Ah, fish tacos. Living in San Diego has made me spoiled on fish tacos. I used to eat beer-battered fish tacos once a week, but at over 1,000 calories per meal I rarely get it… unless I’m pregnant. Then I go crazy because, you know, the baby wants it.

But I digress.

I missed eating fish tacos, so I came up with this Keto Low-Carb Fish Tacos recipe that even my kids enjoy. I eat these gluten-free fish tacos with lettuce cups while my kids enjoy it with gluten-free corn tortillas.

These Low-Carb Fish Tacos are Paleo-friendly too and so easy to adapt to your tastes. Switch the spices up, add extra grilled veggies or other yummy extras. They are so easy to make your own but here are some ideas you might like…

Variations – What Else Can I add To These Low-Carb Fish Tacos?

  • Grilled veggies such as zucchini
  • Switch the spices up to your taste
  • Pickled red onions
  • Jalapenos

You can have some fun with the fixings too… like try it with purple cabbage, sour cream, different types of cheese (cotija would be amazing), tomatoes, salsa, and, of course, avocados.

Ingredients for Keto Low-Carb Fish Tacos

How to Make These Low-Carb Fish Tacos

These Low-Carb Fish Tacos are naturally gluten-free because they aren’t battered and fried. They’re grilled in the oven. Just add a few spices like cumin, chili powder, and salt along with olive oil to fresh fish (I prefer wild-caught sole or cod). Cover the fish well with the spices and then bake in the oven.

While the fish is baking, you can get all the fixings ready… like the tomatoes, purple cabbage, lettuce, avocados, cheese, and sour cream. I like to grill gluten-free corn tortillas right on my gas stovetop for my kids who prefer to eat this Low-Carb Fish Tacos with a traditional soft taco.

    This is a spectacular dish! I thought it would be difficult to make when I saw the photo – but even I was able to create the fish tacos and everyone enjoyed them.

    I did not miss the tortillas! I mean, you’re gonna put some kind of lettuce or or cabbage on your tacos anyway, so having that crispness all around the fish filling makes absolute sense! Super simple and quick…just what I need on a weeknight.

    These tacos sound so delicious, great idea to use lettuce instead of tortillas to make them lighter!
