Super-Detailed Step-by-Step Instructions for Beginners
Preparation Phase (15 minutes)
- Prepare your workspace:
- Clear your countertop to create plenty of space
- Wash your hands thoroughly with soap and warm water for at least 20 seconds
- Lay out all ingredients and tools before starting
- Place a roll of paper towels within easy reach
- Have a trash can or bowl for scraps nearby
- Check your fish:
- Unwrap catfish fillets and place them on a clean cutting board
- Look for any obvious bones by running your finger gently along the surface
- If you find bones, remove them using clean tweezers (pull in the direction the bone is running)
- Inspect for any dark areas (bloodline) – these can be trimmed away with a knife as they may taste stronger
- Pat each fillet dry on both sides using paper towels (press gently, don’t rub)
- Fish should feel slightly tacky but not wet to the touch
- Measure and prepare the buttermilk soak:
- Take a shallow dish that’s large enough to hold all 4 fillets side by side
- Pour 2 cups of buttermilk into the dish (measure using a liquid measuring cup)
- Add 1 tablespoon of hot sauce (use a measuring spoon, not a regular spoon)
- Whisk together using a fork or small whisk until the hot sauce is fully incorporated
- The mixture should be slightly pinkish and uniform in color
- Soak the catfish:
- Gently place each dried fillet into the buttermilk mixture one at a time
- Make sure each fillet is completely submerged (press down gently if needed)
- If fillets are stacked, rearrange them after 5 minutes so all surfaces contact the buttermilk
- Set a timer for 10 minutes (or longer if you have time – up to 1 hour)
- If soaking longer than 15 minutes, place the dish in the refrigerator covered with plastic wrap
- Prepare the coating mixture:
- While fish is soaking, take a large mixing bowl
- Measure and add 1½ cups yellow cornmeal (use a dry measuring cup, level off with a knife)
- Measure and add ½ cup all-purpose flour
- Add 1 tablespoon garlic powder
- Add 1 tablespoon onion powder
- Add 2 teaspoons paprika
- Add ½ teaspoon cayenne pepper (use less if you don’t like spice)
- Add 1 tablespoon salt
- Add 1 teaspoon black pepper
- Whisk all dry ingredients together using a whisk or fork for at least 30 seconds
- Make sure there are no visible clumps of spices or flour
- The mixture should be a uniform light orange-brown color
- Set up your frying station:
- Place your coating bowl near the buttermilk dish
- Put a large plate or baking sheet nearby for the coated fish
- Set up your draining station: either place a wire rack over a baking sheet, or lay 4-5 layers of paper towels on a large plate
- Position these items in a line from left to right: buttermilk dish, coating bowl, plate for coated fish, stove, draining station
- This creates an efficient workflow
- Prepare for frying:
- Place your heavy-bottomed pan or cast iron skillet on the stovetop
- Clip your candy/deep-fry thermometer to the side of the pan if using
- Make sure the bulb of the thermometer is in the oil but not touching the bottom of the pan
- If you don’t have a thermometer, have a small piece of bread ready to test oil temperature
Cooking Phase (15 minutes)
- Heat the oil:
- Measure 4 cups of vegetable oil and pour it into your pan
- The oil should be about 1 inch deep – enough to come halfway up the sides of the fillets
- IMPORTANT: Never fill the pan more than halfway with oil to prevent dangerous overflow
- Turn heat to medium-high
- Let oil heat gradually – this will take about 5-7 minutes
- Target temperature is 350°F (175°C) on your thermometer
- If you don’t have a thermometer: when oil reaches temperature, a small cube of bread should turn golden brown in about 60 seconds
- Test the oil temperature:
- Watch for slight rippling or shimmering on the oil’s surface
- You may see faint wisps of smoke (but if heavy smoke appears, the oil is too hot)
- If using a thermometer, wait until it reads 350°F (175°C)
- If the temperature goes above 360°F, turn down the heat slightly
- If temperature doesn’t reach 350°F after 7-8 minutes, turn up the heat slightly
- Coat the first batch of catfish:
- Have a clean, dry hand (or use tongs) to remove 1-2 fillets from the buttermilk
- Hold each fillet above the dish for 3-5 seconds to allow excess buttermilk to drip off
- Place the fillet in the cornmeal mixture
- Use your other hand (your “dry hand”) to scoop coating over the top of the fillet
- Gently press the coating onto both sides of the fillet using your dry hand
- Lift the fillet and shake off any loose excess coating
- Place the coated fillet on your clean plate or baking sheet
- Repeat with a second fillet if frying two at once
- TIP FOR BEGINNERS: Use one hand for wet ingredients and one for dry to prevent your fingers from getting coated with a gummy mixture
- Prepare for safe frying:
- Have your tongs and fish turner/spatula within easy reach
- Keep a lid for the pan nearby in case of oil flare-ups
- Make sure children and pets are away from the cooking area
- Have oven mitts or heat-resistant gloves ready
- Start frying:
- Pick up one coated fillet with tongs or a fish turner
- Hold it just above the oil surface
- Gently lower one end into the oil, then slowly lay the rest of the fillet away from you
- BEGINNER SAFETY TIP: Stand back slightly and turn your face away during the first few seconds to avoid any oil splatter
- Repeat with second fillet if frying two at once
- Never drop the fish from height into the oil
- Monitor the frying process:
- The oil will bubble vigorously around the fish – this is normal
- Adjust the heat if needed to maintain 350°F
- If oil bubbles too violently, reduce heat slightly
- If bubbling slows too much, increase heat slightly
- Watch for the edges of the fish to turn golden brown
- This first side will take about 3-4 minutes
- Check for doneness on first side:
- Look for a deep golden-brown color around the edges
- The bubbling will become slightly less vigorous when the first side is done
- Gently lift an edge with your fish turner to peek at the color
- The coating should be evenly golden-brown, not pale or dark brown/black
- Flip the fillets:
- Slide your fish turner or tongs completely under one fillet
- Lift it slightly to drain excess oil for 2-3 seconds
- Carefully turn it over, turning away from you to prevent splatter
- If any coating has come off, do not try to replace it
- Repeat with second fillet if cooking two
- Cook the second side:
- The second side usually cooks slightly faster, about 2-3 minutes
- Watch carefully for even browning
- Adjust heat if needed to maintain oil temperature
- Look for bubbling to slow down slightly as fish becomes done
- Test for doneness:
- Fish should be opaque all the way through, not translucent
- Insert a fork into the thickest part and twist gently – the flesh should flake easily
- If you have an instant-read thermometer, the internal temperature should be 145°F (63°C)
- If unsure, make a small cut in the thickest part – the flesh should be white throughout with no translucent areas
- Remove and drain:
- Slide your fish turner completely under the fillet
- Lift it out of the oil and hold it above the pan for 3-5 seconds to drain excess oil
- Move to your prepared draining station (wire rack or paper towels)
- Place fillets in a single layer, not touching if possible
- TIP: Sprinkle a tiny pinch of salt over each fillet while still hot if desired
- Rest the fried fish:
- Let the fillets rest for 1-2 minutes
- This allows the coating to set and excess oil to drain
- If using paper towels, you can gently pat the top with additional paper towels
- Maintain oil temperature for next batch:
- Check oil temperature – it will have dropped during frying
- Allow it to return to 350°F before adding the next batch
- Skim out any loose pieces of coating with a slotted spoon to prevent burning
- This may take 1-2 minutes
- Coat and fry remaining fillets:
- Repeat steps 10-19 with remaining fillets
- Remember to use your “wet hand” for the buttermilk and your “dry hand” for the coating
- Allow each batch to drain and rest while cooking the next
- Prepare for serving:
- Cut lemon into wedges (quarter the lemon)
- Arrange catfish on a serving platter or individual plates
- Place lemon wedges alongside
- Serve immediately while hot and crispy
- Final oil handling:
- Turn off heat
- Let oil cool completely in the pan (several hours)
- Never pour hot oil down the drain
- Once cool, strain through a fine mesh strainer and either:
- Store in a container for reuse (up to 2-3 times) or
- Dispose according to local guidelines (usually in a sealed container in trash)
Troubleshooting Common Issues
Problem: Coating Falls Off During Frying
Solution:
- Make sure fish is thoroughly patted dry before soaking in buttermilk
- Let excess buttermilk drip off completely before coating
- Press coating firmly onto fish
- Let coated fish rest for 5 minutes before frying
- Ensure oil is at the correct temperature before adding fish
Problem: Fish Is Greasy or Soggy
Solution:
- Check that oil temperature stays at 350°F (175°C)
- Don’t overcrowd the pan (fry only 2 fillets at a time)
- Drain properly on wire rack instead of paper towels
- Make sure coating is not too thick
Problem: Undercooked or Overcooked Fish
Solution:
- Use fillets of even thickness (about ½-inch thick)
- Test for doneness with a fork – fish should flake easily
- Use instant-read thermometer to check internal temperature (145°F/63°C)
- Adjust frying time based on thickness of fillets
Problem: Oil Smoking Before Adding Fish
Solution:
- Oil is too hot – remove from heat immediately
- Let cool slightly before returning to heat
- Reduce heat setting
- If oil has a dark color or burnt smell, it should be discarded and you should start fresh
Problem: Coating Too Pale or Too Dark
Solution:
- Pale coating: oil not hot enough (increase temperature)
- Dark coating but undercooked fish: oil too hot (decrease temperature)
- Adjust cooking time as needed for thickness of fillets

- For larger fires, use a fire extinguisher or call emergency services
- Keep a fire extinguisher in your kitchen
- Never add water to hot oil
- Let oil cool completely before discarding or storing
- Wipe up any oil spills immediately to prevent slips
Food Safety
- Fish must reach internal temperature of 145°F (63°C)
- Do not reuse buttermilk mixture after soaking raw fish
- Wash hands thoroughly:
- Before starting
- After handling raw fish
- After touching face, hair, or other surfaces
- Before handling cooked fish
- Sanitize all surfaces that contacted raw fish
- Keep raw fish refrigerated until ready to use
- Don’t leave fish at room temperature for more than 2 hours (1 hour if above 90°F/32°C)
Pro Tips for Perfect Catfish
- For best results: Let fish come to room temperature for 15-20 minutes before cooking (after soaking)
- Temperature control: A cast iron skillet maintains heat better than aluminum or stainless steel
- Oil life: Strain and reuse oil up to 2-3 times before discarding
- Even cooking: Choose fillets of similar size and thickness
- Less mess: Set up “wet station” and “dry station” on different sides of your workspace
- Extra crunch: For extra-crispy catfish, double-dip by coating with cornmeal, then quickly dipping again in buttermilk, then back in cornmeal
- Extra flavor: Add 1 teaspoon Old Bay seasoning to the cornmeal mixture
- Fresher fish: The fresher the catfish, the less “fishy” it will taste
- Buttermilk tip: Soak overnight in the refrigerator for the most tender, flavorful catfish
- Serving idea: Place on paper towel-lined plate with a few lemon slices for a classic presentation
