Cooking a ham is often associated with big holiday productions, crowded ovens, and the constant stress of monitoring a meat thermometer while trying to mash potatoes and toss a salad. However, the secret to a stress-free, incredibly juicy centerpiece lies in that trusty appliance sitting on your kitchen counter: the slow cooker. When you learn how to cook a ham slow cooker style, you reclaim your oven space and ensure the meat stays tender through gentle, consistent heat.
This method is particularly effective because hams are typically sold precooked or smoked. Your primary goal isn’t to “cook” the meat in the traditional sense, but to reheat it thoroughly while infusing it with moisture and flavor. The sealed environment of a slow cooker prevents the meat from drying out, which is the most common pitfall of oven-roasting.
Selecting the Right Ham for Your Slow Cooker
Before you plug in your appliance, you need to choose the right cut of meat. Not every ham is built for every crockpot.
Size and Shape Considerations
The most critical factor is whether the ham will actually fit. Most standard large slow cookers (6 to 7 quarts) can accommodate a 7 to 9-pound ham. If you buy a bone-in half ham, look for one with a flatter end so it can sit securely. If the lid won’t close completely because the bone is sticking out, you can create a “tent” using heavy-duty aluminum foil to seal the top, though a proper fit is always preferred for heat retention.
Spiral Cut vs. Whole Ham
Spiral-cut hams are incredibly convenient because they are pre-sliced. This allows the glaze to seep deep into the layers of the meat. However, they are more prone to drying out if cooked too long. A whole (un-sliced) ham takes a bit more effort to carve but retains its natural juices much better during the long heating process.
Bone-In vs. Boneless
A bone-in ham generally offers superior flavor and a more classic presentation. Plus, you get the added bonus of a ham bone to use for soups or beans later. Boneless hams are easier to fit into smaller slow cookers and are a breeze to slice, making them ideal for casual family dinners or sandwiches.
Essential Ingredients for a Flavorful Glaze
While ham is naturally salty and savory, a good glaze provides the necessary balance of sweetness and acidity. You don’t need a long list of expensive ingredients to make a professional-quality glaze at home.
The Sweet Base
Most successful ham recipes rely on a sugar component that caramelizes as it heats. Brown sugar is the gold standard, offering a deep, molasses-like sweetness. Honey, maple syrup, or even apricot preserves are excellent alternatives that provide a sticky, glossy finish.
Acidic Balancers
To cut through the richness of the pork, you need acid. Pineapple juice is a classic choice, as the enzymes also help tenderize the meat. Apple cider, orange juice, or a splash of apple cider vinegar can also provide that bright contrast.
Aromatic Spices
Don’t overlook the power of spices. Ground cloves, cinnamon, and nutmeg add a warm, autumnal profile. For those who prefer a bit of a kick, a tablespoon of Dijon mustard or a pinch of red pepper flakes can add sophisticated depth to the glaze.
Step-by-Step Instructions for the Perfect Slow Cooker Ham
Following a specific process ensures that your ham is heated evenly without becoming mushy or tough.
Preparation and Placement
Start by removing all packaging, including the plastic disc that often covers the bone end. If you are using a whole ham, you may want to score the surface in a diamond pattern about 1/2 inch deep. This allows the glaze to penetrate and creates a beautiful visual effect.
Place the ham in the slow cooker. If it’s a half-ham, place it flat-side down. This stabilizes the meat and keeps the largest surface area in contact with the juices at the bottom.
Applying the Flavors
Rub your dry ingredients (like brown sugar and spices) directly onto the surface of the meat. Pour your liquid components (like pineapple juice or cider) around the base of the ham rather than directly over the top to avoid washing off the sugar rub. If you are using a spiral-cut ham, gently fan the slices to let some of the juice get between them.
Setting the Time and Temperature
The golden rule for slow cooker ham is “low and slow.” Set your slow cooker to the Low setting. A 7 to 9-pound ham typically requires 4 to 6 hours on Low. Cooking on High is generally discouraged as it can toughen the outer layers of the meat before the center is warm. Your goal is an internal temperature of 140 degrees Fahrenheit.
Tips for the Best Texture and Presentation
Even with the simplicity of a slow cooker, a few professional tips can elevate your meal from good to gourmet.
The Basting Technique
About once every hour, open the lid quickly and spoon the juices from the bottom of the pot over the top of the ham. This builds up layers of flavor and keeps the exterior moist. Do this quickly to prevent too much heat from escaping.
The Optional Broil
While the slow cooker creates incredibly tender meat, it doesn’t provide the crispy, charred edges that some people love. If you want a caramelized crust, carefully remove the ham from the slow cooker 15 minutes before serving. Place it on a baking sheet, brush on some extra glaze from the pot, and pop it under your oven broiler for 3 to 5 minutes until it bubbles and browns.
The Importance of Resting
Just like a steak or a turkey, ham needs to rest. Once you remove it from the heat, transfer it to a cutting board and tent it loosely with foil for 15 to 20 minutes. This allows the juices to redistribute throughout the meat, ensuring every slice is moist.
Creative Ways to Use Leftover Ham
One of the best parts of cooking a large ham is the abundance of leftovers. Because the slow cooker method keeps the meat so juicy, the leftovers stay fresh longer than oven-dried meat.
Breakfast and Brunch
Dice the leftover ham and toss it into a morning omelet, frittata, or breakfast burrito. It also makes a fantastic topping for “Eggs Benedict” or can be fried up as a side to pancakes.
Hearty Soups and Stews
Don’t throw away that bone! Simmer the ham bone with dried split peas or navy beans, onions, carrots, and celery for a classic, comforting soup. The marrow and remaining meat bits will infuse the broth with an incredible smokiness.
Sandwiches and Salads
Thinly sliced cold ham is perfect for sliders with melted Swiss cheese and poppy seed dressing. You can also dice it into a cold pasta salad or a chef’s salad for a quick and protein-packed lunch.
Common Mistakes to Avoid
To ensure your meal is a success, steer clear of these frequent errors.
Adding Too Much Liquid
Unlike a pot roast, ham does not need to be submerged. It releases its own juices as it warms. Adding too much water or juice can dilute the flavor and result in a “boiled” texture rather than a roasted one. A cup of liquid at the bottom is usually more than enough.
Overcooking
Because the ham is already cooked, you are only reheating it. Leaving it in the slow cooker for 8 or 10 hours will cause the fibers to break down too much, resulting in a mealy or mushy texture. Start checking the temperature around the 4-hour mark.
Forgetting to Glaze
The natural saltiness of ham needs a counterpoint. If you skip the glaze, the meat can taste one-dimensional. Even a simple rub of brown sugar makes a world of difference in the final flavor profile.
Frequently Asked Questions
-
Can I cook a frozen ham in the slow cooker?
It is not recommended to put a completely frozen ham directly into a slow cooker. Because slow cookers heat up gradually, the meat may spend too much time in the “danger zone” (between 40 degrees Fahrenheit and 140 degrees Fahrenheit) where bacteria can grow rapidly. It is best to thaw your ham completely in the refrigerator for 24 to 48 hours before cooking.
-
How much ham should I buy per person?
A good rule of thumb is to allow for 3/4 pound per person for a bone-in ham and 1/2 pound per person for a boneless ham. This usually leaves enough for a few leftovers without being overwhelmed by pork for a week.
-
Do I need to add water to the bottom of the slow cooker?
You should add a small amount of liquid to prevent the bottom from scorching and to create steam, but you don’t need much. Use about 1/2 cup to 1 cup of liquid, such as pineapple juice, apple juice, or even ginger ale, to provide moisture and flavor.
-
My ham is too big for the lid to close, what do I do?
If the ham peaks out over the rim of the slow cooker, do not force the lid. Instead, take a large piece of heavy-duty aluminum foil and wrap it tightly over the top of the slow cooker, crimping it around the edges to create a seal. Then, place the lid on top of the foil to help weigh it down. This keeps the steam and heat trapped inside effectively.
-
Is it better to cook ham on Low or High in a slow cooker?
Low is almost always better for ham. High heat can cause the exterior of the ham to become tough and dry before the heat has time to penetrate to the bone. Cooking on Low for a longer period ensures a more uniform temperature and a more tender result.
