  • 4 cups beef broth

  • 1 teaspoon salt
  • 3 tablespoon tomato paste
  • 3-4 sprigs fresh thyme
  • 2 large bay leaves

Instructions

  • Salt and pepper the roast. Heat olive oil in a large skillet, sear roast on all sides. Place into the slow cooker.
  • If no oil is left in frying pan add 2 additional tablespoons of olive oil or butter. Whisk in the flour and cook until browned. Deglaze with the red wine, whisking under there are no lumps of flour. Stir in the tomato paste, beer, Worcestershire sauce and beef broth.

Shake well to make sure there are no lumps. Heat the broth on the stove top to boiling. While constantly whisking, gradually add the flour slurry mixture a bit at a time until you achieve the desired consistency. Reduce heat and cook for a few more minutes to thicken.
