Now that the meat is seared well, you can add 2 cups of water and 32 ounces of chicken or beef stock, to the bottom of the pan. Place the cover on the pot and place in the pre heated 350 degree oven. This roast will take about three and a half to four hours to slow cook. About halfway through turn the roast over in the pot, and add more water or stock to cover meat at least halfway.
