How to Fry Battered Cod and Onion Rings
Prepare the Cod
Pat your cod pieces dry with paper towels and sprinkle a pinch of salt and pepper over each piece. This helps the seasoning stick and ensures a crisp exterior.
Mix Dry Ingredients for Cod Batter
Grab a large bowl and toss in these ingredients:
Whisk everything together until well combined.
Prepare Wet Ingredients
In another bowl, crack 1 large egg and beat it lightly. Pour in 1 cup of cold club soda and mix well.
Create Cod Batter
Pour your wet ingredients into the dry mixture. Stir gently – a few lumps are totally fine. Your batter should look smooth but not overworked.
Slice and Prep Onions
Cut 2 large yellow onions into 1/2-inch thick rings. Separate the rings carefully so they stay intact.
Batter the Onion Rings
Mix your dry onion ring ingredients in a bowl:
Dip each onion ring first in the flour mixture, then into 1 cup cold milk, then back into the flour mixture.
Heat the Oil
Pour vegetable oil into a deep pot until it’s about 3 inches deep. Heat to exactly 350F using a cooking thermometer.
Fry the Cod
Dip each cod piece into the batter, let excess drip off, then carefully lower into the hot oil. Fry for 3-4 minutes per side until golden brown. The internal temperature should reach 145F.
Fry the Onion Rings
Gently place battered onion rings into the oil. Fry 2-3 minutes per side until they turn a beautiful golden color.
Make Dipping Sauce
Whisk together in a small bowl:
Drain and Serve
Place fried cod and onion rings on a paper towel-lined rack to drain excess oil. Serve immediately with the dipping sauce on the side.

Crispy Battered Cod with Onion Rings FAQs
Can I use a different type of fish?
Absolutely! Cod works great, but halibut, tilapia, or haddock are excellent alternatives with similar textures and mild flavors.
What if I don’t have club soda for the batter?
Regular cold water works perfectly fine. The key is using a cold, carbonated liquid to help create a light, crispy texture.
Do I need a deep fryer to make this recipe?
No way! A heavy-bottomed pot and a reliable cooking thermometer can achieve the same crispy results right on your stovetop.
Can I make the batter ahead of time?
The batter is best when fresh, so prepare it right before frying. Letting it sit too long can make the coating less crispy and deflate the bubbles.
Is there a gluten-free option for this recipe?
Swap regular flour with a gluten-free all-purpose flour blend. The cornstarch already helps create that perfect crispy exterior.
How do I know the oil is the right temperature?
Use a cooking thermometer to check that it’s exactly 350F. If you don’t have one, drop a small piece of bread into the oil – it should sizzle and brown within 60 seconds.
