San Antonio Restaurant + Blackened Fish Tacos
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 in the tacos 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 with a fresh avocado sauce.
Avocado Sauce for Tacos
Since the blackened fish is a little on the spicy side, a creamy avocado sauce comes in handy to help tone down the heat in these tacos.
All you have to do is throw in the four avocado sauce ingredients (avocado, yogurt, cilantro, and lime juice) into a small food processor and voila!
You have super creamy, ultra flavorful, avocado sauce for 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.
