Baking Sourdough in a Regular Oven (No Fancy Equipment)

Let me address the elephant in the room: you do not need a Dutch oven to bake sourdough. I know that every sourdough blog, Instagram post, and YouTube video makes it look like a Le Creuset is mandatory equipment. It is not. For the first three years of my sourdough journey, I baked every single loaf on a sheet pan in a rental apartment oven that ran 30 degrees hot and had one working rack. Those loaves were excellent.

A Dutch oven is convenient. It traps steam beautifully and creates a consistent baking environment. But it is a shortcut, not a requirement. If you understand why steam matters and how to create it without a lidded pot, you can bake bread that is just as good.

Why Steam Matters (and What It Actually Does)

Steam during the first 15 to 20 minutes of baking does two things. First, it keeps the surface of the dough moist so it can continue expanding, this is what gives you oven spring, that dramatic puffing that happens when a cold loaf hits a hot oven. Second, it converts the starch on the surface into a thin, glossy gel that eventually sets into a crackly, shiny crust.

Without steam, the surface dries out immediately, sets into a thick shell, and the bread cannot expand properly. You end up with a dense loaf and a heavy crust. So the challenge when baking without a Dutch oven is creating enough steam in the first phase of baking.

Four Steam Methods That Actually Work

Method 1: Boiling Water in a Pan (Most Reliable)

Place an old cast iron skillet, broiler pan, or deep baking dish on the lowest oven rack while preheating. When you load your bread onto the rack above, carefully pour one cup of boiling water into the hot pan and close the oven door immediately. The water will hit the scorching pan and instantly create a burst of steam.

Method 2: Ice Cubes on a Hot Pan

Same setup as above, but throw a handful of ice cubes into the hot pan instead of water. The ice takes a moment longer to melt, which creates a more sustained release of steam over the first several minutes. Some bakers prefer this for better oven spring.

Method 3: Spray Bottle

Use a spray bottle filled with water. Spritz the oven walls and the surface of the bread immediately after loading, then again 2 minutes later, and once more at 5 minutes. Close the oven quickly each time to minimize heat loss. This method is simple but less effective than the pan methods because you lose heat every time you open the door.

Method 4: Roasting Pan Lid (Budget Dutch Oven)

Place your shaped loaf on a preheated baking stone or inverted sheet pan. Cover it with a large stainless steel bowl, a disposable aluminum roasting pan, or any oven-safe pot that can create a dome over the bread. This traps the steam the bread naturally releases and mimics a Dutch oven setup. Remove the cover after 20 minutes.

The Baking Process (Step by Step)

Preheat: Set your oven to 475°F (245°C) with whatever steam setup you are using. Preheat for 45 to 60 minutes.

Load: Score your loaf, slide it onto the hot baking surface, create steam using your chosen method, and close the oven door as fast as possible.

Steam phase (0-20 minutes): Leave the steam setup in place. Do not open the oven during this time.

Dry phase (20-40 minutes): After 20 minutes, remove the steam source (take out the water pan, remove the covering bowl, or simply stop spraying). Reduce the oven temperature to 450°F (230°C). Bake for another 20 to 25 minutes until the crust is deeply brown and the internal temperature reaches 205 to 210°F (96-99°C).

Cool: Remove from the oven and cool on a wire rack for at least one hour.

Expect Slightly Different Results

Sheet pan sourdough without a Dutch oven will look different from Dutch oven loaves. The shape will be broader and flatter (no walls containing the dough), the crust color may be slightly less even, and the scoring may not open as dramatically. But the crumb, the flavor, and the overall quality can be every bit as good.

Do not let equipment gatekeeping stop you from baking. A bag of flour, some water, salt, your starter, and a regular oven, that is all you need. For more about equipment options, check out my guide to Dutch oven alternatives and my essential kitchen tools guide.
