What Happens if You Deep Fry Ice?

The deep fryer is one of the best appliances to cook fast food. It’s used in households and restaurants to cook tasty dishes like French fries and deep-fried chicken.

However, many people don’t know how the oil in the deep fryer reacts to frozen substances.

While the deep fryer is a versatile cooker, some foods do not belong in there for safety reasons. Ice is one of those ingredients that do not belong in the deep fryer in under any circumstances.

This article will educate you on what will occur when you place ice in a deep fryer, why it causes a reaction, and some extra information about deep-frying, ice, and dry ice.

What Happens if You Deep Fry Ice?

Putting ice in the deep fryer creates an intense reaction with the hot oil, causing the ice to explode as a result of two extreme temperatures mixing.

The huge temperature difference between these two substances causes an immediate splatter and steam reaction.

Ice should never be placed in the deep fryer because it is a severe fire hazard, and people nearby can be seriously injured. Ice blows up inside the deep fryer, and it is hazardous. It can blow the lid off the deep fryer.

As well, the hot oil from the deep fryer burns skin and any objects nearby.

Why is it so dangerous?

The addition of ice into the deep fryer makes the ice explode since the temperature levels are clearly so different.

The ice quickly alters from frozen to liquid to gas, causing an immense reaction, including fiery surges. Furthermore, oil and water do not mix, so the oil quickly gets rid of the water molecules.

You’re likely wondering, ‘Why does ice explode in the deep fryer?’

Water’s boiling point is 212° F, whereas that of a high smoke point oil like canola is 401° F. This means that as soon as ice hits the hot oil, the temperature change causes an explosive reaction.

What if ice falls into the deep fryer accidentally?

Sometimes accidents happen, and if ice falls into the deep frier by accident, the most important thing is to snuff out any emerging flames. Oxygen makes things worse, so it’s best to cover the deep frier to reduce oxygen flow which puts out the flames.

What Happens if You Put Ice Cubes in a Deep Fryer?

Whether you put one piece of ice or numerous ice cubes in the deep fryer, the same reaction occurs; however, adding multiple ice cubes is extremely dangerous.

The more water (in all forms) touches the hot oil, the stronger the physical reaction between the two substances.

Water’s boiling point is at 212°F, and the oil has a temperature of roughly 375°F in the deep fryer. There’s a huge temperature difference between the two. However, the water’s freezing point is at 32°F, and that makes the total temperature difference even greater.

When two substances combine with a 343-degree temperature difference among them, the explosion can be unsafe for the cook and the kitchen.

Another problem with adding multiple ice cubes into the deep fryer is the small size of the fryer. In such a small space, mixing two substances creates high pressure. Oil reacts to the ice instantly, and the heat transfer then creates steam.

When one ice cube is added into the deep fryer, the reaction is moderate, but the reaction can be intense if you add a handful of ice cubes. In that case, you risk burning your skin, so avoid such unsafe experiments.

What Happens if You Put Dry Ice in a Deep Fryer?

Dry ice and regular ice are not the same things. When dry ice comes into contact with boiling oil, the reaction is less significant than that of frozen ice cubes.

Dry ice is solid carbon dioxide and not water. For that reason, the reaction between dry ice and hot oil is different.

While there is sizzling and splattering, it’s nowhere as powerful as the reaction between water and oil. It’s best compared to dropping frozen chicken wings into the deep frier.

Dry ice has a temperature of -109°F, and hot oil in the deep fryer has a temperature of approximately 375°F. There is a temperature difference of almost 400 F, so most people expect a violent reaction between the hot oil and dry ice.

Instead, it’s not the case because the overall reaction is much smaller than that of regular ice and oil. However, avoid putting large quantities of dry ice in the deep fryer for safety reasons because the reaction is still unsafe, even if less powerful.

What Happens if You Put Water in a Deep Fryer?

Water evaporates quickly when placed in the deep fryer’s hot oil. As a result, the same explosive reaction occurs.

However, the liquid form of water is even more dangerous than ice. The ice must melt and transition from its frozen state first before it starts to explode. Water hits the oil instantly and starts the reaction faster, and the overall effect is more violent.

When you place water and ice cubes in the deep fryer, the oil sizzles intensely, splatters, and small explosions can cause fires. Again, the amount of water that enters the hot oil determines the size of the reaction.

Do Cold Oil and Ice Mix?

No, cold oil and ice do not mix. These two substances do not mix because they each have a different density.

Oil naturally repels water which means it is hydrophobic. Thus, when the ice cube is placed into oil, it melts.

Ice has a density of 0.92 g/cm3; therefore, it floats on top of the oil. But as it melts into water, it becomes denser and sinks. The bottom line is that once the ice cube turns into water, the water sinks to the bottom while oil floats on top.

Can I Deep Fry Frozen Meat?

No, you should not deep fry frozen meat.

In fact, deep frying frozen meat is not advisable because it’s dangerous for the person handling the deep fryer.

The frozen meat (and other food) is extremely cold, and when it touches the hot oil, the reaction is explosive. Flames and hot oil splatter can burn the skin or start a kitchen fire.

Another problem is that frozen food doesn’t cook through properly, putting the consumer at risk of food poisoning and food contamination. Always allow the meat to thaw before cooking it in the deep fryer.

Tips When Using a Deep Fryer

Deep fryers are safe for use as long as you follow the correct instructions. Here are some useful tips to consider:

  • Oils with a high smoke point are the most suitable when cooking in the deep fryer. Olive oil has a light floral taste, whereas canola and sunflower oils are mostly tasteless and suitable for cooking all foods.
  • Maintain the temperature between 350-375 degrees F. Do not add liquids or frozen foods and ice no matter the cooking temperature because it’s dangerous.
  • Fry small pieces of foods which are cut into even pieces. This ensures all the food cooks simultaneously, and there are no overcooked or undercooked ingredients.
  • Use the deep fryer in a dry area only. Avoid frying food near water or wet surfaces to avoid explosive splatters.
  • Pat large food pieces dry with a paper towel before slowly placing them in the hot oil. Use tongs to prevent oil splatter burns.
  • Do not overfill the deep fryer with too much oil or too much food. Adding an excessive amount of food at once lowers the oil’s temperature, resulting in undercooked and soggy food.
  • Do not salt food before placing it in the deep fryer. When deep-frying, salt also causes a reaction when it comes into contact with the hot oil. Like water, it starts to splatter everywhere, but it also lowers the oil’s smoke point. Add salt after the food is fried to ensure it sticks to the food.


Putting ice into the deep fryer full of hot oil causes an intense reaction, and the ice explodes inside the deep fryer. This is a result of hot and cold substances mixing.

This can cause hot oil splatter or even a fire if a large quantity of ice cubes is added.

Adding dry ice to the deep fryer produces a somewhat milder reaction, but it is still dangerous.

Deep-frying frozen meat is also not advised due to the danger of injury, fire, or food poisoning if the meat does not prepare effectively.

When utilizing your deep fryer, be cautious about the effects of mixing hot and cold substances. Never mix hot oil and ice cubes or cold water in the deep fryer.
