Do you actually have to preheat the Dutch oven?

Every sourdough method online says the same thing: get the pot screaming hot, empty, for an hour, then wrestle the dough into it without burning your forearms. It turns out that step is optional — and skipping it solves a problem most bakers do not know they have.

Somebody actually tested this

King Arthur Baking ran both methods side by side: one loaf into a preheated pot, one placed in a cold Dutch oven that went into a cold oven and came up to temperature with the bread inside. The cold-start loaf browned properly, the slashes opened, and the interior was what they called a remarkably similar crumb structure. When both loaves were baked in the same style of pot, they came out almost exactly the same height.

Neither method…is right or wrong, nor is one decidedly “better” than the other. We encourage you to use the approach that works best with your equipment and taste preferences. King Arthur Baking, Baking in a cold Dutch oven

Their one real caveat was about shape rather than heat: a pot with a smaller base gives a taller loaf, because the dough has less room to spread before the crust sets.

Why this matters more if your pot is enameled

Preheating an empty enameled pot is the single thing enamel likes least. Dry heat with nothing inside to absorb it puts the glass coating under stress, and it is the usual reason a pot that should have lasted decades develops a chip in its first year. Cold-starting removes that step completely.

It also removes the part of the process most likely to hurt you. Lowering slack dough into a 500°F cast iron pot is genuinely the most dangerous thing in home baking, and it is the reason a lot of people try sourdough twice and stop.

What to look for in a pot for bread

Rated to at least 450°F — including the lid knob This is the specification people miss. Plenty of pots are oven-safe while their handle or knob is rated far lower. Check the knob separately; it is the part that fails.
A lid that genuinely seals Steam is the entire mechanism. The dough releases its own moisture, the lid traps it, and that trapped steam keeps the crust soft long enough for the loaf to expand. A loose lid is just an open oven.
Five to six quarts, round Big enough for a standard boule, small enough that the dough does not pancake. Oval pots make oval loaves, which is fine, but round is the default for a reason.
Loop handles you can hold in bulky mitts You are moving a hot, heavy, covered pot with a live loaf inside it. This is a safety feature.

The one that meets all four: the Lodge Essential Enamel Cast Iron Dutch Oven, 6 quart.

Rated to 500°F, lid included, with a moisture-sealing lid and wide loop handles. Lodge lists bread baking as a primary use for this pot rather than an afterthought, which is not true of every enameled Dutch oven in the same range. Round, six quarts, and cast by a company that has been pouring iron in Tennessee since 1896.

The honest limits. A six-quart base is wider than a dedicated bread pot, so a slack, high-hydration dough will spread more than it would in a narrow purpose-built vessel — exactly the effect King Arthur described. And if after all this you still want to preheat empty, buy bare cast iron instead: unenameled iron does not care, and enamel does. This pot is the right answer for cold-start baking and for everything else you cook in it, which is the point of owning one pot.
