Last Updated on 23rd April 2022 by

Really good fish tacos can take a lot to put together. They may have numerous ingredients and require the fish to be prepared just right, which is why I’m going to show you how to prepare fish for fish tacos and make this tasty dish from scratch for yourself.

What stops a lot of people from making fish tacos on their own is cooking the fish. Don’t let it intimidate you, though. Simply cutting up the fish and cooking it in oil is really simple and only takes a few minutes.

Keep on reading to learn all the steps for making fish tacos piece by piece.

How to Bake Fish for Fish Tacos

You don’t have to fry up your fish when you’re making fish tacos. If you want a healthier method that uses less oil, you can bake fish filets in the oven instead. Let me share with you a recipe for season, baked fish that you can use in fish tacos.


  • 1 pound of fish fillets
  • 1 tablespoon of lemon juice
  • 3 tablespoons of butter
  • 1/4 teaspoon of salt
  • 1/4 teaspoon of paprika


  1. Preheat the oven to 375 degrees Fahrenheit.
  2. Prepare a baking pan by greasing it lightly.
  3. Place the fish into the pan with the skin side facing down, if cut, and season with all of your ingredients.
  4. Bake the fish for 15-20 minutes, until it is tender and can flake easily with a fork.

Be careful about overbaking the fish, as it can dry out and lose some of its taste.

How to Bake Mahi Mahi for Fish Tacos

Not all fish filets cooked the same, as some will be thicker or denser. Some kinds of fish benefit from different seasonings. How do you cook mahi mahi to use in fish tacos? Try this simple recipe for a flavorful fish filet that’s great for fish tacos.


  • 2 pounds of mahi mahi filets
  • 1/4 teaspoon of garlic salt
  • 1 teaspoon of lemon juice
  • 1/4 cup of chopped white onion
  • 1/4 teaspoon of black pepper
  • 1 cup of mayonnaise
  • Breadcrumbs


  1. Preheat the oven to 425 degrees Fahrenheit.
  2. Prepare the fish by rinsing it off, patting it dry, then placing it into a baking dish.
  3. Season the fish with lemon juice, pepper, and garlic salt.
  4. Mix together chopped onions and mayonnaise and then spread over your fish. Sprinkle breadcrumbs over top of the filets.
  5. Bake for 25 minutes at 425 degrees Fahrenheit.

How to Make Fish Stick Tacos

You could also use fish sticks in your fish tacos. You can simply follow the baking directions on the packaging to prepare the fish sticks. Fish sticks can be prepared in the microwave or the oven, and you can chop them up into smaller, bite-sized pieces before you add them to your fish tacos.

What goes well with fish sticks when making fish tacos? Try combining them with small pieces of ripe avocado, red onion, cilantro, purple cabbage, and jalapeno peppers, topped with a drizzle of creamy Sriracha sauce.

This is probably the simplest and fastest way to make fish tacos from scratch, since the fish sticks are already prepared and just need to be heated.

It’s a great method for how to take a frozen fish and make fish tacos from it in a matter of minutes. Fish sticks can be heated from frozen and do not need to be thawed out first.

How to Make Fish Tacos with Leftover Fish

Fish tacos don’t take much fish, so you can use leftover fish to use in tacos and have plenty to fill them out. Just make up for any deficit with other ingredients, like vegetables, cheese, and sauce.

You may want to season your leftover fish up specifically for the tacos, adding some spicy ingredients like red pepper flakes or chili powder or even a little taco seasoning to them to make them more appropriate for tacos.

How to Freeze Fish Tacos

If you make up fish tacos ahead of time, you can freeze them until you are ready to serve the tacos. Hard shell tacos freeze just as well as soft shell ones. However, it’s not a good idea to freeze lettuce or cabbage, as well as some of the other veggies you might put in fish tacos. Cheese and fish freeze perfectly fine, though.

For the freshest fish tacos, it’s best to freeze just the fish and whatever salsa or sauces you’re going to have with it. All your fish meat and sauces can be put into a freezer safe bag and stored in the freezer for several months, until they’re ready to be used.

Alternatively, you could store the entire fish taco in an airtight container in the fridge for up to two days. Keep in mind how fresh your vegetable ingredients are, because if they’re close to their expiry date already, they may not last the two days in the fridge.

How to Assemble Fish Tacos

If you’ve never made fish tacos before, you might be wondering what goes in them and how to put them together. A lot of the ingredients are up to you and whatever your preferences might be at the time.

There are tons of ways to make fish tacos, but you will usually be working with a few different types of key ingredients. You have your fish, vegetables, cheese, and sauce. You may also make them with rice or beans, but those are not typically a part of fish tacos.

Fish tacos should be assembled with veggies first. The vegetables make up the bulk of the tacos, and then the fish is added on top of that. Any shredded cheese you’re including goes next, and then sauces are added last.

All of that gets wrapped into a folded tortilla shell or hard shell taco. Feel free to make your own variations, using ingredients you’ve handpicked.

Fish tacos can be made from all sorts of things, and sometimes you may just be working from whatever leftovers are in the fridge.
