What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the chuck roast extremely dry before searing for a deep, even crust.
- 2Let the seasoned roast rest at room temperature for a full 30 minutes to ensure even cooking.
- 3Don't skip scraping the browned bits (fond) from the pot after searing — that's pure flavor for the gravy.
- 4Turn the roast only once during the braise to keep the meat intact and tender.
- 5Shred the beef while it's still warm; it will absorb the gravy better and stay moist.
- 6For the most authentic po'boy, use a crusty New Orleans-style French loaf with a soft interior.
- 7Assemble the sandwich just before serving to keep the bread from getting soggy.
