The Basics of Cooking a Fully Cooked Ham

Before we dive into the nitty-gritty of cooking times, let’s cover the basics. A fully cooked ham is, as the name suggests, already cooked when you purchase it. This means that it’s been smoked, cured, or cooked to an internal temperature of at least 140°F (60°C), making it safe to eat directly out of the package. However, many of us prefer to reheat or glaze our ham to add extra flavor and texture. This is where oven-roasting comes into play.

Choosing the Right Ham

When selecting a fully cooked ham, you’ll encounter various types, each with its own unique characteristics. Some popular options include:

Bone-in ham: This type of ham is more traditional and has a bone running through the center. It’s often more flavorful and tender, but can be more challenging to carve.
Boneless ham: A boneless ham is, as the name implies, without a bone. It’s often easier to carve and serves as a more convenient option for ham enthusiasts.
Spiral-cut ham: A spiral-cut ham is a boneless ham that’s been pre-sliced into thin, uniform pieces. It’s an excellent choice for those who want to minimize effort and maximize presentation.

Oven-Roasting a Fully Cooked Ham: Factors to Consider

Now that we’ve covered the basics, let’s explore the key factors that influence the cooking time of a fully cooked ham in the oven.

Ham Size and Shape

The size and shape of your ham play a significant role in determining the cooking time. A larger ham will, naturally, take longer to heat through than a smaller one. Here are some general guidelines to keep in mind:

Small ham (5-7 pounds): 15-20 minutes per pound
Medium ham (7-10 pounds): 20-25 minutes per pound
Large ham (10-12 pounds): 25-30 minutes per pound

Oven Temperature

The oven temperature you choose will also impact the cooking time. A higher temperature will result in a faster cooking time, but may also lead to a less tender ham.

325°F (160°C): A lower temperature that’s ideal for large hams or those who prefer a more tender, juicy texture.
350°F (175°C): A moderate temperature that’s suitable for most hams and provides a nice balance between speed and tenderness.
375°F (190°C): A higher temperature that’s best for smaller hams or those who prefer a crispy, caramelized glaze.

Glazing and Browning

If you’re looking to add an extra layer of flavor and texture to your ham, glazing and browning are essential considerations. A glaze is a sweet or savory sauce that’s brushed onto the ham during the last 30 minutes of cooking, while browning refers to the caramelization of the ham’s surface.

Glazing: Add an extra 10-15 minutes to the cooking time to allow the glaze to set and caramelize.
Browning: Increase the oven temperature to 400°F (200°C) for the last 15-20 minutes of cooking to achieve a crispy, golden-brown crust.

Cooking Times for a Fully Cooked Ham in the Oven

Now that we’ve explored the various factors that influence cooking time, let’s provide some general guidelines for oven-roasting a fully cooked ham.

Cooking Times per Pound

Here are some estimated cooking times per pound for a fully cooked ham in the oven:

Cooking Times with Glazing and Browning

If you’re planning to glaze and brown your ham, add the following times to the estimates above:

Glazing: Add 10-15 minutes to the cooking time.
Browning: Add 15-20 minutes to the cooking time.

Additional Tips and Tricks

To ensure your fully cooked ham turns out perfectly, here are some additional tips and tricks to keep in mind:

Score the fat: Use a sharp knife to score the fat layer on the surface of the ham in a diamond pattern. This will help the glaze penetrate deeper and create a more appealing presentation.
Use a meat thermometer: Always use a meat thermometer to ensure the internal temperature of the ham reaches 140°F (60°C).
Let it rest: Once the ham is cooked, remove it from the oven and let it rest for 10-15 minutes before slicing and serving. This will allow the juices to redistribute, making the ham even more tender and flavorful.

By following these guidelines and considering the various factors that influence cooking time, you’ll be well on your way to creating a mouth-watering, oven-roasted fully cooked ham that’s sure to impress your family and friends. Remember to always prioritize food safety, use a meat thermometer, and let the ham rest before serving. Happy cooking!

What’s the best way to store a fully cooked ham before cooking it in the oven?

Store your fully cooked ham in the refrigerator at a temperature of 40°F (4°C) or below. Make sure it is wrapped tightly in plastic wrap or aluminum foil to prevent drying out. You can also store it in a leak-proof bag or airtight container. If you’re not planning to cook the ham within a few days, consider freezing it. Wrap the ham tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. Frozen cooked ham can be stored for up to 2 months.

When you’re ready to cook the ham, remove it from the refrigerator or freezer and let it sit at room temperature for about 30 minutes before placing it in the oven. This helps the ham cook more evenly and prevents it from cooking too quickly on the outside.

How do I know if my oven is at the right temperature?

To ensure your oven is at the right temperature, use an oven thermometer. Place the thermometer on the middle rack of the oven and set it to the desired temperature (in this case, 325°F or 160°C). Wait for about 10-15 minutes to allow the oven to preheat. Then, check the thermometer to see if it matches the temperature you set. If it doesn’t, adjust the oven temperature accordingly.

It’s essential to use an oven thermometer because oven temperatures can vary. Even if your oven says it’s at the right temperature, it might not be accurate. An oven thermometer gives you an exact reading, ensuring your ham cooks evenly and at the right temperature.

Can I glaze my ham during the last 30 minutes of cooking?

Yes, you can glaze your ham during the last 30 minutes of cooking. In fact, it’s a great way to add extra flavor and a caramelized crust to your ham. Simply prepare your glaze by mixing together your desired ingredients (such as brown sugar, mustard, and spices), and brush it evenly over the ham. You can apply the glaze once or multiple times during the last 30 minutes of cooking, depending on how caramelized you want the crust to be.

Just be careful not to open the oven door too frequently, as this can cause the ham to dry out. Try to glaze the ham during the last 30 minutes, and then let it cook undisturbed for the remaining time. This will help the glaze stick to the ham and create a beautiful, caramelized crust.

How do I prevent my ham from drying out in the oven?

To prevent your ham from drying out in the oven, make sure to score the fat layer in a diamond pattern. This helps the fat melt and baste the ham as it cooks, keeping it moist and juicy. You can also cover the ham with aluminum foil or a foil tent during the first 30 minutes of cooking to prevent it from drying out.

Another tip is to cook the ham at a low and steady temperature (325°F or 160°C). This ensures the ham cooks slowly and evenly, reducing the risk of drying out. Finally, don’t overcook the ham. Cook it until it reaches an internal temperature of 140°F (60°C), which is the recommended minimum internal temperature for cooked ham.

Can I cook a fully cooked ham at a higher temperature to save time?

While it’s tempting to cook a fully cooked ham at a higher temperature to save time, it’s not recommended. Cooking the ham at a higher temperature can cause it to dry out and become tough. Fully cooked hams are best cooked at a low and steady temperature of 325°F (160°C) to ensure they remain juicy and tender.

Cooking at a higher temperature can also cause the glaze to burn or become too caramelized, which can affect the flavor and texture of the ham. If you’re short on time, consider using a different cooking method, such as grilling or pan-frying, which can cook the ham more quickly. However, for oven-cooking, it’s best to stick to the recommended temperature and cooking time.

Can I refrigerate or freeze leftover cooked ham?

Yes, you can refrigerate or freeze leftover cooked ham. Refrigerate the ham within 2 hours of cooking and store it in a shallow, airtight container. It will keep for 3 to 4 days in the refrigerator. If you don’t plan to use it within that timeframe, consider freezing it. Wrap the ham tightly in plastic wrap or aluminum foil and place it in a freezer-safe bag. Frozen cooked ham can be stored for up to 2 months.

When you’re ready to use the leftover ham, remove it from the refrigerator or freezer and let it come to room temperature. You can then use it in a variety of dishes, such as soups, salads, or sandwiches. Reheat the ham to an internal temperature of 165°F (74°C) to ensure food safety.

How do I carve a fully cooked ham?

To carve a fully cooked ham, start by letting it rest for about 10-15 minutes after cooking. This allows the juices to redistribute, making it easier to carve. Remove the ham from the oven and transfer it to a carving board. Use a sharp knife to slice the ham into thin strips, cutting against the grain. You can also use a ham slicer or an electric knife to make the job easier.

When carving the ham, try to cut in smooth, even strokes, applying gentle pressure. This helps to prevent the ham from tearing or crumbling. You can also carve the ham into thicker slices or wedges, depending on your preference. Once carved, serve the ham hot, garnished with your choice of herbs or sides.
