    Hi friends!

    Sharing a super easy fajitas recipe with you guys today. These cod fish fajitas are so easy and incredibly delicious!

    If you remember a little while ago, I shared a homemade taco seasoning.

    I’ve been using it nonstop because it adds loads of flavour to dishes. Plus, it’s so much better than any packet seasoning.

    How cool would it be to set up a little garnish station, invite some friends over and make a big batch of fajitas?

    Why We Love These Fish Fajitas

    • They’re made on one sheet pan (for easy cleanup).
    • They come together in about 20 minutes, which makes them awesome for an easy weeknight dinner (or Friday night eats).
    • They’re light and fresh.
    • The recipe can easily be doubled for a crowd.
    • If you don’t have cod fillets on hand, you can sub with another similar fish.
    • They can be customized to taste with your favourite toppings.
    • They taste so good!

    What Type of Seafood Do I Use?

    For this fish fajita recipe, I used cod fillets (boneless and skinless). I had frozen on hand so that’s what I used (of course, I thawed before using).

    Simply cut the cod fillets into roughly equal-sized portions so they cook evenly and equally.

    Don’t have cod on hand or prefer to use another type of seafood? Go for it!

    Other delicious options are:

    • Halibut
    • Haddock
    • Sea Bass
    • Tilapia

    Tip: Frozen cod fillets have a lot of excess moisture when thawed. Not a big deal, just make sure you pat them dry with paper towels before coating with olive oil and seasoning.

    How To Make Fajitas

    This oven baked cod recipe is beyond simple! Full details are in the recipe card below, but here are the basics:

    Grease your sheet pan with a little cooking spray or grease with some cooking oil. Then you simply toss veggies with olive oil and taco seasoning. Do the same for the cod. Place onto the prepared sheet pan and bake.

    Tip: Line one half of a sheet pan with parchment paper and place cod strips on there, just in case it wants to stick. Ain’t nobody got time for that!

    After about 10 to 12 minutes (or until the fish is cooked through, is opaque and flakes easily), it’s ready to come out of the oven!

    Once out, give a generous squeeze of lime and try to get the juice on the food, LOL.

    Then its just a matter of piling the cod and veggies onto tortillas, garnishing (if you like) and serving up the deliciousness!

    What Goes With Fajitas?

    You could enjoy these seafood fajitas all on your own, but if you want to make things more substantial any of these work great!

    • Smoky baked black beans
    • Mexican street corn
    • Rice
    • You fave tortilla chips with homemade guacamole and salsa

    Topping Ideas

    • Sliced avocado or guacamole
    • Sliced chili
    • Diced tomato
    • Chopped cilantro
    • Salsa
    • Hot sauce
    • Sour cream

    Tips for Making This Recipe

    • This recipe makes 6 fajitas but can easily be doubled.
    • Make sure your veggies and seafood are spread out on a large pan. Don’t have a large pan? Use two smaller ones.
    • Use for flour tortillas that are around 7 to 8 inches in diameter.
    • You can warm them or enjoy as is. Here are three easy ways to warm tortillas.
    • No salt was added (because the taco seasoning has salt). However, you can add some salt to taste if you wish.

    Ingredients
     

    • Cooking spray, or olive oil (to grease sheet pan)
    • 3 bell peppers, cut into strips
    • 1 yellow, white or red onion, peeled and sliced
    • 2 tablespoons taco seasoning, divided
    • 2 tablespoons olive oil, divided
    • 1.5 pounds boneless and skinless cod fillets, cut into strips
    • 1 lime, juiced (about 2 tablespoons)
    • 6 flour tortillas, about 7 to 8 inches in diameter and warmed according to package instructions

    Garnish Ideas (optional)

    • Avocado, halved, pitted, peeled and sliced
    • Chili pepper, sliced
    • Tomato, diced
    • Fresh cilantro, chopped
    • Pickled red onion
    • Salsa
    • Hot sauce
    • Sour cream

    Instructions

    • Preheat your oven to 400 degrees Fahrenheit. Spray a large sheet pan with cooking oil or grease with a little olive oil. I then like to line half of the sheet pan with parchment paper for the cod.
      Note: If you want to skip the cooking spray or olive oil, just line the whole pan with parchment paper.
    • Place bell peppers and onion in a bowl and sprinkle with 1 tablespoon of the taco seasoning and 1 tablespoon of the olive oil. Toss to coat. Place on one side of the sheet pan (the side without parchment paper if you are lining just half of the sheet pan).
    • Pat cod strips dry of excess moisture with paper towels, then place the cod strips into a bowl and drizzle with remaining 1 tablespoon of taco seasoning and remaining 1 tablespoon of olive oil. Toss to coat. Spread out onto the other half of the sheet pan.
    • Bake for 10 to 12 minutes or until cod is cooked through, is opaque and flakes easily with a fork (insert the tines of a fork into the thickest part of the fish at an angle and twist gently; it should flake easily).
    • Squeeze fresh lime juice over top.
    • Place cod and veggies on warmed tortillas and garnish to taste (if desired) with any of the garnish ideas. Serve and enjoy!

    Notes

    • This recipe makes 6 fajitas but can easily be doubled.
    • Make sure your veggies and seafood are spread out on a large pan. Don’t have a large pan? Use two smaller ones.
    • Use for flour tortillas that are around 7 to 8 inches in diameter.
    • You can warm them or enjoy as is. 
    • No salt was added (because the taco seasoning has salt). However, you can add some salt to taste if you wish.

      This recipe is right up my alley, Dawn! I love all things fajitas, and I’ve actually been craving them lately. We’ve done fish tacos here quite a bit, but never fish fajitas. This will be a fun recipe to mix up the routine a bit! So much flavor going on here. Yum!!

      While I don’t have any cod in my freezer, I do have some sea bass that I was thinking how would I use. These look great Dawn! Happy Easter!
