Although it is peanut oil, you won’t find the taste of peanuts overwhelming due to its supreme lightness.

Grapeseed oil is another fantastic choice to deep fry your fish and leave it crispy and delicious. If you want to pan-fry or saute your fish, La Tourangelle Grapeseed Oil could be the ideal choice for you.

Spectrum Naturals Organic Hi Heat Sunflower Oil, 32 Ounce

We’ve seen canola, peanut, and grapeseed oil but now is the turn of sunflower oil. Spectrum Natural Organic Hi Heat Sunflower Oil is derived from the seeds of sunflowers.

These seeds are pressed and the oil is regularly used for frying foods. Sporting a natural flavor, this sunflower oil won’t interfere with the taste of your fish.

If you’re in the mood for some fish and chips, Spectrum Naturals sunflower oil is the best option. Sunflower oil is perfect for producing light and crispy fried fish as well as potatoes. You should be careful which sunflower oil you purchase, however.

It is advised you opt for refined sunflower oil as it typically has a higher smoke point than unrefined varieties. Refined sunflower oils usually range from 440 to 450 °F while unrefined oils have a smoking point of around 225 °F which isn’t suitable for deep-frying fish.

Other oils that are higher in these fats are always a better and healthier choice, especially when cooking with high heat.

  • High in monounsaturated fats - Very beneficial to your health, supporting weight loss, decreasing the risk of heart disease, and decreasing inflammation

Best Oils for Deep Frying Fish Buying Guide

Now you have seen the 5 best oils for getting your fish crispy and delicious, there are some key considerations to look out for when choosing the right oil.

The Smoke Point

If you don’t consider anything else, you should definitely look at the smoke point of the oil. For deep frying, it is recommended you find an oil with a high smoke point. This is because deep-frying temperatures generally reach 350 to 375 °F.

Oil with a lower smoke point than these temperatures will begin to break down and become useless for deep frying any food, let alone fish. Always ensure the oil you are purchasing for deep frying can handle the extreme heat necessary.

The Flavor

It is recommended you choose an oil with a neutral flavor as these won’t interfere with the taste of the fish, especially when deep-fried.

The oil should have one primary job, to make your fish crispy. If it overpowers the flavor of the fish, you could spoil the meal. Therefore, it’s important the oil is light with a mild or neutral taste so you can still tell what fish you are eating once it is fried.

Choosing an oil that impedes the flavor transfer is also something to consider. If you’re not sure what flavor transfer is, it’s when oil absorbs all the flavors of the food you are deep frying. The oil then keeps that food’s flavor and transfers it to the next batch of food that needs to be fried.

You shouldn’t use the oil you deep-fried fish in with other foods anyway as the combined flavors could be terrible. It’s advised you avoid mixing different types of fish with the same oil but, if you have to, choosing an oil that doesn’t transfer such flavors will help you the next time you have to fry something tasty.

Refined vs Unrefined

Refined oils are the types you want to use when deep-frying fish. These usually have a much higher smoking point so can, therefore, withstand higher heat than unrefined oils.

Refined oil has better oxidation stability which helps it withstand heat and, at the same time, maintain its original flavor and fat content.

Olive oil has strong stability and a high smoke point so is an ideal choice for deep frying fish. Refined oil is also more pure meaning that there is more oil and fewer impurities in the ingredients when compared to unrefined oil.

Although most oils are labeled as refined, you can tell if it’s truly refined by its bright gold color. This usually points to the oil having less of a flavor which is perfect for deep frying.

There are some drawbacks of using refined oils as several are highly processed and lose a lot of their healthy fats once past their smoking point. Many oils also come from GMO (genetically modified organism) plants which can be unhealthy due to toxic fertilizers and pesticides that they are sprayed with.

Always check the ingredients and whether the oil has come from GMO-plants if you are against this.


What are the best oils to use when deep frying a fish?

If you’re looking for a budget-friendly option, 100% peanut oil or non-GMO cold-pressed vegetable oil are the best choices. These usually herald great results and don’t take anything away from your fish’s flavor.

Another option is to use blended oils including a premium oil. Oils such as these can have a premium blend of olive oil and canola oil which are an ideal combination for getting your fish light and crispy without losing any flavors.

If you’re looking for the healthiest option, you should go for coconut oil. This oil has a high resistance to heat due to its high amount of fatty acids. As well as this, coconut oil has a neutral, slightly sweet flavor that can complement many meals.

Lastly, you could opt for straight premium oil which is either refined or cold-pressed olive or avocado oil. Although these oils tend to be costlier than others, they usually last longer than refined vegetable oils.

What is the best way to deep fry fish?

Not all fish are suitable for deep frying such as salmon or tuna. However, catfish, halibut, and trout are some of the best fish for this type of cooking.

For the best deep-fried fish, you should:

  • Maintain a high heat - Wait for the heat to rise before submerging your fish into the oil. If you put it in too early, your fish will soak up a lot of the oil and leave it heavy and greasy. The ideal temperature for frying any fish is around 360 to 380 °F.
  • Fry smaller pieces of fish - Never put too much fish in to deep fry as this can result in unevenly cooked fish. You should fry smaller quantities of fish, no matter what oil you are using. Check on the fish as it fries and before long, it will be ready to serve up!
