When slow cooking goes wrong, there is an identifiable taste to it.. I don’t know how or why it goes wrong.

AIBU to wonder if you can overcome that weird taste it develops?

There really is a distinctive 'slow cooker' taste. My son dislikes it even more than I do and I even tried a second slow cooker - ceramic rather than aluminium. Browned off any meat, pre cooked the onions - still odd.
I've gone back to the oven on a low heat and my le Creuset casserole dishes.

It’s definitely not this.

I brown everything before it goes in the slow cooker (several other posters have said they do the same).

Reading this I suspect the difference in people’s ability to taste is quite significant

Agreed, it’s just slow cooker taste

thats why you’ve never tasted it. It’s the onions. If you just bung everything in the slow cooker and turn it on everything has a slightly raw onion taste (if using onions). If you brown everything or at least the onions on the hob first it tastes fine.
its why I gave up using mine. The only point to them was to be able to bung everything in at the start of the day. If you have to brown everything first you might as well just cook it on the hob.

Same herw.

I have no idea what a "slow cooker taste" is.

Mind you, I always brown everything before it goes in the slow cooker, and the results taste the same as something that has been oven cooked.

Oh, I've mentioned this for years to DH and my mum and neither of them have known what I've been on about! I think it's where the liquid shrinks away from the edge of the pot a bit and browns/burns ever so slightly. Then it all gets stirred in. You know like when you're cooking on the hob and get distracted and then the sauce catches a bit on the bottom, so you scrape and stir it like mad to mix the few black bits in? There's always the very slightest taste.

ShowOfHands · 22/02/2026 22:58

DD and DS refuse to eat slow cooker food as it tastes of slow cooker apparently. A friend is the same. Nothing to do with browning or reducing liquid. Maybe it's like coriander and some people can't taste it and some people can.

Magnalux · 22/02/2026 22:55

Yea I get this too kind of like a slightly celery taste ( I hate celery) really puts me off. ive put the slow cooker away and resurrected many times over the years. However I think I’ve cracked it, the slow cooker is on.too long.. from when I leave until I get home could be over 9 hrs. I bought a WiFi plug so can turn it on from work about 10-11 am rather than when I leave at 8. So far it’s working and I haven’t noticed the taste the last few things I’ve made!

StripedVase · 22/02/2026 22:49

I honestly think this is a thing some people pick up on and others don't! I got given one, cooked a bunch of different things, followed recipes exactly, ended up getting rid of the thing because everything had a weird undertaste to me.

GenuineWorkOfFart · 21/02/2026 19:29

It's not just meaty things, because we are veggie and I still get the weird flavour!

This thread has made me feel better. I always thought it was just me with this problem.

DrinkFeckArseBrick · 22/02/2026 10:21

I agree there is a slow cooker taste. I think it's because when you cook in an oven (or even on the stove), the exposed parts (eg meat that's sticking out) caramelises, and the sauce reduces and concentrates flavour. So for example you can bung in half a bottle of wine and it evaporates leaving a lovely sauce, whereas if you used the same in the slow cooker it would just taste too 'winey'. So yes there is a definite slow cooker taste and doesn't mean your slow cooker is broken.

As to how you overcome this, I think it's difficult ans involves some extra steps that negate the point of a slow cooker. I'd suggest browning meat and sautéing veg before adding. Season really well and add a bit of sugar to replace the natural caramelisation. And afterwards consider draining, reducing the sauce in a saucepan at a rolling boil, and then adding back in. It's unlikely to taste the same as roasted though.

People generally add less seasoning than they nedd in my experience. That's why slow cooker food tastes weird sometimes

But that doesn't explain why you can cook a meal for say, four people, and not all those people can taste the weirdness.

I genuinely think it's just that some people have a stronger sense of taste than others.

I think it’s just a case of some people being able to taste it and some people not.

Like a PP I’m autistic and a bit of a super taster around food, so I suspect that comes into it for me.

I suspect you're right. I might have occasionally had a hint of it when using canned tomatoes, but I usually use fresh, then I don't notice it.

This is useful to know because I was worried about getting an air fryer incase it had the same issue! I also can’t believe I’ve found so many other people on here who have found this too.

Use my airfryer most days and never had any issues with it, everything tastes great.

I used high quality ingredients in a new cooker.

Still tasted horrible.

Yep me too - my slow cooker is ceramic and I always use decent butchers meat and mutti tomatoes.

This thread has totally validated me - my slow cooker is going in the bin

Yes this is why we gave up using a slow cooker. And I'm not fussy. But everything has that taste to it. Have now gone in the opposite direction and air fry almost everything, and it's nicer and easier.

fashionqueen0123 · 22/02/2026 09:20

I gave mine away due to this! I made a few different things and they all had this weird taste. Glad it’s not just me!

saltandvinegarpringles · 22/02/2026 09:18

dragonfruit8 · 21/02/2026 23:54

Some research suggests that the issue is either caused by low quality ingredients, acidic ingredients, or a damaged inner. Also suggested more expensive models are less likely to have the issue. I can't verify any of this. My models are mid-range prices and I do use high quality ingredients. It's not a problem I've ever had.

My food doesn’t have a specific slow cooker taste but never tastes as nice as when it is slow cooked on the hob or in the oven. I brown meat and fry off onions/soffrito mix etc but it’s never as rich when you do it in a SC.

Tend to only use mine for pulled pork and keeping things warm on a buffet now.

They do sound revolting though. I try and cook from scratch.

Yeah, those recipes are grim. It always makes me laugh when the whole thing consists of throwing in multiple cans of soup, loads of msg-laden seasoning, and a bag of grated cheese. That’s not cooking 🤢.

Not sure if it’s been mentioned already, but the Taming Twins website has some really good slow cooker recipes. I’ve never had one of those go wrong.

PersephoneParlormaid · 22/02/2026 06:31

food cooked in my slow cooker definitely tastes different from food cooked in a casserole dish in the oven, I prefer oven cooked.

I'm so glad to read so many people get this weird taste from a slow cooker! I thought I was just rubbish using it. When I have to brown and fry in a different pot anyway to make it edible, I see no need for a slow cooker. Much happier with a cast iron casserole dish.
