This is not the best way to cook it. Crock pots r used to slow cook food. Put it in with water (2/3s full). Cook about 5 hours. If u want it cooked sooner, bake it till its 170 degrees @350 (about 50 -70min). also i'd wrap it in tin foil or cover it. bake it with your soup
You should cook the 2 lb boneless turkey breast in a crock pot for roughly 5-6 hours. There is no need to put water on the bottom, but you can apply chicken broth instead. In addition, you should cook on low heat and you should mix other ingredients like butter and thyme.
