How to Build a DIY Outdoor Pizza Oven: Your Ultimate Guide


Bringing the savory delight of homemade pizza to your backyard is a rewarding endeavor. Building a DIY outdoor pizza oven not only adds a touch of artisanal cooking to your outdoor space but also becomes a centerpiece for gatherings. Follow this comprehensive step-by-step guide to construct your very own outdoor pizza oven.


Materials and Tools You’ll Need:

Fire bricks

Refractory mortar

Concrete mix

Perlite or vermiculite

Metal mesh or chicken wire

Cement board

Steel angle iron

Concrete adhesive


Fireplace door (optional)


Grill grate

Plywood or melamine board

Screws and bolts


Wire brush

Circular saw

Welding equipment (if using angle iron)

Design Your Oven

Begin by creating a detailed design for your outdoor pizza oven. Consider factors like size, shape, and location in your backyard. Opt for a dome-shaped design, which is common for efficient and even heat distribution.


Build a Sturdy Base

Construct a solid and level base using concrete blocks or bricks. Ensure that the foundation can support the weight of the oven. This base serves as the essential groundwork for the entire structure.


Construct the Oven Mold

Craft a mold for the oven’s dome shape using plywood or melamine board. This mold will guide you in shaping the oven’s dome structure. Ensure the dimensions align with your design.


Mix Refractory Mortar

Prepare refractory mortar by combining fireclay with sand, following the recommended proportions. This specialized mortar is crucial for withstanding high temperatures, ensuring the longevity of your pizza oven.


Lay the Oven Dome

Layer fire bricks over the mold using refractory mortar, gradually forming the dome shape. Pay close attention to the circular pattern, and leave an opening for the entrance. Build up the dome height as per your design, filling gaps with mortar.


Add an Insulation Layer

Create an insulation layer around the oven dome using a mixture of perlite or vermiculite with concrete. Apply this layer over the exterior of the oven to enhance heat retention and overall efficiency.


Install Cement Board and Steel Angle Iron

Attach cement board to the outside of the insulation layer using concrete adhesive. This adds durability and strength. Weld or attach steel angle iron to support the oven entrance and provide a stable surface for the door.


Shape the Oven Entrance

Build the entrance using fire bricks and refractory mortar. Construct a robust frame and attach metal mesh or chicken wire to support the mortar. Ensure the entrance is wide enough for convenient pizza placement and retrieval.


Attach the Fireplace Door (Optional)

If desired, attach a fireplace door using hinges. This not only helps in retaining heat during cooking but also adds a professional touch to your outdoor pizza oven.


Curing the Oven

Allow the entire structure to dry and cure for at least a week. Initiate small fires in the oven gradually to increase the temperature. This curing process strengthens the mortar and prepares the oven for optimal cooking.


Add Finishing Touches

Install a thermometer on the exterior to monitor cooking temperatures. Place a grill grate inside the oven for easy pizza placement. Before its first use, give your DIY outdoor pizza oven a thorough cleaning with a wire brush.



Building a DIY outdoor pizza oven transforms your backyard into a culinary haven. With meticulous planning, the right materials, and attention to detail, you can create a functional and visually appealing pizza oven. Embark on this culinary journey and elevate your outdoor cooking experience with a touch of homemade authenticity.



Can I use regular concrete instead of refractory mortar?

Refractory mortar is recommended for its ability to withstand high temperatures. Opting for regular concrete might lead to cracking or breakage under extreme heat.


Is professional welding required for the steel angle iron?

If you lack welding experience, consider seeking professional assistance for proper attachment. Well-welded steel angle iron provides structural support to the oven entrance.


What type of wood is suitable for firing the pizza oven?

Choose hardwoods like oak, hickory, or fruitwood for firing your pizza oven. Avoid softwoods as they produce more smoke, potentially imparting undesirable flavors to the food.


Can the pizza oven be used for other types of cooking?

A well-designed outdoor pizza oven can be versatile, accommodating various cooking methods such as roasting and grilling, expanding its culinary applications.


How do I clean and maintain the pizza oven?

Regularly remove ashes and debris, clean the interior with a wire brush, and inspect the mortar for signs of wear. Cover the oven when not in use to protect it from the elements and ensure longevity.
