How to Make the Best Roast Beef Sandwich Ever
Making the best roast beef sandwich ever 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 roast beef sandwich beauty.
Even though this roast beef sandwich has a lot going on, the flavors are still incredibly balanced and all complement each other and it is seriously the best ever!
Now, I just want you to know that you do not need to follow this roast beef sandwich 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 to create this Roast Beef Sandwich.
Bread for the Roast Beef Sandwich
The first thing to decide on is bread for this roast beef sandwich.
This roast 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 roast beef sandwich recipe I’ll let you know that I went with a Kaiser roll.
I literally only chose this roll for the roast beef sandwich because I haven’t had it in a long time. Mind blowing, I know…
What Kind of Roast Beef to Use in a Sandwich
Next is picking the roast beef for the roast beef sandwich.
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 roast beef 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 for your roast beef sandwich.
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 OUT LOUD!!!
Roast Beef Sandwich Toppings
Man I need to calm down in this post, you guys are going to think I’m nuts writing about this roast beef sandwich recipe.
Ok so we have our two main components, bread and beef, and now we need to figure out the roast beef sandwich toppings.
Close your eyes and just focus on the beef.
Now think of all the amazing things beef goes well with and what would make this roast beef sandwich epic!
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 of the roast beef sandwich.
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.
You know potatoes go great with beef and they are going to be amazing on this roast beef sandwich.
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.
Caramelized onions and beef! You clearly have to see what’s going down with this roast beef sandwich or else you’ve just completely missed it.
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 on the toppings for this roast beef sandwich recipe.
Remember I said beef goes great with balsamic and onions, well I just paired them up.
How to Make a Horseradish Cream
While there are a few more things on this roast beef 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 the roast beef sandwich.
It has a bit going on, but dang is it worth it. Ready?!
Mayo, sour cream, cream cheese, fresh grated horseradish, chiffonade basil, chopped chives, parmesan cheese, salt and pepper, and Worcestershire sauce.
Whisk all of those tasty ingredients together in a medium size bowl and you’re good and smother it onto the roast beef sandwich.
Promise this horseradish cream is worth it ok?
