I brought my sausage dip to a church supper and left it on warm all evening. A nurse in our group gently told me how long it really should sit there.
What Warm Is For
The warm setting keeps already-cooked food hot. It’s not for cooking raw food.
Keeping Food Safe
Food-safety guidance says hot food should stay at 140°F or hotter. Most slow cooker warm settings are designed to hold food above that.
Many slow cooker makers suggest keeping food on warm for no more than about 4 hours, because food can dry out and lose quality. Check your own slow cooker’s manual.
Tips for Potlucks
- Cook the food fully first, then switch to warm.
- Stir now and then, and add a splash of liquid if it starts to dry.
- Keep the lid on between servings.
Leftovers
Don’t let leftovers cool down in the slow cooker. Move them to shallow containers and refrigerate within 2 hours.
