Getting Started: Choosing Your Ham

Before we dive into the overnight cooking methods, let's talk about choosing the right ham. There are two main types:

• City Ham: These hams are fully cooked and require only reheating. They're perfect for an overnight cook.
• Country Ham: These hams are not fully cooked and require longer cooking times. They are not ideal for an overnight cook unless you have a very long slow cooking method.

For this guide, we'll focus on city hams, as they're best suited for overnight cooking. Check the package instructions to confirm that your ham is fully cooked.

Method 1: Oven-Baked Overnight Ham

This method is perfect for a consistent and even cook, ideal for larger hams.

Ingredients:

• 1 fully cooked city ham (bone-in or boneless)
• 1 cup water or ham glaze (store-bought or homemade)

Instructions:

1. Preheat: Preheat your oven to 275°F (135°C).
2. Prepare the Ham: Place the ham in a roasting pan. Add 1 cup of water or glaze to the bottom of the pan. This helps keep the ham moist and prevents it from drying out. If using a glaze, reserve some for later.
3. Bake: Bake the ham uncovered for approximately 8-10 hours, or until the internal temperature reaches 140°F (60°C). The cooking time will depend on the size of your ham. Use a meat thermometer to ensure accuracy. A larger ham will require longer cooking time.
4. Glaze (Optional): During the last hour of cooking, you can add your glaze. Baste the ham with the glaze every 15-20 minutes. This will give your ham a beautiful, glossy finish and added flavor.
5. Rest: Once cooked, remove the ham from the oven and let it rest for at least 15-20 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful ham.

Tips for Oven Baking:

• Use a meat thermometer: This is crucial for ensuring the ham is cooked thoroughly and safely.
• Cover loosely with foil: If the ham starts to brown too quickly, loosely tent it with aluminum foil to prevent over-browning.

Method 2: Slow Cooker Overnight Ham

This is a hands-off method perfect for smaller hams and those who prefer a more tender result.

Ingredients:

• 1 fully cooked city ham (bone-in or boneless, smaller size recommended)
• 1 cup water or broth
• ½ cup brown sugar (optional)
• 2 tablespoons Dijon mustard (optional)

Instructions:

1. Prepare the Ham: Place the ham in your slow cooker. Add the water or broth to the bottom of the slow cooker.
2. Season (Optional): If desired, add brown sugar and Dijon mustard for added flavor.
3. Cook: Cook on low for 6-8 hours, or until the internal temperature reaches 140°F (60°C).
4. Rest: Once cooked, remove the ham from the slow cooker and let it rest for at least 15-20 minutes before slicing.

Tips for Slow Cooking:

• Smaller Hams are Best: A larger ham might not cook evenly in a slow cooker.
• Adjust Cooking Time: Cooking time may vary depending on your slow cooker and the size of your ham.

How to Tell When Your Ham is Done

The best way to know your ham is fully cooked is to use a meat thermometer. Insert the thermometer into the thickest part of the ham, avoiding the bone. The internal temperature should reach 140°F (60°C). Never rely solely on cooking time.

Serving Your Overnight Ham

Once rested, slice your ham and serve. Enjoy it as part of a holiday feast or a simple weeknight meal. It's delicious on its own or with sides like mashed potatoes, roasted vegetables, or green bean casserole.
