Tips
Check doneness by testing with a fork - the meat should flake apart easily when properly cooked.
Keep the pan tightly covered throughout cooking to prevent moisture loss and ensure even cooking.
Let the roast rest for 10-15 minutes before slicing to allow juices to redistribute.
Good to Know

Can be prepared 1 day ahead and reheated gently in oven.
Slice against the grain and serve with the roasted vegetables and cooking juices.
Common Mistakes
Don't rush the cooking time to avoid tough, chewy meat.

Don't slice too thick or the meat will be difficult to chew.
