How long can you go without craving a hot, homemade meal, if you have been eating only cold rations and snacks?  If you’ve ever been without power for more than just a couple of days, eating cold ravioli or tuna out of the can gets really old, really fast. Most survival minded people realize, better than most, that it doesn’t take much to disrupt the flow of electricity we depend on for cooking. A natural disaster or freak weather event can turn the most modern home into a survivalist camp within a few hours. Electricity can also be interrupted by man-made crises, such as civil unrest, terrorism, or an EMP, making that hot meal a rare treat.

A popular slogan among survivalists and preppers is, “Always have a back-up to your back-up.”  When it comes to cooking, what is your back-up to your back-up? Do you have more than one way of cooking a hot meal when the power is down?

One simple addition to your emergency preparedness is a solar oven. It’s a great way to get started cooking off the grid, and is something everyone, not just preppers, should have on hand.

As long as the sun is shining and the sky is relatively clear, a solar oven can serve up a delicious pot of rice and beans and brownies for dessert without requiring any fuel. In fact, its dependence on the sun as its only source of fuel, is the reason every home should have a solar cooker. Solar cooking is an unbeatable back-up for making sure there’s a hot meal on the table three times a day. It’s also a sure-fire way to have hot water on hand for sanitation purposes and to purify water.

There Is Something New Under The Sun

Solar cooking and using the sun to preserve food has been around for hundreds of years, but only in modern times has the use of solar cookers become widespread both in the survival community and among communities around the world with unreliable electrical power. Its advantages are obvious.9 Reasons why your home should have a solar cooker Click To Tweet

  • There is no need to store additional fuel.
  • Sunshine is free, unlike propane, butane, gas, and other fuels.
  • It’s possible to store several months’ worth of food, but storing all the fuel you might need isn’t as easy.
  • Once paid for, or built, if you’re the DIY type, there are no other expenses involved and maintenance is simple.
  • There are no dangerous fumes or safety issues to worry about.
  • A solar cooker can be used for every type of cooking, except frying.
  • Food never burns in a solar cooker.
  • During hot, summer months, the use of a solar cooker helps keep the kitchen, and the cook cool.
  • Over time and with frequent use, the use of a solar oven will save money on the electric bill.

A Solar Cooker For Every Home

A solar cooker is a must-have as a back-up method for cooking food. It is the single most self-reliant way to cook food and heat water, and has the additional advantage of being a DIY project if there’s a handyman (or woman) in the family.

Commercially produced solar cookers, such as the All-American Sun Oven, are perfect for the prepper who is too busy for even one more DIY project. These stoves have consistent quality construction, are designed to reach temperatures for the quickest possible cooking results, and have features for enhanced usability, such as interior thermometers, large reflecting panels (optional on the Solavore), and a weather-resistant design.

However, some of these ovens carry a price tag of $300 or more and can be large and bulky. In a Get-Out-Of-Dodge scenario, there might not be room for my Sun Oven in the back of our Tahoe, and if I ever had to cook for more than my family of four, it might be too small. That’s one of the limitations of a store-bought solar cooker. You’re stuck with a standard size that may be too small, and your budget may not allow for a second cooker.

On the other hand, a DIY solar cooker can be customized to your specific needs. One friend used a large ice chest on wheels for her solar oven. She could wheel it to any location in the backyard and she chose a size that could accommodate as many as four baking dishes. Another ingenious DIY plan that can be found on the internet uses a 5 gallon bucket and a reflective sunshade. Total cost?  Not much more than ten bucks, if that. The advantage of many DIY solar cookers is that they can be dismantled for convenient transport, and all of them require materials that are already in most garages. Plans for homemade solar cookers can be found on dozens of websites and demonstration videos abound on YouTube.

The DIY solar cooker comes with a few disadvantages. If the design doesn’t maximize the amount of sunlight available, you may end up with nothing more than a hot silver box sitting out in your yard. I recommend testing and tweaking any DIY design until it consistently reaches 350 degrees or more. Reliable temperatures will help you plan mealtimes and insure that foods reach temperatures that will deter any bacterial growth. Another issue with the DIY cooker is its durability. If a slight breeze knocks over your cooker and pot of beans, you’ll know you need to fine-tune the design for added stability.

Getting Started With Solar Cooking

Regardless of which solar cooker you settle on, some foods are easiest for getting started.  Be sure to keep a log of foods you cook, time of day you begin cooking, and the length of cooking time required. This log will be a huge help to you as you branch out and begin cooking a wider variety of foods.

  • Hard boiled eggs. Place eggs on a dark colored towel or inside a dark pot inside your cooker.  After 20 minutes, check one egg for doneness. Solar cooked hard boiled eggs will be softer than those cooked in a pot of boiling water.
  • Rice is either cooked or it’s not. It’s probably the easiest food to experiment with when you’re new to solar cooking. Combine rice and water in a covered pot. Check for doneness after 25 minutes. A package of Rice-a-Roni works just as well for your experimentation.
  • Yes, brownies! Mix up a batch of your favorite store-bought or homemade recipe, pour it into a dark, greased pan and place it in your solar cooker. Use the baking times recommended by your recipe, test for doneness, and leave in for additional minutes if required. I’ve found that solar-baked brownies are usually finished in the same amount of time as oven-baked.
  • Heat water in your solar cooker to pasteurize it. Check the temperature of water after 30 minutes. At 149 degrees Fahrenheit (65 degrees Celsius), all germs, viruses, and parasites are killed. This information, along with your solar cooker, could be one more way to insure safe drinking water in an emergency and provide sterilized water for medical and first aid purposes.

Like any new skill, the only way to learn how to cook with a solar oven is to just do it. For most dishes, allow at least an extra 30 minutes to your cooking time. Here are more tips for successful solar cooking.

If you’re new to solar cooking, prepare to be amazed.  There’s nothing quite like placing a baking dish in a box out in the sun and coming back later to a fully cooked and delicious meal.  A prolonged power outage doesn’t mean the end to hot, nutritious meals when you have a solar cooker as a back-up.

  1. I never though about cooking with a solar oven. After reading this, I might give this a try. Thanks for the eye opener.

  2. When I lived down in Az`s desert, I made one of those 5 gallon bucket with sun-shield cooker. It worked quite well. i cooked several meals and brownies and banana bread. Unfortunately I left it on my patio… and a monsoon rolled through while I was at work. . Bye, bye… I figure most of it ended 2 counties away. 😛

  3. I really like your comment about always having a backup to your backup. We lived off the grid for over 8 years. We cooked with either a propane stove, a propane BBQ grill, or a wood fire in our yard.

    We wanted to try a solar oven but never got around to doing it. Primarily because we had so many trees that it would be shaded a lot of the time.

    Now, however, it’s a different story. We’ve moved to a different home that is still in the forest but it gets more sun exposure.

    I’ve been meaning to build a solar oven and do some experiments with it. Specifically, I want to measure the ambient air temperature and compare it to the temperature inside of the solar oven. I’ll pop back into this post and let you know what my results are.

  4. This was a great article and, truly, what an easy preparedness item to have on hand and learn to use – especially compared to some other survival stuff! We love ours and I’ll be so happy to share this post with my readers – thanks!

  5. Could you recommend a good DIY instructional webpage? Want to try this but don’t want to waste time and money on inefficient design.

  6. have you used a fresnel lens to do any cooking yet? we have one from a projector tv we saved, just have not done anything with it yet.

    1. The Survival Mom

      No, but you are the second or third person to suggest this recently! Are there YouTube videos showing how to do this?

  7. How well does solar cooking work in winter in the northern parts of the country? I live in Eastern Washington where power outages can happen in winter with a foot of snow on the ground.

    1. The Survival Mom

      It’s the amount of sun a solar cooker gets, not the ambient temperature. I’ve seen the Sun Oven used successfully in the snow.

  8. Adam @ Born Prepper

    Great article Lisa, though I doubt solar cooking in the UK would work too well, as we don’t get that much sun lol.

    Great read never the less.

    1. The Survival Mom

      After living in Phoenix for many years with 350 days of sunshine per year, or so it seemed, I now live in a forest. If a solar oven was my own cooking source, I would be in big trouble!

  9. We’ve used the Sun Oven for years. Living in southwest New Mexico in the summer can be challenging in the summer. So cooking out doors keeps the heat out of the kitchen, saves on gas bills, and electric bills too. We love our Sun Oven. It’s a great survival tool. You should try it!
