Gratinéed Onion Soup
🛒Ingredients (Grocery List)
4 tbsp (1/2 stick) Butter
3 Large Onions, thinly sliced
1 tbsp all-purpose Flour
Salt and Pepper
4 slices Country Bread, each cut into 4 pieces
1/2 cut shredded Gruyère or Swiss Cheese
🍴Serves: 4
⏰Prep Time: 15 min
⏱️Cook Time: 45 min
🥣Instructions
1. In a large saucepan, melt 2 tablespoons of the Butter over medium heat. Add the Onions and cook until lightly browned, about 20 minutes. Sprinkle in the Flour and cook, stirring until browned. Stir in 6 cups of water and season with Salt and Pepper. Bring to a boil, then reduce the heat to low and simmer for 20 minutes.
2. In a large skillet, melt the remaining 2 tablespoons Butter over medium heat. Add the Bread and cook until golden, about 3 minutes per side.
3. Preheat the broiler. Ladle the soup into a deep baking dish or ovenproof bowls and set on a baking sheet. Float the Croutons in the soup and sprinkle with the Cheese. Broil 8 inches from the heat for about 2 minutes, or until melted and golden. Serve right away.
💡Tips
To prevent the Onions from sticking to the pan, stir in 1 or 2 tablespoons of cold water once they are lightly browned. Cover and simmer gently.
To save time, you can serve the soup without the Cheese Croutons. Or use plain toast instead. Alternatively. Top bowls of store-bought Onion Soup with homemade Cheese Croutons and broil them until melted and golden.
