Peanut Oil for Frying & Deep Frying: Ultimate Guide

Peanut oil is a common oil that is used in many Asian and Chinese kitchens to cook foods at high temperatures.

But it is also becoming very popular globally for its flavor and ability to withstand deep frying. 

So in this article we are going to be guide you on everything you need to know when frying with peanut oil.

Is Peanut Oil Good For Deep-Frying & High-Heat Frying

Yes, peanut oil is a great choice for regular frying, deep-frying and high-heat frying. 

In comparison to many other commercial oils, such as canola and soybean oil, regular peanut oil contains a greater amount of saturated fatty acids which is one of the reasons why it is suitable for high-temperature cooking like frying.

Highly unsaturated oils like soybean oil are less stable and more prone to oxidation, even though they are healthier for you.

This means that even though unsaturated oils may be healthier, they will not withstand the deep-frying process well and may very well burn your food. Peanut oil on the other hand can handle high heat and is relatively healthy.

Why Peanut Oil is Suitable For Deep-Frying

  1. High smoke point – Fast cooking at high temperatures results in a crispy coating with minimal oil absorption.
  2. Refined peanut oil has a mild taste, in contrast to other crude oil’s nutty smell and taste. As a result, refined peanut oil has no impact on the flavor of the dishes that have been prepared.
  3. Very mild scent – When using peanut oil for frying, the production of off-flavors and odors is quite minimal.
  4. In comparison to many other normal vegetable oils, such as standard soybean oil, peanut oil is more stable since it has a substantially larger proportion of saturated fatty acids. As a result, peanut oil is more resistant to prolonged high-heat exposure, which reduces the production of dangerous oxidation products.

What is the Smoke Point Of Peanut Oil

Another thing worth mentioning that makes peanut oil great for high-heat cooking is its smoke point, which is 437℉ (225℃). 

This is relatively high and means that this oil can be heated all the way to 437℉ (225℃) before it starts to burn and oxidize or break down. 

Most foods are deep fried between 350℉ and 400℉.
