Instructions. 1  Barely cover the bottom of your slow cooker with water. 2  Place the turkey in the crock-pot. 3  Season as desired. 4  Cover and cook on low for 8-12 hours depending on the size of the bird. 5  You could start this the night before and free up oven space, and you'll be ready for an early afternoon feast if desired.o now at Thanksgiving I slow cook a turkey AND bake a turkey, JUST in case they didnât turn out, plus I LOVE the leftovers. Now you might have to get a smaller bird. Actually, you can ask the butcher to cut your bird for free (maybe Iâll do that this year). I have a 7 quart crock-pot that I used for this one.
1 Cook the roast until it is 190 to 200F internal temperature. 2  During the dook, the liquids collected may be removed and chilled for defatting. 3  Depending on how hot your crock pot cooks, this may take 6 to 10 hours on low or 4 to 5 hours on high. 4  I recommend using temperature rather than time. Add enough rub to cover the roast evenly (don't be stingy). 2  Using hands, rub the spices and mustard into the roast on all sides. 3  Place 1 1/2 inch balls of aluminum foil in a 4 or 5 quart crock pot to raise the roast above liquids that will collect in the pot.
