I’m going to go against popular opinion here. u003cemu003eu003cstrongu003eNo, I don’t think this recipe can cook for 8 hours or longer. u003c/strongu003eu003c/emu003eu003cbr/u003eu003cbr/u003eOver the last ten years, I’ve made steel cut oats in the crockpot many times, and the few times I tried to cook it overnight, it resulted in mush that stuck to the sides.u003cbr/u003eu003cbr/u003eIn my experience, the perfect cooking temperature and time is 4 hours on low and then 2 hours on warm. u003cbr/u003eu003cbr/u003eI don’t recommend cooking it over 4 - 5 hours on low because it will burn and turn into mush. u003cemu003eAlso, I never recommend cooking slow cooker steel-cut oatmeal on the high setting.u003c/emu003eu003cbr/u003eu003cbr/u003eOf course, that’s been my experience using my slow cooker.
