Step‑by‑Step Instructions for Ultimate Easy French Onion Soup

Step 1: Caramelize the Onions
In a large skillet, melt 2 tablespoons of butter and 1 tablespoon of olive oil over medium-low heat. Add 4 to 5 sliced yellow onions, 2 sprigs of fresh thyme, and 1 bay leaf. Cook the onions slowly, stirring every 10 minutes, for about 45 minutes until they are deeply caramelized and liquid has evaporated. Season with salt to taste, allowing their sweetness to shine through in your French Onion Soup.

Step 2: Deglaze and Simmer
Once the onions are caramelized to a beautiful golden brown, pour in ½ cup of white wine to deglaze the pan, scraping up any flavorful bits stuck to the bottom. Bring this mixture to a simmer and let it cook for about 2-3 minutes to reduce slightly. Next, add 6 cups of beef broth (or vegetable broth for a vegetarian option) and bring to a gentle boil. Reduce heat and let it simmer for another 15 minutes, allowing the flavors to meld together.

Step 3: Prepare for Broiling
As the soup simmers, preheat your oven’s broiler. Divide the hot soup among oven-safe bowls, ensuring equal portions. Top each bowl with toasted slices of baguette, which should be slightly crispy. Generously sprinkle 1 to 1½ cups of grated Gruyère cheese over the bread, creating a luscious cheesy topping that will melt beautifully, adding richness to your French Onion Soup.

Step 4: Broil the Soup
Carefully place the bowls under the broiler for approximately 3 to 5 minutes. Keep a close eye on them, as you want the cheese to melt and become bubbly with a golden crust, but not burned. This final touch adds a delightful texture contrast to the warm, savory soup beneath.

Step 5: Garnish and Serve
Once the cheese is perfectly melted and slightly browned, carefully remove the bowls from the oven. Allow them to cool for a moment, then garnish with extra thyme for a fresh touch if desired. Serve your Ultimate Easy French Onion Soup hot, allowing everyone to enjoy the irresistible flavors and comforting aromas that fill the air.

Storage Tips for French Onion Soup

Fridge: Store leftovers in an airtight container for up to 3 days. Be sure to let it cool completely before sealing to prevent moisture buildup.
Freezer: You can freeze the soup for up to 2 months. Allow it to cool, then transfer to freezer-safe containers, leaving some space for expansion.
Reheating: When ready to enjoy, thaw in the fridge overnight. Reheat gently on the stovetop over low heat, adding a splash of broth to restore creaminess as needed.
Topping Storage: Keep cheese and baguette toppings separate in the fridge. Toast the baguette again when serving to maintain its crunch over the warm, comforting French Onion Soup.

Expert Tips for French Onion Soup
