The spiral-cut ham is the undisputed king of holiday dinner tables. Whether it is Easter, Thanksgiving, or a cozy Christmas gathering, that beautiful glazed centerpiece is often the star of the show. However, the biggest challenge with a spiral ham is its tendency to dry out. Since these hams are typically sold pre-cooked and pre-sliced, you aren’t really “cooking” the meat so much as you are reheating it to a safe, delicious temperature.
Using a slow cooker is the secret weapon for achieving a juicy, flavorful result. The enclosed environment of a crock pot traps moisture much more effectively than a standard oven, which can act like a giant dehydrator. If you have been wondering exactly how long to cook spiral ham in crock pot setups of various sizes, this guide will walk you through the timing, temperatures, and techniques to ensure your next meal is a resounding success.
Why the Slow Cooker is Superior for Spiral Ham
When you bake a ham in the oven, you are battling dry air. Even when covered in foil, the high heat can cause the thin slices of a spiral ham to curl and lose their moisture. In contrast, a slow cooker creates a gentle, humid environment. As the ham warms, any juices or glazes you add circulate as steam, basting the meat from the inside out.
Furthermore, using a crock pot frees up precious oven space for side dishes like roasted vegetables, rolls, or casseroles. It is a set-it-and-forget-it method that reduces holiday stress while delivering a superior texture.
How Long to Cook Spiral Ham in Crock Pot: The Basic Timeline
The most critical factor in your timing is the size of the ham and whether you are using the “Low” or “High” setting. Because spiral hams are already fully cooked, your goal is to reach an internal temperature of 140 degrees Fahrenheit.
Cooking on the Low Setting
For the best results, most experts recommend the low setting. This allows the heat to penetrate the bone and the center of the ham without overcooking the outer edges.
- Small Ham (4 to 6 pounds): 2.5 to 3.5 hours.
- Average Ham (7 to 8 pounds): 4 to 5 hours.
- Large Ham (9 to 10 pounds): 5 to 6 hours.
Cooking on the High Setting
If you are short on time, you can use the high setting, but you must monitor it closely to prevent the edges from becoming tough.
- Small Ham (4 to 6 pounds): 1.5 to 2 hours.
- Average Ham (7 to 8 pounds): 2.5 to 3 hours.
- Large Ham (9 to 10 pounds): 3.5 to 4 hours.
Always remember that these times are estimates. The actual duration depends on the shape of your ham and the specific heating efficiency of your slow cooker model.
Choosing the Right Size Ham for Your Slow Cooker
Before you head to the grocery store, you need to know the capacity of your crock pot. A standard 6-quart slow cooker can usually accommodate an 8-pound spiral ham, but the shape matters.
If the ham is too tall and the lid won’t close, you have a few options. You can trim a bit off the bottom of the ham to make it fit, or you can create a “foil tent.” To do this, wrap heavy-duty aluminum foil over the top of the slow cooker and crimp it tightly around the edges to seal in the steam. This mimics the lid and allows you to cook a larger ham than your pot would normally allow.
Essential Ingredients for a Juicy Slow Cooker Ham
While you can technically put a ham in the pot by itself, adding a liquid base and a sweetener will transform the dish. Here are the components of a perfect slow cooker ham:
The Liquid Base
You need about half a cup to a full cup of liquid at the bottom of the pot to prevent scorching and create steam. Excellent choices include:
- Apple cider or apple juice
- Pineapple juice
- Orange juice
- Ginger ale or cola
- Water (if you want the natural ham flavor to shine)
The Glaze Components
A spiral ham often comes with a glaze packet, but making your own is simple and tastes much better. Common ingredients include brown sugar, honey, maple syrup, Dijon mustard, and spices like cloves, cinnamon, or nutmeg.
Step-by-Step Instructions for Slow Cooking Your Ham
-
Preparation
Start by removing the ham from its packaging. Be sure to look for the plastic disk that is often attached to the bone on the underside of the ham and discard it.
-
Placing the Ham
Place the ham in the crock pot with the flat side (the cut side) facing down. This helps keep the slices together and allows the juices to pool around the meat. If the ham is too wide, you may need to tilt it slightly.
-
Adding Flavor
Pour your chosen liquid into the bottom of the pot. Rub your brown sugar or glaze mixture all over the outside of the ham, trying to get some between the slices if possible.
-
The Cooking Process
Cover the pot and set it to low. About an hour before the ham is finished, you can baste it with the juices from the bottom of the pot. If you are using a thick glaze, apply it during the final 30 to 45 minutes of cooking to prevent it from burning or becoming too runny.
-
Checking for Doneness
Use a meat thermometer to check the internal temperature. You are looking for 140 degrees Fahrenheit. Insert the thermometer into the thickest part of the meat, making sure not to touch the bone, as the bone conducts heat differently and will give you an inaccurate reading.
Tips for Preventing a Dry Spiral Ham
Even with the slow cooker, there are ways to ensure maximum moisture. One tip is to avoid lifting the lid. Every time you open the slow cooker, you release the steam and heat, which can add 15 to 20 minutes to your cooking time and dry out the meat.
Another tip is to rest the ham. 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 15 to 20 minutes. This allows the juices to redistribute throughout the meat so they don’t run out the moment you start serving.
Creative Uses for Leftover Spiral Ham
One of the best parts of cooking a large ham is the leftovers. Since the slow cooker keeps the meat so tender, the leftovers remain high quality for several days.
- Breakfast: Dice the ham and add it to omelets, frittatas, or breakfast burritos.
- Lunch: Thin slices are perfect for classic ham and cheese sliders or a hearty split pea soup.
- Dinner: Use the ham bone to flavor a pot of beans or a slow-cooked vegetable soup. The residual meat on the bone adds incredible depth to broths.
Frequently Asked Questions
Can I put a frozen spiral ham in the slow cooker?
It is highly recommended that you thaw your ham completely in the refrigerator before putting it in the crock pot. Cooking a frozen ham can result in uneven heating, where the outside becomes overcooked and dry while the center remains cold. Additionally, starting with frozen meat keeps the ham in the “danger zone” for bacterial growth for too long.
How much ham should I buy per person?
When buying a bone-in spiral ham, a good rule of thumb is to plan for about 3/4 pound to 1 pound of meat per person. This accounts for the weight of the bone and ensures you have enough for everyone to have a generous serving plus some leftovers.
Do I need to add water to the bottom of the crock pot?
You should always add at least a small amount of liquid. While the ham will release some juices as it warms, adding half a cup of juice, broth, or water creates the necessary steam to keep the spiral slices moist and prevents the bottom of the ham from sticking to the pot.
What temperature should the ham reach before serving?
Since spiral hams are pre-cooked, you are reheating them to a safe internal temperature of 140 degrees Fahrenheit. If you happen to buy a “fresh” ham that is not pre-cooked, it must reach an internal temperature of 145 degrees Fahrenheit followed by a three-minute rest.
Can I glaze the ham at the beginning of the cooking process?
You can apply a dry rub or a thin liquid at the beginning, but thick, sugary glazes are best applied during the last 30 to 45 minutes of cooking. If sugar-heavy glazes sit in the slow cooker for five hours, they can sometimes break down or develop a slightly burnt flavor. Applying it at the end and basting it once or twice ensures a glossy, delicious finish.
