Hot Beef Sandwiches with Mashed Potatoes and Gravy are an open-faced sandwich that is pure comfort food. White bread is toasted, covered with mashed potatoes, leftover shredded pot roast and gravy. It’s an easy way to turn leftover pot roast into a hearty and delicious meal.
Made With Leftover Pot Roast
Next time you make a pot roast, plan on making these gravy-drenched sandwiches a few days later. The whole family will rave over them. I recommend using this Pot Roast with Root Vegetables recipe, but you can use any leftover pot roast. Just be sure you save 1/2 cup of the gravy or pot roast juices to make the gravy for these sandwiches. If you don’t have quite enough extra gravy, increase the amount of beef broth and butter in the recipe.
The leftover pot roast gets shredded up and added to the gravy. It’s so delicious! Pot Roast seriously never tasted so good!
Tips For Making Hot Beef Sandwiches with Mashed Potatoes and Gravy
- Use Texas Toast if you can find it. If not, any white bread will do. Whatever you use, be sure to get it golden and buttery before covering it with mashed potatoes.
- To save time you can use refrigerated mashed potatoes instead of making homemade.
- I love to flavor the gravy with rosemary, but leave it out if you don’t like rosemary or replace it with a little thyme or parsley.
If you’re a meat and potatoes kind of person, these Hot Beef Sandwiches are a home run! You have all your favorites combined into one delicious sandwich. This is one of these meals where leftovers are more looked forward to than the first go around.
