These toasty Slow Cooker French Dip Sandwiches are made with slow cooked roast beef and served on crusty rolls with melty cheese and savory au jus.
Using a frozen roast is fine; just add it to the slow cooker without thawing. You can also skip searing the meat and cook it directly in the slow cooker.
