When it comes to preparing a ham for a special occasion like Christmas dinner, it's important to know whether the ham is fully cooked or not. While most ham sold in the U.S. is cured and fully cooked, there are still some variations that require additional cooking. Let's explore the different types of ham and how to properly prepare them.
Types of Ham
Ham is typically derived from the hind leg of a hog, ranging from the middle of the shank bone to the hip bone. The upper part, known as the butt end, is often considered more flavorful due to its higher fat content. However, there are other types of ham to be aware of:
- Picnic Ham: This is actually pork shoulder that has been cured to taste like regular ham.
- Whole Fresh Hams: These are uncured ham meat that resembles pork more than traditional ham.
- Turkey Ham: This is a ham made from turkey meat, offering a different flavor profile.
It's important to note that different types of ham may have different cooking requirements, so always refer to the label for specific instructions.
City Ham vs. Country Ham
The majority of ham sold in the U.S. is known as city ham. This type of ham is wet-cured with brine and often smoked or injected with smoke flavoring. While cooking may occur during this process, it's still crucial to check the label for cooking instructions.

On the other hand, country ham is dry-cured with salt and then hung to dry for several months. It is often smoked as well. Country ham tends to be saltier than city ham and requires soaking in water for hours to reduce the saltiness before cooking.
Is Smoked Ham Fully Cooked?
Most smoked ham sold in the U.S. is fully cooked and ready to eat. However, even if the ham is fully cooked, it can still take several hours to warm in the oven. For example, a 6-pound bone-in cooked smoked ham would take approximately 5 hours to heat to an internal temperature of 140 degrees Fahrenheit.
It's important to follow the preparation guidelines on the label to ensure that the ham is fully cooked and safe to eat. Some hams may have the appearance of being ready-to-eat but require additional cooking. Look for labels that say cook thoroughly or similar instructions.
How to Reheat Smoked Ham
If you have a spiral-sliced ham, it is safe to eat without reheating. However, if you prefer to serve it warm, be cautious not to dry it out. Cover the ham with heavy foil and heat it at 325 degrees Fahrenheit for approximately 10 minutes per pound, or until it reaches an internal temperature of 140 degrees Fahrenheit.
Leftover ham or spiral ham that has been repackaged outside of the original facility should be heated to an internal temperature of 165 degrees Fahrenheit.
When it comes to smoked hams, most are fully cooked and ready to eat. However, it's essential to read the label and follow the cooking instructions provided. Different types of ham may have varying cooking requirements, so it's crucial to ensure that the ham reaches the appropriate internal temperature for safe consumption. By properly preparing and reheating smoked ham, you can enjoy a delicious and safe meal for any special occasion.
