Follow this step-by-step guide to make a fireless cooker from items you probably already have on hand.


How to cook without electricity


One of the small appliances in my kitchen that I really rely on is my slow-cooker. It allows me to cook dinner without slaving over a hot stove all day.


But if the power goes out, that slow-cooker is a paperweight, unable to cook anything without electricity.

On our homestead, storms come through in the spring and fall that can knock out our electric power for hours, days, and even longer. In winter, ice storms can do the same.


Without electricity, my slow-cooker of course doesn't work. Electric stoves won't work either. Gas and propane stoves need electricity to ignite the cooking flame. 


But beyond power outages, there's another aspect that troubles me: leaving the house with the oven or slow-cooker running. Whether I'm out of the kitchen tending to chores in the pasture or making a quick trip to town, I don't leave appliances on.


However, there's a fascinating solution that harkens back to the resourcefulness of our ancestors, allowing us to enjoy a hot dinner whether we have electricity or not, whether we were in the house all day or working outside.


Here's how cooks of the past made a hot dinner and still got a hard day's work done: they used a straw box cooker, also known as a fireless cooker.


What is a fireless cooker? - an introduction to safe indoor cooking without electricity


In its original form, a straw box cooker (or fireless cooker) was a wooden box that held a hot pot of food. Straw, hay, sawdust or other insulation was stuffed around the pot inside the box to hold in the heat.. 


The pot of food was first heated up on the stove or in the oven, then put into the "straw box" to finish cooking using the retained heat.


Why you need a way to cook without electricity - the advantages of fireless cooking


Losing electricity isn't the only situation where you might want to use a straw box cooker, or fireless cooker as they are sometimes called.


It's an excellent reason to use one though. I'm sharing our personal experience with an ice storm that knocked out our power further down in this post.


But it's not the only reason. What if ...

  • you need to work outside all day, perhaps baling hay, or putting up a fence, or working in the garden
  • you're going on a road trip and would like to take dinner along so you can save money on a restaurant meal
  • you want to take a hot meal to a new mother, or to a sick friend
  • you're on a camping trip and want to spend the day hiking or fishing and then come back to camp where a hot meal awaits you


Think outside the "box" and you'll find many situations where a straw box cooker would be helpful!


Modern adaptations of the straw box cooker - where can you buy a fireless cooker


There are a few modern adaptations of the straw box cooker, if you'd prefer to buy something that fits your needs. But I'm going to show you how to make a straw box cooker with items you probably already have on hand below.


There are slow cookers, roasters and other cooking appliances with 12 volt power that are designed and marketed for truckers and travel. These items use the power of your vehicle to warm up and cook your food.


You can also buy thermal cookers such as this one. These consist of inner pots that nestle inside a thermos-type outer pot, and work similarly to the traditional straw box cooker, where you must warm up the food first, then transfer it into your homemade fireless cooker to continue cooking.


How to make a straw box cooker


You probably already have everything you need to make this simple straw box cooker:

  • an ice chest/cooler
  • a folded bath towel (or use a thick layer of newspaper such as the big Sunday edition)
  • a blanket or two
  • a heavy pot with lid that fits inside the cooler

An ice chest or cooler is a perfect container for your homemade fireless cooker. It's insulated so it holds in the thermal heat. It's airtight, which will also hold in the heat. 


And you probably already have one in the garage, right?


A folded bath towel on the bottom of the cooler insulates the bottom of the pot, holding the heat in. It also keeps the hot pot from melting the bottom of a plastic ice chest! 


A really thick layer of newspaper (like a Sunday paper) works just as well as a towel. 


The blanket helps hold in the heat (no straw needed in this modern version), and the tightly-closed lid of the cooler creates an insulated box that holds in the heat and cooks your food.


How to use a fireless cooker


The cooking process in a straw box cooker is very simple.


Test your pots and pans first to be sure one will fit inside the ice chest, without enough space on all sides for the blanket to wrap around it. 


A heavy pot is best, and it must have a well-fitting lid.


To use the straw box cooker, bring your food to boiling on your stove or other source of heat. 


Place the folded towel on the bottom of the ice chest, then lay the blanket on top in a single layer.

Place the folded bath towel inside the cooler, and spread out the blanket.


Set the hot pot of food on top of the folded bath towel and one layer of the blanket, inside the ice chest.


Wrap the rest of the blanket around the hot pot, and stuff the rest of the blanket around it to completely enclose the pot and fill the empty space in the cooler.


If there is empty space between the blanket and the cooler lid, add another blanket, more bath towels or even an old pillow. The goal is to stuff as much insulation inside the cooler as possible, and have no empty air space.


Then just shut the lid of the cooler tightly, and walk away.


By dinnertime your meal will be hot and ready to eat.


Heat your food to boiling first


Yes, you do need a source of heat to get started. 


Of course this isn't a problem if you have electricity and are using your straw box cooker to cook without power while you're away from home. 


However if you are in the middle of a power outage, you will need to heat your food to boiling in a different manner. 


You can heat your food in one of many ways:

  • Use a camping stove which uses small canisters of propane or butane as fuel. (We have this camping stove.)
  • Heat your food on your BBQ grill's burner. This is the method we used recently after our neighborhood was hit by a tornado and we were without power for 5 days.
  • If you're camping, you can heat your pot of food on a campfire while you're making breakfast. Your dinner will continue to cook all day in the fireless cooker. 


Whichever method you choose to warm up your food, the fuel needed to heat your food will be minimal. Once you've moved your meal into the fireless cooker you won't need any added heat at all to continue cooking your meal.


Remember that this method of cooking is similar to using an electric slow-cooker. You'll need to allow several hours for your meal to cook in the straw box cooker.

Tips for using a straw box cooker


For best results, move your partially cooked food from stove top to straw box cooker quickly to conserve heat. Do not open the lid. 


Have the blanket already lining the cooler and the folded towel placed in the bottom. Bring your food to a full rolling boil, then carefully move the pot of food, cover it all quickly with the blanket and shut the lid tightly.

After adding the pot of hot food to your straw box cooker, stuff the rest of the blanket over the pot and around the edges. Add another blanket or towel if there is extra space left on top.


Allow enough cooking time to cook your food thoroughly by starting dinner early in the day. If it's something that you'd cook for eight hours in a slow-cooker, let it cook for at least eight hours in your straw box cooker too.


What to cook in a straw box cooker


Soups and stews are excellent fireless meals to prepare this way but don't overlook such dishes as baked beans or pot roast.


If it's a dish you can make in a slow cooker, you can make it in your fireless cooker too. Allow at least as much time as you would in a slow cooker.


Examples


What are some excellent fireless food items? You might like to know what we've cooked in our homemade straw box cooker.


When we had a dangerous ice storm in our forecast, I started lamb stew in the slow-cooker that morning, just in case.


We did lose power, but I simply moved the "crock" of hot food into my cooler-turned-straw-box-cooker and let it finish cooking. 


On the second day of that ice storm power outage I opened a quart Mason jar of chicken and stock that I'd pressure-canned (a large can of chicken would work just as well), added a can of great northern beans, some dehydrated mushrooms and onions, and spices for white chili.


After bringing it to a boil on our camp stove, I transferred the lidded pot to the straw box cooker, where it simmered away all day long. 


Dinner was delicious!

A cookbook for the straw box cooker


Cookbooks for thermal meals are few and far between, but these two might work for your needs:

Several coolers and ice chests
Coolers and ice chests are pretty easy to find at yard sales.

How to store your straw box cooker


When your meal is finished, leave the top of your ice chest open for a while to dry it out; it's steamy and damp inside. Air out your blanket and towel before storing them to prevent mildew.


You can return your blankets and towels to the linen closet, or you can store them inside the cooler for the next time they're needed.


The cooler can be stored in the garage or wherever you normally keep it. Keep the drain plug on the cooler closed to help keep bugs out during storage.


A straw box cooker is a great use for an ice chest


Ice chests can often be purchased for $5 or so at yard sales, and you can use the pots and pans you already own. Make sure your pots and pans fit inside the cooler before you need to use your straw box cooker.


Using what you already have makes this a very inexpensive alternative to a slow-cooker - and you don't have to wait for a power outage to use it.


Putting a hot dish in this insulated chest is an excellent way to transport food to a potluck supper or to a picnic in the park with family or friends. Take it on a camping trip. It's a great solution for those who live off-grid too.


It's also a frugal way to save money on your power bill: just bring your dinner to a boil, then transfer into your prepared straw box cooker/ice chest to cook until dinner time while you work on another project.
