuna is a hot pan!
Slice the Tuna: After searing, let the tuna rest for a moment. Then, using a sharp knife, slice the steaks against the grain into thin strips. The vibrant color against the spicy exterior is mouthwatering!
Assemble Your Tacos: Now the fun part! On a warm tortilla, lay down some slices of blackened tuna, top with a generous amount of cumin lime coleslaw, drizzle with sour cream or Greek yogurt, and sprinkle with green onions. Finish with a squeeze of lime juice for that extra zing!

Variations & Creative Twists

Spicy Mango Salsa: Add a zesty twist with a fresh mango salsa. Mix diced mango, red onion, jalapeno, and cilantro for an added tropical flair.
Avocado Bliss: Slice up some ripe avocado to add creamy richness to each taco, balancing out the spice perfectly.
Different Proteins: Try this same preparation with grilled shrimp or chicken for a delightful variation.
Tortilla Swap: Use corn tortillas for a gluten-free option, or try lettuce wraps for a low-carb alternative that’s still brimming with flavor!

Chef Emma’s Helpful Tips

Make-Ahead Slaw: You can prepare the cumin lime coleslaw a day in advance to let the flavors meld beautifully. Just store it in the fridge until you’re ready to assemble.
Slicing the Tuna: For best results, use a sharp knife and slice against the grain to ensure tender bites.
Storage Suggestions: Leftover tuna can be stored in an airtight container in the fridge for up to 2 days. Reheat gently on the stovetop, or enjoy cold in a salad!
Tortilla Wrapping: If you have leftovers, wrap the tortillas tightly in foil to keep them soft and warm for any future taco nights.
