French Dip Sandwiches
Our hands-down favorite use for leftover roast beef is French Dip sandwiches. But the beefy jus takes so long to prepare. We wanted to make these sandwiches quickly.
Why This Recipe Works
This French Dip Sandwiches recipe is our favorite way to use up leftover roast beef. For a quicker version of long-simmering jus, we enriched a blend of canned beef broth and chicken broth with browned scraps of beef, then thickened the broth with a little flour. The beefy jus is the perfect finishing touch for French Dip Sandwiches.
