Growing up in my husband’s Irish household, his family would often buy a pre-corned brisket flat, boil it in water with some spices and cabbage, and then simply serve it with potatoes. While a great nod to tradition, let’s just say that there are a lot of ways to add more flavor to this traditional dish — like smoking.

Corning Beef Versus A Brine

Smoked corned beef starts with a brine. Corning is simply a brining process with specific spices that allow the meat to cure. The brine is a salt solution that the meat sits in, and through osmosis the salt and spices are absorbed into the meat. The salt is typically a curing salt (Prague Powder 1), which is what gives the meat its signature reddish color.

The red color comes from the type of curing salt used.

If you go to the store and purchase a “corned beef” you will see that the meat is typically still packaged in some of that solution. Other ingredients you may see include; peppercorns, mustard seed, allspice, and other ingredients you would see in classic pickling brines.

Cuts of Beef

Typically the brisket flat is the common cut used for corned beef. You may also see beef round as we highlighted above. Either cut is going to be delicious. To make the process for this particular recipe easy grab a cut that has already been corned like these great corned cuts from Snake River Farms. Both of those cuts are best with a slow cooking process. Smoking corned beef (on a smoker or grill) is the perfect way to prepare these cuts versus braising (or boiling). You’re going to get so much more flavor out if it this way!

Why do we highlight two cooking styles? It’s because both cuts of meat are best served when they are cooked to two different internal temperatures. Round is like any roast (Prime Rib as an example) and is great and tender medium rare. Brisket flat is best when taking to a much higher finishing temperature to allow the tough intramuscular tissue break down.

Corned Beef Round

When we are smoking beef round, the roast is typically 8 – 10 pounds (like this round from Snake River Farms). We recommend you cook to medium rare in this case, then slice thick for a classic dinner presentation, or thin slices for sandwiches. Add a simple rub that is light on salt (because the corned beef is going to be inherently salty from the brine) and then smoke at 250 degrees Fahrenheit using fruit wood. It should take about 4 hours to cook to medium rare (or 135 degrees F).

Corned Brisket Flat

You can check out this smoked brisket post on the various parts of a brisket. The most common pre-corned cut you will find is a small 2 – 4 pound brisket flat, which is perfect portions for 4 – 6 people. When smoking a brisket flat, it’s slightly different than a whole packer.

Start at a temperature of 250 degrees Fahrenheit, using fruit wood or oak. Smoke for five to six hours until the internal temperature ranges from 190 to 210 degrees F. This is just like any brisket cook, however the flat being smaller will cook much faster. If you just want to slice it for sandwiches you can also target 180. It will still be tender, but the texture won’t quite be as tender as going to the higher temp.

The meat probe should insert like butter into the flat similar to smoking a normal brisket. The best way to measure the temperature is using a remote temperature probe like the Thermoworks Smoke Unit. We go into much more detail on our article about making your own brine and smoking a brisket flat.

Soaking The Meat

One of our readers asked about whether a pre-soak of the corned beef is needed to extract some of the salty flavor. This is going to be optional based upon your taste preference.

  • No Soak – If you elect not to soak, then the concentration of all the brine remains in the meat and the flavors and salt component stand out. We love salt, and so we do not soak, nor recommend it for this recipe.
  • Soak – Soaking the meat in cold water will allow the water to pull some of the salt out of the meat. Almost like a reverse brine. Simply place the meat into a large container and completely cover with cold water. Keep in the fridge. After 2 hours, discard the water. For smaller cuts under 4 pounds, that should be enough time to tame the salty flavor and its time to season. If you have a large cut like an 8 pound round roast, then do this 2 times at 3 hours. And it’s best to do this the day before the cook.

Be sure if you soak to discard the water as it’s now contaminated from the raw meat.

How To Smoke Corned Beef Round

  1. Preheat smoker targeting 250 degrees F in the cooking chamber. Fruit wood gives a nice sweet flavor. Oak is also a great option.
  2. Start by rinsing the roast with cold water and patting dry. This removes any excess brine and brine ingredients.
  3. Lightly season the meat. Warning: If you have a rub that is salty, it will really stand out. Consider using a homemade rub that is lighter on salt and heavier on other flavors.
  4. Place the roast on the smoker and insert a remote probe thermometer like the Thermoworks Smoke Unit to watch the internal temperature.
  5. Continue to smoke until the internal temperature reaches 135 degrees F for medium rare.
  6. Remove the roast from the smoker and let rest for 30 minutes. This allows carry over cooking to occur and will let the cells cool and reabsorb some of that moisture and flavor.
  7. Slice and serve with your favorite sides.

Pastrami versus Corned Beef

Smoked Corned Beef can be considered pastrami. However your classic pastrami has specific spice blends in the rub consisting of herbs and paprika. After the smoking process, pastrami is then steamed. So for an authentic pastrami, there is that extra seasoning and steaming that gives it that flavor and texture.

Smoked Corned Beef Round

  • Preheat smoker to 250 degrees F using fruit wood like cherry or apple.
  • Remove from the packaging and discard excess liquid. Trim off any excess fat from the exterior of the round and then pat dry with a paper towel. Season with pepper and kosher salt. We use 1 part salt to 2 parts coarse black pepper to season because the round is so much larger than a brisket flat. Don't over salt as the corning brine will be salty.
  • Smoke the round for four hours or until the internal temperature at the thickest part of the roast reaches 135 degrees. Remove from smoker and let rest for 30 minutes.
  • Slice against the grain. On a round there are two directions to the grain, so you'll want to adjust the round as you continue to slice.
  • Serve with your favorite sides.


Brisket Flat: For a brisket or to make your own brine/cure, you can follow our instructions for a smoked corned beef brisket flat.
Seasoning: Be light on the salt in any rub you elect to use. The meat will have a residual salty flavor.
How Long will it take? Our roast was an 8-pound roast and took four hours. A 4-pound roast should take roughly 2 hours. But make sure you cook to temperature not time. 
Pastrami versus Corned Beef – Pastrami is very similar in that it is cured in a similar pickling liquid. The biggest difference is that pastrami has a specific spice rub of herbs and paprika and then steamed after being smoked.

  1. I’m going to make my first round for St. Paddy’s Day next week and appreciate your explanation of the difference between corned beef round vs brisket. Can you help me understand why the internal temperature is so drastically different between the two?

    1. Dana, a great question. For a brisket flat, we treat it like normal brisket in that we still need to break down the rather rough cut. So we go long on the cook. But the round we treat more like a roast or a steak, so we cook it to a lower temperature so it’s medium rare.

  2. 5 stars
    I smoked a corned beef today according to your recipe and it was delicious. I just wasn’t able to slice it as nice as you had in your photos 🙂 If I was to do it again I would probably soak it in water for a few hours to remove a little bit of the salt. Overall really good though.

  3. I have read that the pre-corned beef needs to be soaked in a few change`s of cold water to purge some of the salt before smoking.Has Sean tried both soaked and un soaked c/b in the smoker? I have not and would be interested in the results.

    1. Great point. So first I should share that we love salt. So we have done this straight from the packaging. And it was awesome.

      But, if you are someone more sensitive to salt, then it is absolutely appropriate for a soak in cold water. The cold water will pull salt out of the meat. For a small brisket flat, a 2 hour soak is all you need. For a 10 pound round or full packer brisket, you’ll want three soaks at 2 – 3 hours for each soak.
