How to make blackened Gluten-free fish tacos
(Note: This is a step-by-step tutorial with pictures. For more specific instructions, along with ingredient amounts, see the recipe card at the bottom of the post.)
- First pat the fish dry by placing it on a paper-towel lined plate and blotting the top with more towels. Set aside.
- In a large ziplock bag, combine the olive oil and blackened spices. Massage the bag to combine and then add the fish. Move around the fish in the bag so the seasoning coats the fish well. Set aside while the slaw is made.
- For the coleslaw dressing, in a small bowl whisk together the lime juice, olive oil, honey, vinegar, salt and pepper.
- In a large bowl combine the slaw and cilantro. Pour the slaw vinaigrette over the top and stir to combine. Set aside for the flavors to meld and soften the slaw while the fish bakes.
- Bake at 425ºF for 10-15 minutes, depending on the thickness of your fish. Meanwhile, mix together the sour cream and sriracha for the creamy taco sauce.
- When the fish is done, divide it on the corn tortillas, top with slaw, and drizzle with the taco sauce.
FREQUENTLY ASKED QUESTIONS
If you do not need a gluten-free recipe, blackened fish tacos may be served on flour tortillas. Other gluten-free options, though, are served on corn hard shell tacos, over rice as a fish taco bowl, or on top of a salad for a low-carb fish taco salad. If you are looking for side dishes, find many recipes on this “What to Serve with Fish Tacos” post!
I generally use tilapia to keep it affordable, but cod, haddock, or pollock would also work great. Since these fish are thicker, they would have to bake about 5-10 minutes longer. For best fish for tacos options, check out this article!
Corn tortillas get a bad rap, but they are glorious when properly warmed up! My favorite method is to drizzle a dash of oil in a non-stick skillet and warm on both sides to lightly fry.
Try “charred” tortillas as another option. Turn on a gas stove burner and place the tortilla directly on the grate for about 20 seconds per side, using tongs to flip.
Every taco night I use this cheap kitchen must-have! A tortilla pouch is great for warming shells in the microwave or keeping already-warmed tortillas hot during dinner!
Yes. The slaw, taco sauce, and fish seasoning marinade may all be prepared ahead of time. However, I advise not letting the fish sit in the marinade more than 30 minutes because the lime’s acidity will start to “cook” the fish and break it down.

I’m new to the gluten free lifestyle and am not a big fan of cooking in general. I found this recipe while searching for something to make for dinner. I happened to have all the ingredients on hand and was able to make an awesome meal with barely any effort. No only was it quick and easy to make, it was delicious. I will definately be making this again.
