Ingredients needed for my best fish tacos recipe
To make these amazing fried fish tacos, you'll need to have the following ingredients on hand:
- cod fillets, diced
- whey protein powder
- baking powder
- garlic salt
- chili powder
- cayenne pepper (for a little extra kick)
How to make easy fish tacos
The whey protein, baking powder, salt, chili powder, and cayenne pepper (if using) are whisked together in a medium-sized bowl for the low carb breading. In another bowl, the eggs are beaten.
Next, the cod is diced into bite-sized pieces. Then it's dipped into the dry mixture followed by a quick dip into the beaten eggs. Finally, it's dipped back into the dry mixture. The process is then repeated until all the fish pieces are well coated.
A large skillet is used to fry each piece in hot oil about ¼ to ½ deep. It takes about 3-5 minutes to cook each side of the fish to a golden brown color. When fully cooked, the fish should flake easily.
If you'd prefer, an air-fryer could by used to reduce the amount of oil and make less mess. The fish could probably be baked in the oven as well.
I'd suggest cooking at 350°F in the air fryer for 10-12 minutes and flipping half-way or giving a little shake. In the oven, I'd try either 375°F or 400°F for about ten minutes or until browned.
How to serve fish tacos
The fried breaded fish are best served with homemade keto-friendly tortillas along with Pico de Gallo and a few lime slices. Or try serving them with some cucumber salsa which has less fruit sugar than those made with only tomato. The taco mayo sauce I use for serving burnt broccoli is another great option!
If you don't have any tortillas made, that's perfectly okay. The recipe can be made served without the tortillas and enjoyed as a paleo fish taco bowl. Or, just enjoy them as fish lettuce wraps.
These cod fish tacos are great as a lighter lunch or you can add sides to it for a full dinner. And they are so delicious that even your non-keto friends and family will love the recipe.

I'm wondering if you've included the tortilla & pico in the Nutritional Content? If so, which brand tortillas & pico or recipes?
The tortilla and pico is not included as that can vary depending on amount and specific kind used.
I used almond flour instead of whey protein and the fish turned out crispy and delicious, but the tacos as a whole were missing something. I recommend adding slaw and mayonnaise.
You'd have to make sure your mayo is keto and adjust the nutritional content accordingly.
Fish tacos are one of our favorites so naturally I had to give this keto friendly version a try! They're so tasty! We'll definitely be making them again.
These really are the best fish tacos! Thanks for the recipe 🙂
What is an alternative to the whey protein powder in this recipe?
I'll edit the recipe with subs as almond flour or crushed pork rinds should work as well.
What changes would I need to make in fish tacos if I don’t have whey?
I'd just try using finely ground almond flour or crushed pork rinds.
I love fish tacos and really want to try this recipe. Can something else other than Whey Protein be used? I don't normally buy or use it.
Almond flour or crushed pork rinds should work too.
