A precooked ham in a slow cooker just needs gentle warming with a glaze, as it only requires reheating, not cooking. This method is perfect for freeing up oven space during holidays or busy weeknights. You can achieve a juicy, flavorful ham with minimal effort by following a few simple steps.
The slow cooker locks in moisture, preventing the ham from drying out. Unlike an oven, it provides a consistent, low heat that warms the meat evenly. Plus, the glaze caramelizes beautifully over several hours.
Before you start, check the ham’s weight and packaging. Most spiral-sliced or bone-in hams are fully cooked. You just need to heat them to an internal temperature of 140°F.
Why Use A Slow Cooker For Precooked Ham
Using a slow cooker is one of the easiest ways to reheat a precooked ham. It keeps the meat tender and moist without constant monitoring. You can set it and forget it, which is ideal for entertaining.
The slow cooker also infuses the ham with flavors from your glaze and any added liquids. The low, slow heat helps the glaze penetrate the surface layers. This results in a more flavorful ham than simply warming it in the microwave.
Another advantage is the space saving. Your oven stays free for side dishes like casseroles or roasted vegetables. This makes holiday meal prep much smoother and less stressful.
How To Cook A Precooked Ham In Slow Cooker
Here is the complete process for achieving a perfect ham. Follow these steps carefully for the best results. You will need a slow cooker large enough to hold the ham comfortably.
Choose The Right Ham
Select a fully cooked ham that fits your slow cooker. Spiral-sliced hams work well because they are easy to serve. Bone-in hams add extra flavor but take up more space.
- Check the label for “fully cooked” or “ready to eat.”
- Remove any plastic packaging or netting before cooking.
- If the ham is frozen, thaw it completely in the refrigerator first.
Prepare The Glaze
A simple glaze enhances the ham’s natural sweetness. Common ingredients include brown sugar, honey, mustard, and pineapple juice. You can also use maple syrup or apricot preserves.
Mix your glaze ingredients in a small bowl. Aim for a thick, syrupy consistency that will coat the ham. You can adjust sweetness or tanginess to your taste.
Place Ham In Slow Cooker
Lightly grease the bottom of the slow cooker to prevent sticking. Place the ham cut-side down if it is spiral-sliced. This helps the slices stay together during reheating.
Pour a small amount of liquid, like apple juice or chicken broth, into the bottom. This creates steam and prevents the ham from drying out. About half a cup is usually enough.
Apply The Glaze
Brush the glaze generously over the entire surface of the ham. Use a pastry brush or spoon to cover all exposed areas. Pay extra attention to the cut surfaces for maximum flavor.
Reserve some glaze to brush on later during the cooking process. This adds layers of flavor and helps build a nice crust.
Set The Temperature And Time
Cook the ham on low heat for 4 to 6 hours, depending on its size. A 5-pound ham typically takes about 4 hours on low. Larger hams may need up to 6 hours.
Avoid cooking on high heat, as it can dry out the meat. The goal is gentle reheating, not cooking from raw. Use a meat thermometer to check the internal temperature reaches 140°F.
Baste Occasionally
Every hour or so, open the lid and baste the ham with the juices from the bottom. This keeps the surface moist and helps the glaze set. If you reserved extra glaze, apply it during the last hour.
Basting also distributes flavor evenly across the ham. It is a simple step that makes a big difference in taste and texture.
Rest And Serve
Once the ham reaches 140°F, turn off the slow cooker. Let the ham rest for 10 to 15 minutes before slicing. This allows the juices to redistribute, making the meat more tender.
Transfer the ham to a cutting board and slice against the grain. Serve with the remaining juices from the slow cooker as a sauce. You can also thicken the juices with cornstarch for a gravy.
Tips For Best Results
These tips will help you avoid common mistakes. They ensure your ham turns out juicy and flavorful every time.
Don’t Overcook
Since the ham is already cooked, you only need to warm it. Overcooking can make the meat dry and tough. Stick to the recommended time and temperature.
Use a meat thermometer to be precise. Insert it into the thickest part of the ham, avoiding the bone. Remove the ham from heat as soon as it hits 140°F.
Add Aromatics
Enhance the flavor by adding aromatics to the slow cooker. Whole cloves, cinnamon sticks, or bay leaves work well. You can also add sliced onions or garlic cloves.
These ingredients infuse the ham with subtle notes during cooking. They complement the sweetness of the glaze without overpowering it.
Use A Liner
Slow cooker liners make cleanup much easier. The glaze and juices can stick to the pot, creating a mess. A liner prevents this and saves you scrubbing time.
Simply place the liner in the slow cooker before adding the ham. After cooking, lift it out and discard it. This is especially helpful for large holiday meals.
Glaze Variations To Try
Experiment with different glaze combinations to suit your taste. Here are three popular options that work well with a slow cooker ham.
Brown Sugar And Mustard
Mix 1 cup brown sugar, 2 tablespoons Dijon mustard, and 2 tablespoons apple cider vinegar. This classic glaze balances sweet and tangy flavors. It caramelizes nicely during the long cook time.
Honey And Pineapple
Combine 1/2 cup honey, 1/2 cup pineapple juice, and 1 teaspoon ground ginger. This tropical glaze adds brightness and pairs well with ham. The pineapple juice also helps tenderize the meat slightly.
Maple And Bourbon
Stir together 1/2 cup maple syrup, 2 tablespoons bourbon, and 1 teaspoon black pepper. This adult-friendly glaze offers a rich, smoky sweetness. The bourbon adds depth without being overpowering.
Common Mistakes To Avoid
Even with a simple method, a few errors can ruin your ham. Here are mistakes to watch out for.
Using Too Much Liquid
Adding too much liquid can make the ham soggy. The ham releases its own juices as it heats. Stick to a small amount of liquid, like half a cup, to create steam.
If you want more sauce, add it later after cooking. You can simmer the juices on the stovetop to reduce and thicken them.
Skipping The Glaze
Without a glaze, the ham can taste plain and dry. The glaze adds flavor and helps lock in moisture. Even a simple brown sugar rub makes a difference.
Apply the glaze at the start and again during cooking. This ensures the ham is well-coated and flavorful throughout.
Opening The Lid Too Often
Every time you open the lid, heat escapes and cooking time increases. Resist the urge to check on the ham frequently. Stick to basting once per hour to maintain temperature.
If you need to check the temperature, do it quickly. Close the lid immediately after to keep the heat inside.
