Step‑by‑Step Instructions for Lazy French Onion Soup

Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This temperature will help caramelize the onions beautifully, allowing them to develop a rich, sweet flavor. While the oven is heating, gather a large baking dish or sheet that can comfortably hold your sliced onions.

Step 2: Prepare the Onions
Slice your yellow onions into thin rings, ensuring even thickness for uniform cooking. In a large bowl, combine the sliced onions with butter, olive oil, salt, and pepper. Toss everything together until the onions are well-coated, then spread them evenly in the prepared baking dish for even roasting.

Step 3: Roast the Onions
Place the baking dish in the preheated oven and roast the onions for approximately 45 minutes to 1 hour. Stir the onions halfway through to promote even browning. When done, they should be golden brown, fragrant, and caramelized, showcasing their sweet transformation.

Step 4: Add the Sherry
Once your onions are beautifully caramelized, carefully remove them from the oven. Pour in the dry sherry, stirring well to deglaze the pan. The sherry will enhance the flavor complexity of your Lazy French Onion Soup as it absorbs the rich browning from the onions, creating a more robust broth.

Step 5: Incorporate the Broth
Next, pour in the beef broth, stirring the mixture gently to blend all the flavors together. Bring the soup to a simmer over medium heat and let it cook for about 30 minutes. As it simmers, you’ll notice a delightful aroma filling your kitchen, signaling the comfort to come.

Step 6: Prepare the Baguette Topping
While the soup simmers, slice the baguette into thick rounds. Place the slices on a baking sheet, and top each with a generous layer of Gruyère cheese. Set aside, as these will be toasted to perfection right before serving, giving you a delicious crunchy topping for your Lazy French Onion Soup.

Step 7: Toast the Cheese Topping
After the soup has simmered, turn on your broiler. Place the baking sheet with the prepared baguette slices under the broiler for about 3–5 minutes or until the cheese is melted and bubbly, and the bread has achieved a lovely golden color. Keep a close eye to prevent burning.

Step 8: Serve and Enjoy
Ladle the hot Lazy French Onion Soup into bowls, topping each with the prepared, cheesy baguette slices. Feel free to garnish with additional cheese if desired. Serve the soup immediately while hot, delighting in the fusion of the rich broth, sweet onions, and crunchy, cheesy topping!
