With just two ingredients and a hands-off cooking method, this pastrami couldn’t be an easier main course.
The total package! It’s economical as far as meat is concerned, features just two ingredients (plus the meat), and is super crowd-pleasing. I got this recipe from a friend years ago and I can’t begin to tell you how many people it’s been shared with. It’s become a favorite staple in so many homes.
There’s no specific time when you can prepare and serve this. You can cook it all day and serve it during the week or save it for Friday night .
I haven’t tried it in a Crock-Pot if you want to serve it Shabbos day, but who knows, that might work! If you make it during the week, you can wrap it up and add it to your cholent once it’s already cooked.

Ok, let’s make this. It couldn’t be simpler. You’ll want to choose the Navel Pastrami that comes in the vacuum-sealed bag.
The Navel Pastrami that comes in a vacuum-sealed bag is fatty and pre-cooked. You can also find stores that cut a large roast into chunks if you don’t want such a large piece. This recipe works with those smaller chunks too!

In a small pot, combine the brown sugar and mustard. (Editor’s Note: We also tried simply combining the brown sugar and mustard in a bowl, without cooking in the pot, and pouring it over. We found that the results were similar.)

Remove the pastrami from the bag and place in a 9×13-inch pan. Pour sauce on top.

This will cook low and slow for 6-8 hours, but when it’s done, just slice it up into chunks and serve with the sauce!
That looks good!

It freezes well too! Just cover it tightly and freeze in the sauce. Remove from freezer and warm up (covered tightly) in oven. This can sit in the oven on a low temperature for a long time.

Keep that extra sauce for serving on the side (why not?)

Looks amazing! Any options for those of us that don’t have the “heart” to eat navel pastrami? Can it work with another cut of pastrami roast? Thank you!
Looks really good! Plan on trying it…
Please can you come up with a Kosher LePesach option, to bake navel pastrami with a mustard free sauce.
Thanks!!
Bake it at what temperature?
Does it have to specifically be navel??
Will this work with something like London Broil or other roast types?
Can I use corned beef? And pour the sauce on top before serving?
Any mustard free sauces?
