Rosemary Garlic Beef Roast

We are to the end of our cow that we had butchered and I have a few roasts and a few steaks left... While I enjoy my normal roast recipe, I'm always game to try something new. The gravy with this recipe was super simple to throw together and we all enjoyed using it with our roast and the rice that I served on the side.
