Crunchy breaded swai is both a fun and comforting food. Swai is a type of catfish that offers a mild, sweet flavor and its flaky flesh contrasts well with a crisp crust. Frying is the most effective way to develop the optimal golden color and significant crunch. The cooking process is relatively straightforward, so the swai will fry in a matter of minutes. Cook it in batches, but don't crowd them in the pan. If you will be cooking a lot at once, keep the finished filets in your oven, turned to its lowest setting, as you make subsequent batches.

Soak the swai in buttermilk in a nonreactive dish for at least 10 minutes or up to 8 hours in the refrigerator. Stir in additional flavoring agents, if desired, such as salt and pepper, a favorite hot sauce, a splash of vinegar, Worcestershire sauce, garlic and onion powder and/or chili pepper powder.

Prepare a breading for the fish filets in a shallow bowl. Combine ingredients such as all-purpose flour, cornmeal, corn flour, panko or other breadcrumbs, salt, pepper and dried herbs and spices.

Pour about 2 inches of peanut oil or another cooking oil with a high enough smoke point for deep-frying into a large heavy-bottomed skillet and heat it to 350 degrees Fahrenheit. Monitor the oil temperature with a deep-fry thermometer.

Dredge the swai filets in the breading and gently brush off the excess. Lay them carefully in the oil, two at a time. Fry them for approximately 2 to 3 minutes per side, until the breading develops a deep golden-brown color and the flesh of the fish is opaque all the way through.

Transfer the cooked swai to a plate lined with a few paper towels, supporting them underneath with a wide-slotted spatula. Let them sit for a few minutes so the paper towels absorb excess oil.

  • Buttermilk
  • Nonreactive dish
  • Flavoring agents
  • Breading ingredients
  • Shallow bowl
  • Peanut or other cooking oil
  • Large skillet
  • Deep-fry thermometer
  • Slotted spatula


  • As an alternative to soaking the swai in buttermilk to get the breading to stick, submerge the fish in beaten egg.
  • To cut back on calories, make "oven-fried" breaded swai. Rather than pan-fry it in a lot of oil, bake it in the top one-third of the oven at 375 F for about 25 minutes, or just until the breading is golden brown and the swai's flesh is opaque all the way through.
  • Thaw frozen swai by storing it in the refrigerator for at least 12 hours.
