Baking Stone vs Baking Steel
Stones and steels both store heat for crisp bread and pizza bottoms. Compare heat transfer, preheat times, durability and which suits your oven and bakes.
A thick slab on the oven rack gives bread and pizza a hot surface to land on, so the bottom crust sets and browns quickly instead of waiting for thin bakeware to heat. Ceramic or cordierite stones have done this job in home kitchens for decades. Baking steels are newer: flat plates of carbon steel that move heat into dough faster.
Neither is simply better. A steel browns a pizza in a few minutes that would take noticeably longer on a stone, which is ideal in a home oven that tops out at 260 to 290°C (500 to 550°F). The same speed can scorch the bottom of a long-baked sourdough loaf. This guide compares the two so you can pick one, or understand when to use each.
Key points
- Steel transfers heat into dough faster than stone, so it browns pizza bottoms quickly at home oven temperatures.
- Stone is gentler and suits breads with long bakes, where a steel can over-darken the base.
- Preheat either one for at least 45 minutes, and up to an hour for thick steels or stones.
- Cordierite stones can crack from sudden temperature changes or wet dough; steel is nearly indestructible but heavy.
How heat moves from slab to dough
Both materials soak up heat during the preheat and give it back when cold dough lands on them. The difference is speed. Steel conducts heat many times faster than ceramic, so it pushes more energy into the dough in the first minutes. That is why the bottom of a pizza on steel can char lightly in four to six minutes.
A stone releases its heat more slowly. The crust browns more gradually, which can be an advantage for loaves that bake for 35 to 45 minutes and need the interior to finish before the base darkens too far.
Best uses for each
Think about what you bake most. Pizza-focused bakers, especially those making New York style or Neapolitan-inspired pies in a home oven, tend to prefer steel. Bakers who make free-form loaves, baguettes and pita several times a week often find a stone more forgiving.
- Steel: thin and medium pizza, flatbreads like lavash and manakish, quick-baked pita, searing under the broiler
- Stone: boules and batards baked directly on the deck, baguettes, rolls, longer-baked pizzas such as thicker Sicilian rounds
- Either: preheated base for a pie plate to help crisp the bottom crust
Thickness, size and weight
A 6 mm (¼ inch) steel is a common home size; it stores plenty of heat and weighs around 7 kg (about 15 pounds) at roughly 36 by 40 cm. Thicker steels hold more heat but are hard to lift and slower to preheat. Leave at least 2.5 cm (1 inch) of gap around the edges so air can circulate in the oven.
Stones are typically 1.5 to 2 cm thick. Thicker stones resist cracking better and recover heat faster between bakes. Rectangular slabs give more usable area than round ones for loaves and pizza peels.
Preheating and placement
Give either surface at least 45 minutes at full temperature; an oven thermometer will show the air is hot long before the slab is. An infrared thermometer pointed at the surface is the easiest way to know when it is ready.
For pizza, set the slab on an upper-middle rack and switch the broiler on for the last few minutes of preheat or during the bake to brown the top. For bread, a lower-middle rack gives the loaf room to rise and keeps the top from darkening too fast.
- Pizza on steel: rack about 20 cm (8 inches) below the broiler
- Bread on stone: rack in the lower third, steam source on a rack below
- Never put a cold stone into a very hot oven; heat it with the oven
Care and durability
Stones absorb moisture and oil. Scrape off burnt bits, brush them clean and let them dry; skip soap, which can soak in. Stains are harmless. A stone that gets wet, or meets a frozen pizza or wet dough, can crack when heated, so keep it dry and let it cool in the oven.
Steel is carbon steel that needs seasoning like a cast iron pan. Wipe it clean, dry it thoroughly and rub on a very thin film of neutral oil if rust spots appear. It will not crack, but it will dent a tile floor if dropped.
Common questions
- Can I leave a stone or steel in the oven all the time?
- Yes, as long as it does not block airflow. It can even smooth out temperature swings. Expect preheating to take longer for everything, and remove it when baking delicate items that need even air around the pan.
- Why are my pizza bottoms burning on the steel?
- The steel may be too close to the bottom element or preheated too hot for the dough. Move it up a rack, lower the oven slightly, or use a dough with less sugar, which browns more slowly.
- Is an inverted baking sheet a good substitute?
- It helps a little, since it gives a flat surface for sliding dough, but it is thin and stores little heat. Expect paler bottoms and longer bakes than with a stone or steel.
