# How to Choose Oil for a Deep Fryer

There is no single best oil for every deep fryer and recipe. Start with the oils permitted by your appliance, then consider frying temperature, flavor, price and nutritional preferences. A high smoke point is useful, but it is not the only measure of an oil’s behavior during cooking.

## Check the Specific Product

Canola, peanut and suitable vegetable-oil blends are common choices, but products differ in refinement and intended use. Read the label rather than assuming that every oil with the same plant name has one smoke point.

For example, [Crisco lists frying](https://crisco.com/products/pure-canola-oil/) as a use for its Pure Canola Oil. That product example is more useful than assigning an unsupported 468°F smoke point to every canola oil. Use the temperature required by your recipe and appliance, and stop if the oil begins to smoke.

## Consider Flavor and Cost

A mild oil is helpful when you want the food’s flavor to stand out. Other oils have a noticeable flavor that may or may not suit the recipe. Compare the actual products and local prices rather than assuming one type is always cheapest.

The amount needed comes from the fryer’s instructions, not a universal two-cup minimum. Do not choose an oil solely because you expect an unlimited number of reuses. The [Presto fryer manual](https://www.gopresto.com/uploads/downloads/instructions/0548102.pdf) gives model-specific oil quantities and use instructions.

## Separate Nutrition From Heat Performance

An oil’s ability to tolerate a cooking temperature does not make it the healthiest choice overall. The [American Heart Association recommends](https://www.heart.org/en/healthy-living/healthy-eating/eat-smart/fats/fats-in-foods) replacing saturated fats with unsaturated fats, including both monounsaturated and polyunsaturated fats.

Coconut oil is high in saturated fat, so heat tolerance alone does not make it a heart-healthy choice. Nor is having fewer polyunsaturated fats, by itself, a definition of a healthy oil. Consider the overall diet as well as the cooking method.

## Look After the Oil You Choose

Avoid overheating and unnecessary prolonged heating. Remove accumulated food residue as directed, and replace oil that develops an unusual odor, persistent foam or smoke during normal use. The [Centre for Food Safety](https://www.cfs.gov.hk/english/multimedia/multimedia_pub/multimedia_pub_fsf_212_04.html) explains the signs that frying oil needs replacing.

Keep the fryer clean and follow its storage instructions after the oil has cooled. Fresh oil does not make undercooked food safe: use the appropriate cooking instructions and a food thermometer where required. Check the [FoodSafety.gov charts](https://www.foodsafety.gov/food-safety-charts) for relevant safe cooking temperatures.
