Cornstarch gravy is an easy and versatile sauce, perfect for adding rich flavor to your favorite dishes. Whether you're making it for mashed potatoes, roasted meats, or even vegetables, this simple recipe uses cornstarch as a thickener to create a smooth, glossy gravy without flour. It's quick to make and delivers a silky, flavorful sauce every time. The best part? You can customize it by using chicken, beef, or vegetable broth, depending on what you’re serving it with.
Heat the broth. In a medium saucepan, bring 2 cups of your chosen broth to a simmer over medium heat.
Mix cornstarch and water. While the broth is heating, in a small bowl, whisk together the cornstarch and ¼ cup cold water until smooth.
Add cornstarch mixture to broth. Once the broth is simmering, slowly whisk in the cornstarch mixture. Stir continuously to avoid lumps.
Simmer until thickened. Keep whisking for 3-5 minutes as the gravy thickens. You’ll know it’s ready when it coats the back of a spoon.
Season. Add salt and pepper to taste. For a richer flavor, stir in the optional tablespoon of butter.
Serve. Pour the gravy over your favorite dishes, and enjoy!
If the gravy is too thick, simply add a bit more broth until you reach your desired consistency. If it’s too thin, mix a little more cornstarch with cold water and add it slowly. For extra depth, add a splash of soy sauce or Worcestershire sauce. A dash of garlic or onion powder can also elevate the taste. If you want a perfectly smooth gravy, pour it through a fine mesh strainer before serving.
