For a twist on the classic comfort food, try making shepherd's pie with chuck roast. Brown your chuck roast in a Dutch oven, then remove it and sauté some onions, carrots, and peas. Add in some beef broth and tomato paste, and return the roast to the pot. Simmer for a few hours until the meat is tender and the sauce is thick and flavorful. Top with mashed potatoes and bake in the oven until golden brown.
