Ingredients for Crispy Fish Fillets with Fries
Fish and Batter
- 4 white fish fillets (cod or haddock)
- 1 cup all-purpose flour
- 1/2 cup cornstarch
- 1 teaspoon baking powder
- 1 teaspoon paprika
- 1/2 teaspoon garlic powder
- Salt and pepper to taste
- 1 cup cold sparkling water
- Vegetable oil for frying
Fries
- 3 large potatoes, cut into fries
- Salt to taste
Tartar Sauce
- 1/2 cup mayonnaise
- 1 tablespoon lemon juice
- 1 tablespoon pickles, finely chopped
- 1 teaspoon mustard
Ingredient Notes
- Fish options: Cod and haddock are ideal because they are mild and flaky. You can also use tilapia or pollock if needed.
- Cornstarch: This helps create a lighter, crispier coating compared to flour alone.
- Sparkling water: The bubbles make the batter airy, which results in a delicate crunch.
- Healthier swap: Replace mayonnaise with Greek yogurt for a lighter tartar sauce.
- Oil choice: Use neutral oils like sunflower or canola for best frying results.
Step-by-Step Instructions
Step 1 – Prepare the Fish
Pat the fish fillets dry with paper towels. Lightly season them with salt and let them rest for about 10 minutes. This helps remove excess moisture and improves the texture when frying.
Step 2 – Make the Batter
In a mixing bowl, combine flour, cornstarch, baking powder, paprika, garlic powder, salt, and pepper. Slowly whisk in cold sparkling water until the batter becomes smooth and slightly thick. Avoid overmixing to keep the batter light.
Step 3 – Heat the Oil
Pour vegetable oil into a deep pan and heat it to 180°C (350°F). Maintaining the correct temperature is key to achieving crispy, non-greasy fish.
Step 4 – Coat and Fry the Fish
Dip each fish fillet into the batter, letting any excess drip off. Carefully place the fillets into the hot oil. Fry for 5–7 minutes until golden brown and crispy. Avoid overcrowding the pan.
Step 5 – Drain the Fish
Remove the fish from the oil and place on paper towels to absorb excess oil. This keeps the coating crisp.
Step 6 – Fry the Fries
Add the cut potatoes to the hot oil and fry until golden and crispy. Remove and season immediately with salt.
Step 7 – Prepare the Tartar Sauce
In a small bowl, mix mayonnaise, lemon juice, chopped pickles, and mustard until smooth and creamy.
Step 8 – Serve
Serve the crispy fish hot with fries on the side and a generous portion of tangy tartar sauce for dipping.
Pro Tips for Success
- Keep ingredients cold: Cold batter creates a better contrast with hot oil, resulting in crispier fish.
- Don’t overcrowd the pan: Fry in batches to maintain oil temperature.
- Use a thermometer: Consistent oil temperature prevents soggy coating.
- Double fry fries: For extra crispiness, fry potatoes twice—once at a lower temp, then again at higher heat.
- Season immediately: Always salt fries right after frying for best flavor.
- Serve right away: This dish is best enjoyed fresh and hot.
Flavor Variations
- Spicy twist: Add chili powder or cayenne pepper to the batter.
- Herb-infused batter: Mix in dried parsley or dill for added aroma.
- Garlic lovers: Increase garlic powder or add fresh minced garlic to the sauce.
- Citrus upgrade: Add lemon zest to the batter for brightness.
- Air-fryer version: Use less oil and cook at high heat for a lighter alternative.
Serving Suggestions

Serve Crispy Fish Fillets with Fries with fresh lemon wedges for squeezing over the fish. A simple side salad with a light vinaigrette balances the richness of the dish. You can also add coleslaw for a classic pairing that brings crunch and freshness.
For a complete meal, consider serving with soft bread rolls or a light soup starter.
Storage and Freezing Instructions
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 2 days.
- Reheating: Reheat in an oven or air fryer to restore crispiness. Avoid microwaving, as it softens the coating.
- Freezing: Freeze cooked fish fillets in a single layer, then transfer to a freezer-safe bag for up to 1 month.
- Fries: Best enjoyed fresh, but can be reheated in the oven.

FAQ About Crispy Fish Fillets with Fries
Can I bake the fish instead of frying?
Yes, you can bake the fish for a healthier option. While it won’t be as crispy as deep frying, you can still achieve a nice texture by using a wire rack and high oven temperature. Lightly spray the batter-coated fish with oil before baking.
What is the best fish to use?
White fish like cod or haddock works best because of its mild flavor and flaky texture. These types hold up well during frying and absorb the batter nicely without becoming dense.
Why is my batter not crispy?
This usually happens if the oil is not hot enough or the batter is too thick. Make sure your oil is at the correct temperature and your batter is smooth and slightly runny. Also, avoid overmixing.
Can I make the batter ahead of time?
It’s best to make the batter fresh. The sparkling water loses its bubbles over time, which affects the lightness and crispiness of the coating.
How do I keep fried fish crispy longer?
Place the fried fish on a wire rack instead of paper towels after draining. This prevents steam from softening the crust and helps maintain crispiness.
Is tartar sauce necessary?
Not at all, but it adds a delicious tangy contrast to the fried fish. You can also serve with ketchup, garlic sauce, or yogurt-based dips if preferred.
