Ingredients You’ll Need
Simple ingredients come together effortlessly to build a sandwich that is far greater than the sum of its parts. Each element has been chosen to contribute distinct flavors, textures, and that classic New Orleans spirit that makes this dish so vibrant and memorable.
- Grouper fillets: fresh or thawed, firm and flaky fish that holds up beautifully to blackening.
- Blackened seasoning blend: a mix of paprika, cayenne, garlic powder, and herbs that creates that signature spicy crust.
- Creole sauce: tangy and slightly spicy, made with mayonnaise, ketchup, and Creole seasoning, adding creamy zest.
- Fresh sandwich buns: choose sturdy brioche or potato rolls to hold all the juicy goodness without falling apart.
- Lettuce leaves and tomato slices: for crunch, freshness, and a pop of color.
- Butter or oil: to cook the grouper perfectly and achieve that beautifully charred exterior.
How to Make Blackened Grouper Sandwich with Creole Sauce
Step 1: Prepare the Blackened Seasoning
Mix your paprika, cayenne pepper, garlic powder, onion powder, dried thyme, oregano, salt, and black pepper in a small bowl. This blend will coat your grouper and pack the sandwich with spicy, smoky flavor. The balance of heat and herbs is essential—don’t skip this step!
Step 2: Season the Grouper Fillets
Pat the grouper fillets dry with paper towels, then rub each side generously with the blackened seasoning. Press the seasoning into the fish so it adheres well. This seasoning crust is the soul of the sandwich, giving that irresistible dark and crusty texture and punch of spice.
Step 3: Cook the Grouper
Heat a skillet or cast-iron pan over medium-high heat and add a tablespoon of oil or butter. Once hot, cook the seasoned grouper fillets for about 3-4 minutes per side, or until they develop a blackened crust and the fish flakes easily with a fork. It’s crucial not to overcrowd the pan for the best sear and caramelization.
Step 4: Make the Creole Sauce
While the grouper cooks, whisk together mayonnaise, ketchup, a splash of lemon juice, Creole seasoning, and a dash of hot sauce if you like it spicier. This creamy sauce will bring zesty depth and a little heat that perfectly balances the smoky fish.
Step 5: Assemble Your Blackened Grouper Sandwich with Creole Sauce
Lightly toast your buns if you like a bit of crunch. Spread a generous layer of Creole sauce on both top and bottom buns. Place the succulent blackened grouper fillet on the bottom bun, then top with fresh lettuce and slices of juicy tomato. Cap it with the top bun and get ready to take a big, satisfying bite!

Garnishes
Fresh garnishes like crisp lettuce and ripe tomato slices add a lovely contrast to the spiced fish and creamy sauce. Sometimes a few pickle slices or thin red onion rings can add an extra layer of flavor that really pops against the smooth, smoky grouper.
Side Dishes
Classic sides like Cajun fries, coleslaw, or even a simple side salad with a tangy vinaigrette complement the sandwich beautifully. The sides should echo the fresh or spicy notes without overwhelming the star of the show—the Blackened Grouper Sandwich with Creole Sauce.
Creative Ways to Present
Try serving the sandwich open-faced on a plate garnished with lemon wedges and a sprinkle of freshly chopped parsley for a stunning presentation. You can also turn this sandwich into sliders for a party appetizer or use artisanal bread to elevate its rustic charm further.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftover cooked grouper or sauce, store the fish in an airtight container in the refrigerator for up to 2 days. The sauce keeps well for about 3-4 days when refrigerated, so you can enjoy little flavor boosts on other meals.
Freezing
Freezing the cooked grouper is possible but not ideal, as the texture may become a bit watery after thawing. If you do freeze it, wrap tightly and freeze for up to a month. Thaw overnight in the refrigerator before reheating gently.
Reheating
Reheat leftover grouper in a skillet over low heat to preserve the crust without drying it out. Avoid microwaving if possible, as it can make the fish rubbery. Toast the buns fresh when ready to serve again for the best experience.
FAQs
Can I use other types of fish for this sandwich?
Absolutely! While grouper is ideal for its texture and mild flavor, you can substitute catfish, mahi-mahi, or snapper. Just ensure the fish is firm enough to hold together when blackened.
Is the Creole sauce spicy?
The Creole sauce has a gentle kick but can easily be adjusted. Add more hot sauce or cayenne if you love heat, or tone it down by reducing the seasoning for milder tastes.
How can I make the sandwich healthier?
Try using whole grain buns or lettuce wraps as a lower-carb option. You can also swap the mayonnaise-based sauce for Greek yogurt mixed with Creole spices to reduce calories without losing flavor.
What if I don’t have Creole seasoning?
You can mix your own by combining paprika, garlic powder, onion powder, cayenne, oregano, thyme, salt, and pepper. This DIY blend will match store-bought Creole seasoning well in flavor.
Can I prepare parts of this dish in advance?
Yes! The Creole sauce can be made a day ahead and stored in the fridge. The dry blackened seasoning mix also keeps well, making the actual sandwich assembly quick and easy.

Ingredients
Guacamole Ingredients
- 3 ripe avocados
- 1 Roma tomato, seeded and finely diced
- 1/2 medium white onion, finely diced
- 1/2 cup cilantro, finely chopped
- 4 tbsp lime juice
- 1 jalapeno pepper, seeded and finely chopped
- 1/2 tsp kosher salt
- 1/4 tsp black pepper
Instructions
- Prepare the Avocados: Cut the avocados in half lengthwise and remove the pits carefully. Using a spoon, scoop out the flesh into a medium-sized bowl with a flat bottom. Use a potato masher or fork to mash the avocados until you reach a chunky consistency, leaving some texture.
- Add Lime Juice: Squeeze fresh lime juice over the mashed avocados immediately. This not only adds flavor but also helps prevent the avocado from browning while you prepare the other ingredients.
- Mix in Vegetables and Seasoning: Add the finely diced tomato, white onion, jalapeno pepper, and chopped cilantro to the bowl. Season the mixture with kosher salt and freshly ground black pepper. Gently stir everything together until just combined to retain the texture and freshness.
- Serve: Serve the guacamole immediately with tortilla chips, or use as a topping for your favorite Mexican dishes.
Notes
- For extra heat, include the jalapeno seeds or add more jalapeno according to taste.
- To keep guacamole bright green longer, cover tightly with plastic wrap pressed directly on the surface to minimize air exposure.
- If you like a smoother texture, mash the avocados more thoroughly.
- Store leftovers in an airtight container in the refrigerator for up to 1 day for best freshness.
