Is Bacon Grease Flammable? Here Is an Answer

Bacon grease is one of the most versatile ingredients you can use in the kitchen. Whether frying food or transferring smells from one surface to another, bacon grease can do almost anything. Is bacon grease flammable? Understanding what you’re getting into before heating that bacon fat is essential.

Bacon grease is considered to be relatively flammable, and it may ignite if left on the burner of a stove or other hot surfaces. If your bacon drippings ever come in contact with a warm spot on your stove, they will catch fire. The reason comes down to the chemical structure of the fat.

To reduce the flammability risk in your fry pan, pour the hot bacon grease into a separate container and set it aside to harden. If you leave the frying pan on the stove long enough for the bacon grease to cool down, it won’t ignite.

How Flammable Is Bacon Grease

How Flammable Is Bacon Grease

Bacon grease is the fat that accumulates in the pan when you fry or bake bacon or when you cook a meal that otherwise uses bacon as an ingredient. It looks like a yellowy, sticky liquid, so flammable.

Bacon grease has a flashpoint of 212 degrees Fahrenheit, meaning it can catch fire at 212 degrees Fahrenheit or higher.

Typically, grease is considered highly flammable. However, there are different types of grease that are more or less flammable. For example, motor oil is not flammable at all.

Bacon grease contains a lot of water, making it less flammable than some types of grease. It can catch fire.

For its flammability, you can treat bacon grease like any other type of rendered fat (lard or tallow). However, the high amount of protein and sugar in bacon isn’t valid for all applications. 

Bacon grease is flammable and has a very high “flashpoint” (the temperature it will ignite).

You must be careful when handling bacon grease, especially when cooking. Because of the high flashpoint, bacon grease can burn at extremely high temperatures. For example, if you have a pan of bacon grease going at 500 degrees Fahrenheit for just a few seconds, it can catch fire.

Moreso, You should be extra careful when cooking with bacon grease. If you are frying or scrambling eggs in bacon grease, watch your pan carefully and always keep an eye on the temperature. When cleaning up after cooking with bacon grease, allow it to cool completely before pouring or scraping it out of the pan and into a trashcan or other container.

What Causes Grease Fires?

Grease fires are caused when a flammable liquid, such as cooking oil or grease, is heated to a high enough temperature to ignite. They are most commonly caused by cooking accidents, such as when oil or grease is heated to a high temperature on a stovetop or in an oven, and can also be caused by other sources of heat, such as cigarettes or open flames.

There are several factors that can contribute to the risk of a grease fire, including the type of oil or grease being used, the temperature of the cooking surface, and the presence of other flammable materials. Some oils and fats, such as olive oil and butter, have a higher smoke point (the temperature at which they will begin to break down and release smoke) than others, such as vegetable oil or lard, which can make them more prone to burning.

Similarly, cooking surfaces that are too hot or that are left unattended for a long period of time can increase the risk of a grease fire.

To prevent grease fires, it is important to be careful when cooking with oil or grease and to pay attention to the temperature of the cooking surface. It is also a good idea to keep a fire extinguisher or baking soda on hand in case of emergencies and to have a plan in place for safely extinguishing a grease fire if one occurs.

How to Put Out a Grease Fire on Grill

If you’ve had a grease fire, you know how quickly it can get out of hand. But if you do the right thing, you can put it out and prevent damage to your grill and home.

1. Turn off the gas or propane line.

2. Don’t smother the fire with a lid or towel; you’ll create an oxygen-rich environment that could worsen the fire and cause it to flare back up later. And whatever you do, don’t squirt water on it.

3. Instead, try baking soda or salt to smother the flames (be sure to wear oven mitts). Or, if you have access to a fire extinguisher or garden hose, use those instead.

When deciding whether to use water on a grease fire, it is important to remember that water and grease do not mix. Water has a lower density than oil, so after pouring water onto an oil fire, it sinks to the bottom and mixes with the hot oil.

As a result, it creates an explosion effect called spattering. Hot grease will splatter in every direction, possibly igniting a fire on your clothes, skin, or surrounding area. 

Instead of turning off the heat source, you could throw flour or baking soda onto the flames. It should smother the flames. For larger grease fires on grills outside, using a fire extinguisher would be more effective than baking soda, but remember that these are only temporary solutions. 

Does Flour Put Out a Grease Fire

Does Flour Put Out a Grease Fire

Flour is not an effective way to extinguish a grease fire. In fact, using flour or any other dry, powdery substance to try to put out a grease fire can actually make the fire worse. When flour or other dry substances are thrown onto a grease fire, they can quickly become coated with the burning grease, which can cause them to ignite and spread the fire.

The best way to extinguish a grease fire is to cut off the oxygen supply to the fire by covering the flames with a metal lid, baking sheet, or other flat, heavy object. This will help to suffocate the fire and prevent it from spreading.

If you do not have a lid or other flat object to use, you can also try using a fire extinguisher or baking soda to help put out the fire. However, it is important to use caution when using these methods, as the fire may still be hot and can reignite if it is not completely extinguished.

And if you are unable to put out the fire safely, it is important to evacuate the area immediately and to call the fire department for help. Do not try to move the pan or container that is on fire, as this could cause the fire to spread or could cause serious burns.

Why Can’t You Put Water on a Grease Fire?

You can’t put water on a grease fire because the water will sink below the grease, spread the fire, and increase heat.

If you pour water on a grease fire, it will cause the burning oil to splatter and spread, increasing the area of the fire. As a result, it will be difficult to control.

In addition, since water has a much lower boiling point than oil (212 degrees Fahrenheit vs 320-446 degrees Fahrenheit), pouring water on the fire will also cause rapid evaporation, creating steam. This sudden flash expansion can easily knock you off your feet, and further spread the fire.

Furthermore, If a grease fire occurs, the best thing to do is turn off the heat source and cover the flames with a metal lid or cookie sheet. DO NOT use water, towels, or other clothes, as these are flammable materials that can easily catch fire.

Can Grease in Oven Catch Fire

Cooking grease can catch fire in the oven. Use a thermometer to ensure your oven is cooking at the correct temperature. Check it regularly to make sure it is not malfunctioning and overheating.

Suppose you spill grease on your oven floor while cooking; clean it up immediately. Don’t use a self-cleaning feature in your oven if you have one until you are sure that all of your kitchen’s greases have been removed.

Always keep an eye on what you are cooking. Turn down the heat or pull food out of the oven if you notice any smoke or flames coming from your food.

Cook with extra caution when using your broiler. Broilers can cause oil and fat to flare up easily, so keep an eye on foods cooked under the broiler and move them back if they smoke or give off large flames.

Additionally, the grease could catch fire if you’re baking something in the oven and your oven’s temperature rises above 600 °F.

Where to Put Bacon Grease

Bacon grease should be saved and used in other recipes. It’s an excellent substitute for butter or oil and adds a smoky flavor to foods. 

Here are a few suggestions on how to use bacon grease:

  1. Mix it with flour to make gravy. Make sure you strain the grease first, then mix it with equal parts flour and water until you get a thin paste. Heat the mixture over medium heat and keep stirring until it thickens into gravy.
  2. Use it as an ingredient in mashed potatoes. Heat some bacon drippings with chopped onions, garlic, and celery, then add them to your mashed potatoes before serving.
  3. Make fried chicken tenders with bacon drippings instead of vegetable oil or butter. This recipe uses 1/4 cup of rendered bacon fat to coat 12 chicken tenders coated in cornmeal batter and fried at 350 degrees F for about 20 minutes or until golden brown.
  4. Use it as an ingredient in homemade biscuits or cornbread. Add enough bacon drippings (1/2 cup) to the biscuit or cornbread recipe to taste the smoky flavor without overpowering the dish (this is especially good if you’re using cheese grits).

How to Discard Bacon Grease

How to Discard Bacon Grease

The easiest way to dispose of grease is to let it solidify in the pan, then throw it out in the garbage. And while this is less messy than pouring it into the sink, there are still better options.

One good way to avoid clogged pipes is to pour your grease into a container you can throw in the trash or recycle. The safest container option is glass; plastic can melt, and metal can warp. Once you use all your bacon grease, wash your glass jar with soap and hot water, then reuse it for future bacon-cooking sessions.

Another solution is to pour your grease into an old coffee can or heatproof bowl and put it in the refrigerator until it solidifies, then toss it in the trash.

  • In the garbage: This simple option won’t harm anyone or anything. However, keep in mind that bacon grease is still pretty oily and greasy, so if you’re using plastic bags, it will get all over them and make for a smelly mess when you throw them away.

On the other hand, cleaning the bags out could compensate for the time saved by not having to clean out an alternate container for the grease.

  • Pour into glass jars: Glass jars are great because they’re food-safe, easy to clean, and can go into the dishwasher. Just pour the cooled liquid fat directly into a jar with a lid.

What Does Rancid Bacon Grease Look Like

Rancid bacon grease can look like wet sand or mud. The color is typically dark or brownish, and the consistency is gritty. The grease may also be clumpy and feel thick and heavy in your hand.

You might also notice a change in smell, which may be unpleasant or “off.” For example, if you see mold growth on the bacon grease, it has gone bad and should be thrown out.

Furthermore, It will have a dark, cloudy appearance and a very strong odor. It can also get moldy if left out of the fridge for too long, so keep an eye out for fuzzy green spots in your grease. Once your grease has spoiled, it should be thrown away immediately before cooking.

Is Bacon Grease Good for Dogs?

Bacon grease, or any other type of animal fat, is not a healthy or safe food for dogs to consume. While bacon grease may have a tempting flavor for dogs, it is high in fat and cholesterol and can cause gastrointestinal upset and other health problems if ingested in large amounts.

Additionally, bacon grease can contribute to obesity and other health problems in dogs if it is fed to them regularly.

In general, it is best to avoid feeding your dog any type of processed or high-fat foods, including bacon grease, as they can be harmful to their health. Instead, it is important to provide your dog with a balanced diet that is appropriate for their size, breed, and age, and to consult with a veterinarian if you have any questions or concerns about your dog’s nutrition.

If you do accidentally feed your dog bacon grease or any other type of unhealthy food, it is important to monitor them for any signs of illness or distress. Symptoms of gastrointestinal upset in dogs can include vomiting, diarrhea, loss of appetite, and abdominal pain. If your dog experiences any of these symptoms after eating bacon grease or any other unhealthy food, it is important to contact your veterinarian for advice.

Can You Use Bacon Grease to Season Cast Iron?

Can You Use Bacon Grease to Season Cast Iron

One of the most common ways to season cast iron is by coating it with a layer of oil and reheating it. In a pinch, bacon grease will work just fine as your oil. It isn’t ideal, however.

When using bacon grease, clean your pan thoroughly after seasoning it, so the bacon flavor doesn’t get transferred onto your other dishes.

Meanwhile, searching for cast iron seasoning on the Internet won’t be long before you come across several references to using bacon grease as a seasoned cooking surface.

The claim is that the fat from the bacon penetrates the surface and permanently “seals” it without any special process such as heating to high temps. Using some simple science, we are going to test this claim.


Bacon grease can be used for several purposes; however, is bacon grease flammable? Bacon grease is flammable. It contains primarily fat, which is a hydrocarbon that is chemically similar to gasoline.

However, it’s unlikely that you’ll be able to ignite strips of bacon grease unless they’re in a vessel that allows flames to spark up, though you should always exercise caution when dealing with open flames and fatty food.
