As part of a recent giveaway, one of the questions I asked was “What DIY project would you like to see featured on Backdoor Survival?” There were some amazing responses and over time, I hope to work through the list.
Interestingly enough, two readers requested a similar topic and when more than one reader makes a request, I sit up and pay attention. The DIY projects were:
1. How can I build a bread-baking oven with mud and straw?
2. I would like to learn how to build a Horno oven (traditional Native American wood-fired oven).
As luck would have it, this is a familiar topic since awhile back, I featured an article on DIY mud ovens. I had first seen one at the Mother Earth News Fair and was fascinated by its simplicity as well as its efficiency. I was later contacted by a Backdoor Survival reader who had built his own mud oven and was willing to share some hands-on tips. Later, during one of my travels, I found some mud ovens in actual use in both Mexico and Costa Rica. I was hooked!
For those of you that are new to the concept, outdoor Mud Ovens are common in third world countries where indoor cooking facilities are nominal and where cooking fuel consists of wood and biomass. They are also known in some areas as Horno ovens.

How to Build an Outdoor Mud Oven
Rocket stoves and outdoor grills are great for cooking in a pot or skillet when the power is down or non-existent following a disaster or a worst case SHTF situation where fuel is either flat-out unavailable or intolerably expensive.
There are some things, though, that cook best in an oven. One solution, of course, is to use a cast iron Dutch oven or camp stove. These are great options, sure, but what about something made from the ground we stand on? I am referring to what is commonly called a “Mud Oven”. Until my recent visit to the Mother Earth News Fair in Puyallup, Washington, I did not know such a thing existed. Live and learn, right?
What is a Mud Oven and How Does it Work?
Mud Ovens have been in use for thousands of years and are made of a clay-sand mixture baked by the wood fire used to heat it. The way they work is that a fire is set, the oven is heated then the cooking is done by retained heat after the fire is removed. Food cooked by this method are cooked slowly and evenly with almost no chance of burning.

Mud ovens have many other names: Earth Oven, Clay Oven, Adobe Oven, Bee Hive Oven, Quebec Oven, Roman Oven and El Horno. The difference between these various ovens are in the materials used to build them, what they look like, and where they are used.
I have got to tell you, when I first saw the mud oven I was fascinated. I began thinking about baking breads and pizzas in this primitive but time honored way and wanted to learn more. Imagine my surprise when a Backdoor Survival reader out of the clear blue shared his experience building a mud oven with me!
The Quest for A Mud Oven
Cary from Texas had this to say about his quest to build a mud oven:
I had traveled Arizona and New Mexico visiting places such as Acoma, Taos Pueblo and any other places that had mud ovens.
I remember in the late sixties buying bread baked in these ovens and wanted to duplicate the experience in my own back yard. I also wanted a go to cooking method that was efficient and low cost. The fuel can be anything that burns from nice oak split logs or old pallets torn apart and chopped up. The fire is small and uses very little wood to heat the oven to 500 degrees F.
Then comes the part most people can’t fathom. When the fire burns down to coals you remove it. There is no fire in the oven during cooking. The base becomes a heat sink and the oven walls are 10 inches thick so they hold heat also. You can place your hand on the exterior during peak heat and although hot it will not burn your hand.
The very first firing went as follows. About thirty or more minutes of burning wood and then i removed the coals. Several pizzas were cooked which took about two minutes each. They go directly on the firebrick floor. Then i put two loaves of bread in to bake and removed them 30 minutes later. I hadn’t planned anything past that so i put the door back in place while i made up a pot of dry pinto beans, yes dry, with plenty of water and some seasoning.
I had little hope for this but tried it anyway. I made some mud to seal the door and walked away at 2:30 that afternoon. I checked the oven the next morning and it was still hot and the beans had cooked to a creamy texture and were delicious.
How Do You Build a Mud Oven?
There are lots of instructions on the internet but first, follow along as Cary shares his construction via some great photos (used with his permission, of course).
Base for heat sink being laid out.
As for the building of a mud oven the most critical mindset to have is you can fail and lose nothing. Reuse the old mud and start over.
Walls for heat sink homemade adobe brick.
The second most critical mindset is the oven doesn’t have to be perfect and probably won’t be. You only have a few rules and they deal with clay and sand content of the mud which is basically adobe. Remember, this is 3000 year old technology and if they made it work, so can you.
Solid adobe plug that hold massive amounts of heat and radiates out during cooking
Fire brick cooking floor. The ancients just used the mud floor.
Damp play sand in the shape of a beehive. You build mud over this form.
Door cut out and sand removed. The oven gets another 31/2 inches of adobe with wood shavings as an insulator. Then a final 1 inch finish coat.
So, the first step is do some research, read Kikos book (see below) and find some friends to help with the heavy work. I built mine at 68 years of age with no help. I wouldn’t do it again without at least one helper. If you are young and in good shape then go for it but remember mud gets heavy and you have to mix a lot of it.
Good luck.
The Final Word
Most sources, including Cary, consider the best book on mud ovens to be “Build Your Own Earth Oven: A Low-Cost Wood-Fired Mud Oven; Simple Sourdough Bread; Perfect Loaves” by Kiko Denzer. In addition, there are some pretty decent instructions for building your own mud oven at the Mother Earth News website in the article Build Your Own Wood-fired Earth Oven.
Mud ovens can be built in all sizes and take little in the way of time to maintain. Furthermore, my guess is that these ovens were the precursor to the modern day slow cookers that we fondly call the “crock pot”. And in closing what does Cary say?
“This thing cooks anything and left closed overnight will cook cast iron beans and stews to last a week. You can hold the required scrap wood for the burn in two hands. Fire is removed before cooking and holds heat for a good 24 hours with door closed. Ancient technology. Not for everyone. Requires skill to build but doable for the DIY.”
Why not go for it and build one yourself? At the very least, print out the instructions and keep them with the rest of your survival documents. That is what I plan to do.
Enjoy your next adventure through common sense and thoughtful preparation!

We’ve been stumbling around the internet and found your blog along the way.
We love your work! What a great corner of the internet 🙂
Nice article but for me, the only way to fly is with a rocket oven. Mine looks very similar to the photo in this article but with just a single handful of small sticks, I can cook a pizza or load of bread. The times are the same as for my propane oven: ten minutes to preheat and then 25 minutes for cooking. Google rocket ovens and you’ll see what I mean.
Thank you for posting this. We finished our oven in March and it has had lots of use for pizza. I am still perfecting the bread baking. Ours was such fun to build and we are quite proud of it. I hope more people take on this project. We spent a total of $58 to build ours (fire bricks and straw), the rest of the supplies came right out of our own yard!
So much more simple than I expected! Yes I definitely think I’ll end up trying this. Maybe next summer.
Wow, this is really informative! Thanks for posting!!!!!
