DIY wood fired outdoor pizza oven with simple low cost materials, also known ascob / earth oven

Recently I attended an Earth Oven (aka Cob Oven) building class taught by one of the best teachers in this field, Kiko Denzer. ( Some of the helpful resources are affiliate links. Full disclosure here. ) Years ago, I was greatly inspired by  his book : one of the best on oven building .

During the 6 hour long class, we built 2 portable earth ovens, which were auctioned the next day. I learned so much about building with earth and other readily available materials. There’s such simplicity and beauty to the process that I find deeply inspiring.

You are probably wondering –

What can you make in a simple DIY earth outdoor pizza oven? Does it really work?

These 3 pictures are from our friend Bill, who bought the earth pizza oven made by the class last year. He loves it so much and decided to join our class this year so he can build another one!

Bill has been using his DIY wood fired pizza oven almost once a week for a year now. I asked him to share what are his favorite things to make, here’s what Bill said-

” you do get a long cooking time from each firing if you think of cooking along the temperature curve with pizza first, bread, then braises of all sorts.( pulled pork,beans, rice of all ethnic cooking styles) pies and cookies and then overnight meats like carnitas. the end temp. in the cob oven is long in the 250 f range and is great for drying fruits, toasting nut’s and great grilled cheese. those are my favorites … really it works for everything that you can imagine as long as you understand a dish’s temperature requirements.”

“Here are a few shots of a fun Sunday bake. 3.5 hr fire, coals burned out and got 900 F dropping to 600 after coals out. Baked pizza, bread at 500 F then cooled to 400 F and did the bean casserole and still the next day(24hrs) oven still at 250 F for any drying of fruit!!”

OK, is this enough temptation for you to run out there and start building yet?

Step by step tutorial on how to build a DIY wood fired outdoor pizza oven with simple materials.

mixing water, sand and clay to build DIY wood fired outdoor pizza oven, aka cob / earth oven

Below is a summary of each step. Download the ebook at the end for more details in each step!

Step 1: Create sand-clay mix for the earth oven

For each part of clay soil, we mix in 2-3 part sand. More sand if using pure clay. Make sure the mix does not have any sharp rocks or debris. If unsure, wear rain boots!

Put everything on a large tarp, add some water, and start singing and dancing – which means, mixing!

Folding the tarp is a good way to get everything mixed more thoroughly.
You will know that your mixture is a good consistency and ready to go if you can form it into a ball about 3″ diameter, drop it to the ground, and the ball holds its shape with little cracking. How fun it is that our work is to dance in the mud?

Step 2: Make a base with insulation for your outdoor pizza oven

The cob ovens we made in class had a base of sheet metal bolted onto a wood frame ( pictures below ) to be portable, then placed on a sturdy foundation at their new home.

If you are building a wood fired outdoor pizza oven directly in your backyard, then consider the following keys to a foundation: stability, height, and insulation.

building foundation for DIY wood fired outdoor pizza oven, aka cob / earth oven

1. stability: a foundation can be built out of any sturdy materials such as broken concrete, brick, masonry block, stone, rocks, old tables or even wooden pallets, as long as it can hold an oven (which can weigh 300 to 600 lbs depending on size) without sinking and shifting.

2. height: the foundation should support your oven at a height that allows you to work comfortably!

3. insulation: there should be a minimum of 4″-6″ of insulation between the fire brick oven floor and the masonry or wood foundation. The insulation will prevent the masonry from absorbing all the valuable heat we want for cooking, and protect the wood foundation from burning. The glass jars and vermiculite provide insulation. The fire brick hearth is set on top of that.

Step 3: Build a sand form size of the cob oven interior

Just like building a sand castle! The sand is scooped out after the next 2 layers are built.

Step 4: Build the thermal layer for an effective wood fired outdoor pizza oven

The purpose of the thermal layer is to hold heat in its dense mass. Use the clay-sand mix we made earlier, take one handful at a time, and press it down to form a 2″-3″ shell outside the sand form. Be careful not to press into the sand form, which would cause the form to shift.

We also made a “molding” around the earth oven door opening using strands of straw dipped in clay, and formed it around the door opening to give it a more finished look and as a starting place for the next layer.

  2. This is AMAZING! I’ve always wanted to build a wood fried oven but I don’t think I have the patience to ever finish it <3

  5. What, whoa! This is crazy cool. If I owned a house, or wanted to build my own oven from scratch (omg), I’d be all about it. But instead I’d prefer hanging out with other friends who’d have this hahaha. IMAGINE the pizzas. Ugh, good lord. I bet they would be heaven… on…earth.

  10. This is so cool!! I have never seen a blog post even remotely similar to this. This would be perfect for summer cooking so it wouldn’t heat up your house! When I get a house of my own, this is first on the list of outdoor necessities. GREAT post!!

  16. WOW! My jaw literally dropped when I saw how cool this was! I would TOTALLY be down to do something like this. Oh man, pizza… I used to work a pizza station at an authentic Italian restaurant, and though it’s very hot, I never got tired of that bubbly charred pizza aroma! ^_^

  18. You always share the coolest stuff and I am here for it! I bet the pizza’s in the earth oven are good! That’s def a big project to do with friends!!! I could totally see myself trying to jazz it up!

  23. I’ve seen these done before, I’ve always felt there just amazing and the bread I’ve had bake in one of them was brilliant, just wish I had the space to have one 🙂

  28. I would love to be able to make this or even attend a class! I only need the right garden/backyard 😉 I can only imagine the satisfaction of cooking in this oven after having built it from scratch.

    • hi steve, I’m no expert, but it’s like any wood fired ovens, deserves another book on this topic! =)

  38. I do not understand one essential thing: you can make fire but not cook at the same time..? So once you made the fire, you must wait for it to consume and then get it out and then clean the base and then cook a pizza?

    Reply

    • hi adrian, the very first fire is to cure the oven. when you cook with it in the future, the oven gets hotter as the fire is almost burnt out, so when you clear out the ashes and coals, the inside surface of the oven releases heat and cook the pizza. people get to know their ovens as to how much wood to burn and when to stop the fire to cook! =)

  40. Great, but it doesn’t seem to have any space for cooking things.. there is space only for fire and wood, isn’t it?

  41. What a wonderful idea, I would love to print out the plans and make my own oven, included in the new BBQ area I’m working on.

  45. Ooooooo I’ve always wanted one of these and the hubby will only eat pizza that has a “wood burnt” base. I can’t wait to show him the tutorial. Thank you Ananda
