A suitable alternative to schmaltz in the chopped liver is a neutral oil like vegetable, canola or safflower. These oils contain less saturated fat than schmaltz, which means they are healthier for you and won't have the same strong flavor. The chopped liver can also be made with butter, margarine or cream cheese. If you want to keep it dairy-free, then try using non-dairy alternatives such as coconut oil, olive oil or avocado oil. Each of these options will still provide some flavor and richness to the chopped liver while keeping it healthier than traditional schmaltz.
