Microwaving Deep Fryers: Safe Or Not?

Deep frying in a microwave is not recommended due to safety concerns and the potential for disaster. The high temperatures required for deep frying (350-395 degrees Fahrenheit) can cause containers to rapidly expand, overbubble, or pop, leading to possible injury. Additionally, the water content in foods plays a crucial role in microwave cooking, and the presence of oil can interfere with the desired results. However, some chefs have experimented with microwave deep frying for small items like hors d'oeuvres, desserts, and tempura, and there are specific techniques for frying shallots and garlic in a microwave.

Can you microwave deep fryer?

It's possible to deep fry in a microwave but it's not recommended

It is possible to deep fry in a microwave, but it is not recommended. While it may be tempting to try this method, especially if you are short on time or don't have access to other cooking appliances, there are several reasons why you should avoid microwaving deep-fried foods.

One of the main concerns is the potential for injury. Microwaves can cause a rapid expansion effect, also known as overbubbling or popping, in liquids, and this includes hot grease. If the hot grease pops or expands rapidly, it could cause burns or splatter onto your skin or eyes, leading to serious injury. It is also difficult to control the temperature in a microwave, and most containers on the market are not designed to withstand the high temperatures required for deep frying, which range from 350 to 395 degrees Fahrenheit. This means that there is a risk of the container cracking or shattering, which could also lead to injury.

Additionally, deep frying in a microwave can create a mess and cause damage to your appliance. The hot oil can easily splash onto the walls and ceiling of the microwave, requiring a thorough cleaning afterward. It can also aerosolize oil, which can collect in the microwave and cause leaking. This can ruin your microwave and create a fire hazard.

Furthermore, deep frying in a microwave may not yield the desired results in terms of food quality. The food may not reach the necessary temperature for proper cooking, leading to soggy and greasy food. The water content in the food can also cause splattering and mess, and the cooking process may take longer than traditional deep frying.

While some sources suggest that small amounts of hors d'oeuvres, desserts, and tempura can be fried in the microwave, the potential risks and drawbacks outweigh the benefits. It is always recommended to use a traditional deep fryer or a stovetop for deep frying to ensure safety, efficiency, and the best possible outcome for your food.

Containers may not withstand the high temperatures required for deep frying

Deep frying in a microwave is not recommended due to safety concerns. One of the primary reasons is that most containers on the market are not designed to withstand the high temperatures required for deep frying.

The temperature range for deep-fat frying is typically between 350-395 degrees Fahrenheit. Plastic utensils and Corning pyroceramic dishes will not be able to withstand these temperatures. Even tempered glass products like Pyrex or Fire King may not be adequately tempered and could shatter under the intense heat.

Additionally, there is a risk of rapid expansion or an overbubbling/popping effect with liquids heated in the microwave. This could result in hot grease splattering and causing injury.

While it may be tempting to try unconventional cooking methods, it is essential to prioritize safety and use the appropriate tools and containers for the task at hand.

There is a risk of rapid expansion and hot grease could cause injury

Deep frying in a microwave is not recommended due to the risk of rapid expansion, which can lead to hot grease causing injury. This occurs when liquids are heated in the microwave and can result in an overbubbling or popping effect. If this happens with hot grease, there is a potential for injury.

The high temperatures required for deep frying (350-395 degrees Fahrenheit) can also pose a problem as most containers on the market are not designed to withstand these temperatures. Plastic utensils and Corning pyroceramic dishes will melt at these temperatures, and even tempered glass products like Pyrex or Fire King may not be able to handle the heat for extended periods.

Additionally, deep frying in a microwave can create a mess and cause slippery oil to splash around the kitchen. It is also important to consider the waste oil generated and the potential inconvenience to coworkers if using a microwave in a shared space.

While it is possible to deep fry small amounts of food in a microwave, it is not worth the risk of injury or the mess that may be created. There are alternative methods for cooking or reheating food that are safer and more effective.

Microwaves can be used for frying shallots and garlic

To fry shallots, place 3 peeled and thinly sliced shallots in a medium bowl with half a cup of vegetable oil and microwave at full power for 5 minutes. Stir and repeat microwaving in 2-minute increments until the shallots begin to brown (4 to 6 minutes total). Then, repeat stirring and microwaving in 30-second increments until the shallots are a deep golden colour (30 seconds to 2 minutes total). Using a slotted spoon, transfer the shallots to a paper towel-lined plate, season with salt, and let drain and turn crisp for about 5 minutes before serving.

To fry garlic, use half a cup of sliced or minced garlic cloves in place of shallots. After frying, dust the garlic with a teaspoon of confectioners' sugar to offset any bitterness before seasoning with salt.

It is important to note that most containers on the market are not designed to withstand the temperatures required for deep-fat frying (350-395 degrees Fahrenheit). Plastic utensils and Corning pyroceramic dishes will not withstand these high temperatures, and tempered glass products such as Pyrex or Fire King may not be tempered enough to withstand the heat for long periods of time. There is also the possibility of "rapid expansion" or an overbubbling/popping effect that is possible with liquids that have been microwaved. If this occurs with hot grease, there is a risk of injury.

Microwaves are not suitable for frying large quantities of food

Additionally, there is a risk of "rapid expansion" or an overbubbling/popping effect that can occur with liquids heated in the microwave. If this happens with hot grease, it could cause injury. The method of deep frying in a microwave also involves opening the door to drop food into the oil and again to remove it when it is ready, which increases the risk of splashing hot oil around the kitchen and causing burns.

Furthermore, frying in a microwave is not suitable for large quantities of food because it cannot produce the Maillard reaction, which is essential for achieving the desired flavour and texture in fried foods. The Maillard reaction is a chemical reaction between amino acids and reducing sugars that gives fried foods their distinctive taste and colour. It occurs only at temperatures above 150 degrees Celsius, which is higher than the boiling point of water (100 degrees Celsius). Since microwaves heat food by exciting water molecules, they cannot reach the temperatures necessary for the Maillard reaction to occur.

Finally, deep frying in a microwave can be time-consuming and inefficient, especially when compared to traditional stovetop methods. It requires multiple batches to fry a significant amount of food, and the oil must be brought back up to temperature between each batch. This process can be cumbersome and may not yield the desired results, as the oil will continue to lose heat as it cooks the food, resulting in soggy and greasy food. Therefore, it is not suitable for frying large quantities of food.
