Can You Use Vegetable Oil in a Deep Fryer? (EVERYTHING You Need To Know!)

Deep frying is a favorite way to cook meat and vegetables, but many people don’t know how to use vegetable oil in a deep fryer. The good news is that it’s easy.

Just follow these steps and you’ll be deep-frying like a pro in no time!

Vegetable oil is one of the most popular choices for deep frying

Vegetable oil is one of the most popular choices for deep frying. If you’re looking for a healthy, safe, and convenient way to cook your favorite foods without worrying about the consequences, vegetable oil is a great choice.

Can you reuse vegetable oil for frying?

If you want to reuse oil for frying, it’s best to filter the oil and refrigerate it. You can reuse vegetable oil as long as it isn’t rancid or contaminated by other food.

To avoid contamination and keep your deep-frying tools clean, it’s recommended that you use new oil each time. If you’re in a pinch though, let’s say you forgot to buy more vegetable shortening before making baked goods. You can try reusing the same batch of shortening several times if you filter out all of the solid particles that may have collected at the bottom of your container. To do this successfully:

  • Filter through cheesecloth or coffee filters into another bowl (this will remove small pieces).
  • After filtering all solids from cooked food out of the original container (and disposing of it properly), store away the vegetable oil in an air-tight container.

What are the best oils for frying?

  • Olive oil
  • Grapeseed oil
  • Canola oil
  • Coconut oil
  • Peanut oil (not the right choice for deep frying)
  • Safflower oil (a good option for frying because of its high smoke point)
  • Corn oil (it’s a decent option for frying)
  • Sunflower oil (a good choice if you’re looking to avoid GMO corn and other grains in your diet)

Again, vegetable oils are a good place to start when choosing an appropriate cooking fat.

Can you filter frying oil?

Once you’ve drained the oil, it’s time to filter it. There are several different options when it comes to filtering out food products that have been fried in vegetable oil:

Use a paper towel

The easiest way to filter your frying oil is with a paper towel! Just put your strainer over the top of a bowl, then place the paper towel over the top of that, and let it sit there for about 20 minutes. You’ll be able to squeeze out most (if not all) of the excess oil from the towel onto a plate or into another container on hand for disposal purposes later on down the road.

Use cheesecloth or cloth napkins

Instead, if you’d like something more durable than just regular old printer paper around town—just make sure those are clean before attempting this method since any dirt particles will end up getting stuck in your clean pan at some point during its lifespan which might lead towards rusting issues down further on the down road! This isn’t necessarily bad because they can still get cleaned easily enough (and sometimes even repaired), but it’s always best practice not to do things wrong first before learning how right things should’ve been done instead.

How to filter fryer oil

Before you start to filter your oil, you’re going to need some safety equipment. You’ll need some high-temperature heat-resistant gloves an apron, and a face shield for any type of splatter.

You’re also going to need a drain poker, a dial thermometer, an extension pipe for your drain, oil test strips, a high heat temperature scrub brush, and a chrome scoop.

You also need a cone filter and cone filter paper, a large stock pot, and a metal measuring pot to transfer oil.

  1. Start with checking to see if your oil needs to be treated. If it is the color brown, or it has spots in it, or it smells funny and pungent, then it’s time to filter it out.
  2. Check the temperature of the oil in the deep fryer. A temperature of between 250 to 300 degrees Fahrenheit will make it easier to scrub out any residual grease or crums.
  3. Remove any accessories that are still inside the deep fryer such as the basket if it’s still there. You can use your train poker if anything has fallen into the deep fryer and you can’t reach it.
  4. Place the large stock pot with the cone filter and a cone paper filter underneath where the drain valve empties the oil.
  5. Slowly open the drain valve and allow the oil to slowly pour out Into the cone paper filter.
  6. Using the metal measuring pot, take a scoop of the filtered oil in your stock pot and pour it back into the deep fryer so that it can be drained into the filter. This will also help carry more of the residual oil and crumbs out of the deep fryer base.
  7. Use the drain poker to get rid of any clogs that may occur inside the valve.
  8. Scrub the inside of the deep fryer base with the high heat temperature scrub brush. You can also continue to cycle the filtered hot oil in to lubricate and break up any residue that is stuck inside.
  9. Throw away the filter, seal the oil, or place a lid on top of the pot.
  10. Finally stored away in a cool and dry environment and reuse again for up to eight to 10 more uses all of which you run back through the filter again each time.

How long does vegetable oil last in a deep fryer?

Vegetable oil, in a deep fryer, will last for a long time. In fact, you can use it up to 10 times as long as you properly filter it each time correctly. But it should be replaced regularly to ensure that you can get consistent results from your recipes.

The amount of time that vegetable oil will last depends on how it is stored. If the oil is stored in a cool, dry place and not exposed to sunlight or heat, then it can last longer than if it was stored somewhere else in a heated and humid environment.

You can reuse cooking oil as long as it doesn’t smoke or have an off taste or smell. Once it starts to smoke, the oil has reached its smoking point and is no longer safe to use for frying.

Oil will also go bad faster if you use a lot of fresh ingredients in your deep frying. Fresh ingredients contain water which causes the oil to become less stable and more likely to spoil over time.

How much oil should be used for deep frying?

When you’re deep-frying, you need to have enough oil to fill the pot and allow for the food to be completely submerged. Too little oil will result in an uneven cook, and too much oil can lead to a burnt aftertaste. There are a few different ways to figure out how much vegetable oil you’ll need.

The most basic method is to measure out your pot from one side of it at its widest point and then add about three inches, which should be the height of your food when cooking. For example, if your pot is 10 inches wide but only holds 2 quarts of liquid in total (2 cups), then you’ll want about 6-7 cups of vegetable oil for this recipe.

If that doesn’t work for you or if it makes sense in some way not based on volume (i.e., if all of your recipes require at least 4 Tablespoons), here’s another way.

Put two fingers into the bottom of an empty fryer when it’s dry and make sure they don’t touch each other—that will give approximately 5 inches worth of headroom space between them when filled with liquid so that they do not touch each other inside their container! This means that anything smaller than 5 inches tall should be placed vertically while everything else could float freely within their container

What is the best oil for deep frying French fries?

The best oil for deep frying French fries is vegetable oil.

Vegetable oil is a neutral cooking fat with a high smoke point and an even flavor profile, making it ideal for frying in a deep fryer. Because of its neutral flavor and higher smoke point, vegetable oil won’t add any extra flavors to your food, whether you’re using it to make French fries or fried chicken.

If you want to get fancy with your fried foods (and who doesn’t?), consider using butter or lard as well! These fats have lower smoke points than vegetable oils do but can give foods different flavors depending on what animal they came from.

Butter has a milder taste than lard does since it comes from cows rather than pigs or sheep. If you’re looking for something more distinctively flavored than regular old vegetable oil but aren’t sure where to start experimenting with different fats, try mixing equal amounts of butter and lard together before adding them into the hot oil.

This way you’ll still get some nice texture while getting some extra depth in terms of taste too!

Is corn oil good for deep frying?

Corn oil is a good choice for deep frying because it has a high smoke point. Fabulous! But not all oils have the same properties, so you should consider your options before choosing which one to use.

The smoke point of an oil is the temperature at which it begins to break down and release unpleasant odors into your food (think burnt popcorn).

The higher an oil’s smoke point, the longer you can use it for frying before there are any negative consequences for your health or taste buds.

What is the healthiest cooking oil for deep frying?

In the world of deep-fried foods, there are many different oils you can use for frying. The most common are vegetable oil and peanut oil. However, did you know that some oils may have a higher smoke point than others? For example, olive oil has a smoke point of 375°F (190°C) while sunflower oil has a much lower one at 340°F (170°C).

If you’re looking for an alternative to vegetable or peanut oil in your deep fryer and want to know what’s best for your health, here’s the lowdown on the healthiest cooking oils for deep frying:

Olive Oil

With its high smoking point and neutral flavor profile, olive oil makes an excellent choice for cooking anything from chicken wings to french fries without adding too much extra fat. It pairs well with other flavors so it’s great if you’re looking to experiment with new sauces or marinades as well as using it alone in some recipes such as oven-fried sweet potato chips!

Canola Oil

While this may not be considered “healthy” by most people (it contains mostly monounsaturated fats), its higher smoking point compared to other oils makes it ideal when cooking at high temperatures.

What type of oil do restaurants use for deep frying?

When it comes to deep-frying, restaurants use a variety of oils, including canola oil and vegetable oil. Canola is a plant that is low in saturated fat and high in monounsaturated fat. It also contains omega-3 fatty acids which are good for you!

Vegetable oil is another popular choice because it’s inexpensive and easily accessible by most people who have their own kitchens at home.

If you’re wondering what type of oil restaurants use for deep frying, here’s what we found:

  • Restaurants use canola oil (or other types of plant-based oils) because they’re affordable options that don’t cause an increase in cholesterol levels when you eat them regularly.
  • Restaurants also choose corn oil because it has a high smoke point which means it won’t break down under heat easily so the food will stay crispy longer than other types of fats would allow for
  • That same effect with less chance of burning yourself while trying out different dishes during mealtime preparation!

How many times can you use vegetable oil in a deep fryer?

You can use the same oil for multiple batches of fried food, but if you’re using the fryer frequently, you’ll want to change out the oil every few uses. If the fryer isn’t used often and you have a lot of food left to fry, then it’s safe to use that same batch of oil for up to 8 to 10 meals.

When your oil begins to look like it has a film on top this is called “gunking” in the industry it will be time for a change. You’ll know this by looking at your food while they’re cooking: if they are browning too quickly or not getting as crispy as it should be after being fried long enough in hot oil (about 10 minutes).

Chances are your oil has lost its effectiveness and should be replaced immediately!

How to store vegetable oil between uses?

Your best bet is to store vegetable oil in a cool, dark place.

You want to avoid exposure to light, which can cause the oil to go rancid. High-temperature environments might destroy its nutrients.

Store it in a sealed container that’s not made of plastic or metal plastic containers might leach chemicals into your food and metal containers can react with the oils and make them go bad more quickly. Glass jars are fine too.

What’s the smoke point of vegetable oil?

The smoke point of vegetable oil is about 400 to 450 degrees Fahrenheit.

The smoke point of vegetable oil is the temperature at which the oil begins to break down and produce smoke.

In other words, it’s what’s keeping your deep-fried food from turning into a giant candle. So if you’re looking for a healthier option for frying up some chicken tenders or fries, don’t reach for that bottle of olive oil just yet.

Does vegetable oil affect the flavor?

Vegetable oil is a neutral oil, so it won’t alter the flavor of your food. This means that if you deep fry something in vegetable oil, you can’t taste the difference between frying it with olive oil or peanut oil, or any other type of cooking fat.

When people think about deep frying foods, they often wonder whether they will be able to tell that they were fried in vegetable oil as opposed to an animal fat like butter or lard (pork fat). The answer is no. There is nothing about frying food in vegetable oils that will alter its flavor at all!

One thing I wanted to mention is that if you don’t filter your oil or if you are using and reusing old oil, the smell of residual oil and food from the previous meals may end up contaminating your current meals. This can largely affect the flavor of your current meal.


Vegetable oil is one of the most popular choices for deep frying, but it isn’t always easy to know how many times you can use it before replacing it with a fresh batch. In general, a good rule of thumb is to change your oil at least every two weeks or after every six batches of food.

Remember that the quality of your cooking oil will affect flavor, so if you’re looking for something healthier than corn or soybean oils try using extra virgin olive oil!
