Extra Debri Gravy Instructions

This recipes creates a delicious gravy as it cooks and usually is plenty for the amount of meat. However, if you would like extra gravy you have couple options.
1. When beginning to cook add an additional brown gravy packet and 4 cups of beef broth or water for extra gravy.
2. If you have already cooked as instructed and decide you want more gravy, remove beef to a plate or cutting board to shred. Add in 2 cups of beef broth and then make a cornstarch slurry with ¼ cup water and 3 tablespoons cornstarch. Stir into liquid in slow cooker, let thicken and enjoy.
3. If you want to go all out for a creamy gravy, you can skim off about ½ cup of drippings. In a skillet over medium high heat, add 3 tablespoons butter and ⅓ cup flour, stirring with a whisk cook flour for 1 to 2 minutes. Add in drippings and slowly pour in 1 to 2 cups of heavy cream or to desired thickness. If you want a more traditional debris gravy skip the cream and use beef broth instead.
