Hosting a holiday dinner or a large family gathering often feels like a high-stakes game of Tetris. Between the side dishes, the homemade rolls, and the dessert, your main oven is usually working overtime. This is where the electric roaster oven becomes the unsung hero of the kitchen. Learning how to make a ham in an electric roaster not only frees up your oven space but also provides a controlled environment that helps keep the meat incredibly moist. Because a roaster is smaller than a traditional oven, it holds onto steam more effectively, ensuring that your centerpiece ham doesn’t dry out during the reheating process.
Why Use an Electric Roaster for Ham?
The electric roaster is essentially a portable, countertop oven. However, it has a few distinct advantages when it comes to cooking a large cut of meat like a bone-in or spiral-sliced ham. First and foremost is the convenience of portability. You can set it up on a side table or even in the garage if your kitchen is crowded.
Secondly, the heat distribution in an electric roaster is quite unique. The heating elements are located in the sides rather than the bottom, which reduces the risk of scorching the underside of the meat. Furthermore, because the lid fits tightly and the cooking well is relatively small compared to a full-sized oven, the moisture released from the ham stays trapped inside. This creates a self-basting environment that is perfect for lean cuts of pork.
Selecting the Right Ham for Your Roaster
Before you plug in your appliance, you need to choose the right ham. Most hams sold in grocery stores are “city hams,” which means they are already cured and fully cooked. When you “cook” these at home, you are actually just reheating them to a safe and palatable temperature.
Bone-In vs. Boneless
A bone-in ham generally offers better flavor and a more traditional appearance. The bone also helps conduct heat into the center of the meat. Boneless hams are easier to slice and fit more easily into smaller roaster ovens. If you are feeding a large crowd, a 10 to 15-pound bone-in ham is usually the gold standard.
Spiral-Sliced vs. Whole
Spiral-sliced hams are incredibly convenient because the work of carving is already done for you. However, they are more prone to drying out because the internal juices can escape through the pre-cut slices. If you choose a spiral-sliced ham for your electric roaster, you must be extra diligent about your liquid levels and cooking time.
Preparing the Electric Roaster
Preparation is the key to a stress-free cooking experience. Start by ensuring your roaster is clean and placed on a heat-safe surface. Always use the rack that comes with the roaster. Placing the ham directly on the bottom of the insert can lead to uneven cooking and may cause the sugars in the ham glaze to burn.
Add a small amount of liquid to the bottom of the roaster pan. This could be water, chicken broth, apple juice, or even a bit of white wine. You only need about half a cup to an inch of liquid. This liquid will turn into steam, which is the secret weapon for a juicy ham.
Step-by-Step Instructions for Cooking the Ham
-
Step 1: Preheating
Set your electric roaster to 325 degrees Fahrenheit. It is important to let the roaster preheat fully before placing the ham inside. This usually takes about 15 to 20 minutes. While it preheats, take your ham out of the refrigerator. Letting it sit at room temperature for about 30 minutes before cooking helps it heat more evenly.

Step 2: Preparing the Ham
Remove all packaging, including the plastic disc that is often found on the bone end of the ham. If you are using a whole (not spiral-sliced) ham, you can score the fat in a diamond pattern. This looks beautiful and allows any glaze you apply later to penetrate the meat. Place the ham on the roaster rack, fat side up. As the fat melts, it will naturally baste the meat.
-
Step 3: The Initial Heat
Place the lid on the roaster and resist the urge to peek. Every time you lift the lid, you lose a significant amount of heat and moisture. For a fully cooked ham, you are looking to reach an internal temperature of 140 degrees Fahrenheit. A general rule of thumb for timing is 15 to 20 minutes per pound.
-
Step 4: Applying the Glaze
If you plan on using a glaze, wait until the last 30 to 45 minutes of the cooking process. If you apply a sugar-based glaze too early, it will burn and create a bitter crust. Carefully lift the lid, brush the glaze generously over the ham, and quickly replace the lid. You may want to turn the heat up to 375 degrees Fahrenheit for these final minutes to help the glaze caramelize and become tacky.
Monitoring the Temperature
The only way to be 100% sure your ham is ready is to use a meat thermometer. Insert the probe into the thickest part of the meat, making sure not to touch the bone, as the bone registers heat differently than the meat.
For a “Ready-to-Eat” ham (which most are), you want to reach 140 degrees Fahrenheit. If you have purchased a “Cook-before-Eating” ham, you must reach an internal temperature of 145 degrees Fahrenheit followed by a three-minute rest. Using an electric roaster makes it easy to maintain a steady temperature, but it is always better to check early rather than late.
Resting and Carving
Once the ham reaches its target temperature, use the handles on the roaster rack to carefully lift the ham out of the roaster. Place it on a large cutting board or a serving platter. This is the most important step: let the ham rest for at least 15 to 20 minutes.
During the resting period, the muscle fibers relax and reabsorb the juices. If you cut into the ham immediately, all that delicious moisture will run out onto the board, leaving you with dry meat. Cover it loosely with aluminum foil to keep it warm while it rests.
Tips for the Best Roaster Ham
To elevate your ham from good to great, consider these professional tips.
- First, if your ham is particularly large and touches the lid of the roaster, create a “tent” with heavy-duty aluminum foil over the ham before putting the lid on. This prevents the skin from sticking to the lid and helps distribute heat.
- Second, don’t be afraid to experiment with your steaming liquid. Using ginger ale or pineapple juice in the bottom of the pan adds a subtle sweetness to the steam that permeates the meat. You can also throw in a few cloves or a cinnamon stick into the liquid for a festive aroma.
Cleaning Your Electric Roaster
One of the reasons people love electric roasters is the easy cleanup, provided you do it right. Once the ham is out, unplug the roaster and let it cool. Most roaster inserts are removable and can be soaked in the sink with warm, soapy water. If you have stubborn burnt-on glaze, a paste of baking soda and water left to sit for an hour will usually do the trick. Many modern inserts are even dishwasher safe, but always check your manufacturer’s manual first.
Creative Ways to Use Leftovers
A 10-pound ham usually results in plenty of leftovers. Beyond the standard ham sandwich, consider dicing the ham for a breakfast quiche, tossing it into a split pea soup, or adding it to a creamy carbonara pasta. The bone itself is a goldmine of flavor; save it in the freezer to use as a base for stocks, beans, or stews later in the year.
FAQs
-
How long does it take to cook a ham in an electric roaster?
For a fully cooked bone-in ham, you should plan on approximately 15 to 20 minutes per pound when the roaster is set to 325 degrees Fahrenheit. A 10-pound ham will typically take between 2.5 and 3 hours to reach the desired internal temperature of 140 degrees Fahrenheit. Always use a meat thermometer to verify doneness rather than relying solely on the clock.
-
Do I need to add water to the bottom of the roaster?
While it is not strictly mandatory, adding about 1 to 2 cups of liquid (water, broth, or juice) to the bottom of the roaster is highly recommended. The electric roaster is a small environment, and the liquid creates steam that prevents the ham from drying out during the long heating process. Ensure the ham stays on the rack so it is steaming rather than boiling in the liquid.
-
Can I cook a frozen ham in an electric roaster?
It is strongly recommended to completely thaw your ham in the refrigerator before cooking it in an electric roaster. Cooking a frozen ham can lead to uneven heating, where the outside becomes overcooked and dry while the center remains dangerously cold. Thawing a large ham can take 24 to 48 hours, so plan ahead.
-
How do I keep a spiral-sliced ham from drying out in the roaster?
Spiral-sliced hams are more delicate. To keep them moist, wrap the entire ham tightly in heavy-duty aluminum foil before placing it on the rack inside the roaster. This seals in the juices. You can open the foil during the last 20 minutes of cooking to apply a glaze and allow the exterior to brown slightly.
-
What temperature should a ham be when it is done?
For most hams purchased at the store, which are labeled “fully cooked” or “ready to eat,” you only need to heat them to an internal temperature of 140 degrees Fahrenheit. This is the temperature at which the meat is hot throughout but still juicy. If the ham is “fresh” (uncured and uncooked), it must reach an internal temperature of 145 degrees Fahrenheit followed by a rest period.
