How To Cook While Camping Without A Fire

Camping With No Fire

Cooking during a camping spree is a vital activity that sometimes determines surviving in the wild or not. Most of the time, we have a fire to cook, but you may not be in a position to do so and thus will be left wondering how to cook while camping without a fire.

Based on many years of camping experience and research, I have found various cooking methods while camping without a fire. Some of these are very useful, especially if you want to cook inside a tent.

Cooking by fire has been considered a norm by most people in the wild due to several perceived advantages. These include scaring away some nosy wild animals’ source of light and warmth during the night.

It is economical as you use the forest’s available resources, among others. However, on a rainy day and a  site with campfire restrictions, staying without fire is inevitable, the only option to consider. Let this not worry you anymore.

How to Cook While Camping Without Fire

There are several ways to cook your food ranging from using a hot car engine, heat packs, solar cookers, flameless ration heaters, portable electric cookers, mixing vinegar with baking soda, and pre-cooked food recipes.

The pre-cooked food recipes are considered old school, but trust me, old is gold in one way or the other. You can boil eggs and carry them along to last you for days during breakfast. Away from this cliché way of doing things, let’s look at the flameless options and enjoy a warm meal.

1. Using A Hot Car Engine

Car engines can get pretty hot, especially after a vehicle has been driven long distances. This heat can be used for cooking on a camping trip.

Cooking with a car engine is achievable when other options are not viable—if the machine is not already hot, revving the vehicle up or placing a weight in the gar pedal (stone or wooden block) while in parking position will heat the engine.

Before using the engine, it’s essential to confirm the gas level so that you do not run out of gas when cooking.

To use this technique, turn on the car to heat the engine. Once the engine has reached a substantial temperature, turn off the engine and place the pan or wrap your food in foil and make sure the food is leak-proof while on the engine block. Riding the car idly for some minutes will maintain the heat required.

Funny story, my boyfriend did this thinking he was Bear grills. Little did he know he didn’t wrap the food tight enough, and it dripped all over the car engine. The car engine was stinking of chicken for a long time after! Ha!

2. Using Portable Cooking Bags With Heat Packs 

These heat packs allow you to heat and cook the food through a chemically heated pouch. After reading an article on YummyTasteFood.com, using these heat packs is highly recommended.

Magic Cook Heat Packs

Some chemical heat packs are effortless to use.

A chemical heat pack contains a pouch filled with water and chemical salt surrounding the pouch. When the pouch is broken, the salt dissolves in water.

One method is dissolving rock salt (which is calcium chloride) into water. As the salt dissolves, a chemical reaction occurs, and heat is generated as calcium chloride dissolves into ionic parts.

The temperature in some good heat packs like these Magic Cook available on Amazon can reach up to 203 Degrees Fahrenheit and are very affordable. The hot pack can maintain the heat for around twenty minutes.

Magnesium sulfate also generates the same heat when the salt dissolves in water. The good thing is that most of these heat packs can work in various environments, including snowy regions where lighting a wood fire would almost be impossible.

These heat packs also come in handy if you wonder how to keep warm while camping without a fire, especially with the widespread fire ban.

3. Solar Cooker

Most solar cookers are lightweight and foldable, making them easy to bring on camping trips.

Using a solar cooker and oven is cheap in the long run as it uses a free renewable energy source and doesn’t pollute the environment.

They come in various shapes and sizes and are easy to use. To cook, set the solar oven in an area with an unobstructed view of the sun for several hours.

After placing your food inside, secure a clear lid and clip on the reflector. There is no risk of burning the food as it acts as a slow cooker and retains all the beautiful flavors and nutrients.

Some of them connected to a solar panel can be charged and used later when needed. Solar ovens are okay for both vegetarian camping food and non-vegetarian too.

I recommend the Sunflair Solar Oven, which is available on Amazon.

4. Flameless Ration Heater (FRH)

The heater makes use of the electron transfer process to generate heat. The heater consists of a bag lined with a fine powder of magnesium metal mixed with a bit of table salt and iron.

It is activated by water to form an exothermic chemical reaction that can be used to heat food. It is simple to use as you open the bag, put the meal in a container, and place it inside.

Water is added until the marked water line is reached. Approximately 15 minutes after the meal is ready. You should be cautious while removing the food from the bag due to the heat.

Flameless Ration Heaters are affordable, too, like this one we have been using on our mountaineering camping trips. On Amazon, you can grab the one called Old Faithful Flameless Geyser Portable Cooking System. 

5. Portable Electric Cooker

Portable electric stoves are safer to use as they have no gas leaks and do not emit hazardous gases such as carbon monoxide and nitrogen dioxide when cooking.

However, when cooking, you will require a constant source of electricity, such as a generator or a good battery throughout the cooking. Therefore, it cannot be used on a camping site with no power, generator, or battery.

I have been using the Sandoo Induction Cooktop due to its lightweight nature, good shape for backpacking, and ease to clean.

6. Self-Heating Can

This is a modification of the ubiquitous food can in which there are two chambers, one surrounding the other. The food is placed in the innermost compartment in one type, while the chemicals to generate heat are in the outermost.

To heat the contents, a ring on the can is pulled to break the barrier, and heat from the reaction is absorbed by the food. A different can may have the chemical in the inner chamber and food or beverage in the outer chamber.

To heat, the user pushes on the bottom of the can to break the barrier. These cans are not used widespread as they are expensive.

8. Mixing Vinegar With Baking Soda

Heat can be generated by using two commonly used kitchen chemicals. Neutralizing vinegar with baking soda forms a solution containing sodium acetate, water, and carbon dioxide.

Evaporation of the solution until crystals from a solution of sodium acetate. Then cool the solution and place it in a plastic bag alongside a thin metal. As crystallization happens on the metal and heat is generated.

This heat can be used for cooking while camping without a fire (i.e., a visible fire).

9. Propane Camp Stove

Where fire restrictions prohibit wood and charcoal fires, a propane camp stove is widely used. It is quick to set up, lightweight, and is easy to control the heat required.

To start cooking, always confirm the fuel is adequate. Connect the propane to the stove with a pipe connector. Use the igniter to light the stove, and you are ready to cook.

I have always liked the Coleman Gas Camping Stove due to its durability.

Final Thoughts

After reading this, I am pretty sure that you are no longer wondering how to cook while camping without a fire. You can camp and cook without fire and make the best of the camping experience.

It is essential, especially with the burn ban in most states.

It is good to remember that fully cooked foods that need to be reheated will be easier to heat and require little time to heat and eat rather than heating whole, non-cooked foods.
