The Best Roast Beef Sandwich Recipe – This sandwich is absolutely loaded up with flavor, from the thinly sliced roast beef, to the roasted potatoes, to the horseradish cream, if you want delicious, then this is the sandwich for you.
I’m so guilty of always saying that the simpler food is the better, and for the most part I totally agree with my statement… However, when it comes to the art of the sandwich, the more ingredients the merrier, to me anyways, and this Roast Beef Sandwich Recipe deliver. I’m talking I want an entire garden in between two delicious slices of artisanal bread with some meat. Turkey sandwiches on some wonder bread with mayo is only cool when you’re in college or the day after Thanksgiving, but when you get to play grown-up you’re going to want a big ol’ fat sammich like this Roasted Beef Sandwich packed with goodies and a tasty horseradish cream sauce.
Making sandwiches can be tricky because when you add on a lot of ingredients to it you want to add things that are subtle in flavor and that compliment. While I like blue cheese a lot, sometimes it can overtake the flavor of everything in the dish, so that was a no go for my roast beef sandwich. Trust me, I thought about putting some crumbles on there to, but was worried it would run game on the flavor of this beauty. Even though this roast beef sandwich has a lot going on, the flavors are still incredibly balanced and all complement each other. Now, I just want you to know that you do not need to follow this recipe verbatim, you can certainly do your own variation to make it your own and to eat with flavors you enjoy. What I tried to do is find ingredients I know go well with beef and work from there.
The first thing to decide on is bread. This roasts beef sandwich recipe alone can go 9 million different ways and really there are no bad choices. You can use ciabatta, French, Sourdough, seriously it’s up to you. But, since you are peeping in on this recipe I’ll let you know that I went with a Kaiser roll. I literally only chose this roll because I haven’t had it in a long time. Mind blowing, I know… Next is picking the roast beef. If you were an absolute baller you would roast your own prime rib roast and thinly slice, but most if you won’t be doing that and neither did I. Just for the record though whenever I do roast a prime rib, I always reserve some to do some sort of sandwich. So since most of you won’t be doing that simply ask your butcher or folks up at the deli to slice up some roast beef and a little on the thicker side. I don’t have time for that paper thin roast beef that literally rips apart the second I pick it up, I NEED SOME BEEF FOR CRYING OUTLOUD!!!
Man I need to calm down in this post, you guys are going to think I’m nuts writing about this roasted beef sandwich recipe. Ok so we have our two main components, bread and beef, and now we need to figure out the toppings. Close your eyes and just focus on the beef. Now think of all the amazing things beef goes well with. Potatoes, horseradish, balsamic vinegar, onions, cream, are things that jump right into my head. The next thing is figuring out how to get all of those things that are traditionally served as a sauce over top or a vegetable on the side. Keep reading and I’ll tell you what I did.
I sliced a big russet potato and a sweet potato thin on a mandolin slicer, tossed them in olive oil, salt and pepper, and baked them on a sheet tray lined with parchment paper in the oven at 400° for 20 minutes or until they are lightly browned and cooked. See where I’m goin yet? The next thing I did was sliced 2 shallots really thin on that same mandolin and also placed them on a sheet tray lined with parchment paper. In a bowl I whisked together some balsamic vinegar, sugar and a bit of olive oil and brushed the shallots before baking them in the oven at 400° for 25 minutes. I also went back and basted the shallots every 6 to 7 minutes or so with the balsamic mixture to help intensify the flavor and to caramelize. This also allowed me to kill two birds with one stone. Remember I said beef goes great with balsamic and onions, well I just paired them up.
How to Make the Horseradish Cream:
While there are a few more things on this sandwich, I wanted to mainly talk about the ingredients that require work, like this horseradish cream. So the last thing we are going to look at is the sauce that goes on it. It has a bit going on, but dang is it worth it. Ready?!

Whisk all of those tasty ingredients together in a medium size bowl and you’re good. Promise this horseradish cream is worth it ok? This sauce goes awesome on a ton of different things so be sure to try it out. Now it’s about assembly so stack this roasted beef sandwich recipe high and enjoy it dang it!
