Best Firewood for Pizza Ovens: Hardwood Guide (2026)

Quick answer: The best wood for a pizza oven is kiln-dried hardwood under 15% moisture, typically oak, ash, or cherry. Oak holds the longest coal bed and reaches 850 to 950 degrees Fahrenheit. Ash lights fastest. Cherry adds light fruity aroma. Always avoid softwoods, treated wood, and seasoned wood above 20% moisture, which all produce smoke that ruins the dough flavor.

If you have invested in a wood-fired pizza oven, whether it is an Ooni, Gozney, Alfa, Solo Stove Pi, or a custom-built brick oven, you already know that the wood you use matters as much as the dough. The wrong wood can ruin your pizza with smoke, inconsistent heat, or unwanted flavors. Here is what you need to know.

Why Hardwood (Not Softwood) for Pizza Ovens

Hardwoods like oak, hickory, maple, and ash are dense. They burn slowly, produce high heat, and generate excellent cooking coals. This is exactly what a pizza oven needs: sustained high temperatures (700 to 900 degrees Fahrenheit) for proper pizza baking.

Softwoods like pine, spruce, and fir are the wrong choice. They burn fast, produce excessive smoke and soot, deposit resin on your food and oven interior, and cannot sustain the temperatures needed for good pizza. They also create creosote buildup that is difficult to clean from your oven.

Why Kiln-Dried (Not Seasoned) for Pizza Ovens

Even with the right species, moisture content matters enormously for cooking:

• Seasoned hardwood (20% to 30% moisture): Produces moderate smoke during the initial burn. That smoke coats your oven interior and can impart bitter flavors to food. It also takes longer to reach cooking temperature because energy is wasted evaporating moisture.
• Kiln-dried hardwood (under 15% moisture): Ignites quickly, reaches cooking temperature faster, produces minimal smoke, and delivers clean heat. Your pizza tastes like pizza, not like smoke.

The Perfect Pizza Oven Fire

• Step 1: Build the fire. Place 3 to 4 small pieces of kiln-dried hardwood in the center of your oven. Add kindling or a natural fire starter underneath.
• Step 2: Preheat. Let the fire burn for 30 to 45 minutes on average. You want the flames to reach the dome of the oven and the floor to absorb heat. The oven walls should be hot to the touch (carefully).
• Step 3: Push coals to the side. Once you have a solid bed of coals, push them to one side of the oven. This gives you a cooking area next to the heat source.
• Step 4: Maintain the fire. Add 1 to 2 small pieces every 15 to 20 minutes to keep the temperature up. Do not let the fire go completely out between pizzas.
• Step 5: Cook. Slide your pizza onto the hot floor near (but not in) the coals. Rotate it every 30 to 60 seconds for even cooking. A proper Neapolitan pizza cooks in 60 to 90 seconds at 800 degrees Fahrenheit or hotter.

Timing varies by oven model, outdoor temperature, and how big the fire is. The numbers above are typical averages for home pizza ovens like Ooni Karu, Gozney Roccbox, or Solo Stove Pi.

What Size Wood for Pizza Ovens?

Most pizza ovens have relatively small openings and fireboxes. You need pieces that are:

• 12 to 16 inches long: fits inside most oven openings
• 2 to 4 inches in diameter: small enough to catch quickly, large enough to sustain heat
• Split, not round: split pieces have more surface area and ignite faster

Our 1.33 cu ft Box ($39.60) contains compact, uniform pieces that work well in standard pizza ovens. The 1.75 cu ft Mega Bag ($49.50) also works and provides more volume for extended cooking sessions or larger ovens.

Wood to Never Put in Your Pizza Oven

• Pine, spruce, fir, cedar: too much smoke, soot, and resin
• Treated or painted wood: releases toxic chemicals onto your food
• Wet or green wood: cannot reach proper temperature, excessive smoke
• Plywood or particle board: contains glue and formaldehyde
• Charcoal or briquettes: designed for grills, not pizza ovens. They do not produce the flames needed for proper oven cooking.

Cherry vs Oak vs Ash: Firing Temperatures Compared

Not all kiln-dried hardwoods perform the same in a pizza oven. The three most common choices, cherry, oak, and ash, each have a distinct firing curve. The numbers below are typical averages from home pizza-oven tests; your actual times will depend on oven model, ambient temperature, and load size.

Cherry hits around 19.5 million BTU per cord and reaches dome temperatures of 700 to 750 Fahrenheit within 35 to 40 minutes on average. The flame burns clean with a light, fruity smoke that adds a subtle aroma without overwhelming the dough. Cherry coals last about 45 minutes per load, which is typically enough for 6 to 8 pies before a reload.

Oak is the workhorse. Red oak produces 24.0 million BTU per cord, white oak 24.6 million. Both push dome temperatures to 850 to 950 Fahrenheit in roughly 45 minutes and hold there for the entire cooking window. Oak coals last 60 to 75 minutes on average, the longest of the three, which is why most Neapolitan pizzerias default to it. Smoke is heavier than cherry but still clean if moisture stays under 15 percent.

Ash sits in the middle at 23.6 million BTU per cord. It lights faster than oak, reaches 800 to 900 Fahrenheit in roughly 30 minutes, and burns with very low smoke. Coals last 50 to 55 minutes on average. Ash is a strong choice for the home pizza oven owner who wants quick startup and a clean flame.

One detail most guides miss: moisture content matters more than species. Oak at 25 percent moisture will underperform cherry at 15 percent every time. That is why every piece from Firewood Flex is kiln-dried to under 15 percent and USDA certified, removing the variability that wrecks home pizza nights. If you are running a regular pizza schedule and want predictable performance, order a Mega Bag or stock up through our wholesale firewood program. For first time buyers we offer same day firewood delivery across the Northeast. For full BTU values across 25 species, see our firewood BTU chart by species.

FAQ

What is the ideal moisture content for pizza oven firewood?
Pizza ovens perform best with firewood under 15 percent moisture content. At this level the wood ignites quickly, produces minimal smoke, and reaches the 700 to 950 Fahrenheit dome temperatures needed for Neapolitan and New York style pizza. Wood above 20 percent moisture wastes heat boiling off water, creates soot on the dome, and makes consistent cooking nearly impossible.

How long does it take to heat a pizza oven with kiln-dried hardwood?
On average, a standard home pizza oven heats from cold to 850 Fahrenheit dome temperature in 35 to 45 minutes using kiln-dried oak or ash. Cherry runs slightly slower, around 40 minutes. The fire typically needs 4 to 6 pieces during startup, then 1 to 2 pieces every 15 minutes to maintain cooking temperature once you start launching pies. Actual times depend on oven model and ambient conditions.

Can I mix different hardwood species in one pizza session?
Yes, and many experienced pizza makers prefer it. A common stack is oak for the base heat and coal bed, with cherry or ash added near the end for flame visibility and aroma. Avoid mixing in softwood or unknown species. Stick to USDA certified kiln-dried hardwood so you know what you are burning.

How much firewood does one pizza session use?
A typical 90 minute session that produces 8 to 10 pizzas uses roughly 8 to 12 pieces of kiln-dried hardwood, or about one third of a Mega Bag on average. Heavier oak loads use less wood overall because coals last longer. Cherry sessions go through wood faster but produce gentler heat for Roman style pies. Your real usage will vary with oven size and how hot you run it.

Do I need to split the firewood smaller for a pizza oven?
Most home pizza ovens accept pieces up to 14 inches long and 4 inches thick. Our Box product comes in compact pieces sized to fit standard ovens without resplitting. If you have a larger commercial oven, the Mega Bag pieces work without modification. For very small countertop ovens, you may need to halve pieces with a hatchet for the burn chamber.

Is Firewood Flex wood compatible with Ooni, Gozney, and Solo Stove ovens?
Yes. Our 1.33 cu ft Box pieces are sized for Ooni Karu 12, Karu 16, Karu 2 Pro, Gozney Roccbox, and Solo Stove Pi. Mega Bag pieces fit Ooni Karu 16 and most Gozney models without resplitting. For very small chambers, hatchet a few pieces in half before lighting.
