The first time I had jerk fish I wasn't sure what to expect. I thought all those bold spices would drown out the delicate flavor of the fish — but it did the opposite. It amplified it. Like any great dish it brought out the best in every bite.
That memory stuck and now it's become one of my favorite ways to make grilled fish tacos — especially when paired with a cool bright mango cucumber salsa that balances the jerk heat perfectly.
Simple. Packed with flavor. Perfect for weeknights, cookouts, or whenever you're craving something bold and fresh.
Why This Works
Lucky Cajun What A Jerk is built on real Scotch bonnet and fresh ground allspice — the two ingredients that make jerk actually taste like jerk instead of just hot. The one hour rest after seasoning allows the fresh ground spices to penetrate the fish before it hits the grill.
Barramundi is the ideal fish for this recipe — firm enough to hold up on a grill without falling apart, mild enough to let the jerk seasoning carry the flavor, and buttery enough to stay juicy through the cook. Grouper, mahi mahi, and salmon all work with the same method.
The mango cucumber salsa isn't just a topping — it's the counterbalance. Cool, bright, and slightly sweet with a pinch of Lucky Cajun Voodoo for a subtle heat underneath. Every bite of jerk fish with a spoonful of that salsa is the whole point.
Ingredients
For the Jerk Fish:
- 16 oz barramundi fillets or firm fish like salmon, grouper, or mahi mahi
- 2 teaspoons Lucky Cajun What A Jerk seasoning
- 2 tablespoons avocado oil or any high-heat neutral oil
For the Mango Cucumber Salsa:
- 1 ripe mango, diced
- ½ burpless cucumber, medium dice
- ½ small onion, diced
- ¼ cup chopped cilantro — or substitute basil or mint
- Zest and juice of 1 lime
- 1 teaspoon Lucky Cajun Voodoo seasoning
For the Tacos:
- 4 to 6 flour tortillas, taco-size
- A little oil for brushing
Instructions
1. Season the Fish
Rub barramundi fillets with Lucky Cajun What A Jerk and oil, coating evenly. Let sit for at least 1 hour. This rest allows the fresh ground seasoning to penetrate the fish before grilling — seasoning that goes straight from the bottle to the grill sits on the surface and falls off during the cook.
2. Fire Up the Grill
Get the grill hot — really hot. Make sure the grates are clean and well-oiled before the fish goes on. A properly preheated, oiled grill is what gives you that perfect sear and clean release. Fish that sticks usually means the grill wasn't hot enough or wasn't oiled properly.
3. Make the Mango Cucumber Salsa
Toss diced mango, cucumber, onion, and cilantro with lime zest, lime juice, and Lucky Cajun Voodoo. Mix gently. Chill until ready to serve. This salsa gets better the longer it sits — make it first and let it rest while the fish marinates.
4. Grill the Fish
Grill for 3 to 4 minutes per side depending on thickness. You want char in spots and easy flaking — those are your two signals the fish is ready. Jerk heat on the outside, juicy on the inside. Don't move it before it releases naturally.
5. Grill the Tortillas
Brush tortillas lightly with oil and grill 15 to 20 seconds per side. This keeps them from sticking and adds texture and a slight char that pairs with the jerk seasoning.
6. Assemble
Flake the grilled fish and pile into warm tortillas. Top generously with mango cucumber salsa. Serve immediately.
Variations With Other Lucky Cajun Blends
Spicier version: Swap What A Jerk for Lucky Cajun Total Jerk for the same tropical jerk profile pushed further with scorpion pepper heat that builds with every bite.
Datil version: Use Lucky Cajun Fiery Datil on the fish instead of What A Jerk for a fruity citrusy heat that pairs naturally with the mango salsa. The Datil and mango flavor profiles are made for each other.
Blackened version: Replace What A Jerk with Lucky Cajun Black Label and cook in a cast iron pan instead of on the grill for a classic blackened fish taco with a darker more intense crust.
Salt-free version: Use Lucky Cajun Salt-Free Cajun on the fish for a lower sodium build without losing the fresh ground depth that makes this taco seasoning actually taste like something.
FAQ
What is the best fish for grilled fish tacos?
Firm fish that holds up on the grill without falling apart. Barramundi, grouper, mahi mahi, and salmon all work well. Delicate fish like tilapia or flounder tend to fall apart over direct grill heat — save those for pan-searing.
How do you keep fish from sticking to the grill?
Clean grates, high heat, and well-oiled grates before the fish goes on. Let the fish release naturally before flipping — if it's pulling back it's not ready. Fish that sticks almost always means the grill wasn't properly preheated or oiled.
How long should you marinate fish in jerk seasoning?
At least 1 hour. The fresh ground Scotch bonnet and allspice in What A Jerk need time to penetrate the surface of the fish. A longer marinate builds deeper flavor but anything under 30 minutes mostly sits on the surface and falls off during the cook.
What is the best Cajun seasoning for fish tacos?
A fresh ground sugar free Cajun seasoning without fillers that blooms immediately on contact with a hot grill. Lucky Cajun What A Jerk is built for this — real Scotch bonnet heat and allspice depth that amplifies the natural flavor of the fish instead of covering it up.
What does barramundi taste like?
Barramundi is a firm, mild, buttery white fish with a clean flavor and low fishiness. It holds up well on the grill, flakes cleanly, and takes seasoning beautifully. It's one of the most underrated fish for grilled tacos.
Can I use corn tortillas instead of flour?
Yes. Corn tortillas are more traditional for fish tacos and hold up well when grilled briefly. They tear more easily than flour so handle them gently and double them up if needed.
Why add Voodoo seasoning to the mango salsa?
A pinch of Lucky Cajun Voodoo in the salsa adds a subtle habanero heat underneath the sweetness of the mango. It gives the salsa depth without turning it into a hot sauce — and it ties the salsa back to the Cajun flavor profile of the fish.
How do you season Cajun shrimp the same way for tacos?
Season shrimp generously with What A Jerk right before cooking over high heat. Shrimp cook in under 2 minutes per side — pull the moment they curl and turn pink. Build the same taco with the mango cucumber salsa. Jerk shrimp tacos with mango salsa is one of the best variations of this recipe.
Can I make the mango salsa ahead of time?
Yes — and it's better if you do. Make it at least 30 minutes before serving so the lime juice and Voodoo seasoning have time to bloom into the mango and cucumber. Up to 4 hours ahead is ideal. After that the cucumber starts to release water and the texture changes.
Is this recipe gluten free?
The fish and salsa are naturally gluten free. Use corn tortillas instead of flour to make the complete taco gluten free. Every Lucky Cajun blend is 100% gluten free, sugar free, and filler free.
Why Lucky Cajun
Jerk seasoning only tastes like jerk when the allspice and scotch bonnet oils are still active. Most store-bought jerk blends have been sitting in a warehouse for 12 to 18 months by the time they reach your kitchen — the oils are gone and what's left is salt and color.
Lucky Cajun What A Jerk is ground fresh every week and shipped with a Born-On Date on every bag. The difference is immediate when it hits a hot grill.
