Ingredients You’ll Need

- Spice packet that comes with the corned beef: Essential for that classic pastrami flavor; don’t skip this!
- 1 tsp. onion powder: This adds depth and a mild sweetness to your dish.
- 3 tbsp. brown sugar: Balances the savory elements and enhances caramelization during cooking.
- ½ tsp. ground black pepper: This will give your pastrami a nice kick of flavor.
- 5 garlic cloves, peeled but left whole: Adds rich flavor without overpowering the dish; they will soften and sweeten during cooking.
- 12 oz. beer: A flavorful liquid that helps in tenderizing the corned beef and adds a subtle depth of flavor. A good lager or ale works well.
- 3 cups water: Necessary to ensure the corned beef stays moist as it cooks.
- 1 tsp. hickory liquid smoke: Adds a lovely smoky flavor, reminiscent of traditional pastrami.
- Marble rye: A must for serving—its unique appearance and flavor pair perfectly with pastrami.
- Thousand Island dressing: Essential for assembly, providing a creamy contrast to the meat.
- Swiss cheese: Optional, but highly recommended for that classic Reuben vibe.
- Sauerkraut: Adds a burst of tanginess that complements the richness of the beef.
How to Make Slow Cooker Pastrami | Easy Crockpot Dinner

- Rinse the Corned Beef: Start by rinsing the 4 lbs. of corned beef very well under cold running water. This step is crucial to remove excess salt and prepare the beef for maximum flavor.
- Load the Slow Cooker: Place the rinsed corned beef into the slow cooker, ensuring it sits nicely at the bottom.
- Add the Spice Mixture: Sprinkle the spice packet that comes with the corned beef over the top, along with the 1 tsp. of onion powder, 3 tbsp. of brown sugar, and ½ tsp. of ground black pepper. Toss in the 5 whole garlic cloves for that aromatic kick.
- Mix in the Liquids: Pour in the 12 oz. of beer and 3 cups of water, followed by 1 tsp. of hickory liquid smoke. This combination not only adds moisture but layers of flavor.
- Set Cooking Time: Cover the slow cooker and set it to LOW heat for 7-8 hours. This slow cooking method will break down the beef fibers and ensure it’s tender and delicious.
- Rest and Slice: Once done, carefully remove the corned beef onto a cutting board and let it rest for 5-10 minutes before slicing thinly against the grain. This ensures each slice is juicy and flavorful.
Storing & Reheating
Leftover Slow Cooker Pastrami can be stored in an airtight container in the refrigerator for up to 4 days. If you want to keep it for a longer period, freezing is a great option. Wrap the pastrami tightly in plastic wrap and then in aluminum foil or a freezer-safe bag for up to 3 months. When you’re ready to enjoy, simply thaw in the fridge overnight and reheat in the microwave or on the stovetop with a splash of water to retain moisture.
