For a small pressure cooker ham, use a 3-pound boneless, fully cooked ham and a pressure-cooker recipe written for your model. One Instant Pot recipe cooks this size for 8 minutes at pressure, followed by about 15 minutes of natural release, then finishes it with a glaze under the broiler. Cooker size, pressure level, ham shape, and product label matter, so treat those timings as model-specific—not universal.
Before you begin
- Check the package. This guide is for a fully cooked, boneless ham. Do not use these timings for raw or “cook before eating” ham.
- Check that the ham and any cooking pan fit without exceeding the cooker’s max-fill line. Follow the manufacturer’s directions for minimum liquid, pressure setting, and release method.
- Have a food thermometer ready. USDA guidance says fully cooked ham packaged in a USDA-inspected plant should be reheated to 140°F; fully cooked ham that was repackaged elsewhere should reach 165°F. Follow any more specific package directions.
Pressure-cooker method for a 3-pound fully cooked ham
- Pour the minimum liquid required by your cooker into the inner pot. Instant Pot’s recipe uses ½ cup apple cider; water or broth may be used only if your cooker manual allows it.
- Place the ham in a shallow oven-safe pan if that is how your cooker’s rack and manual specify. Brush with a glaze made from brown sugar, mustard, and honey, or use the glaze from the recipe you are following.
- Lock the lid and set the valve as directed by your model. For the Instant Pot recipe linked below, the program is 8 minutes at pressure, followed by a natural pressure release of about 15 minutes. Use a different timing only when it comes from your own cooker’s instructions or a recipe designed for that exact model and ham size.
- Release any remaining pressure only as your manual directs. Open the lid away from your face, then check the ham’s center temperature without touching the probe to the pan.
- If the ham is below the temperature required for its package type, continue heating in a method allowed by your cooker and recheck. For a browned glaze, move the ham to a baking sheet and broil briefly, watching continuously so the sugar does not burn.
Why the package label matters
“Fully cooked” and “cook before eating” are not interchangeable. The temperature goal for reheating a ready-to-eat ham differs from the safe endpoint for raw ham. Raw fresh ham should reach at least 145°F and rest for 3 minutes; it needs a recipe written for raw ham rather than the short reheating method above. USDA’s ham and food-safety guidance explains the temperatures and product categories.
Useful tool
A thermometer helps verify the center temperature without guessing from cooking time or appearance. You can compare the ThermoPro digital instant-read meat thermometer for checking the thickest part of the ham. This is an affiliate link; Gear Cookware may earn a commission at no extra cost to you.

Quick answer
A 3-pound fully cooked boneless ham can take about 8 minutes at pressure in the specific Instant Pot recipe cited here, plus about 15 minutes for natural release. Confirm your cooker’s manual and the ham label, and verify the correct internal temperature before serving. These timings do not apply to raw ham or every pressure cooker.
