While I still had some of the leftover roast beef the other week, I made sure to make a few roast beef grilled cheese sandwiches! This has to be one of my favourite ways to enjoy roast beef leftovers and it gave me the perfect opportunity to update this recipe and to add a new photo (see above). Although simply throwing the roast beef into a sandwich with some cheese and grilling it would be great, I like to add sauteed onions and peppers to bring in some new flavours and textures. There are a lot of cheeses that go really well in this sandwich such as swiss, provolone, mozzarella and this time I went with a sharp cheddar. Of course a touch of horse radish is always welcome and if you have any gravy left over from the roast beef dinner, adding a bit inside the sandwich is good and then serving the rest for dipping is even better! Leftover roast beef is such a magical thing!
Roast Beef Grilled Cheese Sandwich with Caramelized Onions, Peppers and Horseradish
Moist and tender roast beef with sauteed onions and peppers in a grilled cheese is a truly decadent way to enjoy your leftovers! A touch of horseradish gives this sandwich a bit of bite and if you have any gravy leftover feel free to use it for dipping!
- 1/2 tablespoon oil
- 1/4 onion (sliced)
- 1/4 bell pepper (sliced)
- 1 tablespoon salted butter, room temperature
- 2 slices bread (gluten-free for gluten-free)
- 1/2 cup swiss cheese (provolone or mozzarella), shredded (or 2 slices), room temperature
- 2 ounces roast beef, warm
- 1/2 tablespoon horseradish
- 1 tablespoon gravy, warm
- Heat the oil in a pan, add the onion and bell pepper and saute until tender, about 5-7 minutes.
- Butter the outside of each slice of bread, sprinkle half of the cheese on the inside of one slice of bread, top with the roast beef, onions and peppers, horseradish, and gravy, the remaining cheese and finally the other slice of bread.
- Grill in a pan, preheated over medium heat, until golden brown on both sides and the cheese has melted, about 2-4 minutes per side.

You always seem to cook what I'm craving! Try this if you have any more roast beef – make a grilled cheese using the beef with pepper jack cheese. On sourdough. Makes me drool. Love your recipes, Kevin.
That's seriously awesome!
That looks SO good!
Wish I had some of that sandwich here!
I love how stuffed this sandwich looks. Grill the cheese and pile on the beef. Sounds like a good idea to me.
I love how yummy your bread always looks! I love roast beef sandwiches!

Now I'm hungry. Looks delicious.
Roast beef is my favorite deli meat, but oddly I've never had it on a hot, grilled sandwich! Great idea, this looks like a delicious combination.
