This French Onion Soup(Crock-Pot) relies on simple, everyday ingredients such as large onions, thinly sliced, hot water, worcestershire sauce and salt (i don't use salt). It comes together quickly and makes 4 servings, at about 329 kcal each. The step-by-step instructions below are written to be easy to follow, even on a busy day.
It works as a light main on its own or as a starter alongside crusty bread, and it's just as good for a cozy night in as it is for feeding a crowd. Leftovers keep well, so it's a smart choice for meal prep too.
