Helpful Tips

Choose chuck roast: Beef chuck has enough marbling to stay moist during slow cooking and becomes wonderfully tender over several hours.

Don’t discard the juices: The onion-infused cooking liquid adds a lot of flavor and helps keep the shredded beef juicy.

For sandwiches: Spoon the shredded beef onto toasted hoagie rolls and top with melted provolone for a French onion-inspired beef sandwich.

For extra flavor: Add a little beef broth if you prefer more liquid for serving over mashed potatoes or noodles.

Cheese choices: Provolone gives the dish a classic savory flavor, while mozzarella creates a mild, stretchy topping. Swiss cheese is another delicious option.

Storage: Refrigerate leftovers in an airtight container with some of the onion broth. Reheat gently to keep the beef moist.
