Hearty beef casserole

Method:

Heat 1 tablespoon oil in a large saucepan over high heat. Cook beef, in 4 batches, stirring, until browned. Transfer to a plate.

Reduce heat to medium. Add remaining oil, onions, leeks, garlic, celery and carrots to pan. Cook, stirring often, for 5 minutes.

Return beef to pan with tomatoes and stock. Bring to the boil. Reduce heat to low and simmer, covered, for 1 hour. Uncover and simmer gently, stirring occasionally, for 30 minutes or until beef is tender.

Divide the casserole between 4 plates.
