Cooking a centerpiece meal shouldn’t feel like a high-stakes engineering project. While the oven is the traditional go-to for holiday hams, the slow cooker is the secret weapon of savvy home cooks everywhere. It frees up precious oven space, prevents the meat from drying out, and allows flavors to penetrate deeply into every slice. If you have ever struggled with a chalky, overcooked spiral ham, switching to the crockpot method will be a revelation. This guide explores every nuance of preparing a succulent, flavorful ham using your slow cooker, ensuring your next dinner is both effortless and impressive.
Choosing the Right Ham for Your Slow Cooker
Before you even plug in your appliance, you need to select the right cut of meat. Not all hams are created equal, and some are better suited for the low-and-slow environment than others.
Bone-In vs. Boneless
A bone-in ham is generally the superior choice for flavor and moisture. The bone acts as a conductor of heat and adds a richness to the meat that boneless varieties often lack. However, the biggest challenge with a bone-in ham is fit. You must ensure the ham can actually fit inside your slow cooker. If you choose a boneless ham, it is much easier to wedge into the pot, but you may need to be more vigilant about cook times to prevent it from becoming tough.
Spiral Sliced vs. Whole
Spiral-sliced hams are incredibly convenient because the work of carving is already done for you. The downside is that the pre-cut slices are more susceptible to drying out. If you use a spiral ham, you must use plenty of liquid and keep the lid tightly sealed. A whole, unsliced ham (often called a “butt” or “shank” portion) stays much juicier but requires a bit of elbow grease with a carving knife before serving.
Size Matters
Most standard slow cookers are 6 to 7 quarts. For a cooker of this size, a ham weighing between 6 and 8 pounds is usually the sweet spot. If you buy a ham that is too large, the lid won’t close, which is a deal-breaker for slow cooking. If you find yourself with a ham that is just an inch too tall, you can wrap the top tightly with a double layer of heavy-duty aluminum foil to create a “tent” that seals in the steam.
Preparing Your Ham for the Pot
Once you have your ham, a little preparation goes a long way. If your ham comes with a plastic “button” on the bone, make sure to remove it. If it’s a whole ham (not spiral sliced), you can use a sharp knife to score the fat in a diamond pattern. This isn’t just for aesthetics; it allows your glaze to seep down into the meat rather than just sliding off the surface.
If you find that your ham is slightly too large for the pot, don’t be afraid to trim a small slice off the bottom or the side. You can save these scraps for omelets or pea soup later. The goal is to get the ham settled comfortably so that the heat can circulate.
The Importance of Liquid and Flavor Bases
You should never cook a ham in a slow cooker completely dry. While the ham will release some juices, a starting liquid helps create steam, which is what keeps the meat tender.
Common liquid bases include:
- Apple juice or cider for a crisp, autumnal sweetness.
- Pineapple juice for a tropical, acidic brightness that helps tenderize.
- Chicken broth for a more savory, less sweet profile.
- Ginger ale or cola for a classic Southern-style ham with a caramelized finish.
Aim for about 1/2 cup to 1 cup of liquid at the bottom of the pot. You don’t want to submerge the ham; you just want to create a humid environment.
Crafting the Perfect Glaze
The glaze is where you can truly customize the flavor of your meal. Most store-bought hams come with a glaze packet, but making your own is simple and significantly better.
A classic brown sugar glaze is a crowd-pleaser. Mix 1 cup of brown sugar with 2 tablespoons of Dijon mustard and 1 teaspoon of ground cloves or cinnamon. For something stickier, incorporate honey or maple syrup. If you prefer a savory edge, add a splash of balsamic vinegar or a pinch of black pepper.
Apply about half of your glaze at the beginning of the cooking process. Save the remaining half for the final 30 to 45 minutes of cooking to ensure a thick, tacky coating that hasn’t been washed away by the steam.
Timing and Temperature Settings
Since most hams sold in grocery stores are already fully cooked (often labeled “city hams”), your goal in the slow cooker is not to “cook” the meat in the traditional sense, but to reheat it thoroughly without losing moisture.
For a standard 6 to 8-pound ham, set your slow cooker to Low. Cooking on High is generally discouraged for ham as it can cause the exterior slices to become rubbery before the center is warm.
On the Low setting, plan for about 4 to 6 hours. The internal temperature should reach 140 degrees Fahrenheit. If you are using a raw ham (a “country ham” or a “fresh ham”), the process is entirely different and requires much longer cook times and higher internal temperatures, usually reaching 160 degrees Fahrenheit, but for the standard holiday ham, 140 degrees Fahrenheit is the magic number for food safety and peak texture.
Tips for the Best Results
To elevate your ham from “good” to “unforgettable,” keep these tips in mind:
-
Avoid Peeking: Every time you lift the lid of your slow cooker, you release a significant amount of heat and steam. This can add 15 to 20 minutes to your total cook time and dry out the meat. Only open the lid when it is time to apply the final layer of glaze.
-
The Foil Hack: If your lid doesn’t fit perfectly because the bone is sticking out, use heavy-duty foil to create a dome. Ensure the edges are crimped tightly around the rim of the slow cooker to prevent steam from escaping.
-
Resting is Mandatory: Once the ham reaches 140 degrees Fahrenheit, remove it from the slow cooker and place it on a carving board. Tent it loosely with foil and let it rest for at least 15 to 20 minutes. This allows the juices to redistribute. If you cut into it immediately, the moisture will run out, leaving you with dry meat.
Serving and Leftover Ideas
Once rested, carve the ham against the grain. If you used a spiral-sliced ham, simply cut along the bone to release the slices. Arrange them on a platter and spoon some of the juices from the bottom of the slow cooker over the top.
The beauty of a large ham is the leftovers. The bone is a goldmine of flavor for soups, stews, and beans. The meat itself can be used for sandwiches, diced into breakfast hashes, or tossed into a creamy pasta carbonara.
FAQs
Can I cook a frozen ham in the slow cooker?
It is highly recommended that you thaw your ham completely in the refrigerator before putting it in the slow cooker. Placing a large, frozen block of meat in a slow cooker can keep the meat in the “danger zone” (between 40 degrees Fahrenheit and 140 degrees Fahrenheit) for too long, which increases the risk of bacterial growth. Thawing ensures even heating and better texture.
How do I prevent a spiral ham from drying out?
Spiral hams are prone to drying because the pre-cut slices allow moisture to escape easily. To prevent this, cook the ham cut-side down in the slow cooker. This keeps the slices pressed together. Additionally, ensure you have enough liquid in the bottom of the pot and consider basting the ham with its juices halfway through the cooking process.
Is it better to cook ham on High or Low?
Low is almost always better for ham. Slow and steady heat allows the ham to warm through to the center without overcooking the delicate outer layers. Cooking on High often results in a ham that is dry on the outside while still cold near the bone.
What should I do with the liquid left in the pot?
The liquid left in the slow cooker is packed with flavor. You can strain it and simmer it in a saucepan on the stove to reduce it into a thick syrupy glaze or a savory au jus. If it is too salty, you can dilute it with a little water or unsalted broth before serving it alongside the meat.
How long can I keep cooked ham in the refrigerator?
Once cooked, your ham will stay fresh in the refrigerator for 3 to 4 days if stored in an airtight container. If you have more leftovers than you can eat in that timeframe, ham freezes exceptionally well. Wrap it tightly in plastic wrap and then foil, and it will last for up to 2 months in the freezer.
