This roast beef sandwich gets its bite from Maille Dijon and quick pickled red onions. Deli roast beef, arugula, and crusty bread turn those five ingredients into a lunch or no-cook dinner in about five minutes.
Why the Pickled Onions Matter
Roast beef and Dijon are rich and savory. Pickled red onions add a sharp bite that keeps the sandwich lively, and a handful of arugula brings a little peppery crunch. Drain the onions before adding them so the bread doesn’t soak up their brine.
Open up my refrigerator and you’ll be sure to find that I always have Maille Dijon Originale Mustard on hand, it’s a must-have staple in my kitchen, and it has the ability to add depth of flavor to savory dishes. With a creamy texture, this robust Dijon will enhance your dishes from sandwiches and marinades to appetizers, soups, and more.
When added to this easy-to-make sandwich, Maille Dijon Originale Mustard takes your meal from it tastes good to oh wow, amazing!

What you’ll need:
- Roast Beef from the deli
- Maille Dijon Originale Mustard
- Pickled Red Onions
- Arugula or baby mixed greens
- Baguettes, ciabatta, or your favorite artisan sandwich bread
Choose Bread That Can Hold the Filling
A baguette or ciabatta has enough crust to hold the roast beef and onions. Another sturdy bread works, too. Serve the sandwich right after you make it.
Freshly sliced red onions will give you more bite; caramelized onions make a sweeter sandwich and take extra time to prepare. If you need a batch of pickled onions, use our quick pickled red onions.
