How to Make Slow Cooker Pastrami | Easy Crockpot Dinner

- Rinse the Corned Beef: Rinse the 4 lbs. of corned beef thoroughly under cold water to remove excess salt. This helps ensure your pastrami won’t be overly salty.
- Add to Slow Cooker: Place the rinsed corned beef in your slow cooker, making sure it’s nestled in securely.
- Season the Beef: Sprinkle the contents of the spice packet, 1 tsp. onion powder, 3 tbsp. brown sugar, and ½ tsp. ground black pepper evenly over the corned beef. Add the 5 garlic cloves on top.
- Add Liquids: Pour in 12 oz. of beer, followed by 3 cups of water, and 1 tsp. hickory liquid smoke. These ingredients create a flavorful broth that makes the meat succulent.
- Set the Temperature: Cover your slow cooker and cook on LOW for 7-8 hours, allowing the flavors to meld beautifully.
- Rest and Serve: Once finished, carefully remove the corned beef onto a cutting board. Let it rest for about 5-10 minutes before slicing it against the grain. Serve with marble rye, melted Swiss cheese, Thousand Island dressing, and a generous helping of sauerkraut.
Storing & Reheating
To store any leftovers, let them cool to room temperature before transferring them to an airtight container. They can be stored in the refrigerator for up to 3-4 days. If you want to enjoy it later, you can freeze portions for up to 3 months. To reheat, simply place the pastrami in a skillet over medium heat until warmed through, usually around 5-7 minutes. If it seems dry, add a tiny splash of beer or broth to refresh it. Just note that the texture may shift slightly after freezing, but it’s still delicious!
Chef’s Helpful Tips
- When rinsing the corned beef, make sure to do it well; this minimizes saltiness in your final dish.
- For extra flavor, consider browning the corned beef on all sides in a skillet before placing it in the slow cooker.
- Be cautious not to overcook; while it’s hard to ruin this recipe in the slow cooker, cooking on LOW is recommended for optimal results.
- To enhance the smoky flavor, add another teaspoon of hickory liquid smoke at the end of the cooking process before serving.
- If you can, let the cooked pastrami cool slightly before slicing it for easier handling and cleaner cuts.
