Let’s start building our pizza oven kit

Step 1: Choose A Location For Outdoor Pizza Oven

Before you construct a pizza oven, you need to determine where you want to set the oven. Choosing the right site is very important because once the pizza oven is placed, it can not be moved anywhere else. 

Choose A Location For Outdoor Pizza Oven

Make sure it is set on a stable and steady, level surface, ideally away from flammable materials and structures. Ensure there is a lot of space so you don’t have any difficulty making pizzas. 

Step 2: Foundation, Design, and Planning of Oven

Ensure that the foundation of your pizza oven is solid, reliable, durable, and long-lasting. Plan the dimensions and shape of your pizza oven. For instance, how many pizzas you want to cook at once and the space in your garden. 

Foundation, Design, and Planning of Oven

An oven with a dome shape is a popular option since it offers great heat retention and distribution.

Step 3: Pizza Oven Base Construction

  • Once the location, design, and foundation are decided, proceed with the work by digging a shallow foundation canal. The recommended size is at least approximately 120cm x 120cm square, but you can make changes according to your own preference. 
  • Now lay the concrete blocks or bricks on top of the cured foundation to create the base of your pizza oven or the outer wall. Use cement to secure the blocks or bricks together. Ensure the base is level, equal, and square, using a measuring tape to guide you.
Pizza Oven Base Construction
  • Now that the outer wall and base are constructed, it is time to fill in the center. You can use rubble and stones to do that. To make it more solid and firm, add a layer of sand. These will serve as a heat/warmth sink, which will absorb the heat as they warm up. Then, the absorbed heat will be returned through the oven. 
  • Now, add a layer of bricks on top to finalize the oven floor. This is the surface/place where you will be cooking. To make sure the entire process is done perfectly when you start using the oven, ensure the bricks fit tightly together.

Step 4: Building The Oven Dome

Make a sand mound in the oven’s preferred shape and size to serve as the foundation for the dome. Preferably, approximately 120 kg of sand will be required because the mold will be made out of the sand. 

Building The Oven Dome

In order to help the sand maintain its shape, softly wet it using newspaper and have the dome covered with it. 

Step 5: Layering The Oven Dome

Mix a batch using clay, sand, and water. Mix these three components until you have a thick texture/paste. Apply a thin layer of the mixture to the dome (no need to remove the newspapers), ensuring that the mold is secured in place. 

Layering The Oven Dome

Keep using the mixture until the layer is 7cm thick. Once you reach the desired thickness, smooth out the edges of the applied layer. Once the dome is completed, leave it to dry for 4-6 hours. 

Step 6: Creating The Opening Of The Oven

Check the dome after a few hours; once it is dried enough, it is time to cut the opening. This will be the entrance from where you will slide your pizza into the oven. Grab a kitchen knife or any safety knife to cut a hole big enough to slide a pizza inside.

Creating The Opening Of The Oven

Make sure the hole is not so big, or the oven will not retain the heat inside. Take out sand from inside the oven and let the oven dome set to dry completely overnight. 

Step 7: The Brick Opening And Chimney of the Oven 

Once the clay is all dried up, use bricks and blocks around the opening. This will serve as the entrance to your pizza oven. Secure those bricks with a mixture of sand, clay, and water. It is now time to construct a chimney. Cut a small pit in the dome, then use clay to make a lip to construct a solid base. 

The Brick Opening And Chimney of the Oven

You can also use a plant pot to serve as a chimney. You can also buy one or construct one out of the clay mixture to serve as the actual chimney. If you prefer to create one out of the clay mix, you can begin by making layers of rings of clay on top of one another. Keep layering until the required height is achieved before smoothing the clay with your hands. 

Step 8: The Final Layer of Your Pizza Oven

The last layer is now ready to be applied. Apply a handful of the clay and sand mixture to the dome’s exterior. This layer is identical to the first layer but a little thicker.

The Final Layer of Your Pizza Oven

Now, smooth out the surface and edges of the applied coating. After completing this procedure, let it sit for a few days before you proceed with lighting the newly constructed oven. 

Light Up Your Pizza Oven 

Here is the part where your newly constructed pizza oven is finally ready to use. Follow the steps below to light up and use the pizza oven: 

Light Up Your Pizza Oven
  • Add in kindlings and wood logs inside the oven. These will serve as your fuel within the oven. 
  • Now set fire to those kindlings and logs using either match stickers or a light. Once the kindling starts catching fire, add in a few more logs to bring more heat. 
  • Wait for the pizza oven to heat up to its full temperature. You can keep adding logs until the desired temperature is achieved. Utilize an infrared thermometer to inspect the temperature status. 
  • Once the desired temperature is achieved, you can slide your pizza inside the pizza oven.

When you are done using the pizza oven, make sure to clean it up from any build-up, debris, and ashes. Do not use harsh chemicals to clean the oven. Have the oven covered when it is not in use to ensure its longevity.
