Fish Tacos – Easy, simple, delicious, crispy fish tacos recipe with a low carb tzatziki fish taco sauce. Perfect dinner idea for Taco Tuesday!
Tacos = life. Do you agree? If you said yes, you're going to love this recipe for the most deliciously crispy fish tacos with the most deliciously creamy tzatziki fish taco sauce ever!
We grilled trout fillets to use in our tacos. However, you can use any white, flaky fish you want for this fish tacos recipe.
You can also cook the fish however you choose, though grilling is definitely my favorite way to eat fish. Except, of course, when we make salmon into the most delicious salmon patties; they are definitely a family favorite.
I'll share a few alternative options for how to cook fish below.
Not a fan of fish? No problem! Try our Chicken Tacos or Ground Beef Tacos.
Choose the right fish for fish tacos and cook it!
While we used trout, you can use any white, flaky fish. Food and Wine has a great article on how to choose the right fish for tacos.
Once you've chosen the fish you want to use, you'll need to cook it. We highly recommend grilling on a charcoal grill or gas grill to give your fish a smoky, slightly blackened flavor.
But if you don't want to grill or don't have access to a grill, you can certainly bake the fish or even fry the fish. I'm pretty sure you can even cook fish in your Instant Pot, though you'd definitely want to check pressure cooking times and settings.
Gather your ingredients for this fish tacos recipe:
- Grilled fish (or cooked however you choose)
- Corn tortillas
- Bacon grease or canola oil
- Lettuce
- Tomatoes
- Monterey Jack cheese
- Cheddar cheese
- Green onions
- Cilantro (optional, we did not add this)
- Tzatziki fish taco sauce or sour cream
How to make taco shells for crispy fish tacos:
To make your own crispy taco shells (they remind me of a Taco Bell Chalupa shell)…
- Heat about a tablespoon of bacon grease in a skillet; let it melt and heat up.
- Add a corn tortilla to the skillet, letting it cook on one side.
- Use tongs to turn the tortilla and let the other side cook.
- Finally, remove the tortilla from the skillet and let drain on a paper towel or paper bag for maybe 30 seconds or so.
- Fold into a taco shape and place in either a taco holder or the bottom side of a muffin pan.
And that’s it, you’ve made your own taco shells. They’re so good!
Tips for how to make grilled fish tacos:
First, grill the fish; or cook it however you choose.
Prep all your fresh ingredients. Wash and chop the lettuce, tomatoes, and green onions. Also, shred the cheese.
Fry up a batch of corn tortillas to form taco shells. You can use bacon grease or oil.
Once the fish is fully cooked, taco shells are done, and fresh ingredients are prepped, you’re ready to start the process of layering.
You can layer ingredients in any order you want (I layer them a bit differently in the video and photos from what I describe here), but I prefer to add the fish into the taco shell first, then the cheese (it gets all melty on the warm meat), and go from there.
Add a layer of lettuce.
Then add a layer of tomatoes.
Now add the cheese, green onions, and whatever else your heart desires.
Don’t forget a dollop of tzatziki sauce (though I love adding a good layer of fish taco sauce or sour cream before I even add the meat; that way I have the sauce in every single bite).
And that’s it. Tacos are the easiest thing to make on a busy weeknight!

Kitchen tools you may need to make fish tacos:
Charcoal Grill or Gas Grill – We love using our charcoal grill.
Grilling Spatula – for turning the fish and carefully removing it from the grill.
Iron Skillet – We’re avid users of cast iron cookware. We even take our favorite iron skillet camping with us.
Tongs – They’ll be needed for flipping the corn tortillas in the skillet.
Taco Holder – Ok, so you don’t technically NEED this, but it sure does come in handy. I just use the bottom side of my muffin pan.
Cutting Board and Knife – You’ll use this for way more than just one recipe. We use ours just about every time we step foot in the kitchen.
