In a Dutch oven over medium-high heat, brown roast on all sides in oil; drain. In a large skillet, saute onions in 2 tablespoons of butter until tender. Add the water, soy sauce, soup mix, garlic and, if desired, browning sauce. Pour over roast.
Cover and bake at 325° for 2-1/2 hours or until meat is tender.
Let meat stand for 10 minutes, then thinly slice. Return meat to pan juices. Split bread lengthwise; cut into 3-in. sections. Spread with remaining butter. Place on a baking sheet.
Broil bread 4-6 in. from the heat for 2-3 minutes or until golden brown. Top with beef and onions; sprinkle with cheese. Broil for 1-2 minutes or until cheese is melted. Serve with pan juices.
Notes
Onion Beef au Jus
Garlic, onions, soy sauce and onion soup mix flavor the tender beef in these savory hot sandwiches served with a tasty, rich broth for dipping. The seasoned beef makes delicious cold sandwiches, too. —
