The amount of oil you use in a deep fryer is determined by the type of food you’re preparing, as well as the kind of fryer you have. However, a good rule of thumb is to never put more than half of the basin full.

We’ve put up a list of typical meals that may be prepared in a deep fryer and the best methods for doing so. Simply, we know you’ll want the most personalized assistance to keep you safe in the kitchen. We’ve gathered a list of frequent meals that may be cooked in a deep fryer and given some helpful tips.

Type of fryer that you’ll need

There are actually a few distinct types of deep fryers on the market.:

  • Electric Fryers: Easier, more convenient, but often compact, which restricts you from frying veggies and tiny protein chunks.
  • Propane Fryers: Often referred to as producing a superior taste, but they require a little more finesse than electric varieties. They must be utilized outside, for example.
  • Air Fryers: Oil-based deep fryers are not the only way to cook french fries. They don’t yield the same results, but some people like them for their health benefits. We won’t go into detail about them here since you have a choice, but keep in mind that they’re available.

Kind of oil to put in your fryer:

Different oils have different smoke points, which means they can withstand different temperatures before beginning to burn and give off a foul smell.

Olive oil: This is one of the best choices since it has a fairly high smoking point (400 degrees F) and has an agreeable flavor.

All-purpose vegetable oil: This is also fairly versatile in that it is healthier than other options like lard or shortening. However, you need to monitor the temperature when using this type of oil closely; overheating can make your food taste icky.

Peanut Oil: This option has a very high smoke point (450 degrees F) and is perfect for deep frying anything from chicken wings to doughnuts. Just be careful about any allergy concerns if somebody in your house is allergic to nuts.

Lard: If you don’t mind the taste, this option has a high smoking point (370 degrees F) and can be used for many kinds of foods. It’s especially good for dishes that include potatoes, like potato chips or french fries.

How much oil do you put in a 6-quart deep fryer?

These are the most popular fryers, so we’ll focus on them in terms of measurements. For standard electric, six quarts is an average volume, but there are several different sizes to choose from. However, it’s fine if you want to go slightly over the halfway mark.

The thing to keep in mind is that it’s a bad idea to fill your deep fryer to the brim because it will make for an extremely dangerous situation. It won’t just be difficult to refill, but if you ever tip over the basin, it will spill hot oil everywhere and lead to terrible results.

The average deep fryer will take about five quarts of oil, but three or four is usually sufficient. You can add vegetables or whatever you’re cooking in the deep fryer up to the halfway point.

Gas deep fryers are a different story. These need just over two and a half quarts of oil since they have a higher capacity than electric models. Regardless, it’s always best to follow manufacturer recommendations when it comes to filling a gas fryer with oil.

There are too many recipes that you can prepare with an air fryer that doesn’t even require any kind of frying whatsoever. Essentially, for this type of appliance, there isn’t much use in knowing how much oil you’ll need – only what types of foods work best in it.

Steps to follow when you are filling your deep fryer with oil

  1. The first step is pretty obvious, but it’s important that you don’t have any open flames or anything that could cause a spark while you’re refilling the deep fryer. If there’s an automatic shutoff feature on your electric machine, make sure it’s switched off before getting started. You should never fill up a hot deep fryer with oil – do so only after it has cooled down.
  2. It may seem like common sense, but we’ll remind everyone just in case: never ever add cold oil to a hot deep fryer. Again, this will result in dangerous steam and splatter and can definitely lead to injury if you aren’t careful.
  3. If you’re using a propane fryer, never ever attempt to move it when there is hot oil inside. It will be very heavy and the last thing you want to do is drop it or tip it over. In fact, there’s no need for caution if you have an electric deep fryer – just carry on as usual.
  4. Finally, let the oil cool before discarding it in a safe manner. Never pour hot oil down your drain – this causes clogs and other issues that are best avoided. You can also return it to its container and bring it back to a store for disposal by professionals – just ask if that’s possible first!

How much oil do you put in a commercial deep fryer?

There is no specific amount of oil that you need to use when deep frying with your electric deep fryer. There are some things to keep in mind, though:

  • All-electric deep fryers have a maximum capacity of approximately 2.5 liters. This means you shouldn’t overfill your fryer with oil because the oil will spill out if it reaches its maximum capacity – making a huge mess!
  • To ensure optimal results, never go above halfway on most electric deep fryers. If the manufacturer says 3 quarts is the max, don’t fill up more than 1/3 of your container. The hot oil can also cause pressure to build up inside the fryer, which may result in an explosion if too much oil has been poured in.
  • If you’re using a very large pot (such as an 8-quart pot), it’s important to note that the heat distribution will be different – so only fill the deep fryer halfway. You should also use low or medium heat, rather than high heat, during cooking so the oil doesn’t overheat and become dangerous.
  • That being said, never ever attempt to move a hot oil-filled gas fryer! They’re too heavy and can lead to dangerous spills if you aren’t careful when moving them.
  • Oil capacity is not something that’s especially important to know, but it’s definitely worth keeping track of. If you’re looking for an oil-less deep fryer, then this information won’t help much.

Other things to keep in mind

When using any kind of oil, remember that it will rise as it gets hotter. Be sure to use caution when adding food to your deep fryer so that you don’t get burned by splattering oil. Also, never add water or other liquids while the unit is hot; let it cool first and then remove the basin and wipe out any leftover residue with a clean cloth.

Keep in mind that after cooking, you should never leave oil sitting in your deep fryer. Dump it, let it cool, and dispose of it or recycle it correctly.


Whether you’re looking to impress guests with steak fries or simply want to feed the family fried chicken, a deep fryer can be one of the most versatile appliances in your kitchen. If you follow this guide on how much oil does a deep fryer use? then cooking with oil will be much safer for everyone.
