how long to slow cook a ham
Slow cooking a ham, typically a pre-cooked spiral-cut or bone-in variety, usually takes 4 to 6 hours on low in a crockpot until it reaches an internal temperature of 140°F for safety and tenderness.
Cooking Times by Size
Time varies by ham weight to avoid dryness—always use a meat thermometer.
- 4-6 lb ham : 2-3 hours on low.
- 7-10 lb ham : 4-6 hours on low.
- Smaller (under 4 lb) : 2-3 hours; check early to prevent overcooking.
Larger hams may need up to 6 hours, but flip and baste halfway for even heating.
Preparation Steps
- Place pineapple juice or soda in the slow cooker base for moisture.
- Score and glaze the ham with brown sugar, mustard, honey, or cloves.
- Cook covered on low; rest 15 minutes post-cook before slicing.
Safety Tips
FDA guidelines stress reheating pre-cooked hams to 140°F—overcooking dries it out. Avoid high settings to retain juices; low and slow is key for holiday perfection.
