@whiskeyarmadillo and @Titsywoo Broadly, I agree and said this up front but one thing I will say is that I think timings for a lot of slow cookers are wrong. In mine, on low, a lamb/beef based dish really needs at least 9 hours, or even 10 rather than the 8 that is so often recommended. Or 5 on low vs the popular 4 and I sometimes think that's part of the reason they're better in a proper pot on the stove or in the oven. I now routinely go for 9-10 high or 5 slow for any red meat based stew or casserole.
I saw in the Nagi recipe book the other day that she does a lamb shoulder in the oven which she cooks for 12 hours at 100C. A slow cooker on low is unlikely to be much higher than that so I think that really brings home the point that at the very very low temp of a slow cooker, you really do need the extra time.
Having said that, I have made spaghetti bolognaise in regular my regular large saucepan, regular large pot, my le creusset pot and my slow cooker and without a doubt, the le creusset tastes better every time so.... [shrug]
Another factor for a lot of slow cooker use is, I think, the meat used. A lot of people will buy "stewing" lamb/beef at the supermarket but it's often the most tasteless, overly lean meat. You really do need the right meat for a slowcooker. A beef shin, oxtail, or a lamb knuckle or neck or shoulder etc. The fat and the sinews or whatever they are is hugely important. Nothing makes me convinced that a TikTok recipe will be a disaster more than seeing cubes of red meat with zero fat or marbling or whatever going into the slow cooker before the other ingredients.
