Lifting lid on slow cooker

Slow cookers | 0 comments

Lift or do not lift the lid on a slow cooker, that’s the big question of our time.

On the one hand, you don’t want to slow down the cooking or let the moisture and taste escape out of the slow cooker, but at the same time, you want to check the magic and maybe add some last-second ingredients.

So what should you do?

Is it a good idea to lift the lid from slow cooker if it is not done cooking the meal? Is it dangerous? Will it ruin the process? And what is actually happening inside the pot of your slow cooker?

Let me answer these and other questions that you might have below.

Lifting the lid before the meal is done

In general yes you can do it. 

BUT and this is a big one. 

Do it at the end of the cooking time. My recommendation would be about an hour before the end of cooking time. 

Reason for this is the fact that in the end the biggest part of cooking is done and the thing that is happening in the last hour is melting and deepening of tastes.

This way you are not going to ruin hours of waiting and overpowering your hunger and lust for that succulent meal. 

So what happens when you lift the lid early?

To answer this question, let me paint you a picture or two.


Once you remove the lid, much heat – about 10 to 20 degrees is released/lost immediately.

Yes, I meant it literally. 

So let’s go about it in detail. Not as much detail as I wrote here about how does slow cooker work, but specific enough to understand.

The whole magic of a slow cooker is in the gradual build-up and subsequent keeping of a heat. 

So whenever you lift the lid too early, you release a tremendous amount of heat. As temp drops and moisture leaves the pot, whole cooking gets a massive hit for which you have to compensate by extending the cooking time.

Since it hugely depends on a slow cooker, recipe, time, and temperature, it is hard to say precisely by how long to extend cooking. Still, in general, my recommendation and the best experience is to prolong cooking by 15 minutes for every minute you have a slow cooker open. 

Add extra 15 minutes if you not only lift the lid but also stir the insides. The reason is similar. As you stir, you are letting more heat escape the cooking pot.

Is lifting the lid before the end dangerous?

Hell yeah, it is. 

You have to realize that as you lift the lid, you release a massive amount of scorching vapor and moisture.

So whatever you do, NEVER, EVER, keep your face or any other body parts above slow cooker as you open it.

Best case scenario, nothing terrible happens. You might get a bit scared by heat and at the most, drop and break the lid.

Worst case? You got 2nd, and 3rd degree burns on your arms and face, not so good for just wanting to see something.

Also, if you are living with someone else in your household and you are afraid for their health and safety, tell them that you are cooking, and they should not open the lid. 

If they are younger, slap the sticky note on top of the lid, saying things like Danger! Do not touch!

And if you have a baby around, do him a solid. Still, the slow cooker in a safe space and as an additional safeguard put a tape on it in a way that it connects base and lid of the cooking pot, so your little angel can not open it.


So lifting the lid is ok, as long as you stick to necessary safety precautions as we discussed above and remember to extend the cooking time by an appropriate amount of time.

I hope this little article helped you and I will see you next time. 

Until then, I wish you a happy and relaxed cooking.
