Great for camping or casual meals at home, this nontraditional French dip is a fun pull-apart sandwich that comes together quickly, thanks to a couple of shortcuts: roast beef from the deli and a quick “au jus” made from butter. We might not have a homemade roast or a pan full of drippings, but we definitely aren’t short on flavor here. Keep in mind the au jus will only be as good as your beef broth, so it’s worth using a well-seasoned homemade broth or seeking out quality bone broth from a butcher shop.
If you plan to put leftover rib roast in these sandwiches, use the luscious pan drippings from your roast in place of the butter to make the au jus that much better!
