Ingredients You’ll Need

4 lbs. corned beef (flat cut recommended): This is the star of the dish, providing rich texture and flavor. The flat cut is both tender and less fatty.
Spice packet: Most corned beef comes with a spice packet—this is key for that distinctive pastrami taste.
1 tsp. onion powder: This adds an aromatic flavor that enhances the overall dish.
3 tbsp. brown sugar: Balances the saltiness of the beef and caramelizes beautifully during cooking.
½ tsp. ground black pepper: A basic seasoning that brings out the flavors of the meat and spices.
5 garlic cloves, peeled but left whole: Infuses a mild garlic flavor without overpowering the dish.
12 oz. beer: I recommend a lager or ale for a delicious depth. You can substitute with beef broth for a non-alcoholic version.
3 cups water: This helps regulate the cooking environment within the slow cooker to maintain moisture.
1 tsp. hickory liquid smoke: Adds a smoky punch, reminiscent of classic deli pastrami.
Marble rye: The perfect bread for sandwiches; its texture complements the pastrami wonderfully.
Thousand Island dressing: A classic pairing that adds tangy creaminess to your sandwich.
Swiss cheese: Melts beautifully and pairs perfectly with the richness of the pastrami.
Sauerkraut: Adds a delightful crunch and acidity—perfectly balancing the richness of the meat.

How to Make Slow Cooker Pastrami | Easy Crockpot Dinner

Rinse the Corned Beef: Rinse the corned beef very well under cold water. This step helps remove excess salt and brine.
Add to Slow Cooker: Place the rinsed corned beef into your slow cooker, fitting it snugly.
Season: Sprinkle the spice packet, onion powder, brown sugar, and black pepper over the meat. Toss in those whole garlic cloves too.
Pour in Liquids: Add the beer, three cups of water, and hickory liquid smoke over the top. This liquid will keep the meat moist and add flavor.
Set & Cook: Cover and cook on LOW for 7-8 hours, or until the meat is fork-tender and flavorful. Your kitchen will smell divine!
Rest and Slice: Once done, carefully remove the corned beef and let it rest for 5-10 minutes on a cutting board. Slice against the grain and serve.

Storing & Reheating

To store your leftover slow cooker pastrami, place it in an airtight container in the refrigerator for up to 4 days. If you need to keep it longer, it freezes beautifully for up to 3 months—just ensure to seal it tightly to prevent freezer burn. To reheat, simply thaw in the fridge overnight and warm it gently in a skillet or the microwave until heated through. The meat can become a touch drier when reheating, so adding a splash of broth can help to refresh its juiciness.

Chef’s Helpful Tips

Make sure to rinse the corned beef thoroughly to remove excess saltiness.
Feel free to adjust the spices based on your taste; a little extra black pepper can really boost the flavor.
Allow enough time for resting the meat post-cooking; this helps redistribute the juices for a tender slice.
If you’re making sandwiches, toasting the bread adds a wonderful crunch and contrast.
Consider making it a day in advance; the flavors meld even better overnight in the fridge.

This slow cooker pastrami is not just about cooking; it’s an experience that invites warmth, family, and delicious meals into your home. Each bite is a reminder of how simple ingredients can combine to create something unforgettable. I encourage you to give this recipe a try and explore how delicious it can be—whether you’re serving it at a casual get-together or savoring it quietly at home.

Recipe FAQs

Can I use a different cut of beef for pastrami?

Absolutely! While corned beef is traditional, you can use brisket or even top round. Just keep in mind that cooking times may vary based on the cut and size.

What type of beer is best to use?

A lager or pale ale works well, complementing the spices without overpowering the dish. If you prefer not to use beer, using beef broth or cider is a great substitute!

How do I know when the corned beef is done?

The best indication is when it’s tender enough to pull apart with a fork. This usually takes about 7-8 hours on low. You can also check the internal temperature; it should be around 190°F (88°C) for optimal tenderness.

Can I make this recipe ahead of time?

Yes, this is a fantastic make-ahead dish! You can prepare everything in the slow cooker the day before and simply reheat it on low when you’re ready to serve. The flavors only get better as they sit!
