Taco Night Shenanigans 

My family and I love to eat tacos. They are such a great family dinner that is customizable for each person. Now, there are a few reasons that I will make this specific taco, and any of those could be:

  1. Taco Tuesday comes every week. 
  2. I’m craving fish.
  3. We have friends coming over. 
  4. My kids’ friends are eating dinner with us.

I have also never met a taco I didn’t like. And this taco is just one of those amazing recipes that are almost like a specialty dinner treat. 

All these things together mean I’ve got one heck of a fish tacos recipe for you today.

What Happened To Fish Tacos?

A friend recently informed me that I did not have enough fish taco recipes on my website.

I’ve posted shrimp tacos, veggie tacos, and carnitas tacos, but he was right… I only have one classic fish tacos recipe here on ASP.

My bad. See? I need good people in my life to keep me in line. Also to keep my recipes in check and make sure I fill my website with recipes for everyone! So today I’m sharing one of my latest fish taco variations, a Buffalo BBQ Ahi Tuna Fish Tacos Recipe with crisp celery slaw and blue cheese.

This is so quick and simple, guys.

How To Make These Ahi Tuna Fish Tacos

1. Simply marinate thinly sliced celery and green onions in apple cider vinegar and honey, for a crunchy and tangy slaw that complements the “buffalo” element of the fish tacos recipe.

2. Stir a little barbecue sauce and cayenne pepper sauce together to coat the ahi tuna.

I find the combination of sweet barbecue sauce and the hot pepper “buffalo” sauce brings out the best in the Ahi, without overpowering it with heat or sweetness.

3. Quickly sear the ahi tuna until just medium-rare (or rare) and toss in  the buffalo bbq sauce to coat the ahi. 

4. Then serve each fish taco in a warm puffy wheat tortilla with the celery slaw and generous sprinkling of creamy blue cheese.

This is fusion food at its finest. Latin and American inspired fish tacos that cook up in minutes!

Frequently Asked Questions

Can I use a different type of fish? 

You most definitely can change the type of fish in this recipe! There are so many different varieties of fish that you can use, so feel free to experiment! Just be cautious about where you get your fish, so it is very fresh, and make sure to cook it thoroughly. 

Can you eat Ahi Raw? (or Partially Cooked?)

Yes. Look for fresh sushi-grade ahi to be sure it is safe to eat raw or medium-rare, with just a light searing on the outside.

How do I know if the fish is fully cooked? 

This recipe is meant to be partially cooked (seared) with sushi-grade tuna. Of course, you could cook the ahi a little longer to become fully cooked. However, with most fish varieties you will want to cook it through. If you have any specific questions, please refer to my How To Cook Fish Perfectly post!

Buffalo BBQ Ahi Fish Tacos Recipe with Celery Slaw and Blue Cheese!
Servings: 12 tacos



  • Start with the celery slaw: Slice the celery and green onions and place them in a medium bowl. Add the vinegar and honey, then stir in 1/3 teaspoon of salt, and pepper to taste. Stir well and set aside.
  • Mix the barbecue sauce and pepper sauce in a second bowl. Cut the Ahi tuna into small 1/2-inch cubes and sprinkle with salt. If you like your tortillas warm and puffy, flash fry them before cooking the Ahi.
  • Place a nonstick skillet over medium-high heat. Once the skillet is hot, add half the Ahi  and sear for 30-60 seconds per side, flipping once, for a rare to medium-rare interior. Once the Ahi is cooked to your liking, pour in half the buffalo barbecue sauce and toss. Scoop the ahi onto a plate, wipe out the skillet, and repeat with the remaining Ahi.
  • To serve: Scoop celery slaw into warm tortillas, top the slaw with the buffalo barbecue ahi, then sprinkle with crumbled blue cheese. Serve warm.
