Finishing the dome: The brick work of your dome is not complete but this isn’t the complete oven yet. The dome still has to be insulated, reinforced, and covered.
Firstly you will need to cover the dome with chicken wire. Then a half inch layer of refractory cement.
Now the main part — insulation. The best insulation out there is ceramic fiber blankets (Kaowool, Superwoold etc). You are using them use a 6 or 8 lb density. You will need a 3″ layer all around the dome. This usually means 3 x 1″ layers as they normally come in 1″ thickness.
Mineral wool will also insulate, if you are using it use 3″-5″.
Once the insulation is applied use another layer of chicken wire to hold it together.
The final layer of refractory cement goes on top of the chicken wire.
Wait for everything to harden – a few days. And then you can paint it with latex concrete paint.
We are now back to the arch which we basically left unfinished waiting for its chimney.
If your oven is going outdoor then you can use a clay pipe, it’s widely available and usually costs $10-15 depending on the length. You can use a 12″ high chimney, it will do just fine.
Of course you can also use stainless steel chimney or black stove pipe. You can use fireplace mortar to attach the chimney to the oven. If you are using a stainless steel pipe you might as well use the matching anchor plate. In this case you can just twist lock your chimney to the anchor plate.
The most common chimney diameter for an oven with under a 40″ cooking area diameter is 6″. Large than this you may want to go with 8″.
Making your oven pretty: Functionally your oven is finished – but what about the looks? Sky is the limit when it comes to this, you can cover your oven with tiles, stones, bricks, stucco, or even completely enclose it. Depending on the scope of your project (and budget) help from a professional stone mason may be required at this point.
That’s it! Now you’ll just have to cure the oven before your first baking session. We hope you enjoyed this tutorial.

Comparing Portuguese and Italian Pizza Ovens: Key Differences
A wood-fired brick pizza oven is an excellent investment for outdoor cooking, but not all ovens perform the same. While both Portuguese and Italian pizza ovens use wood fire to achieve authentic, smoky flavors, their structural differences impact heat distribution, cooking times, and versatility. Understanding these distinctions will help you choose the right oven for your cooking style.
Dome Shape and Heat Retention
These ovens differ most in dome form, which influences heat retention and dispersion.
Neapolitan-style pizza ovens have a low, compact dome to concentrate heat. This construction allows 900°F–1100°F cooking, ensuring speed. The high heat circulation gives Neapolitan pizzas their crispy, leopard-spotted crust.
The dome of a Portuguese wood-fired brick pizza oven is taller and larger. Slow-roasted foods, bread baking, and casseroles benefit from this design’s reduced direct heat intensity. It still makes fantastic pizza, but it takes longer to crisp up.
Cooking Temperatures and Performance
Italian pizza ovens heat up quickly, reaching appropriate pizza-making temperatures in 45 minutes or less, due to their small dome and heat efficiency. They can maintain high heat for 60–90 seconds, trapping in moisture and creating a crisp, blistered crust on pizzas.
Portuguese wood-fired brick pizza ovens operate at 700°F–800°F, making them more versatile. Pizzas may take 3–5 minutes to cook, making them softer and more evenly baked. Portuguese ovens are better for roasting meats, vegetables, and slow-simmering stews due to their lower heat levels.
Versatility in Cooking
Italian ovens are great for making authentic Neapolitan pizza due to their quick, high-heat cooking. Other dishes are difficult to cook due to its high temperatures.
The Portuguese pizza oven is more versatile. Its regulated heat distribution makes it ideal for artisan bread, roasted meats, and slow-cooked Portuguese meals. The Portuguese type is a good wood-fired brick pizza oven for pizza and multi-course meals.
Brick Type and Construction
Refractory bricks are used in Italian ovens to retain heat and endure severe temperatures. These premium materials make the oven durable and heat-consistent.
However, Portuguese ovens use normal clay bricks, which acquire tiny surface fractures. Cracks may appear like a negative, but they don’t impair cooking. Portuguese-style ovens are cheaper and easier to build for DIYers.
Choosing the Right Oven for Your Needs
If you love Neapolitan pizza, an Italian oven provides the high heat for a superb crust. If you want a more versatile wood-fired brick pizza oven that can suit different cooking ways, the Portuguese design is balanced and multi-functional. Both approaches make outdoor cooking real and old-fashioned, letting you make great handmade meals.
How People Modify Portuguese Ovens for Modern Outdoor Kitchens
A Portuguese wood-fired brick pizza oven is already a versatile cooking tool, but modern outdoor kitchen enthusiasts have taken it to the next level with custom modifications. By integrating smart design elements, better insulation, and multi-functional features, homeowners are transforming traditional Portuguese ovens into efficient and stylish centerpieces for their outdoor cooking spaces.
Enhanced Insulation for Better Heat Retention
Traditional Portuguese ovens use clay bricks, which naturally develop small cracks over time. While this doesn’t affect performance, many builders reinforce their ovens with high-density ceramic fiber blankets, refractory mortar, or additional layers of mineral wool. This extra insulation helps retain heat longer, reducing the need for frequent firewood refueling. Some even install thermal mass layers using refractory concrete, further enhancing heat efficiency.
Integrated Chimney and Ventilation Upgrades
While traditional Portuguese ovens feature a simple chimney at the front, modern modifications optimize airflow and smoke control. Many homeowners are upgrading to adjustable chimney dampers, which allow better temperature regulation and prevent excessive heat loss. Others add external flue extensions to redirect smoke away from seating areas, improving comfort in covered patio setups.
Hybrid Heating: Gas and Wood Combination
Some modern outdoor kitchens are incorporating dual-fuel systems, allowing users to switch between wood-fired and gas-powered cooking. By installing a gas burner attachment, homeowners can heat their Portuguese oven quickly without waiting for firewood to burn down to embers. This hybrid approach is perfect for weeknight cooking when convenience matters but still allows for authentic wood-fired flavors on special occasions.
Built-in Pizza Prep Stations and Storage
To make cooking more efficient, many people modify their Portuguese wood-fired brick pizza oven by incorporating built-in countertops, storage cabinets, and prep areas. Stone, concrete, or granite countertops provide a durable surface for assembling pizzas, while under-counter storage keeps firewood, utensils, and ingredients within easy reach. Some designs even feature pull-out cutting boards or built-in cooling compartments for dough storage.
Aesthetic Customizations with Tiles and Stonework
Since Portuguese ovens are often the focal point of an outdoor kitchen, homeowners customize their exteriors with hand-painted tiles, natural stone facades, or stucco finishes. This enhances the oven’s durability while adding a touch of Mediterranean, rustic, or modern design to match the rest of the outdoor space. Some opt for mosaic tile work around the dome, giving their oven a truly unique appearance.
Multi-Function Additions: Grills, Smokers, and More
A Portuguese wood-fired brick pizza oven isn’t just for pizza—many people modify it to accommodate grilling grates, rotisseries, or even smoking racks. With the right modifications, the oven can double as a bread oven, BBQ smoker, and slow-cooker for meats. By adding a removable cast-iron grill insert, some homeowners use their oven for searing steaks, roasting vegetables, or even baking desserts like fruit cobblers.
Lighting and Smart Features
For those who love cooking after dark, adding LED lighting around the oven base or under countertops makes nighttime use more practical. Some tech-savvy homeowners go further by installing WiFi-enabled temperature probes, which sync with smartphones to monitor cooking conditions in real time. This ensures that slow-cooked roasts or pizzas come out perfectly every time.
By integrating these modern modifications, a Portuguese wood-fired brick pizza oven can serve as the heart of a fully functional outdoor kitchen. Whether it’s enhancing insulation, upgrading ventilation, or incorporating storage and prep areas, these upgrades allow homeowners to enjoy traditional wood-fired cooking with all the conveniences of modern design.
Comparing eco-friendliness, firewood efficiency, and materials.
A Portuguese wood-fired brick pizza oven delivers traditional cuisine, but is it sustainable? Consider how these ovens affect the environment and how they may be made more energy-efficient while assessing their eco-friendliness, firewood efficiency, and construction materials.
Eco-Friendliness: A More Sustainable Cooking Option
Wood-fired brick pizza ovens are more ecological than electric or gas ones. Wood-fired cooking is greener than fossil fuel ovens, especially when utilizing responsibly produced firewood.
Portuguese ovens’ eco-friendliness depends on wood kind and burning efficiency. Oak, hickory, and maple burn cleaner and smoke less than softwoods, lowering air pollution. Kiln-dried or naturally seasoned wood reduces carbon emissions and soot.
Many builders also install smoke filters and chimney dampers. These changes manage airflow, burn wood more effectively, and reduce air pollution.
Firewood Efficiency: Heat Retention and Fuel Consumption
Due to its large thermal mass, Portuguese wood-fired brick pizza ovens hold heat for long periods. Its long, continuous heat distribution is superior to an Italian Neapolitan oven, which needs high temperatures to make pizzas rapidly.
The Portuguese oven keeps heat longer and uses less wood than the Neapolitan oven, which requires constant firewood refilling. It can bake bread, slow-cook meats, and dry herbs for hours after the fire dies down.
Some builders use high-density ceramic fiber insulation to maximize firewood efficiency. This layer stabilizes cooking temperatures and reduces wood use.
Materials: Sustainability and Longevity
The materials used in constructing a Portuguese wood-fired brick pizza oven play a crucial role in both durability and environmental impact.
- Traditional Portuguese ovens use clay bricks, which are widely available and require less energy to produce than refractory bricks. While these bricks develop small cracks over time, they still perform well and can be easily repaired with refractory mortar.
- Refractory bricks, often used in Italian pizza ovens, are more heat-resistant but have a higher environmental cost due to the energy-intensive manufacturing process.
- Natural insulation materials like mineral wool, ceramic fiber blankets, and volcanic stone can improve heat efficiency without the need for synthetic, non-biodegradable alternatives.
- Recycled materials such as reclaimed bricks and salvaged stone can also be used for the oven base or decorative elements, further reducing environmental impact.
Some eco-conscious builders go a step further by using cob (a mixture of clay, sand, and straw) as an alternative to traditional bricks, creating a highly sustainable and cost-effective option.
The Sustainable Choice for Outdoor Cooking
Portuguese wood-fired brick pizza ovens are eco-friendly, but modest adjustments can boost efficiency and sustainability. These ovens offer traditional cooking without affecting the environment by using the right firewood, insulating properly, and using low-impact materials. Wood-fired dinners can be enjoyed while reducing environmental impact by choosing oven design and maintenance.
