For a leaner version, choose eye of round beef and remove visible fat before cooking.
The pot roast can be made in a slow cooker on LOW for 8-10 hours or HIGH for 5-6 hours.
Leftovers keep well for up to 4 days refrigerated or up to 3 months frozen.
For thicker gravy, mix 1 tablespoon cornstarch with 2 tablespoons cold water and stir into the simmering liquid.
