Baking Bread with Steam in Your Home Oven

Steam burns hurt. Like really, really hurt. The small mark on my left forearm begs the question daily: Maurizio, was it worth it? But before we talk about my new baking badge of honor, let’s concentrate on overcoming the challenges of baking good bread at home. While many of these challenges present themselves early in the two-day process (fermentation, flour selection, mixing, shaping, and so on), there is that crucial component at the end of this ordered procession: baking bread with steam in your home oven.

For your bread to rise to its potential, that outer, taut skin on your loaf needs to be able to expand and stretch before hardening off. Steam in the oven and subsequently on the surface of your loaves helps keep that skin pliable and stretchy during baking. If your dough dries and bakes too quickly on the exterior, it can harden off before it rises to its full potential (and you may not see a satisfying gringe, either).

So how can we get enough steam in the oven to keep those loaves rising? There are indeed methods abound, and each person has a different approach, but arguably the most popular choice at the moment, and the one I started with, is baking bread in a Dutch oven (see my guide on how to bake bread in a Dutch oven if you're not familiar). However, there comes a time when you might want to bake two (or more) loaves at a time, or perhaps your loaves are scaled more substantial than your Dutch oven can comfortably hold. An alternative is to bake directly on stones and generate sufficient steam in your home oven by some other clever means.

Professional baking ovens have steam on tap. Press a button, and a wave of steam sprays over the decks of newly loaded dough (however, there are always challenges, no matter what oven you use). Now there are home ovens that are “steam ovens,” but the ones I’ve looked at are incredibly small. You might be able to fit two loaves, but I could also fit two Dutch ovens in my current home oven; no advantage there. Some other alternatives can’t inject steam at a button press, but they are sealed to trap steam and have a method for generating steam. These look very promising but are on the expensive side.

Since most of us bakers out there do not have one of these fancy ovens, we have to make do—read on to learn how baking bread with steam in your home oven can be a straightforward process.

Tools for Steaming Home Oven

We first need to have the right set of tools for the job. Let’s go over a few more additions to our home-baking arsenal:

Lava rocks

The first is a cast-iron pan filled with lava rocks1. Lava rocks are a primo choice because they get extremely hot, don’t break down easily, and have tons of jagged sides and crevices for an incredible increase in surface area. What’s the big deal about surface area? As cooler water comes into contact with a blisteringly hot surface, it instantly turns to steam. The more hot surface area you have, the more steam you generate. I found these lava rocks, specifically made for home BBQ grills, and they have turned out to be a perfect choice. They come in a fairly large bag, and I am still on my first handful — I probably have lava rocks for life.

Roasting pan

The second component is the heavy-duty stainless steel pan I use to hold the lava rocks. This stainless steel pan is great for a few reasons: it's super thick-walled, retains heat well, and holds up to abuse.

Rectangular baking pan

The last component is an old rectangular baking pan with small dish towels rolled tightly. I use an old pan around the kitchen and roll up three small towels in the center. The more towels you add, the more steam you’ll generate. I use cheap, clean towels as these will eventually get scorched and need replacing.

Rolled up towels saturated with water

Ten to twenty minutes before you start baking, you will boil some water and pour it over the towels in the rectangular pan, so they are fully drenched and steaming. You will then place this pan with towels back inside your oven. This pan will saturate the interior with steam before you even splash water on the lava rocks and will continue to do so well into the bake.

Optional Hand Spritzer

The final item is optional. A stainless steel hand spray bottle I use to spray in a bit more steam just before closing the oven door. I like to have the option to spray in a bit more steam if I feel it is warranted. Additionally, you could use this after 5-10 minutes into baking to quickly saturate the oven inside one more time. Some bakers, like Jeffrey Hamelman in Bread, recommend this second round of steaming in a home oven.

Not many new tools are needed, and if you think about it over the long run, you will probably save money as now we can bake 2-4 loaves at a time — no more wasting all that space in the hot oven. How do we do this now that we have the tool requirements squared away?

Baking Steam Method

The following does take a bit of practice. First, ensure you get all your tools ready and within reach; this is a rather hectic process, and you want to do it almost without thought — muscle memory. The longer your oven door is open, the more heat will escape. Your thick baking stones or a baking steel (which is also awesome for sourdough pizza!) will help offset some of the loss, but you still want to act quickly.

Below is a quick visual showing where I have my pans, where the loaded dough goes, and where my baking stones are.

Now that we have a list of what things we need, where items will be placed, and why, let’s get to the actual method (with the animated version below!).

Home oven steaming method

  1. An hour before baking, turn on your oven (preheat)
  2. 10-20 minutes before loading your bread, boil water, pour over the towels in your rectangular baking pan, fully saturate them, and place them in the back corner of your oven
  3. 10-20 minutes after loading the pan, put each mass of dough on a separate piece of parchment paper
  4. Place the dough and parchment underneath on a pizza peel
  5. Score dough
  6. Open the oven and slide the dough (with parchment) onto baking stones
  7. Quickly lay a towel down on the oven door glass (optional, you can see me doing this below) 2
  8. Carefully toss 1 cup of ice into your cast iron pan with lava rocks
  9. Quickly spray loaves a bit with a hand spritzer (optional)
  10. Close the oven door and watch your dough rise
  11. 20 minutes later, remove both steaming pans (careful these are extremely hot) to stop steaming
  12. Bake as usual until done

Whew, that’s it! Here is the whole process (minus the preheating and drenching of towels) in one trendy baking-with-steam GIF:

Why do we use two sheets of parchment paper for our dough? When you use two sheets, you can adjust the space between the loaves as they bake, if necessary. One of the worst things to happen is when the dough expands and joins with another loaf; this reduces the overall rise of both loaves. If you notice the loaves start to get a bit close as they rise, quickly slide them apart.

After 20 minutes of baking, we remove the cast iron and rectangular baking pan, so no more steam is generated, allowing your loaves to crisp up and harden off.

Caution: Please be careful with this method: if you drop too much cold water on your oven door, you might crack the glass. I have never had this happen to me, but I know of at least one baker who had this issue. Be sure to keep the water off the glass.

Another approach to baking bread with steam

Baking bread in a sealed post is possibly the easiest method of baking bread with steam at home. You place your dough in a preheated pot, close the lid, and put that in your oven.

That method works incredibly well, but the drawback is you can only bake round loaves this way. You're limited to the realm of round pots.

If you'd like to keep using a Dutch oven, see my post on how to avoid burning your loaves →


I like this method for baking bread with steam in my home oven because it allows me to cook two large loaves of bread at a time. I plan to bake four loaves at a time, and this will let me do that with no problem. Baking with a Dutch oven (or combo cooker) works exceptionally well, and I might still use that method if doing only a single loaf or a highly hydrated one (the pan will help keep the dough together). Still, I find myself using this new method more and more. The results have come out smashingly.

Small steam burns: worth it (as you can see below). 3

If you try this method, I’d love to see it! Tag @maurizio on Instagram and hashtag your photo #theperfectloaf so I can take a look!

  1. Other materials will work just as well here: (clean) nuts and bolts, a metal chain, or any other heat-retentive material that will increase surface area. Keep in mind whatever the material it needs to be able to withstand around 525ºF and water splashed onto it.

  2. I’ve read that cold water dropped onto a hot oven glass door will shatter the glass, thus the towel. I have dropped some water on the oven door without any ill effect, but I do this to be safe.

  3. … and you don’t have to get burned, be careful!
