A spiral cut ham is often the centerpiece of holiday gatherings, Sunday dinners, and celebratory feasts. Because these hams come pre-sliced and usually pre-cooked, the challenge isn’t really “cooking” the meat, but rather reheating it without turning it into a dry, salty brick. If you have ever wondered how to heat spiral cut ham so that it remains succulent, tender, and flavorful, you have come to the right place. This guide covers every method, tip, and trick to ensure your ham is the star of the show.
Understanding the Spiral Cut Ham
Before you turn on the oven, it is important to understand what you are working with. Most spiral cut hams sold in grocery stores are “city hams,” which means they have been cured in a brine and are fully cooked and smoked. The “spiral cut” refers to the way the ham was sliced in a continuous circle all the way to the bone.
While this makes serving incredibly easy, it also makes the ham vulnerable. Because the meat is already sliced, there is more surface area exposed to the air. If heated improperly, the moisture escapes from between those slices, leaving you with leathery edges. The goal of reheating is to gently raise the internal temperature while locking in as much moisture as possible.
Preparing Your Ham for the Oven
Preparation is the most overlooked step in the reheating process. Taking a cold ham straight from the refrigerator and putting it into a hot oven is a recipe for uneven heating.
Tempering the Meat
Take the ham out of the refrigerator about 1 to 2 hours before you plan to heat it. Allowing it to sit at room temperature for a short period (tempering) helps the heat penetrate the center more efficiently, meaning the outside won’t have to sit in the oven as long.
Inspecting the Packaging
Always check the packaging for a “plastic disk” or “bone guard.” This is often placed over the end of the bone to prevent it from piercing the plastic wrap. If you leave this on during heating, it can melt or create an unpleasant smell.
The Best Way to Heat Spiral Cut Ham: The Oven Method
The oven is the traditional and most reliable method for heating a large ham. The key here is “low and slow.” High temperatures are the enemy of pre-sliced pork.
Step 1: Set the Temperature
Preheat your oven to 275°F or 300°F. While 325°F is common for many roasted meats, a lower temperature is much safer for a spiral cut ham to prevent the edges from curling and drying out.
Step 2: Add Moisture
Place the ham in a heavy roasting pan. To create a steamy environment, add about 1/2 cup of water, apple juice, or white wine to the bottom of the pan. This liquid will evaporate during the heating process, keeping the air inside the pan humid.
Step 3: The Tight Seal
This is the most critical step. Wrap the ham tightly with heavy-duty aluminum foil. If your roasting pan has a very tight-fitting lid, you can use that, but foil is usually better because you can mold it directly around the ham. You want to ensure no steam can escape.
Step 4: Position the Ham
Place the ham cut-side down in the pan. This protects the majority of the slices from direct heat and allows the natural juices to move downward into the thickest part of the meat.
Step 5: Heating Time
A general rule of thumb is to heat the ham for 10 to 12 minutes per pound. For a standard 8-pound ham, this will take approximately 1.5 to 2 hours. You are aiming for an internal temperature of 140°F. Since the ham is already cooked, you aren’t looking for “doneness” in a food safety sense, but rather a pleasant serving temperature.
Using a Slow Cooker for Smaller Hams
If you have a smaller spiral cut ham (usually under 8 pounds) and want to save oven space for side dishes, the slow cooker is an excellent alternative. It is essentially a self-basting environment that excels at keeping meat moist.
To use this method, place the ham in the crock. If it is too tall for the lid to close, you can create a “tent” out of aluminum foil to seal the top. Add a splash of liquid (liquid gold, also known as pineapple juice, works wonders here). Set the slow cooker to Low and heat for 3 to 4 hours. Avoid using the High setting, as it can toughen the delicate slices.
How to Apply a Glaze Without Drying Out the Ham
Most spiral hams come with a glaze packet, or you might choose to make your own using brown sugar, honey, mustard, and spices. The mistake many people make is applying the glaze at the beginning of the heating process. Because glazes are high in sugar, they will burn if left in the oven for two hours.
The right way to glaze is to wait until the last 20 to 30 minutes of heating. Remove the ham from the oven, increase the oven temperature to 400°F, and carefully peel back the foil. Brush the glaze generously over the surface and between the slices. Put the ham back in the oven, uncovered, for 10 to 15 minutes until the glaze is bubbly and caramelized.
Serving and Carving Tips
Once your ham has reached 140°F, remove it from the oven. Do not cut into it immediately. Let the ham rest, still covered in foil, for at least 15 to 20 minutes. This allows the juices to redistribute so they don’t all run out onto the cutting board.
Because the ham is already spiral-cut, serving is simple. Use a sharp knife to cut along the natural fat lines or around the center bone. The slices should fall away effortlessly.
Common Mistakes to Avoid
- Overheating: If you take the ham to 160°F or higher, it will become crumbly and dry. Remember, you are just warming it.
- Skipping the Foil: An uncovered spiral ham in a dry oven will lose its moisture in minutes.
- Too Much Liquid: While you want some moisture in the pan, don’t submerge the ham. You are steaming it, not boiling it.
- Forgetting the Thermometer: Visual cues are hard with ham. Use a meat thermometer to check the thickest part of the meat (without touching the bone) to get an accurate reading.
Frequently Asked Questions
Can I eat spiral cut ham cold?
Yes, you can absolutely eat spiral cut ham cold. Since it is fully cooked and cured, it is safe to eat straight from the refrigerator. Many people prefer cold ham for sandwiches or salads. If you choose to serve it cold for a dinner party, just make sure to take it out of the fridge about 30 minutes before serving so it isn’t unpleasantly chilled.
How do I keep the ham from getting too salty?
Spiral hams are naturally salty due to the curing process. To balance this, use a sweet glaze containing honey, maple syrup, or brown sugar. If you find your hams are consistently too salty, you can rinse the ham under cold water before heating it to remove surface salt, though this is rarely necessary if you use a sweet glaze.
How long does leftover spiral ham last in the fridge?
Leftover ham is good for 3 to 5 days when stored in an airtight container in the refrigerator. If you can’t finish it in that time, ham freezes remarkably well. Wrap individual slices or the remaining bone-in chunk tightly in plastic wrap and then foil, and it will stay fresh in the freezer for up to 2 months.
Can I reheat a spiral ham in the microwave?
It is not recommended to reheat a whole spiral ham in the microwave. The microwave heats unevenly and will likely result in some parts being rubbery and others remaining cold. However, the microwave is perfectly fine for reheating individual slices. Place a slice on a microwave-safe plate, cover with a damp paper towel, and heat in 30-second intervals.
What should I do with the leftover ham bone?
Never throw away the bone! The bone from a spiral cut ham is packed with smoky flavor. It is the perfect base for soups, such as split pea soup, navy bean soup, or ham and potato chowder. You can toss the bone into a freezer bag and save it for a rainy day when you are ready to make a slow-simmered broth.
