Recipe for 12 filled a large crockpot. 10 hours is too long. I cooked it for 8 hours, but will probably turn it off around 7 hours next time. . Added milk and kept on warm all morning. It was very good.
I used regular oats (not quick cooking) and this turned out extremely soupy and gross. Oats were burned/caked around the edges of the pot. Completely inedible. Steel cut oats may work better.
I only cooked for about 7 hours, Fabulous!!
