To enhance the flavor of brown gravy, consider adding depth with ingredients like caramelized onions, minced garlic, or finely chopped mushrooms. You can also incorporate savory elements like Worcestershire sauce, soy sauce, or beef bouillon for richness. For a touch of freshness, sprinkle in some chopped herbs like thyme or rosemary. And don't forget to season with salt and pepper to taste! These additions will elevate the flavor of your brown gravy to new heights.
I usually add a splash of Worcestershire sauce and a pinch of thyme to my brown gravy, it gives a nice depth of flavor. Also, try deglazing the pan with a bit of red wine before adding the broth, it really enhances the richness.
