Baking with a Dutch Oven or a Bowl over a Sheet Pan
Okay. Your dough is scored, your oven's heating, and now we get to the part where a lot of people think they need a fancy piece of equipment to make this work. You don't.
I want to say that clearly because it's one of my actual opinions and I'll stand on it: you do not need a Dutch oven to bake good sourdough. Nice to have, sure. Not required. I baked good loaves for months with a stainless steel bowl flipped upside down over a sheet pan before I ever owned a Dutch oven. Buy the flour and the scale first. Buy the toys later.
Why you need steam at all
Bread needs a burst of trapped steam in the first fifteen or twenty minutes of baking. That steam keeps the crust soft just long enough for the dough to rise fully before it sets up hard. Skip the steam and you get a crust that seals too early, and your oven spring gets choked off. Score's cut, the loaf's ready to open up, and the crust just won't let it.
A Dutch oven does this by trapping the moisture the dough itself is releasing. A bowl over a sheet pan does the same thing, just with parts you probably already own.
The Dutch oven method
- Preheat it with the oven. Put your empty Dutch oven, lid on, into the oven while it heats to 500°F. Give it a full 45 minutes to an hour once the oven hits temp. A cold pot is one of the more common ways people end up with a pale, sad crust. The pot needs to be genuinely hot before dough goes anywhere near it.
- Turn your dough out onto parchment. Flip your banneton or bowl over, dough lands on a piece of parchment paper on your counter or a peel. Score it now if you haven't already.
- Lower it in. Carefully — and I mean carefully, that pot is 500 degrees and so are its handles — lift the parchment by the edges and set the dough into the preheated Dutch oven. Lid on.
- Bake covered, then uncovered. 20 minutes with the lid on to hold the steam in. Then pull the lid off and bake another 20 to 25 minutes uncovered to let the crust actually color and crisp.
Use oven mitts, the real thick ones, not the thin decorative kitchen towel kind. That lid holds heat like nothing else in your kitchen and I've heard from more than one student who grabbed it wrong. Don't be that person.
The bowl-over-a-sheet-pan method
This is the one I want you comfortable with, because it costs you nothing extra.
- Preheat a sheet pan or baking stone in the oven at 500°F for the same 45 minutes to an hour.
- Get an oven-safe stainless steel or metal bowl big enough to cover your loaf with room to spare. Not glass — glass and thermal shock don't mix, and I don't want you finding that out the hard way.
- Slide your scored dough onto the hot pan using the parchment paper the same way you would for the Dutch oven.
- Cover the loaf with the bowl immediately. This is your steam trap. Bake covered for 20 minutes.
- Remove the bowl carefully — it will be hot, use your mitts — and bake another 20 to 25 minutes uncovered to finish the crust.
Same result, different equipment. I genuinely can't always tell my Dutch oven loaves from my bowl loaves once they're sliced. The crumb doesn't know what pan you used.
A word on our air and elevation
We're up around 4,600 feet here and our air is dry most of the year. That means your loaf can get a little more color, a little faster, than a recipe written by somebody baking at sea level in Seattle. Watch the crust after the 35-minute mark instead of trusting the clock exactly. If it's getting darker than you want, you can tent a piece of foil over the top for the last few minutes.
I learned this one the annoying way. My oven runs a little hot to begin with, and I got greedy chasing a deep, dark, bakery-style crust one afternoon and set my own smoke alarm off. I'd invited some folks from the gym over to try it and they got bread that ate more like jerky. I told them straight up, that one's on me, the oven runs hot and I pushed it too far. Nobody died. The bread just wasn't great.
A story about patience, which I don't have much of
My very first starter — long before any of this scoring and baking stuff mattered — turned pink around day five. Actual pink, like a light blush color on top. I about cried, because I thought I'd killed it and I still didn't understand what I was doing wrong. Turns out pink means throw the whole thing out and start clean, it's a mold situation, not a "keep feeding it and hope" situation.
Second attempt, I put the jar in the oven with just the oven light on for warmth and it finally took. Oh man, the relief. I bring that up here because the steam-baking step is a little like that — you can't rush the setup and expect the result to fix itself. The pot has to actually be hot. The dough has to actually get its steam. Skipping steps doesn't save you time, it just gives you a different problem later.
Before next time
Bring whatever you're baking in — Dutch oven, stainless bowl, whatever you've got — and we'll do a real bake in class so you can see the steam do its job with your own eyes.
