Corned Beef is typically beef brisket that has been soaking in a salt brine for a period of time. It is actually called corned beef because the salt that is used to brine is larger-grained, therefore called “corns.” 

The meat tends to be extremely flavorful because of the brining process and has become a staple piece for St. Patrick’s Day. However, if you do smoked corned beef, then you are breaking that norm!

Corned beef is traditionally boiled. While I have fond memories of this, I thought it would be fun to spice things up this year. We are gonna do smoked corned beef over a fire instead! 

Basically, we will smoke the corned beef over a fire until it reaches about 170F internal temperature. Next, we will pull it off and place it inside of some tin foil with some Guinness. It will then go back on the smoker for another hour or two until it reaches 200F. 

Then we will slice into that smoked corned beef and place it on top of some rye bread. Add some Swiss cheese, sauerkraut & dressing to make it the best Corned Beef Sandwich you’ve ever had! 

Pour yourself a pint of Guinness, and you are ready to party!
In the end, holidays like St. Patrick’s Day are about exploring new ways of cooking classic dishes. With this Smoked Corned Beef Sandwich made with Guinness, you will definitely be enjoying what the Emerald Isle has to offer right in your own backyard. Slainte!

Why you’ll love this recipe

These hot Corned Beef Sandwiches are the perfect way to celebrate St. Patrick’s Day or dinner with friends and family! They’re very similar to the Reuben sandwiches you’d find at Ruby Tuesday’s but MUCH BETTER. 

These delicious sandwiches are loaded with tender meat soaked in a Guinness bath and topped with melty Swiss cheese, sauerkraut, Thousand Island dressing, and wedged between rye bread! Another reason why this recipe is fantastic is its ease of customization! You can play around with the seasonings on the beef and the toppings to get your perfect sandwich. 



Smoked Corned Beef

  • Pre-brined Corned Beef Brisket – This can be found in the deli section of your grocery store. Pre-brined brisket is already ready to cook, so there’s no need to brine it yourself. 
  • Black Pepper
  • Onion Powder
  • Garlic Powder
  • Coriander
  • Cayenne
  • Salt
  • Guinness – An Irish stout beer with a deep brown color. We’re adding this to the corned beef in the smoker to impart some flavor into the meat!
  • Beef Broth
  • Yellow Mustard – Adds a nice tangy flavor to the beef. 


  • Thousand Island Dressing – Adds a delicious contrast to the rich, savory flavors of the corned beef.
  • Swiss Cheese – Complements the salty and slightly peppery notes of the corned beef. 
  • Sauerkraut – Fermented, tangy, and provides a vibrant contrast to the meat. 
  • Rye Bread – Slightly earthy and robust with a unique flavor that pairs well with corned beef. 

How to Make a Smoked Corned Beef Sandwich

First off, grab that pre-brined corned beef brisket, but ditch the included seasoning. We’re gonna do something cool to make it less salty. You can totally skip this step if you want, but if you’re down, give the beef a nice soak in water for about 2 hours. After that, pop it back in the fridge.

Next, we’re going to spread some mustard all over the outside of the corned beef and then sprinkle on the black pepper, onion powder, garlic powder, coriander, cayenne, and salt. 

Then, fire up your smoker and wait until it reaches a steady 250F. We’re smoking the beef at a lower temperature so it cooks perfectly all around and becomes super tender.

Now, gently place that corned beef in, fat side down. Let it smoke until it hits 170F inside. It might take anywhere from 1.5 to 3 hours, so grab a drink and chill.

Alright, when the smoked corn beef internal temperature reaches at least 170F, carefully take it out of the smoker. Grab two sheets of tin foil and make a little “boat” with the edges. Next, pour some Guinness Beer and Beef Broth over the meat, letting it pool in the tin foil base. 

Seal it up with the foil cover and get it back on the grill. This time, we’re looking for a toasty 200F inside, which might take another 1.5 to 2 hours. Low and slow wins the corned beef game!

Once it’s hit that perfect mark, take it out and let the meat rest. Wrap it up in aluminum foil and then place it in a cooler. Let it chill there for about 20 minutes.

Serving Time

When the time’s up, get ready to slice. Cut against the grain for maximum tenderness. You can do thick or thin slices, depending on your personal preference. 

To really kick things up, serve it up with some melted cheese, sauerkraut, and Thousand Island dressing between two rye bread slices.

Finally, pour yourself a well-deserved Guinness and enjoy it with friends and family!


  • Feel free to add different toppings than what I have listed. Some great options are horseradish mayo, dill pickle relish, and caramelized onions!
  • Use an instant-read thermometer to ensure the internal temperature of the beef reaches at least 170F.
  • Toast the side of each bread slice for the ultimate crunch!

How to Store Leftovers & Reheat

Store leftover beef in an airtight container in the fridge for 3-4 days. You can also freeze your smoked corned beef for later if you don’t plan on eating it right away! Pop individual portions into an airtight container and keep in the freezer for 2-3 months!

When you’re ready to reheat your refrigerated corned beef, pull out a skillet and heat the slices of beef until warm. This will help the beef crisp up a bit and not be too moist. For a quicker method, you can pop the meat in the microwave for 20-30 seconds with a wet paper towel on top. This helps the meat not dry out. 

You can use these same reheating methods for frozen corned beef, but just make sure to let it thaw overnight in the fridge. 

If you don’t want to make a whole sandwich with the leftover beef, we suggest making some ROAST BEEF AND CHEDDAR SLIDERS!

If you don’t feel like reheating the beef at all, you can also make a cold corned beef sandwich!

What to Serve With Corned Beef Sandwiches

Don’t leave your freakin’ delicious sandwiches hangin’! Pair them with some potato chips, French fries, and even some CHEESY IRISH TATER TOTS for the ultimate St. Patrick’s Day celebration!
