Reheating fish and chips can sometimes be a tricky task, especially when you want to maintain that iconic crispy texture of the battered fish and hot, crunchy French fries. Whether it’s leftover battered fish from your favorite fish and chip shop or leftover seafood that you’ve stored in the fridge, the key to good reheating is choosing the right method to preserve the texture, flavor, and safety of the food. In this guide, we’ll dive deep into various methods to reheat fried fish, chips, and even other seafood dishes like fish cakes and fish stew.
Proper Reheating Techniques
Before we explore specific methods, it’s essential to understand why the reheating process matters so much. Properly reheating fish not only helps maintain a crispy texture but also ensures food safety. Battered fish and fries are already cooked, but improper reheating can lead to a slimy texture or dry, dry fish that’s tough to eat. Additionally, if leftover fish fillets or cooked fish are not reheated to the right internal temperature, they can become a breeding ground for bacteria, posing a risk of food poisoning.
The temperature danger zone for food is between 40°F and 140°F (4°C – 60°C). This is where bacteria can grow quickly, and if food sits in this range too long, it can lead to health issues. Food hygiene & safety should always be a priority when handling seafood leftovers.
Methods for Reheating Fish and Chips
There are several ways to reheat your fish and chips, and the method you choose will depend on the tools you have available and the desired outcome. Let’s take a closer look at each method.
Reheating in an Air Fryer: A Crispy, Quick Solution
An air fryer is one of the best ways to reheat leftover fried fish and chips. It uses hot air circulation to mimic the effect of deep frying, resulting in a crispy texture without the extra fat. The air fryer ensures that the fish maintains its crispy batter and that the fries stay crunchy, avoiding the dreaded sogginess that can come with other methods.
Steps to Reheat Fish and Chips in an Air Fryer:
- Preheat the air fryer to 350°F (175°C).
- Place your leftover fish fillets and French fries in the air fryer basket. Make sure to arrange them in a single layer, as overcrowding will cause uneven heating.
- Heat for around 3-5 minutes, flipping the fish and fries halfway through the process. This ensures that both sides become golden and crispy.
- Once the fish reaches an internal temperature of 165°F (74°C), it is safe to eat. If you want extra crispiness, you can cook it for another 1-2 minutes.
- Serve immediately with salt and vinegar or tartar sauce, and enjoy your crispy fish just like it was freshly made!

This method works particularly well for battered fish and oven chips, ensuring they retain their restaurant-quality crispiness.
Reheating in a Toaster Oven: A Great Alternative for Small Portions
If you don’t have an air fryer, a toaster oven is another excellent option for reheating fried fish and chips. Toaster ovens function similarly to conventional ovens but are smaller and more energy-efficient. They heat food quickly, ensuring that the fish stays moist and the batter stays crispy.
Steps to Reheat Fish and Chips in a Toaster Oven:
- Preheat your toaster oven to 375°F (190°C).
- Line a baking tray with baking paper or aluminum foil to prevent sticking and for easy cleanup.
- Place the fish fillets and fries on the tray, ensuring they are in a single layer.
- For fried fish, cover the fish with a piece of aluminum foil to keep the moisture in and prevent it from drying out.
- Reheat for about 5-7 minutes or until the internal temperature of the fish reaches 165°F (74°C). For extra crispiness, uncover the foil in the last 1-2 minutes to allow the fish to crisp up.
- Check that the fish is hot and crispy before serving.
The toaster oven is perfect if you’re reheating smaller portions, making it a convenient and quick solution for your leftovers.
Reheating in a Conventional Oven: Ideal for Larger Portions
When reheating a larger amount of leftover fish and chips, a conventional oven is often the best choice. The even heat from a conventional oven can restore the crispy texture of the chips and fish batter, ensuring that everything heats evenly without drying out.
Steps to Reheat Fish and Chips in a Conventional Oven:
- Preheat your oven to 375°F (190°C).
- Lay your leftover fried fish and French fries on a baking sheet. Line the sheet with baking paper or aluminum foil for easier cleanup.
- Arrange the food in a single layer. This is essential for even heating, especially for fish fillets and chips that are thicker or larger in size.
- Reheat for 10-15 minutes, flipping the fries halfway through and checking the fish after 7 minutes to ensure it is crispy and at the correct internal temperature.
- Once the fish has reached an internal temperature of 165°F (74°C), it’s ready to serve.
Using a conventional oven works well for battered fish, but it can take a bit longer than other methods. However, it’s perfect for reheating multiple servings of fish and chips at once.
Microwaving Fish: The Quickest Method (But Not Ideal for Texture)
While the microwave is undoubtedly the fastest way to reheat food, it is not the best option for keeping fried fish and chips crispy. Microwaving fish can cause it to become soggy or develop a slimy texture, especially if the fish was fried or battered.
However, if you’re in a hurry, here’s how you can minimize the negative effects:
Steps to Reheat Fish and Chips in the Microwave:
- Place the fish and fries on a microwave-safe plate. If you have a piece of seafood that’s unbreaded, you can also microwave it, though it won’t achieve the same crispiness.
- Cover the fish with a damp paper towel to trap moisture and prevent it from drying out.
- Microwave on high for about 1-2 minutes, checking the internal temperature of the fish to ensure it’s reached 165°F (74°C).
- If the fries are too soggy, you can finish them off in a toaster oven or air fryer to restore their crispy texture.
While microwaving is quick, it’s not recommended for fried fish and chips if you care about texture.
How to Handle Fishy Smells During Reheating
One of the common complaints when reheating fried fish is the fishy smell that can linger in the kitchen. While this is natural, there are a few tips to minimize the pungent fish aroma during reheating:
- Cover the fish: Using aluminum foil or baking paper to cover the fish helps contain the smell.
- Use ventilation: Open a window or use your range hood vent to direct the smell outside.
- Baking soda: Place a bowl of baking soda nearby to help absorb the odor during the reheating process.
- Lemon: Adding a slice of lemon to your fish before reheating can help neutralize the fishy smell.
