Ingredients For Easy Fish Tacos

  • Usually, white fish fillets are used to make tacos because they have a mild flavor. For these tacos, I used Tilapia, red cabbage and carrot slaw, and a few other simple ingredients that will give you the best tacos you’ve ever tasted.

Ingredients For Fish Tacos Sauce

  • A flavorful sauce can really take a simple taco and turn it into something out of this world. With this sauce, you get the citrusy flavors and creamy texture that fish tacos are known for. Key ingredients include broth, dijon mustard, lime juice and zest, heavy whipping cream, and chili powder. You can make this sauce ahead of time and store it in the refrigerator in an airtight container for up to three days.

How To Make The Best Fish Tacos

  • Place fish filets in a baking dish; drizzle with olive oil and sprinkle with salt and pepper.
  • Bake the filets for about 12-15 minutes, or until the fish flakes easily with a fork.
  • Meanwhile, make the fish sauce.
  • Then, heat the tortillas on the stove using a clean, warm frying pan. Be sure to flip the tortilla to warm both sides.
  • Next, you’ll start to assemble your tacos by adding the cooked fish to the warmed tortillas, followed by the red cabbage slaw. Then, you’ll slather the sauce over your fish and dig in.

Frequently Asked Questions

What Is The Best Fish For Fish Tacos

While we love tilapia, any mild white fish fillets work perfectly in this recipe. Cod, halibut, or mahi-mahi are excellent alternatives.

Corn Tortillas Or Flour Tortillas?

I’ve experimented with all tortillas for my fish tacos, but ultimately, the choice is entirely up to you. I, for one, always find myself drawn to charred flour tortillas. For a gluten-free alternative, replace flour tortillas with corn tortillas. For a low-carb version, cauliflower tortillas are a suitable substitution.

Topping Ideas For Tacos

While the fish is baking, I like to get started with preparing my toppings. So many fresh toppings go well with fish tacos! My favorites are bold flavors without too much spice, like guacamole, diced mango, chopped fresh cilantro, roasted corn, pico de gallo, and a sprinkle of cheese, please!

      Tips For Successful Tacos

      • Freshness Counts: The freshness of your ingredients matters significantly in a dish as simple as fish tacos. Use fresh fish, lime juice, and cilantro for the tastiest results.
      • Spice it Up: Don’t be shy to experiment with spices. Chili powder, cumin, and even a dash of smoked paprika can add a depth of flavor to your fish.
      • Getting Crunchy: The addition of slaw or fresh shredded cabbage can add a crunch and a refreshing contrast to the soft tortilla.
      • Make Ahead: You can prepare the fish and the sauce ahead of time. This makes assembling the tacos quick and easy, especially for get-togethers or weekday dinners.
      • Heat the Tortillas: Don’t forget to warm up your tortillas before serving. It makes them pliable and enhances their flavor. You can do this on the stove or even a few seconds in the microwave.
      • The Right Sauce: The creamy, zesty sauce in this recipe brings all the elements together. Remember to taste and adjust your sauce to suit your preferences. Add more lime juice for extra tang, or increase the chili powder for a spicier kick.
