Long, slow cooking is the secret
to perfect caramelized onions, and
a slow cooker is a great way to get
the job done. Use the first part of
the recipe to make just the
caramelized onions to use in other
recipes, or add the broth and other
ingredients to make a rich-tasting
onion soup. Use a gluten-free bread
to make this recipe gluten-free. To
make this recipe soy-free, omit the
Worcestershire sauce and use a
soy-free sauce (purchased or
homemade, [>]) or add some
soy-free vegetable broth base to
additional salt, and use a soy-free
vegan cheese. GLUTEN-FREE OPTION
