Countertop pizza ovens: what 400°C actually buys

A domestic oven tops out around 250°C. Neapolitan pizza wants 430°C. That gap is the entire product category.

Why your oven cannot do it

A pizza is cooked by conduction from below and radiant heat from above, in about ninety seconds. At 250°C that same base takes eight to ten minutes — long enough for the topping to dry out and the dough to bake rather than puff.

The leopard-spotted, airy crust people are chasing is a time effect, and you only get the time by having the temperature.

What to look for

• Peak stone temperature, not air temperature. The stone cooks the base. 350°C+ is where results change noticeably.
• Recovery time. The stone gives up heat to the first pizza. A good oven is back up in two or three minutes; a poor one takes ten, so the second pizza is worse than the first.
• Stone thickness. Thicker holds more heat and recovers better. It also takes longer to preheat.
• Top and bottom elements that run independently, so you can brown the top without burning the base.

The practical limits

These are single-purpose machines. They make excellent pizza and flatbread and essentially nothing else, and they take up permanent worktop space to do it. That is a fair trade if you make pizza most weeks and a poor one if you make it twice a year.

They also need 15 to 20 minutes of preheat. It is not an appliance for a spontaneous weeknight.

Getting a decent result

• Preheat longer than you think. Most disappointing first pizzas are underheated stones.
• Less topping. Ninety seconds will not cook a heavily loaded pizza — the base burns while the middle stays wet.
• Semolina, not flour, on the peel. Flour scorches at these temperatures and tastes bitter.
• Turn it. Every oven has a hot side. A half-turn at forty-five seconds is the difference between even and charred.
