Step-by-Step Instructions

Step 1 — Slice the Onions

Peel and thinly slice 4 large yellow onions. Uniform slices ensure even caramelization. Use a sharp knife for safety and consistent results.

Step 2 — Caramelize the Onions

Melt 3 tablespoons of butter in a large pot over medium heat. Add the sliced onions and cook, stirring occasionally, for about 30-40 minutes until deeply golden brown. Do not rush this step; proper caramelization is key for flavor.

Step 3 — Deglaze the Pot

Add ½ cup of dry white wine to the caramelized onions, scraping the bottom of the pot to lift all the browned bits. Cook for 2-3 minutes until the wine has mostly evaporated. This builds a rich flavor base for your Easy French Onion Soup.

Step 4 — Add Broth and Simmer

Pour in 6 cups of beef broth and add 2 sprigs of fresh thyme. Bring to a boil, then reduce heat and simmer uncovered for 30 minutes. The soup should be slightly reduced and flavorful.

Step 5 — Season the Soup

Remove the thyme sprigs. Season with salt and black pepper to taste. For best flavor, start with ½ teaspoon of salt and adjust as needed after tasting.

Step 6 — Prepare the Toppings

Slice a baguette into 1-inch thick pieces. Toast them until golden and crisp. Grate 1½ cups of Gruyère cheese for melting over the soup.

Step 7 — Assemble and Broil

Ladle the hot soup into oven-safe bowls. Top each with a toasted baguette slice and a generous amount of grated Gruyère. Place under a broiler for 2-3 minutes until the cheese is bubbly and golden brown.

Step 8 — Serve Immediately

Carefully remove the bowls from the oven using oven mitts. Let cool for 1-2 minutes before serving. This Easy French Onion Soup is best enjoyed hot with the cheese stretchy and aromatic.

Common Mistakes to Avoid

• Mistake: Rushing the caramelization process. Fix: Cook onions slowly over medium-low heat for 30–45 minutes until deeply golden brown and sweet.
• Mistake: Using the wrong type of onion. Fix: Choose yellow onions for their ideal balance of sweetness and pungency when caramelized.
• Mistake: Skipping the deglazing step. Fix: Scrape the flavorful browned bits from the pot with wine or sherry to build a rich foundation.
• Mistake: Using a weak, unseasoned broth. Fix: Opt for a high-quality beef broth and season well, as the broth is the soup’s backbone.
• Mistake: Overcrowding the pot with onions. Fix: Use a large, wide pot so onions caramelize evenly instead of steaming.
• Mistake: Adding raw cheese directly to hot soup. Fix: Place cheese on toasted bread and broil until bubbly, then float it on the soup.
• Mistake: Not toasting the bread before adding. Fix: Toast or bake bread slices until crisp so they hold up under the broth and cheese.
• Mistake: Underseasoning throughout the process. Fix: Season in layers—while cooking onions, after adding broth, and before serving.
• Mistake: Using high heat to melt the cheese topping. Fix: Broil briefly just until the cheese is melted and spotty brown for perfect texture.

Storing Tips

• Fridge: Cool your Easy French Onion Soup completely, then transfer to an airtight container. It will keep for 3-4 days in the refrigerator.
• Freezer: For longer storage, freeze the soup in a freezer-safe container for up to 3 months. Leave about an inch of headspace to allow for expansion.
• Reheat: Thaw frozen soup in the refrigerator overnight. Reheat gently on the stovetop or in the microwave, stirring occasionally, until it reaches a safe internal temperature of 165°F (74°C).

Always store your soup promptly after it has cooled to room temperature to ensure food safety and the best flavor.
