Check out our smoked corned beef recipe if you want a creative way to make corned beef just for the sandwich. Or you can check out our step-by-step guide on how to corn your own beef.
Reuben versus Pastrami Sandwich
A Reuben is typically a grilled sandwich that is made of rye bread, Swiss cheese, Russian dressing, corned beef and a few other key ingredients. Corned beef is typically made by boiling the beef in some spices until done.
A Pastrami sandwich is made from pastrami, which is smoked corned beef that has been rubbed with spices and topped with similar ingredients (commonly mustard, sauerkraut, and others).
This particular corned beef sandwich is focused on taking leftover corned beef (whether smoked like Pastrami or boiled), and enhancing it with a fantastic Guinness Au Jus dipping sauce made from Guinness, Worcestershire, and corning or pickling spices. So it’s a hybrid of the two styles.
Preparing the Meat
Start by smoking a pre-corned beef cut like brisket or round. We use our smoked Snake River Farms Corned Beef as the starting flavor. Because the predominant flavor of the corned beef sandwich is the meat, this is an important flavor to have and a great use for corned beef leftovers.
Type of Bread For Corned Beef Sandwich
Rye is the best option IMO. Its unique somewhat savory flavor is great and it holds up well to being grilled. Since we’re dunking into a dip, having sturdy bread helps.
Making the Corned Beef Sandwich
- Slice up the corned beef leftovers into thin slices, but not too thin. Be sure to slice the corned beef against the grain.
- Warm up a grill pan.
- Butter the bread on one side.
- Construct the sandwich in layers starting with the Sauerkraut, then corned beef, then mustard, then a pickle.
- Grill each side of the sandwich, butter side out, for about 4 – 5 minutes so it’s crunchy.
- Serve with the Guinness Au Jus.
Making Guinness Au Jus
We love dipping sandwiches in Au Jus. In our French Dip recipe we walk through how to make Au Jus (which is so easy to do). For this recipe we’re making a Guinness Au Jus that is ready in 20 minutes perfect for this corned beef sandwich. Ingredients include:
- Shallots
- Garlic
- Guinness Beer
- Beef Stock
- Worcestershire sauce
- Corning or Pickling Spices
Over a medium heat add a little extra virgin olive oil and shallots. Saute for a few minutes until soft and then add garlic. Stir for an additional minute and then add the Guinness, Worcestershire, Beef Stock, and pickling spices. Bring to a simmer and then simmer at the lowest heat for 20 minutes.
You can do this in advance, it’s great cold, or serve the Au Jus warm.

Ingredients
Corned Beef Sandwich
- 8 slices rye bread
- 2 tablespoons unsalted butter
- 2 pounds leftover corned beef, sliced thin
- 1 cup sauerkraut, drained of liquid
- ¼ cup Dijon Mustard
- 2 whole dill pickles
Guinness Au Jus
- ½ tablespoon extra virgin olive oil
- 1 tablespoon diced shallots
- 1 clove garlic, diced
- 1 cup Guinness beer
- ¼ cup beef stock
- ¼ cup Worcestershire sauce
- 2 teaspoons corning or pickling spices (Most packaged corned beef comes with additional pickling spices. If they don’t, you can buy pre-made pickling spice blends.)
Instructions
Guinness Au Jus
-
In a small sauce pan over medium heat, add the olive oil and shallots. Stir as the temperature rises. Saute in the pan for 6 minutes or until the shallots are soft, but not browned. Turn down the heat if the shallots are cooking too fast. Add the garlic and stir for 1 more minute.
-
Add the remainder of the ingredients to the Au Jus and stir. Adjust heat to medium-high and bring to a simmer. As the Au Jus comes to a simmer, lower the temperature again to the lowest heat that will still allow a simmer for 20 minutes.
-
Remove from heat, strain the au jus into a bowl to remove pickling spices and chunks of shallots. You can make in advance, and store for up to a week and serve cold, or you can serve warm with the sandwiches.
Corned Beef Sandwich
-
Preheat a grill pan to medium heat.
-
Butter one side of each piece of bread and place on the grill pan for 3 minutes or until the bread is toasted. Remove from heat. On the side of one piece of the bread that is not toasted, add the sauerkraut, then about a ½ pound of corned beef, then mustard, and top with sliced pickles. Add the top piece of bread and dunk in the Au Jus and enjoy.
Notes
If the corned beef you use does not have corning spices, there are pre-made pickling spices that are a great substitute.
