When you think about smoked ham, you might picture a traditional holiday centerpiece or a rustic backyard BBQ feast. But here’s the thing: most hams you find in grocery stores are already pre-cooked. That might lead to some confusion. If it’s pre-cooked, why smoke it again?
The answer is simple smoking a pre-cooked ham isn’t about cooking it through. Instead, it’s about infusing it with rich, smoky flavor, adding a glossy glaze, and reheating it gently until it’s tender, juicy, and ready to serve. This is often referred to as making a “double-smoked ham,” and it’s a favorite technique among pitmasters and home cooks alike.
But how long does it actually take to smoke a pre-cooked ham? The short answer is: 10–15 minutes per pound at 225–250°F until the ham reaches an internal temperature of 140°F. The long answer involves preparation, glaze timing, smoker setup, and a few tricks to keep the ham from drying out.
This comprehensive guide will walk you through everything you need to know about smoking a pre-cooked ham from choosing the right cut to adding flavorful glazes, plus all the timing details you need for success.
Choosing the Right Pre-Cooked Ham
Before you fire up your smoker, you’ll need to pick the right ham. Pre-cooked hams come in several forms, and the type you choose can affect your cooking time and final results.
Types of Pre-Cooked Ham
- Whole Ham – The full leg, typically weighing 15–20 pounds. Perfect for a large gathering but takes longer to smoke.
- Half Ham – Either the shank (lower portion, leaner) or butt (upper portion, meatier). These weigh 6–10 pounds and are easier to handle.
- Spiral-Cut Ham – Pre-sliced around the bone for easy serving. Very popular for holidays. Needs careful smoking to avoid drying out.
- Boneless Ham – Convenient and uniform in shape. Smokes more quickly but may not have as much flavor as bone-in.
Bone-In vs. Boneless
- Bone-in hams usually retain more flavor and moisture, and the bone helps conduct heat evenly.
- Boneless hams are easier to slice but may dry out faster.
For smoking, spiral-cut bone-in half hams are the most common choice they balance flavor, size, and convenience.
Preparing the Ham Before Smoking
Since your ham is already cooked, preparation is about enhancing flavor and presentation.
Step 1: Remove Packaging
Discard any plastic wrap, netting, or glaze packets that often come with store-bought hams.
Step 2: Pat Dry and Trim
Use paper towels to dry the ham. Trim away excess fat, but leave a thin layer—fat renders and adds moisture during smoking.
Step 3: Score the Ham
Scoring means cutting shallow crisscross lines into the surface of the ham. This helps glazes seep in and gives the ham that classic diamond pattern.
Step 4: Optional Brine or Injection
Though pre-cooked hams don’t need brining, you can boost moisture and flavor by injecting fruit juice or broth. A popular injection blend includes apple cider, pineapple juice, brown sugar, and a pinch of cloves.
Recommended Smoking Temperatures
Smoking isn’t about blasting heat—it’s about slow, gentle cooking.
- Ideal Smoking Temperature: 225–250°F
- Why Low and Slow? The ham is already cooked. The goal is to reheat without drying it out, while allowing time for smoke to flavor the meat.
Best Wood Choices
The wood you choose shapes the final flavor:
- Hickory: Strong, classic BBQ flavor.
- Applewood: Sweet, fruity smoke—pairs beautifully with ham.
- Cherry: Adds a subtle fruitiness and a gorgeous red hue.
- Pecan: Mild, nutty flavor for a balanced smoke.
How Long to Smoke a Pre-Cooked Ham
Here’s the part you came for—timing.
General Rule of Thumb
10–15 minutes per pound at 225–250°F
Example Cooking Times
- 8–10 lb ham: 2–2.5 hours
- 12–14 lb ham: 3–4 hours
- Whole 18–20 lb ham: 4.5–6 hours
Remember: these times are guides. The only reliable way to know when your ham is ready is by checking its internal temperature.
Target Internal Temperature
Since the ham is pre-cooked, your goal is to bring it to 140°F in the thickest part. That’s hot enough to be safe and juicy but not so hot that it dries out.
Adding Flavor with Glaze
The glaze is what transforms a simple smoked ham into a showstopper. It caramelizes, adds shine, and infuses the ham with sweet or savory notes.
When to Apply Glaze
- Brush glaze on during the last 30 minutes of smoking.
- Too early and it may burn or dry out.
Popular Glazes
- Classic Brown Sugar & Mustard
- 1 cup brown sugar
- ¼ cup Dijon mustard
- 2 tbsp apple cider vinegar
- Maple-Bourbon Glaze
- ½ cup pure maple syrup
- 2 tbsp bourbon
- 2 tbsp butter
- Dash of cayenne pepper
- Pineapple & Honey Glaze
- ½ cup pineapple juice
- ¼ cup honey
- 2 tbsp soy sauce
- 1 tsp ground ginger
For maximum flavor, apply two to three coats of glaze, allowing each layer to set before adding the next.
Checking Doneness
Doneness is about temperature, not time.
- Insert a meat thermometer into the thickest part of the ham (not touching bone).
- When it reads 140°F, your ham is ready.
For spiral-cut hams, check between the slices to ensure the inside has heated through without overcooking the edges.
Resting and Serving
Once the ham hits 140°F, remove it from the smoker. Tent it loosely with foil and let it rest for 10–15 minutes. This rest period allows juices to redistribute.
Serving Suggestions
- Slice thin for sandwiches or holiday platters.
- Pair with sides like scalloped potatoes, green beans, cornbread, or mac and cheese.
- Use leftovers for soups, casseroles, or breakfast omelets.
Tips for Best Results
- Keep it Moist: Place a drip pan with water, apple juice, or cider under the ham to create steam.
- Cover Spiral Hams: Wrap in foil for part of the cooking process to prevent drying.
- Baste Often: Every 30–45 minutes, brush on glaze or mop with fruit juice.
- Add Smoke Early: Most smoke flavor is absorbed in the first 2 hours—make those count.
Common Mistakes to Avoid
- Smoking Too Hot – Higher temps can dry out ham. Stick to 225–250°F.
- Skipping the Thermometer – Never guess doneness. A thermometer is essential.
- Glazing Too Early – Sugary glazes burn easily. Wait until the last 30 minutes.
- Not Resting the Ham – Cutting too soon lets juices escape. Always rest before slicing.
Variations
Smoking a pre-cooked ham is versatile. Try these ideas:
- Double-Smoked Ham – The most popular variation: re-smoking a pre-smoked ham for deeper flavor.
- Savory Ham – Skip the sweet glaze and rub with garlic, rosemary, and olive oil.
- Grill Method – If you don’t have a smoker, set up your gas or charcoal grill for indirect heat and add wood chips.
Conclusion
Smoking a pre-cooked ham is less about cooking and more about transforming a store-bought staple into something extraordinary. By smoking it low and slow at 225–250°F for about 10–15 minutes per pound, you’ll reheat it gently, infuse it with smoky depth, and bring it to that perfect 140°F internal temperature.
Add a glaze in the final stretch, let it rest, and you’ve got a centerpiece worthy of any feast juicy, smoky, and full of character.
So next time you’re planning a holiday dinner, Sunday family meal, or backyard BBQ, don’t just bake that pre-cooked ham. Smoke it. With the right timing, temperature, and glaze, you’ll turn an ordinary ham into an unforgettable dish.
