Make Ahead Tip: The pot roast will keep, covered, in the refrigerator for up to 2 days. Reheat meat slices and sauce, covered, in the oven, microwave or on the stovetop.
Ingredient Note: Although it is not the leanest cut of beef, chuck is still our choice for pot roast because it doesn't dry out during braising. You will find pockets of fat as you carve it, but they are easy to remove.
For easy cleanup, try a slow-cooker liner. These heat-resistant, disposable liners fit neatly inside the insert and help prevent food from sticking to the bottom and sides of your slow cooker.
