Spiral hams are a staple for many holiday meals and special occasions. Their pre-sliced design makes them convenient and easy to serve, but knowing how long it takes to properly reheat and prepare them is essential for both food safety and flavor. In this comprehensive guide, we’ll walk you through everything you need to know about cooking a fully cooked spiral ham—including preparation steps, oven times, glazing tips, and common pitfalls to avoid.
Whether you’re preparing for a family holiday dinner or a Sunday feast, this article will help you ensure your ham is perfectly warmed, juicy, and bursting with flavor.
Understanding Ready-to-Eat Spiral Hams
Spiral hams are fully cooked hams that have been pre-sliced in a spiral pattern around the bone, making them easy to serve in uniform portions. Most spiraled hams are cured and smoked, and they’re typically sold fully cooked in grocery stores and butcher shops.
Because they come already cooked, the main objective when preparing them at home is to warm them through without drying them out. Overcooking a spiral ham can lead to a dry, tough texture and diminished flavor, so it’s important to understand the cooking process and timing.
Why Spiral Hams Need Reheating
Even though spiral hams are fully cooked, they are often refrigerated or frozen after packaging. Reheating ensures that the ham reaches a safe eating temperature while also enhancing the flavor through techniques like glazing and caramelization.
Key Factors That Affect Cooking Time
Several variables influence the amount of time it takes to reheat a spiral ham:
- Ham weight: Larger hams naturally require more time to warm through.
- Oven temperature: The general recommended range is 275°F to 325°F (135°C to 163°C).
- Starting temperature of the ham: A ham that has been brought to room temperature before heating may cook more evenly.
- Glazing method and timing: Applying a glaze during the final portion of heating adds flavor and complexity to the final product.
Recommended Reheating Times for Fully Cooked Spiral Hams
The golden rule for reheating a spiral ham is to allow 10 to 15 minutes per pound at a temperature of 275°F to 325°F (135°C to 163°C). This interval allows the meat to warm thoroughly without overcooking or toughening.
Estimated Reheating Times by Weight
To better understand how long you need to plan for cooking your spiral ham, here’s a detailed breakdown:
| Ham Weight | Reheating Time (275°F) | Reheating Time (325°F) | Final Internal Temperature |
|---|---|---|---|
| 5 – 7 lbs | 80 – 100 mins | 60 – 80 mins | 135°F – 145°F |
| 8 – 10 lbs | 120 – 150 mins | 90 – 120 mins | 135°F – 145°F |
| 11 – 15 lbs | 160 – 220 mins | 120 – 160 mins | 135°F – 145°F |
Note: Keep a meat thermometer handy. The ham is ready when the internal temperature reaches 135°F to 145°F (57°C to 63°C); further heating after removing from the oven will help it rise slightly.
Calculating Cooking Time at Home
Let’s say you have a 10-pound spiral ham and decide to reheat it at 325°F. Based on the recommended guidelines, this would take approximately 10 minutes per pound, or about 100 minutes total. However, oven temperatures can vary, so it’s wise to start checking the internal temperature after 90 minutes.
Using a digital meat thermometer, insert it into the thickest part of the ham—be sure not to touch the bone. If it reads below 135°F, continue reheating in 10-minute increments until it hits the desired range.
Preparing Your Spiral Ham for the Oven
Proper preparation is crucial to ensure your ham stays moist and flavorful during reheating.
Unpack, Rinse, and Pat Dry
Remove the spiral ham from its packaging, and if your ham has a thick coating of gelatin or excess brine, rinse it lightly under cool water. Then pat it dry thoroughly with paper towels to prevent excess moisture on the surface, allowing for better caramelization and glazing.
Apply a Flavorful Glaze
While it’s not required, applying a glaze during the last 20 to 30 minutes of reheating can dramatically enhance both the flavor and presentation of your spiral ham.
Here’s a classic glazing option to try:
Simple Brown Sugar Glaze:
Mix all ingredients and brush generously over the ham when it has about 25 minutes of reheating left.
Other optional glazes include:
Wrap in Foil or Use a Ham Bag
To prevent the ham from drying out, it’s best to wrap it in aluminum foil or place it in a dedicated oven-safe ham bag. These methods lock in moisture and help keep the slices tender and juicy.
If you add a glaze, unwrap the ham during the final 15 to 30 minutes of cooks time to allow the sugars in the glaze to caramelize to a golden hue.
Step-by-Step Guide to Cooking a Spiral Ham
Follow this easy roadmap for reheating your fully cooked spiral ham to perfection.
Step 1: Preheat the Oven
Set your oven to 275°F to 325°F depending on your time constraints and schedule.
Step 2: Prepare the Ham
Take the ham out of the refrigerator 30–60 minutes before placing in the oven to help it warm to room temperature, which aids in even heating. Rinse the ham if necessary, pat dry, and place it cut-side down on a roasting pan or baking dish.
Tip: Place a shallow pan filled with water on the rack below the ham for added moisture.
Step 3: Cover and Reheat
Cover the pan tightly with aluminum foil—this ensures the ham retains its juices. Place the ham in the oven and let it reheat using the recommended cooking time based on its weight as outlined in the table above.
Step 4: Apply the Glaze
Remove the foil when the ham has about 20–30 minutes left of cook time. Brush your glaze of choice over the top and sides. If the glaze glimmers as it starts to caramelize, you’re on the right track!
Pro Tip for Extra Crispy Glaze
If your glaze doesn’t set to your liking, turn your oven to Broil for the last 3–5 minutes of cooking. Watch it carefully to avoid burning.
Step 5: Let It Rest
Once done, remove the ham from the oven and let it rest for 10–15 minutes before serving. This allows the juices to redistribute, leading to a more flavorful, moist bite.
Common Mistakes and How to Avoid Them
Even seasoned home cooks occasionally make errors when preparing spiral ham. Here are the most common culprits and how to avoid them:
Mistake 1: Overheating the Ham
Because spiral hams are already cooked, exceeding 145°F (63°C) can cause the meat to dry out and become rubbery. Always use a meat thermometer to check internal temperature—and rely more on temperature than clock time.
Mistake 2: Not Covering the Ham
Leaving the ham uncovered during reheating can dry out the meat, especially the exposed top layer. Foil is your friend in this case.
Mistake 3: Glazing Too Early
Apply the glaze too early and you could end up with a burnt, bitter finish. The sugars in most glazes caramelize best during the final portion of heating, so it pays to time your glaze carefully.
Mistake 4: Rushing the Process
Using a high heat setting, like baking at 350°F or higher to speed up the process, increases the risk of tough, chewy meat. Instead, maintain a slower, more controlled temperature to preserve moisture and tenderness.
Storing and Reheating Leftovers
With holiday meals often yielding surplus food, knowing the best way to store and reheat leftover ham is equally important.
Refrigerator Storage
For safe storage in the fridge, place leftovers in an airtight container or tightly wrap with plastic wrap or aluminum foil. They’ll last for 3 to 5 days.
Freezing Spiral Ham
While freezable, ham may lose some moisture and firmness after freezing. If you plan to freeze, wrap tightly in freezer-safe wrapping and store for up to 1 to 2 months. Thaw in the refrigerator before reheating.
Best Way to Reheat Leftovers
To avoid drying out leftover ham, use the following method:
Avoid using the microwave, as it often leads to irregular heating and rubbery texture.

How long does it take to cook a fully cooked spiral ham?
A fully cooked spiral ham generally needs about 10 to 15 minutes per pound when heated at 325°F (163°C). This reheating time ensures that the ham reaches a safe internal temperature of 140°F (60°C) without overcooking or drying out the meat. Since spiral hams are already fully cooked, the goal is to warm them thoroughly while preserving their moisture and flavor.
It’s important to keep the ham covered with foil during heating to trap steam and retain moisture. You can also add a small amount of water or broth to the bottom of the pan for added humidity. Baste occasionally and monitor the internal temperature with a meat thermometer to ensure it does not exceed 140°F (60°C), which could lead to toughness or diminish the quality of the meat.
Why is it necessary to heat a fully cooked spiral ham again?
Even though a fully cooked spiral ham is safe to eat cold right from the package, many people prefer to warm it for enhanced flavor and texture. Reheating helps release the natural juices, improving tenderness and allowing glazes or seasonings to meld more effectively with the meat. It also provides a more appealing experience for holiday meals or special occasions.
Heating also ensures that the ham maintains a warm serving temperature when plated, which is especially important when serving alongside other hot dishes. Additionally, warming the meat slightly can make it easier to carve and serve in clean slices, especially if the ham has been refrigerated beforehand. However, it should not be heated excessively, as this can lead to drying or a loss of the delicate flavor spiral hams are known for.
Can you overheat a fully cooked spiral ham?
Yes, it is possible to overheat a fully cooked spiral ham, and doing so can result in dry, tough, or rubbery meat. Since spiral hams are already fully cooked, their internal temperature only needs to reach 140°F (60°C) to be safely and enjoyably served. Going beyond this temperature range can damage the texture and moistness that make spiral hams a popular choice.
To avoid overheating, use a meat thermometer to monitor the internal temperature of the ham while it heats. Cooking at a moderate oven temperature (325°F or 163°C) and covering the ham with foil can also help in preventing overcooking. If glazing, apply it during the last 20 to 30 minutes of heating to allow it to caramelize without burning.
Should I cover my spiral ham with foil while heating?
Yes, covering your spiral ham with foil while heating is highly recommended to maintain moisture and prevent the outer edges of the meat from drying out or over-browning. Foil helps trap steam inside, creating a more humid cooking environment that mimics the effects of slow steaming and ensures a tender, juicy result.
If you plan to glaze the ham, you can remove the foil for the final 20 to 30 minutes of heating to allow the glaze to caramelize and the surface to brown slightly. Make sure to return the foil loosely over the ham if further heating is needed beyond this point to avoid burning the glaze or drying out the meat unnecessarily.
How do I know when my spiral ham is heated properly?
To determine whether your spiral ham is heated properly, the best method is to use a meat thermometer. Insert the thermometer into the thickest part of the ham, making sure it doesn’t touch the bone or the pan, and ensure that it reaches an internal temperature of 140°F (60°C). This temperature confirms that the ham is fully warmed and ready to be served without being overcooked.
Visual clues such as the ham becoming warm to the touch and the juices running slightly clear can be helpful, but relying on a thermometer is the most accurate approach. If the ham begins to look dry or starts to shrink excessively, it may be close to overcooking, and it should be removed from the oven immediately. Always allow the ham to rest for 10 to 15 minutes after heating, which allows the juices to redistribute.
Is it possible to cook a spiral ham in a slow cooker?
Yes, a slow cooker can be an excellent method for reheating a spiral ham without drying it out. For best results, slice the ham into manageable portions that can fit inside your slow cooker and place them cut-side down. Add a small amount of water, broth, or glaze to the bottom to help maintain moisture. On the low setting, the ham should be warmed through within 2 to 4 hours, depending on the size and your slow cooker’s heat settings.
Care must be taken not to leave the ham in the slow cooker for too long, as spiral hams can become mushy or overly soft if kept warm for several hours beyond being heated through. If using a glaze, add it in the final 30 minutes of cooking to encourage caramelization and prevent burning. Monitor the ham regularly and use a meat thermometer to ensure the internal temperature does not exceed 140°F (60°C).
How long can I leave a reheated spiral ham safe at room temperature?
Once reheated, a spiral ham should not be left at room temperature for more than two hours to avoid bacterial growth and foodborne illness. The danger zone for bacterial development is between 40°F (4°C) and 140°F (60°C), so it’s important to either keep the ham hot (above 140°F) on a warming tray or refrigerate it promptly if it will not be consumed within this time frame.
If you are serving at a party or event, consider rotating the ham platter with freshly reheated portions to preserve food safety. After two hours at room temperature, any remaining ham should be refrigerated. When stored properly in an airtight container, cooked ham can last in the refrigerator for up to 4 days and can be gently reheated again using a low-temperature oven or microwave without compromising texture or flavor.
