Ingredients You'll Need
Here's what you'll need – nothing too fancy, just good ingredients that work together beautifully.
- 4 pieces White Fish Fillets (cod, haddock, or tilapia) (about 6 oz each)
- 1/2 cup All-Purpose Flour
- 1/4 cup Cornstarch
- 1 teaspoon Baking Powder
- 1/2 teaspoon Salt
- 1/4 teaspoon Black Pepper
- 1/4 teaspoon Garlic Powder
- 1/4 teaspoon Onion Powder
- 1/2 cup Club Soda (cold)
- 2 cups Vegetable Oil (for frying)
Step-by-Step Instructions
- 1
Pat the fish fillets dry with paper towels. This is crucial for achieving a crispy coating, as excess moisture will steam the fish instead of allowing it to fry properly. Season the fillets lightly with salt and pepper.

In a medium bowl, whisk together the flour, cornstarch, baking powder, salt, pepper, garlic powder, and onion powder. The cornstarch contributes to the crispiness of the batter, while the baking powder provides lift for a lighter texture. Ensure all dry ingredients are evenly distributed.

Slowly pour the cold club soda into the dry ingredients while whisking constantly. Mix until just combined; a few lumps are okay. Overmixing will develop the gluten in the flour, resulting in a tougher batter. The club soda should be added just before frying to maintain its effervescence.

Heat the vegetable oil in a large, heavy-bottomed skillet or pot over medium-high heat until it reaches 350°F (175°C). Use a thermometer to ensure the oil is at the correct temperature. If the oil is not hot enough, the fish will absorb too much oil and become greasy. If it's too hot, the batter will burn before the fish is cooked through.

Dip each fish fillet into the batter, ensuring it's fully coated. Let the excess batter drip off before carefully placing the fillet into the hot oil. Working in batches prevents overcrowding the pan and lowering the oil temperature, which can lead to soggy fish.

Fry the fish for 2-3 minutes per side, or until golden brown and the fish is cooked through. The batter should puff up and become beautifully crispy. Avoid flipping the fish too frequently, as this can disrupt the batter and prevent it from browning evenly.

Carefully remove the fried fish fillets from the oil using a slotted spoon or spatula. Place them on a wire rack lined with paper towels to drain excess oil. The wire rack allows air to circulate around the fish, preventing the bottom from becoming soggy.

Repeat the process with the remaining fish fillets, ensuring the oil temperature remains consistent. Adjust the heat as needed to maintain the optimal frying temperature. You may need to add more oil if the level drops significantly.

Once all the fish is fried, season immediately with a pinch of salt. This helps the salt adhere to the crispy batter while it's still hot. Serve immediately while the fish is at its crispiest.

Serve hot with your favorite sides, such as french fries, coleslaw, tartar sauce, or lemon wedges. Garnish with fresh parsley or dill for added flavor and visual appeal. The bright acidity of lemon complements the richness of the fried fish perfectly.

How Do I Know It's Ready?
The fish is done when it flakes easily with a fork and the internal temperature reaches 145°F (63°C). The batter should be golden brown and crispy.
Frequently Asked Questions
Yes, sparkling water can be used as a substitute for club soda. However, club soda may provide a slightly better crisp due to the added minerals.
