Leftover Roast Beef Sandwiches
These sandwiches are a great way to use up leftover roast beef! Inside buns, there's gravy dipped beef, horseradish sauce & melted Swiss cheese.
Servings: 4 Sandwiches
Equipment
- Large Baking Dish
- Baking Tray
Ingredients
- 600 g Leftover Roast Beef (See Notes)
- 350 g Gravy (See Notes)
- 4 Burger Buns
- 8 Swiss Cheese Slices
- 4 tsp Horseradish Sauce
Instructions
- Preheat an oven to 160°c/140°c fan (320°f/284°f).
- Thinly slice the roast beef, season with salt & pepper then place into a baking dish.
- Next, warm the gravy up in a pan (or in a microwave) then once hot, pour it all over the beef. Cover the dish with foil then bake in the preheated oven for 15-20 minutes, until piping hot.
- When your beef is almost ready, cut the burger buns in half then toast them, either in a frying pan set over a medium heat or under a grill. Once toasted, place the bottom halves onto a baking tray.
- Top each bun (just the bottom half!) with a teaspoon of horseradish sauce then spread it out to completely cover the bread.
- Next, divide the slices of beef between the sandwiches, placing it on top of the horseradish. I'd recommend using a pair of tongs to lift the beef out of the gravy then spoon extra gravy into the sandwiches!
- Top each sandwich with 2 slices of Swiss cheese then place under a grill for a minute or so, to melt the cheese. If you haven't got a grill, bake in the preheated oven for a couple of minutes, or use a blowtorch to melt the cheese.
- Once the cheese is melted, top the sandwiches with the top half of each bun then serve.
Notes
1. Roast Beef - Any type of roast beef will work, I used topside! When making sandwiches, I find that it's best to slice the beef as thin as possible.
2. Burger Buns - I used my roast potato burger buns for these sandwiches but feel free to use whatever type of bread you like.
3. Cooking In An Aga - To cook the beef in an Aga, bake it in the baking oven, on the bottom set of runners. Toast the buns on the simmering plate (on bac-o-glide). To melt the cheese, grill the sandwiches in the roasting oven, as high up as they'll go.
4. Gravy - I used my red wine gravy but you don't have to use homemade! Gravy granules dissolved in boiling water will work as well.
5. Horseradish - You can use a homemade horseradish sauce or a shop bought one. It's up to you!
