Cooking a holiday centerpiece or a Sunday dinner doesn’t have to involve hours of hovering over a hot oven. While the traditional method of roasting a ham can take a significant portion of your afternoon, the Instant Pot has revolutionized the process. By using pressure cooking technology, you can achieve a juicy, tender, and flavor-infused ham in a fraction of the time. This guide explores everything you need to know about mastering this dish, from selecting the right cut of meat to nailing the perfect glaze.
Why Use an Instant Pot for Ham
The primary challenge with cooking ham—especially the pre-cooked varieties found in most grocery stores—is preventing it from drying out. Ovens use dry heat, which can quickly turn a succulent ham into something resembling leather if you aren’t careful.
The Instant Pot, however, creates a sealed, high-pressure environment filled with steam. This moisture-rich atmosphere ensures that the ham stays incredibly juicy while heating through evenly. Additionally, because the Instant Pot is an enclosed vessel, it acts like a flavor chamber, forcing the sugars and spices of your glaze deep into the meat.
Choosing the Right Ham for Your Pressure Cooker
Before you start, you need to ensure your ham will actually fit in your device. This is the most common mistake home cooks make.
Size and Weight Considerations
For a standard 6-quart Instant Pot, you should look for a bone-in or boneless ham weighing between 3 and 5 pounds. If you have an 8-quart model, you can often go up to 7 or 8 pounds, depending on the shape. It is highly recommended to choose a spiral-sliced ham. Since it is already cut, the heat and the glaze can penetrate the layers much more effectively than a solid block of meat.
Bone-In vs. Boneless
A bone-in ham generally offers better flavor and a more classic presentation. However, the bone can make the ham bulky and difficult to fit under the lid. If you choose bone-in, make sure the “face” of the ham isn’t so wide that it hits the sides of the inner pot. A boneless ham is much easier to maneuver and slice, making it a great choice for beginners or those with smaller pressure cookers.
Essential Ingredients for a Flavorful Result
While the ham is the star, the liquid and the glaze are what bring the dish to life. You never want to cook a ham in an empty pot; you need at least one cup of liquid to allow the cooker to come to pressure.
The Braising Liquid
Instead of plain water, use liquids that complement the saltiness of the pork. Apple juice, pineapple juice, or even a splash of ginger ale works wonders. The acidity in fruit juices helps tenderize the meat further while adding a subtle sweetness.
The Signature Glaze
A classic ham glaze usually consists of a base and several aromatics. Common ingredients include:
- Brown sugar or honey for sweetness and caramelization.
- Dijon mustard or apple cider vinegar for tang.
- Warm spices like ground cloves, cinnamon, or nutmeg.
- Garlic powder or onion powder for a savory depth.
Step-by-Step Instructions for Instant Pot Ham
Follow these steps to ensure your ham comes out perfectly every single time.
-
Preparing the Ham
Start by removing the ham from its packaging. If it comes with a plastic disc over the bone, be sure to discard it. If your ham is a bit too tall for the lid to close, you can trim a small slice off the bottom to make it sit lower.
Create a “foil sling” by folding a long piece of aluminum foil into a wide strip. Place this under the ham; it will make lifting the heavy, hot meat out of the pot much easier once it is finished cooking.
-
Setting Up the Pot
Place the stainless steel inner pot into the base. Pour in your 1 cup of liquid (juice or water). Place the trivet at the bottom of the pot. Position your ham on the trivet, using your foil sling to guide it.
Rub about half of your glaze over the ham, ensuring some gets between the spiral slices. Save the remaining glaze for the finishing step.
-
Pressure Cooking Times
Secure the lid and set the steam release valve to the “Sealing” position. Set the Instant Pot to Manual or Pressure Cook on High.
For a pre-cooked ham, you generally need about 2 minutes of cook time per pound. For a 5-pound ham, 10 minutes is usually sufficient. Remember, you aren’t “cooking” the meat from raw; you are thoroughly heating it and infusing flavor.
-
The Release and Rest
Once the timer goes off, allow for a Natural Pressure Release for at least 10 to 15 minutes. This prevents the steam from escaping too quickly, which can pull moisture out of the meat. After 15 minutes, flip the valve to “Venting” to release any remaining steam.
Carefully lift the ham out using the foil sling and place it on a baking sheet or serving platter.
-
Achieving the Perfect Crust
While the Instant Pot is great for moisture, it doesn’t provide the crispy, caramelized exterior that many people love. To get that look, you’ll want to finish the ham in the oven or under a broiler.
Brush the remaining glaze over the warm ham. Place it in an oven preheated to 400°F for about 10 minutes, or under the broiler for 3 to 5 minutes. Keep a close watch; the high sugar content in the glaze can go from caramelized to burnt very quickly. You are looking for a bubbly, golden-brown finish.
Tips for Success and Troubleshooting
If your ham feels a little tough, it likely didn’t have enough resting time. Let the meat sit for 10 minutes after the oven stage before carving; this allows the juices to redistribute.
If the lid won’t close because the ham is slightly too big, do not force it. You can wrap the top of the ham tightly in foil and leave the lid slightly ajar if you are using a “slow cook” function, but for pressure cooking, the lid must seal. In this case, your only option is to trim the ham until the lid fits comfortably.
Serving and Leftover Ideas
Once your ham is finished, pour some of the juices from the bottom of the Instant Pot into a small saucepan. Simmer it on the “Sauté” setting with a little cornstarch slurry to create a savory ham gravy to serve on the side.
Leftover ham is incredibly versatile. You can dice it for omelets, toss it into a split pea soup, or make classic ham and cheese sliders. Because the Instant Pot kept the meat so moist, the leftovers will stay fresh and delicious in the refrigerator for up to four days.
FAQs
Can I cook a frozen ham in the Instant Pot?
It is possible to cook a frozen ham, but it is not recommended for the best texture. If you must cook from frozen, you will need to increase the pressure cook time to approximately 5 to 7 minutes per pound. However, the outside may become overcooked before the center is thoroughly heated. It is always better to thaw the ham in the refrigerator for 24 to 48 hours before cooking.
How do I prevent the ham from becoming too salty?
Ham is naturally high in sodium. To balance this, avoid adding any extra salt to your glaze or braising liquid. Using a sweet liquid like pineapple juice or apple juice helps to cut through the saltiness. If you are very sensitive to salt, you can rinse the ham under cold water and pat it dry before putting it in the pot to remove excess surface brine.
What if my Instant Pot displays a Burn notice?
The “Burn” notice usually happens if there isn’t not enough thin liquid at the bottom of the pot or if some of the sugary glaze has dripped down and stuck to the bottom. To avoid this, ensure you have at least 1 cup of juice or water in the bottom and keep the ham elevated on the trivet so it isn’t touching the floor of the inner pot.
Can I use the Instant Pot for a fresh, uncooked ham?
The instructions in this guide are specifically for pre-cooked (city) hams. If you have a “fresh” or raw ham, the cooking time will be significantly longer—usually around 15 to 20 minutes per pound—and you must ensure the internal temperature reaches 145°F followed by a three-minute rest.
How much ham should I buy per person?
A good rule of thumb for a bone-in ham is to plan for about 3/4 pound per person. For a boneless ham, you can plan for about 1/2 pound per person. If you want plenty of leftovers for sandwiches and soups, increase those estimates by about 25 percent.
