What is Corned Beef?

According to The Kitchn, Corned beef is made from brisket, a relatively inexpensive cut of beef. The meat goes through a curing process in a brine. It’s then slowly cooked, turning a tough cut of beef into one that’s super tender and flavorful.

If you’ve had corned beef before, you know how tasty it is, and you also know it’s fairly salty. The curing process is what adds all that salt to the meat. In addition to the salt, you can add some other really great flavors to the beef during the brining process.

How Do You Cure Corned Beef?

If you have the time to cure your own corned beef, I’d highly recommend it. It doesn’t take that long to cure a small brisket flat, and the flavor profile you get is totally worth it. The advantage to curing your own corned beef is that you know how long it has cured, and you don’t have to desalinize the meat before cooking.

Making the brine is simple, and we’re going to add a little kick to the flavor profile using Colman’s Mustard. This mustard is unlike anything I’ve ever tasted, and it’s damn good. The mustard is made with a blend of locally grown white and brown mustard seeds from Norwich, England.

Brine a Corned Beef Brisket in 24-Hours

For this recipe, we’re using a 2-pound piece of brisket flat that has the same thickness throughout. If your brisket is larger, you’ll want to adjust the time to make sure the brine has time to soak into the meat.

In a saucepan combine the following ingredients:

Stir the ingredients and then bring to a boil. Let the brine cool on the stove, and then chill in the refrigerator until you’re ready to corn the brisket.

Place the brisket flat in a large sealable plastic bag, and then pour the brine in. Get as much of the air out of the bag as possible, and then place the bag in the refrigerator for 24 hours. Flip the brisket in the bag after about 12 hours.

After 24 hours remove the brisket from the brine. Discard the excess brine and rinse off the brisket under cold water.

How to Desalinize a Brisket

If you decide to buy a corned beef brisket in the store or online instead of corning a brisket at home, you should let it soak in cold water for 4-6 hours to flush the excess salt out of the meat before smoking. I’ve skipped this step, and the end result is a salty nightmare that will have your guests drinking water by the gallons.

Smoked Corned Beef Brisket BBQ Rub

The Brisket is already going to have some excellent flavor, but this rub kicks it up a notch. It’s sweet, and the Colman’s Dry Mustard adds a little bit of kick to every bite.

In a small bowl combine the following ingredients:

  • 1 Tbsp Black Pepper
  • 2 Tbsp Paprika
  • 3 Tbsp Brown Sugar
  • 2 tsp Onion Powder
  • 2 tsp Garlic Powder
  • 1 Tbsp Colman’s Dry Mustard

Stir together with a fork and set aside.

How To Smoke Corned Beef

Before we smoke the corned beef brisket, we need to apply the rub. Spritz the brisket with apple juice, and then sprinkle some rub on all sides of the brisket.

Set up your smoker to smoke at 250 degrees and place the corned beef brisket directly on the grill grates.

Every 90 minutes spritz the brisket with apple juice to keep it moist. Continue letting it cook until the internal temperature hits 200 degrees.

When the smoked corned beef brisket is up to temp double wrap it with foil and let it rest for at least an hour in a high-quality cooler like a yeti.

What to Serve with Smoked Corned Beef?


The traditional side dish for corned beef is cabbage. I like to include some potatoes and chopped carrots too. Cut a head of cabbage into 8 wedges and place in a 9×12 baking dish. Add 6-8 red potatoes chopped into quarters, and a dozen carrots peeled and chopped into 3″ pieces.

In a small mixing bowl combine 6 ounces of beer (a stout works best) with 2 tablespoons of olive oil, 2 tablespoons of Colman’s Prepared Mustard, and 2 tablespoons of brown sugar.

Drizzle this sauce over the veggies, and then put in your oven to cook at 400 degrees. Rotate the veggies every 30 minutes until the potatoes are done (about 90 minutes total).

The brisket should be smoked until the internal temp hits 200 degrees. Use a good internal meat thermometer to check the temperature.
I estimate 90 minutes per pound for total cooking time.

  1. This is insanely good and I’m pretty sure the bast we have ever had. Rye bread, more mustard, even plates are all optional as we just ate it with our fingers as fast as I could slice it. I wouldn’t even begin to defile it with Swiss cheese, thousand island dressing or even our beloved homemade sauerkraut. Perfect as it is with nothing more than some good cold beer. Thanks for sharing 🙂

    1. Up to you. I use it to help season the veggies, but prefer to use my own low salt rub on the brisket if I’m buying one that’s already been corned at the store.

  2. I’ve read a lot of your recipes. What do you think about corned brisket with coffee in the rub.

  3. Made this recipe yesterday and absolutely loved it. The rub is amazing on corned beef. I followed the instructions to the t because it was the first time I had ever smoked a brisket. Ended up having the internal temp stall out at 160 degrees but stayed faithful to the recipe/instructions. After reaching what should have been the end time (estimated 90 minutes per pound), ended up placing the brisket into a foil pan, adding a beer, and covering it with foil. What should have been a 7.5 hour cook turned into 13 hours. However, I am not disappointed at all and everyone that has tried it asked if they could buy a brisket to throw in when I made this next time. This recipe is definitely a winner!

    1. Aaron Franklin describes your experience as the stall. Hard to get through 150 +/- deg. He recommends wrapping the brisket (corned beef) in foil or butcher paper until you see more accelerated temp. increase. Learned a lot from his book and video masterclass.

  4. Something is off on your weight, you say 2-3 pounds so 32-48 ounces of meat but then you say it yields 12, 5 ounce servings, so 60 ounces? We know meat shrinks when it smokes so how on earth were you able to “add” weight or is that just a typo?


  5. Made this last night and it was a big hit. Everyone commented on the flavor of the meat which is really brought out and complimented by this rub. I think the temperature of the meat is somewhat subjective. I cooked it to 198 in the center and it got pretty overdone on the flatter parts of the cut. I think it would be plenty cooked and a little juicier at 195. I had a 5 lb brisket and this was twice as much rub as needed.
