Turn Your Oven Into a Proofing Oven

by Daisy on 01/11/2009

Thank you for visiting Little House in the Suburbs. If you like what you see, please SUBSCRIBE.

If you have ever worked in a commercial kitchen, you may have had experience with a proofing oven. It’s simply a big metal cabinet with racks for trays of dough (rolls, doughnuts, loaves of bread).

It maintains a warm, moist environment for the yeast to prosper and create perfectly-risen baked goods. Few of us are going to have one of those in our kitchens, but we improvise. I have a sister-in-law in whose rear car window can regularly be seen a bowl of pizza dough. Sunny windows, heating vents, & radiators are often made to do double-duty in this way.

I use my oven. This is for ovens with no pilot light–I have heard those make the ovens too hot.

1. Set up your oven racks. You need a rack for the pan of dough in the upper portion of your oven. Be sure to allow enough space above the pan for the dough to rise. You need a rack below the pan of dough for a medium-sized pan of boiling water. Alternately you may be able to set the pan on the bottom floor of the oven provided the heating element is not in the way.
2. Place the dough on its appointed rack in a cold oven. Boil a pan of water and place on the rack below it. Close the door of the oven and turn on the heat to 400 degrees F. for exactly one minute. Time this exactly! Don’t forget and go off to do something else! Turn off the heat and don’t open the door. Leave your dough for the amount of time recommended in your recipe.

You will not need or want to cover your dough under these conditions. It will be sufficiently humid inside the oven from the boiled water to obviate the need for a cover. (And of course plastic wrap would melt when you turned the heat on. A towel might scorch.) Just don’t cover it.

No special equipment required. And you’ll never forget and drive around town with a pan of Parkerhouse rolls sliding around in the backseat.

I guess it depends on how big the baking project is, but for a loaf or two I just use the built-in microwave over my stove with its light turned on (you know, the bulb that lights the cooktop). It stays warm, the light bulb maintains a low, steady heat, and there are no drafts or drying out. I think of it as a mother hen sitting on my dough.

Just a thought. 🙂

Well, I’m disappointed. I’ve been trying to find that perfect proofing method for a long time. My husband is a bit tired of bricks of bread. The first rise goes well, and I can do that on top of a warming oven. I tried your method for the second rise, and…well, it’s been a couple of hours and it’s still not risen above the top of the loaf pan. It’s in a glass pan, and I can see lots of air bubbles, which I think is good, but I’m not sure. I used a 100% whole wheat recipe on King Arthur flour recipe. I suspect the heat is too high, but I followed your instructions. Any help would be appreciated.

Daisy April 7, 2015 at 10:11 pm

Claudia–Sorry about your loaf. I’ve never had dough take that long to rise, so (as by this time you’ve discovered one way or another) it’s probably not going to. As to troubleshooting, I imagine you’ve tried everything: testing your yeast to make sure it’s viable, making sure the liquid wasn’t so hot it killed off the yeast, checking the cupboards for mischievous pixies, etc. The only other thing I can possibly imagine would be if the first rise lasted so long it exhausted the yeast and it was too pooped to pop the second time around; try shorter first rises maybe? Otherwise blame the pixies.

Claudia April 8, 2015 at 7:28 am

You may be right about the first rise…I let it go for 2 hrs…the recipe said 1-2 hrs, depending on the warmth of my kitchen. I didn’t know letting it go long the first time would affect the second rise. I’ll try it again. Thanks.

Claudia April 8, 2015 at 12:14 pm

Update. I used a container for the first rise that had measurements on it, so I could tell if it was doubled in size. My recipe says to leave it for 1-2 hrs, so I set the timer for 1 hour. I felt that was safe, right? Well, it went more than double in just that one hour and now I have the same result as I did yesterday…a pooped out, flat dough. So, I’ll try it again and set it for 15 minute increments. If I can catch it at just double or even a little less, the second rise should be wonderful. AND…my husband had a question….why not do the first rise in the loaf pan, and, after the rise time is over and it’s high and puffy, just bake it at that time? I told him I figured it was because it’s too airy and puffy…punching it down and letting it rise again makes for a dough that is not all air bubbles…am I right?

Daisy April 8, 2015 at 3:49 pm

Claudia–You’re right about the bubbles, a second rise is said to produce a finer crumb and eliminate the huge air spaces. Mainly, though, it makes the bread taste better as the fermentation process produces more alcohol and something called maltose which improves flavor, texture, and helps with browning. You can certainly try a one-rise bread and see how you like it. I’d be interested to see what happens. Some roll recipes I know only require one rise.

Claudia April 9, 2015 at 8:52 am

Two questions…what is the best humidity for proofing bread? When you say “a pan of boiling water”, what size pan do you use? A loaf pan? A 6-quart pan? Thank you!

Daisy April 9, 2015 at 1:35 pm

Claudia–The exact humidity isn’t terribly crucial–it is useful so you don’t have to cover the dough with plastic wrap or a towel to keep the surface of the dough from drying out (mine often sticks to the dough and makes a mess/causes the dough to fall) and forming a crust which would interfere with the rise. I use a small saucepan; it probably holds about a quart and a half. Sometimes smaller. The oven is a finite, smallish space, so it doesn’t take much.

Close the door of the oven and turn on the heat to 400 degrees F. for exactly one minute. Time this exactly!

So my oven takes several minutes to get to 4oo. Does that time all count in the 1 minute or do you just count the warming up to 400 in that 1st minute? Does that make sense? Just trying to clarify so I don’t goof it up.

Thank you!

Daisy May 5, 2015 at 1:02 pm

Julie–Good question. The timing starts from the time you turn the knob, not from the time the oven reaches temp. You don’t want to get to 400 deg., just knock the chill off.

Heather May 12, 2015 at 10:38 am

There are one rise breads out there, and I will use them when I’m in a time pinch but it’s a compromise on flavor and on the crumb if the recipes isn’t intended for a single rise.

I usually proof in my oven with the light on but I’m excited to try this method.

Phil July 26, 2015 at 12:31 am

1. There’s nothing magic about the 400 deg setting during the minute: any setting that cannot be reached in one minute will do, and the result will be the same. Ovens operate at full power until the target temperature is reached, then shut off until the temperature drops below a low threshold then cycles on at full power until the target is reached again, etc.
2. Maltose, also called “malt sugar”, is a sugar that is produced by the breakdown of starch in the grain by enzymes that are produced by the endosperm of the grain when it sprouts. The process of causing grain to sprout, thus producing the enzymes, the drying and roasting the grain, thus killing the sprouts, is called “malting”, and the product that results is called “malt” or “malted grain”, which is the used to make beer and whiskey. I suspect that there may be some low level of the same enzymes in unmalted grain (and flour) that could convert some of the starch. These enzymes are activated by moisture, and are more active at higher temperatures up to about 158 deg.

Phil July 26, 2015 at 12:41 am

3. Yeast mostly eats sugars, including maltose, and mostly produces CO2 and alcohol.
4. Maltose will lend a sweeter and “malty” flavor to the bread, and will cause the bread to brown easier, and at lower temperature.

You might also check which type of yeast you are using. Instant yeast doesn’t need to be dissolved before adding to the dry ingredients and it doesn’t need two risings. In place of the first rise you would knead the dough and let it rest for 10 minutes. Continue with to follow your recipe with instructions after the first rising. I learned this from the King Arthur website.

Marilyn November 13, 2015 at 3:25 pm

So when you say set to 400 degrees for exactly one minute, you mean that the oven doesn’t actually reach 400 degrees. The one minute period is the oven warming up to get to 400 degress, correct?

Thank you just saved me 200 dollars on a proofer I’ve been avoiding to buy. So it was try this or spend ugh! Well it actually worked and it seems easy to do but people appear to make others nervous and harder when reading some of these comments. Well anyway thank you!
And to Phil … NOOOOOOOOOOOOOOOOOOOObody cares! Plus you are speaking beer language acting like an expert well I saw the beer website you got this plagiarism from that you entered here, right down to the ”Thus”. You’re so moded lol!

Jenn January 17, 2016 at 12:00 pm

I use my oven but set it on the lowest setting, 170 degrees, with a big pot of water on the bottom and proof for 45-60 min, depending on the weather. Works great!

Ray Flacke August 25, 2016 at 5:34 am

Hi Daisy, when you say 400 degrees, you don’t say preheat, but would that be too much to put in and then turn off? Thanks Ray

Daisy August 25, 2016 at 5:39 am

Ray Flacke–Right, don’t preheat it, literally just turn it on for one minute and then turn it off. Easy as pie.

L. Archer September 1, 2016 at 11:44 am

Or, you could use that drawer under the oven to proof your breads. That is what it is designed for, not for storage of lids and pans.

Lindsay Marshall September 5, 2016 at 2:19 pm

Claudia, the use of whole grain flour also affects the raise of bread. Whole grain doesn’t raise as well as more processed flours. Right Daisy?

Daisy September 5, 2016 at 3:07 pm

Lindsay–Yes, that’s true.
