Costco's hams are renowned for their quality and size, making them a popular choice for holidays and large gatherings. But with such a substantial cut of meat, you might be wondering, "How long does it take to cook a Costco ham?" This guide will walk you through the process, ensuring you serve a perfectly cooked ham every time.
Before we dive into cooking times, it's essential to understand your ham. Costco offers two main types: bone-in and boneless, and spiral-sliced or unsliced. The cooking time can vary slightly depending on these factors.
Here are the general cooking times for Costco hams. Remember, these are estimates, and your ham's size and type may affect the cooking time.

| Ham Type | Cooking Time (at 325°F/165°C) |
|---|---|
| Bone-in, unsliced | 18-20 minutes per pound |
| Boneless, unsliced | 15-18 minutes per pound |
| Spiral-sliced (pre-cooked) | 10-12 minutes per pound to heat through |
To calculate the cooking time for your ham, weigh it and divide by the cooking rate (minutes per pound) from the table above. Then, multiply by 60 to convert minutes into hours. For example, a 10-pound bone-in ham would take approximately:
10 pounds * 18 minutes/pound = 180 minutes or 3 hours
Here are some tips to ensure your ham turns out perfectly:

Once cooked, your ham can be served warm or at room temperature. For leftovers, store in an airtight container in the refrigerator for up to 5 days. You can also freeze cooked ham for up to 2 months.
Now that you know how long it takes to cook a Costco ham, you're ready to impress your guests with a delicious, perfectly cooked centerpiece for your meal. Happy cooking!
