Born from Southern fish-fry culture (think Mississippi Delta and St. Louis plates), this combo slaps because it’s all contrast: shatter-crisp, cornmeal-crusted catfish alongside twirlable spaghetti in a slightly sweet, garlicky tomato sauce with a whisper of heat. The cornmeal crunch + tender, flaky fish + bright, tangy-sweet pasta hits every craving at once, salty, savory, a little sweet, totally satisfying, and it all comes together fast enough for a weeknight.
Ingredients (serves 4)
Catfish
- 4 catfish fillets (6–8 oz each), patted dry
- 1 cup buttermilk
- 1 Tbsp hot sauce (optional)
- 1 cup fine yellow cornmeal
- ½ cup all-purpose flour
- 1½ tsp kosher salt, divided
- 1 tsp paprika
- ½ tsp garlic powder
- ½ tsp black pepper
- ¼ tsp cayenne (optional)
- Neutral oil for frying (about 1½–2 cups)
Spaghetti & Sauce
- 12 oz spaghetti
- 2 Tbsp olive oil
- 1 small onion, finely chopped
- ½ green bell pepper, finely chopped (classic)
- 2 garlic cloves, minced
- 1 can (28 oz) crushed tomatoes
- 1 Tbsp tomato paste
- 1–2 tsp sugar (to taste; gives that signature sweet edge)
- 1 tsp Italian seasoning (or ½ tsp dried oregano + ½ tsp dried basil)
- ½ tsp red-pepper flakes (to taste)
- 1 tsp Worcestershire sauce
- 1 tsp kosher salt + black pepper to taste
- Fresh parsley, chopped (garnish)
Equipment
- Cast-iron or heavy skillet (for frying) + wire rack on a sheet pan
- Large pot for pasta
- Instant-read thermometer (helpful)
Timings
- Prep: 15 minutes
- Cook: 30 minutes
- Total: ~45 minutes
Instructions
- Quick soak the fish (5 min): In a shallow dish, whisk buttermilk with hot sauce. Add catfish; turn to coat while you start the sauce.
- Start the sauce (10 min): Heat olive oil in a saucepan over medium. Sauté onion and bell pepper 5–6 minutes until soft. Add garlic 30 seconds. Stir in crushed tomatoes, tomato paste, sugar, Italian seasoning, red-pepper flakes, Worcestershire, salt and pepper. Simmer gently, uncovered, 12–15 minutes, stirring occasionally.
- Boil pasta: Salt a large pot of water; cook spaghetti to al dente. Reserve ½ cup pasta water; drain. Toss spaghetti with a ladle of sauce; add splashes of pasta water for silky coating. Keep warm; serve with extra sauce.
- Dredge the fish: In a bowl, mix cornmeal, flour, 1 tsp salt, paprika, garlic powder, black pepper, cayenne. Lift fillets from buttermilk, let excess drip, then coat thoroughly in the cornmeal mixture. Set on a rack 5 minutes (helps the crust stick).
- Fry: Heat ½-inch oil to 350°F / 175°C in a cast-iron skillet. Fry catfish 3–4 minutes per side (thinner pieces may need less) until deep golden and flaky (internal temp about 145°F / 63°C). Transfer to rack; sprinkle with the remaining ½ tsp salt.
- Plate: Twirl spaghetti into bowls, spoon on extra sauce, and serve with a hot, crispy catfish fillet on the side. Scatter parsley.
Watch for the battering and oil-temp tips — great for learning the double-dip technique.
Tips & Swaps
- That signature flavor: Don’t skip a little sugar in the sauce—it’s classic for this pairing and balances acidity.
- Keep it crisp: Let dredged fish rest 5–10 minutes before frying, and drain on a rack (not paper towels) so the bottom stays crunchy.
- Air-fryer option: Brush fillets with oil; air-fry at 400°F / 200°C for 10–12 minutes, flipping once, until golden and flaky.
- Baked option: Place on an oiled rack over a sheet pan; bake at 425°F / 220°C for 12–15 minutes.
- Heat level: Add extra red-pepper flakes to the sauce or a dash of hot sauce over the finished fish.
- Make it lighter: Use 8 oz spaghetti and add sautéed mushrooms or zucchini to the sauce.

Can I use other firm white fish instead of catfish?
Yes — try cod, pollock or haddock; adjust frying time for thickness. -
How do I make this gluten-free?
Use a 1:1 gluten-free flour blend and cornmeal labeled gluten-free; test oil temps carefully as crust color will change slightly. -
Can I bake or air-fry the catfish instead of frying?
Yes — brush fillets with oil and air-fry 400°F for 10–12 min, flipping once; or bake on a rack at 425°F for 12–15 min. -
Can I make the sauce ahead?
Yes — the spaghetti sauce stores in the fridge up to 4 days and tastes even better next day. -
How should I reheat leftovers so the fish stays crisp?
Reheat the fish on a wire rack in a 375°F oven for 6–8 minutes until crisp — avoid microwaving. - Is there a lighter option or portion swap? Use 8 oz spaghetti and add roasted veg to the sauce (zucchini, mushrooms) to increase veg and lower carb per serving.
