Spicy. Bold. Not your average po'boy.
This sandwich is the best of both worlds — a classic shrimp po'boy meets the island heat of jerk seasoning. No frying needed, no overcooking allowed. Just big flavor, juicy shrimp, and a garlicky mayo that ties everything together.
The key is knowing how to season Cajun shrimp properly and cooking them fast enough that they stay juicy instead of turning rubbery. This method does both.
Why This Works
Lucky Cajun What A Jerk is built on real Scotch bonnet and fresh ground allspice — the two ingredients that make jerk seasoning actually taste like jerk instead of just hot. The seasoning goes on the shrimp with oil before cooking so it blooms immediately when it hits the hot pan.
20 to 25 seconds per side. That's it. Shrimp cook faster than almost any other protein and the window between perfectly cooked and rubbery is narrow. High heat, fast cook, pull immediately.
The garlic mayo is built to match the heat. Extra virgin olive oil gives it richness and body. Lemon juice adds brightness. Black Label adds a subtle Cajun depth underneath the garlic. It's not just mayo — it's a sauce.
Soft untoasted French bread is essential. A toasted bun creates friction and pulls the shrimp out when you bite. Soft fresh bread compresses slightly and holds everything together for a cleaner bite.
Ingredients
For the Shrimp:
- 8 shrimp, 30 to 40 count per pound
- 1 tbsp Lucky Cajun What A Jerk seasoning
- 1 tbsp neutral oil
For the Garlic Mayo:
- 1 cup mayo
- ¼ cup extra virgin olive oil
- Juice of ½ lemon
- 1 large garlic clove, finely chopped
- ½ tsp Lucky Cajun Black Label seasoning
For the Sandwich:
- 1 soft French loaf, 7 to 8 inches, cut lengthwise but not all the way through — keep the hinge intact
- 2 medium lettuce leaves, cut into ribbons
- A few slices of fresh tomato
- A few slices of red onion
Instructions
1. Season the Shrimp
In a bowl toss shrimp with Lucky Cajun What A Jerk and 1 tablespoon of neutral oil. Make sure each shrimp is well coated. The oil helps the seasoning bloom on contact with the hot pan and prevents sticking.
2. Make the Garlic Mayo
Combine mayo, extra virgin olive oil, lemon juice, finely chopped garlic, and Lucky Cajun Black Label in a food processor or bowl. Blend or whisk until creamy and smooth. Taste and adjust — more lemon for brightness, more Black Label for depth.
3. Cook the Shrimp
Heat a pan over medium-high until hot. Sear shrimp for 20 to 25 seconds per side — just until cooked through and slightly charred on the edges. Pull immediately. Overcooked shrimp are rubbery and no amount of sauce fixes that.
4. Assemble
Slather garlic mayo generously on both sides of the French bread. Add lettuce ribbons, tomato slices, and red onion. Top with hot jerk shrimp. Fold gently and serve immediately.
This sandwich does not wait.
Shrimp Count Explained
The count number tells you how many shrimp are in a pound. 30 to 40 count means approximately 30 to 40 shrimp per pound — a medium to large size that works well for sandwiches. Larger shrimp take slightly longer to cook. Smaller shrimp cook faster. Adjust your timing accordingly but the 20 to 25 second rule is your baseline.
Bread Tip
Find a local bakery for the freshest French loaf possible. Most grocery stores now have in-house bakeries so great bread is more accessible than it used to be. Soft, fresh, and barely split — that's your perfect base. Do not toast it. Soft bread is the move here.
Variations With Other Lucky Cajun Blends
Smoky version: Swap What A Jerk for Lucky Cajun Voodoo for a smoky habanero kick that pairs well with the garlic mayo.
Sweet heat version: Use Lucky Cajun Fiery Datil for fruity citrusy heat with a peppery punch. The Datil and garlic mayo combination is unexpectedly great.
Caribbean version: Add a spoonful of mango chutney to the shrimp before assembling for a touch of sweetness that plays off the jerk seasoning.
Extra spicy: Drizzle Datil-infused hot honey over the finished sandwich. Sweet heat over jerk shrimp is one of the best flavor combinations you can put on a po'boy.
FAQ
How do you season Cajun shrimp properly?
Season generously with fresh ground Cajun seasoning and neutral oil right before cooking over high heat. The oil helps the seasoning bloom on contact with the hot pan and prevents sticking. Cook 20 to 25 seconds per side and pull the moment they curl and turn pink. Fresh ground seasoning builds flavor instantly — processed blends with fillers produce flat results no matter how much you use.
What is the best Cajun seasoning for shrimp po'boy?
A fresh ground sugar free Cajun seasoning without fillers gives you the most authentic flavor. 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. For a more classic Cajun profile Lucky Cajun Black Label or Voodoo both work well.
Why cook shrimp for only 20 to 25 seconds per side?
Shrimp cook faster than almost any other protein. The window between perfectly cooked and rubbery is extremely narrow. High heat and fast cooking produces juicy shrimp with slightly charred edges. Longer cooking tightens the muscle fibers and pushes all the moisture out.
Why use untoasted bread for a shrimp po'boy?
Soft fresh bread compresses slightly when you bite and holds everything together. Toasted bread creates friction that pulls the shrimp and toppings out when you bite into the sandwich. Classic New Orleans style po'boys are always built on soft untoasted French bread.
What does What A Jerk seasoning taste like on shrimp?
Warm, aromatic, slightly sweet, and building to a Scotch bonnet heat that doesn't overwhelm. The allspice adds a complexity that generic hot seasoning can't replicate. Fresh ground means the oils are still active when it hits the pan — you smell it bloom immediately.
Can I use frozen shrimp for this recipe?
Yes. Thaw completely and pat very dry before seasoning. Excess moisture prevents proper searing and produces steamed shrimp instead of charred shrimp.
What is a shrimp po'boy?
A po'boy is a classic New Orleans sandwich served on soft French bread. The shrimp version typically features fried shrimp with lettuce, tomato, and remoulade. This version uses jerk-seasoned seared shrimp instead of fried for a faster, bolder, and more versatile build.
What oil works best for searing shrimp?
A neutral oil with a high smoke point — canola, avocado oil, or vegetable oil. Avoid olive oil for searing since it burns at the high temperatures needed to properly char shrimp in under a minute.
Can I make the garlic mayo ahead of time?
Yes. It keeps refrigerated for up to 5 days and improves as the garlic flavor develops overnight. Make it the day before for the best results.
Is Lucky Cajun What A Jerk sugar free?
Yes. Every Lucky Cajun blend is 100% sugar free, filler free, and gluten free — unlike most commercial jerk seasonings which use sugar as one of their primary ingredients.
Why Lucky Cajun
Shrimp cook in under a minute. The seasoning needs to be alive when it hits the pan to build any flavor in that window. Fresh ground What A Jerk with volatile oils still active blooms immediately on contact with high heat. Processed blends that have been sitting in a warehouse for months produce flat results no matter how fast you cook.
Every Lucky Cajun bag ships with a Born-On Date so you know the seasoning is still working when it matters.
