    FAQs

    Do I need to line or spray my slow cooker?

    I always recommend either lining or spraying your slow cooker before cooking to make cleanup much easier.

    How will I know that my steak is done?

    As long as you have followed the cooking time in the recipe, your steak should be fully cooked. If you want to double-check, feel free to cut into a piece to see if it is done.

    Where can I find sesame oil?

    Sesame oil can be found with the other oils in most grocery stores. If you can’t find it there, check by the oriental foods.

    Can I use a type of steak other than flank steak?

    You can, but I recommend flank steak. It stays very tender when cooked in the slow cooker, unlike some other steaks, like sirloin.
