Ingredients for middendorf's thin fried catfish
Four delicate fillets, one crispy crust, and a tangy sauce that captures Middendorf's legendary Southern technique.
| Ingredient | Amount | Notes |
|---|---|---|
| Catfish Fillets 🐟 | 4 whole | Thin-cut, skin-on preferred |
| All-Purpose Flour 🌾 | ¾ cup | For dredging fillets |
| Fine Yellow Cornmeal 🌽 | ¾ cup | Stone-ground for texture |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tbsp | For seasoning batter |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Vegetable Oil 🫒 | 3 cups | For frying at 360°F |
| Mayonnaise 🥛 | ½ cup | Full-fat preferred |
| Fresh Lemon Juice 🍋 | 2 tbsp | Freshly squeezed |
| Dill Pickle Relish 🥒 | 2 tbsp | Finely chopped |
| Fresh Dill Weeds 🌿 | 2 tbsp | Chopped finely |
| Capers 🍅 | 1 tbsp | Chopped for tang |
| Hot Sauce 🔥 | 1 tsp | Optional for heat |
| Paper Towels 🧻 | 1 package | For draining fillets |
| Lemon Wedges 🍋 | 4 whole | For serving |
The catfish fillets are the foundation—look for thin-cut, skin-on pieces at specialty seafood markets or well-stocked grocery stores like Whole Foods or H-E-B. The skin provides structural integrity for the crispy crust, so avoid boneless, skinless cuts. For cornmeal, stone-ground varieties create that signature texture; brands like Maison de Mère or Bob's Red Mill deliver consistent results. Pre-season your cornmeal mixture with Diamond Crystal kosher salt—it dissolves more evenly than table salt, ensuring balanced flavor without saltiness overwhelming the delicate fish.
No fresh dill? Dried dill at one-third the amount works in a pinch, though fresh delivers that bright, herby punch. Substituting vegetable oil for frying? Peanut oil is ideal for its high smoke point, but vegetable oil works if maintained at 360°F consistently. For the tartar sauce, Hellmann's or Duke's mayonnaise provide the right texture, while Heinz relish offers that classic tang. The capers can be omitted entirely if you prefer a milder sauce—just increase lemon juice to 3 tbsp for brightness. For extra crunch, add 1 tbsp crushed cornflakes to the batter mixture.
Maintain oil temperature at 360°F using a deep-fry thermometer—this is non-negotiable for achieving that signature crunch. Drain fried fillets on a rack over a baking sheet to prevent sogginess, not paper towels. The tartar sauce keeps for 3 days in an airtight container in the refrigerator, though it's best served immediately with the crispy fillets. For meal prep, fry the catfish ahead and reheat in a 375°F oven for 5-7 minutes to restore crispiness. Serve with lemon wedges for an authentic Middendorf touch.

Step-by-step instructions for Middendorf's thin fried catfish
Mastering the crispy cornmeal crust requires precision and timing—here's how to achieve perfect results.
Prepare the Catfish and Batter Mixture
Pat the 4 whole catfish fillets completely dry using the package of paper towels. Remove any remaining pin bones with tweezers, working carefully to avoid tearing the delicate flesh. The skin should remain intact for optimal crispiness.
In a shallow dish, whisk together the 0.75 cup all-purpose flour, 0.75 cup fine yellow cornmeal, 1.5 tablespoons diamond crystal kosher salt, and 0.5 teaspoon ground black pepper until evenly combined. This dry mixture forms the foundation of your crispy crust. I recommend using a wire whisk to break up any cornmeal lumps completely.
Create the Tartar Sauce
In a small bowl, combine the 0.5 cup mayonnaise, 2 tablespoons fresh lemon juice, 2 tablespoons finely chopped fresh dill weeds, 2 tablespoons dill pickle relish, 1 tablespoon chopped capers, and 1 teaspoon hot sauce. Mix thoroughly until all ingredients are fully incorporated and the sauce reaches a smooth, vibrant consistency.
Let the tartar sauce rest at room temperature for 10 minutes before serving. This allows the flavors to meld together more completely. The sauce should be thick enough to cling to the catfish but still spreadable. If it's too thick, add a teaspoon of water to reach your desired consistency.
Fry the Catfish to Crispy Perfection
Heat 3 cups vegetable oil in a deep fryer or heavy pot to 360°F, using a thermometer for accuracy. The oil should shimmer gently when a small piece of bread is dropped in—this indicates proper heat. Working with one fillet at a time, dredge each thoroughly in the batter mixture, pressing gently to adhere.
Carefully lower the battered fillets into the hot oil using tongs. Fry for 3-4 minutes per side until the crust achieves a deep golden brown color and the fish flakes easily when tested with a fork. Avoid overcrowding the fryer, as this will lower the oil temperature and result in greasy rather than crispy catfish.
Drain and Serve Immediately
Transfer the fried catfish to a wire rack set over a baking sheet lined with paper towels. Let drain for 2-3 minutes to remove excess oil while maintaining crispness. The crust should remain rigid rather than collapsing—this indicates proper frying technique.
Serve the catfish immediately with the prepared tartar sauce and the 4 whole lemon wedges on the side. The lemon juice brightens the rich flavors while cutting through the oiliness. For best results, serve with a side of coleslaw or steamed vegetables to complement the crispy exterior and tender interior.
Pro Tips For Making Middendorf'S Thin Fried Catfish
- PAT THE FILLETS DRY: I learned this the hard way—wet catfish means soggy crust. After patting each fillet with paper towels, let them sit uncovered on a wire rack for 10 minutes. The extra effort guarantees that crispy cornmeal coating everyone remembers.
- MIX FLOUR AND CORNMEAL: Skip the separate dredging—toss the flour and cornmeal together in a shallow dish with 1 teaspoon salt and a grind of pepper. The cornmeal sticks better this way, and you avoid the messy two-step process. (Yes, even if you're impatient like me.)
- FRIED IN BATCHES: Crowding the pan drops the oil temperature fast, and your catfish turns greasy instead of golden. Work in single layers with 30 seconds between batches—your future self will thank you for not rushing this.
- REST BEFORE SERVING: Does it look weird? Yes. Does it work? Every single time. Transfer fried fillets to a wire rack and let them sit 2–3 minutes. The crust sets properly, and the fish stays moist—no more flaky, greasy disappointment.
Flavor customization for this dish
Spicy Cajun Kick
For those who love heat, add 1 tbsp Cajun seasoning (like Tony Chachere's) to the cornmeal batter mixture. This transforms your tartar sauce into a fiery Southern fusion—perfect for spice lovers.
I recommend adding ½ tsp cayenne pepper directly to the tartar sauce for an extra kick. Serve with extra hot sauce on the side for customizable heat levels. 🌶️
Smoky BBQ Twist
Swap the tartar sauce for a smoky BBQ glaze by mixing ½ cup Kansas City-style BBQ sauce (like Sweet Baby Ray's) with 1 tbsp apple cider vinegar and 1 tsp smoked paprika.
Brush this over the fried catfish after frying for a sweet-smoky contrast. Pair with pickled red onions for tangy crunch and a side of cornbread for a full Southern spread.
Creamy Lemon-Herb Variation
Transform the tartar sauce into a lighter, brighter version by replacing the mayonnaise with ½ cup Greek yogurt (like Fage 5%) and adding 1 tbsp fresh chives and 1 tbsp chopped parsley.
This keeps the crispy texture but adds a refreshing, herby brightness. Perfect for those who prefer a lighter sauce but still want that signature tang. 🍋
Sweet & Spicy Glaze
Create a sweet-spicy glaze by mixing ¼ cup honey with 2 tbsp sriracha and 1 tbsp soy sauce. Brush this over the fried catfish after frying and broil for 1-2 minutes to caramelize.
The glaze adds a glossy finish while balancing the crispy crust with sweet and spicy notes. Garnish with sesame seeds for an Asian-inspired twist.
Herb-Infused Butter Dip
For a richer alternative, melt ½ cup unsalted butter with 2 tbsp chopped fresh parsley, 1 tbsp chopped dill, and 1 tsp lemon zest. Serve this warm herb butter as a dip alongside the crispy catfish.
The buttery richness complements the cornmeal crust beautifully, especially when paired with steamed asparagus or roasted Brussels sprouts.
Citrusy Mango Salsa
For a refreshing tropical twist, top the fried catfish with a mango salsa made from 1 cup diced mango, ¼ cup red onion, 2 tbsp chopped cilantro, 1 tbsp lime juice, and ½ tsp jalapeño.
The sweetness of the mango contrasts perfectly with the crispy crust, while the lime juice keeps the dish bright and zesty. 🌟

Frequently asked questions
Why does Middendorf's recipe use cornmeal instead of flour for the crust?
The cornmeal creates that signature crispy-yet-light texture that's impossible to achieve with flour alone. The fine yellow cornmeal absorbs less oil than flour, resulting in a crunchier exterior while keeping the fish tender inside. The stone-ground variety adds subtle graininess that contrasts beautifully with the smooth tartar sauce.
Can I use frozen catfish fillets for this recipe?
Yes, but thaw them completely first in the refrigerator for 24 hours to prevent excess moisture that can make the crust soggy. Pat the fillets extra dry with paper towels before dredging—the skin should be completely moisture-free for that perfect crisp. Never thaw at room temperature, as this promotes bacterial growth.
What's the secret to keeping the crust crispy after frying?
Drain the fried catfish on a wire rack (not paper towels) for 2-3 minutes to evaporate excess oil while maintaining crispness. Serve immediately with the tartar sauce—waiting even 5 minutes will cause the crust to soften. For reheating, broil for 1-2 minutes at 400°F to restore crunch.
How do I adjust the recipe for thicker catfish fillets?
For fillets over 1-inch thick, reduce frying time to 2-3 minutes per side and check for doneness at 165°F internal temperature. The cornmeal crust will still crisp up even with thicker cuts—just avoid overcooking. For extra insurance, pat the thickest parts with additional cornmeal mixture before frying.
What's the best way to store leftover fried catfish?
Store in an airtight container for up to 2 days in the refrigerator. Reheat in a 375°F oven for 5-7 minutes on a wire rack to restore crispiness. For longer storage, freeze for up to 1 month—thaw overnight in the fridge before reheating. The tartar sauce keeps separately for 3 days in the fridge.
