1 tsp. onion powder: Adds a hint of sweetness without overpowering the other flavors.
3 tbsp. brown sugar: Balances the saltiness of the beef and complements the spices beautifully.
½ tsp. ground black pepper: Just enough to add a warm background kick.
5 garlic cloves, peeled, but left whole: They infuse the meat with flavor as they soften during cooking.
12 oz. beer: A stout or lager works best; the richness adds depth to the flavor.
3 cups water: Keeps everything moist in the slow cooker.
1 tsp. hickory liquid smoke: For that deep, smoky flavor reminiscent of a BBQ joint.
Marble rye: Perfect for serving, it brings a unique taste and texture to the meal.
Thousand Island dressing: Adds creaminess and a touch of sweetness, a classic complement for pastrami.
Swiss cheese: Melts beautifully and adds a subtle nuttiness that enhances the sandwich experience.
Sauerkraut: Adds a tangy crunch that perfectly balances the richness of the meat and cheese.

How to Make Slow Cooker Pastrami | Easy Crockpot Dinner

Rinse the Corned Beef: Begin by rinsing the corned beef very well under cold water. This step is crucial as it helps to remove excess salt that can overwhelm the dish.
Add to Slow Cooker: Place the rinsed corned beef into your slow cooker, fitting it snugly.
Season it Up: Sprinkle the spice packet over the corned beef. Then, add the onion powder, brown sugar, and ground black pepper. Nestle the whole garlic cloves around the beef.
Pour the Liquid: Gently pour the beer and water over the beef. Finally, drizzle the hickory liquid smoke for that essential BBQ flavor.
Set to Cook: Cover the slow cooker and set it to LOW for 7-8 hours. Your house will smell amazing, so prepare for the anticipation to build!
Slice and Serve: When the cooking time is up, carefully lift the corned beef out of the slow cooker and place it on a cutting board. Let it rest for about 5-10 minutes before slicing thinly against the grain. Serve with marble rye, Thousand Island dressing, Swiss cheese, and sauerkraut for a deliciously satisfying meal.

Storing & Reheating

If you find yourself with leftovers (which is often the case), let the pastrami cool completely at room temperature, then transfer it to an airtight container. It will keep well in the fridge for up to 4 days. For long-term storage, you can freeze the sliced pastrami for up to 3 months. When ready to enjoy, reheat it in the microwave or a skillet over low heat until warmed through. Just note that the texture might change slightly upon reheating, but a little splash of broth can bring back the moisture.

Chef’s Helpful Tips

Avoid overcooking the corned beef; it should be tender yet easy to slice without falling apart.
Use a meat thermometer for best results; the internal temperature should reach about 190°F for perfect slicing.
To elevate flavors, consider adding a few peppercorns or bay leaves in the slow cooker.
If you prefer a bit more smokiness, amp up the liquid smoke a notch, but go easy—you want to enhance the flavor without overpowering it.
Make it a day ahead! Slow cooker pastrami tastes even better the next day, as the flavors have more time to meld together.

Slow Cooker Pastrami is not just a meal; it’s an experience that transforms any day into something special. It’s simple to prepare, packed with flavors, and serves generously, making it perfect whether you’re indulging solo or feeding a crowd.
