Place 1/2 cup flour and the cornmeal in a shallow dish. Add 1 teaspoon salt, 1/4 teaspoon ground black pepper, and the Old Bay Seasoning. Whisk until combined.
In a second shallow bowl, whisk the eggs with a splash of water. Season lightly with salt and pepper.
In a third dish, add the other 1/2 cup of flour. Season lightly with salt and pepper.
Dry the 1 1/2 inch catfish pieces with a paper towel. Season lightly with salt and pepper on both sides. Dredge the catfish on both sides in the flour, then the eggs, and finally coat with the cornmeal mixture on both sides. Lay on the wire rack and finish dredging all the fillets.
In a large, heavy-bottomed Dutch oven or cast iron skillet, add just enough oil to cover the bottom in a thin layer. Heat the oil over medium-high heat until shimmering. Important:The oil is ready when you drop some of the cornmeal mix in and it sizzles right away. The oil should not smoke, but it will come close. Adjust the heat as necessary.
Using tongs and working in batches, carefully place catfish nuggets in the bottom, making sure they do not touch. Pan fry for about 2-3 minutes on each side, or until golden brown. (Note: Fish is done when it flakes easily with a fork and is no longer translucent in the middle.) Set the fried nuggets on a plate or pan that's lined with paper towels. Add more oil and adjust the heat in between batches as needed.
Serve immediately with a squeeze of lemon and our Cajun Remoulade SauceTip: To keep catfish warm in between batches, put it on a sheet pan in a 200°F oven.

You can also check by cutting a piece open to ensure the inside is opaque and flakes easily.
