FISH. TACOS. Need I say more?

I can’t be the only one who skims the dinner menu when dining out until my eyes catch some kind of fish on the menu. And if we’re at Mexican restaurant, any kind of seafood tacos are the first thing I look for.  If the avocado comes with? SOLD x 1000. Can we just start a petition to get avocado and/or guacamole to ALWAYS COME WITH? I mean, for real. Even if you sneak it into the price of the dish, I don’t care. I just want the freaking avocado, always. I will never not want the avocado, so please… PLEASE restaurants just include the avo.

Okay, now that I’ve covered my love for avocado, let’s talk about my love for fish tacos… more specifically these Easy Blackened Mahi Mahi Fish Tacos. I honestly hadn’t had fish tacos in so long until I made these, and I forgot how amazing they are! You honestly can’t go wrong with mahi mahi. It’s light, has great texture, and I don’t find it “fishy” at all. Plus using the blackened seasoning is a great way spice things up. I used a simple combination of spices that I gathered mostly from this recipe…

  • paprika
  • sea salt
  • onion powder
  • garlic powder
  • cayenne
  • black pepper
  • dried oregano
  • dried thyme
  • a touch of cumin (I added because I just really like it) 😉

Then you can just save whatever is left over in an airtight container and store it with the rest of your spices.

To prepare the fish, it’s best if your fillets are completely thawed, then patted dry with a paper towel before adding the seasoning. And don’t be afraid to go heavy on the seasoning if you like lots of flavor. It creates a nice coating when the fish are frying in the pan. Truth be told, I am kind of a baby when it comes to heat, which is why I like to load up my tacos with avocado and typically a creamy dressing.

Oh! And if you want perfectly shaped/folded tacos like these bad boys you see here, all I did was fold over the taco shells upside down, side-by-side, over a preheated oven rack for about 10 minutes, and you have yourself some LEGIT shaped shells. I’m not gonna lie, that was my first time attempting that (don’t ask why, I guess I’m just too lazy if I am not photographing :-p) and I was rather impressed with myself and felt pretty fancy.

    My wife loves blackened mahi-mahi tacos. However, she HATES avacado and cilantro! No, really – as much as you like it, she finds it disgusting. So had to alter recipe a bit.
    Still tasty…
