What Is the Popeyes Flounder Fish Sandwich?

The Popeyes Flounder Fish Sandwich is a seafood twist on the brand’s famed chicken sandwich. As we mentioned in our previous article, the Popeyes Fish Sandwich typically makes a comeback during the Lenten season (between February and April), and this has proven to be true once again. Its components include:
- Flounder Fillet: A wild-caught flounder fillet, known for its mild and subtly sweet flavor, providing a clean taste without an overpowering fishiness.
- Brioche Bun: A butter-toasted, soft brioche bun that adds a hint of sweetness and complements the savory filling.
- Pickles: Thick-cut, barrel-cured pickles offer a tangy crunch, balancing the richness of the fried fillet.
- Sauce Options:
- Classic: Paired with creamy tartar sauce, enhancing the fish’s flavor.
- Spicy: Features a spicy mayo spread, adding a zesty kick for those seeking extra heat.
This straightforward yet flavorful composition sets it apart from competitors like McDonald’s Filet-O-Fish and Wendy’s Fish Sandwich. The use of flounder, a less common choice in fast-food fish offerings, coupled with Popeyes’ signature Cajun seasoning, delivers a distinctive taste experience.

Popeyes Flounder Fish Sandwich Recipe
If you love the Popeyes Flounder Fish Sandwich but want to enjoy it at home, this copycat recipe brings you the same crispy, flavorful experience. Here’s how you can recreate it:
Ingredients:
- For the Fish:
- 2 wild-caught flounder fillets

- ½ cup cornmeal
- 1 tablespoon Cajun seasoning
- ½ teaspoon salt

- 2 brioche buns
- 4-6 thick-cut pickles
- 2 tablespoons tartar sauce (for classic) or spicy mayo (for spicy)
Instructions:

Marinate the Fish
- Soak the flounder fillets in buttermilk for at least 30 minutes. This helps tenderize the fish and enhances flavor.

Coat the Fish
- Remove the fillets from buttermilk, letting excess drip off, and dredge them in the flour mixture. Press gently to ensure even coating.
Fry to Perfection
- Heat vegetable oil in a deep skillet to 350°F (175°C). Fry fillets for 3-4 minutes per side until golden brown and crispy. Drain on paper towels.


Drain Excess Oil
- A freshly fried golden-brown flounder fillet draining on a wire rack to maintain crispiness.
Brioche Bun Prep
- A toasted brioche bun with a layer of creamy tartar sauce, getting ready for sandwich assembly.


Assemble the Sandwich
- Lightly toast the brioche buns. Spread tartar sauce (classic) or spicy mayo (spicy) on the bottom bun, add pickles, then place the crispy flounder fillet on top. Cover with the top bun and serve hot.
