Get ready for the recipe for the juiciest, the biggest, and the most mouthwatering Pastrami-Sandwich New York Style you can prepare at home! A Pastrami Sandwich is an NYC classic and becoming more popular in Germany. It’s no wonder, as a lot of pastrami is stacked on delicious rye bread and spread with mustard cream cheese. The pastrami sandwich is topped with caramelized onions and cheddar cheese and baked in the oven or an air fryer*. It’s a pretty juicy and tender sandwich, so one or two salt-dill pickled cucumbers are enough to go with it. You can serve it with coleslaw or potato chips and enjoy it.
