Sweet and Sour Fish Fillet Ingredients
For the Sauce
• Tomato Ketchup – Adds sweetness and acidity; substitute with sweet chili sauce for a different flavor profile.
• Brown Sugar – Provides sweetness to balance the tanginess of the sauce; can substitute with honey or any preferred sweetener.
• Salt – Enhances flavor; adjust according to dietary preferences.
• Vinegar – Contributes to the sweet and sour flavor; rice vinegar can be a milder alternative.
• Cornstarch – Thickens the sauce and helps create a crispy batter; rice flour can serve as a gluten-free option.

For the Fish
• Fish Fillet (e.g., Cream Dory) – The base of the dish; you can substitute with any firm white fish.

• Flour – Primary component of the batter that provides structure; use gluten-free flour if necessary.
• Baking Powder – Helps create a light batter; ensure it’s fresh for the best texture.
For the Vegetables

Prepare the Sauce: In a bowl, combine tomato ketchup, brown sugar, salt, vinegar, cornstarch, and ice cold water. Mix until the sugar dissolves and the sauce is smooth; set aside.
-
Prep the Vegetables: Cut the mixed bell peppers and red onion into strips and cubes. This not only adds color but also provides a nice crunch to the dish. Set aside.
-
Marinate the Fish: Season the fish fillets with salt, pepper, and a splash of lemon juice. Let them sit for about 10 minutes to absorb the flavors.

Expert Tips for Sweet and Sour Fish Fillet
-
Oil Temperature Check: Make sure the oil is at 350°F (175°C) before frying. Use a chopstick; if it bubbles, you’re ready to go!
-
Crispy Batter: Keep the batter thin and ice cold. This prevents gluten formation, ensuring your Sweet and Sour Fish Fillet comes out perfectly crispy.
-
Avoid Overcrowding: Fry fish in batches to maintain the oil temperature. Overcrowding can lead to soggy fish instead of the desired crunchy texture.
-
Vegetable Variety: Feel free to add a mix of veggies such as carrots or sugar snap peas. This not only enhances the dish’s nutrition but also adds a beautiful splash of color.
-
Storage Wisdom: If you have leftovers, store them in an airtight container fridge for up to 3 days. Reheat gently to maintain that delightful crunch!
How to Store and Freeze Sweet and Sour Fish Fillet
-
Fridge: Store leftovers in an airtight container for up to 3 days. This keeps the sweet and sour fish fillet fresh and ready for a quick meal.
-
Freezer: For longer storage, freeze the cooked fish fillets separately in a freezer-safe bag or container for up to 2 months. Wrap well to prevent freezer burn.
-
Reheating: To reheat, place the fish in a preheated oven at 375°F (190°C) for about 10-15 minutes for a crispy texture, or microwave gently to avoid sogginess.
-
Freshness Tip: For the best taste and texture, avoid storing the sweet and sour sauce with the fish before freezing, as it can make the batter soggy.
Make Ahead Options
These Crispy Sweet and Sour Fish Fillets are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can prepare the sauce and chop the vegetables up to 24 hours in advance, refrigerating them separately to maintain freshness. Additionally, marinating the fish fillets with salt, pepper, and lemon juice can be done 3 hours prior to cooking, ensuring the flavors penetrate the fish nicely. When it’s time to serve, simply dredge the marinated fillets in cornstarch and batter, fry them until golden, and toss them in the pre-made sauce with vegetables. This way, you’ll enjoy restaurant-quality results at home with minimal effort!

Crispy Sweet and Sour Fish Fillet Recipe FAQs
What type of fish should I use for the sweet and sour fish fillet?
Absolutely! A firm white fish like Cream Dory, Cod, or Tilapia works best, as they hold up well during frying and provide a delightful texture. Feel free to experiment with any fish you enjoy!
How should I store leftovers of sweet and sour fish fillet?
To keep your leftovers fresh, place them in an airtight container in the refrigerator for up to 3 days. This way, you can enjoy the flavors again while keeping the fish as fresh as possible!
Can I freeze sweet and sour fish fillets?
Yes, you can! For freezing, ensure the fish is cooked and cooled completely, then store them in a freezer-safe bag or container for up to 2 months. To reheat, preheat your oven to 375°F (190°C) and bake for about 10-15 minutes to maintain crispiness.
What if my batter isn’t crispy?
No worries! If the batter isn’t crispy, it could be due to a couple of things. Ensure your batter is thin and cold—this prevents gluten formation. Also, frying in hot oil (350°F or 175°C) and not overcrowding the pan are crucial for achieving that perfect crunch!
Can I make this dish vegan-friendly?
Certainly! Simply substitute the fish with firm tofu or a variety of vegetables for a delightful vegan option. For the batter, use a flax egg (1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water) instead of a regular egg, and ensure your ingredients, like the sweet and sour sauce, are plant-based.
How can I prevent the fish from getting soggy during storage?
To keep your sweet and sour fish fillet crisp, store the sauce separately from the fish when refrigerating or freezing. Reheat in the oven rather than the microwave for better texture. This way, you’ll enjoy that delicious crunch when you serve it again!
