Where To Find Wagyu Pastrami

We love making things from scratch, no doubt

But, if you’re like us, you don’t have 10 days to make pastrami at home. And you REALLY don’t have time to locate Wagyu beef and turn it into pastrami.

EXPERT TIP: If you’re wanting to make the best of the best, order your wagyu pastrami from Gourmet Food Store. You’ll get an 8 lb cut of meat that has been brined for days, smoked for hours, and steamed to perfection for hours. It’s going to cost a little extra, but the end result is phenomenal.  The pastrami freezes beautifully, too.

Where To Find Jewish Rye Bread

It is important to stress that you can find quality pastrami at many top-notch delis around the globe. Following this recipe with decent pastrami will give you an amazing sandwich.

It’s also important to know that you can find really great rye bread in most well-stocked supermarkets and at quality bakeries around the globe. Again, give you a great sammy!

But, if you want to ensure you’re Jewish rye bread is about as good as you could possibly find, then order a loaf or two from Zimmerman’s Bakery.

You’ll get a beautiful crunchy crust on the outside, and a flavorful pillowy inside. Amazing!

How To Heat the Pastrami

If you have whole pastrami, i.e., from Gourmet Food Store, you’ll want to heat the meat before serving. Give yourself a few hours for this.

Simply remove the meat from the plastic and place it in a large pot with enough simmering water to submerge the whole pastrami. Simmer on medium for 3 hours. Carefully remove and use a large sharp knife to cut the meat into thin slices.

To reheat pre-cut pastrami, or even to amp up the flavors of the slices you’ve just cut from the heat whole pastrami, try the following:

In a medium saucepan, add 1 can of dark beer and 4 tablespoons of whole-grain mustard. Bring to a boil, slightly lower the heat, and then add the pastrami slices. Simmer for about 3 minutes. This step isn’t completely necessary, but beautifully heats the slices and adds another layer of amazing flavor.

What To Put on a Pastrami Sandwich

This pastrami sandwich recipe is keeping it simple. Just like they do at the legendary Katz’s Delicatessen in New York City.

Take your rye bread slices and slather on a good helping of brown mustard (we love the spicy variety).

Now, layer slices of the hot pastrami on top of one slice of bread. Don’t be shy, you’ll want at least a couple of inches of meat piled high.

Wagyu Pastrami Sandwich FAQs

  • What’s the best way to slice whole pastrami? We highly recommend using a nice sharp knife. Try not to cut thick slices. You don’t need to cut one full slice each time you cut through the meat. Turn the knife to an angle and cut off slivers. The slices in our photos here are as big as you’d want. You can have them sliced with a deli meat slicer, but we find you get better results with hand-cut slices. 
  • Can the pastrami be served cold or at room temperature? Of course! We prefer a hot pastrami sandwich, but all that amazing flavor will still be there when serving chilled or at room temp. You can place the sliced meat on a platter and let guests build their own sandwiches!
  • What are other types of bread can be used? Jewish rye bread is definitely traditional, but you’ll still have great results with pumpernickel, sourdough, whole grain, or even good ole country white bread.

When To Serve and How To Store

This sandwich is truly something special. It’s amazing for any occasion, but we love having friends over to watch the big game and serve these. The fun is letting them build their own epic sandwich.

New York-style pickles can be found in the deli section of most well-stocked supermarkets and are must to have on the side. We love serving with homemade coleslaw, potato salad, and/or Kettle chips.

EXPERT TIP: If you’ve ordered the Wagyu pastrami from Gourmet Food Store, chances are you’ll have plenty of leftovers. Wrap the cut of meat, whole or in slices, in butcher paper or parchment paper, and then wrap in foil. The meat freezes beautifully for up to 2 months. Leftovers will keep in the fridge for a week.

So amazing!
