Slow cooker pastrami sandwiches are easy to make. Piled on toasted bread with some spicy mustard and cheese.
Pastrami is made from brisket which is a tougher cut of meat unless it's smoked low and slow until tender and delicious. This is a cheater version that starts off with a brined corned beef.
What is corned beef?
It's basically the first step to delicious pastrami. It’s a brisket brined in pickling brine, which makes it super tender.
Tips for making slow cooker pastrami
- Liquid smoke is optional but highly recommended. You can find it in the spice section of your local grocery store or here on Amazon.
- I usually throw this in the slow cooker before I go to bed then I can do the cooling and heat in the oven the next day for sandwiches.
- If you get a smaller corned beef you will have to adjust the cooking time as 10 hours is too long to cook anything smaller than 4 lbs and it will be dry.
- Rye bread is the traditional choice of bread for pastrami sandwiches, buts it's also delicious on sourdough or even a soft toasted roll.
- If you love sauerkraut on your pastrami sandwich go for it, my family is not a fan so I leave it off.
- Juices will collect in the foil and some in the bottom of the slow cooker. Save it all for later.

To assemble the sandwich

If you're concerned about corned beef being too salty, you can soak the corned beef in cold water for 4 hours, prior to cooking.
