Hot Roast Beef Sandwiches & Gravy

"This is a copycat version of a dish served by a local diner in central Pennsylvania. My mom & dad used to always go there specifically to order this meal, until my mom finally nailed the recipe. It has quickly become a family favorite and a regular meal that I have to make for DH... This gravy is very flavorful and especially delicious over shoestring french fries!"

  1. What’s the best roast to buy for this


  1. I have a friend who loves open-faced hot roast beef sandwiches from various diners throughout the area. Rather than do yet another carry-out, I looked and found this wonderful recipe that mimics well the type of sandwich served in diners in our area. I used a rump roast and, after 10 hours, it was very tender and yielded over 4 cups broth (I left it fat side up in the crock pot - removed extra fat when it was done cooking). The gravy was good -- however, probably added less than 1 cup flour/water -- and would add even less next time. My friend thought it was excellent (thank you!). I used salt-free bouillon packet -- may try "Better than Bouillon" next time for a bit richer flavor. The crockpot made this really easy (no roasting pan/meat thermometers/etc.) Thanks for posting!
  2. I have made this recipe a couple of times now and I keep coming back to it. It is a definite keeper.
  3. Excellent recipe....I actually had some leftover roast beef from another meal and used that. I say I probably had a pound. I just simmered the beef in the broth until heated through, then made the gravy per recipe by added a little more water.
  4. I love open-faced hot beef sandwiches and this one was simple and good. I started with some leftover beef from another meal and it came together quickly. I'll definitely make this again. Thanks for sharing.
  5. This is simply the best


I am a real estate paralegal who has two great passions in life: writing and baking. I grew up in PA so I enjoy trying a lot of Amish recipes, but my move to the south when I married my hubby has introduced my tastebuds to a whole new world of down-home southern cookin'. I have two beautiful little girls and one very stubborn (but spoiled) Himilayan cat. Always excited to try a new recipe.
