Are Slow Cooker Liners Worth It? We Use Them Every Time Now
I wish we had discovered slow cooker liners earlier.
That is about as complicated as my review needs to be. They fit the same practical-kitchen category as the food processor I have kept using for years and the odd little can opener that won me over.
We use crock pots regularly, and now when one comes out, a liner goes in it. The day I was talking through this article, we actually had two crock pots going for a family dinner. Both had liners.
My short version: yes, slow cooker liners are worth it for us because they save cleanup time. We have had a couple of small leaks, but I think we caused those by poking the liner with a fork or knife while pulling apart very tender meat.
This became a repeat purchase for a reason
My Amazon history shows Reynolds slow cooker liner purchases going back to 2020, followed by repeated orders in 2024, 2025 and 2026.
That is not proof that everybody needs them. It is pretty good evidence that our household did not try one box and forget they existed.
Once we started using them, they became part of the slow-cooker routine.
The main benefit is exactly what it looks like: cleanup
Slow cookers are great at turning food into something tender over several hours.
They are also good at leaving cooked-on residue around the inside of a heavy ceramic crock.
A liner catches most of that mess. When dinner is over, cleanup usually involves removing the liner instead of soaking and scrubbing the entire crock.
Reynolds currently markets its liners around the same no-scrub convenience. That is the benefit I actually experience.
We use them every time now
I am not someone who thinks every disposable kitchen product is worth paying for. I buy cheap coffee filters because they disappear into the trash after doing a very simple job.
Slow cooker liners are different for me because the disposable part removes a chore I notice.
That is the value calculation: the liner costs something, but I get cleanup time back.
Yes, we have had a couple of leaks
I do not want to pretend they are indestructible.
We have had a couple of small leaks. In both cases, I think we probably nicked or poked the liner while using a knife or fork to pull apart meat that had become very soft.
That taught me something fairly obvious: if the point of the liner is to remain a bag, stabbing it is not especially helpful.
I would use appropriate utensils carefully and follow the product directions rather than expecting thin liner material to shrug off sharp metal.
What Reynolds currently says about the material
Reynolds currently says its slow cooker liners are made from a BPA-free nylon blend intended for slow-cooker use on high, low and warm settings, and says the material is FDA-compliant for cooking.
The company also says the liners are designed for slow cookers, not as a universal plastic liner for ovens, stovetops, grills, air fryers or other appliances.
I include that because ‘Are slow cooker liners safe?’ is an understandable question, but my personal experience cannot answer a materials-science question. The manufacturer’s current use instructions are the right place for that.
Which Reynolds liners have we bought?
#ad
My order history includes the older Reynolds regular-size liner packs and repeated purchases of the current regular-size 3- to 8-quart liners.
The exact package size has changed depending on what we ordered. The important part for me is choosing a liner designed for the crock-pot size we are actually using.
Who probably does not need these?
If you rarely use a slow cooker, do not mind scrubbing the crock, or simply do not want another disposable kitchen item, skipping liners is perfectly reasonable.
This is convenience, not necessity.
But if a dirty crock sitting in the sink is one of the reasons you hesitate to use the slow cooker, I understand exactly what this product is solving.
Would I keep buying slow cooker liners?
Yes. We already do.
There are products where repeat purchases are annoying because the original keeps failing. This is the opposite. We repeat-buy slow cooker liners because using them means less work after dinner.
