One gal mentioned that her husband was a firefighter and that leaving a stockpot simmering overnight or while they were out of the house was completely out of the question.
If leaving a stockpot on the stove on low heat, continuously simmering for anywhere from 6-50 hours depending on the types of bone broth is in any way a concern, you have a couple of options. Option number one is to make fish stock. Fish stock is very fast and you can make a quick gallon of it in only 4 hours. Alternatively, you can make bonito broth which takes only a few minutes.
Option number two is to use the Cumulative Time approach for making stock. Monica Corrado, MA CNC and author of the blog Simply Being Well introduced me to this concept recently when I sat in on one of her amazing cooking classes at the Fourfold Path to Healing Conference in Baltimore.
The Cumulative Time approach for making stock simply means that the required simmering time for a particular type of stock can either be continuous or broken up into sections that equal the total required duration when added together.
The catch is that each time you start to heat the stock again, you must bring it to a boil, skim the foam, and lower to a simmer. You can’t just bring it to a quick simmer after it’s been off the heat for awhile.
Making Stock: What to Do When the Heat is Turned Off
The great news is that there is no need to move the stockpot in and out of the refrigerator between simmering sessions on the stove. The reason is that it would take a stockpot 4 hours or more at room temperature before any pathogens started to grow.
Anyone who is experienced making stock knows that a stockpot with the lid left on will never get to room temperature for 4 hours even if you leave it on the stove for 12 full hours with the heat off.
If the length of time required to make chicken or beef broth has been intimidating to you in the past, try the Cumulative Time approach! Just be sure to keep a little notebook in the kitchen so that you can log the total amount of time the stock has simmered so that you ensure a quality, gelatin rich broth when you are finished.
Making stock safely couldn’t be easier when using the cumulative time approach!

That’s exactly what I do. I wouldn’t feel comfortable leaving the stove on overnight or when I’m out. So I just turn it off, leave the covered pot out, and re-start when I’m ready. Works great.
I use my crockpot for everything. I turn it off at night sometimes because I don’t want whatever I am cooking to tun to mush. The older ones cook at a lower temperature than the newer models. Don’t know when this change was made, I was just told this by my brother-in-law. It is good to know that turning it off at night is safe for the food. Now I am ready to try the broth!
Thank you so much, cooking the stock long enough has always been a problem. This is a perfect solution:)
I’m thinking of making a solar oven to make stock in during the summer. Does anyone have experience with this? It would be like the cumulative time method, so I guess I would have to bring it inside to boil it on the stove every morning. I wonder if I closed the oven at night if it would stay hot enough that I wouldn’t need to reboil it…
I have used my sun oven, and it works great! Only problem is that it’s hard to control the heat, and it can get way too hot so you don’t have the “smiling,” barely simmering temp you want. You can just leave the door unlatched, though, or prop it open a bit. I leave it all the way open to dry almonds etc.
My Hamilton-Beach crock pot is too hot on “low” but too cool on “warm.” I’ll experiment w/ putting the lid a bit sideways.
The oven really is a great solution in winter. I wonder whether the firefighters would approve of the oven being on super low all night. Is this much different from having the heater on low all night? The liquid will not boil off if the temp is very low and if you are using a traditional stock pot.
Where I live, cooking inside in summer is not practical. So the sun oven is great, or I can set the crockpot outside (never overnight though!!! Can’t chance an unexpected rain!).
Every week we cook two chickens with salt pepper thyme and a couple bay leaves in the crock during the day. That night we have fabulous roasted chicken w plenty of leftovers for lunches or chicken tacos. After dinner we toss in veg and 4-6cups water and cook it on low overnight. In the morning we have lots of yummy stock that held beautifully!
I’ve tried the crockpot – my settings are high (4 hrs), medium (6 hrs), low (8 hrs), and warm (10 hrs). Low keeps foods at a steady boil, with warm there are no signs of bubbles. I have searched and searched for a crockpot that allows you to set temperatures but have never found one. I think I heard it has something to do with safety. But I wonder why it should be different than an oven.
@ Shirley J: I’ve had trouble with crock pots, too, in regard to temperatures. Mine (I have three) get so hot I can fry chicken in them! They are not made the same as when they first arrived on the market back in the 1970’s or whenever. They were actually better back then. Everyone is hoarding the old ones!
My DH was a firefighter (now retired) but the difference between a crock pot and a stove is the voltage. Anything which plugs into a wall is a potential fire hazard, of course, but the small appliances are where he saw the most damage over the years from kitchen fires. For years I have kept all of my small, counter-top appliances unplugged except when in use. I keep my toaster unplugged and covered with a tea towel because it’s right next to my kitchen window and I DO NOT like toasted bugs! Also, my DH literally preaches to women never to use the plug-in air freshners (like Glade and a few others) and he almost went bonkers when they introduced a line of mentholy / Vicks-y type scented plug-ins to use in kid’s rooms! He just stood here in front of the TV and hollered “no, no, no!! those are dangerous”.
Until and unless you’ve experienced the tragedy of a house fire, it’s hard to understand the power of electricity. We have some friends who recently lost their son to electrocution as he was installing a new light fixture. Electricity is nothing to mess with.
So I am one of those people who would not leave a crock-pot or a stove on overnight or when I’m away from the house, so it’s comforting to hear that what I’ve been doing with my broth making for the past 40+ years is ok! I always just leave it on the stove and restart the next day. Sure wish they still made stoves with the old-fashioned deep well / soup well in the back. My gramma had one of those and she kept soups and broths going constantly, but her stove was wood-fired. I DON’T miss that part!
If you are not home during the weekdays, start a smaller batch on a Friday evening and let ‘er rip until Sunday evening, with nights off. I just made some ham stock over this past weekend because I had a ham bone and a ham hock waiting to perform. 🙂 Small batch is the key word when you have only a short amount of time to work with.
Sarah,
I sometimes make my stock in a crock. This time I added about 15 carrots (to use for others meals w/the chicken). My soup turned out a very dark brownish/orange tea color almost. I think its from the carrots. Would this be ok? The soup has a good taste.
Do you ever have a problem with the liquid becoming too low? I was wondering if you have to add water at any point and if so does that dilute the broth or hinder the gel?
So, I think you answered this in your post above, but it is safe to leave stock on the stove top for longer than two hours? I have small children so I’m always worried of food poisoning them. I try to get my stock in the fridge right away after cooking, but then I heard that you have to let food cool before putting in the fridge. I’m confused can you help me with this?
Or come into either GRUB locations and pic up some high quality freshly made stock today!
Thank you Sarah! I have been wondering about this. I don’t so much mind making stock on my electric stove (although after seeing your simmer the other day, I think I may keep it too low overnight), but at some stage I could be moving into a house with a gas stove, and I know there’s no way I could sleep with a flame burning all night!! So I’ve been worried about what I would do if that ever comes (although it may not happen for a couple of years!!).
I also kind of like the idea of leaving a crockpot outside to make stock!! It would also feel a bit safer that way. Unfortunately, my crockpot doesn’t seem quite big enough… I have used it before (before I got a good stock pot), but I really had to squeeze the ingredients in!
Hi Fiona, Even my two crockpots combined can’t make the all the stock I need. I invested in a Le Creuset 12 qt. Stainless Steel stockpot–got it for a great price at one their outlet stores. I use a metal flame tamer under mine on my gas stove and start in the day time whenever I get around to it and leave it on the flame tamer on very low all night. As long as you use a flame tamer and don’t turn your gas flame down so low that it is flickering, you won’t have any problem.
In addition, I found a great Rubbermaid strainer that it curved on the edges (no bar to rest it on the pot side) and it makes a fabulous scouper/strainer when you are making large quantities of stock. For instance, I cannot pick up my 12 qt. stockpost and strain the stock into something else. So, I use the scouper/strainer and scoop out most of the bones, etc and the weight of the pot them becomes manageable for me. good luck!

I have been enjoying this blog but cannot seem to find any sort of “about the author” page.
This is a bit frustrating. Does anyone know if there is a page dedicated to telling me who it is I am reading and perhaps the goal or concept of this blog?
I don’t even know how to properly share it as I can’t say what precisely I am sharing beyond “a blog which seems to be focused on healthy concepts by a possibly anonymous person”… Not much a of a selling point that..
Am I missing an obvious link?
Click “Sarah” at the top of the page.
OH!
Thank you. I didn’t realize I could “click” the words on the purple bar. I thought they just opened the drop menus. Hence my frustration. I saw her name but could only see options for adverts etc. in the dropped portion.
Very interesting.
I always just let mine simmer continually as it just doesn’t worry me. A lot of my friends and family tell me I am mad though, so this approach may be the key to get them to finally start making real stock!
I started my first ever pot of chicken stock on the stove yesterday (bones from roasted whole chicken plus the neck, and other parts they stuff inside). My husband refused to allow me to leave it on the stove overnight, even though we have a Corning cook top (he is a volunteer fire police and has been to too many stove fires caused by unattended pots). So, I transferred it to my crock pot. It only has 3 settings, High, low, and warm. The high seems to boil too much, with the low there is no movement in the broth so I am now adjusting it between high and low hoping to find just the right “roll” as Sarah showed in her video. My house sure smells yummy and my stomach has been growling — hoping my first attempt has good gel results! 🙂
When making beef stock how do you know when precisely that it is done? What is it I’m supposed to be looking for? I was already doing the cumulative time approach when making stock. (I have firefighters in my family, too) (I’ve only made one batch of beef and one batch of chicken) The chicken didn’t gel. : ( Does that mean its no good?
I brought a slow cooker with a countdown timer (10 hours). But there are slow cookers where you can program the time to turn on and to shut off. I’m away at work for 10 hours and I get home just in time for my slow cooker to turn off. I just punch in another 10 hours or whatever # of hours you need to complete your stock.
Like Sybil and Joyce I make my stock in LARGE quantities. My family loves lots of soups and we all enjoy a cup of warm salted broth before bed. I keep my bones in the freezer until I have enough to fill my giant stock pot. We never throw a bone away, just toss it in the freezer. I also combine bones from chicken, beef, turkey or whatever. The flavors deliciously mingle and it is much easier than trying to keep them separate. I also toss in chicken heads, gizzards, necks and feet. My favorite bones from the cow are the shanks (calf bone) because they make wonderful gelatin. Here in Washington State we have cold enough months 6-7 months of the year that we make most of our stock on the woodstove. This is a wonderful energy saver since the woodstove would be going anyway. I have an assortment of cast iron trivets of various heights so I can set my stock where I need it to get the right simmer.
I also freeze my stock in glass jars. No need to risk chemicals leaching from the plastic into your lovely stock. We use 1/2 gallon canning jars that you can buy at the local hardware store. I just leave a good 2″ of head space for it to expand as it freezes. Homemade bone stocks are a foundational part of my family’s diet.
What is the max time you leave it in the fridge. -and also the max time for thawing before
the timing and temps are difficult to navigate. When would you throw it away?
I might have missed it in the comments or mis-read the post, but I wanted to clarify something. The temperature danger zone is between 40 and 140 degreees – the zone where bacteria multiply rapidly. Whether or not the stock cools to room temp in 4 hours depends on a variety of things… like if they strain their stock and put it in more shallow pans or pans that conduct cool air more quickly, stir, etc. While it may take a while to get to room temp, any temp below 140 will bring about bacteria growth. Bringing to boiling is essential to kill any bacteria growth started, but thinking that it is safe if it goes to room temp isn’t always the case, although it will work the majority of the times. Having made literally thousands and thousands of gallons of stock through the years, there have been times when not keeping an eye on those variables caused me to have to throw some out because of the obvious spoilage. You can also very effectlvely reduce stock in the oven if you are careful about watching it the first time you do it to see how quickly it evaporates on your temp setting.
I have been making stock since June when I learned and WILL NEVER go back to store bought. This past batch was the best yet– it was SO gelatinous! I put 2 jars in the fridge for easy use and sure enough, my son felt under the weather. I scooped (not poured, b/c it was so perfectly gelled!) the stock in my pot, added incredible English Peas we got from a local farm and shelled ourselves, sliced carrots, added a handful of egg noodles and cut up leftover chicken that had cooked in fresh garlic and lime sauce (YUM) and, my kids ate every single drop. The illness never came to fruition, kids were like normal afterward, I even took 2 thermoses to the ball park Saturday with the soup for my lunch. Thank you for all your instruction. It has transformed my kitchen.
