First, pour the beef broth through a strainer to remove any solids. Pour the broth into a skillet, allowing it to heat gently.
Next, take about 3 tablespoons of the broth and transfer it to a small bowl. This will be used to create the cornstarch mixture, which is key to thickening the gravy. Add the cornstarch to the bowl and whisk it together until well blended. You want to ensure there are no lumps.
Now, bring the broth in the skillet to a simmer. You’ll see gentle bubbles forming on the surface. This is the perfect time to whisk in your cornstarch mixture. Keep stirring as you add it in, making sure it blends smoothly with the broth.
As the mixture cooks, you’ll notice it beginning to thicken. This will usually take a few minutes. Keep an eye on the color; it should deepen slightly as it thickens.
Once the gravy is thickened to your liking, it’s time to taste it. Add salt and pepper according to your preference. A little seasoning goes a long way in enhancing the flavors; feel free to adjust to make it just right for you.
Finally, once satisfied with the flavor and thickness, remove the skillet from the heat. Your Pot Roast Gravy is now ready to serve and enjoy!
