Ingredients for louisiana fried fish
Pantry staples meet Cajun boldness—just 15 ingredients for golden, crispy fried fish.
| Ingredient | Amount | Notes |
|---|---|---|
| White Fish Fillets 🐟 | 1 ½ lb | Catfish, tilapia or cod preferred |
| Medium Yellow Cornmeal 🌽 | 1 cup | Stone-ground preferred for texture |
| All-Purpose Flour 🌾 | ½ cup | For light, crispy batter |
| Dried Buttermilk 🥛 | ¼ cup | Powdered or liquid works |
| Smoked Paprika 🌶️ | 1 tbsp | Key for authentic flavor |
| Cayenne Pepper 🔥 | ½ tsp | Adjust for heat preference |
| Filé Powder 🌿 | 1 tbsp | Ground sassafras leaves |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Vegetable Oil 🫒 | 3 cups | High smoke point preferred |
| Lemon Wedges 🍋 | 2 whole | For serving |
| Mayonnaise 🥫 | ½ cup | For remoulade base |
| Hot Sauce 🌶️ | 2 tbsp | Crystal or Tabasco preferred |
| Capers 🍅 | 1 tbsp | Chopped for remoulade |
| Red Onion 🧅 | ¼ cup | Finely diced for remoulade |
The fish is your canvas, so freshness matters most. Look for fillets with a clean, ocean-like scent and firm texture—catfish or tilapia are classic choices, but cod works too. Pat them bone-dry before dredging; any moisture throws off the crisp. For cornmeal, Bob's Red Mill stone-ground is my go-to—it's coarser than regular cornmeal, which helps create that signature crunch. If you can't find filé powder, substitute 1 tbsp cornstarch, though it won't have the same earthy depth. The oil? Peanut or vegetable oil both work, but avoid olive oil—it burns too easily.
No buttermilk? Mix 1 tbsp vinegar with 0.25 cup milk for a quick swap. Running low on capers? Pickle juice or a dash of Worcestershire sauce adds tang in a pinch. For the remoulade, Duke's or Crystal hot sauce bring that authentic kick—don't skimp. The red onion should be sharp, not sweet; white or yellow onions work too, but red adds that signature color. If you're short on time, pre-chop the onion and capers and store them in the fridge for up to 3 days. The batter mix keeps dry for 1 week in an airtight container.
The remoulade keeps for 5 days in the fridge, but the flavor deepens overnight—make it ahead if possible. For the fish, fry just before serving to maintain that perfect crunch. If you're prepping ahead, assemble the fish with dry batter and refrigerate for up to 4 hours before frying. The oil stays hot for 2-3 batches, but strain it through a fine-mesh sieve after each use to remove excess batter. Store leftover oil in a sealed jar for up to 1 month—great for future frying projects.

Step-by-step instructions for Louisiana fried fish with crispy cornmeal crust
Master this classic Southern technique for perfectly golden, shatteringly crisp fish every time.
Prepare the Cornmeal Batter for Maximum Crisp
In a large bowl, whisk together the 1 cup medium yellow cornmeal, 0.5 cup all-purpose flour, 0.25 cup dried buttermilk, 1 tablespoon smoked paprika, 0.5 teaspoon cayenne pepper, 1 tablespoon filé powder, 1 teaspoon salt, and 0.5 teaspoon ground black pepper. The filé powder is what gives that authentic Louisiana flavor—it's not optional. Mix until completely combined, breaking up any lumps in the dried buttermilk.
Here's the thing—this batter needs to be thick but still pourable. If it looks too dry, whisk in 1 tablespoon of water at a time until you reach a consistency like heavy cream. The goal is a batter that coats the back of a spoon but still flows freely when you tilt the bowl. Let it rest for 5 minutes while you prepare the oil—this allows the buttermilk to fully hydrate the dry ingredients for an extra-crisp crust.
Heat the Oil to the Perfect Frying Temperature
Fill a deep fryer or heavy pot with 3 cups vegetable oil to a depth of 2 inches. Attach a deep-fry thermometer and heat the oil to 360°F. This is critical—if the oil isn't hot enough, your fish will absorb oil instead of developing that golden crust. If it's too hot, the outside will burn before the inside cooks through.
Test the oil's readiness by dropping in a small piece of fish batter. It should sizzle immediately and float to the surface within 30 seconds. If it sinks or doesn't sizzle, your oil needs more time to reach temperature. Keep the oil at 360°F for frying—any higher and you risk burning the crust before the fish cooks through.
Fry the Fish in Batches for Even Cooking
Pat the 1.5 lb white fish fillets completely dry with paper towels—moisture is the enemy of crispiness. Working in batches to avoid overcrowding (which lowers oil temperature), carefully dip each fillet into the batter, letting any excess drip off before gently lowering it into the hot oil. The batter should adhere evenly without dripping excessively.
Fry for 3-4 minutes per side until the crust is deep golden brown and the fish flakes easily when tested with a fork. Don't walk away—fish cooks fast, and the moment the crust reaches that perfect golden hue is when you remove it. Transfer to a wire rack set over a paper towel-lined plate to drain excess oil. The rack keeps the fish crispy while the paper towels catch drips.
Assemble the Spicy Remoulade Dip
While the fish fries, combine the 0.5 cup mayonnaise, 2 tablespoons hot sauce, 1 tablespoon chopped capers, and 0.25 cup finely diced red onion in a bowl. Mix until fully incorporated, then taste and adjust seasoning if needed. The remoulade should be tangy, slightly spicy, and bright—this is what balances the richness of the fried fish.
For extra authenticity, stir in 1 teaspoon of lemon juice from one of the wedges. The acidity cuts through the fat and makes the flavors sing. Cover and let it sit at room temperature while you finish frying the fish. This dip should be served immediately alongside the hot, crispy fish for maximum impact.
Serve with Lemon and Remoulade
Arrange the fried fish on a platter and serve immediately with the 2 whole lemon wedges and the prepared remoulade dip. The lemon isn't just for garnish—it's essential for cutting through the richness of the fried fish and adding freshness to each bite. Encourage your guests to squeeze lemon over their fish as they eat.
This dish is best served while the crust is still crisp and the fish is hot from the fryer. The contrast between the shatteringly crisp cornmeal crust, the tender fish beneath, and the cool, tangy remoulade makes every bite unforgettable. If you're serving more than four people, double the remoulade recipe—it disappears fast!
Pro Tips For Making Louisiana Fried Fish
- PAT THE FISH DRY: Grab paper towels and press hard—this isn’t the time to be gentle. Wet fish steams instead of fries, and you’ll end up with soggy crusts no matter how much cornmeal you use. I learned this the hard way after frying a batch that looked golden but tasted like a soggy biscuit.
- USE TWO CRUSTS: Dip the fish in flour first, then the buttermilk mix, then cornmeal—don’t skip the middle layer. The flour acts as glue, and the buttermilk adds tenderness. I used to skip it, and the crust would crack off like brittle chips. Trust me, the double-dip is worth it.
- FRIED AT 350°F: Too hot, and the outside burns before the inside cooks. Too cool, and you get greasy, undercooked fish. A steady 350°F in small batches (don’t crowd the pan) gives you a crispy crust and flaky fish every time. After burning three batches, I finally figured out the sweet spot.
- REFRIGERATE THE BUTTERMILK MIX: Cold buttermilk makes a thicker, stickier batter that clings better. Mix your flour, dried buttermilk, and spices, then pop it in the fridge for 30 minutes—yes, even if you’re impatient like me. The crust will be smoother and less likely to slide off.
Health benefits of this dish
Lean Protein Power
Louisiana fried fish delivers a lean protein punch with about 25 grams per serving—perfect for a lighter yet satisfying meal. White fish like catfish or tilapia are naturally low in fat while packed with essential amino acids for muscle repair.
The cornmeal crust adds fiber, making this dish more balanced than traditional fried foods. 💪
Rich in Omega-3s
If you choose fatty fish like salmon (though not traditional for this recipe), you’d get a heart-healthy dose of omega-3 fatty acids. Even leaner options like tilapia still provide vitamin B12 and niacin, supporting energy metabolism.
The filé powder in the batter adds a unique earthy note while contributing antioxidants from sassafras.
Balanced with Remoulade
The spicy remoulade dip transforms this dish into a flavorful, nutrient-dense experience. Capers and red onion add vitamin C and antioxidants, while the hot sauce provides a metabolism-boosting kick. The tangy mayo base ensures you’re not drowning in empty calories—just bold, satisfying flavor. 🌶️
Low-Carb Option
Unlike traditional flour-based fried fish, this recipe uses cornmeal as the primary crust ingredient, keeping carbs in check. A single serving contains about 15 grams of carbs, making it a great choice for low-carb or keto diets. The remoulade’s tangy profile also helps curb cravings for heavier sides.
Heart-Healthy Frying
Using vegetable or peanut oil (high in monounsaturated fats) keeps cholesterol in check compared to butter-based frying methods. The key is maintaining the oil at 360°F—this ensures the fish cooks quickly, minimizing oil absorption. Serve with a side of steamed greens to complete the heart-healthy plate. 💛
Cultural Comfort Food
Beyond nutrition, this dish offers the emotional benefits of comfort food—rich in tradition and tied to Louisiana’s Cajun heritage. The combination of crispy crust, spicy kick, and tangy remoulade creates a satisfying, mood-boosting experience.

Frequently asked questions
What type of fish works best for this Louisiana fried fish recipe?
Catfish, tilapia, and cod are the most popular choices for authentic Louisiana fried fish. These white fish fillets stay tender while developing that signature crispy crust. Avoid oily fish like salmon or mackerel—they can make the crust greasy. Pat the fillets completely dry before dredging to ensure maximum crispiness.
Can I make the cornmeal batter ahead of time?
Mix the dry ingredients and store them in an airtight container for up to 1 week. When ready to fry, simply whisk in the dried buttermilk and water to reach the right consistency. The batter will keep its texture better if you let it rest for 5 minutes before using—this helps the cornmeal absorb moisture for an extra-crisp crust.
How do I keep the fried fish from getting soggy?
Moisture is the enemy of crispiness! Pat the fish fillets completely dry with paper towels before dredging, and fry them immediately after battering. Transfer the fried fish to a wire rack (not a plate) to allow air circulation while draining. Never stack them—they’ll steam and lose their crunch. For extra insurance, keep the oil at 360°F and fry in small batches.
What can I serve with Louisiana fried fish?
Classic pairings include creamy hushpuppies, tangy coleslaw, or steamed greens. For a complete Louisiana spread, add pickled okra or jalapeño peppers. The spicy remoulade in this recipe works perfectly as a dip, but you could also serve it with buttery cornbread or a crisp green salad. Don’t forget lemon wedges—they’re essential for cutting through the richness!
Can I bake this fried fish instead of deep-frying?
While baking won’t give you that authentic crispy crust, you can achieve a lighter version by using an oven-safe skillet. Heat 1/4 inch of oil in a cast-iron skillet, coat the fish in batter, then bake at 425°F for 12-15 minutes, flipping halfway. For extra crunch, broil for 1-2 minutes at the end. The texture will be different, but it’s a healthier alternative that still delivers bold flavors.
