How To Make The Best Grilled Blackened Fish Sandwich

Looking for a flavorful meal that will be ready fast, but is also delicious too? Then, you have to try my blackened fish sandwich recipe! My family loves fish, especially around the summertime when there is plenty of fishing and grilling going on. And, living in Florida, the weather is summer-like almost year round, so I like to whip up this dish pretty often. There is something special about blackened fish on the grill. The smokiness combined with a kick of flavor is already delicious.

Combine it with some of my homemade mango and jalapeño slaw and serve it on a hamburger bun, and you’ll have your family thinking you slaved away cooking all day. It can be our little secret just how quickly you made it though!

Seasoning Suggestions for Fish Sandwiches

While I used blackening seasoning for this sandwich, there are lots of other flavor combinations you could use as well. Some of my favorites are:

  • Garlic, salt and pepper
  • Lemon juice and butter
  • Soy sauce with dijon mustard, and if you like heat like I do, throw in some chili flakes
  • Lemon juice and garlic
  • Lime with basil
  • Paprika and garlic

There are so many flavors that work well with fish!

Is Blackened Fish Spicy?

It can be. That is the simplest answer to the question of whether or not blackening seasoning is spicy. Chilli Pepper Madness calls blackening seasoning “spicy and piquant.” It marries the flavors of creole and cajun seasonings.

My best advice if you don’t care for spicy foods is either to sprinkle less on your fish, or opt for a different seasoning altogether. The good news is, the slaw cools down some of the heat, and you can remove the jalapeño from the homemade slaw too if you want to cool the dish down further.

What Type of Fish is Best for the Blackened Fish Sandwich?

I used cod, but grouper and mahi would also be delish. You definitely want a more mild fish with this dish. In other words, one that isn’t as fishy. Ask your grocery store for their recommendations, and don’t be afraid to try the local catch of the season.

What Exactly is Blackened Fish?

It’s fish that is cooked with blackening seasoning. The difference between it and charred is it’s not burnt, or well done. What gives it the smoky flavor is the seasoning itself.

What if You Don’t Have a Grill? Can I Still Make a Blackened Fish Sandwich?

Yes! In a pinch you could pan fry your fish on your stovetop. It won’t be as smoky and flavorful as on the grill, but it gets the job done!

How to Make a Blackened Fish Sandwich:

  1. To get started, season both sides of your fresh fish with blackening seasoning
  2. Preheat your grill to about 350 degrees. This will give your seasoning some time to marinade into the fish
  3. Grill fish until cooked throughout, it will be flaky 
  4. While the fish is grilling, make your mango and jalapeño slaw (recipe below). Who doesn’t like a little island flair?!?
  5. Grab a hamburger bun, and place a nice-sized filet of your blackened fish on one side – I used King’s Hawaiian Sweet Hamburger Buns. They are uniquely soft and have a fluffy texture and just a touch of sweetness, making them perfect for my Blackened Fish Sandwich and all our grilling.
  6. Then, top with your fresh slaw.

Why top a blackened fish sandwich with coleslaw at all, you ask? Topping with slaw adds some sweetness to the spicy seasonings of the fish. And, it’s just really tasty!

Pair it with a glass of Pinot Grigio, and a side dish of sweet potato fries for a truly filling lunch or dinner.

How to Make Mango and Jalapeño Slaw

  1. Dice your mango and jalapeño (leave seeds in for extra heat)
  2. Pour 1/2 bag of shredded coleslaw into a medium size bowl. You can use fresh sliced cabbage if you prefer, but it’s much easier to use bagged slaw on those busy nights when the kiddos have baseball practice or karate!
  3. Add jalapeño, mango, mayo, olive oil, red wine vinegar, and sugar to the coleslaw
  4. Stir well, and either use immediately, or chill and serve later
