The Best Oils Used for Frying

Before discussing if you can mix cooking oils, you must understand the best available for cooking. The list below details some of the most popular which are also mentioned later in the article.

Can You Mix Oils for Frying?

Overall, it is okay for you to mix oils when cooking if you need to. The mixture will be ready for frying, however, when it reaches the lower temperature. It will not rely on the average of the two oils but the lower smoke point.

Mixing Oils for Frying

Below, you will find some of the most common oil combinations for frying. Each will describe in detail the steps you need to take and the best cooking temperature.

Can You Mix Crisco and Vegetable Oil?

Crisco shortening is technically hydrogenated vegetable oil. The latter is just the liquid form that exists at room temperature.

If you heat Crisco, it will immediately turn into a liquid. This change makes it easy to combine the two ingredients. Crisco will still have a lower smoke point than vegetable oil, however.

Making the Mixture

To create this mixture, you will start by melting the shortening. Place the Crisco on a pan on your stovetop on low heat. You want it to melt to ensure you have the amount you need.

Add the vegetable oil to the pan. Allow the mixture to reach the highest possible smoke point at 410 degrees Fahrenheit, then bring it back to a standard cooking temperature. Eventually, the two will blend as they should.

Mixing Vegetable Oil and Olive Oil

Olive oil has a higher smoke point than vegetable oil. Typically, it will reach anywhere from 374 to 405 degrees Fahrenheit.

Most individuals advise that you do not use extra virgin olive oil. This ingredient has a lower smoke point at only 350 degrees Fahrenheit. It makes it harder to combine the two oils, especially since vegetable oil, as aforementioned, has a much higher temperature.


How to Mix Olive Oil and Canola Oil

The mixture of olive and canola oil is commonplace among many food manufacturers. The latter has a light flavor, but it cooks faster than the former. It still allows the flavors of olive oil to come through in your food.

You want to wait until the temperature gets to at least 375 degrees Fahrenheit before adding your food. You will also want to put the canola oil in the deep fryer first because, as mentioned, it warms up faster.

Can You Mix Peanut Oil and Vegetable Oil?

When you mix peanut and vegetable oil, the smoke point will be the lower of the two. The former gets to 450 degrees Fahrenheit, and the latter 400. Your deep fryer should get to about 400 degrees Fahrenheit.

The smoke point of peanut oil does vary depending on the brand that you choose to use. Make sure to read the label of whatever you decide to purchase.

Mixing Peanut Oil and Canola Oil?

Peanut oil has a strong flavor that will come through when you mix it with canola oil. Both of the ingredients have a high smoke point that is well over 400 degrees Fahrenheit, however. They will cook well together overall.

Mix Coconut Oil and Vegetable Oil

The mixture of coconut oil and vegetable oil is one of the most difficult that you can make. The former is quick to burn, so you should never let it get to the smoke point of the latter.

Coconut oil has a smoke point of 350 degrees Fahrenheit. Only let your deep fryer get to that temperature, meaning your food may take a little longer to cook. You must also understand that coconut oils do leave behind a nutty flavor.

Mix Bacon Grease and Vegetable Oil

You can mix bacon grease and baking oil if you focus on the former’s smoke point. It is around 374 degrees Fahrenheit.

When you cook with baking grease, you run the risk of making your food rancid. The particles left behind from the breakfast food may lead to inaccuracies in the temperature, making the oils break down. This mixture is best for baking or sautéing.

Can You Mix Vegetable Oil and Avocado Oil?

Avocado oil has the highest smoke point out of all of those mentioned up until now. The 25% fat in this ingredient reaches 520 degrees Fahrenheit.

You have to be careful when deep-frying vegetable oil mixed with avocado oil. You do not want to go above the smoke point of the former.

The mixture of avocado oil and vegetable oil may be best for sautéing. The high temperatures are best for this type of cooking.

How to Mix Sesame Oil and Vegetable Oil

Sesame oil is a common ingredient when sautéing Asian-infusion dishes. It reaches a smoke point of 420 degrees Fahrenheit.

When combining the two of these ingredients for deep frying, the temperature results are inaccurate. It is still a strong option if you want to create stir-fry, however.


Mix Butter and Vegetable Oil

The smoke point of butter is only 302 degrees Fahrenheit. It is near impossible to deep fry anything successfully at this low temperature. You would wait for a very long time, running the risk of burning the oil mixture.

Use the stovetop to pan-fry using the butter and vegetable oil mixture. Make sure to wait for the former to melt before you add the latter liquid.

Is Mixing Oils Bad?

When you purchase a pre-processed oil, you already have to work with a mixture. You do not have to worry, however, as these ingredients go through a variety of tests.

The manufacturers will test the smoke point and the performance of the oil you need to purchase to start. They will even experiment with its compatibility and taste to ensure they produce the best possible product.

Overall, however, it is not a bad thing to mix two oils. You will likely not notice a flavor difference unless you use a strong product like peanut or coconut oil. Remember, you will monitor the deep fryer to ensure it does not go above the lower smoke point of the two.

What to Do with Oil When Done Frying

When you finish frying using your mixture, you likely want to know how to dispose of your oil. Make sure you wait to let the grease cool down to start, however. If it is hot, it can cause damage and melt the surfaces in your home.

When the grease is cool, you will need to scrape it into a container you can put in the trash. Secure it in a plastic bag so that it does not leak. Grease can cause damage to the environment and animals.

Start Frying!

If you are low on oil, do not be afraid to combine two types. Make sure that your deep fryer only reaches the lower smoke point of the two, however, to prevent burning and enhance flavor. 


Is It Okay to Mix Vegetable Oil and Olive Oil for Frying?

It is possible to mix vegetable and olive oil as long as you do not use extra virgin olive oil. The latter has a high smoke point that can get up to 405 degrees Fahrenheit.

Most olive oils, however, only reach around 390 degrees Fahrenheit. This temperature is slightly lower than that of vegetable oil. Do not let your deep fryer get to any hotter than the smoke point of olive oil.

Can You Mix Olive Oil and Canola Oil When Frying?

Mixing olive oil and canola oil is allowed when cooking! The latter has a very light flavor, so you will still achieve the full flavor of the former in your food.

The smoke point of canola oil is 400 degrees Fahrenheit. For olive oil, it is up to 405 degrees Fahrenheit. All in all, the two have very similar cooking temperatures. Start by only setting the deep fryer to 375 degrees Fahrenheit, however, so that you do not burn anything.

Which Oil Should You Not Use for Frying?

There are not really any oils that you cannot use for frying. Extra virgin olive oil has a low smoke point, however. This low temperature makes it difficult to cook your food efficiently and with full flavor. Most agree too that butter also has too low of a temperature to cook with on its own.

Can You Mix Old and New Oil When Frying?

You can mix old oil and new oil for frying if you do not want to waste anything. Only add a small about of the used grease with the unused. Mixing the two will actually give your food a better flavor, and your deep fryer will work more efficiently.
