Smoking a spiral ham on a pellet grill is one of the easiest ways to elevate a holiday centerpiece or a Sunday dinner. While most spiral hams come pre-cooked, the magic happens when you introduce wood-fired flavor and a sticky, caramelized glaze. By using a pellet grill, you gain precise temperature control that ensures the meat stays juicy while the exterior develops a beautiful mahogany crust.
Choosing the Right Spiral Ham
Before you even fire up the grill, the quality of your ham determines the final result. Most grocery store spiral hams are “city hams,” meaning they have been wet-cured and pre-smoked. This is actually an advantage for the backyard cook because you aren’t starting from raw pork; you are essentially performing a double-smoking process that intensifies the flavor.
Look for a ham that is labeled “bone-in.” The bone acts as a conductor of heat and adds significantly more flavor and moisture to the meat compared to boneless varieties. Additionally, check the packaging to ensure it hasn’t been pumped with an excessive amount of water and salt solution, which can lead to a rubbery texture once reheated.
Preparing Your Pellet Grill
The beauty of a pellet grill lies in its “set it and forget it” nature. For a double-smoked spiral ham, you want to aim for a low and slow approach. This allows the smoke to penetrate the slices without drying out the lean meat.
Selecting the Best Pellets
The type of wood you choose will dictate the flavor profile of the ham. Since pork is naturally sweet, fruitwoods are often the best choice.
- Apple: Provides a mild, sweet smoke that complements the natural sugars in the ham.
- Cherry: Offers a similar sweetness but adds a deep, reddish hue to the bark.
- Hickory: For those who prefer a more traditional, pungent smoke flavor.
- Pecan: A middle ground that offers a nutty, rich aroma without being overpowering.
Setting the Temperature
Preheat your pellet grill to 225°F. This lower temperature is crucial for spiral hams. Because the ham is already sliced, high heat will cause the edges to curl and dry out before the center reaches the desired temperature. By staying at 225°F, you allow the smoke to settle into every crevice of the spiral cuts.
Prepping the Ham for the Smoke
Because spiral hams are pre-sliced, they are susceptible to moisture loss. Your goal during prep is to protect the meat while adding layers of flavor.
Remove the ham from its packaging and pat it dry with paper towels. Many hams come with a glaze packet; feel free to discard this in favor of a homemade version that packs more punch. If you want to add a dry rub, apply a thin layer of mustard as a binder, then sprinkle a sweet-leaning BBQ rub over the surface. Look for rubs containing brown sugar, paprika, and a hint of clove or cinnamon to lean into those traditional ham flavors.
To keep the ham moist, place it cut-side down in a shallow disposable aluminum pan. This prevents the juices from running off into the grill and allows you to add a braising liquid. Pouring a cup of apple juice, pineapple juice, or even a spiced ginger ale into the bottom of the pan creates a flavorful steam environment.
The Smoking Process
Once your grill is holding steady at 225°F, place the pan with the ham directly on the grill grates.
Monitoring the Internal Temperature
You are not cooking the ham to a “done” temperature in the traditional sense, as it is already cooked. Instead, you are warming it through. The target internal temperature for a perfectly warmed spiral ham is 140°F. Using a wireless meat thermometer is the best way to track this without constantly opening the grill lid and losing heat.
Spritzing for Moisture
Every 45 minutes, consider spritzing the ham with a mixture of apple juice and apple cider vinegar. This keeps the exterior from getting “leathery” and helps the smoke particles adhere to the meat.
Crafting the Perfect Glaze
The glaze is the “wow” factor of a smoked spiral ham. You want something that balances sweetness, acidity, and a little bit of heat. A classic combination includes brown sugar, honey or maple syrup, Dijon mustard, and a splash of bourbon or apple cider vinegar.
In a small saucepan over medium heat, whisk your ingredients together until the sugar is completely dissolved and the mixture has thickened slightly. Do not apply the glaze at the beginning of the cook. Because of the high sugar content, a glaze will burn if exposed to heat for too long.
When to Apply the Glaze
Wait until the ham reaches an internal temperature of 130°F. At this point, generously brush the glaze over the entire ham, making sure to let it drip down into the spiral slices. Increase the grill temperature to 350°F for the final 10 to 15 minutes of the cook. This higher heat “sets” the glaze, turning it into a sticky, tacky coating that clings to the meat.
Resting and Serving
Once the ham hits 140°F, remove it from the grill. This is a critical step: let the ham rest in the pan, loosely covered with foil, for at least 15 to 20 minutes. Resting allows the juices to redistribute through the fibers. If you cut into it immediately, all that moisture you worked so hard to preserve will end up at the bottom of the pan.
Since the ham is already spiral-cut, serving is simple. Run a knife around the center bone to release the slices. They should fall away effortlessly, ready to be plated with a spoonful of the juices from the pan.
Tips for Success
If you find that the top of the ham is browning too quickly, you can create a “foil hat” to shield it. Simply place a piece of aluminum foil loosely over the top point of the ham while leaving the sides exposed to the smoke.
Also, don’t throw away the ham bone! The smoky flavor infused by the pellet grill makes the bone a goldmine for future meals. Use it to flavor a pot of split pea soup, navy bean stew, or collard greens.
Frequently Asked Questions
How long does it take to smoke a spiral ham at 225°F?
Generally, you should plan for about 12 to 15 minutes per pound. For an average 8 to 10-pound ham, the process typically takes between 2 and 3 hours. However, always cook to internal temperature rather than time, as variables like wind and ambient temperature can affect the grill.
Can I smoke a ham that is still frozen?
It is highly recommended to fully thaw your ham in the refrigerator before smoking. Smoking a frozen ham leads to uneven cooking, where the outside becomes dry and overcooked while the center remains cold. Allow 24 hours of thawing time for every 5 pounds of meat.
Do I need to wrap the ham in foil?
Wrapping is not strictly necessary if you use a pan and a braising liquid. However, if you notice the ham is reaching your target temperature too slowly or the edges are looking too dark, you can tightly wrap the entire pan in foil to speed up the process and lock in moisture.
What is the best way to store and reheat leftovers?
Store leftover smoked ham in an airtight container in the refrigerator for up to 4 days. To reheat, place slices in a baking dish with a splash of water or broth, cover tightly with foil, and warm in an oven at 325°F until heated through. This prevents the meat from drying out during the second round of heating.
Why is my spiral ham dry after smoking?
Dryness is usually caused by two things: cooking at too high a temperature or leaving the ham on the grill for too long. Because spiral hams are pre-sliced, they have more surface area for moisture to escape. Ensure you stay at 225°F and pull the ham exactly when it hits 140°F internal temperature.
