How to Make a Homemade Blackened Seasoning
As I’ve gotten older and a lot more patient, mostly due in part to having a 3-year-old, I’ve been enjoying more and more the entire cooking process and the same goes with these tacos. Whether that’s prepping everything beforehand or cleaning up, or making a simple blackened seasoning like in this recipe. Maybe it’s just pride in my cooking or my kitchen, but I’m enjoying the cycle in its entirety.
The crazy thing is that it can be any recipe too, even a grilled cheese for crying out loud. I never thought I’d be at this point in my cooking career but I remember reading about it from my favorite chef, Thomas Keller who literally started to feel the exact same transition and his joy for all things cooking. I think the foregone conclusion is that I’m getting old, DANG IT! Yup, I even enjoy making blackening seasoning.
Since we’re finally coming out of the cold everyday weather I wanted to spice a few things up. It’s literally been soup and root vegetables for the past 4 months and I couldn’t be happier about Spring being here. We are huge taco eaters in this family and we love trying out new recipes, so when I brought this up to Lindsay (my wife) she was like HECK YEAH!!!
I started it off by making my own blackened seasoning. Don’t be intimidated, it’s not hard I promise, and most likely you’ve got the ingredients to make it already in your pantry. If, however, you don’t want to mess with it and you’ve got a pre-made blackening seasoning that you already love then just use that in these blackened mahi-mahi tacos, no problem.
For the fish I went with Mahi Mahi and because it was literally unavailable fresh at 3 grocery stores I went with some really nice frozen fillets. I simply thawed them out and placed them on paper towels to soak up some liquid which makes it easier to saute. Just because the fish was frozen does not mean that these blackened fish tacos won’t be delicious.
Ok, so I’m gonna let you in on a little secret. Cabbage goes insanely well with fish tacos, especially these tacos… Between the crunchiness and flavor, it enhances fish tacos so much that it is a must every single time we make them.
The other thing I decided to add in the blackened these, was black beans. Simply strain, rinse, and heat up.
Now to start creating some yummy toppings! There are two things I wanted to put on top of these tacos, some sort of crema and salsa. For the crema, I mashed up some fresh avocados and whipped them with some Mexican Crema along with some lime juice salt, and pepper. It’s incredibly easy and packs a serious punch in the flavor department and will complement these blackened Mahi-mahi fish tacos to no end.
How to Make a Homemade Mango Salsa
The mango salsa I put together and added to the top of the blackened mahi-mahi fish tacos is to die for. I caught my father-in-law eating it with tortilla chips as a snack, but thank gosh I stopped him so we could use it for our tacos haha.
This salsa is a simple combination of mangos, jalapeños, red onion, green onions, and red bell peppers tossed in a little lime juice, olive oil, and salt and pepper. Just be sure to keep the salsa cool before serving. I’m not sure what it is but the sweetness from the mango just cuts the comfortable spice from the fish perfectly.
Cooking the Mahi Mahi Tacos
Cooking fish can be really tricky so here are my two cents. First, make sure it’s really dry before seasoning it. In my case, I patted the fish down with paper towels and dusted them on both sides with the blackening seasoning we made.
Next, get a large saute pan very hot on high heat and add in some cold oil. Once the oil begins to lightly smoke, turn the heat down to medium-high and place in your fish. Now, LET IT COOK!!! Don’t sit there and get worried and start moving things around, give it at least 3 to 4 minutes before attempting to flip it over.
After that amount of time I usually give the pan a little shake and if the fish easily moves the pan then I know I’m ok to flip over. When the fish is finished cooking I put them back on some paper towels to rest and to drain any unwanted oil.
How to Serve Mahi Mahi Tacos
It’s now time to dress everything up with as many or as few sides as possible…
For me, I go all in and add as much as I can possibly fit into each blackened Mahi-mahi fish taco. Sure I may look crazy eating it but it’s the best way to get all of the ingredients in one awesome burst of flavor.
My wife really only likes cabbage, fish, crema, salsa, and of course some cotija cheese. I leave the cheese garnished part up to whoever’s creating it because some people like more, some like less, and some like none at all because of the crema, the point is to have fun accessorizing this up and make it how you want to eat it.
In the end, we are loving our new kitchen and no matter what I’m making these days in there, I’m happy to be doing it, but wow were these blackened Mahi-mahi fish tacos such a treat!
