Kitchen Princess is a manga by Natsumi Ando and Miyuki Kobayashi in which every chapter is named after a dish. This is our own quick, family-friendly version of that dish, not the recipe from the book.
Classic onion soup cooks its onions slowly for about 45 minutes until they turn deep brown. Our quick version is lighter and sweeter. For a deeper color and flavor, stir a teaspoon of soy sauce into the broth.
Make it a learning moment: why do onions make your eyes water? Cutting them releases a gas that stings. Chilling the onion first helps.
