How to Make Slow Cooker Pastrami | Easy Crockpot Dinner

- Rinse the Corned Beef: Start by rinsing the 4 lbs. corned beef thoroughly under cold water. This crucial step helps remove excess salt, giving you a balanced flavor.
- Add to Slow Cooker: Place the rinsed corned beef into your slow cooker, making sure it fits snugly.
- Season It Up: Sprinkle the spice packet that came with the corned beef, along with 1 tsp. onion powder, 3 tbsp. brown sugar, and ½ tsp. ground black pepper over the meat. Nestle in the 5 whole garlic cloves for an aromatic boost.
- Liquids Matter: Pour in 12 oz. beer, 3 cups water, and add 1 tsp. hickory liquid smoke to introduce fantastic depth of flavor. The beer helps tenderize the meat while adding a nice caramelization.
- Let It Cook: Cover your slow cooker and set it to cook on LOW for 7-8 hours. The long, slow cooking time ensures the meat becomes incredibly tender and flavorful.
- Rest and Slice: Once cooked, carefully transfer the corned beef to a cutting board. Let it rest for 5-10 minutes to hold onto its juices. Then slice against the grain for the best texture, and serve!
Storing & Reheating
To store leftovers, place any cooled pastrami in an airtight container and refrigerate for up to 4 days. If you wish to keep it longer, feel free to freeze it for up to 3 months in a freezer-safe bag, remembering to squeeze out as much air as possible. When reheating, gently warm slices in a skillet or microwave until heated through—about 1-2 minutes on a low setting. Keep in mind, that reheating may alter the texture slightly but, you can refresh it with a bit of extra sauce or dressing.
Chef’s Helpful Tips
- Avoid overcooking: Make sure to follow the recommended cooking time. Overcooking the pastrami can make it dry, while too little cooking time may leave it tough.
- Use quality beer: A good quality beer complements the dish significantly. Aim for a lager or malty beer for richer flavors.
- Serve immediately: Once cut, serve the pastrami as soon as possible. It’s best enjoyed fresh and warm!
- Extra flavors: Feel free to experiment with additional spices or even Worcestershire sauce for added depth.
- Make-ahead magic: Prep the corned beef and spices the night before. Pop it in the slow cooker in the morning for an easy dinner.

Recipe FAQs
Can I use something other than beer?
Absolutely! If you prefer a non-alcoholic option, feel free to substitute the beer with extra beef broth or apple cider for a touch of sweetness.
How do I know when the corned beef is done?
The best way to check for doneness is to use a meat thermometer. You want the internal temperature to reach about 190°F for perfectly tender slices. If you don’t have a thermometer, the meat should be easy to shred with a fork!
Is this recipe gluten-free?
It can be, but you’ll need to swap the beer with gluten-free beer or broth and ensure your bread and sauerkraut are also gluten-free. There are many tasty options available nowadays!
What sides pair well with Slow Cooker Pastrami?
This dish is incredibly versatile! Serve with crispy potato chips, a hearty coleslaw, or even a simple side of pickles to bring out the flavors. Enjoy with a refreshing salad for a balanced meal!
