How to test your slow cooker temperature.

If you’ve noticed that your slow cooker recipes aren’t turning out quite right or if it has been around longer than your grandmother’s recipes it might be time to test it.  A slow cooker needs to run at an optimal temperature to ensure food safety and proper cooking.

While a poorly functioning slow cooker can cause your meal to spoil or not to cook properly, it can also be a real danger in regard to food safety.

slow cooker should have a low enough temperature that you don’t need to tend to it however the temperature also needs to be high enough to keep food at a safe temperature. This delicate balance is what makes a crock pot everyone’s favorite appliance for everything from dips to roasts.

Knowing that your slow cooker works is super-important. If your crock pot has been around a long time, it may cook too slowly, allowing bacteria to form in or on your meal. Your slow cooker should heat the food to at least 140 degrees within a four time frame. You’ll want to test yours to ensure it meets the current safety standards to keep your food safe (and ensure your meals cooke properly).

How to Test Your Slow Cooker

  1. Fill your slow cooker with water halfway to the top.
  2. Turn it on to the lowest setting and cover for 8 hours.
  3. Remove the lid and immediately take the water temperature.

The water temperature should be 185 degrees F.

If the water temperature is higher, it’s not a huge deal. You may have to reduce the cooking time for some of your dishes. You can also buy one of the small attachments that will automatically shut your machine off once your food hits the ideal temp. But, either way, there’s no need to toss your crock pot.

If the temperature is less than 185, however, you should sincerely think about getting rid of your appliance. A slow cooker on low should be about 200 degrees; while the high setting should be 300 degrees.

Between 40-140 degrees F is the “danger zone” in your slow cooker. Bacteria will grow quickly and easily in your food if it stays in that range too long. Your food will obviously spend time at that temperature no matter what but if your cooker is heating the meal too slowly, you are creating a breeding ground for yucky stuff.

So, keep your family safe and healthy by checking your slow cooker and paying attention. It could save you from illness, or just a lousy dinner.

My favorite slow cookers:

  1.  Hamilton Beach Set ‘n Forget Programmable Slow Cooker With Temperature Probe, 6-Quart.  I used this slow cooker for about 10 years for countless family meals. While I loved the slow cooker itself, I didn’t often use the probe.
  2. This Black & Decker slow cooker is great for a large family (7QT) while having an amazing price point and great reviews.
  3. If you’re looking for a smaller 4QT slow cooker, the Hamilton Beach Stay or Go 4QT Slow Cooker has great reviews and is fairly inexpensive and Crock Pot has a great 4-Quart Smart-Pot Digital Slow Cooker.
  4. And of course if you’re in the market for a multi-use appliance, you might like to consider an Instant Pot which is a slow cooker, pressure cooker, yogurt maker, steamer and more all in one.

  1. What is this information based on? According to Crock-Pot there isn’t a temperature for the low and high settings, but rather refers to the amount of time it takes to reach the simmering point – around 209*. Low will take 7-8 hrs, while high should get there in 3-4 hrs. Of course, thinking about this logically, getting to that temperature faster would mean the heating element is operating at a higher temperature. Given the explanation from Crock-Pot, it would seem that the max temperature of their product is 209*, but they never say that…..they only refer to reaching a simmer point

    Using an instant read thermometer will ensure that your unit is up to temperature. Crock-Pot® SlowCcookers reach the simmer point and stabilize on both “High” and “Low” at about 209°F.

    Understand the Low and High Temperature Settings
    Don’t think of your slow cooker like a stove top. Cranking up the dial might move the temperature up, but it’s better to think of your meals in terms of time. That’s why you should think of the simmer point first.

    The simmer point is the time it takes to bring all the contents of your slow cooker just below the boiling point. It’s right around 209 degrees. On the low setting, the time it takes to reach the simmer point is around seven to eight hours. For the high setting, it takes around three to four hours.

      While the information you’re seeing from Crock Pot may in fact be correct, please keep in mind that Crock Pot is a brand so the information may be brand specific while the information I have provided is generalized slow cooker information.

      The information provided on my site does state the that temperature should be a minimum of 185 by 8 hours (it could be higher, that is the minimum)… since crock pot states that the temperature should be 209F after 8 hours, this still aligns with the information provided.

      Hope that helps.

  2. Do you have a guideline for the high setting? I just put chicken in my 3 month old programmable slow cooker on high for 4 hours and it is almost raw yet! It was frozen, but I’ve never had this problem before.

    • I see that you say 300 degrees, but how fast should it get there?

      • On the high setting, the heating element can get to 300 degrees but the water temperature will never get over 212 F. Thermometers are calibrated in ice water or boiling water because the water maintains the 212 degrees at sea level.

        Also, don’t put frozen chicken in a slow cooker, because it will stay at unsafe temps for too many hours.

  3. This is SO useful and informative and I have never thought to test mine. I know mine runs on the hot side just based on recipe guidelines, if it says cook for 3-4 hours, mine is always done at the 3 hour mark, never the back end of the range. Thank you for this one!
