When most people think of a holiday ham, they picture a crowded kitchen, a steaming oven, and a frantic cook checking the timer every ten minutes. However, there is a better way to achieve a smoky, succulent, and perfectly glazed centerpiece without ever turning on your oven. Learning how to cook a ham on a grill is a game-changer for backyard chefs and holiday hosts alike. By moving the process outdoors, you free up valuable kitchen space and infuse the meat with a subtle, smoky depth that a conventional oven simply cannot replicate.
Whether you are using a gas grill for convenience or a charcoal grill for that classic wood-fired flavor, grilling a ham is surprisingly straightforward. Since most hams purchased at the grocery store are already precooked or “city hams,” your job isn’t so much about cooking the meat from scratch as it is about gently reheating it while adding layers of flavor through wood smoke and sweet, sticky glazes.
Choosing the Right Ham for Your Grill
Before you fire up the burners, you need to select the right cut of meat. Not all hams are created equal, and the type you choose will dictate your grilling strategy.
Bone-In vs. Boneless
A bone-in ham is generally the preferred choice for grilling. The bone acts as a conductor of heat, helping the interior warm up more evenly, and it provides significantly better flavor and moisture. Boneless hams are easier to slice, but they can dry out more quickly under the dry heat of a grill. If you want that “wow” factor for a dinner party, go with a shank-end or butt-end bone-in ham.
Spiral-Cut vs. Whole
Spiral-cut hams are incredibly popular because they come pre-sliced, making serving a breeze. However, because the meat is already cut, it is much more prone to drying out on the grill. If you choose a spiral-cut ham, you must be extra vigilant about your moisture levels. A whole, uncut ham is more forgiving and allows you to score the fat yourself, creating those beautiful diamond patterns that hold onto glazes so effectively.
Smoked and Cured Hams
Most hams found in the refrigerated aisle are already cured and smoked. This means they are technically ready to eat. Your goal on the grill is to bring the internal temperature up to 140 degrees Fahrenheit. If you happen to buy a “fresh” ham (one that hasn’t been cured or smoked), the process is entirely different and requires much longer cooking times to reach a safe 160 degrees Fahrenheit.
Setting Up Your Grill for Success
The secret to a great grilled ham is indirect heat. You never want to place a large ham directly over a flame, as the high sugar content in the meat and any potential glaze will burn long before the center is warm.
Gas Grill Setup
If you are using a gas grill, turn on one side of the burners to medium-high and leave the other side off. This creates a hot zone and a cool zone. You will place the ham on the cool side. Place a disposable foil pan filled with an inch of water or apple juice directly under the grates on the cooler side to add moisture and catch drippings.
Charcoal Grill Setup
For charcoal enthusiasts, pile your lit briquettes or lump charcoal on one side of the grill. You can also place them in two piles on opposite sides, leaving a gap in the middle. This “two-zone” lighting method ensures the ham receives gentle, ambient heat. Adding a few chunks of apple, cherry, or hickory wood to the coals will enhance the smoky profile of the meat.
The Step-by-Step Grilling Process
Once your grill is stabilized at a steady 325 degrees Fahrenheit, it is time to prep the meat.
Prepping the Ham
Take the ham out of the refrigerator about 30 to 60 minutes before grilling to take the chill off. If the ham is not spiral-cut, use a sharp knife to score the surface in a diamond pattern, cutting about a quarter-inch deep. This allows the fat to render and provides “pockets” for your glaze to settle into. You can also press whole cloves into the intersections of the diamonds for a classic aesthetic and aromatic boost.
Wrapping for Moisture
To prevent the exterior from becoming tough or “leathery,” many experts recommend wrapping the ham in heavy-duty aluminum foil for the first half of the cooking process. You can pour a half-cup of pineapple juice or apple cider into the foil pouch before sealing it. This creates a steaming environment that keeps the meat incredibly tender.
Monitoring the Temperature
Place the ham on the grill, cut-side down if it is a half-ham, and close the lid. You are looking for a grill temperature maintained between 300 degrees Fahrenheit and 325 degrees Fahrenheit. A general rule of thumb is to grill the ham for about 12 to 15 minutes per pound. Use a reliable meat thermometer to check the internal temperature periodically, inserting it into the thickest part of the meat without hitting the bone.
Crafting the Perfect Glaze
The glaze is where you can truly show off your culinary personality. While you can use the packet that often comes with the ham, a homemade glaze is infinitely better.
Sweet and Savory Bases
Most glazes start with a sugar base to encourage caramelization. Brown sugar, honey, maple syrup, or apricot preserves are excellent choices. To balance the sweetness, add acidity and spice. Common additions include:
- Dijon or yellow mustard for a tangy bite.
- Apple cider vinegar or pineapple juice for brightness.
- Bourbon or dark rum for a sophisticated, smoky depth.
- Spices like cinnamon, cloves, nutmeg, or even a pinch of cayenne pepper for heat.
When to Apply the Glaze
Timing is everything. Because glazes are high in sugar, they will burn if left on the grill for too long. Wait until the ham reaches an internal temperature of 130 degrees Fahrenheit. Remove the foil (if used), brush a thick layer of glaze all over the ham, and continue grilling uncovered. Apply a fresh layer of glaze every 10 to 15 minutes until the internal temperature reaches the target of 140 degrees Fahrenheit. This builds a beautiful, tacky, and caramelized crust.
Resting and Serving
Once the ham hits 140 degrees Fahrenheit, remove it from the grill immediately. This is a crucial step that many beginners skip.
The Importance of Resting
Transfer the ham to a carving board or a warm platter and tent it loosely with foil. Let it rest for at least 15 to 20 minutes. During this time, the juices that were pushed toward the center by the heat will redistribute throughout the meat. If you carve it immediately, those juices will run out onto the board, leaving you with dry meat.
Carving Techniques
For a bone-in ham, cut slices vertically toward the bone, then make a horizontal cut along the bone to release the slices. If you have a spiral-cut ham, simply cut around the center bone to free the pre-sliced pieces. Serve your grilled ham with the remaining glaze on the side or a dollop of honey-mustard sauce.
Frequently Asked Questions
-
How long does it take to grill a 10-pound ham?
On average, a 10-pound precooked ham will take between 2 and 2.5 hours to reach the proper internal temperature when grilled at 325 degrees Fahrenheit. Always rely on a meat thermometer rather than the clock, as grill temperatures can fluctuate based on the weather and air vent adjustments. -
Do I need to soak wood chips before adding them to the grill?
While some old-school recipes suggest soaking wood chips, many modern pitmasters prefer dry wood. Dry wood produces a clean, thin blue smoke that flavors the meat without making it bitter. If you use wood chunks instead of chips, they will smolder longer and provide a more consistent smoke profile for the duration of the cook. -
Can I cook a frozen ham on the grill?
It is not recommended to cook a frozen ham directly on the grill. The exterior will likely burn or dry out before the center reaches a safe temperature. For the best results, thaw your ham completely in the refrigerator for 24 to 48 hours before you plan to grill it. -
What is the best wood flavor for grilling ham?
Fruitwoods like apple, cherry, and peach are the most popular choices for ham because their natural sweetness complements the pork perfectly. Hickory is also a great choice if you prefer a more traditional, robust bacon-like smoke flavor. Avoid heavy woods like mesquite, which can easily overpower the delicate flavor of the ham. -
What should I do with the leftover ham bone?
Never throw away the bone! A grilled ham bone is packed with smoky flavor and is the perfect base for soups, stews, or a pot of slow-cooked beans. You can wrap the bone in plastic wrap and freeze it for up to three months until you are ready to make a hearty split pea soup or red beans and rice.
