Blackened fish tacos are paired with a refreshing avocado, cilantro and lime sauce for an epic taco combo! They make a great healthy gluten-free dinner or lunch recipe and can be made with tilapia, cod, or any other white-fleshed fish.
Growing up in Southeast Texas, on the border with Louisiana, exposes you to SOOO many different flavors.
We have Cajun and Mexican food influences, the best BBQ and Tex-Mex you’ll ever find, and all of the fresh seafood you can imagine.
When Cohl and I lived in San Antonio, while attending dental school, we LOVED going to this popular restaurant called The Cove.
My all-time favorite dish to get there was their blackened fish tacos.
The blackened fish had a nice kick and the cabbage slaw helped to calm it down. Match. Made. In. Heaven.
Taking what I know best about Texas and eating in the South, I combined the flavors of Cajun, Mexican, and seafood to create these delicious blackened fish tacos.
What Kind of Fish Do I Use in these Blackened Fish Tacos?
For this particular version of these blackened fish tacos, I used fresh tilapia fillets.
However, since tilapia does not have a ton of nutritional value, feel free to swap it out for any other type of white-fleshed fish you prefer.
Some other varieties of fish you can try include:
- Cod (Vitamin B & Omega-3s)
- Mahi Mahi (Vitamin B, Omega-3s & Iron)
- Snapper (Vitamin A & Omega-3s)
- Catfish (Omega-3s)
Want to Save Some of these Blackened Fish Tacos for Later?
Word to the wise here… Do not pre-make all of your blackened fish tacos with avocado sauce with the intention of heating them up later! The corn tortillas WILL get soggy and very mushy <– Learned this the hard way.
Instead, you can assemble your tacos almost completely… Keep the avocado sauce on the side so you can add it AFTER you have re-heated your blackened fish tacos.
