A hot roast beef sandwich made with deli meat that’s easy and absolutely delicious.

This roast beef sandwich is warm and inviting with earthy flavors paired with melty cheese.

Best part is, how simple this is to make.

This toasted sandwich is crafted using just a handful ingredients yet it’s packed with flavor. How is this possible? Well, each ingredient builds on the next, creating amazing savory flavor with each bite. I’m not exaggerating one bit.

What exactly makes these ingredients so special?

Let’s break it down.

First thing, is starting with the best quality roast beef you can get. Now, you can make your own roast beef, or you can head to the deli. For this recipe, I used Smith’s roast beef, which is made locally from choice cuts of meats. So, it’s fresh, perfectly cooked, and is already seasoned and smoked for optimal flavor.

Next, choose a cheese that pairs well with roast beef. My go-to cheese to pair with roast beef is Havarti. It’s mild in flavor, melts well and has a subtle quality that adds a buttery richness to whatever you are pairing it with. Other good choices would be Swiss cheese, if you don’t mind something with a bit more of a bitter flavor, or provolone which has a nice mild flavor but it’s not quite as soft as Havarti.

What if you don’t have marsala wine?

You can substitute with red wine, sherry or just leave it out. You’ll loose a bit of flavor if you leave it out so it’s worth a trip to the store to pick some up if you can!

Could you use lettuce instead of arugala?

You could. But. Argula has a naturally peppery taste to it that goes really well with this sandwich. If at all possible, definitely try to use arugula instead of lettuce. A blend of baby spinach and arugala would be ok too as sometimes those are packaged together.

What kind of mushrooms are best?

Any, really! Mini portabellas are delicious but regular white mushrooms are excellent too. You could go for canned mushrooms, but I prefer using fresh so that when you sauté them in the marsala, they soak in that extra flavor.
