1️⃣ Prepare the fish:

Cut the fish fillets into evenly sized portions. Avoid cutting them too thick to ensure they cook through completely when fried.

2️⃣ Cook the fries:

Place the frozen French fries in the oven or air fryer and cook according to the package instructions.

3️⃣ Make the batter:

In a large bowl, combine the flour, baking powder, milk, onion powder, garlic powder, and salt. Stir until smooth.

4️⃣ Heat the oil:

Heat the oil in a large pot, such as a Dutch oven, until it reaches 350°F (175°C). Use a candy thermometer to monitor the temperature and maintain it consistently.

5️⃣ Coat and fry the fish:

Dip each piece of fish into the batter, ensuring it is fully coated. Carefully place the battered fish into the hot oil. Fry in batches, cooking no more than three pieces at a time to avoid overcrowding.

Fry the fish for 5 minutes, flipping once halfway through, until golden brown and fully cooked.

6️⃣ Drain and season:

Remove the cooked fish using a strainer or slotted spoon, and place it on a wire rack to drain. Immediately season with a pinch of salt.

7️⃣ Serve:

Serve the crispy fish alongside the cooked French fries, lemon wedges, and your favorite dipping sauces, such as tartar sauce or ketchup.
