Cooking ham to perfection requires precision and care. One of the most common questions is: how long to cook a cooked ham at 325 degrees? This guide will walk you through every aspect of cooking pre-cooked ham, ensuring it turns out juicy, flavorful, and safe to eat.
Why Cooking Ham at 325 Degrees is Ideal
Reheating pre-cooked ham at 325°F is highly recommended because it allows the ham to warm evenly without drying out. According to the USDA, pre-cooked ham should reach an internal temperature of 140°F. This ensures food safety while preserving the ham’s tender texture.
Cooking at a higher temperature, such as 350°F, can lead to uneven heating or drying out of the ham. For a more in-depth comparison of cooking temperatures, refer to Do You Cook a Ham at 325 or 350?.
Understanding Pre-Cooked Hams
What is a Pre-Cooked Ham?
A pre-cooked ham has already undergone processing to make it safe to eat. These hams can be smoked, cured, or fully cooked during manufacturing. Types of pre-cooked ham include:
- Bone-in Ham: Known for its flavor and juicy texture.
- Boneless Ham: Easier to carve and ideal for smaller gatherings.
- Spiral-Cut Ham: Pre-sliced for convenience, but requires careful heating to avoid drying out.

Factors That Affect How Long to Cook a Cooked Ham at 325 Degrees
Cooking time for ham at 325°F depends on several key factors:
1. Ham Size and Its Impact on Cooking Time at 325°F
Larger hams, such as a whole bone-in ham, require more time to heat through. As a general rule:
- Bone-in hams: 15–18 minutes per pound.
- Boneless hams: 12–15 minutes per pound.
For spiral-cut hams, time is slightly reduced due to the pre-sliced structure.
2. Types of Hams and Their Ideal Cooking Times at 325 Degrees
The type of ham also influences cooking time:
- Spiral-cut hams heat faster but need close monitoring to avoid overcooking.
- Bone-in hams take longer due to the dense bone, which retains heat.

3. Preparation Style and Timing for Cooking Ham at 325°F
- Covered or Uncovered: Covering the ham in foil reduces cooking time by retaining moisture.
- Glazed or Unglazed: Glazes add complexity to the process as they require application during the last 20 minutes to avoid burning.
Detailed Guide on How Long to Cook a Cooked Ham at 325 Degrees
Preparing the Ham
- Trim Excess Fat
Remove any thick layers of fat, leaving a thin layer for flavor. - Score the Ham
Use a sharp knife to make shallow cuts in a diamond pattern across the surface. This allows glaze to penetrate and enhances presentation. - Add Liquid
Place the ham in a roasting pan with ½ inch of water, broth, or apple juice. This prevents drying and creates a steaming effect.
Cooking the Ham
- Preheat the Oven
Set your oven to 325°F and allow it to preheat. - Cover the Ham
Cover the ham tightly with aluminum foil to retain moisture. For spiral-cut hams, wrapping them fully in foil is recommended. - Calculate Cooking Time
Use the weight of your ham to determine the total cooking time:- Bone-in: 15–18 minutes per pound.
- Boneless: 12–15 minutes per pound.
- Spiral-cut: 10–18 minutes per pound.
- Monitor Internal Temperature
Insert a meat thermometer into the thickest part of the ham, avoiding the bone. The internal temperature should reach 140°F.
Glazing Tips to Enhance Flavor While Cooking Ham at 325 Degrees
When to Apply the Glaze
Timing is critical when glazing. If you apply it too early, the sugars in the glaze can burn, resulting in a bitter crust. To avoid this, apply the glaze during the last 20–30 minutes of cooking. This allows enough time for the glaze to caramelize and adhere to the ham without charring.
How to Prepare the Glaze
A well-balanced glaze combines sweet, tangy, and savory flavors. Popular ingredients include:
- Sweeteners: Brown sugar, honey, maple syrup, or molasses.
- Tangy Elements: Dijon mustard, pineapple juice, or apple cider vinegar.
- Seasonings: Ground cloves, cinnamon, nutmeg, or fresh herbs like rosemary.
For instance, a classic glaze might include:
- 1 cup brown sugar
- ¼ cup honey
- 2 tablespoons Dijon mustard
- 1 teaspoon ground cloves
Mix these ingredients in a small saucepan over low heat until the sugar dissolves and the glaze becomes slightly thickened.
How to Apply the Glaze
- Remove the Ham from the Oven
About 20–30 minutes before the ham is fully cooked, remove it from the oven and uncover it. - Brush the Glaze Generously
Using a silicone brush, coat the entire surface of the ham with a thick layer of glaze. Be sure to get into the scored cuts for added flavor. - Return to the Oven
Place the ham back in the oven, uncovered, for the final 20–30 minutes. This allows the glaze to caramelize beautifully. - Repeat if Desired
For an extra-glossy finish, repeat the glazing process halfway through the final 20–30 minutes of cooking.
Achieving the Perfect Caramelization
To create a deep, caramelized crust, you can:
- Turn on the broiler for the last 3–5 minutes of cooking. Keep a close eye on the ham to prevent burning.
- Use a kitchen torch to caramelize the glaze after the ham has finished cooking.
Glazing Tips
- Layering Flavor: For added complexity, you can brush the ham with a thin layer of mustard before applying the glaze.
- Scoring the Ham: Scoring the surface in a diamond pattern ensures the glaze penetrates deeper, flavoring the meat beneath the surface.
- Adding Garnishes: After glazing, consider garnishing the ham with pineapple rings, maraschino cherries, or fresh herbs for a festive presentation.
Popular Glaze Variations
Here are some tried-and-true glaze recipes you can experiment with:
- Honey and Brown Sugar Glaze
A simple yet classic combination of brown sugar, honey, and a touch of mustard creates a sticky, sweet crust. - Pineapple and Cherry Glaze
Blend pineapple juice, maraschino cherry syrup, and a hint of ginger for a tropical twist. - Maple Mustard Glaze
Combine maple syrup, Dijon mustard, and a dash of cayenne for a sweet and spicy balance. - Bourbon Glaze
Simmer brown sugar, honey, and a splash of bourbon for a glaze with a rich, smoky undertone.
Post-Glazing Care
Once the ham is cooked and glazed, allow it to rest for 15–20 minutes before serving. This resting period not only helps the juices redistribute but also allows the glaze to set, creating a beautiful, sticky crust that clings to each slice.
By carefully timing and applying your glaze, you’ll transform your ham into a centerpiece worthy of any special occasion. Whether you prefer a traditional brown sugar glaze or a creative bourbon variation, the key is to let the natural flavors of the ham shine through, enhanced by the perfect glossy finish.

Resting the Ham
After cooking, let the ham rest for 15–20 minutes. This allows juices to redistribute, ensuring every slice is moist and flavorful.
Avoiding Common Mistakes
Here are some common mistakes to avoid when cooking ham:
- Skipping the Thermometer
Always use a meat thermometer to ensure the ham is reheated safely to 140°F. - Overcooking the Ham
Follow the time and temperature guidelines closely to prevent dryness. - Glazing Too Early
Applying glaze too early can result in burning. Save this step for the last 20 minutes of cooking. - Forgetting to Cover
Covering the ham with foil retains moisture, preventing the outer layer from drying out.
Complementary Side Dishes
A well-cooked ham pairs beautifully with these sides:
- Roasted Vegetables
Carrots, Brussels sprouts, and sweet potatoes caramelize perfectly alongside ham. - Mashed Potatoes and Gravy
Creamy mashed potatoes complement the salty-sweet flavor of ham. - Baked Cornbread
