The holiday season often feels like a high-stakes juggling act. Between timing the side dishes, managing the oven temperature for rolls, and making sure the appetizer tray stays full, the centerpiece protein can become a source of major stress. This is where the slow cooker becomes your most valuable player. While many people think of baking a ham as an oven-only endeavor, learning how to bake a ham in a crock pot is a game-changer that yields incredibly succulent results while freeing up your precious oven space.
Why the Slow Cooker Beats the Oven for Ham
Traditional oven baking can be risky for a pre-cooked ham. Because most hams sold in grocery stores are already smoked or fully cooked, the goal of “baking” is really just reheating it to a safe internal temperature while adding flavor. In a dry oven, it is remarkably easy to end up with a ham that is leathery on the outside and dry on the inside.
The crock pot creates a sealed, humid environment. As the ham heats, the moisture stays trapped inside the ceramic vessel, essentially “basting” the meat in its own juices and whatever glaze you have applied. This method is particularly forgiving for spiral-sliced hams, which are notorious for drying out because the slices allow heat to penetrate the interior too quickly.
Selecting the Right Ham for Your Crock Pot
Before you start, you need to ensure your ham actually fits. Most standard oval-shaped slow cookers (6 to 8 quarts) can accommodate a ham weighing between 7 and 10 pounds.
Bone-In vs. Boneless
A bone-in ham is generally preferred for flavor. The bone helps conduct heat more evenly through the center and adds a depth of savoriness that boneless hams often lack. Plus, you get the added bonus of a ham bone to use for split pea soup or beans later. However, a boneless ham is much easier to fit if you have a smaller slow cooker.
Spiral-Cut vs. Whole
Spiral-cut hams are convenient because they are already sliced to the bone. They take up glaze beautifully because the liquid can seep between the slices. If you choose a whole, non-sliced ham, you will want to score the surface in a diamond pattern to allow the glaze to penetrate.
Size Constraints
If you buy a ham and realize it is just a bit too tall for the lid to close, don’t panic. You can create a “foil tent.” Simply wrap a large piece of heavy-duty aluminum foil over the top of the slow cooker and crimp it tightly around the edges of the ceramic pot to seal in the steam.
Preparing Your Signature Glaze
A great slow cooker ham relies on a balance of sweetness, acidity, and spice. While many hams come with a foil packet of glaze, making your own elevates the dish from “standard” to “spectacular.”
The Sweet Component
Brown sugar is the classic choice because it creates a deep, molasses-like syrup. However, you can also use honey, maple syrup, or even apricot preserves. The sugar is essential because it counteracts the natural saltiness of the cured pork.
The Liquid Base
You need a small amount of liquid in the bottom of the crock pot to prevent scorching and to create steam. Pineapple juice is a traditional favorite because its enzymes help tenderize the meat. Other great options include apple cider, orange juice, or even a splash of ginger ale or Dr. Pepper for a unique southern twist.
The Aromatics
To add complexity, incorporate ground cloves, cinnamon, or dry mustard. If you want a more savory profile, smashed garlic cloves and a few sprigs of fresh rosemary tucked into the pot can work wonders.
Step-by-Step Instructions for Slow Cooker Success
-
Prepare the Ham
Remove the ham from its packaging and discard the plastic disk that often covers the bone end. If you are using a whole ham, score the fat in a 1-inch diamond pattern, being careful not to cut too deep into the meat. -
Layer the Flavors
Place the ham in the slow cooker. If it is a half-ham, place it flat-side down. Rub your brown sugar or glaze mixture all over the surface. If you are using pineapple rings or maraschino cherries, you can pin them to the ham using toothpicks. -
Add the Liquid
Pour your chosen liquid (juice or soda) into the bottom of the pot. Avoid pouring it directly over the ham so you don’t wash off the sugar rub you just applied. -
Set the Time and Temperature
Cover the pot tightly. Set the crock pot to Low. For a 7 to 10 pound ham, you will typically need 4 to 6 hours. While it is tempting to use the High setting to save time, the Low setting is much better for maintaining the integrity of the meat’s texture. -
Baste Regularly
Every hour or so, use a large spoon or a turkey baster to scoop the juices from the bottom of the pot and drizzle them over the top of the ham. This ensures the glaze builds up into a sticky, delicious coating.
Finishing Touches for a Crispy Crust
One drawback of the slow cooker is that it doesn’t provide the “bark” or caramelized crust that some people love. If you want that golden-brown finish, you can perform a quick oven sear at the end.
Carefully remove the ham from the slow cooker and place it on a baking sheet. Brush it with a bit more of the concentrated juices from the pot. Place it under the broiler for 3 to 5 minutes, watching it very closely. The sugars will bubble and brown quickly, providing that professional, oven-baked look.
Serving and Storage Tips
Once the ham reaches an internal temperature of 140 degrees Fahrenheit, it is ready. Let the ham rest for at least 15 to 20 minutes before carving. This allows the juices to redistribute so the meat stays moist on the platter.
Leftover ham can be stored in the refrigerator for up to 4 days or frozen for up to 2 months. The liquid left in the crock pot is “liquid gold“—strain it and save it to use as a base for gravy or to flavor a pot of collard greens.
Frequently Asked Questions
-
Do I need to add water to the bottom of the crock pot?
You should add a small amount of liquid, but it doesn’t have to be water. Using about 1/2 cup to 1 cup of fruit juice, cider, or even a bit of wine adds significantly more flavor than plain water while still providing the necessary moisture to create steam. -
How long does it take to cook a ham per pound in a slow cooker?
Since the ham is already cooked, you are simply warming it. A general rule of thumb is approximately 15 to 20 minutes per pound on the Low setting. Always use a meat thermometer to ensure the thickest part of the ham reaches 140 degrees Fahrenheit. -
Can I cook a frozen ham in the crock pot?
It is not recommended to put a completely frozen ham into a slow cooker. Because the crock pot heats slowly, the meat may spend too much time in the “danger zone” (between 40 degrees Fahrenheit and 140 degrees Fahrenheit) where bacteria can grow. Always thaw your ham in the refrigerator for 24 to 48 hours before cooking. -
Why did my ham turn out salty?
Ham is naturally high in sodium due to the curing process. To mitigate this, ensure you are using a sweet glaze with plenty of brown sugar or honey. You can also soak the ham in cold water for an hour before putting it in the crock pot to draw out some of the excess salt, though this is usually not necessary if you use a flavorful liquid base. -
What if the ham is too big for the lid to fit?
If the bone or the top of the ham sticks out above the rim of the slow cooker, do not try to force the lid. Instead, wrap a double layer of heavy-duty aluminum foil over the top of the slow cooker, creating a dome shape. Seal the edges tightly against the side of the pot to ensure no steam escapes. This effectively extends the height of your cooker.
