How to make Pan Gravy

  • Strain the pan juices, and skim any extra fat away. Heat on a saucepan on medium-high heat. Make a slurry of ½ teaspoon of cornstarch and 1 teaspoon of water. Whisk in the slurry and cook for a few minutes until it thickens. Add extra broth to thin the gravy or extra cornstarch slurry to thicken if necessary. Serve with your roast lamb.
