How To Cook A Fully Cooked Ham In Crock Pot

A crock pot makes reheating a fully cooked ham simple, though you still need to watch internal temperature and timing. If you want to know how to cook a fully cooked ham in crock pot without drying it out, the method is mostly about low heat and a little liquid.

This guide walks you through prep, cook times, and the exact temperature you need to hit. You can have a warm, sliceable ham ready for dinner with very little hands-on work.

Why Use A Crock Pot For A Fully Cooked Ham

A fully cooked ham is already safe to eat cold. Your job is really just reheating it gently and adding flavor.

A slow cooker is perfect for that because it holds steady low heat. The ham stays moist instead of drying out in a hot oven.

  • No babysitting or basting every 20 minutes
  • Frees up your oven for side dishes
  • Works with bone-in, boneless, spiral, and half hams
  • Keeps the meat tender and easy to slice

The one catch is size. A ham that is too big for your crock pot wont cook evenly. Make sure the lid sits flat and closes all the way.

How To Cook A Fully Cooked Ham In Crock Pot

Follow these steps in order. The whole process is short on prep and long on waiting, which is the point.

Step 1: Choose The Right Ham And Crock Pot Size

Most slow cookers hold a 4 to 7 pound ham. If yours is smaller, buy a smaller ham or cut it into two pieces.

Spiral sliced hams work well here. The slices soak up the glaze and heat through fast.

Step 2: Prep The Crock Pot

Lightly grease the inside with cooking spray or a little oil. This keeps the bottom from sticking and makes cleanup easier.

If you have a crock pot liner, use it. Its a small thing that saves scrubbing later.

Step 3: Add Liquid To The Bottom

Pour about 1/2 to 1 cup of liquid into the pot before the ham goes in. Good options include:

  • Water or chicken broth
  • Apple juice or pineapple juice
  • A mix of water and brown sugar

The liquid creates steam, and steam is what keeps the ham moist. Dont skip it.

Step 4: Place The Ham In The Pot

Set the ham flat side down. If it has a bone, the bone can face any direction as long as the lid fits.

For a spiral ham, let the slices fall naturally. Dont pack them tight.

Step 5: Add Your Glaze Or Toppings

You can brush on a glaze now or halfway through. Simple options that work well:

  • Honey and mustard
  • Brown sugar and pineapple juice
  • Maple syrup and a pinch of clove

If you glaze at the start, some of it will run into the liquid. That is fine. It flavors the steam.

Step 6: Cover And Cook On Low

Set the crock pot to low and cover it. Do not open the lid during cooking. Every time you peek, you lose heat and add time.

Cook times vary by size and whether the ham is bone-in or boneless. Use this as a guide:

  • 3 to 4 pound ham: 3 to 4 hours on low
  • 5 to 7 pound ham: 4 to 6 hours on low
  • 8 pound ham or larger: cut in half or use two pots

High heat works too, but low is safer. High can toughen the edges of an already cooked ham.

Step 7: Check The Internal Temperature

This is the most important step. A fully cooked ham only needs to reach 140°F (60°C) to be safely reheated.

Stick an instant-read thermometer into the thickest part, away from bone and fat. If it reads 140°F, its done.

If its below that, keep cooking and check again in 20 to 30 minutes.

Step 8: Rest Before Slicing

Turn off the crock pot and let the ham rest for 10 to 15 minutes. This lets the juices settle so they dont run out when you cut.

Then slice against the grain if its a whole ham. Spiral hams are already cut, so just separate the slices.

Common Mistakes To Avoid

Most problems with crock pot ham come down to a few easy fixes.

  • No liquid in the pot: the ham dries out and sticks
  • Cooking too long: it turns mushy and falls apart
  • Opening the lid often: adds 20 to 30 minutes each time
  • Skipping the thermometer: you cant guess doneness by look
  • Using a ham that is too big: uneven heating and a lid that wont close

Also, check the label. If your ham says “cook before eating” it is not fully cooked and needs a higher internal temperature. This guide is only for hams labeled fully cooked or ready to eat.

How To Serve And Store Leftovers

Let the ham cool slightly, then slice and serve. It pairs well with mashed potatoes, green beans, or rolls.

Store leftovers in a sealed container in the fridge for 3 to 4 days. You can also freeze sliced ham for up to 2 months.

To reheat, warm slices in a covered skillet with a splash of broth. Avoid the microwave on high, it makes the meat rubbery.

Final Tips For A Perfect Crock Pot Ham

Use low heat, keep the lid on, and trust your thermometer over the clock. A 5 pound ham usually lands around 4 to 5 hours, but your crock pot runs at its own pace.

If you want a thicker glaze, mix a little cornstarch with water and stir it into the juices at the end. Spoon that over the slices before serving.

With this method, a fully cooked ham comes out warm, moist, and ready to feed a crowd with almost no effort on your part.
