Here I used flounder, but you can use any white flaky fish fillet! In the summer when we go fishing and catch black striped bass, this is usually my go-to! More fish recipes you make love, Fish Florentine and Fish Tacos, two of my most popular!

Cajun Spiced Fish

I try to incorporate fish in my diet at least twice a week, to keep it exciting I like to prepare it in different ways. This recipe is perfect for a busy weeknight meal, you can use any white fish such as sole or cod. Serve this with crusty bread, brown rice or quinoa to soak up the delicious sauce.

Variations and Tips

  • Any firm, white boneless fillet would be great, I choose local and ask my fishmonger for the freshest options available. Here I used flounder cod, but halibut, or striped bass would make a great option.
  • When fresh fish is available, wait until the day or day before to buy it before you are going to cook it.
  • If fresh isn’t available, buy frozen instead of previously frozen to control freshness and keep it frozen until you need it.
  • Frozen fish fillets are great to keep on hand in the freezer. You can defrost them overnight in the fridge or pull from from the freezer and put them in an ice bath (in the package if they are individually wrapped or in a sealed Ziploc) for about 30 minutes
  • Swap the fish for scallops or shrimp if you’re not a fan of fish.

  1. I made this for lunch and it was soooo good! I can’t do spicy so I used smoked paprika and the sauce was awesome!

  2. It has been a year since I have made this dish, but I don’t know why! I forgot how delicious and easy it is. Everything about it is amazing!

  3. I made this with Red Snapper. Turned out fabulous. I will definitely be making it again.

  4. I was looking for a recipe with white fish and tomatoes the other day and couldn’t find one that didn’t have all kinds of obscure ingredients. This recipe is perfect. Thank you. It’s exactly what I was looking for. I can’t wait to try it.

  5. Really really good and very easy

  6. Sorry I love all your recipes but this one didn’t work for me at all. 

  7. I made this for a first time for when I had family over. We all absolutely LOVED this dish. This would be a great dish for people that tend to not even like fish. The flavors were amazing! I bought a spicy cajun – and did not think it would have enough flavor so I added it to the fish before putting in pan, but it would not have needed this. We served this over brown rice. The fish just fell apart in the pan before I even got to serve it. DELICIOUS. Thank you!

  8. This is the easiest recipe ever and thr taste is amazing.

    The ingredients were things that I already had on hand and all of the flavors came together so well.

    I’ll be looking for more dishes from your site.

  9. This was soooo good and easy! We used fresh halibut because that’s what was available. Thanks so much for this!

  10. So easy – really, from someone who does not cook. My fiancee and I agreed we would have felt fine spending $30 on this dish from our favorite seafood restaurant.
