How To Cook Ham Joint In Slow Cooker On High [GUIDE]

Cooking a ham joint in a slow cooker is one of the most convenient ways to achieve a tender, flavorful meal without spending hours over a hot stove. Unlike traditional oven roasting, the slow cooker allows the ham to cook evenly while soaking up any seasonings or glazes you add, resulting in a moist, succulent centerpiece. Whether you’re preparing for a casual family dinner or a holiday gathering, slow cooking simplifies the process and enhances the natural flavors of the meat. Using the high setting can speed things up compared to a slow simmer, making it a practical option when time is limited, while still delivering that melt-in-your-mouth texture slow cookers are renowned for.

How Long To Cook Ham Joint In Slow Cooker On High

Cooking time is critical to achieving a perfectly cooked ham joint. On the high setting, a general rule of thumb is to cook for approximately 3 to 4 hours per kilogram (2-3 pounds). However, the exact time can vary depending on the size and shape of your ham, whether it is bone-in or boneless, and the type of slow cooker used.

For example:

• A 1 kg (2.2 lbs) boneless ham joint usually takes around 3 hours on high.
• A 2 kg (4.4 lbs) ham joint can require 5-6 hours on high.

It’s important not to rush the process. Even on high, low and steady heat ensures the meat remains tender and juicy rather than dry or rubbery.

How To Tell If It Is Done

The most reliable method to check doneness is using a meat thermometer. Insert it into the thickest part of the ham, avoiding bone if it’s bone-in. The internal temperature should reach at least 60-65°C (140-150°F) for pre-cooked hams, and 70°C (160°F) for uncooked or fresh ham joints.

Other indicators include:

• Texture: The meat should feel tender and slightly springy when pressed.
• Juices: Clear juices indicate that it is properly cooked; pink juices may suggest it needs more time.
• Pull-apart ability: A slow-cooked ham should be easy to cut or pull apart with a fork.

Ingredients Needed

The beauty of slow cooker ham lies in its versatility. A simple set of ingredients can create a deeply flavored dish:

Essential Ingredients

• Ham joint (bone-in or boneless, 1-2 kg)
• 1 cup water, stock, or apple juice (for moisture)
• 2-3 tablespoons brown sugar or honey (optional glaze)
• 1-2 teaspoons mustard or Dijon mustard
• Cloves, whole or ground (optional for added aroma)

Optional Flavor Enhancers

• Pineapple slices or juice for a sweet tang
• Onion, chopped or sliced
• Garlic cloves, smashed
• Fresh herbs such as thyme or rosemary
• Maple syrup or molasses for deeper caramelization

These ingredients work in harmony to infuse the ham with sweet, savory, and aromatic flavors.

How To Cook Ham Joint In Slow Cooker On High

1. Prepare the Ham: If your ham has skin, score it in a crisscross pattern. Stud with cloves if desired.
2. Add Liquid: Pour water, stock, or juice into the slow cooker to ensure the meat remains moist.
3. Mix the Glaze: Combine sugar, mustard, and any optional flavorings. Rub or pour over the ham, making sure it is evenly coated.
4. Cook on High: Place the ham in the slow cooker and cover with the lid. Cook on high for the recommended time based on its weight.
5. Baste Occasionally: If possible, baste the ham once or twice during cooking to intensify flavor and keep the surface moist.
6. Check Doneness: Use a meat thermometer to ensure it reaches the proper internal temperature before serving.

When Things Go Wrong

Even with slow cookers, mishaps can occur:

• Ham is dry: Likely overcooked or insufficient liquid. Ensure a minimal amount of liquid and wrap loosely in foil for moisture retention.
• Flavor too bland: Try adding a more concentrated glaze or additional seasonings mid-cooking.
• Uneven cooking: Ensure the ham fits snugly but not tightly; if too large, cut in half to cook evenly.
• Burned glaze: High sugar content can scorch; add sugar later in cooking or cover ham loosely with foil.

Expert Tips

• Use a pre-cooked ham: Most store-bought hams are already cooked; slow cooking will mainly heat and tenderize while adding flavor.
• Let it rest: After cooking, rest the ham for 10-15 minutes before carving. This allows juices to redistribute.
• Layer flavors: Place onions, garlic, and herbs beneath the ham for deeper infusion.
• Don’t lift the lid frequently: Every lid lift can extend cooking time by 15-20 minutes.

Can I Do This Without A Slow Cooker?

Absolutely. An oven or pressure cooker can be used:

• Oven: Wrap the ham in foil and bake at 160°C (320°F) for approximately 20-25 minutes per 500g (1 lb). Add liquid to the bottom of the pan to maintain moisture.
• Pressure cooker/Instant Pot: Cook on high pressure for 15-20 minutes per 500g (1 lb), with at least 1 cup of liquid for steam. Release pressure naturally for best results.

Reheating Leftovers In Slow Cooker

Reheating ham in the slow cooker preserves moisture and flavor:

1. Slice the ham into portions for even reheating.
2. Place in the slow cooker with a splash of liquid or leftover glaze.
3. Heat on low for 1-2 hours until warmed through, stirring occasionally.

Avoid high heat, which can dry out previously cooked meat.

FAQs

How Long Should I Cook A Ham Joint In A Slow Cooker On High?

Cooking times vary depending on the size of the ham joint. As a general guideline, cook a 1-2 kg ham joint on high for 3 to 4 hours. Larger joints may require 4 to 5 hours. Ensure the internal temperature reaches at least 145°F (63°C) for safe consumption.

Do I Need To Add Liquid When Cooking Ham In A Slow Cooker?

Yes, adding liquid helps keep the ham moist and prevents it from drying out. You can use water, stock, fruit juice, or a mixture of liquids with seasonings or sweeteners like honey or maple syrup.

Should I Cover The Ham Joint With Foil In The Slow Cooker?

No, you do not need to cover the ham with foil inside the slow cooker because the lid of the slow cooker traps moisture, creating a steaming effect. Foil can be used to cover the top of the ham for glazing if desired.

Can I Glaze The Ham While It Cooks In The Slow Cooker?

Yes, you can apply a glaze during the last 30-45 minutes of cooking. Popular glazes include honey, brown sugar, mustard, or fruit preserves. Applying it too early can cause the sugars to burn.

Is It Necessary To Brown The Ham Before Slow Cooking?

Browning is optional. Searing the ham in a pan before slow cooking adds flavor and color to the exterior, but it is not required as slow cooking will cook it thoroughly.

How Do I Prevent The Ham From Drying Out In A Slow Cooker?

To prevent dryness, add sufficient liquid, cook on high for the recommended time, and avoid overcooking. Basting occasionally and using a foil tent for glazing can also help retain moisture.

Can I Add Vegetables To The Slow Cooker With The Ham?

Yes, root vegetables like potatoes, carrots, and onions work well. Place them at the bottom of the slow cooker so they cook evenly while the ham rests on top. Avoid adding delicate vegetables like peas until the last hour.

How Do I Check If The Ham Is Fully Cooked?

Use a meat thermometer to check the internal temperature. The ham is safe to eat when it reaches at least 145°F (63°C) and the juices run clear. For a more tender texture, you can allow it to reach 160-165°F (71-74°C).

Can I Use A Pre-cooked Or Smoked Ham Joint In A Slow Cooker?

Yes, pre-cooked or smoked ham joints can be used. Since they are already cooked, the goal is to heat them thoroughly and infuse flavor. Reduce the cooking time to 2-3 hours on high, depending on size.

How Should I Store Leftover Ham After Slow Cooking?

Allow the ham to cool slightly, then wrap it tightly in foil or store in an airtight container in the refrigerator. Leftover ham can be stored for up to 3-4 days or frozen for 1-2 months for longer storage.
