What is Popeyes Flounder Fish Sandwich
The Popeyes Flounder Fish Sandwich is a seafood twist on everything you love about Popeyes. You get a wild-caught flounder fillet that’s flaky, tender, and lightly seasoned — just enough to let the fish’s natural flavor shine without being overpowering. It’s filed into a soft, buttery brioche bun that gives a hint of sweetness and makes every bite feel balanced and satisfying.
To round it out, Popeyes adds thick-cut, barrel-cured pickles for a tangy crunch and gives you two sauce options: classic tartar for a creamy touch or spicy mayo if you like a little heat. This combination makes the popeyes flounder sandwich stand out from other fast-food fish sandwiches, delivering that perfect mix of flavor, texture, and Cajun flair that keeps you coming back for more.
How to Make a Popeyes Flounder Fish Sandwich at Home
1. Prep the Fish
Start by soaking your Alaska flounder fillets in buttermilk for a bit. This makes the fish tender and flavorful — it’s the little trick that gives you that soft, tasty bite every time.
2. Mix the Coating
In a bowl, combine flour, cornmeal, and your favorite seasonings, like a bit of Cajun spice. This mix will give the fish that golden, crispy crust that makes the sandwich so irresistible.
3. Coat the Fillets
Take the fillets out of the buttermilk, shake off the extra, and press them into the flour mixture. Make sure each fillet is coated evenly so it fries up perfectly.
4. Fry to Golden Perfection
Heat some oil in a pan until it’s hot. Fry the fillets for a few minutes on each side until they’re golden, crispy, and smelling amazing. Let them drain on a paper towel or wire rack to keep that crunch.
5. Toast the Buns
While the fish is frying, lightly toast your brioche buns. Warm buns make the sandwich taste even better and hold everything together nicely.
6. Assemble Your Sandwich
Spread tartar sauce or spicy mayo on the bottom bun, add pickles, then place the crispy fish on top. Cover with the top bun and enjoy it hot — just like you’d get it at Popeyes!
Pro Tip: This sandwich usually makes a seasonal return during Lent, so if you’re craving it anytime else, this homemade version is the perfect way to enjoy it all year round.
