Whether you need it for a side dish or for another recipe, this is a super easy way to carmelize onions without requiring you to stand over the oven for what always seems like forever.

6 large sweet onions, peel and stem ends removed
4 tbsp margarine or butter
10-oz can chicken or veggie broth

Place onions in slow cooker, top with butter and then pour the broth over top. Cover and cook on low for 12 hours.
