  1. Wonderful recipe! I use it to make ahead meals and use the beef all the ways you suggest. My recipe is different in that I put in a can of cream of mushroom soup to make the gravy! Thanks for posting this! DonnaTMann Northern Calif.
  2. Like many, I follow the basic methods and adjust ingredients to satisfy our needs and tastes. In this case, the veggies and *thoroughly* browning the meat are a a huge plus! I ship the onion soup and 'Au jus' mixes, substituting more garlic, more fresh onion, variable herbs of choice and my own beef stock and/or Beef Extract to achieve the necessary fluid volume. The robust flavors do make it into the meat, an inexpensive, lean, usually tough cut that it made mouth-melting tender and tasty. The (cooked) meat can be used for any number of other dishes or stand on its own. Wee reduce the salt content for taste reasons (not health). Those with health-salt issues can cut the sodium content by half with these simple changes. The sodium level is the only reason I've not given this method five stars. For our favorite Beef Stew, I cube the meat before browning and change the seasoning a little, use slightly smaller veggie chunks (adding them later), use more veggies and cook for only 5-6 hours. The wife likes it so it has become the go-to. Simple is usually better than complicated...
