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

Best sandwich recipe

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.

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.
