Why This Recipe Works

When I’m looking for the best way to make a meal without lots of work, this recipe is my go to. The prep time is quick because all I have to do is put everything into the crock pot, turn it on, and leave it be for most of the day. By the end of cooking time, the beef has soaked up the flavors and it’s ready to be sliced.

If someone doesn’t want it on sandwiches, it can be served alongside mashed potatoes or even on top. Lay the slices on top of a salad for a healthy meal option, too! This is a meal your whole family will love.

Recipe Ingredients

  • Corned Beef: I suggest purchasing a flat cut 4 lbs. corned beef. It will yield enough for several sandwiches and leftovers. You can use any cut of corned beef such as point cut.
  • Spice Packet: Keep the spice packet that comes with the corned beef.
  • Seasonings: Onion powder, brown sugar, ground black pepper, whole peeled garlic cloves, and hickory liquid smoke make the perfect spice mixture.
  • Beer: You can use any beer but I prefer to use a light beer.
  • Water: Adds to the cooking liquid. (The full recipe is below the photos on the recipe card.)
