What’s not to love about a Roast Beef Sandwich?

Picture it, is the 1940’s and you’re young and in love so you get married. The wedding is finished and you and your wedding attendants head over to the pool hall for the reception. You sit down with a with a glass of beer and a juicy roast beef sandwich in a homemade bun. It’s dripping in goodness, so you have to shove a paper napkin down your dress, so you don’t get that wedding dress dirty. Oh and there’s definetely some jazz being played in the background.

My grandparents had this recipe from way back in the day, served it at their anniversary and have passed it on to their kids and grandkids. It’s one of the most coveted recipes in my box because grandpa actually signed off on it’s amazingness! This historic and nostalgic dish has its roots as a traditional English dish from the 1700’s – there’s even a song called “The Roast Beef of Old England”!

Chuck Roast is a larger cut of meat that can be used in pot roast, beef stew, etc. and it is cut from the shoulder area of the cow. Beef Roast on the other hand, is cut from the rear legs of the cow. While both taste great, Chuck Roast is more fatty while Beef Roast is more lean.

Tips for making these scrumptious Roast Beef Sandwiches

  • Cook the meat up, store it in a gallon freezer bag, label it, and freeze it for busier times around the house or farm (make sure to thaw it either in the refrigerator or cool water bath – not just out on the counter). Then all you need is a fresh loaf of bread, buns, or heck even serve it over a heaping pile of mashed potatoes.
  • Don’t toss the juice! The juice is the best part! If you still have some left after all of the meat is gone, use it in a soup or as the liquid in your next casserole.
  • Speaking of juice, when serving a hot sandwich, you could also put the juice in individual cups to dip the sandwiches in!
