READY IN: 7hrs 15mins
Recipe by Debbie R.

From Mable Hoffman's Crockery Cookery. I really liked this crockpot dish. Flank steak is lower in fat than many cuts.

Yummers! We really enjoyed this meal! We had this with scalloped potatoes and veggies. The only change I made was to use Dijon because we prefer it. For me, I cut it against the grain and it was very tender and not stringy. Also next time I think I would put the sauce in a saucepan to thicken it because it didn't really thicken much. Made for my fellow Kitchen Witch for ZWT5. Thanks!

Ingredients Nutrition


  1. Put steak in crockpot.
  2. Combine wine, soy sauce, garlic, broth, ketchup or tomato paste, mustard and onion. Pour over steak.
  3. Cover and cook on low for 6 to 7 hours.
  4. Turn to high. Dissolve cornstarch in water; stir into crockpot. Add mushrooms.
  5. Cover and cook on high for 20-30 minutes or until mushrooms are tender.
  6. For serving, meat should be cut across the grain.
  7. Note: I remove the meat to a plate and cover with foil. I then put the sauce in a saucepan and heat over med-hi to high heat while stirring so that it's done more quickly than the method stated above.
