How to Make the Best Cold Roast Beef Sandwich

Simple Sandwiches/Wraps Recipes

Tired of always eating your leftover roast the same way? I always just cut whatever was left over and used it as deli meat. Don’t get me wrong, I love a good deli sandwich but sometimes it just needs a little more zing. So I set out to find the best way to make a roast beef sandwich that was still easy but oh so delicious.

I love it when I have a recipe that makes 2 meals. Do the work once, but eat twice- and have it be two completely different meals. Like my tender crockpot roast beef does this exact thing for me.

We eat it for dinner the one night, and then I can use the left overs to make a roast beef sandwich for lunch or even for dinner! 

This isn’t your typical  cold roast beef sandwich with horseradish and mustard. Because honestly? I hate both of those. Also, what kid is going to eat that? Not my kids anyway!

So instead of using those typical ingredients for a roast beef, I improvised and used my own sauces to bring you the best roast beef sandwich ever!

I’ll give you a step by step tutorial, but really it is so simple you don’t even need it. This is another 5 minute recipe.


Step by Step on How to Make the Best Roast Beef Sandwich

Before we really get into the ingredients for this sandwich, first decide on what bred you are going to use! I love making mine on a bagel. It honestly just makes it so much more delicious than just regular sandwich bread. Use rye or sourdough if you don’t have bagels on hand.

Cut the bagel in half (or have two slices of whatever bread you will be using) and spread 1 tbsp cesar dressing on each half. Add 3 slices of thickly cut roast beef, and top with ranch dressing, tomatoes and cheese. Add lettuce and replace the top.

Cut in half with a sharp serrated knife. I love using this knife! I’ve had mine for over 5 years and it still works perfectly. I use it many times a day because it gives me that perfect cut. 

See how insanely easy that was? Generally I make this sandwich for my husbands lunch, but pair it with one of these soups or a salad, and you’ll have a great light dinner.
