Ham, a culinary centerpiece for holidays, celebrations, and simple family dinners, is a crowd-pleaser. However, many home cooks find themselves pondering a crucial question: How long do I actually cook a cooked ham? It seems straightforward, but achieving that perfectly moist, flavorful ham requires understanding the nuances of different ham types, cooking methods, and internal temperatures. This guide will walk you through everything you need to know, ensuring your ham is a delicious success.
Understanding Cooked Ham Varieties
The term “cooked ham” is somewhat of a misnomer. Most hams you find in the grocery store have already been cured and smoked, meaning they’ve technically been “cooked” to some extent. The cooking you do at home is primarily to reheat it to a safe and palatable temperature, and potentially add a glaze for extra flavor. There are a few main types to consider.
Fully Cooked Hams
These hams are the most common and convenient. They’ve been cooked to an internal temperature safe for consumption, meaning you could technically eat them straight from the package (though reheating is recommended for optimal flavor and texture). Fully cooked hams need to be heated to an internal temperature of 140°F (60°C).
Spiral-Cut Hams
A spiral-cut ham is simply a fully cooked ham that has been pre-sliced in a spiral pattern. This makes serving incredibly easy, but it also means the ham can dry out more quickly during reheating. Pay special attention to keeping spiral-cut hams moist.
City Ham vs. Country Ham
While both are “cooked” at some point, city hams are typically wet-cured and fully cooked, making them readily available for reheating. Country hams, on the other hand, are dry-cured and often require additional cooking to reach a safe and enjoyable eating temperature. We’ll primarily focus on city hams in this guide, as they’re the most common type found in supermarkets.
Determining Cooking Time: The Key Factors
Calculating the correct cooking time for your cooked ham involves considering a few important elements.
Ham Weight
The most significant factor determining cooking time is the weight of your ham. Larger hams naturally require longer reheating periods. Generally, plan on a specific number of minutes per pound.
Bone-In vs. Boneless
Bone-in hams take slightly longer to heat through than boneless hams of the same weight. The bone acts as an insulator, slowing down the cooking process.
Oven Temperature
A lower oven temperature will require a longer cooking time, while a higher temperature will shorten it. However, high heat can also dry out the ham, so a moderate oven temperature is usually best.
Cooking Method
Different cooking methods, such as baking, roasting, or using a slow cooker, will affect the cooking time. We’ll focus primarily on oven baking in this guide.
Calculating Cooking Time: Minutes per Pound
The general rule of thumb for reheating a fully cooked ham in the oven is to cook it at 325°F (160°C) for a certain number of minutes per pound. For fully cooked hams, aim for 10-15 minutes per pound. For spiral-cut hams, sticking closer to the 10-minute mark is recommended to prevent drying out. Remember to check the internal temperature with a meat thermometer to ensure it reaches 140°F (60°C).
Example Calculation
Let’s say you have a 8-pound fully cooked ham. Using the 10-15 minutes per pound guideline:
- Minimum cooking time: 8 pounds x 10 minutes/pound = 80 minutes (1 hour and 20 minutes)
- Maximum cooking time: 8 pounds x 15 minutes/pound = 120 minutes (2 hours)
Start checking the internal temperature after 80 minutes and continue cooking until it reaches 140°F (60°C).
Step-by-Step Guide to Cooking a Cooked Ham
Following these steps will help you achieve a perfectly heated and flavorful ham.
Preparation
- Remove the ham from the refrigerator at least 30 minutes before cooking to allow it to come closer to room temperature. This will promote more even heating.
- Preheat your oven to 325°F (160°C).
- Prepare your roasting pan. A roasting pan with a rack is ideal, as it allows the heat to circulate evenly around the ham. If you don’t have a rack, you can create one by layering vegetables like onions, carrots, and celery in the bottom of the pan.
- Optionally, score the ham. If you’re using a whole ham (not spiral-cut), you can score the fat in a diamond pattern. This will help render the fat and allow the glaze to penetrate deeper into the ham. Be careful not to cut too deep into the meat.
Cooking
- Place the ham in the roasting pan. If it’s a bone-in ham, place it cut-side down.
- Add moisture to the pan. Pour about 1 cup of water or broth into the bottom of the roasting pan. This will help create steam and keep the ham moist.
- Cover the ham. Tent the ham loosely with aluminum foil. This will prevent the surface from drying out too quickly.
- Bake according to the calculated time. Remember to use the guidelines of 10-15 minutes per pound at 325°F (160°C).
- Check the internal temperature. About 30 minutes before the estimated cooking time is up, start checking the internal temperature with a meat thermometer. Insert the thermometer into the thickest part of the ham, avoiding the bone.
- Glaze the ham (optional). If you’re using a glaze, apply it during the last 30 minutes of cooking. Remove the foil, brush the glaze evenly over the ham, and return it to the oven to finish cooking. You may want to baste it a few times.
Finishing
- Remove the ham from the oven when it reaches an internal temperature of 140°F (60°C).
- Let the ham rest. Cover the ham loosely with foil and let it rest for at least 15-20 minutes before carving. This allows the juices to redistribute, resulting in a more moist and flavorful ham.
Tips for a Moist and Delicious Ham
Preventing your ham from drying out is key to a delicious final product. Here are some tips to help:
- Don’t overcook it. The most common reason for dry ham is overcooking. Rely on a meat thermometer to ensure you reach the correct internal temperature without exceeding it.
- Use a glaze. Glazes not only add flavor but also help to seal in moisture.
- Tent with foil. Covering the ham with foil during the initial cooking period helps to retain moisture.
- Add moisture to the pan. Adding water or broth to the roasting pan creates steam, which helps to keep the ham moist.
- Consider a ham bag. Ham bags are designed to keep hams moist during cooking. You can soak the bag in water before placing the ham inside.
Creative Glaze Ideas
A glaze can elevate your ham from simple to spectacular. Here are a few ideas to inspire you:
- Honey-Mustard Glaze: Combine honey, Dijon mustard, brown sugar, and a touch of vinegar.
- Brown Sugar-Pineapple Glaze: Mix brown sugar, pineapple juice, ground cloves, and a dash of cinnamon.
- Maple-Bourbon Glaze: Combine maple syrup, bourbon, brown sugar, and a pinch of cayenne pepper.
- Cherry Glaze: Mix cherry preserves, red wine vinegar, Dijon mustard, and a pinch of black pepper.
Serving and Storing Leftover Ham
Once your ham is cooked to perfection, it’s time to serve and enjoy.
Carving Techniques
- For bone-in hams: Use a sharp carving knife to slice around the bone, then separate the meat from the bone. Carve the meat into slices, following the natural grain.
- For spiral-cut hams: The ham is already pre-sliced, so simply loosen the slices with a knife and serve.
Serving Suggestions
Ham pairs well with a variety of side dishes, including:
- Mashed potatoes
- Sweet potato casserole
- Green bean casserole
- Macaroni and cheese
- Dinner rolls
- Asparagus
Storing Leftover Ham
To store leftover ham properly:
- Let the ham cool completely before storing.
- Wrap the ham tightly in plastic wrap or aluminum foil.
- Store the ham in the refrigerator for up to 3-4 days.
- You can also freeze leftover ham for longer storage. Wrap it tightly in freezer-safe wrap and store it for up to 2-3 months.
Troubleshooting Common Ham Problems
Even with careful planning, things can sometimes go awry. Here are some solutions to common ham problems:
- Dry ham: If your ham is dry, try basting it with pan juices or broth. You can also cover it with foil and let it steam in the oven for a short period.
- Uneven cooking: If your ham is cooking unevenly, rotate it in the oven. You can also cover the thinner parts with foil to prevent them from overcooking.
- Glaze burning: If your glaze is burning, reduce the oven temperature or cover the ham loosely with foil.
By following these guidelines and tips, you’ll be well-equipped to cook a delicious and perfectly heated cooked ham every time. Enjoy!
How do I determine if my cooked ham is truly ready to eat, even though it’s already cooked?
A fully cooked ham, though already safe to eat, benefits greatly from being heated through to enhance its flavor and texture. The internal temperature is your best indicator of readiness. Aim for an internal temperature of 140°F (60°C) for hams that are pre-cooked and intended to be reheated. Use a meat thermometer inserted into the thickest part of the ham, avoiding bone, to get an accurate reading.
Reaching this temperature ensures the ham is warmed evenly and provides a more enjoyable eating experience. While you could technically eat a fully cooked ham cold, reheating it to the recommended temperature brings out the best in the meat, making it more tender and flavorful. Remember to let the ham rest for a few minutes after removing it from the oven before carving.
What is the ideal oven temperature for reheating a cooked ham?
The optimal oven temperature for reheating a cooked ham is generally between 325°F (163°C) and 350°F (177°C). These moderate temperatures allow the ham to warm evenly without drying out. Lower temperatures are preferable, as they reduce the risk of overheating the outside of the ham before the inside is fully warmed.
Using a slightly lower temperature and a longer cooking time results in a more tender and juicy ham. Monitor the internal temperature carefully using a meat thermometer. You can also tent the ham with foil to help retain moisture, especially during the initial stages of reheating.
How long should I cook a cooked ham per pound?
As a general guideline, plan to cook a fully cooked ham for approximately 10-15 minutes per pound at 325°F (163°C). This timeframe is a good starting point, but it’s crucial to monitor the internal temperature with a meat thermometer to ensure accuracy. The cooking time will vary depending on the ham’s starting temperature, size, and whether it’s bone-in or boneless.
Remember that the goal isn’t to “cook” the ham, but to gently warm it through to an internal temperature of 140°F (60°C). Check the temperature periodically, starting about an hour before you expect it to be done. Adjust the cooking time accordingly based on your thermometer readings.
Should I cover the ham while cooking it?
Covering the ham during the initial stages of reheating is highly recommended. This helps to retain moisture and prevent the surface from drying out. Use aluminum foil to create a tent over the ham, ensuring it’s loosely sealed. This will trap steam and keep the ham juicy.
About 30 minutes before the estimated end of the cooking time, remove the foil to allow the ham to brown and the glaze, if any, to caramelize. This brief period of uncovered cooking adds visual appeal and enhances the flavor of the ham’s surface.
What’s the best way to add a glaze to my cooked ham?
Applying a glaze to a cooked ham adds a delicious layer of flavor and visual appeal. The best time to add the glaze is during the last 30 to 45 minutes of cooking. This allows the glaze to caramelize and adhere properly to the ham’s surface. Brush the glaze evenly over the ham, repeating several times for a richer flavor.
Ensure the ham is uncovered when applying the glaze. This allows the sugars in the glaze to brown and create a beautiful, glossy finish. Consider using a glaze that complements the ham’s flavor profile, such as a honey mustard glaze, a brown sugar glaze, or a fruit-based glaze.
What if my ham is spiral-cut? Does that change the cooking time?
Spiral-cut hams tend to cook a bit faster than whole hams because they have more surface area exposed to the heat. The cooking time per pound may be slightly less, around 8-12 minutes per pound at 325°F (163°C). However, it’s still critical to use a meat thermometer to ensure it reaches the desired internal temperature of 140°F (60°C).
Spiral-cut hams are also more prone to drying out, so it’s particularly important to keep them covered with foil during the initial stages of reheating. Consider adding a small amount of liquid, such as apple juice or broth, to the bottom of the roasting pan to help maintain moisture.
How long should I let the ham rest after cooking before carving?
Allowing the ham to rest after cooking is a crucial step often overlooked. Let the ham rest for at least 10-15 minutes before carving. This allows the juices to redistribute throughout the meat, resulting in a more tender and flavorful ham.
Cover the ham loosely with foil during the resting period to keep it warm. Carving the ham immediately after removing it from the oven will cause the juices to run out, leaving you with a drier final product. Patience is key to achieving a perfectly cooked and juicy ham.
