  • ¼ cup flour
  • 3 tablespoons olive oil
  • 2 tablespoons butter
  • 3 cups mushrooms sliced
  • 1 medium onion chopped
  • 2 cloves garlic finely chopped
  • ½ cup red wine
  • 1 cup beef broth
  • salt and pepper
  • ½ teaspoon paprika
  • 1 tablespoon Dijon mustard
  • 1 tablespoon whole-grain mustard
  • ¾ cup sour cream
  • Fresh parsley, chives or green onions chopped
  • 2 tablespoons cornstarch optional


  • Cut beef into slices, season with salt and pepper.
  • Dust the slices of beef with flour.
  • Heat olive oil in skillet, and sear meat on both sides.
  • Transfer to the slow cooker.
  • In the same skillet add the butter. Sauté onions, garlic and mushrooms until tender. Transfer to the slow cooker.
  • Deglaze the skillet with red wine.
  • Stir in the beef broth, paprika and both mustards.
  • Pour over the beef and stir together.
  • Cook on low setting for 4-5 hours or high setting for approximately 2 hours.
  • Before serving, stir in the sour cream.
  • Garnish with fresh parley, chives or green onions.

If you find the broth is not thick enough, ladle out ½ cup of broth. Whisk the broth together with 2 tablespoons of cornstarch. Stir into the beef and cook on high for an additional 20 minutes or until sauce thickens.
