Blackstone Mahi Mahi Tacos

Blackstone Mahi Mahi Tacos

Finally we had a day that wasn’t awful so I could make this healthy griddle recipe for Blackstone Mahi Mahi Tacos.

I got my Blackstone Flat Top Grill/ Griddle right before winter.

Although thankful and grateful to have one, it’s been killing me not being able to use it as often as I would like.

Yes, yes I could brave the cold temps and snow but I am SO much of a wimp when it’s freezing out.

How to Make Blackstone Mahi Mahi Tacos

These mahi mahi fillets were frozen from my local grocery store.

I just thawed them out and seasoned with cajun seasoning, chili powder, kosher salt, and pepper.

Set everything I needed for the grill on a tray and headed out to the patio.

Here’s how to make Blackstone Mahi Mahi Tacos

Preheat the Blackstone for a good 5 minutes on medium high heat.

Then a squirt of vegetable oil and the mahi mahi.

These will cook for 3 to 4 minutes on one side, then flip.

I keep a bottle at my grilling station with oil so I don’t have to carry it out each time.

Once flipped I added more oil to the grill and the street size corn tortillas.

The tortillas cook 1 to 2 minutes per side.

Once done, put everything back on the tray and head inside to assemble the tacos.

For the sauce I simply mixed tartar sauce with Sriracha for a spicy and tangy kick.

To each corn tortilla place some slaw or lettuce first then flake some of the fish to add over top.

Then a drizzle of the spicy tartar sauce and a lime wedge on the side.

Squeeze the lime over the Blackstone Mahi Mahi Tacos and enjoy!
