HOW TO MAKE Copycat Firehouse Subs New York Steamer Sandwich

  1. Start with a nice, fresh submarine sandwich bun.
  2. Layer corned beef, pastrami, and provolone on the bottom bun.
  3. Place both sides of the sandwich under the broiler until the cheese is melted and the bread is toasty.
  4. Add mayo and mustard to the top bun.
  5. Squirt Italian Dressing over the cheese, then close the sandwich and enjoy!

HOW TO MAKE ON A BLACKSTONE GRIDDLE

  1. Heat the griddle as per manufacturer directions to medium.
  2. Butter the buns.
  3. Lay the buns on the griddle, buttered-side down, until toasted. 
  4. Warm the meat on the griddle.
  5. Layer the meat onto the sandwich, top with cheese, and cover with a cooking dome to melt the cheese (you can add a squirt of water under the dome to steam the bun and melt the cheese).

MAKE IT A MEAL

Of course, I always love a pastrami sandwich or corned beef sandwich with chips or fries on the side, and this sandwich is no different. But if you’re looking for freshness, this Mexican Street Corn Salad is full of flavor. Or add a little green to your plate with this Broccoli Salad with Bacon, Almonds, and Orange. If you’re craving a soup and sandwich combo, check out Cream of Leek and Green Garlic Soup, Smoked Chicken Tortilla Soup, or Cream of Jalapeño Soup, and wash it all down with this sima recipe for homemade soda!

VARIATIONS FOR THIS PASTRAMI AND CORNED BEEF SANDWICH

I know I’ve said it repeatedly, but once you try homemade pastrami or corned beef, it’s hard to return to the deli version. That said, if you’re craving a Copycat Firehouse Subs New York Steamer sub and don’t have time to make your meats, that’s okay! Go ahead and pick up what you need from the deli and enjoy.

Prefer mozzarella or Swiss cheese? Any mild cheese that will melt well can be used in place of the provolone. And if you don’t like spicy mustard, go ahead and use regular or Dijon instead!

STORAGE

Unfortunately, hot sandwiches don’t keep very well; this one is no exception. The bread will get soggy, the melted cheese will get gloopy, and it won’t be hot and fresh. That’s why I always recommend eating this one right out of the oven or off the Blackstone Griddle!

Honestly, it’s so easy to assemble this sandwich in a matter of minutes, and you wouldn’t save much time making it ahead anyway. Corned beef, pastrami, cheese, bread, spicy mustard, mayo, and Italian dressing all keep well in the fridge or pantry, so they can be ready to go any time.

Not sure you’ll finish a whole sandwich? Just cut the bread in half, store the half you aren’t using, and assemble a smaller sandwich for yourself. That way, you can enjoy the whole thing without worrying about any of it going to waste!
