Before you start

Before beginning, ensure your slow cooker is clean and positioned on a level, heat-safe surface near an outlet. Chop the pastrami into small, bite-sized pieces to ensure even distribution. Cut the cream cheese into uniform cubes to facilitate faster melting.

Having all ingredients measured and ready to add saves time and ensures the preparation process is smooth and efficient. Verify that your serving bowl is ready to receive the hot dip once the cooking process is complete.

Ingredients at a glance (4)
  • 1 lb pastrami, chopped
  • 2 tbsp spicy brown mustard
  • 8 oz shredded Swiss cheese
  • 8 oz cream cheese, cubed

Instructions

Layering the ingredients

  1. Layer the slow cooker
    Place the chopped pastrami into the bottom of the slow cooker, ensuring an even layer. Add the spicy brown mustard over the meat, then sprinkle the shredded Swiss cheese and top with the cubed cream cheese.
    Look for The ingredients are layered in the order specified.
    Tip Ensure the cream cheese is cut into small cubes to help it melt evenly into the dip during cooking.

At this stage, the slow cooker is loaded with the pastrami, mustard, and cheeses. Everything is neatly layered, and the slow cooker is covered. Check that the lid is tightly sealed to ensure proper moisture retention during the cooking cycle.

The environment is ready for the slow, steady heat that will transform these simple components into a cohesive, flavorful dip. No further preparation is needed until the cooking time has elapsed.

Slow cooking the dip

  1. Slow cook the dip
    Cover the slow cooker and cook on low for 2 hours. Stir the mixture occasionally if possible to combine the melting cheeses with the pastrami and mustard, ensuring the internal temperature of the pastrami reaches 145°F (63°C). Let the dip rest for at least 3 minutes.
    Look for The dip is bubbly, steaming, and the cheese is completely melted.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Keep the lid closed as much as possible to maintain consistent heat throughout the cooking process.

The dip is currently cooking, and the kitchen should start to smell savory and warm. The cheese is beginning to soften and combine with the pastrami juices. Check the consistency after about one hour of cooking to ensure it is melting evenly. If the dip appears too thick, a gentle stir will help incorporate the ingredients. The goal is a bubbling, hot, and well-integrated mixture that is ready for serving.

Serving the finished dip

  1. Serve the dip
    Once the dip is fully melted, hot, and has rested, transfer it to a serving bowl. Serve immediately while warm to maintain the best consistency for dipping.
    Look for The dip has a glossy, uniform texture.
    Tip Serve immediately while warm to maintain the best consistency for dipping.

The dip has reached the perfect consistency and is ready to be transferred to a serving bowl. It should appear glossy, smooth, and steaming hot. Check that the temperature is consistent throughout the mixture. Once transferred, the dip is ready to be paired with your favorite crusty bread or crackers. Ensure the serving area is set up with appropriate utensils to allow guests to easily serve themselves from the bowl.

Common mistakes

A common mistake is using pre-shredded cheese, which often contains starch that prevents a smooth, velvety melt. Another error is failing to chop the pastrami into small enough pieces, which can make the dip difficult to scoop.

Avoid opening the slow cooker lid too frequently during the cooking process, as this releases heat and significantly increases the total cooking time. Always ensure the slow cooker is set to the correct heat setting to avoid uneven cooking or potential burning.

How to tell it’s done

The dip is done when the cream cheese and Swiss cheese have completely melted and combined with the pastrami and mustard into a smooth, glossy, and uniform mixture. The dip should be steaming hot throughout, with no visible lumps of cream cheese remaining.

Ensure the internal temperature of the pastrami reaches 145°F (63°C) and allow it to rest for at least 3 minutes before transferring it to your serving dish to ensure the best possible texture for your guests.
