Step 1: While the finished cooked roast is resting, pour the pan drippings into a skillet. Set to medium-high heat. Add in butter, stir until melted.
Step 2: Add in broth, thyme leaves and Dijon mustard; bring to a boil, cook whisking often until the sauce is reduced by about half and slightly thickened, about 10 minutes.
Step 3: Whisk in 2 tablespoons heavy cream and pepper until mixed thoroughly, if you like the sauce more creamy add in more heavy cream.
