What is pastrami?

When’s the last time you had a hot pastrami sandwich? (So good). But wait … let’s back up. What is pastrami anyway (my kids just asked me)?

Pastrami is meat that is made from beef,  or sometimes from pork, mutton, or turkey. I know …. it tastes so good, right? The flavors come from the way the meat is processed. The raw meat is brined, partially dried, and then seasoned with herbs and spices. The last step is smoking and steaming the meat.

Another party hit are these Hot Pastrami Sliders, served with melted cheese and caramelized onions on pretzel rolls. Yes, please! :)

  1. What a delicious looking appetizer! I’m definitely going to make this for the next gathering where friends are over! Maybe for march madness finals? Thanks so much for sharing! Can’t wait to make these at home. Sauerkraut is such a great addition and almost makes it into a little reuben crostini!

  2. I took these last night to our Couples Supper Club and they were a hit! Thanks so much for the recipe!!

  3. These looks great and I’m supposed to take an appetizer to a party this Saturday. It says the secret is in the mustard…..what’s your favorite to use?

    • Honestly, I go to the “deli” section and ask them, or just pick a flavor or 2 that looks fantastic. The deli section has the best gourmet flavors! Happy St. Patrick’s Day, Gina! xo
