Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
2 catfish fillets, thawed
1 egg
2/3 cup cassava flour
1/8 cup coconut flour
1 tbsp. paprika
1 tsp. onion powder
salt and pepper to taste
2 sandwich rolls of choice, sliced in half
1 cup mixed greens, divided
1/2 cup red onions, sliced
2 red bell peppers, diced finely
1/2 cup onion, diced finely
1/2 cup white wine vinegar
1/2 cup red wine vinegar
1 1/2 tsp. red pepper flakes
1/2 tsp. salt
Directions
Start by making the relish. Add the diced red bell peppers, diced onion, white wine vinegar, red wine vinegar, red pepper flakes, and salt to a skillet over high heat. Cook for about 5 minutes.
Continue cooking for another 7 to 8 minutes, stirring occasionally, until most of the liquid has evaporated. Turn off the heat, let it cool slightly, then transfer to a glass dish and refrigerate until chilled.
While the relish chills, preheat your oven to 375°F and line a baking sheet with parchment paper.
In one bowl, whisk the egg. In another bowl, mix together the cassava flour, coconut flour, paprika, onion powder, salt, and pepper.
Dip each catfish fillet into the egg, then coat thoroughly in the flour mixture, pressing gently so it adheres well. Place the coated fillets onto the prepared baking sheet.
Bake for 25 to 30 minutes, or until the fish is crispy and golden brown. Remove from the oven.
To assemble, layer mixed greens on the bottom half of each roll, add the baked catfish, then top with the chilled relish and sliced red onions. Serve immediately.

Variations
Use cornmeal instead of cassava flour for a more traditional Southern-style coating.
Add a spread like mayonnaise, remoulade, or spicy aioli for extra richness.
Swap catfish for tilapia, cod, or another mild white fish.
Toast the sandwich rolls for added crunch and flavor.
Include pickles or shredded cabbage for extra texture.
Adjust the spice level by increasing or reducing red pepper flakes.
Storage/Reheating
Store leftover catfish separately from the bread and toppings in an airtight container in the refrigerator for up to 2 days.
Reheat the catfish in the oven at 350°F for about 10–12 minutes to help restore crispiness. Avoid microwaving, as it can make the coating soggy.
The relish can be stored in the refrigerator for up to 4 days and tastes even better after sitting.
Assemble the sandwich fresh for best texture and flavor.
