• Herb twists: Experiment with rosemary or bay leaves instead of thyme for an earthy aroma.
• Spicy kick: Add a pinch of cayenne or smoked paprika for warmth and depth.
• Wine-free option: Use extra broth or a splash of apple cider vinegar as a non-alcoholic substitute.

How to Make French Onion Soup

Step 1: Caramelize the Onions

Start by thinly slicing the yellow onions and cooking them slowly in butter over medium-low heat. Stir frequently until they turn golden brown and soft, releasing their natural sweetness—this process usually takes about 40 minutes but is key to building the soup’s flavor.

Step 2: Deglaze the Pan

Once the onions are caramelized, add dry white wine or brandy to the pan. This step helps lift all the flavorful browned bits stuck to the bottom and adds brightness to balance the sweetness.

Step 3: Add the Broth and Herbs

Pour in the beef or vegetable broth along with the fresh thyme and minced garlic. Bring the mixture to a simmer and let it cook gently for 20-30 minutes so the flavors meld beautifully.

Step 4: Prepare the Bread and Cheese

While the soup simmers, slice the baguette and toast the slices until crisp. Grate the Gruyere cheese—this will later create a golden crust on top of the soup.

Step 5: Assemble and Broil

Ladle the hot soup into oven-safe bowls, top each with toasted bread, and pile on the Gruyere generously. Place the bowls under a broiler until the cheese is bubbly and golden, then serve immediately for maximum gooey goodness.

Pro Tips for Making French Onion Soup

• Take your time caramelizing: Cook onions slowly to avoid bitterness and develop deep sweetness.
• Use quality broth: A rich, flavorful stock makes all the difference in the soup’s base.
• Don’t skip the deglazing step: It unlocks layers of flavor stuck to the pan.
• Broil carefully: Watch the cheese closely to prevent burning while achieving the perfect golden crust.
• Serve immediately: The cheese topping is at its best right out of the oven, melty and delicious.

How to Serve French Onion Soup

Garnishes

Classic French Onion Soup shines with simple garnishes like a sprinkle of fresh thyme, cracked black pepper, or a dash of freshly grated Parmesan. These add color and a subtle extra kick without overpowering the main flavors.

Side Dishes

This soup pairs beautifully with light green salads dressed in vinaigrette or roasted vegetables to balance the richness. Crusty bread on the side also complements this hearty dish perfectly.

Creative Ways to Present

Serve French Onion Soup in individual mini crockpots for elegant parties or in rustic French onion bread bowls for a trendy twist. You can also layer the cheese and bread on top before reheating for a quick, cozy meal.

Make Ahead and Storage

Storing Leftovers

Keep leftover soup in an airtight container in the refrigerator for up to 3 days. Store the toasted bread and grated cheese separately to retain their texture when reheating.

Freezing

French Onion Soup freezes well without the bread and cheese toppings. Pour the cooled soup into freezer-safe containers and freeze for up to 3 months. Add bread and cheese fresh upon serving.

Reheating

Reheat soup gently on the stove to avoid burning or overreducing the broth. Add toppings afterward and place under a broiler or in a hot oven just long enough to melt the cheese.
