Perfect Brown Gravy – Every Time! As an ode to my hubby, I thought I’d pass along my recipe for the perfect brown gravy! He LOVES to eat hot open faced roast beef sandwiches with mashed potatoes or french fries so I’ve had to perfect my brown gravy. Because, no one should have to eat it out of a can or a jar. It’s way too simple to make, and is much more yummy. You can also make chicken gravy by substituting beef broth with chicken broth.
