You Need To Try Smoking Corned Beef Brisket

Using a smoker gives corned beef a rich, smoky flavor and an incredible texture you just can’t get from boiling. It does take a few hours, so plan ahead, but the payoff is a tender, flavorful brisket that’s completely worth it. Once you try smoked corned beef, you may never want to make it any other way.

What is Smoked Corned Beef?

Smoked corned beef combines two cooking techniques: smoking and corned beef. Corned beef is a beef brisket that has been cured in a seasoned brine, typically made from salt, sugar, and various spices like peppercorns, mustard seeds, bay leaves and more. The curing process takes several days to a week, and it helps to tenderize the meat and infuse it with amazing flavor. Luckily for us, store-bought corned beef is readily available this time of year and can be a great shortcut.

Ingredient Notes for Smoked Corned Beef Brisket

It goes without saying that to smoke a brisket, you’ll need a smoker. Here are a few simple ingredients that help create all that classic corned beef flavor.

• Corned Beef Brisket – I used a 3-pound store-bought corned beef brisket, but any size that comfortably fits in your smoker will work.
• Pickling Spices – Whether you use the seasoning packet that comes with the brisket or make your own blend, these spices give corned beef its signature flavor.
• Beef Stock – Adds extra moisture while smoking and helps keep the brisket juicy and tender throughout the long cook.

If using the dry rub:

• Cinnamon Stick – Adds a little warmth and depth to the spice mix.
• Bay Leaf – Brings a mild herbal flavor that works well with the beef.
• Black Peppercorns – Add a classic peppery flavor to the brisket.
• Mustard Seeds – Give the seasoning blend a slightly tangy flavor.
• Cardamom Pods – Add a light, warm flavor that complements the other spices.
• Coriander Seeds – Bring a mild citrusy note to the spice blend.
• Juniper Berries – Add a subtle earthy flavor that pairs well with corned beef.
• Allspice Berries – Contribute a warm, slightly sweet spice flavor.
• Cloves – Add a rich flavor that’s commonly found in corned beef seasonings.
• Chiles de Arbol (or red pepper flakes)– Add a little heat, or use red pepper flakes if that’s what you have on hand.

If you don’t have one or two of these spices on hand, that doesn’t mean you can’t still make this recipe. The flavor may differ a bit from mine, but you will still have a delicious corned beef because it’s likely already been brined in most of these spices.

Feel free to experiment with different spice combinations to customize the flavor of your brisket.

Note: Just a heads up, this rub has a bit of heat to it, so if you’re sensitive to spice, you can leave it out or just use half.

How to Make Smoke Corned Beef Brisket

Low and slow is the name of the game here, but it’s so worth the wait. For full recipe details, including ingredient measurements, see the printable recipe card below. I’ve included instructions if you want to make a homemade rub, but you can also skip that step and place the corned beef right on the smoker. Here are step-by-step instructions for smoking a corned beef brisket:

Step 1: Preheat Smoker + Remove Corned Beef From Brine

Preheat your smoker to 250° F. Since every smoker is different, you’ll want to follow the manufacturer instructions for startup. I use a Traeger Wood Fired Pellet Grill. Remove corned beef from brine or packaging, rinse with cold water, and pat dry with paper towels. 

Pro Tip: My favorite wood pellets (or wood chips) to use for corned beef is Cherry or Apple, but any kind of fruit wood works well here. Honestly, whatever you have on hand will be fine. Beef is cool like that.

Step 2: If Using a Rub, Toast Spices and Grind

Place all Corned Beef Spice ingredients in small dry skillet and toast over medium heat, shaking pan occasionally being careful not to burn (do not walk away!). This should only take 2-3 minutes.

Transfer half of the spices to a spice grinder to achieve semi-fine powder for the rub. Alternatively, you can use a mortar and pestle if you prefer a rough grind. Reserve the other half of the whole spices for later on when you place brisket in liquid (see step #4).

Step 3: Place Corned Beef in Preheated Smoker

Place corned beef directly on the smoker grate, fat side up and insert your smoker’s meat thermometer probe into the thickest part of the brisket. Smoke for 3-4 hours or until the meat reaches an internal temperature of 165° F. 

Step 4: Combine Broth + Pickling Spices

Once your meat reaches 165° F, mix beef broth and pickling spices (either the other half of your homemade blend from above or the packet that comes with your beef) in an aluminum pan. Take the corned beef off the smoker grate and place in the aluminum pan. Reinsert your smoker’s meat thermometer probe into the thickest part of the brisket. Cover tightly with aluminum foil. 

Step 5: Return Beef to the Smoker

Smoke for another 3-4 hours until the meat reaches an internal temperature of 203° F. 

Step 6. Let Meat Rest, Then Slice + Serve

Remove from smoker and let rest for 30 minutes. Thinly slice corned beef against the grain with a sharp knife and serve warm.

How Long To Smoke Corned Beef

Smoking time will depend on the size of your corned beef, but you should expect to smoke it for about 6-8 hours total. The first 3-4 hours will be uncovered, directly on the grill grates, followed by another 3-4 hours covered in a pan of liquid, like broth. Corned beef is done when it reaches an internal temperature of 203° F. 

What temperature for Smoking a Corned Beef Brisket?

Corned Beef is very forgiving with temperature but I have found that setting your smoker to 250° F is the sweet spot.

Tools You’ll Need

A few simple tools will help you make perfectly smoked corned beef brisket. These are the items I used to get great flavor and consistent results.

• Pellet smoker – I used a pellet smoker for this recipe because it maintains a steady temperature with minimal effort while adding great smoky flavor to the corned beef brisket.
• Meat thermometer – The best way to know when your brisket is perfectly tender. A meat thermometer takes the guesswork out of cooking and helps prevent overcooking.
• Aluminum pan – Useful for catching drippings and helping retain moisture during the smoking process. It also makes cleanup much easier.
• Measuring cups and spoons – If you’re making the optional spice rub, measuring cups and spoons help ensure the seasoning blend is balanced and flavorful.
• Mortar and pestle or spice grinder – Great for crushing whole spices for a fresher, more aromatic rub.

Tips for Success

A few simple tips can help you get the best results from your smoked corned beef brisket. Keep these in mind for a tender, flavorful finished brisket every time.

• Slice Against the Grain – For the most tender bites, always slice the brisket against the grain. This shortens the muscle fibers and makes each slice easier to chew.
• Plan for Extra Time – Every brisket cooks a little differently, so give yourself some wiggle room. It’s better for the meat to finish early and rest than to rush the process.
• Don’t Skip the Resting Time – Resting allows the juices to redistribute throughout the meat. Cutting into it too soon can cause those flavorful juices to run out.
• Save the Leftovers – Smoked corned beef makes fantastic sandwiches, hash, and Reuben-style leftovers the next day. Store any extras in the refrigerator with a little of the cooking juices to help keep the meat moist.
• Use a Sharp Knife – A sharp slicing knife makes it much easier to cut clean, even slices without shredding the brisket.

Storing and Reheating Smoked Corned Beef Brisket

If you plan to use the corned beef for sandwiches or quick snacks, slicing it before storing makes it much easier to portion and reheat as needed.

To store in the fridge:
Let the brisket cool to room temperature, then transfer it to an airtight container. It will keep well in the refrigerator for about 4–5 days.

To freeze:
For longer storage, place the cooled corned beef in an airtight container or freezer bag, removing as much air as possible. It will keep in the freezer for up to 2–3 months.

To reheat:
For best results, reheat slices gently so they stay tender and juicy. Warm them in a skillet over low heat with a splash of broth or water, or cover and heat in the oven at a low temperature until just warmed through. You can also microwave in short intervals, covered with a damp paper towel to help retain moisture.

FAQs

Variations

Here are some variations you can try if you want to change up the flavor a bit.

• Classic Spice Boost – If you’re missing a spice or two, don’t worry. The corned beef is already well-seasoned from the brine, so small changes will still give you great flavor.
• Pepper-Forward Brisket – Add extra cracked black pepper to the rub for a bolder, more traditional pastrami-style bite that stands out against the smoke.
• Sweet & Smoky Version – Mix in a touch of brown sugar or maple powder for a subtle sweetness that balances the savory, salty beef.
• Garlic & Herb Twist – Add dried herbs like thyme, rosemary, or oregano to the seasoning for a more aromatic, herb-forward flavor profile.
