Cooking a ham on a Traeger pellet grill is one of the most effective ways to transform a standard holiday centerpiece into a smoky, succulent masterpiece. Unlike a traditional oven, a Traeger uses hardwood pellets to provide a consistent convective heat that infuses the meat with a depth of flavor that is impossible to replicate indoors.
However, the most common question for any backyard pitmaster remains: how long to cook a ham on a Traeger? Because most hams purchased at the grocery store are already precooked or “city hams,” the process is less about cooking from scratch and more about internal temperature management, moisture retention, and flavor development.
Understanding Your Ham Types
Before you set your Traeger to the desired temperature, you must identify the type of ham you are working with, as this significantly impacts your timing and preparation.
Most consumers purchase a fully cooked, bone-in or spiral-sliced ham. These are cured and often smoked by the manufacturer. Your goal on the Traeger is to reheat the ham to an internal temperature of 140°F without drying it out. If you have a “cook-before-eating” ham or a fresh, raw ham, the timeline changes drastically, as you must reach a safe internal temperature of 145°F and often allow for a much longer rendering period.
The weight of the ham is the primary variable. A standard 8 to 10-pound bone-in ham will generally take between 2.5 to 4 hours on a Traeger, depending on the ambient temperature and how often the lid is opened.
Preparing the Traeger and the Meat
To achieve the best results, start by preheating your Traeger to 250°F or 325°F. A lower temperature of 250°F is ideal if you want to maximize smoke penetration, especially if you are using a “Super Smoke” mode. A higher temperature of 325°F is better if you are short on time and want to focus more on the glazing process.
For wood pellet selection, fruitwoods like apple, cherry, or maple are the gold standard for pork. They provide a subtle sweetness that complements the salty brine of the ham. If you prefer a more robust, traditional BBQ profile, hickory is an excellent choice, though it can be overpowering if the ham is already heavily smoked.
Prepare your ham by removing it from the packaging and patting it dry. If it is not spiral-sliced, you can score the fat in a diamond pattern. This allows the smoke and glaze to penetrate deeper into the muscle. Place the ham in a disposable aluminum pan or a roasting pan; this catches the juices and makes the cleanup process much easier.
How Long to Cook a Ham on a Traeger: The Timeline
The general rule of thumb for reheating a precooked ham on a Traeger is 12 to 15 minutes per pound when smoking at 250°F. If you increase the heat to 325°F, that time drops to roughly 10 minutes per pound.
The First Two Hours: Smoke Infusion
During the First Two Hours of the cook, the focus is on smoke. Place the ham cut-side down in the pan. This protects the most surface area from drying out. You do not need to cover the ham with foil during this initial phase. The cool surface of the meat will attract the smoke particles, creating that sought-after mahogany color.
The Middle Phase: Moisture Management
Around the 2-hour mark, check the internal temperature using a reliable meat probe. You want to see the temperature rising steadily toward 100°F. At this point, many pitmasters choose to add a liquid to the bottom of the pan—such as apple juice, pineapple juice, or even a splash of bourbon—and cover the ham tightly with aluminum foil. This creates a braising environment that ensures the ham remains juicy.
The Final Hour: Glazing and Finishing
The glaze should be applied when the ham reaches an internal temperature of 130°F. If you apply a sugar-based glaze too early, the sugars will burn and turn bitter under the heat of the pellets.
Brush your glaze generously over the surface and between the slices if using a spiral-cut ham. Leave the foil off for the final 30 to 45 minutes of the cook. This allows the glaze to tack up and caramelize into a sticky, delicious crust. The ham is officially finished when the thickest part of the meat reaches 140°F for precooked varieties.
Factors That Influence Cooking Time
Ambient Temperature and Wind
Pellet grills are highly efficient, but they are still subject to the laws of thermodynamics. If you are smoking a Christmas ham in a blizzard, the Traeger will work harder to maintain 250°F, and every time you open the lid, you lose significant heat. Conversely, a hot summer day might accelerate the process.
Bone-In vs. Boneless
A bone-in ham usually takes longer to heat through because the bone acts as an insulator initially, though it eventually helps distribute heat once it gets warm. Boneless hams are denser and more uniform, which can sometimes lead to faster cooking times but a higher risk of drying out if not monitored closely.
Spiral Cut Considerations
Spiral-sliced hams are incredibly convenient, but they are prone to lose moisture quickly. Because the meat is already cut, there is more surface area for moisture to evaporate. If you are cooking a spiral ham, the “covered” portion of the cook is critical. You may even want to shorten the smoking time and increase the braising time to ensure the slices don’t become “ham jerky.”
Tips for the Best Traeger Ham
- Use a secondary thermometer. While the Traeger probe is helpful, a high-quality instant-read thermometer allows you to check multiple spots around the bone to ensure even heating.
- Resting is mandatory. Just like a brisket or a steak, ham needs to rest. Once you pull it off the grill, let it sit for at least 15 to 20 minutes. This allows the juices to redistribute so they stay in the meat rather than running out onto the cutting board.
- Don’t over-smoke. If you are using a fully cooked ham, it has already been smoked once. Adding 4 hours of heavy hickory smoke can make the flavor acrid. Stick to lighter woods and consider only using the “Super Smoke” setting for the first hour.
Frequently Asked Questions
What is the best internal temperature for a Traeger ham?
For a fully cooked or “city” ham, the target internal temperature is 140°F. This temperature ensures the meat is hot throughout while remaining moist. If you are cooking a fresh, raw ham, you must reach an internal temperature of 145°F followed by a three-minute rest for safety.
Should I cook the ham flat side down or on its side?
You should always start a ham with the flat, cut side facing down. This protects the interior meat from direct exposure to the heat and helps keep the moisture locked inside the structure of the ham. If you are glazing toward the end, you can carefully reposition it if needed, but flat side down is the safest bet for the majority of the cook.
Do I need to put water in the pan when smoking a ham?
While not strictly necessary, adding a liquid like apple juice, cider vinegar, or water to the roasting pan creates steam. This humidity helps the smoke adhere to the meat and prevents the exterior from becoming tough or leathery. It also provides the base for a delicious au jus or gravy later on.
How do I prevent a spiral ham from drying out on the Traeger?
The best way to protect a spiral ham is to wrap it tightly in heavy-duty aluminum foil once it reaches about 100°F internal temperature. Adding a bit of liquid inside the foil wrap creates a “steam-lock” that keeps the individual slices tender. Only uncover the ham for the final 20 minutes to set the glaze.
Can I cook a frozen ham on a Traeger?
It is not recommended to cook a ham from a frozen state. This leads to uneven cooking where the outside becomes overdone and dry before the center reaches a safe temperature. Always thaw your ham completely in the refrigerator for 24 to 48 hours before placing it on the pellet grill.
