I've just started using a slow cooker, and have had pretty mediocre results in keeping my meat moist vs. conventional cooking. For example, the chicken always seems overdone and dry. Even my beef stew has been on the dry side, with my latest one almost inedible (not tough--just dry) after 7.5 hours on Low. My question is: Am I simply overcooking it (i.e. the slow cooker might be hotter than the recipes call for)? Should I start adjusting my times down, and if so, by how much? Or is it meant to be stewed longer? Should I add more liquid? The vegetables seem perfect, though.
I've actually used several different models of slow cooker (some borrowed, some bought and returned), and they all seem to dry the meat.

This may come as a surprise, but what is likely happening is that you are overcooking the meat. We tend to think that if you stew meat, the longer it cooks, the more tender and juicy it gets. In fact, this works only up to a point.
As proteins heat up, they loosen their internal bonds, begin to uncoil and bond with neighboring protein molecules. See Custards and Sauces for a description of how proteins change with temperature.
However, at somewhere around 170°F (76°C), depending on the meat used and the other ingredients present, the protein network begins to break apart again and and the individual molecules tighten back up. As that happens, the muscle fibers in the meat shrink, their cell walls break open and the water that was trapped within the muscle fiber starts to leak out. The result is that the texture of the meat becomes dry even though it was cooked in liquid. The same thing can happen in a pot roast or even with meat dishes cooked on the stovetop.
If you're like many people who start supper in the slow cooker before you leave for work in the morning then you are taking part in a balancing act. You are trying to cook the food at a sufficiently high temperature so that it gets out of the danger zone for bacterial growth fairly quickly. That temperature range is between 40 °F and 140 °F (4 °C to 60 °C). On the other hand, you don't want to overcook the meat to the point of being too dry. This isn't an easy balance to achieve.
I would try cutting the meat into somewhat larger chunks, perhaps up to about 2 inches (5 cm) to a side, and cooking for a shorter period of time. Once the cooker gets up to temperture, try cooking the food for about 5 hours longer. That should give you a total cooking time of about 6 hours. If the meat is still coming out dry, reduce the time by another half hour or so. For safety, though, always be sure that the meat is cooked completely.

Thanks so much for answering my question! I'll start reducing my cooking time, and maybe ask the butcher to cut the stew into larger chunks. I think the slow cooker is fabulous, but it's been a real letdown on getting meat to be good because of this overcooking issue. I do feel that the cookers seem to be hotter than the recipe books expect; maybe a change in the slow cooker industry to ensure no bacterial contamination?

Yay!!! I've been googling for a half-hour trying to find an answer to that question. I bought a crock pot recently - found tons of recipes on-line and always ended up with dry meat. Definitely going to start backing off the times in 1/2 hour increments. Thanks!

I know it's 3 years since the last comment, but still valid info! My roasts are always dry too even with great cuts of meat and I'm sure it's because my pot is too hot and needs less time rather than longer. It also boils which I'm pretty sure is not supposed to happen. The one Costco sells might not be a good choice. Thanks!

I have the one that Costco sells. I also have wondered if it is too hot! My meat always turns out dry!

Glad I found this I was going to give up cooking meat in the slow cooker. I follow the recipe to the "t" and always end up with really tough meat. This is a lot of wasted money. I really wish a crock pot was made that actually listed the temperature on it rather than "high" or "low" as that is really vague. I am getting ready to dump out about 6 pounds of beef ribs tonight because they are way overcooked. Yuck.
