Pizza oven heat-up time depends on the fuel and the oven: a portable gas oven preheats in about 15–20 minutes, a pellet oven takes about 18–20 minutes to reach a hot stone (about 887°F / 475°C on Big Horn’s 12-inch), and a large brick or wood oven can take one to two hours. The number that matters is the stone’s temperature, not the air — and the stone must fully soak before the first launch. This guide covers the times by fuel, the variables, and how to preheat right.
These are general pizza oven preheat guidelines; your oven’s manual and weather change the exact time.
What actually matters for this decision
- Stone, not air. The stone bakes the base; preheat until it holds the target, checked with a thermometer.
- Fuel type. Gas preheats fastest, pellet needs a fire to settle, wood and brick take the longest.
- Oven size. A larger stone or chamber soaks more heat and takes longer.
- Conditions. Cold, windy weather extends the preheat.
Understanding the preheat before you decide
Heat-up time is about when the stone, not the air, reaches baking temperature. Gas ovens light and reach about 750–850°F in 15–20 minutes; pellet ovens need the fire to build and the stone to soak — about 18–20 minutes to about 887°F on the 12-inch Big Horn model; wood and brick ovens can take one to two hours because they soak a large thermal mass. A half-hot stone steams the base, so the preheat is the difference between a crisp and a pale pizza.
Heat-up times by type
| Oven type | Typical preheat | Target stone |
|---|---|---|
| Portable gas | 15–20 min | 750–850°F |
| Pellet (12-in) | 18–20 min | About 887°F / 475°C |
| Wood / masonry | 1–2 hours | High heat, fully soaked |
| Home oven | 20–30 min | As hot as it goes, stone inside |
Matching the choice to your situation
For a weekday bake, a portable gas or pellet oven’s 15–20 minute preheat is practical — start it, stretch the dough, and the stone is ready. For a wood or masonry oven, plan the preheat into the day — it is a ritual, not a short wait. If you want less preheat, a gas or pellet oven wins; if you want the wood-fired bake, you accept the build time. Match the preheat to your schedule and the fuel to the flavor you want.
What the experts look for
Experienced bakers preheat the stone, not the timer: they start the oven, wait the full preheat, and confirm the stone with an infrared thermometer aimed at the center before the first launch. They also adjust for weather — a cold or windy day adds minutes — and let the stone recover between pies. The reliable method is a full preheat and a thermometer check, not a countdown.
Common mistakes and how to avoid them
- Judging by the air. The stone decides the base; check it with a thermometer.
- Launching early. A half-soaked stone steams the base; wait for the full preheat.
- Rushing on a cold day. Cold and wind add minutes; give the oven more preheat.
- Not letting the stone recover. Between pies, return the stone to temperature.
- Trusting a fixed timer. Preheat varies with fuel, size, and weather; the thermometer is the referee.
Realistic expectations and results
A portable gas or pellet pizza oven’s heat-up is a manageable 15–20 minutes; a wood oven is a longer commitment. Expect the stone, not the air, to be the readiness check, and plan the preheat into the cook. The payoff is a crisp base and a 60–90 second bake, which is exactly what the preheat is for.
The takeaway in one paragraph
Heat-up time depends on the fuel — about 15–20 minutes for a portable gas oven, 18–20 minutes for a 12-inch pellet oven, and one to two hours for wood or masonry — and the readiness signal is the stone, not the air. Fully preheat the stone, confirm it with an infrared thermometer, and adjust for weather. Match the preheat to your schedule and the fuel to the flavor, and the oven is ready when you are.

FAQ
How long should I heat up a pizza oven at 400?
At 400°F — a home-oven temperature, not a high-heat pizza oven — preheat about 20–30 minutes with a pizza stone inside so the stone soaks. For a dedicated pizza oven, preheat to the market brick’s target (750–887°F+) rather than 400°F.
How long for a pizza at 350?
At 350°F a pizza bakes slowly with a softer crust — not the Neapolitan style — and the time depends on thickness. Use a stone or steel and check doneness; 350°F suits thicker or stuffed pies that need a longer bake.
How long do I reheat pizza at 350 degrees?
Reheat pizza at 350°F for about 5–8 minutes on a stone or directly on the rack until the cheese melts and the crust crisps; check it rather than trusting a fixed timer.
How long do I cook pizza at 450 degrees?
At 450°F in a home oven with a preheated stone, a standard pizza bakes in about 10–15 minutes; a dedicated high-heat pizza oven bakes in 60–90 seconds at 750–887°F. Match the time to the temperature.
