Precooked hams are a holiday staple for many families, offering a convenient and delicious centerpiece for special occasions. However, knowing exactly how long to cook a precooked ham can be tricky. After all, it’s already cooked! The goal isn’t to cook it through, but rather to heat it properly, enhance its flavor, and achieve that beautiful, slightly caramelized exterior. This comprehensive guide will take you through everything you need to know to ensure your precooked ham is a resounding success.
Understanding Precooked Hams
Before diving into cooking times, let’s clarify what a precooked ham actually is. These hams have already been fully cooked during the processing stage, meaning they’re safe to eat right out of the package. The cooking you’ll be doing at home is simply to bring it to the optimal serving temperature and improve its taste and texture.
Different types of precooked hams exist, and these variations can influence cooking times slightly. Common types include:
- Spiral-cut hams: These are pre-sliced for easy serving and tend to heat faster.
- Bone-in hams: They retain more moisture during cooking and generally take a bit longer to heat.
- Boneless hams: These are the most convenient and usually heat the quickest.
- City hams: Cured and smoked, these are the most common type of precooked ham.
- Country hams: Salt-cured and often smoked, they require special preparation and may not be fully cooked.
Understanding the type of ham you have is the first step towards calculating the correct cooking time. Always refer to the packaging instructions for specific guidance from the manufacturer.
Calculating Cooking Time: The Golden Rule
The general rule of thumb for heating a precooked ham is to cook it for 10-15 minutes per pound at 325°F (160°C). However, this is just a guideline, and several factors can affect the actual cooking time.
It’s crucial to use a meat thermometer to ensure the ham reaches an internal temperature of 140°F (60°C). This temperature is considered safe and provides the best flavor and texture.
Always place the thermometer in the thickest part of the ham, avoiding the bone.
Factors Affecting Cooking Time
Several factors can influence how long it takes to heat a precooked ham, so you should consider these when planning your cooking schedule.
- Ham Size: Obviously, a larger ham will take longer to heat than a smaller one.
- Bone-in vs. Boneless: Bone-in hams generally take longer due to the bone acting as an insulator.
- Starting Temperature: If the ham is ice-cold from the refrigerator, it will take longer to heat than if it has been allowed to sit at room temperature for a short period. Don’t leave it at room temperature for more than two hours.
- Oven Temperature Accuracy: Not all ovens are created equal. Use an oven thermometer to ensure your oven is accurately set to 325°F (160°C).
- Oven Type: Convection ovens may cook the ham faster than conventional ovens due to better heat circulation.
- Covering the Ham: Covering the ham with foil can help retain moisture and shorten cooking time, but removing the foil towards the end allows for browning.
A Simple Cooking Time Chart
While the 10-15 minutes per pound rule is useful, here’s a more detailed chart based on ham type and weight:
| Ham Type | Weight (lbs) | Estimated Cooking Time (Hours) | Internal Temperature |
| ————- |:————-:|:——————————-:|:———————-:|
| Bone-in | 7-9 | 1.2 – 2.2 | 140°F (60°C) |

How long should I cook a fully cooked ham in the oven?
A fully cooked ham primarily needs reheating, not cooking. The goal is to bring the internal temperature up to a safe and palatable level. For a fully cooked ham, you’ll want to bake it at 325°F (163°C) for approximately 10-15 minutes per pound. Keep a close eye on the internal temperature using a meat thermometer.
It’s crucial not to overcook the ham, as this can dry it out. Insert the meat thermometer into the thickest part of the ham, avoiding the bone. You’re aiming for an internal temperature of 140°F (60°C). Remember, letting the ham rest for about 15 minutes after removing it from the oven will allow the juices to redistribute, resulting in a more flavorful and moist final product.
What temperature is best for cooking a precooked ham?
The ideal oven temperature for reheating a precooked ham is 325°F (163°C). This lower temperature allows the ham to heat gently and evenly without drying out the exterior too quickly. Higher temperatures can lead to a tough, dry ham, while lower temperatures may take an unnecessarily long time.
Baking at 325°F ensures that the ham is heated through to a safe and enjoyable temperature of 140°F without compromising its moisture content. While some recipes suggest higher temperatures for the last few minutes to caramelize a glaze, the majority of the reheating process should be done at this lower temperature for best results.
Should I cover the ham while it’s baking?
Yes, covering the ham while baking is highly recommended, especially during the initial stages of reheating. Covering the ham with foil helps to retain moisture and prevent the surface from drying out or burning. This is particularly important if you’re dealing with a leaner ham or one that’s been stored for a longer period.
To cover the ham, you can use aluminum foil. Tent the foil loosely over the ham, ensuring it doesn’t touch the surface too tightly, which could cause steaming instead of baking. For the last 30 minutes of cooking, you can remove the foil to allow the ham’s exterior to develop a slightly crispier texture and allow any glaze to caramelize properly.
How do I know when my precooked ham is done?
The most accurate way to determine if your precooked ham is ready is to use a meat thermometer. Insert the thermometer into the thickest part of the ham, avoiding the bone. You’re looking for an internal temperature of 140°F (60°C). This ensures the ham is heated through safely and effectively.
Visual cues can be misleading, as the ham may appear done on the outside while still being cold in the center. Relying solely on time estimates can also lead to overcooking. The meat thermometer is your best friend in achieving a perfectly heated and juicy ham. Remember to let the ham rest for 15 minutes before carving to allow the juices to redistribute.
Can I cook a precooked ham in a slow cooker?
Yes, you can absolutely cook a precooked ham in a slow cooker, and it can be a fantastic way to keep it moist and tender. This method is especially useful if you’re short on oven space or want a hands-off cooking approach. Place the ham cut-side down in the slow cooker, and add about a cup of liquid, such as water, broth, or even apple juice, to the bottom.
Cook on low for 4-6 hours or on high for 2-3 hours, or until the internal temperature reaches 140°F (60°C), using a meat thermometer. You can add a glaze during the last hour of cooking by brushing it over the ham. Be sure to check the ham’s internal temperature regularly to avoid overcooking, as slow cookers can vary in heat intensity.
What if my ham is already sliced? Does that affect the cooking time?
Yes, having a pre-sliced ham can slightly affect the cooking time and moisture retention. Sliced ham has more surface area exposed, which can lead to it drying out more quickly during the reheating process. Therefore, it’s crucial to pay close attention to the internal temperature and avoid overcooking.
Reduce the cooking time by a few minutes per pound compared to an unsliced ham. Be sure to cover the sliced ham tightly with foil to minimize moisture loss during baking. You can also add a bit of moisture by placing a small amount of water or broth in the bottom of the baking dish. Check the internal temperature frequently to ensure it reaches 140°F (60°C) without becoming dry.
What is the best way to add a glaze to a precooked ham?
The best way to add a glaze to a precooked ham is to apply it during the last 30-45 minutes of cooking. This allows the glaze to caramelize and develop a rich flavor without burning. Begin by removing the foil covering from the ham and then generously brush the glaze over the entire surface.
Return the ham to the oven, uncovered, and continue baking until the glaze is glossy and slightly sticky. You can baste the ham with the glaze a few more times during this final stage to build up a thicker, more flavorful crust. Be mindful of the oven temperature to prevent the glaze from burning; a slightly lower temperature might be necessary for heavily sugared glazes.
