I've never used the slow cooker to make spaghetti sauce! Started on the stove and transferred to slow cooker. Checked temp when I returned home hours later and it was at 204! Nooooo! Colleen
I agree with Marilyn, just skim it off. If it is not very much, just stir it in and use. . .
My stove-top red sauce for spaghetti tends NOT to break, but I do stir it frequently. If I don't stir it for a while, it will break. As I don't stir my sauce in when cooking it in the crockpot, it almost always breaks; I either skim or stir back in as the fat atop is usually not very much, nor very thick.
