Both Instant Pots and slow cookers can produce some aroma while cooking, but the intensity of the smell can vary depending on what you're cooking and how well the appliance is sealed.
Slow cookers generally have a vented lid, which allows some of the cooking odors to escape into the surrounding area. As a result, you might notice the aroma of the food while it's cooking, and it can become more pronounced as the cooking time increases.
On the other hand, Instant Pots have a tightly sealed lid, which helps retain more of the cooking odors within the pot. While this can help reduce the overall smell in your kitchen, it doesn't eliminate it entirely. Certain ingredients, such as garlic, onions, or strong spices, may still release some scent, but it's usually not as noticeable as with a slow cooker.
It's worth noting that the smell during cooking can also be influenced by the type of food being prepared. Foods with strong aromas, like curry or certain meats, might be more likely to produce noticeable smells compared to others.
In both cases, keeping your kitchen well-ventilated can help dissipate any cooking odors more quickly. Using an exhaust fan or opening a window can be helpful if you want to reduce the lingering smell after cooking.
Overall, while there might be some differences in the intensity of cooking smells between Instant Pots and slow cookers, both appliances can contribute to some aroma in the kitchen while preparing meals.
