A delightful onion soup topped with melted mozzarella, perfect for a cozy meal.
Melt the butter in a large saucepan over medium heat.
Ensure the butter doesn't brown for a smoother flavor.
Add the minced garlic, sliced leeks, and onions to the saucepan. Sauté until softened, about 15 minutes.
Stir occasionally to prevent sticking.
Add the salt, beef broth, water, black pepper, and hot sauce to the saucepan. Bring to a boil.
Taste and adjust seasoning as needed.
Reduce the heat to low, cover, and simmer for 30 minutes.
Simmering allows the flavors to meld together.
Preheat the oven to broil. Ladle the soup into oven-proof bowls.
Ensure the bowls are safe for high heat.
Top each bowl with a slice of toasted bread and a generous amount of shredded mozzarella cheese.
Press the cheese slightly to keep it in place.
Broil in the oven until the cheese is melted and golden brown.
Keep an eye on the cheese to prevent burning.
Serve hot and enjoy your savory onion soup.
Garnish with fresh herbs like parsley for added color.
