Crispy Grouper 'zydeco Style' Recipe

Portion & Pat Dry

Rinse grouper fillets under cold water and pat dry thoroughly with paper towels. Trim any thin edges so fillets are uniform in thickness (about 1/2 to 3/4 inch) for even cooking.

Place fillets in a shallow dish. Combine buttermilk, hot sauce, granulated garlic, and 1 tsp kosher salt in a bowl and pour over the fish so fillets are fully coated. Cover and refrigerate for 30–45 minutes (buttermilk gently tenderizes and adds a tangy base).

While fish marinates, build the dry breading: In a wide, shallow dish combine flour, cornmeal, panko, paprika, cayenne, dried thyme, onion powder, black pepper, and 1 tsp kosher salt. Whisk to distribute spices evenly. The panko adds extra crispness; cornmeal gives a coarse crunch—adjust quantities to preference.

Set up a three-step dredge station: 1) Dry seasoned breading (prepared above). 2) In a second shallow bowl whisk together eggs, milk, and Dijon mustard until smooth. 3) Reserve the marinated fillets (let excess buttermilk drip off but do not pat dry).

Heat a heavy skillet (cast-iron preferred) over medium-high heat. Add oil and heat until shimmering and a pinch of flour sizzles on contact (about 350–365°F / 175–185°C if using a thermometer).

Working one fillet at a time, dredge fish first in the dry breading, pressing gently to form an even coating, then dip into the egg wash, letting excess run off, and finally press again into the dry breading for a double-crust coating. Place coated fillets on a wire rack and let rest 5 minutes so coating adheres.

Add butter to the hot skillet and swirl; when it foams add 2 fillets (do not overcrowd). Fry 3–4 minutes per side, spooning hot oil over the tops once or twice, until crust is deep golden brown and internal temperature reaches 135–140°F (fish opaque and flakes easily). Adjust time for thickness (thicker fillets may need 5–6 minutes per side).

Transfer cooked fillets to a wire rack set over a sheet tray to keep crisp. Repeat with remaining fillets, returning oil to temperature between batches. If oil darkens, skim out crumbs; top up with a tablespoon of fresh oil if needed.

Finish by squeezing fresh lemon over the fillets and sprinkling chopped parsley. Serve immediately with the Zydeco Remoulade on the side.

While fish cooks, make the remoulade: In a small bowl whisk together mayonnaise, Creole or whole-grain mustard, pickle relish, chopped capers, hot sauce, Worcestershire sauce, lemon juice, and Cajun seasoning until smooth.

Fold in finely sliced green onion. Taste and adjust seasoning with extra hot sauce, lemon juice, or salt as needed. Chill until ready to serve. The remoulade should be creamy, tangy, and slightly spicy to complement the crispy grouper.
