The inspiration for this incredible sandwich journey began with my sister-in-law, Jamie, who resides in the beautiful Panhandle of Florida. Living in such a prime coastal location, she has access to some of the freshest, most exquisite seafood imaginable. Before visiting her a couple of summers ago, I truly didn’t comprehend the meaning of “fresh seafood.” That trip was an eye-opener, particularly our visit to Joe Patti’s Seafood Market in Pensacola.
Joe Patti’s isn’t just a market; it’s an experience. Situated right on the water, you can literally watch the fishing boats dock, unloading their recent catches straight from the Gulf. The air buzzes with activity, and the sheer variety of seafood is astounding – species I’d never even heard of before. From gleaming snapper to colossal shrimp and exotic local fish, it’s a seafood lover’s paradise. The quality and freshness are unparalleled, and I vividly remember thinking, “This is what seafood is supposed to taste like!”
To this day, I must admit, I harbor a deep, undeniable jealousy of Jamie’s proximity to such culinary treasures. I find myself craving the flavors and the atmosphere of Joe Patti’s on a regular basis. It’s a memory that often sparks new ideas in my kitchen. It was during one of our recent chats that Jamie enthusiastically shared a recipe she had recently tried and absolutely adored: a blackened tilapia sandwich, perfectly complemented by a vibrant cilantro lime mayonnaise. Every element of her description resonated with me – the bold seasoning, the tender fish, and the bright, creamy sauce. Naturally, I knew I had to recreate it.

Crafting the Perfect Blackened Tilapia and Zesty Mayonnaise
The original recipe Jamie mentioned had roots in Paula Deen’s kitchen, but as I delved into the preparation, I found myself diverging slightly to incorporate my own preferred techniques and ingredients. While I absolutely adored Paula Deen’s concept for the Cilantro Lime Mayonnaise – it’s a brilliant pairing for blackened fish – I opted for a different approach when it came to the blackening seasoning itself.
For the quintessential blackened flavor, I turned to a beloved favorite: Chef Paul Prudhomme’s Blackened Redfish Magic. I first stumbled upon this phenomenal seasoning during a trip to St. Thomas, of all places, where I enjoyed the most unforgettable blackened fish sandwich. The deep, smoky, and subtly spicy notes of this blend are simply unparalleled, transforming any white fish into a flavorful masterpiece. It creates a beautiful, dark crust while sealing in the moisture, resulting in incredibly tender and succulent fish.
Blackening is a cooking technique that involves coating fish or meat with a generous amount of spices and then searing it in an extremely hot, heavy cast-iron skillet. The high heat creates a dark, flavorful crust, giving the dish its characteristic “blackened” appearance. Don’t be intimidated by the name; it’s not about burning the fish, but rather about creating a rich, flavorful char that adds depth to every bite. Tilapia is an excellent choice for blackening due to its mild flavor, which allows the spices to shine, and its firm texture, which holds up well to the high heat.
My love for blackening isn’t limited to this sandwich. I frequently use this exact seasoning to prepare other seafood dishes, such as my recipe for Blackened Salmon with Citrus Salsa, where the bold spice is beautifully balanced by the fresh citrus, and in these vibrant Spicy Fish Wraps. It’s a versatile seasoning that consistently delivers incredible results, making it a staple in my pantry.

Perfect Pairings and Serving Suggestions
To accompany these delightful blackened tilapia sandwiches, I opted for some homemade baked red potato chips – a healthier alternative to fried chips that still delivers a satisfying crunch. The earthy flavor of the potatoes provides a wonderful contrast to the spicy fish and creamy mayonnaise. However, the possibilities for side dishes are endless. A classic, creamy coleslaw would also be an absolutely fantastic pairing, offering a refreshing, cool counterpoint to the warmth of the sandwich. That’s definitely on my list for next time!
Other excellent side dish ideas include a crisp green salad with a light vinaigrette, sweet potato fries for a touch of sweetness, or even roasted asparagus or green beans for an extra boost of vegetables. For those who prefer a low-carb meal, serving the blackened tilapia directly over a bed of mixed greens or in large lettuce cups is a delicious and healthy alternative. You can also pair it with a side of steamed broccoli or cauliflower rice. The vibrant flavors of the fish and mayonnaise are adaptable to many different accompaniments.

This Blackened Tilapia Sandwich with Cilantro Lime Mayonnaise is a truly fantastic and flavorful option for any weeknight. It’s quick, healthy, and incredibly satisfying. The spicy, flaky tilapia perfectly balances the creamy, zesty mayonnaise.

Ingredients
- 4 tilapia fillets (fresh or frozen – if frozen, ensure they are fully thawed and patted dry before seasoning)
- Blackened Redfish Magic seasoning (or your favorite blackening blend)
- Non-stick cooking spray or 1-2 tablespoons high-smoke-point oil (like canola or grapeseed oil)
- 4 fresh kaiser rolls (or your preferred sandwich buns)
- 1 cup good quality mayonnaise (homemade or store-bought)
- 1/4 cup freshly chopped cilantro leaves (ensure they are thoroughly washed and dried)
- 1 tablespoon fresh lime juice (from about 1/2 lime)
- Optional garnishes: sliced tomatoes, crisp lettuce, red onion rings, or avocado slices
Instructions
- Prepare the Tilapia: Begin by patting your tilapia fillets thoroughly dry with paper towels. This step is crucial for achieving a good, crispy blackening crust. Sprinkle the blackening seasoning liberally over both sides of each tilapia fillet. Adjust the amount of seasoning based on your personal preference for spice – you can go light or bold!
- Cook the Fish: Heat a heavy-bottomed skillet (a cast-iron skillet works best) over medium-high to high heat. Once hot, spray generously with non-stick cooking spray or add a tablespoon of high-smoke-point oil. Place the seasoned fish fillets into the hot pan, ensuring not to overcrowd the skillet (cook in batches if necessary). Cook for approximately 3-4 minutes per side, or until the fish is opaque, flaky, and has developed a beautiful dark, crusty char. The cooking time may vary slightly depending on the thickness of your fillets.
- Make the Cilantro Lime Mayonnaise: While the fish is cooking, prepare your flavorful mayonnaise. In a small bowl, combine the mayonnaise, freshly chopped cilantro leaves, and fresh lime juice. Stir well until all ingredients are thoroughly mixed and the sauce is creamy. Taste and adjust seasoning if needed. For best flavor, cover the bowl and chill in the refrigerator for at least 15-20 minutes to allow the flavors to meld.
- Assemble and Serve: Lightly toast your kaiser rolls, if desired. Spread a generous amount of the homemade cilantro lime mayonnaise on both halves of each roll. Place a cooked blackened tilapia fillet onto the bottom half of each roll. Add any optional garnishes you prefer, such as slices of fresh tomato, crisp lettuce, or thinly sliced red onion. Top with the other half of the roll and serve immediately with your favorite side dish!
