Step-by-Step Instructions

Step 1 — Slice and Prepare Onions

Thinly slice 4 large yellow onions. Uniform slices ensure even caramelization. Use a sharp knife for safety and consistency.

Tip: A mandoline can speed up slicing, but always use the guard to protect your fingers.

Step 2 — Caramelize the Onions

Melt 3 tablespoons of butter with 1 tablespoon of olive oil in a large Dutch oven over medium-low heat. Add the sliced onions and stir to coat.

Cook slowly for 40–50 minutes, stirring occasionally, until the onions are deeply golden brown and sweet. Do not rush this step—low and slow is key for perfect caramelization.

Step 3 — Deglaze the Pot

Add ½ cup of dry white wine or sherry to the caramelized onions. Scrape the bottom of the pot to lift all the flavorful browned bits.

Let the liquid reduce by half, about 3–5 minutes. This builds a rich foundation for your Easy French Onion Soup.

Step 4 — Add Broth and Simmer

Pour in 6 cups of beef broth and 2 cups of chicken broth. Bring to a gentle simmer over medium heat.

Season with 1 teaspoon of fresh thyme, 1 bay leaf, and salt and pepper to taste. Simmer uncovered for 30 minutes to allow flavors to meld.

Step 5 — Prepare the Bread and Cheese

While the soup simmers, slice a baguette into 1-inch thick rounds. Toast them in a 375°F oven until crisp and lightly browned, about 10 minutes.

Grate 2 cups of Gruyère cheese. This cheese melts beautifully and adds authentic flavor to your Easy French Onion Soup.

Step 6 — Assemble and Broil

Ladle the hot soup into oven-safe bowls. Place 1–2 toasted baguette slices on top of each portion.

Generously cover the bread with grated Gruyère. Place bowls on a baking sheet and broil on high for 2–4 minutes, until the cheese is bubbly and golden.

Step 7 — Serve Immediately

Carefully remove the hot bowls from the oven. Let them rest for 1 minute before serving.

Tip: The soup will be extremely hot. Enjoy your homemade Easy French Onion Soup with a spoon and plenty of napkins.

Common Mistakes to Avoid

• Mistake: Rushing the onion caramelization. Fix: Cook onions low and slow for 30-45 minutes until deeply golden brown and sweet.
• Mistake: Using the wrong type of onion. Fix: Stick with yellow onions for their ideal balance of sweetness and pungency when cooked.
• Mistake: Skipping the deglazing step. Fix: Scrape the flavorful browned bits from the pot with wine or sherry to build a rich base.
• Mistake: Using a weak, unseasoned broth. Fix: Use a high-quality beef broth and season well with salt, pepper, and a touch of thyme.
• Mistake: Choosing the wrong bread for the topping. Fix: Use a sturdy, thick-sliced baguette that can hold up to the soup without getting soggy.
• Mistake: Not toasting the bread before adding it. Fix: Lightly toast or broil the bread slices to create a barrier against sogginess.
• Mistake: Using pre-shredded cheese. Fix: Always grate Gruyère or Swiss cheese fresh for optimal melting and browning.
• Mistake: Broiling the cheese topping too far from the heat. Fix: Place bowls close to the broiler element for a quick, bubbly, golden-brown crust.

Storing Tips

• Fridge: Cool your Easy French Onion Soup completely, then transfer to an airtight container. It will keep for 3-4 days.
• Freezer: For longer storage, freeze in a freezer-safe container or heavy-duty bag for up to 3 months. Thaw in the refrigerator before reheating.
• Reheat: Reheat soup on the stovetop over medium heat, 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.
