It’s important to keep the steak submerged in liquid while it’s cooking in the slow cooker. Make sure that you add the right amount of broth into the mix so that it cooks well. Also, avoid lifting up the lid during the cooking process. This will affect the internal temperature of the slow cooker, and the heat can drop significantly. Lastly, stick to the cooking time! Don’t overcook the meat or else the liquid sauce will dry out.
