Is it safe to leave a slow cooker on for 12 hours? Yes, you can use your slow cooker for longer than eight hours, as long as you keep an eye on it. Many slow cookers do have an automatic shutoff after 24 hours.
Slow cookers are designed to be left on for extended periods of time, so it is safe to leave one on for 12 hours. However, it is important to note that slow cookers can vary in terms of how long they take to heat up and how hot they get, so you may want to check the food occasionally to make sure it is not overcooked.
When using the warm setting on a slow cooker, most manufacturers recommend a duration of only up to four hours to keep food warm without compromising quality.

As long as its on cooking or the warm setting its safe. If you turn it off and leave it on the counter, thats asking for food borne illness.
Safety First
The thought of leaving the house with an appliance running can be unsettling, but slow cookers work on low wattage (only as much power as 1-1/2 100 watt light bulbs) and are designed to perform while you're away.
You certainly can, the meat will simply fall to bits, which might be desirable for some recipes like “Chicken and Dumplings” which will take 8–12 hours on “Low” setting. As long as the temperature remains above 140 F you can leave your chicken in the cooker all day but try to avoid more than 12 hours…
However, if you are planning to leave your slow cooker on overnight, make sure it's on a low heat. You may wonder how long can you leave a slow cooker on low for? Well, the recommendation is a maximum of 8 hours on a low heat for most slow cookers.

Food should not be at room temperature for more than two hours. Shallow containers or small amounts of hot food can be placed directly in the refrigerator or rapidly chilled in an ice or cold water bath before refrigerating. Cover foods to retain moisture and prevent them from picking up odors from other foods.
I have cooked this chili for 9 hours on low and it was delicious but ever-so-slightly burnt on the top. The tomatoes contain sugar, which caramelizes and will eventually burn. Anything longer than 10 hours on low is risky.
The difference is the time it takes to reach that temperature. Low: 7-8 hours to reach the simmer point. High: 3-4 hours to reach the simmer point.
Reheating leftovers in a slow cooker is not recommended. Cooked food should be reheated on the stove, in a microwave, or in a conventional oven until it reaches 165 °F. Then the hot food can be placed in a preheated slow cooker to keep it hot for serving—at least 140 °F as measured with a food thermometer.
Given how close that temperature is to the Danger Zone, Crock Pot recommends that you only keep food on the warm setting in your slow cooker for up four hours.
Approximately 4% of all residential fires are caused by small appliances like crockpots.
Stick to the cook time indicated on your recipe
Most slow cooker meals take 8-12 hours on low or 4-6 hours on high, but there are also recipes for slow-cooked meat that take up to 24 hours. If you want to avoid overcooking your dish, follow the given guidelines as closely as possible.
Cover the crockpot and cook on LOW for 10 to 12 hours or until the beef and vegetables are tender. Skim the fat from the rendered juices. Add the juices to a pot, add the butter and mix well until combined. Remove from heat once it has reduced a little and has a good texture.
A longer cooking time isn't always better in the slow cooker. "There's usually no benefit to cooking a stew for more than six hours," Leung told BI. "After that point, the texture of most meats will start to turn dry and tough."
This makes slow cookers a great way to start out cooking joints if you have not used an oven before. If you want the beef to fall apart more you can simply cook it for longer, up to 12 hours, however it will not slice as easily after this.
Unlike other cooking appliances, you can leave food in a slow cooker unattended for hours at a time. This is what makes them so useful as a kitchen tool; you can pop your favorite meal in to cook in the morning, then return home after a busy day at work to freshly cooked, delicious food.
I cooked the beef stew on low overnight and had my husband shut it off when he got up so it would cool enough for me to put it in the refrigerator before I left for work. It was so good I couldn't stop taking bites.
Don't Overfill Your Crockpot
Most recommend filling a crockpot one-half to two-thirds of the way. Overfilling it may cause the contents to boil over, while not enough liquid may burn your dinner.
How Long Can Food Sit Out? The U.S. Department of Agriculture (USDA) food and safety basics states cooked food can be left at room temperature up to two hours. If the temperature outside (or inside your house) is 90°F or above, you should cut that time in half.
Research conducted by USDA FSIS indicates it's safe to cook large cuts of meat and poultry in a slow cooker.
We Recommend
It seems almost impossible that meat could get overcooked at such low temperatures, but while it is unlikely, it is still possible.
