Step-by-Step Instructions
Step 1: Mix the slaw and let it get lively
In a large bowl, combine the shredded green cabbage, shredded red cabbage, scallions, and dill.
In a small bowl, whisk together the lemon zest, lemon juice, mayonnaise, apple cider vinegar, sugar, kosher salt, and black pepper until smooth. Pour over the cabbage and toss thoroughly.
Refrigerate for at least 10 minutes while you prep the fish. (This short rest helps the cabbage soften just enough and makes the flavors pop.)
Step 2: Stir up the quick tangy sauce
In a small bowl, whisk together the mayonnaise, Dijon mustard, lemon juice, dill, grated garlic, kosher salt, black pepper, and hot sauce (if using).
Cover and refrigerate until serving time. The sauce thickens slightly as it sits.
Step 3: Soak the catfish for tenderness and flavor
In a shallow dish, whisk the buttermilk, hot sauce, and kosher salt.
Add the catfish fillets and turn to coat. Let soak for 10 minutes at room temperature while you prepare the dredge.
Step 4: Build the cornmeal crust and coat the fish
In a second shallow dish, combine the cornmeal, flour, kosher salt, paprika, garlic powder, onion powder, black pepper, and cayenne.
Lift one fillet from the buttermilk, letting excess drip off for a few seconds. Press it firmly into the cornmeal mixture, coating all sides. Repeat with remaining fillets.
Place the coated fillets on a wire rack or a parchment-lined sheet pan and let them rest for 5 minutes. This helps the coating hydrate and cling, which means less falling off in the oil.
Step 5: Heat the oil to the right temperature
Set a wire rack over a sheet pan (or line a plate with paper towels) for draining. If you want to keep batches warm, preheat the oven to 200°F (93°C) and place the rack-and-pan in the oven.
In a 12-inch cast-iron skillet or heavy-bottomed skillet, add enough oil to reach 1 inch depth (typically 3 to 4 cups, depending on the pan). Heat over medium-high until the oil reaches 350°F (177°C).
If you don’t have a thermometer, test with a pinch of dredge: it should sizzle immediately and steadily (not slowly, not violently).
Step 6: Fry until crisp, golden, and flaky
Carefully lower 2 fillets into the oil (don’t crowd the pan). Fry for 3 to 4 minutes per side, turning once, until deep golden brown and the fish flakes easily.
For accuracy, check the thickest part with an instant-read thermometer: the fish should reach 145°F (63°C).
Transfer to the rack to drain. If frying in batches, return the oil to 350°F (177°C) before adding the next batch.
Step 7: Season, plate, and serve like a farm-kitchen supper
While the fish is still hot, sprinkle very lightly with an extra pinch of kosher salt (optional, but it makes the crust taste more “alive”).
Serve each portion with a generous mound of lemon-herb slaw, a spoonful of quick tangy sauce, and lemon wedges for squeezing right at the table.
Pro Tips
- Use fine cornmeal for a tighter, crispier crust: Coarse cornmeal can be tasty, but fine cornmeal fries up more evenly and clings better to catfish.
- Keep the oil at 350°F (177°C): Too cool and the crust soaks up oil; too hot and the coating browns before the fish cooks through.
- Rest the breaded fish for 5 minutes: This quick rest is a small step that makes a big difference in coating adhesion.
- Drain on a rack, not paper towels (if possible): A rack keeps the crust crisp by preventing steam from getting trapped underneath.
- Don’t over-stir the slaw: Toss until coated, then let it sit; overworking can make cabbage weep and turn watery.
Variations
- Spicy Cajun-style: Add 1 teaspoon Cajun seasoning to the cornmeal crust and increase cayenne to 1/2 teaspoon.
- Extra-crunchy double dip: After the first dredge, dip back into the buttermilk briefly, then dredge again. Rest 5 minutes before frying.
- Pickle-bright sauce: Add 1 tablespoon finely chopped dill pickles (or 2 teaspoons pickle brine) to the tangy sauce for a sharper bite.
Storage & Make-Ahead
Best day-of: Fried catfish is crispiest right after cooking.
Refrigerate: Store leftover fish in an airtight container for up to 2 days. Store slaw separately for up to 2 days (it will soften as it sits). Store sauce for up to 5 days.
Reheat: Reheat fish on a wire rack over a sheet pan in a 425°F (218°C) oven for 8 to 10 minutes, until hot and re-crisped. (Avoid the microwave if you want the crust to stay crunchy.)
Make-ahead: Mix the sauce up to 3 days ahead. Shred the cabbage and store it dry, covered, up to 1 day ahead; dress the slaw 10–30 minutes before serving for the freshest crunch.
