If you have ever stared at a “city ham” in the grocery store—those pre-cooked, spiral-cut, or whole hams wrapped in plastic—and wondered if it could ever taste like something from a high-end BBQ joint, the answer is a resounding yes. Learning how to smoke a smoked ham, often referred to as a “double-smoked ham,” is the secret weapon of backyard chefs everywhere.
By putting a pre-cured, pre-cooked ham back onto a smoker, you aren’t just heating it up; you are layering flavors, rendering fat, and creating a caramelized crust that a standard oven simply cannot replicate. This guide will take you through every nuance of the process, from selecting the right wood to the final glaze.
Why Double-Smoke a Ham?
Most hams purchased at the supermarket are already smoked and fully cooked. However, this commercial smoking process is often done in large industrial ovens with liquid smoke or brief exposure to wood chips. When you take the time to smoke it a second time at home, you achieve several things:
- Depth of Flavor: The low and slow exposure to real wood smoke penetrates the outer layers of the meat, providing a more authentic BBQ profile.
- Texture Improvement: The gentle heat allows the internal fats to break down further, resulting in a more tender, juicy bite compared to the often-rubbery texture of a ham heated quickly in a kitchen oven.
- The Glaze Factor: A smoker provides the perfect environment for a sugar-based glaze to tack up and caramelize without burning, creating that sought-after “bark.”
Selecting Your Ham
Before you fire up the grill, you need the right canvas. Since we are focusing on how to smoke a smoked ham, you are looking for a “Ready-to-Eat” or “Fully Cooked” ham.
Spiral Cut vs. Whole Ham
Spiral-cut hams are convenient because they are already sliced to the bone. However, they are prone to drying out during a second smoke session because the smoke and heat can get between every slice. If you choose a spiral ham, you must be more aggressive with your basting. A whole (non-sliced) bone-in ham is generally preferred by enthusiasts because it retains moisture much better.
Bone-In vs. Boneless
Always go for bone-in if you have the choice. The bone acts as a heat conductor, helping the ham cook more evenly from the inside out, and it adds a significant amount of flavor. Plus, you get a ham bone for soup the next day.
Preparing the Ham for the Smoker
You shouldn’t take the ham directly from the plastic wrap to the smoker. A little preparation goes a long way.
The Scoring Process
If you have a whole ham, use a sharp knife to score the fat cap. Create a diamond pattern by cutting lines about 1 inch apart and 1/4 inch deep. This doesn’t just look professional; it allows the rendered fat to escape, the smoke to penetrate deeper, and the glaze to find “channels” to stick to.
The Binder and Rub
Even though the ham is salty, a rub adds complexity. Apply a light binder like Dijon mustard or maple syrup to the surface. Then, apply a dry rub. Since ham is naturally salty, look for a rub that is heavier on brown sugar, paprika, and warm spices like cloves or cinnamon, and lighter on the salt.
Setting Up Your Smoker
Whether you are using a pellet grill, an offset smoker, or a ceramic egg, consistency is the goal.
Choosing the Right Wood
Ham is a delicate meat that can easily be overwhelmed by heavy smokes like mesquite. Stick to fruitwoods or milder hardwoods.
- Apple: The gold standard for pork. It provides a sweet, mellow flavor.
- Cherry: Adds a beautiful mahogany color to the ham.
- Hickory: Use sparingly; it provides a classic “bacon-like” aroma but can be intense if used for the entire duration.
- Maple: Excellent for hams that will be finished with a maple or honey glaze.
Managing the Temperature
Target a smoker temperature of 225°F to 250°F. This range is high enough to render fat but low enough to prevent the lean meat from drying out. If you go much higher than 275°F, you risk toughening the exterior before the center is warm.
The Smoking Process
Once your smoker is stabilized at 225°F, place the ham on the grate. If you are using a bone-in ham, place it cut-side down. This protects the most exposed part of the meat from direct heat.
The Importance of Moisture
During the first two hours of smoking, you want to keep the environment humid. Place a water pan inside the smoker. Additionally, every 45 minutes, spritz the ham with a mixture of apple juice and apple cider vinegar. This prevents the surface from hardening into a “leathery” texture.
Internal Temperature Goals
Since the ham is already cooked, you aren’t “cooking” it to a safety temperature. You are heating it to a “palatability” temperature. You want the internal temperature to reach 140°F. This is the sweet spot where the meat is hot throughout but hasn’t begun to lose its structural integrity and moisture.
The Art of the Glaze
The glaze is the crowning achievement of a smoked ham. However, timing is everything. Because most glazes contain high amounts of sugar (honey, maple syrup, or brown sugar), they will burn if left over direct heat for too long.
When to Apply
Only apply your glaze during the last 30 to 45 minutes of the smoke. Wait until the ham reaches an internal temperature of about 130°F.
Crafting the Perfect Glaze
A great ham glaze needs a balance of sweet, acid, and spice. A classic combination includes:
- 1 cup Brown Sugar
- 1/4 cup Maple Syrup or Honey
- 2 tablespoons Apple Cider Vinegar
- 1 tablespoon Dijon Mustard
- A pinch of ground cloves or cinnamon
Simmer these ingredients in a saucepan until thickened, then brush it liberally over the ham. You can apply a second coat 15 minutes later for a thicker, tackier finish.
Resting and Serving
Once the ham hits 140°F, remove it from the smoker. This is the hardest part: let it rest. Tent the ham loosely with aluminum foil and let it sit for at least 20 to 30 minutes. This allows the juices to redistribute. If you cut into it immediately, the moisture will run out onto the cutting board, leaving you with dry meat.
When carving a bone-in ham, cut slices perpendicular to the bone. If you used a spiral-cut ham, simply run your knife around the center bone to release the pre-cut slices.
Common Mistakes to Avoid
- Overcooking: It is easy to think “more is better,” but taking a ham to 160°F or higher will turn it into sawdust. Trust your meat thermometer.
- Too Much Salt: Remember that the ham is already cured. Avoid using salty BBQ rubs. Focus on sweet and savory flavors.
- Skipping the Rest: Resting isn’t a suggestion; it is a mechanical necessity for juicy meat.
Frequently Asked Questions
How long does it take to smoke a pre-cooked ham?
Generally, you should plan for about 15 to 20 minutes per pound when smoking at 225°F. For a standard 8-pound ham, this usually translates to roughly 2.5 to 3 hours of total time on the smoker. Always rely on internal temperature rather than the clock.
Do I need to soak the ham before smoking?
Soaking is not necessary for standard “city hams” found in grocery stores. However, if you have purchased a “country ham,” which is dry-cured and extremely salty, you may need to soak it in water for 12 to 24 hours to leach out excess salt before you begin the smoking process.
Can I smoke a ham on a gas grill?
Yes, you can. To do this, use a two-zone setup where you turn on the burners on one side and place the ham on the unlit side. Use a smoker box or a foil pouch filled with wood chips over the active burners to create the necessary smoke. Maintain the grill’s ambient temperature at 250°F.
Should I wrap the ham in foil while smoking?
You do not need to wrap the ham initially, as you want the smoke to make contact with the meat. However, if you notice the edges of a spiral ham are starting to look dark or dry before the center is warm, you can “boat” the ham by placing it in a foil pan with a little liquid and covering the top loosely.
What are the best side dishes for smoked ham?
Smoked ham pairs perfectly with sides that offer a bit of acidity or creaminess to balance the salt and smoke. Classic choices include cheesy scalloped potatoes, honey-glazed carrots, vinegar-based coleslaw, or braised collard greens. For a brighter contrast, a fruit compote or pineapple chutney works beautifully.
