French Onion Soup is a timeless, cozy dish thatβs steeped in history and packed with rich, savory flavor. With its caramelized onions, hearty broth, crispy bread, and gooey melted cheese, it’s more than just a starterβit’s a soul-warming experience. Letβs explore the ingredients, preparation, and everything else you need to know about this iconic soup.
π§ INGREDIENTS EXPLAINED
Hereβs a breakdown of what goes into a traditional French Onion Soup and why each ingredient matters:
4 Large Onions (thinly sliced): The foundation of the soup. Yellow onions are most commonly used for their balance of sweetness and savoriness. Slow caramelization is key to unlocking their deep, rich flavor.
2 Tbsp Butter + 1 Tbsp Olive Oil: This combination provides flavor and ensures the onions donβt burn during the long caramelization process.
2 Cloves Garlic (minced): Adds a subtle layer of aromatic flavor that complements the onions.
1 Tsp Fresh Thyme (or Β½ Tsp Dried): A classic herb in French cuisine that adds earthiness and fragrance.
1 Bay Leaf: Brings a subtle depth and complexity to the broth.
4 Cups Beef Broth + 1 Cup Chicken Broth: The dual broth combination balances richness (beef) with lightness (chicken), giving the soup a well-rounded base.
Β½ Cup Dry White Wine (optional): Adds acidity and brightness to cut through the richness. A splash of sherry or brandy can also be used.
Salt and Black Pepper: Enhances and balances all the flavors.
8 Slices Baguette or French Bread (toasted): Acts as a delicious βraftβ for the cheese. Toasting ensures it doesnβt become soggy immediately.
1½ Cups Shredded Gruyère Cheese: Nutty, melty, and golden when broiled. Gruyère is traditional, but Swiss or a blend with mozzarella can work in a pinch.
πͺ METHOD OF PREPARATION
Step-by-Step Instructions:
- Caramelize the Onions
In a large, heavy-bottomed pot, melt butter with olive oil over medium heat. Add onions and a pinch of salt. Cook slowly, stirring often, until onions are golden brown and caramelized (30β40 minutes). Donβt rush thisβitβs where all the magic happens. - Add Garlic and Herbs
Stir in minced garlic, thyme, and the bay leaf. Cook for 1β2 minutes until fragrant. - Deglaze and Simmer
Pour in the white wine (if using) to deglaze the panβscraping up the brown bits stuck at the bottom. Add beef and chicken broths. Bring to a boil, then lower to a simmer. Simmer uncovered for 15β20 minutes. Adjust seasoning with salt and pepper. - Toast Bread and Prepare Cheese
While the soup simmers, toast your baguette slices until crispy. Shred the Gruyère cheese and set aside. - Assemble and Broil
Ladle the hot soup into oven-safe bowls. Place a slice of toast on top of each. Sprinkle generously with cheese. Broil under high heat for 2β3 minutes, or until the cheese is bubbly and golden. - Serve with Care
Let bowls cool slightly before servingβtheyβll be very hot. Serve with extra bread on the side if desired.
π½οΈ TIPS FOR THE BEST FRENCH ONION SOUP
Low and slow is the mantra for caramelizing onions. Donβt rush it, or youβll miss out on the deep, sweet flavor.
For a vegetarian version, substitute the broth with rich mushroom or vegetable stock.
If you donβt have oven-safe bowls, toast the bread with cheese separately and place it on top after ladling the soup.
