Hot Roast Beef Sandwiches

What is it about this time of year that makes me want to make big batches of stuff to hand out? Take for example these hot roast beef sandwiches with pepper jack cheese sauce – I want to make a bunch of these to give to carolers that might randomly show up at our house to sing Christmas songs. I would be like. “Oh, that’s so nice! What do I have to give you as our thanks? Oh, here we go — how about some hot roast beef sandwiches that have been warming in the oven? They have an oozy, creamy pepper jack cheese sauce – they’re delicious!” Then I would hand out the individually wrapped sandwiches while a chorus of ‘thank yous’ rings all around.

Okay, so that probably won’t happen – I can’t remember the last time carolers showed up (does anyone still do that?) – but there are lots of other good reasons to make these sandwiches. Maybe for those nights when there’s too much going on to sit down for an actual dinner. These can be made up fast and kept in the oven – everyone can just grab one and go. Or, maybe for tailgating? They could be kept warm in one of those bag warmers until it’s time to serve them from the back of a car. Or, they can be made ahead and reheated for lunch – I love a hot sandwich for lunch. So you see, they’re not just for Christmas carolers.

Some Ingredients You’ll Need

  • Good roast beef from the deli: you’ll need about a 1/2 pound is good for 4-6 sandwiches – and ask for it thinly sliced.
  • Soft rolls: I used onion rolls, but any rolls you like will do!
  • Pepper jack cheese plus some butter, flour, and milk to make the cheese sauce.
