What Can You Use Instead of Liquid Frying Oil?

When replacing one liquid frying oil with another, the most important factor is the smoke point. Sunflower and corn oil are suitable for frying at high temperatures without smoking; oils with a lower smoke point, such as olive oil, break down quickly at the same temperature. Another factor is neutral flavor: frying oil should not have a pronounced taste that could overpower the food. Whether the oil can be reused also matters. Sunflower and canola oils can be strained and reused a few times, while lower-smoke-point oils such as olive oil break down much faster when reused. Adjust the amount of oil to the food: deep-frying requires enough oil to submerge the food, while sautéing and pan-frying need much less. The oil's color and smell can also indicate whether it can be reused; discard any oil that has darkened or smells burnt. Monitoring the oil temperature with a thermometer helps keep it below the replacement oil's smoke point. After frying, strain the oil and let it cool to room temperature to help it stay fresh until its next use.

Can You Fry with Coconut Oil?
Coconut oil is described as having a high smoke point and being suitable for frying, but it has a distinctive flavor, so it is not recommended for recipes where a neutral result is wanted. Coconut oil can add a pleasant aroma when frying sweet pastries; in savory recipes, that aroma is generally an unwanted change.

Can You Substitute Canola Oil for Sunflower Oil?
Canola oil has a smoke point similar to sunflower oil and a fairly neutral taste, so the two can directly replace each other for frying. Canola oil contains slightly less saturated fat than sunflower oil, which does not change its frying performance. The only practical difference noted is that some canola oils flow a little more easily, leaving a slightly thinner coating on the fried food.

What Can You Use Instead of Corn Oil?
If you do not have corn oil, you can use soybean or canola oil; all three are described as having similarly high smoke points and behaving similarly for frying. Soybean oil may add a slight difference in flavor, but it is not noticeable in most recipes. Do not change the frying temperature for this group of oils; it is generally kept at 170–180°C / 340–355°F.

Can You Fry with Olive Oil?
Extra-virgin olive oil is described as unsuitable for deep-frying because of its low smoke point; at high heat, it starts to burn and leaves a bitter taste. Riviera or pomace olive oil has a higher smoke point and can be used for frying at medium heat. If frying with olive oil, keep the temperature below 160°C / 320°F and do not reuse the oil. Reused olive oil turns bitter quickly.

Can Butter or Clarified Butter Replace Liquid Frying Oil?
Butter burns quickly at high temperatures because it contains milk proteins, so it is not suitable for deep-frying. Use it only for low-heat browning or sautéing. Clarified butter, which has had the butter solids removed, contains no milk protein and can withstand higher temperatures, so it can be used to some extent for frying. Food fried in clarified butter takes on a pronounced buttery flavor, which may be undesirable when a neutral result is wanted.
